Abstract: DIGITAL ELECTRONIC CONTROL AND SWITCHING ARRANGEMENT            ABSTRACT      A variable control, such as for a gain or frequency control, having a delay period and switching function at each end point, with status or level indication, is comprised of two simple switches and appropriate logic circuitry.          While a first switch is closed the gain would be reduced, at a predetermined rate, to a minimum point and held there for a brief interval during which a warning tone may be sounded.          If the switch is still closed at the end of the interval, an auxiliary function is enabled.  When a second switch is closed, the auxiliary function is disenabled and gain increases at the predetermined rate.  If the second switch is kept closed until maximum gain is reached and beyond, the warning tone is sounded for an interval, then a different function is enabled.  The unit will remain in that mode until the first switch is again closed.  Still another function may be enabled by simultaneous closing of both switches.  A visual status readout can be activated whenever either switch is closed.

Abstract: SEAT SUPPORT ASSEMBLY FOR A RECREATIONAL VEHICLE     Abstract of the Disclosure A seat supporting assembly for use in recreational vehicles such as motorcycles or the like and which includes pivotable arms between the vehicle frame and the seat for supporting the seat for generally linear vertical movement and further includes a spring assembly resiliently supporting the seat. The spring assembly can be pivoted to a different inclined position to adjust the resilient effect of the spring assembly and thereby compensate for riders of different weights.  A generally flat, telescoping strut is utilized for preventing relative rotation between supporting shafts, which shafts have seat supporting springs located between them. The strut also prevents the springs from buckling by preventing such rotation of their shafts. The generally flat, telescoping strut, which also serves as an upper stop means for the seat, eliminates the necessity for a conventional spring strut and permits the load to be all imposed on rearwardly located spring means.

Abstract: Abstract of the Disclosure A latch for a door of a substantially airtight solid-fuel stove, whose operation requires that before full opening of the stove door can be accomplished the door be positioned in a partially opened position while the latch is being manipulated.  A latch dog normally engages a wedge to hold the door fully closed, and a limit stop allows a first rotation of the latch mechanism to disengage the dog from the wedge but prevents rotation sufficient to allow the latch dog to clear the edge of the doorway opening.  A space defined between the wedge and the front of the stove permits the latch dog to pass between the wedge and the front of the stove during a second rotation of the latch mechanism, in the opposite direction, to a position allowing full opening of the stove door.  During this second motion of the latch mechanism the door is partially opened, allowing sufficient air to enter the combustion chamber to establish normal con-vective draft currents and prevent backpuffing and explosion of smoke and flame.

Granted: 1982-08-10
Abstract: ABSTRACT OF THE DISCLOSURE Oil sand is mixed with steam and water in a tumbler to produce a slurry.  The slurry is then transferred to the immersed portion of an aper-tured inclined surface in a water bath.  The inclined surface may be in the form of a rotating drum, a tilted rotating dish or an inclined moving endless conveyor belt.  The sand particles drop through the apertures and are collect-ed from the base of the bath and discarded.  The bitumen moves to the sub-merged portion of the oleophilic inclined surface and attempts to pass through the apertures, it touches the surface and adheres thereto. The adhering bitumen is collected when the coated surface emerges from the slurry.  The process gives a good recovery of a bitumen product which has acceptable quantities of solid and water contamination.  me temperature of separation, the need for reagents, and water requirements are reduced in comparison to the prior art.  The process can generally be used for separating oleophilic materials from hydrophilic materials.

Abstract: WIND POWER GENERATING SYSTEM            Abstract of the Disclosure Normally feathered propellers of a wind power generat-ing system unfeather in response to the actuation of a power cylinder that responds to actuating signals. Once operational the propellers generate power over a large range of wind velocities. A maximum power generation de-sign point signals a feather response of the propellers so that once the design point is reached no increase in power results, but the system still generates power. At wind speeds below this maximum point, propeller speed and power output optimize to preset values. The propellers drive a positive displacement pump that in turn drives a positive displacement motor of the swash plate type.          The displacement of the motor varies depending on the load on the system, with increasing displacement resulting in increasing propeller speeds, and the converse. In the event of dangerous but not clandestine problems developing in the system, a control circuit dumps hydraulic pressure from the unfeathering cylinder resulting in a predetermined, lower operating pressure produced by the pump. In the event that a problem of potentially clandestine consequence arises, the propeller unfeathering cylinder immediately unloads. Upon start up, a bypass around the motor is blocked applying a pressure across the motor. The motor drives the generator until the generator reaches a predetermined speed whereupon the generator is placed in circuit with a utility grid and permitted to motor up to synchronous speed.

Abstract: ABSTRACT OF THE DISCLOSURE      Flexible heating elements, for example, suitable for use in electric blankets and processes for their production are described.  The flexible heating element comprises at least two flexible electrical conductors spaced apart by a PTC material, an amorphous highly conductive rubber compatible with the PTC material and adhered to each conductor being interposed between the PTC material and each conductor whereby in use current passes from one conductor to another through the PTC material via the highly conductive rubber, the conductors being spaced sufficiently close to one another to ensure that when energised the PTC material heats substantially uniformly without exhibiting a significant temperature gradient between the conductors and that any abnormal temperature increase increases the temperature of all the PTC material between the conductors in the region of the abnormal temperature increase, the arrangement being such that in use the contact resistance between the conductors and the PTC material is reduced by the amorphous highly conductive rubber interposed therebetween.  The flexible heating element is produced by extruding the amorphous highly conductive rubber to cover each flexible electrical conductor and subsequently or simultaneously extruding the PTC material to cover the amorphous highly con-ductive rubber.
