Abstract: ABSTRACT A circuit for varying the amplification afforded to a-c signals transmitted through a transmission line in accordance with the a-c losses of that transmission line.  Gain control circuitry is provided which varies the magnitude of amplifying voltages and currents inserted into the  transmission line in accordance with the a-c losses of that transmission line.  The gain control circuitry is comprised of a line resistance sensor which establishes a control signal which is a function of the a-c losses of the transmission line.  The line resistance sensor establishes the control signal by establishing one signal which varies in accordance with the voltage across the trans-mission line and another signal which varies in accordance with the current through the transmission line and then dividing the signals one into the other to thereby establish the control signal.  This control signal is applied to the remainder of the gain control circuitry to vary the magnitude of voltages and currents inserted into the transmission line in accordance with that control signal.  As a result, the gain control circuitry automatically adjusts the gain of a repeater in accordance with each transmission line connected thereto.

Abstract: ENGINE FAN CLUTCH                          ABSTRACT OF THE DISCLOSURE A fan clutch for a vehicle engine connects the engine cooling fan with the engine when the cooling effect of the engine fan is necessary and disconnects the fan when its cooling effect is not necessary.  The clutch includes a driven member and a driving member and a belt carried by the driving member and rotatable therewith which is adapted to engage the driven member when the clutch is to be engaged.  The driven member comprises a pair of rela-tively rotatable, axially extensible portions so that when the below is in driving engagement with the driven member, relative rotation between the portions extends the same so that engagement surfaces on one of the portions and on the driving member are brought into engagement thus connecting the driven and driving members.  A spring, which is responsive to centrifugal forces generated by rotation of the driving member, holds the belt in driving engagement with the driven member when engine speeds are below a predetermined level, but yields to permit the belt to move out of engagement with the driven member when engine speed exceeds the predetermined level.  A temperature responsive capsule in-cludes a lever which holds the spring in a position maintaining engagement of the belt with the driven member when the temperature level exceeds a predetermined level, regardless of engine speed.

Granted: 1980-08-26
Abstract: ABSTRACT            An automatic swimming pool cleaner comprised of a car adapted to travel underwater along a random path on the pool vessel surface for dislodging debris therefrom. The car wheels are driven by a water powered turbine to propel the car in a forward direction, along the vessel surface.  In order to prevent the car from being driven into a position, as for example against a vertical wall, from which it cannot emerge, a wheel geometry is employed which, upon contact, develops a horizontal force component parallel to the vertical wall, to thus enable the car to spin off. Alternatively, or in combination, a water flow produced reaction force can produce a torque to turn the car with respect to the engaged wheel to enable the car to spin off. The car is designed with a low cen-ter of gravity and a relatively buoyant top portion so as to produce a torque which maintains the car correct side up when on the pool bottom. Means are provided on the car for producing a water flow having a force component perpendicular to the vessel surface to provide good traction between the car wheels and the vessel surface. Further, a water flow produced suction is created adjacent to the vessel surface for collecting debris into d basket carried by the car. In addition, one or more hoses is pulled by the car and whipped by water flow to sweep dirt from the vessel surface.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to a combination coal liquefaction-qasification process wherein hydrocarbonaceous mineral reside-containing slurry from the liquefaction zone is recycled to the liquefaction zone and all non-recycled hydrocarbonaceous mineral reside-containing slurry is passed to a gasification zone for conversion to synthesis gas to supply hydrogen for the liquefaction zone.  It has now been discovered that in this process a surprisingly high reaction selectivity in favor of the desired distillate oil product is archived by combining low liquefaction zone residence times and relatively high rates of recycle of mineral reside-con-taining slurry compared to feed coal rate.  Under these conditions the yield of the desired distillate oil product can be increased to an unexpectedly high level while the yields of both higher and lower boiling products are each being decreased and while hydrogen consumption is being reduced.

Abstract: ABSTRACT An environmental control hood assembly includes a headpiece and a noise filter subassembly which is disposed within the headpiece adjacent its top wall. The filter subassembly includes a silencer member with an air-permeable wall portion and is connected to the conduit which in turn is connected to the source of air under pressure. The silencer member in turn is disposed within a foam member which is fabricated of an air-per-meable synthetic resin open cell foam so that air introduced into the silen-cer member must travel a path through the silencer member and through the foam with resultant reduction in the sound level of that air. A barrier may be provided under the silencer to preclude direct flow of air from the silencer downwardly through the foam, and the filter subassembly may in-clude a bottom sheet of an air-pervious material.

Abstract: ABSTRACT           The drive mechanism for a paper tape punch and reader assembly utilizes tape drive assemblies which move the paper tape in response to the application of continuous periodic motion and control signals.  The periodic motion serves to oscillate a rocker plate between first and second limits and the control signals serve to selectively engage and disengage a detent which effects coupling between the drive shaft and the source of periodic motion.  The periodic motion is imparted to the drive assembly by a connecting link which in turn is driven by an adjustable eccentric. The eccentric comprises a pulley plate which is fixed to a shaft.  A circular body is adjustably movable with respect to the pulley plate and is arranged to engage the race of a ball bearing assembly which further comprises balls and a retaining ring.  The connecting link has a circular opening which provides a snug fit to the exterior of the retaining ring.  The pulley plate and the body are held in a fixed physical relation by two locking screws and the relative position of the two is established by an eccentric which is mounted on one of the locking screws.
