Title: Method and apparatus for transferring relatively flat objects
Inventor: COOK STEVEN T
IPC: B21D51/44
Filed: 1988-02-26
Granted: 1990-12-11
Abstract: Abstract of the Disclosure An apparatus for transferring a relatively flat object from a work station along a transfer path includes an upper tooling within the work station for locating the object in a ready position by causing an upper surface of the object to adhere to the tooling.  The object is thus unsupported along its lower surface.  A manifold forming an orifice is located adjacent to and directed toward the ready position, and is connected to a source of compressed gas.  A valve initiates and discontinues flow of pressurized gas through the orifice.  A control system controls the valve to direct a stream of pressurized gas through the orifice when an object is located in the ready position, thereby causing the transfer of the object in free flight from the work station.

Granted: 1993-07-13
Abstract: ABSTRACT OF THE DISCLOSURE           New and improved apparatus and method for the separation of immiscible liquids are provided, and comprise the use of separator means having a surface which is preferentially "wettable" by one of the liquids to the substantial exclusion of another of the liquids. In use, the liquids are flowed from a common liquids source onto said surface with the one liquid being sorbed thereby to the substantial exclusion of the other liquid to thus substantially separate the liquids.  The separator means surface may be maintained essentially level to retain the substantially separated liquid thereon, or may be inclined to result in the flow of the same therefrom  under the influence of the force of gravity. Alternatively, the separator means may be made of a liquid-permeable material to permit the flow of the substantially separated liquid therethrough and therefrom under the influence of the force of gravity.  The apparatus and method are particularly adapted to the substantial separation of aqueous sample liquids from hydrophobic isolation liquids which encapsulate the same; and are readily combinable with a sample liquid reaction device to effectively combine the sample liquid separation and reaction operations.  The material of the separator means may be inherently hydrophobic, or may be rendered super-hydrophobic by the surface coating thereof with a super-hydrophobic coating material.

Title: Fault-tolerant output circuits

Granted: 1993-03-30
Abstract: FAULT-TOLERANT OUTPUT CIRCUITS                 ABSTRACT OF THE DISCLOSURE          Circuit modules for providing digital or analog outputs from computational devices in such a manner that the components of the output circuit modules are tolerant of malfunctions in one or more of the components.  In the digital output embodiment of the invention,  output signals are independently derived using two voting circuits and are then applied to two switches connected in series to provide a fail-safe condition for most types of failure of the switches or the voting circuits. Two identical modules provide the ability to faithfully follow commanded on or off signals in all but a statistically small number of situations, and permit convenient replacement of a defective module without affecting output through the other module.  In an analog output module, two independent voting circuits provide voted digital outputs to separate digital-to-analog converters, the outputs of which are compared to generate a validity signal that is used to control an output switch. The validity signal for the module can be combined logically with the switch status of another identical module, to determine which of the modules should be activated by closure of its output switch.  An inactive module can be removed and re-placed without affecting the integrity of the analog output signals.
