Title: Closed loop magnetic brush development system
Inventor: BHAGAT GOPAL C
IPC: G03G15/00
Filed: 1991-11-21
Abstract: ABSTRACT          CLOSED LOOP MAGNETIC BRUSH DEVELOPMENT SYSTEM     A printing machine,  such as a copier or a printer,  is provided with an electrophotographic engine cartridge including a  toner  castridge,  a  rotatable  photoconductor drum,  and a specially  designed  magnetic  brush  development  module.  The development module utilizes a rotating magnetic roller, disposed in a developer sump,  to transport a toner carrier delveloper material toward a side surface portion of the rotating drum onto which  the  toner  position  of  the  transported  developer  is electrically transferred.  The development module is operated in a unique closed loop fashion by the action of a specially designed blade  member which strips  away the toner-depleted developer from the roller and causes it to enter a recycling well.   The depleted developer is transferred from the recycling well into the developer sump wherein it is mixed with toner entering the sump from the toner cartridge, and then re-applied, in the form of reconstituted developer, to the magnetic roller for subsequent toner transfer to the rotating drum.

Title: Method and apparatus for forming a permanent foam coating by atomization onto a substrate
Inventor: SAIDMAN LAURENCE B
IPC: A23P30/40
Filed: 1990-08-03
Abstract: A method of atomizing a high solids viscous composition (21) onto a substrate (27) and foaming the composition comprising mixing a coating composition with a gas foaming agent under elevated pressure and temperature. The coating composition (21) is airlessly atomized and projected onto a substrate (27).

Title: Reversible stoma-adjustable gastric band
Inventor: KUZMAK LUBOMYR I
IPC: A61F5/00
Filed: 1991-07-29
Abstract: A reversible gastric banding device for creating a stoma opening in the stomach (51) for restricting food intake into the lower digestive portion of the stomach (51). The band (20) is operatively placed to encircle the stomach (51). Once in position, it is held securely with sutures (61) on the outside of the stomach (51) thereby prohibiting the encircled stoma opening from expanding. If it becomes necessary or desirable to remove the gastric band (20), a remotely actuated releasing portion permits the removal of the gastric band (20) without major surgery. In one embodiment, the banding device is conveniently removed by means of a retractable blade (25) within the band (20) which blade (25), when retracted by remote activation, severs the retaining sutures (61) and frees the band (20) for removal. Additionally the most preferred embodiment of the device includes a flexible substantially non-extensible band (12) portion having an expandable, balloon-like section (15) that is in fluid communication with a remote injection site.

Title: Air bag device for assistant driver's seat
Inventor: KOKEGUCHI AKIRA
IPC: B60R21/20
Filed: 1992-07-16
Abstract: Abstract of the Disclosure An air bag device for an assistant driver's seat comprises: a container having an opening for expanding an air bag on the front surface and intake ports for inletting air on the side surfaces; a lid covering the opening; valve plates provided in the container for closing the intake ports by being overlapped on the side surfaces and opening the intake ports by being separated therefrom; an air bag accommodated in the container in the folded state; a gas generator fixed on the rear surface portion of the container facing to the opening; first gas  ejecting holes for ejecting  gas toward the front surface of the container and second gas  ejecting holes for  ejecting gas toward the valve plates; and sealing means attached on the gas generator for sealing the first and second ejecting holes.  The sealing means opens only at first gas ejecting  hole portions when ejected gas pressure in the gas generator exceeds first predetermined pressure thereby allowing the gas to pass through the first gas ejecting holes to be  ejected toward the front surface of the container.  The sealing means opens further at the second gas ejecting  hole portions when ejected gas pressure exceeds a second gas pressure higher than the first gas pressure thereby allowing the gas to pass through the second gas  ejecting holes to be ejected  toward the valve plates.          When only the first ejecting holes open, the valve plates are pushed with the atmospheric air thus allowing the air to flow in the container through the intake ports.      When the first and second ejecting holes open,      gas passing through the second ejecting holes causes the valve plates to move near the intake ports thereby reducing the amount of the air flowing in the container.

Title: Gps tracking system
Inventor: BROWN ALISON K
IPC: G01S5/00
Filed: 1992-11-19
Abstract: A low cost tracking system employing satellites of the global positioning system (GPS) is suitable for applications involving radiosondes, sonobuoys, and other objects. The tracking system includes a sensor mounted on each object which digitally samples the GPS satellite signals and records them in a data buffer. The digital samples are then transmitted, at a rate lower than that at which the GPS satellite signals were sampled, over a data telemetry link, interleaved with other telemetry data from the object. The GPS data is processed in a data processing workstation where the position and velocity of the sensor, at the time the data was sampled, is computed. The data buffer in the sensor is periodically refreshed, and the workstation periodically computes the new position and velocity of the sensor. Differential corrections are also provided at the workstation to aid in signal acquisition and to increase the precision of the position fix.
