Remote Interconnection Box Utilizing Shielding Interconnecting Brackets

View page

US Patent:

48864641, Dec 12, 1989

Filed:

Oct 24, 1988

Appl. No.:

7/261580

Inventors:

Maurice F. Zetena - Bridgewater CT

International Classification:

H01R 924

US Classification:

439 98

Abstract:

An interconnection box is provided for use with a plurality of pairs of composite cables, the cables including a plurality of twisted pairs and shielding braid. The box includes a plurality of electroconductive support brackets mounted on the base, the brackets being insulated from the base, a pair of clamps mounted upon the bracket to receive the braid and hold it in electrical contact with the bracket, and a terminal block mounted on the bracket to interconnect the twisted pairs. This structure permits composite cables to be interconnected with a common shield for each pair of cables through the support bracket, and avoids ground currents between various of the pairs.

US Patent:

47618116, Aug 2, 1988

Filed:

Dec 22, 1986

Appl. No.:

6/944827

Inventors:

Maurice F. Zetena - Bridgewater CT

International Classification:

H04M 1100

US Classification:

379397

Abstract:

A networking system to interconnect computer terminals with a host computer, the system being capable of carrying data bits at high frequencies and being capable of readily having its interconnection pattern changed. The system includes a plurality of composite cables for transmission of the data bits, one such cable for each such computer terminal, each of the cables including at least two sets of twisted pair data lines and an associated drain line, each set of data lines being within a shielding sleeve, and said sleeves being isolated from one another. A distribution wiring board for interconnecting the cables with the host computer, the wiring board including a punch down block with multiple sets of aligned punch-down connectors for connecting the wires in the sets and the drain wires to the wiring board, means for grounding the drain wires, and a data board for changing the local area network formed by the cables and the computer terminals. The composite cables also includes telephone wires for providing telephone service at the computer terminals.

Modular Fiber Optics Raceway Permitting Flexible Installation

US Patent:

52715850, Dec 21, 1993

Filed:

Oct 1, 1990

Appl. No.:

7/591058

Inventors:

Maurice F. Zetena - Bridgewater CT

International Classification:

F16L 300

US Classification:

248 49

Abstract:

A fiber optics cable raceway is formed of main channel members and telescope members. The main channel members have a generally U-shaped cross-section with a base, sides, and, at the top, inwardly extending lips. The telescope members have the same cross-section, but are slightly larger so they can fit about the main channel members for a longitudinally sliding fit. By alternately, interfitting main members and telescope members and adjusting the length by telescopic sliding, a raceway of the desired length can quickly be assembled. Small locking clips can then be fitted about the respective overlapping lips of two members to prevent further sliding. The raceway can be installed below the floor by the use of brackets hanging on pre-existing floor-supporting pedestals. It can be installed above a dropped ceiling by the use of hangers clamped to the grid struts of the ceiling. The locking clips serve to electrically interconnect the channel members and the telescope members.

US Patent:

49508407, Aug 21, 1990

Filed:

Sep 16, 1985

Appl. No.:

6/776758

Inventors:

Maurice F. Zetena - West Redding CT

International Classification:

H02G 314

US Classification:

174 66

Abstract:

A flush type wall mounted coaxial connector assembly is provided for interconnection of coaxial cables. The assembly uses a recessed wall plate having at least one internal side which is at an obtuse angle to the surface and carrying a coaxial cable connector. As a result, the cable interconnection will be behind the wall surface and the extending coaxial cable will run substantially parallel to the wall surface and not intrude excessively into the room.

Wallboard Adaptor Bracket

US Patent:

52438023, Sep 14, 1993

Filed:

Jan 18, 1991

Appl. No.:

7/643450

Inventors:

Maurice F. Zetena - Bridgewater CT

International Classification:

E02D 3700

US Classification:

52514

Abstract:

A wallboard adaptor bracket formed of sheet metal defining a plate with a central opening therein, holes in the bracket for receiving retaining screws, the holes having been formed by coining the material to form an opening and to form a collar around the opening on one surface of the sheet metal. The retaining screw holes and collar are so dimensioned as to hold the retaining screws perpendicular to the bracket.

US Patent:

43302742, May 18, 1982

Filed:

Mar 30, 1981

Appl. No.:

6/248971

Inventors:

Joshua Friedman - Ridgefield CT
Maurice F. Zetena - West Redding CT

International Classification:

A61C 300

US Classification:

433 29

Abstract:

The lighting system comprises a lamp assembly including a conductive block having a plurality of longitudinal passageways extending from one end of the block adjacent the proximal end of the handpiece in a configuration matching the fluid transmitting conduit configuration extending from the handpiece and terminating at the opposite end of the block, means connecting said passageways at said opposite end to an air/water supply tubing, slidable means for removably coupling the lamp assembly to the handpiece, said block having a cavity for housing a miniature halogen lamp with the halogen lamp longitudinally seated in the cavity, means in said cavity for detachably engaging said lamp such that said lamp may be removed for replacement without disturbing the fluid interface between the block and the supply tubing, said lamp having a light transmitting end in close optical coupling with the proximal end of the handpiece, and wherein said slidable means includes an aperture in a predetermined location and means for engaging said block in a first position for enclosing the lamp assembly and in a second position for exposing the light transmitting end of the lamp through such aperture in the sliding means. In the second position the light generated by the bulb is directed into a fiber optic bundle removably attached to the handpiece.
