Abstract: SYSTEM FOR AND METHOD OF CONTROLLING THE NERVOUS SYSTEM OF A LIVING ORGANISM            Abstract of the Disclosure A novel method for controlling the nervous system of a living organism for therapeutic and research purposes, among other applications, and an electronic system utilized in, and enabling the practice of the invented method.   Bioelectrical signals generated in specific topological areas of the organism's nervous system, typically areas of the brain, are processed by the invented system so as to produce an output signal which is in some way an analog of selected characteristics detected in the bioelectrical signal.  The output of the system, typically an audio or visual signal, is fed back to the organism as a stimulus.  Responding to the stimulus, the organism can be  trained to control the waveform pattern of the bioelectrical signal generated in its own nervous system.         The invented system comprises means for frequency filtering, rectifying, integrating and amplifying.  In addition, the system includes means for transducing the processed signal and displaying it as an output to the subject.

Title: Method for producing semiconductor matrix of light-emitting elements

IPC: H01L21/324
Filed: 1975-06-05
Granted: 1978-12-05
Abstract: ABSTRACT OF THE DISCLOSURE           Disclosure is made of a method for producing a semicon-ductor array of light-emitting elements, whereby a mask is first applied onto an n-layer of an epitaxial structure consisting of a substrate GaAs of the p+-type of conductivity with layers Ga1-xAlxAs of the p-type and Ga1-yAlyAs of the n-type applied successively onto it, which layers from a light-emitting p-n junction.  The mask is produced by applying a photoresist layer onto the n-layer with subsequent exposure and etching.  This is followed by introducing into the n-type layer, through said mask, an acceptor addition by means of ion implantation.  After this the photoresist layer is removed, and a layer of SiO2 is applied onto the uncovered n-layer.  After this diffusion heat treatment is carried out for a time and at a temperature sufficient to pro-duce in the n-layer regions of the p-type conductivity whose depth is at least equal to the thickness of the n-layer.

Abstract: ABSTRACT OF THE DISCLOSURE         Blends of polyvinyl chloride and modified nitrile rubber are provided which have superior physical properties to similar blends of polyvinyl chloried and normal nitrile rubber. The modified nitrile rubber contain small amounts of tertiary amine groups, which may be incorporated by copolymerizing with the conjugated diolefin and unsaturated nitrile monomer a tertiary amine group containing monomer such as dimethylaminoethyl methacrylate.  The blends can range from rigid or flexible uncured blends, of good impact strength, to rubber compositions of improved green strength, vulcanizable to yield vulcanizates of enhanced physical and abrasion properties.  The rigid blends may be used in containers or pipes and the rubbery blends may be used in wire and cable jackets, hose covers and molded goods.

Abstract: MAKING INSULATED CONDUCTORS Abstract of the Disclosure A conductive element is covered with an insulating material which ix cooled within a predetermined temperature range, and preferably near of at ambient, by moving the conductor first through a cooling trough and then in a plurality of convolutions about spaced grooveless rollers which comprise a capstan. The length of the cooling trough is such that the insulation is not deformed as it engages the capstan and the number of convolutions wrapped about the capstan which is subjected to a cooling medium are determined to insure that the temperature of the conductor exiting from the capstan is at or near ambient. Unlike conventional, grooved capstans, the capability of the grooveless capstan to provide for a variable number of convolutions compensates for temperature differences caused by different conductor designs and/or manufacturing parameters such as line speed and thereby insures that coaxial capacitance measurements taken at the exit end of the capstan are made with the conduc-tor temperature being substantially constant. -i-

Abstract: OIL IMMERSIBLE CURRENT LIMITING FUSE ASSEMBLY                 ABSTRACT OF THE DISCLOSURE      A current limiting fuse especially adapted for in-stallation within the oil tank of a transformer for protecting the latter from the effects of high  magnitude fault currents is provided which is completely fluid-submersible and capable of withstanding severe thermal cycling without damage to the fluid-tight seals thereof.  In addition, the fuses hereof are especially constructed for permitting quick, individual helium testing there-of in order to ensure that the fuse meet required saftey stan-dards.  The main body of the fuse is encapsulated within a fluid-impervious casing of filled epoxy material which is pene-trated by a pair of opposed, end-mounted, electrically conductive terminals each being threadably connected to the body of the fuse and bearing against a respective resilient seal member to form fluid-tight seals between the opposed terminals and the aper-tured ends of the encapsulating casing.  In this manner leakage of oil or other contaminants between the fuse body and encapsulat-ing material is effectively prevented during substantially all conditions encountered in practice.  The seal between the cas-ing and the terminals are preferably supplemented by a rigid, non-porous potting compound emplaced around the terminals over the respective seal areas in order to render the entire fuse assembly essentially tamper-proof.

Abstract: ABSTRACT OF THE DISCLOSURE             The invention relates to a container, for example a tube, intended for substances such as for example fluid or semi-fluid liquids or pastes which can be rather crude.  The container is composed of two more or less dome-shaped parts, the opening-ends of which are joined to each other.  At least one of the dome-shaped parts is made of flexible material, in such a way that this part can be pressed down into the other part having the effect that the container becomes emptied.  In accordance with the invention, the opening-ends of the two dome-shaped parts have arbitrary cross sections, i.e., they can be circular, eggshaped or elliptical, and the size of the container is appropriate for being held between human fingers adjacent to each other.  The container also has organs for resting on the fingers.  In addition, one or both of the dome-shaped parts are specially shaped or coated in order to prevent the fingers from slipping when using the container.  Several containers may form blocks having one or several rows, whereby the containers are joined to each other via the organs used for resting on the fingers.

Abstract: ABSTRACT           This invention relates to data transmission system of the type where a plurality of transmitters are located at a location remote from a receiver and are adapted to transmit information from their location in turn to the receiver.  The transmitters in the case of this invention are each self-powered and have their own trans-mitter timer associated with them.  They are all set to operate from time zero by a master timer and their individual power sources are recharged for the power dissipated in each of their transmissions by a charging pulse that is received over the transmission line. The resetting of the transmitter timers to cause them to transmit in sequence is done during the recharging period which follows the transmissions of the series of transmitters.
