Title: Tire tread compounds based on vinyl polybutadiene
Inventor: ODAR JOSEPH
IPC: C08K3/04
Filed: 1987-08-21
Granted: 1992-02-18
Abstract: Abstract of the Disclosure Rubber compositions for use in tire tread compounds comprise co- vulcanizable blends of high 1,2 (vinyl) content polybutadiene of high molecular weight and high cis-1,4-poly-butadiene of high molecular weight.  The blends show a high degree of homogeneity, so that they act effectively as a single polymer, and exhibit a substantial absence of a glass transition temperature.  The relative amounts of the two polymers are such as to obtain a 1,2-group content in the blend of from 35-65 percent.  The blend may be compounded with conventional compounding ingredients for curing purposes, and optionally with additional polymers such as natural rubber and/or SBR.          The vulcanizates of the compositions exhibit a superior and unexpected balance of resilience, traction and wear properties.

Title: Self-adjusting control valve for elevators
Inventor: LAWRENCE WILLAU A P
IPC: B66B1/04
Filed: 1987-10-13
Granted: 1990-09-25
Abstract: SELF-ADJUSTING CONTROL VALVE FOR ELEVATORS ABSTRACT OF THE DISCLOSURE The invention discloses an automated hydraulic valve, for use in an elevator propulsion system. The elevator includes a car which is powered by a piston which moves within a cylinder. The automated valve controls the flow of hydraulic fluid into and out of the cylin-der. The valve insures that the acceleration and deceleration of the elevator car will be uniform, and that the acceleration or decelera-tion will occur over a constant, predetermined interval, regardless of the load in the car. The control valve allows fluid to flow from a reservoir, and into the cylinder or back to the reservoir, with vary-ing rates of flow. When fluid is directed into the cylinder, the elevator ascends. When fluid is allowed out of the cylinder, the elevator descends. The operation of the control valve is governed by a bypass piston assembly which is moved in response to the sensed pressure in the cylinder and the pressure in the valve. The rate at which the bypass piston assembly is moved is precisely controlled, preferably by a microprocessor. The rate of movement of the bypass piston assembly compensates for changes in the weight of the elevator car. The invention therefore also includes a method of controlling a hydraulic valve for an elevator, which method insures that the opera-tion of the elevator will be substantially independent of changing load conditions.

Title: Locking apparatus for floor mount connector
Inventor: MUELLER WOLFGANG
IPC: A61G13/10
Filed: 1988-04-07
Granted: 1992-02-04
Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for blocking the release of a surgical table from engagement with a floor bracket is provided.  In a surgical table having a foot lever which actuates a bar to cause the release of connecting means from a tongue of a floor bracket, a vertical pin is provided on the bar.  A base plate having a slot therein is provided on the lower portion of the surgical table adjacent to the pin.  A blocking plunger of a first pulling solenoid may be extended across the slot to block the movement of the pin to prevent the displacement of the bar and the release of the connecting means from the tongue.  The extension of the blocking plunger is caused by the retraction of an extension plunger of a second solenoid, which extension plunger is parallel to but disposed above the blocking plunger and is connected to the blocking plunger by a connecting block.  The extension of the blocking plunger causes a cam surface on the connecting block to engage a cam follower to actuate a microswitch which produces a signal indicating the blocking of the pin.  The blocking plunger may be retracted from its blocking position by being retracted by the first solenoid to free the pin and allow release of the surgical table from the floor bracket.

Title: Traffic monitoring device
Inventor: LOEVEN HANS-GERD
IPC: G08G1/054
Filed: 1988-08-25
Granted: 1993-04-20
Abstract: Abstract A  traffic  monitoring  device   mounted   in  a  moving monitoring  vehicle  comprises   a   radar   device  for measuring  the  relative  speed  of   a  vehicle  to  be detected  with  respect to the speed of  the  monitoring vehicle.  A  speedometer  measures   the  speed  of  the monitoring  vehicle.  By means of a releasing mechanism automatically  triggered  at adjustable limit speeds, a camera  is  released and the vehicle to be  detected  is photographed.  The  relative speed of the vehicle to be detected  and  the  speed of the monitoring  device  are added  in summing means. The sum then corresponds to the absolute  speed  of  the  vehicle to  be  detected.  The camera  is not released dependent on the relative  speed but  on the  absolute  speed  of the  vehicle  to be  detected. Thereby, all vehicles exceeding an allowed speed  are detected without taking an unnecessary number of pictures.

Title: Out-of-balance control for laundry machine
Inventor: WILLIAMSON GEORGE
IPC: D06F33/48
Filed: 1988-10-06
Granted: 1992-12-22
Abstract: ABSTRACT     An  out-of-balance  control for a laundry machine is  described.  The input to the control is a current signal  which  is  proportionate to the current drawn by  a  motor  which  rotates  a  perforated drum into which  fabric  goods  are  loaded.   When the drum is accelerated  from a relatively low speed, employed to a  washing  cycle, to a somewhat higher, distribution speed,  the  input  to  the  control is a "real time" signal  which reflects variations in torque  required to   rotate  the  drum.    The  magnitude  of  these variations  is  proportional  to load unbalance which can  cause  radial  displacement of the drum, machine vibration and  damage  to  its components.  The real time  signal  is  averaged.  A differential amplifier then  subtracts  the  "average" signal from the "real time"  signal, providing an "unbalance torque" signal of   alternating   polarity.    When the  "unbalance torque"  signal exceeds a given magnitude, reflecting the  maximum  permissible  centrifugal  force  to  be generated  by  load unbalance, an "unbalance control" signal  is  generated.    The  main  control  of  the machine  is  responsive to this last signal to reduce the rotational speed of the drum.

Title: Routing of network traffic
Inventor: KRISHNAN KOMANDUR R
IPC: H04M3/00
Filed: 1988-12-08
Granted: 1992-11-24
Abstract: Abstract of the Disclosure A process is disclosed for routing service requests through a network comprising nodes interconnected with links.  The network is also arranged so that each node may communicate with each of the other nodes.  At preselected time intervals, sets of routes through the network are generated in response to the network configuration and traffic information.  Also, at predetermined time intervals, occupancy factors are computed as determined by the network configuration and in response to traffic information.  These occupancy factors are proportional to unassociated occupancy factors and allocation factors associated with calls of the various node-pairs, each of these latter factors is derived from a nominal routing scheme in which a call of the corresponding node-pair is treated as lost only if it is blocked on all of its permitted routes.  Upon a request for service, the occupancy factors corresponding to the busy-idle status of the links are used to compute an occupancy value associated with each of the routes.  Each route is converted to a candidate route based on traffic load at the initiation of the service request.  The minimum occupancy value for each set of routes is selected as the candidate route for bridging a given node pair.  If this minimum value is less than a preselected threshold, the traffic is routed over this candidate route, thereby satisfying the service request.  Otherwise, the request is denied.
