Abstract: A positioning system utilizes a shot pin to fix the position of a grooved pallet at stations in a production line. The pallet travels along the production line under the influence of advancing feed pins. When the pallet arrives at a station, the head of the shot pin is positively urged toward the groove in the pallet until the head locks the pallet in the desired position. Simultaneously, the feed pin disengages from the pallet. When work is completed at the manufacturing station, the head of the shot pin moves away from and releases the pallet. Simultaneously, the feed pin engages the pallet. The feed pins and the shot pin operate in tandem, by moving in-phase along parallel lines in the same direction to accomplish their individual functions. The feed pins and the shot pin can operate relatively quickly without applying unnecessary torque to the conveyor or the pallet.

Abstract: A pill dispensing system includes a shelving unit in array form that holds a number of bulk containers, each holding a bulk amount of a pill to be dispensed. A computer controlled robot removes a selected bulk container and places it on a counter that also dispenses pills. The robot has an arm with a free end portion that can grip a bulk container or a single pill bottle to be filled. The robot is computer controlled to retrieve an empty pill bottle, place it on a label printing and applying unit, then place it next to the counter/dispenser to receive the selected number of selected prescription pills, then place the filled, labeled bottle on a conveyor. In an alternate embodiment, pill bottles are dispensed from a dispenser that holds bottles on inclined plates and feeds them to a vertical dispensing channel. Gates prevent the flow of bottles from an inclined position until the plate above has been emptied.

Abstract: An optical symbol scanner assembly has an illumination attachment to facilitate detection and decoding bar code symbols that are printed or formed on mirror-finish surfaces. A hand-held scanner has an array of LEDs or laser diodes on its distal face that produces light to illuminate the symbol. The illumination attachment is mounted on the distal face of the scanner device. At a distal end of the illumination attachment is a diffusion-treated surface such that the illumination leaving the attachment appears as a bar or zone of diffuse light. This is reflected off the bar code, so that the mirror-finish areas appear as the bright or high portions of the symbol and the diffuse areas thereof appear as the dark or low portions. The attachment may be in the form of a block or plate of a clear plastic, or may be formed as a prism.

Abstract: A fluid level detection system includes an illumination source and a photodetector. The illumination source produces a beam at a fixed angle, which the photodetector is adapted to sense as it is reflected from the surface of a fluid. The photodetector varies in accord with the amount of the reflected beam that impinges on it. This amount, in turn, varies with the distance between the surface of the fluid, the illumination source and photodetector. The system can be used, for example, in automated pipetting applications in which it is important to ascertain the position of a pipette tip with respect to fluid contained within a body to provide safe and effective automatic processing of the fluid without the pipette tip contacting the body.

Abstract: A method and apparatus are provided for sputtering particles from a target as a film on a substrate. The target and substrate are maintained in a main housing in a first vacuum. The target is biased with a first negative voltage to effect a target bias. A plasma is produced in a cathode box spaced from the target, with the plasma being injected between the target and substrate to effect sputtering by bombarding the target with positive ions and liberating target particles for condensing on the substrate to form the film. The cathode box includes a cathode biased at a second negative voltage to effect a cathode bias, and a sputtering gas is supplied adjacent to the cathode for producing the plasma. Plasma production in the cathode box is decoupled from sputtering at the target for increasing sputtering yield and rate. And, the target may be contoured for focussing the sputtered particles on the substrate.

Rather than straight, the plurality may be circular and concentric. Rather than a plurality, the pattern may comprise a single straight line or circular light interface.

Abstract: A linear actuator divert switch, a limited angle motor driven divert switch and a limited angle motor driven cross-over switch are provided for sortation conveyors. In addition conveying members of inverted substantially "U" shaped having spaced relatively hollow legs spanned by a bridge that is either hollow or not are also provided for sortation conveyors. A package diverter is formed with a cavity extending therethrough to surround the conveying member and so as to carry a divert/guide pin and cam follower part of which is disposed in the space between the conveying member legs to provide a relatively high positioning for divert/guide pin and cam follower with respect to the conveying members. Special lands extend out from the walls of the cavity to cock each package diverter on its conveying members in the direction of conveyor movement. The divert/guide pins are formed with a generally football shaped cross-sectional configuration to facilitate passage thereof through the various switches.

Abstract: A batch thermal cycler for large numbers of biological or chemical samples uses n modules each in good thermal contact with the samples, but substantially isolated from one another, thermally and functionally. Each module carries samples on an upper sample plate. The module has a temperature sensor adjacent the samples, an electrical resistance heating element, and a circulating fluid heat exchanger for step cooling. Heating occurs at a point generally between the samples and the source of the cooling. The modules are individually replaceable. O-rings automatically seal fluid and electrical interfaces. An electrical controller has n simultaneous channels that provide closed loop control of the electrical power to each module. As a method, the invention includes at least one modular temperature zone where the temperature is sensed at a point adjacent the samples in that zone. The samples are heated adjacent the sample plate. Cooling is by a step change. The cooling overshoots a set lower temperature.
