Abstract: HIGH VOLTAGE GROUNDING SWITCH REQUIRING LOW OPERATING EFFORT            ABSTRACT OF THE DISCLOSURE         A high voltage grounding switch adapted to ground high voltage power lines or other electrical equipment is provided with a two-part blade having toggle type action, with the toggle joint placed near the hinge pivot.  The blade is then rotated from a fully opened position toward a closed position in which the blade end engages an over-head jaw type contact.  The engagement of the blade end with a stop which is adjacent the jaw contact straightens the toggle and forces sliding engagement between the blade end and the jaw contact in an axial direction relative to the blade axis.  A counterbalancing spring is connected from the switch support to the blade in order to at least partly balance the blade mass and to maintain the blade in a toggle-collapsed condition.  The telescoping action of the blade in its stationary jaw contact provides a mechani-cal stop against blowout forces produced by fault currents.

Abstract: ABSTRACT OF THE DISCLOSURE          A circuit breaker has a bistable snap-acting mechanism including a bimetallic arm which renders the circuit breaker capable of actuation by either ambient temperature changes or temperature changes generated internally, as by an excessive electric current,  An electromagnetic arrangement enables essentially instantaneous actuation in response to an electric current of predetermined amplitude greater than the excessive current which otherwise might actuate the circuit breaker thermally.  An actuating lever assembly includes an actuating lever coupled to a link which is normally latched and is un-latched in response to movement of the bimetallic arm, and enables manual actuation, as well as manual reset of the circuit breaker.

Abstract: CIRCUITRY AND SYSTEM  FOR CONTROLLING MULT-USE           ARTICLE DISPENSING CELLS                 ABSTRACT OF THE DISCLOSURE         A circuit and system is presented for controlling operation of a cell or hopper for dispensing, during rotation, controlled quantities of similarly shaped but different small articles, such as drug tablets or capsules of which the number to be dispensed is freely selectable.  In the present invention, a single cell may dispense several different items without fear of intermixing items.   Pursuant thereto, a cell is filled with more articles than required and the system put into operation.  The circuitry for each cell terminates dispensing of an article when the selected number of articles have been delivered to a dispensing chute.  Upon removal of the counted articles from the chute, the cell is again rotated until it is sensed that all articles are dispensed.          The cell is then rendered inoperative.  Upon removal of the excess articles from the chute, the cell is put in a standby position for further operation as desired.

Abstract: Abstract of the Disclosure An air-permeable reactor medium of large surface area and high thermal capacity, coated with a catalyst, is cycled along a closed path across a first duct carrying an air stream laden with oxidizable contaminants and a second duct carrying a stream of fresh air, enabling contaminants in the first air stream to be oxidized to innoucuous byproducts, releasing heat which is transferred to the fresh air in the second duct, the reaction medium moving at a variable speed which is a function of the temperature of one of the air streams; considerable improvement in the efficiency of an industrial oven may therefore be achieved by positioning the reactor medium to exchange heat between an incoming stream of fresh air and a stream of hotter exhaust gas so that the temperature of fresh air delivered elsewhere to the oven may be controlled without having to rely on dampers and mixtures of air volumes with inherent damper malfunctions or mis-metering; also a second burner may be eliminated because of the manner in which the reactor medium is utilized to exchange heat.

Abstract: ABSTRACT         A new and useful improvement in the method for preparing synthetic crystalline aluminosilicate zeolite ZSM-35 is provided.   The improved method comprises synthesizing zeolite ZSM-35 in the presence of butanediamine as template rather than the conventional template of ethylenediamine or pyrrolidine.  Not only is synthesis of zeolite ZSM-35 facilitated by the present improved method, but the zeolite product is substantially more pure than that obtained by the conventional method of synthesis.   Further,  catalysts made with the zeolite ZSM-35 synthesized in accordance hereto are much more catalytically active than those obtained by the conventional synthesis method.

Abstract: ABSTRACT OF THE DISCLOSURE          A source of power rotates a drive shaft upon which a pair of rollers are mounted.  The rollers rotate in a recess and collapse an undialysed blood carrying tube against a wall thus causing a pumping action.  When used with a single needle dialysis system, an occluding pin assembly in-termittently clamps off the dialysed blood carrying tube as said source of power is interrupted in rotation thus permit-ting the device to be used with a conventional single needle assembly.  By rotating a cylindrical member upon the upper end of the drive shaft, the rollers can be retracted from ad-jacent the wall against which the undialysed blood carrying tube rests thus facilitating the engagement and disengagement of the undialysed blood carrying tube with the device.  Inas-much as the wall thickness of such tubes often varies, bet-ween tubing produced by different manufacturers, means are provided to adjust the spatial relationship of the pump rol-lers with the wall against which the tube is pressed during the pumping action.  A hinged lid is provided which, when closed, enables power to flow to the motor.  This lid also includes means to retain the tubes in position during the operation of the device.  The speed of the pump can be varied within limits and the timing sequence of the pump can also be varied within limits.  Means are provided to disable the occluding pin assembly when the device is used with a double needle dialysis system.
