Abstract: A switch controller for a dynamic switch (10) responds to commands from a using system to provide control signals to the dynamic switch (10) which causes the switch to establish and breakdown paths between sources and destinations in the using system. The controller includes a plurality of command registers which are temporarily assigned to a command source for receiving command signals, decoding said signals and providing control signals to the switch for establishing or breaking down a switch path. The controller may if desired provide an echo to a selected destination so that proper execution of commands may be ascertained. After the commands are completed the control register is released for reassignment to another command source while an established switch path remains intact. Thus, commands may be received from any source for controlling the switch.

Abstract: Hitherto, sulphur compounds have been removed from hydrocarbons by adsorption on activated carbon, silicates and zeolites. The use of a zeolite containing zinc and manganese is also known. However, all the existing processes are unsuitable for removing traces of sulphur from hydrocarbons. The novel process is thus intended to allow a deep desulphurisation of hydrocarbons. The deep desulphurisation of hydrocarbons is achieved by adsorption of the sulphur compounds on zeolites which contain copper, silver or zinc or mixtures thereof. Deep desulphurisation of hydrocarbons.

Abstract: ABSTRACT OF THE DISCLOSURE    A packaging material and a method of forming the packaging material  into a  flexible,  disposable  food container adapted to contain and maintain food in a fresh and sanitary condition, and   to ship,  display, heat and brown,  and serve the food is disclosed.  The method  includes   forming  patches  of  microwave interactive material on a web of plastic and laminating the web of plastic to one side of a web of structural stock material to form a composite web; the microwave interactive material is sandwiched between the web of plastic and the web of structural stock material. Sealant is applied to portions of the plastic layer in registry with the patches of microwave interactive material to seal ends of the composite web.   Printed graphics  are applied to portions  of  the  structural stock material layer in registry with the patches of microwave interactive material and the sealant.   The formed container is sufficiently flexible to contain food having curved and irregular surfaces  and to maximize contact of the food with the portion of the container housing the microwave interactive material. The container is  sealed so that portions  of  the composite web extend as fins beyond the sealed ends of the  food-containing portion of  the  container.    The container also is capable of receiving food before the food is frozen to prevent portions or parts of the food from falling out of their proper place in the  food packaging process.

Title: Apparatus and method for registration control of assembled components
Inventor: WEYENBERG STEVEN LAMBERT
IPC: G05B19/418
Filed: 1990-10-17
Granted: 2001-01-02
Abstract: Registration inspection of composite products during the fabrication of a series of such products is accomplished by making a two-dimensional image of a product and analyzing the image to determine the location of at least one component in the machine direction and the location of at least one component in the transverse direction. The thus determined locations are compared to the desired locations for the respective components in the composite article, and feedback control signals are utilized to adjust the fabrication process so that the components will be at the desired locations in subsequent products. When a component is outside of its acceptable position, the article can be removed from the fabrication line without further processing. The invention is particularly useful with fabrication lines for the production of absorbent articles, such as disposable diapers, incontinence devices, sanitary napkins, and the like.

Title: Time difference correction circuit for brightness and chrominance signals
Inventor: HONG SUNG HYUN
IPC: H04N9/89
Filed: 1991-02-15
Granted: 1995-08-22
Abstract: In accordance with one aspect of the invention, there is provided a time difference correction circuit for correcting  time  differences  between   luminance   and chrominance signals derived from a detected signal from a videotape.    The  circuit  includes  a  luminance  signal detecting circuit, a chrominance signal detecting circuit, a mixing circuit, a vertical synchronization circuit and a timing control circuit.   The luminance signal detection circuit extracts a  luminance signal  from the detected signal.  The chrominance signal detection circuit extracts a chrominance signal from the detected signal and includes a controllable delay line for delaying the chrominance signal by a controllable amount of time to produce a time difference  corrected  chrominance  signal.    The  mixing circuit mixes the luminance signal and the time difference corrected chrominance signal to produce a composite video output  signal.    The  vertical  synchronization  circuit detects a vertical synchronization signal in the luminance signal and delays the vertical synchronization signal to produce a delayed vertical synchronization signal.   The timing control circuit determines a time difference between the luminance and chrominance signals for each field in a horizontal interval, in response to the delayed vertical synchronization signal and outputs a control signal to the controllable delay line, the control signal corresponding to the time difference between the luminance signal and the chrominance signal.  The delay produced by the time delay is varied to correct the time difference.

Granted: 2000-01-25
Abstract: A plural component external mix air-assisted/airless spray gun has an airless tip from which resin is emitted in a fan-shaped spray and an injector nozzle for directing an unatomized stream of catalyst into the resin adjacent to the airless tip. The catalyst injector nozzle is built into an ear of an air cap and the air cap is keyed to the airless tip to guarantee the positional relationship between the injector nozzle and the airless tip. Injecting a stream of unatomized catalyst into the resin stream immediately downstream from the airless tip provides thorough mixing of the catalyst into the resin, increased utilization of the catalyst and decreased emissions of catalyst fumes.

Granted: 1998-11-24
Abstract: A processor is described for monitoring a sensor whose output signal follows a nonlinear curve in response to a  linear  change  in  a  monitored  phenomenon.   The processor  concerts  the  sensor  signal  to  a  linear output proportional or equal to the phenomenon being monitored.   The  processor includes  a memory  for storing a table which includes a starting data point value D on the curve,  a starting slope value S to another data point on the curve, a starting curvature value S' for a succession of the data points on the curve and a plurality of rate of change of curvature values S'' for the curve.  The values of S'' for a first region of the curve are calculated based on an initial output  signal  interval  between  data  point values.  The values of S'' for each succeeding region of the curve are based on increasing, by a preselected factor, the signal interval between data point values. The  processor  includes  a calculation  device  for computing repeated additions of the S,  S',  and S'' values.  An addition occurs when the sensor output signal  rises above a predetermined signal  interval value  between  data  points.   The  processor  also includes   a   controller   which   increases,   by   a preselected factor,  the predetermined sensor signal interval value each time the output signal enters a succeeding region of the curve.   Thus,  as the data points move up  the curve,  they become increasingly farther apart, but accuracy does not suffer as such data points  reside  on  the  more  regular  (steady curvature, for instance)  regions of the curve.  Data storage requirements are thus minimized.
