Abstract: Docket 5989 FILL CONTROL FOR AN AUTOMATIC DISHWASHER                Abstract of the Disclosure The recirculating pump output is monitored as the pump is operated during each fill cycle, and the fill is terminated just when the desired pump output is reached.          The output is less than the pump maximum and results from continuous aspiration of water and air into the pump inlet, thus using only the minimum fluid necessary, and automatically reducing fluid consumption during subsequent fills as the washing operation progresses.  The pump inlet faces down-wardly at the bottom of the dishwasher tank to control surging.

Abstract: ABSTRACT OF THE DISCLOSURE         Carriages are provided for conveying odd-size dental film chips through a basic processor and dryer which have been especially adapted for advancing standard size film chips by their edges along vee-grooved paths extending therethrough.  The carriages comprise frames for holding the odd-size film chips and support members transversely disposed on the ends of the frames.  The support members and in the form of thin plates of a size such that they can be advanced along the vee-grooved paths of the processor and dryer in the same manner as the standard size film chips.   The frames of the carriages are provided with opposing pairs. of vee-grooved which engage the edges of the odd-size film chips when slightly bowed.  To enable the odd-size film chips to be dried by the same dryer used for drying the standard size film chips, the vee-grooves of the frames are shaped to reduce the size of the globules of rinse solution that are retained thereon.

Abstract: Re; Patent application Serial No. 295,33o A B S T R A C T     The switching device of the present inventioncomprises at least one driver member, guide means supporting and adapted to guide the driver member for free travel in a predetermined path, at least one movable slave member provided with pivoting means and having at least one free end, pivot means cooperating with the slave member and adapted to support and guide the slave member for free pivotal movement between a first magnetically locked position and a second actuated position. Magnetic elements having predomi-nant magnetic surfaces are arranged on the driver member and on the slave member, with at least one of the magnetic elements being a permanent magnet. With the driver member and the slave member arranged in combination, the respective magnetic surfaces are arranged in relation to each other so that they face and overlie each other to the extent that a magnetic locking act-ion holds the slave member in a first locked position against the magnetic surface of the driver member. Bearing means on the driver member, arranged to be moved into position to make contact with a cooperating position on the slave member, is provided. The cooperating position being chosen with respect to the pivot of the slave member in such manner as to allow the application of a preselected actuating leverage. With the bearing means on the driver member in contact with a preselected position on the slave mem-ber, an actuating force,applied to the driver member, is transferred,thro-ugh the bearing means, onto the slave member. As the driver member is moved in its predetermined path, the slave member is pivoted away from the first magnetically locked position to a second, actuated position. With the slave member in the second position, the magnetic force of attraction being sufficient to reverse the movement of the slave member and the driver member.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention makes extruded, vulcanized, high voltage cables insulated with thermosetting compounds at much higher rates of production and with superior insulation of reduced thickness and with reduced cavities or voids in the insulation.          As the cable comes from an extruder, it passes into a curing chamber with a heat booster that quickly raises the insulation to a temperature at which it is cured much more quickly than with steam heating of the prior art.  A high temperature liquid in contact with the insulation maintains the high temperature; and because of the greater curing heat, the cable can travel through the curing chamber at a faster rate and into a cooling tube where it contacts with a cooling liquid under high pressure.          The insulation compound is treated to reduce the size of cavities; and the high pressure maintained by the curing and cooling mediums prevent expansion of cavities before the insu-lation is set.

Abstract: Abstract of the Disclosure An improved method and apparatus for aligning the front wheels of a motor vehicle utilizing a beam pro-jector and detector assembly on each wheel and an electronic computing means for determining the toe angles of the wheels in response to measured toe signals gener-ated by the detectors.  The computing means first sub-tracts one of the toe signals from the other, multiplies the difference by a selected correction factor to produce a correction signal, and then adds the correction signal to the larger of the measured toe signals and subtracts the correction signal from the smaller one to provide the true individual toe angles of the wheels.  The signal, derived by the computing means are applied to display devices which read out the correct values of the right and left toe angles.  Although the correction factor is dependent on the dimensions of the frame of the vehicle, the steering suspension, and the mounting of the projector and detector assembly, it has been found that a correction factor of approximately 0.28 is indicated for a great portion of the United States automobile and small truck population, whereby a single alignment system incorporating the improvement herein disclosed may be used to provide accurate front-end alignment with only one adjustment of each wheel.  The improved system is particularly useful when aligning vehicles having gross malalignment.  Also, since the system utilizes no reference to the rear wheels of the vehicle, it provides expeditious alignment of vehicles having rear wheels which are not aligned with the front wheels, e.g., as in the case of a truck tractor or motor home with dual wheels on the rear axle.                             -1a-

Abstract: Abstract of the Disclosure A thyristor switching network is disclosed in which the switching network control provides both crosspoint audit and centralized control capabilities.  The switching network control circuit contains three signal generators each of which generates a particular control signal when enabled.  A distribution circuit is also provided to connect each of the signal generators to a corresponding terminal of a selected thyristor crosspoint element.  In this manner, the signal generators directly control the voltage appearing at any terminal of any crosspoint element and can be used to turn on, turn off, or audit the busy/idle status of any selected thyristor crosspoint element.          Also, the thyristor crosspoints are switched on in the zero voltage mode and the dV/dt across the selected thyristor crosspoint element is controlled by the signal generators to eliminate false firing of the thyristor crosspoints,

Abstract: ABSTRACT OF THE DISCLOSURE         A process for producing .alpha.-type calcium sulfate hemi-hydrate or calcium sulfate anhydrite or calcium sulfate dihydrate by a hydrothermal reaction of a starting material of calcium sul-fate in an aqueous medium.  The calcium sulfate produced is in either fibrous and/or spherical form.  The .alpha.-type calcium sulfate is produced efficiently by adding a powdery inorganic substance to a slurry of the starting material.  The addition of the powdery inorganic substance advantageously eliminates difficulties in-volved in the control of the hydrothermal reaction experienced with conventional processes.  The addition of the powdery inorganic substances also enables production of spherical calcium sulfate under conditions unsuitable therefore under conventional processes.
