Process For Producing Corrosion Resistant Carbon Steel Razor Blades And Products Made Thereby

View page
US Patent:
41399420, Feb 20, 1979
Filed:
Dec 16, 1977
Appl. No.:
5/861275
Inventors:
Suri A. Sastri - Stow MA
Thomas G. Decker - Wellesley Hills MA
Richard McDonald - Scituate MA
Assignee:
The Gillette Company - Boston MA
International Classification:
B26B 2154
B05D 500
US Classification:
3034654
Abstract:
A process for producing long-lasting corrosion resistant carbon steel razor blades and the products made thereby. The process comprises first coating the cutting edges of the blades with chromium; and then immersing the blades in an electroless coating bath to provide a coating of a nickel-phosphorous, nickel- copper- phosphorous, cobalt-phosphorous or cobalt-nickel-phosphorous coating material on at least the bodies of the blades, the chromium coating preventing beading up of the coating material on the cutting edges of the blades to an extent that would require resharpening of the cutting edges. The blades may thereafter be overcoated with a carboxy-substituted silicone oil composition preferably comprising therein a long chain aliphatic acid, alcohol, amide and mixtures thereof.

Processes For Treating Cutting Edges

US Patent:
41226038, Oct 31, 1978
Filed:
Jun 3, 1977
Appl. No.:
5/803299
Inventors:
Suri A. Sastri - Stow MA
Assignee:
The Gillette Company - Boston MA
International Classification:
B26B 2154
US Classification:
303465
Abstract:
The present invention is concerned with processes for michrohoning cutting edges and especially those of razor blades, wherein the edges are subjected to sonic energy and especially ultrasonic energy while said edges are in contact with a slurry or dispersion of abrasive particles which have diameters of less than 3 microns. The sonic or ultrasonic energy is emitted from a horn having a corrugated end and the ridges of said corrugated end are oriented so as to be perpendicular to the edges of the razor blades as they pass the horn, said blades being stacked in a magazine in which their edges are substantially parallel to one another and their flat surfaces in face-to-face relationship.

Steve S. Hahn - Wellesley MA
Assignee:
The Gillette Company - Boston MA
International Classification:
B26B 2154
US Classification:
303465

Surface Coatings And Subcoats

View page
US Patent:
45566070, Dec 3, 1985
Filed:
Mar 28, 1984
Appl. No.:
6/594224
Inventors:
Suri A. Sastri - Lexington MA
International Classification:
C23C 910
C23C 500
C09D 300
US Classification:
428627
Abstract:
Coatings are disclosed (a) which are useful by themselves to substantially improve the surface properties of substrates to which they are applied and (b) which are useful as subcoats to substantially improve the bonding of coatings of nitrides, carbides and borides of titanium, hafnium and zirconium to such substrates. The coatings which are disclosed are novel materials characterized by a microcrystalline, single-phase, solid solution structure comprising: (a) about 20 to 70% by weight of at least one element from the group consisting of cobalt and nickel; (b) about 8 to 35% by weight of chromium; (c) about 3 to 20% by weight of at least one element from the group consisting of molybdenum and tungsten; and (d) about 0. 5 to 10% by weight of at least one element from the group consisting of carbon, nitrogen and boron.

Razor Blades

View page
US Patent:
41804201, Dec 25, 1979
Filed:
Dec 1, 1977
Appl. No.:
5/856732
Inventors:
Suri A. Sastri - Stow MA
Ben H. Alexander - Weston MA
Assignee:
The Gillette Company - Boston MA
International Classification:
C22C 3822
US Classification:
148 37
Abstract:
The instant disclosure is concerned with martensitic stainless steel cutting edges such as razor blades which have superior corrosion resistance and which, although containing only between 0. 30% to 0. 45% carbon have hardnesses which are equal or better than cutting edges made from martensitic stainless steels containing 0. 6% or more carbon which are widely sold commercially. Generally the blades are produced by treating them prior to hardening so that they will have a fine carbide microstructure comprising about 200 to about 500 carbides per 100 square microns, hardening them under conditions in which the fine microstructure will be substantially retained, i. e. subsequent to hardening they will still have about 200 to 500 carbides per 100 square microns, and forming the cutting edge.

Brazing Technology

View page
US Patent:
56647239, Sep 9, 1997
Filed:
Oct 27, 1995
Appl. No.:
8/549464
Inventors:
Suri A. Sastri - Lexington MA
International Classification:
B23K 3100
US Classification:
2281241
Abstract:
A method of braze joining a copper member to a substrate of metal or ceramic material is disclosed according to which a diffusion barrier coating as defined is applied to the substrate alone, and a selected brazing alloy is interposed between copper member and substrate, followed by a two-step heating treatment. In the first step the assembly is heated at a temperature and for a time sufficient to melt the brazing alloy and cause a bond to form between the brazing alloy and the copper member and between the brazing alloy and the substrate. In the second step the temperature is raised and maintained in the range from about 600. degree. C. to about 950. degree. C. in a "solutionizing heat treatment" (as defined) for a time sufficient to allow the brazing alloy to form an "extended solid solution" (as defined) with copper in a controlled fashion to convert the bond to a strong joint which is resistant to thermal stress.

Metal-Bonded, Carbon Fiber-Reinforced Composites

View page
US Patent:
54959799, Mar 5, 1996
Filed:
Jun 1, 1994
Appl. No.:
8/252601
Inventors:
Suri A. Sastri - Lexington MA
J. Paul Pemsler - Lexington MA
Richard A. Cooke - Framingham MA
John K. Litchfield - Bedford MA
Mark B. Smith - Ipswich MA
Assignee:
Surmet Corporation - Burlington MA
Castle Technology Corporation - Lexington MA
International Classification:
B23K 120
US Classification:
2281241
Abstract:
Metal bonded carbon fiber-reinforced composites are disclosed in which the metal and the composite are strongly bound by (1) providing a matrix-depleted zone in the composite of sufficient depth to provide a binding site for the metal to be bonded and then (2) infiltrating the metal into the matrix-free zone to fill a substantial portion of the zone and also provide a surface layer of metal, thereby forming a strong bond between the composite and the metal. The invention also includes the metal-bound composite itself, as well as the provision of a coating over the metal for high-temperature performance or for joining to other such composites or to other substrates.

Tubular Surgical Cutting Instruments With Coating

View page
US Patent:
56308264, May 20, 1997
Filed:
Mar 1, 1993
Appl. No.:
8/026123
Inventors:
Suri A. Sastri - Lexington MA
International Classification:
A61B 1732
US Classification:
606170
Abstract:
A surgical instrument for use in endoscopic surgical procedures and especially arthroscopic surgery having an outer elongated tubular member and a concentric inner elongated tubular member positioned in and rotatable within the outer tubular member having an opening in its distal end and the inner tubular member having a cutting edge positioned at its distal end so as to coincide with and be exposable through the opening in the outer tubular member to effect the cutting of tissue and the removal of the cut tissue by aspiration through the inner tubular member, a coating of a metal from the group consisting of silver and gold extending substantially around the circumferential surface of at least one of the outer surface of the inner tubular member or the inner surface of the outer tubular member, the metallic coating from the group consisting of silver and gold being of such thickness and extending a sufficient distance along the axial length of the member to which it is applied to provide a malleable surface which more precisely controls and facilitates the rotation of the inner tubular member within the outer tubular member so as to virtually eliminate the production of metallic wear debris which can make its way to the incision site resulting in undesirable contamination and which can also reduce the scoring of the walls that can lead to the seizure of the surgical tool.
