Abstract: AN OPEN COLLECTOR BIT DRIVER/SENSE AMPLIFIER    Abstract Disclosed is an improved sense amplifier/bit driver circuit including first and second transistors con-nected in a current mirror configuration.  A bit line connected to a plurality of memory cells is connected to the collector of the first of the two transistors while the second of the transistors provides an output at its collector.  A current source is con-nected to the base regions of both the first and second transistors for supplying current when a bit line is to be selected.  Current flow through the second transistor is supplied to additional circuitry including a driver circuit, a clamping circuit and a zero filter circuit.  Also disclosed is a reference voltage generator which accurately tracks the sense amplifier circuit and provides a reference voltage at or near the midpoint between a binary 1 and binay 0 level.  The sense amplifier sustantially senses current rather than voltage and also acts as a high power over driven bit driver.

Abstract: Abstract of the Disclosure My invention comprises a novel method of increasing the effective sensitivity of photoconductors to discharge by ionizing radiations by masking a latent electrostatic image formed by exposure of a subject to ionizing radiations, masking the latent electrostatic image, and then subjecting the masked electrostatic image to light exposure to increase the contrast of the latent electrostatic image.  The thus enhanced latent electro-static image is then developed by either positive or negative development, and the developed image may, if desired, be transferred to a carrier sheet.  The invention reduces the Roentgen level to which a patient is exposed.        One form of apparatus for carrying out this method is shown, comprising a first toning means for masking the latent electrostatic image and means for subjecting the masked electrostatic image to enhancement by flooding the same with light exposure.  A second toning means for developing the enhanced electrostatic image is provided.

Abstract: BF&N 6648 JET DROP PRINTER              ABSTRACT OF THE DISCLOSURE           A jet drop printer includes a reservoir means defining an ink receiving manifold and an orifice means defining a plurality of orifices communicating with the manifold,  A plurality of continuously flowing ink streams emerge from the orifices as ink is applied to the manifold under pressure.  A drop control means control the trajectories of drops which break off from the streams such that drops are selectively deposited upon a print medium. A support plate supports the reservoir means and the orifice means and is held by a support structure.  Piezo-electric transducers are also supported by the support plate and vibrate at a frequency near the natural frequency of the streams, thus causing drops of uniform size and spacing to break off from the streams.  A reaction mass is supported by the support plate and is positioned relative to the transducers, the reservoir means and the orifice means such that a vibrational nodal plane passes through the support plate.  The support structure is thereby mechanically decoupled from vibrations impressed upon the other elements of the printer.

The set consist of (n) groups of tracks, each group having (Sg) tracks.      The record carrier is divided into alternate sectors of data tracks and sectors of servo tracks, each track within a servo sector comprising its own track number within its on a positioning member.  The device comprises a first means for forming a complete track number, composed of firstly the track number read in a group and secondly a trial group number which is formed in a second means and which is variable in an increasing or decreasing sense.      Third means are present for determining the difference be-tween a complete track number formed in the  first means and a complete track number estimated in a fourth means on the basic of the displacement speed of the positioning mem-ber body.  A fifth means is used to compare the magnitude determined by half (Sg) and a signal is produced if this magnitude is smaller than half (Sg), this signal validating the complete track number present in the first means at the relevant instant.

Abstract: SWEEPING AIR STREAM APPARATUS AND METHOD     ABSTRACT    In an automobile air flow system, air is forced through an air outlet element or nozzle (13, 21, 24) in a sweeping air stream pattern by an oscillating reed or vane member (42) supported solely at the downstream end (43) for air initiated oscillatory movement in the flow path of the air from the source; a weight (41) is on the free, upstream end of the vane and is of a size such that the rate of oscillation is determined by the spring constant of a spring in the vane member and the weight. The oscillating vane (42) is proportioned with respect to the cross sectional size of the outlet such that at any extreme of its oscillatory movement is does not physically contact any other structural member.  In one embodiment the oscillating reed is a flat spring which is rendered clickless or silent by limiting directions or bending of the reed element to an axis transverse to the direction of air flow preferably by a bend (78) in the body of the element.     The oscillatory member includes an weight or impinge-ment element secured to the upstream end of the flat spring, the rate of oscillation of the impingement mem-ber being directly related to and substantially deter-mined by the spring constant and the weight of the weight or air impingement element.  In a further emboidment of the vane, a pair of spaced apart, elongated coil springs (91, 92) carry a flexible sheet (95:) therebetween and a weight (98A and 98B) on the upstream end.     The sweep frequency in a defrost system for a wind-shield is low enough compared to the velocity of the jet so that the wavelength is long compared to the nozzle to windshield distance,  This will assure minimal mixing of defrost air with ambient and this maximize the inten-sity of heated air on the windshield.

Abstract: ABSTRACT OF THE DISCLOSURE         A control circuit for controlling the hydraulic suspension system of an articulated vehicle having a first pair of hydraulic cylinders operatively connected between a drive axle and a tractor frame to control vertical bounce movement of the axle, and a second pair of hydraulic cylinders operatively connected between a tractor and a trailer portion of the articulated vehicle for controlling relative roll movement therebetween.  A first valve system directs hydraulic fluid under a first pressure to the head ends of the hydraulic cylinders for supporting the weight of the vehicle and load, and to dampen the bounce motion of the drive wheels and the relative roll motion between the tractor and trailer portions of the articulated vehicle. A gas precharged accumulator and a plurality of flow restrictors disposed in this portion of the circuit, control the spring and viscous damping rates of the cylinders.  A pressure reducer communicates hydraulic fluid under n second pressure, lower than the first pressure, to the rod ends of the hydraulic cylinders and to a second gas precharged accumulator.  The second gas precharged accumulator functions to insure that the rod ends of the hydraulic cylinders remain oil filled, which allows double action of the cylinders and provides cushioning for the rebound portion of the system.

Abstract: ENERGY ECONOMIZER FOR POLYPHASE INDUCTION MOTORS     Abstract of the Disclosure A standard three phase induction motor starts with all three of its input connections connected to the three phase power line. Two of these connections are through triacs which remain continously conducting below said motor's particular most energy-efficient speed, which is above about 95% of syn-chronous speed. This assures full starting torque and un-diminished overload handling capability. The triacs, in re-sponse to a control signal, may open the circuits over a sufficiently wide portion of the sine wave input voltage to substantially maintain said particular efficient speed un-der all rated load conditions. To assure smooth operation and maximum energy savings, the two triacs conduct differently at very light motor loads. The DC control voltage which de-termines the operation of the triacs is generated by a frequency discriminator circuit which receives its information from a load detecting device that is frequency modulated by load/speed related properties inherent to induction motors.
