Abstract: Abstract of the Disclosure The invention involves a cell which may be used for producing molten aluminum by electrolysis of aluminum oxide in a molten bath.  The cell includes a cathode and an anode, a bar and a hanger. The bar is connected at an upper end to the hanger and at a lower end to the anode.  Flexible means is provided for supplying electrical current through the bar to the anode. A jack means raises and lowers the hangar and thus the anode.  Included in the invention, the hanger is mounted at at least two separated points, one higher than the other in encompassing, sliding relationship, on a single, upright, circular cross-sectioned post passing through the hanger.  By this technique, the hanger is constrained to move up and down, without rotation about horizontal axes.           The invention additionally involves a clamp including means for providing a backing against which articles to be clamped can be placed, gate means mounted for pivoting about an axle into and out of confrontation with the backing means, the pivot axis passing through the gate means, and means for forcing the gate means toward the backing means at least when the gate means is in confrontation with the backing means. Included in the invention, at least the portion of the gate means at said axis moves toward the backing means during operation of the forcing means in forcing the gate means toward the backing means.           Also provided is a tool capable of operating such a clamp. The tool includes a means for operting the forcing means and a means for pivoting the gate means.

Abstract: ABSTRACT OF THE DISCLOSURE          An electronic control system to regulate heat ing and cooling cycle temperatures in a clothes dryer drying program.  Operation is controlled according to a preselected combination of a heating schedule and a cooling schedule.  Provision is made to sense and control according to the temperature of the air used to dry articles such as clothes in the clothes dryer.  Provision is further made to give a visual indication of the drying program selected and to cancel the program selected and indication thereof upon completion of the drying program or selection of an alternative program.  The final state of the articles being dried is determined by tumbling the articles in the presence of heated force-convected air until the desired state of dryness is obtained and terminating the application of heat and continuing tumbling and forced-convection until the articles are cooled to a desired temperature whereupon said tumbling is terminated.

Abstract: STABILING CIRCUIT FOR CONTROLLED INVERTER-MOTOR SYSTEM            Abstract:       Stabilized operation of an inverter (25) and an a-c motor (412, driven by the inverter, is obtained in the presence of sudden undesired load changes by controlling the inverter so that both the amplitude and frequency of the inverter output a-c voltage will be functions of, and will vary directly with, the d-c bus voltage, with the result that anytime an abrupt abnormal load change causes the d-c bus voltage to vary, a frequency change occurs to compensate for the load change and to stabilize the bus voltage.  By employing the d-c bus voltage to regulate the inverter frequency, if there is a sudden decrease, for example, in the mechanical load (43) on the motor, the d-c bus voltage, which will tend to increase, causes the frequency of the inverter output voltage to increase, thereby increasing the motor speed so that the electrical load change across the d-c bus (26,27) is reduced.  As a result, the d-c bus voltage tends to remain relatively constant in spite of the abrupt mechanical load change.  When there is a normal variation in load demand, necessitating a different steady state motor speed, a set point or reference voltage may be adjusted to change the amplitude and frequency of the inverter output voltage to the levels needed to drive the motor at the new required speed.

Abstract: PHOTOGRAPHIC CAMERA                         ABSTRACT           In a still camera of the 110-format cassette type, an electric motor is provided for winding on the film and thereby priming the shutter by means of a mechanism which engages a perforation in the film as it passes and moves a shutter priming member.  A switch then disconnects power to the electric motor and the camera is ready to expose the next frame of film.  In the event that the camera is operated without a film cassette inserted, a trigger mechanism is provided which directly primes the shutter via a gearing mechanism from the motor.  When a film cassette is inserted in the camera, the trigger mechanism is inhibited and the shutter is primed only by the passing of a film perforation.  Such an arrangement provides a very compact camera and allows the inclusion of an electronic flash unit, if desired.
