Title: Clamping sleeve for pipes
Inventor: GEHRING MANFRED
IPC: F16L/
Filed: 1985-11-13
Granted: 1991-07-16
Abstract: ABSTRACT OF THE DISCLOSURE     In a coupling sleeve for pipes, which consists of a rubber-elastic sealing ring and a clamping ring encircling the sealing ring, on the ends of which clamping ring are attached parts having clamping elements directed outward and located opposite one another, the gap between the clamping elements is bridged by a sheet-metal part which sits against the outer side of the clamping ring and, like the clamping ring itself also has radially inwardly directed flanges at side edges and, at the overlapping point with the end of the clamping ring, fits between the flanges of the clamping ring.          The sheet-metal part is formed by an end portion of the clamping ring which has a longitudinal slot which extends up to an end of the end portion and, in turn opens at its inner end into a transverse slot.   It is an advantage of the invention that by bending the sections separated by the longitudinal gap a certain sealing contact of the metal end sections of the clamping sleeve against each other is possible.   It is advantageous especially if the pipes to be linked have different diameters.

Granted: 1990-10-16
Abstract: ABSTRACT    The invention is a process and a product of the process  for  preparing  a  baked  snack  food  from a composition containing at least one ingredients having starch.  The ingredient having starch and the water comprises substantially all of the ingredients of the composition.    The  method   involves   steaming  the composition to form a dough-like consistency.   In the most  preferred  embodiments  of  the  invention  the ingredient including starch is either a corn or a potato ingredient.    The steaming is conducted until the composition obtains a temperature of at least 160°F and preferably 200°F.   The composition is held at this temperature  for about 2 to about  6 minutes.   The composition is then machined, formed into pieces, and baked  in  a  conventional  oven.    During  baking  the exterior layer of the dough cooks rapidly and traps steam in the interior portion of the dough.   Blisters and curls result in the final product that impart a chip-like  appearance  to  the  final  product.     An alternative embodiment includes applying a spray oil to the pieces before baking to obtain a final product having a flat cracker-like appearance.

Title: Vibratory screening apparatus
Inventor: BAILEY MARSHALL G
IPC: B07B1/48
Filed: 1986-06-12
Granted: 1992-07-07
Abstract: Abstract A basket of vibratory screening apparatus has an inflatable hose positioned to overlie a part of a screen unit mounted in the basket.  Inflation of the hose causes it to press against a frame of the screen unit clamping it against a support of the basket 101.  The hose is at least partially flattened on its underside when inflated and a resilient ring surrounds the hose to bear against the flattened underside.  During deflation of the hose the ring assists deflation and flattening of the hose.

Title: Fluid flow control apparatus for a power steering system
Inventor: MILLER LAURENCE L
IPC: B62D6/02
Filed: 1987-07-06
Granted: 1992-03-17
Abstract: Abstract A power steering system includes a hydraulic pump and a hydraulic steering mechanism.  A flow control orifice passes fluid from the pump to the steering mechanism and generates a hydraulic control signal proportional to the fluid flow rate therethrough.  A flow control valve is connected between the pump to bypass fluid away from the steering mechanism in response to the hydraulic control signal.  A solenoid operated valve is located in a pilot fluid circuit between the pump and the flow control orifice to vary the hydraulic control signal in response to an electrical control signal.  The electrical control signal is a pulse width modulated signal having a duty cycle proportional to vehicle speed.  Maximum power assist occurs when vehicle speed is below a predetermined value and decreases with increasing vehicle speed above the predetermined value.

Title: Fuel tank for an off-road vehicle
Inventor: SMOLA ROBERT J
IPC: B60K15/00
Filed: 1987-07-13
Granted: 1991-03-05
Abstract: FUEL TANK FOR AN OFF-ROAD VEHICLE    Abstract of the Disclosure A fuel tank construction having a non-vented filler neck and cap, a shut-off valve sealed to the tank by a fluorocarbon bushing, resistant to both alcohol and sunlight, is positioned in the tank such that, upon bushing failure, no more than ten percent of a full fuel tank would leak therefrom, at least one protruberance having an air pocket formed therein and a vent system connected to the protruberance communicating between the air pocket and the atmosphere.  The venting system consists of a long plastic tube attached to the vent and routed over the upper surface of the tank having the open end positioned such that any fuel which might discharge through the open end is directed away from the tank and any vehicle it might be attached to. Additionally, a low fuel sensor may also be incorporated and connected to the tank by a similar bushing as that used to connect the shut-off valve.  The low fuel sensor utilizes a casing having pin holes surrounding a thermistor.  This sensor arrangement reduces the sensitivity of the sensor to sloshing fuel.  The shut-off valve and the low fuel sensor are connected to the tank such that no more than ten percent of a full tank is at or above the two bushing connections.

Title: Satellite communications system having multiple downlink beams powered by pooled transmitters
Inventor: ROSEN HAROLD A
IPC: H01Q25/00

Granted: 1991-04-09
Abstract: SATELLITE COMMUNICATIONS SYSTEM HAVING MULTIPLE DOWNLINK BEAMS POWERED BY POOLED TRANSMITTERS               ABSTRACT OF THE DISCLOSURE                A satellite communications system employs separate subsystems for providing broadcast and point-to-point two-way communications using the same assigned frequency band. The broadcast and point-to-point subsystems employ an integrated satellite antenna system which uses a common reflector (12). The point-to-point subsystem achieves increased communication capacity through the reuse of the assigned frequency band over multiple, contiguous zone (32, 34, 36 38) covering the area of the earth to be serviced. Small aperture terminals in the zones are serviced by a plurality of high gain downlink fan beams (29) steered in the east-west direction by frequency address. A special beam-forming network (98) provides in conjunction with an array antenna (20) the multiple zone frequency address function. The satellite (10) employs a filter interconnection matrix (90) for connecting earth terminals in different zones in a manner which permits multiple reuse of the entire band of assigned frequencies. A single pool of solid state transmitters allows rain disadvantaged users to be assigned higher than normal power at minimum cost. The intermodulation products of the transmitters are geographically dispersed.
