Abstract: Kobelt 28 C.W     FLUID ACTUATED POSITIONER     A fluid actuated positioner for producing a mechanical output signal proportional to a fluid input signal.  Input signal acts on input rod of input cylinder to control a main valve which controls flow between chambers of a hydraulic power cylinder.  Power cylinder has output piston rod connected to device to be controlled, and fluid forces on output rod are determined by pressure differences across faces of output piston, which differences are determined by amount of metering of main valve.  Valve can be simple clearance passage maintained open to permit steady flow therethrough in non-changing signal, or can be spool valve which stops flow during non-changing. Both devices do not require exceptionally close toler-ance manufacture, and creep problems are reduced.

Abstract: ABSTRACT OF THE DISCLOSURE   Insert and assemble editing of video signals are carried out using a VTR having helically scanning rotary record/playback heads. Following the recording of a first video signal in slant tracks on the tape, the tape is stopped at an edit point where recording of a second video signal is to commence. Then the tape is run reversely while control signals associated with the locations of the tracks are reproduced. These control signals are counted and the tape is stopped when a predetermined number of such signals have been counted. Thereafter the tape is advanced to a noiseless-still-picture position, based on a counted number of oscillations associated with rotation of the tape capstan, at which an acceptably noise-free picture is obtained, notwithstanding that the head scan of the rotary heads does not completely concide with the slant tracks when the tape is stopped. After this, the tape is run at normal speed, and when the tape reaches the edit point, the VTR begins to record the second signal, which is at that time in step with the pre-viously-recorded first video signal.                             -i-

Abstract: ABSTRACT OF THE DISCLOSURE            Method and apparatus for reducing fuel consumption in an internal combustion engine.            An internal combustion engine (M) is fitted with two diffe-rent means for increasing fuel efficiency : a Rankine cycle circuit for recovering heat energy dissipated by the engi-ne ; and a supercharger (S). The recovered heat energy is transformed into mechanical energy by a turbine (T), and may be applied directly to the engine's output shaft (10).          The supercharger (S) is driven mechanically from the engi-ne's output shaft (10). This arrangement enables the effect of the means for increasing fuel efficiency to be substan-tially cumulative by preventing one of said means from redu-cing the potential gain in efficiency available from the other.

Abstract: BASKETBALL SHOE SOLE                     ABSTRACT OF THE DISCLOSURE      An outer sole especially designed for basketball shoes which is lightweight, stable, and provides a greater degree of shock absorption than heretofore possible.  The sole includes a plurality of kinetic levers or tread members which extend down-wardly and outwardly from the peripheral portion of the bottom of the sole and, together with a relatively stiff, centrally formed pedestal on the inside surface of the sole, define a cantilevered construction that dissipates shock by inducing spreading of the levers laterally outwardly upon foot-induced ground impact.  The space between the inner, central pedestal and the side wall of the sole defines a cavity positioned above the respective tread members for facilitating compression and spreading thereof to enhance the shock-dissipating qualities of the sole.  The sole also includes a side wall which, together with the upper walls of the tread members, defines a groove. The groove also facilitates compression and spreading of the tread members.  The wider than normal base provided by the laterally extending tread members enhances stability and reduces the possibility of ankle twists.  The forefoot portion of the bottom of the sole features a transversely extending groove pattern and a pivot stud which together facilitate metatarsal flexure and pivoting which are frequently encountered when playing basketball.

Abstract: Abstract The disclosure relates to a cheek plate unloading slipper vane pump for supplying fluid to a system.  A fluid passage in the cheek plate receives flow from the contracting pockets.  The passage has a portion directing flow from the contracting pumping pockets radially inwardly of the cheek plate.  A tubular member is fixedly attached to the cheek plate coaxially with the axis of relative rotation of the rotor, and the interior of the tubular member communicates with the portion of the fluid pa-sage directing flow radially inwardly.  A housing member that defines a chamber in which the cam ring, rotor and cheek plate are located has a discharge orifice coaxial with the tubular member.  A seal is provided between the tubular member and the housing member enabling the tubular member to move with the cheek plate relative to the housing member while maintaining the seal.  A drop in the output flow rate is achieved by a variable control orifice which is in part defined by a tapered surface on the tubular member.  As the cheek plate and tubular member move away from the cam and rotor, the tapered surface moves to decrease the size of the control orifice to thereby decrease the pressure acting on one end of a servo valve spool that controls pressure in the cheek plate cavity and reduce the output flow of the pump.

Abstract: ABSTRACT OF THE DISCLOSURE         A seat back recliner comprises an infinitely variable mechanism which positions the seat back angularly relative to the seat cushion about a hinge axis in one-to-one correspondence with operation or an operating lever. Once the seat back has been positioned to a desired setting by operation of the lever, the seat back remains in the selected position.  External torques applied to the seat back about the hinge axis tending to displace the seat back from the selected position are resisted by a locking action between wedging members in the infinitely variable mechanism. When it is desired to position the seat back, operation of the lever is effective to rotate the seat back to the desired position while concurrently interacting with the wedging members so as to prevent the wedging members from disallowing the desired rotation.

Abstract: Abstract A torque absorbing coupling for a hydrostatic steering system which a hydrostatic steering controller responds to operation of a steering wheel to direct flow from a source to a steering motor.  The coupling minimizes the possibility of a high reaction torque being felt by the operator who turns the steering wheel more rapidly than the system can deliver flow and pressure to the controller to levels which are sufficient to effect steering as demanded by the operator.  The coupling is provided between the steering wheel and the controller's metering unit, and operates to absorb reaction torques over a time intervals and thereby delays transmission of those reaction torques to the operator over that time interval, to provide the system with an additional time interval to increase flow and pressure to the levels demanded.

Abstract: NOZZLE COOLED BY HEAT PIPE MEANS          ABSTRACT OF THE DISCLOSURE          A tubular member (40, 40') which has heat pipe cooling means (48, 48') cooperatively associated therewith and which is particularly suited for use in the manner of a nozzle for purposes of effecting the introduction of fuel, air, etc. into a substantially closed area 12 in which combustion takes place.  The subject tubular member, i.e., nozzle, (40, 40') is suitably supported relative to the aforesaid combustion area (12) such that one end (30, 30') of the former (40, 40') communicates with the interior of the combustion area (12) and the other end (32, 32') thereof communicates with the exterior of the combustion area (12).  Heat pipe means (48, 48') having an evaporator, i.e., hot, end and a condenser, i.e., cold, end is suitabiy supported in surrounding relation to the tubular member (40, 40') so as to be operative to effect a cooling of the latter (40, 40').  Within the heat pipe means (48, 48'), there is established a flow path along which a continuous flow of fluid occurs.  In accord with this flow path, fluid in the form of a liquid flows through capillary action from the condenser end to the evaporator end of the heat pipe means (48, 48').  At the evaporator end of the heat pipe means (48, 48'), the liquid absorbs sufficient heat from the combustion area (12) that it vaporizes.  As a vapor, the fluid then flows back from the evaporator end to the condenser end of the heat pipe means (48, 48'), where it is cooled and condenses.  Thereafter, as a liquid the fluid once again commences its travel along the flow path provided therefor within the heat pipe means (48, 48').
