US Classification:
2502521, 250361 R, 250362
Abstract:
An optic module verification device for normalizing between X photon counters, including a verification tray with X verification wells and a modular photon emitter in each verification well. Each photon emitter includes a spring, a Beta source disk, a scintillator disk adjacent the Beta source disk, and a neutral density filter over the scintillator disk, all of which are encapsulated in a cylindrical chamber with the filter adjacent an opening on one end of the chamber and the spring biasing the Beta source disk and the scintillator disk toward the opening. The device is periodically used for normalization, and may be updated when emitted photons fall below a desired level by replacing the scintillator disk and then determining a new normalized reference values for each photon emitter.

US Classification:
2502521, 250361, 2504931
Abstract:
An example optic module verification device for use in periodic normalization of a testing machine used to test samples in wells is disclosed. The example testing machine includes a plurality of photon counters that each count photons emitted from different wells. The example verification device includes a plurality of verification wells located so as to each be associated with one of the photon counters when used in the testing machine. The example device also includes a photon emitter in each verification well, each photon emitter including a Csource, a scintillator adjacent the Csource, and a filter over the scintillator. The example photon emitters each have a determined initial base value for emitted photons, and each photon emitter is positioned in its verification well to emit photons through the filter to the associated photon counter when used in the testing machine.

International Classification:
B08B 3/12
US Classification:
134 1
Abstract:
A method for cleaning deposits of particulate material from the tip of a nozzle of a dispensing apparatus, such as, for example, the tip of the nozzle of a liquid reagent dispensing apparatus. The method involves the use of a multiple excitation signal waveform to cavitate and agitate the cleaning medium in which the tip of the nozzle is suspended. Multiple excitation refers to a method of excitation that uses waves of alternating polarity; multiple excitation may involve excitation at a plurality of frequencies in sequence, at a plurality of amplitudes in sequence, at a plurality of waveforms in sequence, combinations of the aforementioned frequencies, amplitudes, and waveforms. The invention also provides an apparatus incorporating electrical and mechanical components, along with appropriate software, sufficient to perform the method described herein.

VHC, Ltd. - West Palm Beach FL
International Classification:
B65G 2500
US Classification:
19846801
Abstract:
An article transfer mechanism for use with an I. S. glassware forming machine includes a pusher arm having fingers for engaging a number of glassware articles formed by the I. S. machine, the pusher arm being movable between a first position to engage the glassware at the dead plate and a second position at which the glassware is transferred to a take-away conveyor. A stepping motor is provided for moving the pusher arm between the first and second positions according to a velocity profile. A microcontroller and electronic circuitry associated with each section of the I. S. machine determine a new current position of the pusher arm as the arm moves according to the velocity profile. The microcontroller performs calculations at each new current position of the pusher arm according to an equation contained in a memory to determine a new velocity for the pusher ar at the new current position of the arm as a function of the current position, such that each new velocity at each current position defines the velocity profile. The microcontroller performs the calculations "on-the-fly" as the pusher arm is moving through its 90. degree.
