Abstract: ABSTRACT             The invention is concerned with a method of controlling a power transmission device between a driving engine and a drive axle comprising a torque converter and an automatic step gearbox, and a control system for con-trolling such a power transmission device.  In the gearbox, an electric control device with a microcomputer permits the operator to select, by means of a direction selector, the desired driving direction of the vehicle even when moving opposite to the desired direction.  When such a directional command signal is sent to the control device, the reversing gear control means reverse the working direction of the gearbox to make it work in the opposite direction to the driving direction.  This signal is also sent to the drive gear control means in the control device, which means during retardation maintain the engaged gear in engagement.  If the highest gear is engaged when the command signal is changed, however, downshifting to the next higher gear immediately takes place, which gear is then maintained during retardation.          The reversing gear control means are prevented from reversing the working direction of the gearbox if the vehicle speed exceeds a predetermined maximum value.  The beginning of the retardation is then carried out with the working direction of the gearbox unchanged until the speed has dropped below the maximum value, and then the working direction is reversed.

Abstract: ABSTRACT OF THE DISCLOSURE      A powered dental scaler (10) is disclosed of a type which drives a vibrating scaling tip (26) in a circular or ellipsoidal pattern of motion.  A scaling tip (26) having working surfaces provided by the edges (104, 106, 108) of an elongated, curved element which has a cross-sectional configuration in the shape of a multi-sided figure, e.g., a triangle or a diamond, is particularly useful with a scaler having this type of vibrational pattern.  Each of the longitudinal edges (104, 106, 108) has a radius of curvature in the range of about 0.001 inch to about 0.005 inch.  The free end (94) of the scaler work tool (26) preferably terminates in rounded or ball-shaped configurations, and the working surfaces can be joined along inactive edges by a convex surface (116) to provide "safe" surfaces.  The absence of sharp edges or points on the scaler tool work surfaces substantially reduces the likelihood of damage to tooth dentin, cementum or gums.

Abstract: A B S T R A C T         A pilot operated pilot valve which is adapted to employ a low-wattage solenoid for operation of the pilot valve which functions as an amplifier to control or drive various types of larger air valves, such as a four-way valve, a three-way valve, a two-way valve and the like. The pilot valve includes a valve body with an inlet port, an exhaust port, and a cylinder port for directing pilot air to a valve to be controlled. A poppet spool valve is mounted in the valve body to control the flow of air between said ports. The poppet spool valve is biased to an inoperative position, by a return spring and by a pilot air assist return action, so as to block flow between the inlet port and the cylinder port but allow flow be-tween the cylinder port and the exhaust port. A low wattage solenoid blocks an exhaust passageway system when it is de-energized to allow the return spring and pilot air to hold the poppet valve in an inoperative position.          When the low wattage solenoid is energized, the last mentioned exhaust passageway system is closed and pilot air is then allowed to flow through an orifice in the top of the poppet spool valve into a chamber above the poppet spool valve and react against the effective top end area thereof, and move the poppet spool valve to an operative position to open a passage-way between the inlet port and the cylinder port and block off any flow to the exhaust port.

Abstract: DUAL SPEED HYDRAULIC PISTON ASSEMBLY                       Abstract of the Disclosure Liquid fluid pressure applied to a piston causes advancement thereof at a rapid rate until an external resisting load applied to the piston rod exceeds a predetermined value producing a corresponding increase in the pressure within the opposing pressure chambers to which the piston is exposed.  Bi-directional flow, conducted between the opposing chambers during rapid piston movement, is automatically blocked by a differential circuit pressure operated piston valve to cause a rapid increase in the differential pressures acting on the piston, and an increase in the value of the external piston rod load with a corresponding decrease in its rate of movement in the same direction.  A modified embodiment permits the piston rod to act under pressure and with a force in both the extending and retracting phases of the stroke with the same rapid extending rate until the external resisting force is encountered.

Abstract: ABSTRACT:         A battery backup circuit for an MOS memory which has a multiplexed pin (WE) that functions to provide backup power to a memory cell array (50) upon loss of primary power Vcc. A voltage comparator (10) detects when the primary power Vcc becomes less than the backup voltage on the WE terminal.  Upon detection of loss of primary power the memory cell array (50) is powered by a connection to the WE terminal.  A primary power status signal (POK) indicates the status of the primary power and is driven to a state indicating insufficient circuit voltage for normal operation when Vcc drops below an acceptable limit or when there is inadequate substrate bias.  The circuit of the present invention further generates an inhibit signal to prevent the operation of peripheral circuits (70) to write data into the memory cell array (50) upon detection of a failure of primary power.  The inhibit signal is generated when primary power is lost or when the substrate bias is inadequate.  A low-power auxiliary pump generator (92) provides a sufficient substrate bias to maintain the data pattern in the memory cell array (50) during the backup mode.

Abstract: ABSTRACT            My invention relates to stereoscopic television using relative camera to scene translating motion and does not require optical aids at observer's eyes, presents a horizontal parallax (Hologram like) 3-D full motion scene to a wide audience, has no dead zones or pseudo 3-D zones over the entire horizontal viewing field and operates on standard broadcast television signals re-quiring no changes to the television studio equipment or the home television antenna.  The only change required at the receiving end is a special television projector. The system is compatible with pre-recorded standard color television signals.  The cathode ray tube is eliminated by substituting an array of solid state charge couple device liquid crystal light valves which have the proper-ty to receive television fields in parallel from memory and which are arrayed in an arc for scanning purposes. The array contains a scrolled sequence of successive television frames which serve as the basis for 3-D hori-zontal viewing parallax.  These light valves reflect polarized light with the degree of polarization made a function of the scene brightness.  The array is optically scanned and the sequence rapidly projected onto a cylin-drical concaved semi-specular screen that returns all of the light to a rapidly translating vertical "aerial" exit slit of light through which the audience views the re-constructed 3-D scene.

A mold is provided which tapers the thickness of the lid top and which includes a single mold part defining the interior surfaces of a circular lid sidewall and a thin internal flange to be formed with the sidewall.          A molten poleolifin is injected into the mold cavity, and cooled for an emperically determined time so that the sidewall and flange of the resultant lid are partially set but still strongly elastically deformable.  Elastic deformation of the two members is relied upon to permit prying of the lid from the from the said mold part without shearing of the internal flange.  The tapering of the lid top eliminates the warpage which otherwise occurs in an ultra-thin lid when stripped prior to substantially complete setting from the mold.
