Patent NO-162988-C (NO)
Inventor: GRAUEL CHRISTOPH
IPC: H04B7/26
Filed: 1983-12-14
Abstract: A cellular radio system in which the mobile radio stations in the zone of any base radio station assign themselves to the control channels allocated to that base station so as to evenly spread the volume of traffic over such control channels. The base station transmits on each control channel a channel group code signifying the range of group code numbers allocated to that particular control channel. Each mobile station stores its identifying group code number, scans the group code numbers of all control channels, and assigns itself to the control channel having a channel group code which includes its group code number. The spread of traffic over the various control channels can be changed by the base radio station simply by changing the channel group codes of the various control channels, without addressing specific commands to the mobile radio station.

Title: Video sidepanel noise reduction with amplitude compression and predictive expansion
Inventor: KOSLOV JOSHUA LAWRENCE
IPC: H04N7/32
Filed: 1989-10-31
Granted: 1999-12-28
Abstract: A video signal processing system employs an amplitude compander for reducing the effects of transmission noise. The compander includes a transmitter nonlinear amplitude compressor for amplifying small signals and compressing large signals. A receiver includes an amplitude expander with an inverse transfer function.      The nonlinear compressor generates out-of-band frequencies which are removed by a transmitter output filter, producing signal distortion. To compensate for such distortion, the transmitter duplicates certain receiver processing circuits, including the receiver amplitude expander and a filter for generating a prediction signal. The prediction signal is subtracted from the transmitter input video signal before the video signal is amplitude compressed at the transmitter, producing an error signal which is transmitted. The error signal is small if the prediction is good, whereby noise reduction results from compressor gain at the transmitter.

Title: Drainage valve having a flexible flap with an edge taper
Inventor: PROULX SERGE LIONEL
IPC: F16K15/18
Filed: 1990-08-08
Granted: 1995-10-24
Abstract: A valve is installed into an underground conduit to control drainage of water through that conduit.    The  drainage  control  valve  includes  a perforated plate across the conduit.  The latter plate is formed with a peripheral groove rectangular in cross section and a hollow tube made of flexible material is inserted into this groove to seal the joint between the plate and the inner surface of the conduit.   A flap also made of flexible material is applied against the upstream surface of the plate and is  formed  with  a  peripheral  edge  taper  whereby pressure applied on the flap by water upstream of the drainage valve  forces the edge taper against the upstream plate surface to form a sealed joint between these flap and plate.  The upper portion of the flap is attached to the upper portion of the plate through screw and nut assemblies.  These assemblies traverse rigid washers inserted in respective holes made in the flap.  The flap is slightly thicker than the washers for preventing excessive crushing of the  flexible material  upon  tightening  of  the  screw  and  nut assemblies while ensuring water imperviousness.   An elongated member integral with the flap has a free end formed with a hole to attach a cord enabling lifting of the lower portion of the flap to thereby drain water through the perforated plate.

Title: Torque limiting coupling
Inventor: KAMPF KLAUS
IPC: F16D7/04
Filed: 1992-11-09
Granted: 1998-12-08
Abstract: A torque limiting coupling (5) has a plurality of slide-like driving members (19) circumferentially and movably distributed in a coupling hub (10).  The unit is rotatably accommodated in a coupling sleeve (7).   The driving members (19), with their torque transmitting faces (25) at their heads, are pushed by a spring  assembly  (38, 39)  and  switching  cams  (32)  into correspondingly designed recesses (22) of the coupling sleeve (7).  The pressure springs (38, 39) and the switching faces (30, 31)  of  the  driving  members  (19)  as  well  as  the  torque transmitting face (25) are arranged so as to extend in the same direction.  Thus, the springs (38, 39), during the transmission of torque by the coupling sleeve (7), subject the driving members (19) to a moment which acts against the tilting moment resulting from the transmission of torque.  This results in an improved wear and switching behavior.

Title: Bidirectional valved catheter
Inventor: FENTON PAUL V JR
IPC: A61M1/00
Filed: 1992-05-11
Granted: 1995-10-24
Abstract: A valved catheter (10) having an elongated, flexible tubular element (18) defining a lumen (20) extending along an axis substantially parallel to the central axis (A) of said tubular element, and a bidirectional check valve assembly (12) near its distal end (16) which controls fluid flow in the tubular element. The valve assembly includes an aspiration valve (24) offset from the tip of the distal end of the tubular element and an infusion valve (26) formed at the tip of the distal end of the element. The aspira-tion valve is generally defined by one or more ports (24', 24") in the tubular element and a sleeve (30) within the tubular element underlying the ports, where the sleeve normally closes the ports. The aspiration valve (24) permits fluid flow from the patient's bloodstream into the tubular element (18) when the static fluid pressure inside the tubular element distal end (16) is lower than the static fluid pressure outside the aspiration valve by an amount sufficient to displace the sleeve (30) to allow fluid flow through the ports. The infusion valve (26) includes a throat (42) formed in the tubular element distal end (16) which tapers down to a mouth (44) formed by jaws (or "lips") (48, 48') at the tip of the tubular element. The mouth (44) is essentially closed to fluid in-flow from the patient into the tubular element and normally closed to fluid outflow from the tubular element into the patient. The infusion valve (26) permits fluid infusion into the patient's bloodstream when the static fluid pressure inside of the tubular ele-ment distal end (16) is higher than the static fluid pressure outside of the infusion valve (26) by an amount sufficient to force the mouth (44) open. A bidirectionally valved mutiple lumen catheter (10') is also disclosed.

Abstract: A motion control system for hydraulically operated lifting devices. The system provides for the dynamic weighing of a loaded container by controllably directing hydraulic flow through a bypass chamber (51) of a two-way valve (42). An analog output signal is generated by a hydraulic pressure transducer (53) fluidly communicating with the two-way valve or by a tensiometer (24) mounted on the arms of the lifting device (14). The two-way valve (42) further provides a second bypass chamber (54) which receives fluid under gravity from the lift circuit line (40) of the hydraulic cylinder (18) for controllably lowering the lifting device (14). The pressure transducer (53) or tensiometer (24) generate an analog signal proportionate to the weight being lowered and whereby the hydraulic fluid is returned to the reservoir of the hydraulic system independently and downstream of the main operating valve (33).
