Abstract: ABSTRACT           This invention relates to a portable shelter or tent enclosure having a self supporting frame structure that may be pivotal erected and collapsed for supporting a fabric cover.  The frame comprises at least three substantially U-shaped frame members which are linked at the ends of each of the parallel side arms remote the top of the U at about a common point.  At least two of the three frame members are traceable in an angularly spaced apart position by segments comprising a pair of laterally braced parallelograms pivotal linked to the pairs of side arms.  The frame structure can support a removably securable horizontal frame brace that is easily connected to and removed from the top of the laterally braced parallelogram of the frame and includes arms extending angularly downwardly to the side from the brace to the parallel side arms forming the base of the laterally braced parallelogram thereby providing an effective lateral brace to the frame.

Abstract: ABSTRACT SEMICONDUCTOR STRUCTURE WITH RESISTIVE FIELD SHIELD A segmented semi-insulating polysilicon (SIPOS) layer (26) is used between electrodes (20,22) making contact to the surface of a silicon device in order to shield the surface from the effects of charge on dielectric layers above the surface so as to maintain breakdown voltages.  The segmenting of the SIPOS layer significantly increases the resistance thereof and thereby limits leakage generated by the layer without significantly reducing its shielding capability.

Abstract: ABSTRACT           A power line transient surge suppressor circuit features a nonlinear surge-bypassing network connected to bypass line surges around electrical loads connected to circuit output terminals. A fuse is inserted in series with the network, and blows in the event of short-circuit failure of a regulator device in the network.  A thermal cut-out preferably of the irreversibly actuated type is inserted in series with the suppressor circuit input. A current-limiting heater resistor connected in parallel with the fuse supplies heat to trip the cut-out after the fuse blows, thereby permanently terminating power output to the loads.  A similar suppression network is provided for the earth lead in three-wire systems.

Abstract: VARIABLE SPEED RESISTIVE NETWORK FOR A PNEUMATIC SERVO ASSEMBLY FOR AN ELECTRO PNEUMATIC CONVERTER                ABSTRACT OF THE DISCLOSURE         A resistive network is used for an electro-pneumatic converter so that the speed of the electro-pneumatic converter can be regulated.  The converter includes a reversible DC servo motor having a pair of terminals connected to a pair of lines.  The lines are selectively connectable to a common terminal of a power supply.  The power terminal of the power supply is connected over a variable resistor to a terminal connecting the lines.  Selectively connecting one of the lines to the common terminal causes electrical power to pass through the motor and one for an opposite direction to turn the motor shaft in a selected direction of rotation. The speed of rotation is determined by the position of the variable resistor.  The motor shaft is used in conjunction with a cam that is associated with a nozzle supplied with pressurized gas over a bellows.  The nozzle is moved closer or further away from the cam edge as the bellows expands or contracts.  A line connected upstream of the bellows provides gas at a selected pressure which is proportional to the position of the cam.  The position of the cam is determined by the rotation of the motor shaft.

Abstract: ABSTRACT OF THE DISCLOSURE         In a drill chuck for securing the shank of a tool in a hand-held device, clamping jaws are mounted in a chuck member and bear radially outwardly against the conically shaped surface in a first sleeve into which the tool shank is inserted.  A second sleeve is connected to the first sleeve and is in threaded engagement with the chuck member. A locking or third sleeve is located about the first and second sleeves.  The third sleeve is axially displaceable between a first position and a second position.  In the first position the third sleeve engages the first and second sleeves so that the second sleeve cannot be rotated relative to the first sleeve or the chuck member and the tool shank can be locked by the clamping jaws.  When the third sleeve is displaced into the second position the second sleeve is released and can be rotated relative to the chuck member for axially displacing the first sleeve relative to the chuck member and adjusting the radial position of the clamping jaws.

Abstract: Abstract of the Disclosure A control system for a motor driven wiper on a vehicle window comprises a voltage generator effective to generate a first rectangular voltage wave having a substantially constant frequency and duty cycle and apparatus effective to derive two additional rectangular voltage waves from the first: a second delayed from the first by a first delay and a third delayed from the first by a second delay dependent upon the capacitance of a capacitor affected by moisture on the vehicle window.  One of the second and third rectangular voltage waves may also be inverted.  The three rectangular voltage waves are provided to the inputs of an AND gate having an output effective to trigger a retriggerable monostable multivibrator having an energized output period longer in duration than a cycle of the rectangular voltage wave to drive the wiper motor when the level of moisture on the window in the vicinity of the capacitor is sufficiently high. The first delay may be adjustable by the vehicle operator to vary the moisture sensitivity of the system.  If the capacitor is placed within the wipe pattern just above the inner wipe postion, a fully automatic control may be provided.

Abstract: "IMPROVEMENTS IN PITOT TUBE TYPE FLOW MEASURING DEVICES AND METHODS OF MOUNTING SAME IN LIQUID-GAS TWO-PHASE SYSTEMS" This invention relates to an improved pitot tube type flow measuring instrument for use in pipes and other conduits characterized by a generally diamond-shaped sensor portion constituting a bluff body for splitting the flow that includes at least a large-radiused leading edge in which three or more impact ports are located, a pair of planar portions diverging rearwardly from the leading edge to a transversely-spaced pair of much shorter-radiused side edges that cooperate therewith and the downstream-facing portion of the bluff body to define flow separation zones capable of stabilizing the flow coefficient over a broad range of flow conditions provided that the distance separating them is at least five times either of their radii. The invention further includes the unique method of mounting the probe in two-phase or multi-phase flowing systems where one of the fluids is a liquid and another a gas that calls for tilting the axis of the sensing portion thereof at an angle to the horizontal such that pools of the liquid are trapped in one end or the other depending upon whether the gaseous constituent is hot or cold.

Abstract: ABSTRACT:          Amplifier arrangement.          A high-efficiency amplifier of the class-G type comprises a first transistor (T1), whose collector is connected to a first supply voltage (V1) via a first diode (D1), and a second transistor (T2), which is connected in series with said first transistor and which has its collector connected to a second supply voltage (V2).         The first transistor (T1) is driven via a third transistor (T3), which is arranged as an emitter follower by means of a first current source (5), the input voltage (Vi) being applied to this third transistor. For a low input voltage (Vi) the second transistor (T2) is cut off and the first transistor (T1) is connected to the first supply voltage (V1) via the first diode (D1). Above a specific inputvoltage (Vi) the second transistor (T2) is driven into conduction by means of a driver circuit, so that the first transistor (T1) is connected to the second supply voltage (V2). This driver circuit comprises a first current path which is arranged between the second supply voltage (V2) and the emitter of the third transistor  (T3) and which comprises the series arrangement of a second current source (7), the emitter-collector path of a fourth transistor (T5) and a second diode (D4), and a second current path which is arranged between the junction point (3) between the first transistor and the second transistor (T1, T2) and the common point (11) and which comprises the series arrangement of a third diode (D3), a fourth diode (D4) and a third current source (8).
