Abstract: WASHER SYSTEM FOR TRANSPARENT     SURFACES ON A VEHICLE            Abstract of the Disclosure:         A washer system for transparent surfaces such as headlamp lenses and windshields has a liquid delivery chamber of a predetermined volume which is supplied with liquid through a one-way valve from a liquid storage chamber having a larger predetermined volume.  The liquid in the delivery chamber is expelled from the chamber through passages and nozzles by air pressure which is stored at high pressure in an accumulator.  The air in the accumulator is controlled for selective delivery by the operator.  The accumulator is replenished with air automatically by an air compressor.  A pneumatic delivery passage is connected between the top of the liquid delivery chamber and the nozzle passages to assist in exhausting the liquid in the passages through the nozzles and after the liquid is expended to permit air in the chamber to escape during refilling of the chamber with liquid.

Abstract: FEEDER HOUSE FOR A CROP HARVESTER     Abstract of the Disclosure The feeder house of a self-propelled combine harvester carries a front-mounted gatherer which delivers crop material to a forward inlet of the feeder house which is pivotally supported by the combine separator body, and delivers crop material to an inlet of the separator.  A pair of side-by-side, contra-rotating auger conveyors deliver crop material directly to the separator rotor in a relatively concentrated high-speed stream.  Convergence and concentration of the harvested crop material begun by a grain platform auger is continued by a pair of transverse beaters, each including helical conveying elements, arranged in tandem ahead of and partially above the dual auger conveyors.  A forward beater close to the feeder house inlet receives material directly from the platform auger and conveys it rearwardly over a floor somewhat elevated with respect to the auger conveyors and transfers it to a second beater above the forward end of the dual augers which directs it downwards into the auger conveyors.  A hold-down rod, generally parallel to the axis of the conveyor augers, is provided above each auger to assist in controlling the transfer of crop material from the rear beater to the augers.  Portions of the feeder house also playing an important part in the control and conveying of crop material include the floor beneath the first beater, converging ramp-like surfaces in the feeder house side walls downstream of the rear beater, and the particular spacing from the auger conveyors of the feeder housing wall portions surrounding them.

Abstract: CARDIAC PACEMAKER WITH DESTRUCTIBLE MEANS         FOR OUTPUT MODE SELECTION   AND METHOD OF MAKING SAME                   ABSTRACT OF THE DISCLOSURE            A cardiac pacemaker which can be manufactured in a wide variety of models having different output modes.  There is mode selection circuitry, common to a plurality of output modes, and including a destructible means, such as one or more fusible links.  A predetermined link or set of links is fused to select the desired output mode. Selection of an output mode determines a set of output pulse parameters.  A variety of pulse rates, pulse widths, hysteresis and refractory modes may be selected.  The mode selection circuitry is such that reconnection of the circuit across the fusible links (via dendrites, wire bond chaff, solder balls, etc.) causes the pulse width to widen, pulse rate to go to 70 ppm., the hysteresis to be shut off, and the refractory to go to 325 milliseconds. A subcircuit prevents the outputs of the mode selection circuit from floating when the links are fused.

A shutter assembly is positioned between the two openings, and includes a shutter having a forward extension which defines a recess therebeneath.  The shutter is moved forwardly and back-wardly by actuator means from a position wherein both openings are closed, to a position wherein, both openings are open, to a position wherein only the outlet opening is closed.  The pre-compression piston is effective to form accumulated dry ice snow into a charge block, which is then admitted to the press chamber by moving the shutter to its fully open position.  Thereafter, the press piston forms the charge into a block of dry ice.          The shutter is then shifted to the outlet only closed position, and the press piston elevates the block into the recess.  Finally, the shutter is returned to its fully closed position, and at the same time moves the dry ice block away from the apparatus to a transfer means.
