Abstract: Normaal nerve function is restored across severed ends of a nerve fascicle by inserting between the severed ends a laminated chip perforated with an array of holes each sized to accommodate approximately one axon and each containing at least two electrically conductive regions in ohmic contact with the inner surface of the hole at discrete locations along the axial direction of the hole. Proximal axon segments are permitted to propagate through the holes to join distal segments in random fashion and to be in contact with each of the two electrical contacts. Each contact is part of a circuit pattern capable of monitoring impulses, applying blocking potentials and placing selected pairs of proximal and distal axon segments in electrical contact such that nerve impulses can be routed as desired to restore normal nerve impulse communication and hence nerve function.

Abstract: A control system for a tray type refrigerator ice maker having a motor driven programmer (16) for controlling ice harvest by means of tray rotation and twist for ejecting cubes to a collector bin (24). The progammer also drives an arm (26) for bin level sweep, which, if interrupted by the presence of accumulated bin ice, opens a cutout switch (44) in series with the motor (54). A temperature sensing curie effect magnetic switch (36) is series connected with the bin switch and motor for delaying harvest cycle motor drive until the surrounding tray temperature is sufficiently below freezing to indicate ice presence in the tray. A heater (38) is series connected with the motor and disposed to cause opening of the temperature sensing switch shortly after motor start. A programmer actuated by-pass switch (60) in parallel with the temperature sensing switch is held close to continue motor drive through the remainder of the harvest cycle.

Abstract: An optical filter for use in a solid state color camera containing a plurality of solid state image sensing devices, the filter including a first crystal plate for separating an incident ray into an ordinary ray and extraordinary rays in a direction of 45° with respect to the horizontal scanning direction of said solid state image sensing devices, a second crystal plate for separating the incident ray thereof into an ordinary ray and extraordinary rays in a direction which coincides with the horizontal scanning direction, and a third crystal plate for separating the incident ray into an ordinary ray and extraordinary ray in a direction of -45° with respect to the horizontal scanning direction. The second crystal plate is located between the first and third crystal plates, and the three plates are bonded together in the form of a laminate. The optical filter thus produced provides a point diffusion for an incident ray to direct the diffused rays on the solid state image sensing devices. The optical filter then forms first and second trap straight lines and a third trap straight line extending along the vertical scanning direction of the solid state image sensing devices for distributing a spatial frequency spectrum of a sampled output from the solid state image sensing device.

Abstract: A tension actuated fuel (e.g. gasoline) delivery hose uncoupler is disclosed in which, upon a predetermined tension load being applied to the delivery pump hose, the coupling will automatically uncouple thus releasing one end of the hose which, for example, may remain inserted in the fuel tank of a vehicle driving away from the fuel dispensing pump, and the other portion of the hose which is permanently affixed to the pump. The coupler includes normally closed check valves which, upon uncoupling of the coupler, close thereby preventing spillage of fuel. Further, the coupler is adjustable so that it may be calibrated to uncouple at predetermined tension loads. The uncoupler is structured so as to substantially eliminate the effects of fluid (e.g., gasoline) delivery pressure on the tension load required for uncoupling.

IPC: H03G7/00

Abstract: The drain-source conductance of a wide variety of FETs can be made to conform to a predetermined function of a control signal. An offset (V,) is subtracted from the control signal (V e ). The control signal is then multiplied by a factor c/a and an offset (Vp) is added or subtracted therefrom to derive a modified control signal. The modified control signal is then applied to the gate of a FET 12. The factor and the offset are such that the drain-source conductance of the transistor is substantially the predetermined function of the control signal. When a desired attenuator characteristic defined with respect to a FET is to be provided using a FET having characteristics different from those of the reference FET, the control signal to the FET used can be similarly modified so that the desired attenuator characteristics are obtained. A dual path compressor or expander employing an attenuator (which includes a FET) in its further path can be made to conform to a desired compression or expansion characteristic defined with respect to a similar arrangement and with respect to a reference FET conductance control characteristic. This can be accomplished by making the conductance control characteristics of the FET to be used to conform to the desired conductance control characteristic.

IPC: B21D3/05
Filed: 1987-01-10
Abstract: In this method, the rail, during its passage through the top and bottom rollers arranged offset relative to one another, is repeatedly subjected to opposed bending deformations (maxima, minima) by alternate individual bending via head and foot. According to the invention, the rail is bent in such a way via the rail head during the passage and the maxima and minima are matched to one another in such a way that the rail runs with a constant end curvature having a radius of 15 to 60 m into the last straightening triangle in which this curvature is bent again into a straight line. This straightening method ensures that the rail is virtually free of longitudinal internal tensile stresses on the rail-foot side. The rail is thereby given better fracture resistance and fatigue strength. <IMAGE>
