Title: Multi-station system to act upon footwear upper assemblies with transfer between stations thereof
Inventor: WILLIAMS GREGORY A
IPC: B25J5/02
Filed: 1987-11-19
Granted: 1992-10-06
Abstract: ABSTRACT         For use in a system that includes first and second machines to perform operations on a footwear upper assembly, a transfer machine that includes an activator arm assembly, and a gripper assembly rotatably and pivotally connected to one end of the activator arm assembly.  The gripper assembly includes a pair of fingers with a gripper jaw pivotally secured to each of the fingers.  The pair of fingers are movable toward and away from each other respectively to grasp and release the footwear upper assembly.  The pivotal attachment of the jaws permits the jaws to adjust to the irregular profile of the footwear upper assembly, a situation which is enhanced by the geometry of the gripper jaws which permits contact between the jaws at regions spaced longitudinally along the footwear upper assembly and by choosing a jaw material that is soft enough to deform, and hence provide larger contact area between the upper assembly and the jaws.

Abstract: The dispensing appliance customarily built in "pistol form" for double cartridges with plunger has a pressure medium-driven cylinder/piston unit with rams extending from the piston for forward drive of the plungers.  The problem here consists in that during the piston forward thrust the reaction forces from the plungers acting upon the two rams can be very different (different viscosities of the substances contained in the two cartridge cylinders and/or different cross-sections of the cartridge cylinders).  In order to prevent tilting or jamming of the piston, the invention provides in the cylinder space a rigid longitudinal guide between both cylinder end walls against which the piston is slidingly supported with a longitudinally extended guide bore.          The longitudinal guide can simultaneously reinforce the cylinder and further lead the pressure medium into the pressure chamber behind the piston by way of a longitudinal channel.  In this connection, rapid ventilation for the pressure chamber as well as control means for guiding the piston unit back to its starting position are described.  Further, retrieval means for the piston for ram relief after each forward thrust step as well as indicator elements for the cartridge fill-level are disclosed.

Title: Multi-channel modulated numerical frequency synthesizer
Inventor: IVES FRED H
IPC: G06F1/03
Filed: 1988-05-19
Granted: 1991-01-02
Abstract: Abstract A four-channel multifunction digital frequency synthesizer which uses direct numerical synthesis to generate one or more complex output signals having selectable frequency, phase offset, amplitude level and waveform is provided.  A waveform synthesizer digitally synthesizes precise sine, square, triangle, ramp, uniform and Gaussian noise and DC waveforms which can be selected for any of the four channels.  One of the four channels can be frequency, phase and amplitude modulated by the signals on the remaining three channels in any combination.  The four channels are time-multiplexed which allows the use of a single frequency synthesizer to realize four independent channels and a large number of support functions and capabilities in a high-density VLSI integrated circuit on a single chip.  The synthesizer system can provide up to four independent output signals which can be any one of the four channel signals, or any combination of the four channel signals summed to form a complex waveform signal.

Title: Menu selected application programs created from defined modules of code
Inventor: BONE WILLIAM K
IPC: G06Q40/02
Filed: 1988-06-03
Granted: 1995-06-13
Abstract: A system and method are disclosed for computer implementation of products wherein a designer examines the products desired by an institution planner and identifies functions ("components") collectively common thereto.  The designer proceeds to define component processes collectively common to such components and categorizes code for this purpose in groupings selectable (executable) by the planner upon system installation and subsequently changeable as desired. The component process selections of the planner are recorded and the system is thereby defined in its aspect which is accessible to the planner.  The designer works from such definitions of all components and component processes obtained from discussion with system planners prior to installations to define component subprocesses collectively common to the component processes and identifies combinations of component subprocesses in various sequences to realize component processes.  The code of each component subprocess is stored individually in "modules" for access by a computer to realize such combinations and reuse of such modules in this activity is effective to provide for uniformity in the practice of subcomponent processes from product to product.  The designer code for the component subprocess is inaccessible to the planner from a selection viewpoint and is viewed thusly as planner non-executable.

Granted: 1992-04-14
Abstract: Abstract of the Disclosure A signal separator performs an inter-line operation on a composite color video signal, thereby separating it into a luminance signal and a chrominance signal.  A scan converter converts each of the luminance signal and the chrominance signal into a sequential scan signal on the basis of the double-speed changing of the luminance signal and the chrominance signal.  A signal determina-tion circuit determines whether the composite color video signal is a standard signal or a non-standard signal.  A first clock producer produces first clocks to be phase-locked to a color subcarrier in accordance with the composite color digital video signal.  A second clock producer produces second clocks to be phase-locked to horizontal synchronizing signals in accordance with the composite color digital video signal.  A first controller causes the signal separator and the scan converter to operate in accordance with the first clocks when the signal determination circuit determines that the signal is a standard signal.  A second controller causes the signal separator to operate in accordance with the first clocks, causes the scan converter to operate in accordance with the second clocks, and con-verts a sampling rate of each of the luminance signal and the chrominance signal separated by the signal separator in accordance with the first clocks into a rate of the second clocks when the signal determination circuit determines that the signal is a non-standard signal.

Abstract: ABSTRACT OF THE SPECIFICATION         In the method for the production of an aromate concentrate suitable for use as blending component for carbuerator fuel, feed hydrocarbon mixtures having boiling ranges substantially between 40 and 170°C, are subjected, without any previous separation into individual fractions, to an extractive distillation employing N-substituted morpholine, substituents of which display no more than seven C-atoms, as selective solvent.  Herewith, the lower boiling non-aromates with a boiling range up to about 105°C, practically completely, and most of the higher boiling non-aromates with a boiling range between about 105 and 160°C, are recovered as raffinate, whereas the aromates, which are to be employed in whole or in part as blending component, come down in the extract of the extractive distillation.  In order to separate heavy aromates from solvent, a partial stream of the circulating solvent is mixed with water, and the heavy aromates are separated as a light phase from the solvent-water mixture.  The solvent-water mixture is then separated into its components, which are re-utilized.

Abstract: A B S T R A C T             Bar Code Laser Scanner Arrangement for a Cashier Stand The invention provides an arrangement for scanning bar codes applied to articles, such as UPC or EAN codes of goods in a supermarket cashier stand. A laser scanner is provided with a window through which the scanning rays exit before they impinge on a scanning area (11). The laser scanner (4) is arranged at the side of the transport flow and with its window (5) tilted to the rear and being above the transport plane (6). The different rays (20 - 23, 25 - 25c, 26 - 26c, 30a - 30f, 31a - 31f) of the cluster of scanning rays of scanner (4) are oriented such that they are concen-trated and focussed mainly on the scanning area (11) in front of the window (5), that they do not leave the transport plane (6) immediately opposite the window, and that generally a ray-free area is formed there where at least head and chest of an operating cashier (1) that sits opposite to the scanner (4) with its window (5), is situated. By this arrangement, in which for example as laser scanner an IBM 3687 model 002 laser scanner can be used, it is made sure that the operating cashier sitting in front of the cash stand and essentially opposite of the scanning window is not struck by any ray of the cluster of scanning rays. This improves the acceptance of such an arrangement within the market place considerably.

Abstract: OPTICAL SENSOR FOR THE DETECTION OF ICE   FORMATION AND OTHER CHEMICAL SPECIES                 Abstract of the Disclosure An ice sensor for the remote rapid indication of ice formation or the presence of  ice  is  a  fiber optic "switch", activated by ice but not by water, and based on the difference in optical properties between water and ice.  The approach is to construct a "fiber optic" which itself is the ice sensor.  The fiber optic sensor (FOS) is designed so that no light is transmitted when water is present but as soon as ice begins to form, light is  relayed.   Thus  ice  switches  on the  light.   In addition, limited quantitative information can be made available on the rate of ice formation.  Alternatively the  sensor  can  be  formed  of  another  type  optical waveguide instead of an optical fiber.  The ice sensor is formed by placing spaced stripes of a clad material on a fiber optic core,  or other waveguide structure, where the clad has a refractive index close to ice and the core has an index greater than the clad but les than water.  It is best to index match the core to the clad for optimal transmission when ice forms in the gaps between the clad stripes.  This device can be constructed using a variety of sturdy materials.   It should be constructed using a variety of sturdy materials.   It should be particularly suitable for applications where long-term exposure to adverse weather conditions are expected.   The advantages of the ice sensor include: specific,  sensitive, real-time response, small,  light weight, inexpensive, requires no line-of-sight, EMI     immune, rugged and flexible.  The instrumentation needed to operate the ice FOS is simple, small, lightweight, inexpensive, easy to operate, battery powered - optional, rugged,   reliable   and  amenable  to  telemetry  of information.   A fiber optic core or other waveguide structure with spaced clad stripes can also be designed to  detect  other  chemical  species,  or  a  particular concentration of a chemical species, or phase transitions of other species by selecting a clad with a refractive index close to the material to be detected.
