Abstract: LOW NOISE READ-TYPE DIODE                         Abstract A Read-type avalanche diode having a low noise measure and capable of attaining output signal powers of one watt or more.  An effective injection current is defined as the con-duction current in the avalanche zone in the absence of avalanche multiplication including therein any tunneling current.  The noise measure of the diode is minimized by in-creasing the defined effective injection current with disclosed techniques.  In one embodiment, the effective injection current is increased by the presence of traps located in the avalanche region.  In another embodiment, a Schottky barrier contact having a low work function is provided.  Surface states of the avalanche region are also varied to produce the desired increase. Increased effective injection current may also be produced in a device with preferred heat flow properties.  The noise perform-ance of both oscillator and amplifier circuits is improved with the invention.

Abstract: ABSTRACT OF THE DISCLOSURE     The primary thrust drive for a punch and die set which presses together two superimposed portions of the band to be locked utilizes the mechanical advantage afforded by a symmetrical angle lever pair.  The arms of the levers are turned about a pair of pinions by a pneumatic piston drive.  At the end of the other arms is a pressure roller which rides on a pressure surface of a pressure plate to convert the rotation movement of the angle levers to an outward linear movement on the pressure plate towards the pinions.  The pressure plate carries the die.  The pressure surface upon which each of the rollers acts is made to have a cylindrical curvature away from the roller.  This has the effect of making more linear the characteristic increase of the mechanical advantage of the toggle arrangement as a function of the outward travel of the pressure plate and thereby making the adjustment of the die travel less critical.

Abstract: ABSTRACT OF THE DISCLOSURE A method is disclosed for controlling a process for the recovery or zinc from zinc sulfate electrowinning solutions containing concentrations of impurities. The disclosed method includes the steps or establishing a test circuit comprising a test cell, a sample or electrowinning solution, a cathode, an anode and a reference electrode immersed in said sample, a vari-able voltage source and measuring means electrically connected to the elec-trodes.  A potential is applied to the electrodes in the test cell to obtain a predetermined potential between the cathode and the reference electrode. The potential is decreased from the predetermined value at substantially zero current, the decreasing potential is measured, and the decreasing of the potential is terminated at a  value corresponding to the point at which zinc starts to deposit on the cathode and the measured electrode current density increases rapidly from a value or substantially zero for further small decreases in potential.  The activation over-potential is determined and is related to the concentration of impurities in the sample, whereupon the process for the recovery of zinc is adjusted to obtain optimum zinc re-covery.

Abstract: ABSTRACT            DEMAND PACER WITH PROGRAMMABLE                   RATE HYSTERESIS            A demand pacer has a local memory element, programmable from a remote source, which detects whether or not the hysteresis rate adjustment is to be employed.  When hysteresis is disabled, the pacer operates in the normal demand mode, at a rate optionally selected by the same memory.  In the hysteresis mode, a flip-flop controls gating means, ultimately operable at conventional or hysteresis rates, ultimately for controlling the output amplifier.  An input amplifier senses natural heart beat signals, and enables a gating means, which has been conditioned for hysteresis mode operation, to reset the flip-flop and in turn the output controlling gates.

Abstract: ABSTRACT      Electrostatic printing and photocopying providing for en-hanced image quality at high speeds.  After separate formation of a latent electrostatic image on a dielectric member both the printing and photocopying apparatus may employ identical toning apparatus.      In the photocopying apparatus an image is optically created on a precharged photoconductor and transferred to the dielectric member.  A semiconductor substrate is preferably in-cluded in the photoconductor member for enhanced image transfer quality.  In the printing apparatus an electrostatic image is formed.  For example, on an imaging roller by an ion generator comprising two electrodes separated by a solid dielectric, with a high frequency alternating potential used to create an air gap breakdown in a region at a function of one of the electrodes and the solid dielectric.  A direct current extraction potential applied to the junction electrode is used to extract ions from the discharge thus created.      The ion generator and extractor may also be used in photo-copier and other applications.  The image bearing dielectric member advantageously consists of impregnated anodized aluminum oxide, with high resistivity, and good hardness and smoothness to ensure essentially total transfer of the toned image to a receptor medium.  This transfer may be effected with simul-taneous image fusing by passing the receptor between the image roller and a backup roller under high pressure.  Provision may be made for removing toner remaining on the two rollers, and to erase any latent electrostatic image on the image roller.

Abstract: IMPROVED EFFICIENCY AIR CYCLE ENVIRONMENTAL CONTROL SYSTEM     ABSTRACT OF THE DISCLOSURE  .   In a compressed air powered refrigeration system for aircraft containing a refrigeration turbine and associated heat exchangers for supplying cool air to the aircraft cabin, air is recirculated from the cabin by a recircula-tion means and combined with the turbine discharge air to simultaneously melt ice present in the turbine discharge and provide cooling to the recirculated air.  The lack of ice in the turbine discharge allows the use of an ice-free regenerative heat exchanger, in heat exchange relation with the mixture of the turbine discharge air and recirculated cabin air, to condense moisture from the air entering the turbine.  The use of heat from the cabin air to mel~ ice coupled with maximum utilization of the recirculation means supplying the recirculating cabin air enables the turbine to provide air at a temperature below freezing and results in improved cycle efficiency as well as maximum possible ventilation rate to the load.

Abstract: FORCE LIMITING DEVICE FOR AN ACTUATOR ROD                 Abstract of the Disclosure A force limiting device for an actuator rod is used on a valve actuator of the type which includes hydraulic fluid being selectively applied to and discharged from a cylinder at a first side of a piston connected to the actuator rod as high pressure gas of an accumulator mounted on the cylinder acts in opposition thereto on a second side of the piston.  The piston includes an interior cylindrical bore narrowing to an opening at the first side thereof which receives the actuator rod slidably therein.   The actuator rod extends from the first side of the piston through a hole in the first end of the cylinder for coupling to a valve stem outwardly of the cylin-der.  An enlarged piston head is secured at a first side there-of to the other end of the rod and disposed within the interior cylindrical bore for sliding, sealed contact with an interior of the bore.  Atmospheric pressure communicates with the bore to act on the second side of the piston head.  The hydraulic fluid produces a pressure on the first side of the piston head which is opposed by atmospheric pressure at the second side to produce a maximum tensile force on the actuator rod when the piston is held against the piston stop at a second end of the cylinder by the hydraulic fluid which produces a force on the piston greater than the maximum tensile force on the actuator rod.
