Abstract: The present invention relates to a sieve electrode for connection to a nerve stump, which is composed of a thin flexible substrate (1) with a plurality of ports (2) for nerve filaments and several electrodes (3) that are disposed on at least some of said ports (2) on said substrate (1) and adapted for being electrically contacted via conductors (5) on said substrate (1), as well as of at least one counter-electrode (4). The substrate (1) presents tabs (6) protruding from the edge for fixing the substrate (1) on a face of the nerve stump, which serve, at the same time, as carrier of the counter electrode (4).

Abstract: A gas-fired infrared radiation emitter with a frame, a screen removably attached to the frame, and a device for locking the screen to the frame. At least three receptacles are connected to each side of the frame, and at least one support is connected to each end of the frame. Three retaining bars extend from one side of the frame to the other and are used to lock secure the screen between such bars and the frame; and a fourth retaining bar extends from one end of the frame to the other and also secures the screen.

Abstract: Disclosed is a device and a process for examining cells using the patch-clamp method. A plane arrangement is used of a first number of micro-cuvettes for receiving cells and a plane arrangement of a second number of micro-pipettes which can be positioned in relation to the plane arrangement of micro-cuvettes in such a manner that a multiplicity of cells located in the micro-curvettes can be examined simultaneously.

Abstract: An apparatus for drying a moving substrate containing a multiplicity of infrared emitters and a detection emitter and a device for supplying a mixture of air and gas to these emitters. The detection emitter contains an emitter body with a diffuser for distributing a fuel-oxygen containing gas mixture, a primary radiator having a combustion surface integrally connected to the emitter body, a first detection electrode, and a second detection electrode; each of these detection electrodes sends a signal to a control means when it senses the presence of flame-induced ionization. If the control means receives a signal from one but not both of these detection electrodes, it will continue supplying the air/gas mixture to the emitters. However, only when the control means ceases receiving a signal from both of the detection electrodes will it ceases allowing the supply of the air/gas mixture to the emitters.

Abstract: A gas fired infrared radiation emitter which contains a back-body provided with a distributor, a primary radiator having a combustion surface, and frame which contains four receptacles, each of which is integrally connected to the frame. A screen is removably attached to the frame receptacles by means of two bars, each of which is disposed within the receptacles and is free to move within the receptacles in either direction for a distance of at least about 0.15 inches. Stop surfaces are provided, however, for limiting the amount of longitudinal movement of the bars within the receptacles. The bars each have a length which does not exceed the length of the frame; and they can readily be removed from the receptacles.

Abstract: A device for lifting the abdominal wall for conducting endoscopic examinans and surgery within the abdominal cavity having a handling section and a spiral shaped section which is provided with at least one pitched winding, where the distal end of the spiral-shaped section is provided with a larger spiral diameter than the proximal side.

Abstract: The invention provides a sensor arrangement for monitoring the concentrat of moisture and gaseous substances in ambient air. A gas sensitive intermediate layer is sandwiched between top and bottom electrodes, each of which comprises first and second interdigitated conductive elements, which are coupled to an opposite polarity voltage. The top and bottom electrodes are super-imposed on opposite sides of the gas-sensitive intermediate layer, with fingers of the top electrode having a voltage polarity which is opposite that of adjacent super-imposed fingers of the bottom electrode.

Abstract: The invention pertains to a solid-state chemical sensor with a substrate support. On one side of the support is mounted a heating element with branch circuit connections. On the other side interdigital electrodes are arranged and thereon a carbon dioxide-sensitive material, which comprises CuO and TiO.sub.3, as well as additional metal oxides, in the form of a thick film of approximately 20-200 .mu.m.

Abstract: The present invention relates to a cuff-electrode that can be placed as an extraneural, sleeve-shaped electrode about a biological tissue, e.g. a nerve.

Abstract: A flexible and non-conductive, artificial, implantable nerve plate has an module of about 3000-1000 N/mm.sup.2 and a thickness of <50 .mu.m for placement and insertion between the fascicles of a nerve bundle. Multiple electrodes are arranged on the two sides of the nerve plate, which is connected via conducting lines inside the nerve plate to a cable integrated with the nerve plate; and the cable is connectable to a control and signal receiver unit.

Abstract: An apparatus for measuring the mechanical properties of biological tissue d the use of the apparatus is provided. The apparatus generates a magnetic field by means of a coil system comprising a permanent magnet as the actuator and a conductive foil as the sensor.

Abstract: Sensor provided with a thin membrane, capable of storing electrical charges, whose surface is in contact with the chemical, biological, and/or other physical parameters to be measured. The membrane is part of an electromechanical resonance circuit, operating with propagating acoustic waves. Provision is made opposite the membrane for converters, equipped with interdigital structures, to act as transmitter and receiver for the propagating acoustic plate waves. Each of the converters is equipped with interdigital structures that act as narrow band, filters. The transmitter converter and the receiver converter is arranged with a distance between them. The signal from the receiver converter is detected capacitively. A suitable electronic control and evaluation circuit or feedback is provided in addition between the output signal of the receiver converter and the transmitter converter.

Abstract: A process for drying a web of material moving at a speed of at least about 150 feet per minute. In the first step of the process, a web of material is contacted with a first mixture of air and flue gas while passing the web under a first air nozzle. Thereafter, a portion of the first air/flue gas mixture is exhausted through a first exhaust nozzle disposed less than 12 inches away from the first air nozzle. Thereafter, the web is passed under a multiplicity of gas fired infrared radiation emitting burners while contacting said moving web with infrared radiation and flue gas and heating said moving web to a temperature of from about 100 to about 280 degrees Fahrenheit. Thereafter, the web is contacted with a second mixture of air and flue gas while passing it under a second air nozzle.
