Title: Road carpeting machine
IPC: E01C19/48
Filed: 1968-03-29
Abstract: In a road-paving machine material (asphalt, concrete, &c) from a front hopper 4 on a wheeled chassis 31 is fed rearwardly by two parallel scraper conveyers 17, 18 and deposited on the ground in front of a trailing screed and spreader plate assembly 7 carried by a sulb-chassis 6 extending rearwardly from a horizontal pivot 5. The two conveyers are independently driven through infinitely variable speed drives controlled from an operators station 32. The assembly 7 rests on the deposited material and is suspended by adjustable hangers 46 and rods 47 from the subchassis 6. When not in use, the sub-chassis 6 may be raised by a ram and lost motion link (not shown). The machine also includes independent variable-speed hydraulic drives for two reversible distributing augers 35, 36 and for a tamper plate 52. The screed plate 51 and spreader plate 51 a form part of a centrally-split box 45 provided with chain-coupled adjusting screws 67 whereby the plate 51 may be shaped to form a central crown. Lateral extension boxes 60 may be swung into line with the box 45, and extension augers may be coupled to the hollow shafts of augers 35, 36-Fig. 6 (not shown). In the inoperative position shown the boxes 60 may be held raised by cam tracks 62 or by jack bolts. The screed heater 59 may be provided. The front wheels 2 are steerable. The wheels 3 are chain driven from half shafts connected through a lockable differential gear and hydrostatic transmission 10 to an engine 8. Each conveyer, Fig. 4 (not shown), comprises a fixed horizontal plate (19) over which material is swept by transverse slats (26) carried by underlying endless chains (21). Rollers 85 adjacent the front hopper 4 can bear against the wheels of a loading truck to allow loading during advance. In a modified machine, for confined conditions, the hopper 4 is replaced by a long narrow hopper which can be swung about a vertical axis for side loading.

Title: Circuit for photometers and the like having sensing and compensating diodes and utilizing potentiometer for setting the constant of proportionality between the light intensity and the output current
IPC: H03F3/45
Filed: 1968-06-19
Abstract: The intensity of light is measured by a photosensitive circuit comprising a differential amplifier, the input circuits to which include on the one side a photo-diode 1 in association with a linear potentiometer 7, and on the other side a voltage reference diode 2. When operating as an exposure meter, the voltage provided by the potentiometer 7 is adjusted by movement of its slider so as to balance the differential amplifier, or at least attain a predetermined indication on meter 12. The setting of the potentiometer is then a measure of the logarithm of the light intensity (since the photo-diode 1 and reference diode 2 voltages vary logarithmically with current). The potentiometer can thus be calibrated in light values. Features of the circuitry include the emitter follower coupling of the transistors of the amplifier a transistor 6 acting as a high differential or alternating current resistance to provide a low direct voltage drop in the common emitter circuit of the amplifier transistors: temperature compensation in the output of the amplifier by resistor 10 and transistor 11 stabilization of the current through potentiometer 7, provided by transistor circuitry 13-20, including control and temperature compensating transistors 17-20 strapped as diodes. This latter circuitry is thereby designed to compensate for the temperature variations of reference diode 2. In the event of over-exposure, a high voltage occurs across diode 2 and indicator 12 and a trigger circuit comprising transistors 21, 22 is actuated to energize an alarm lamp or a relay (to prevent shutter actuation) connected at terminal 29. Similarly, under-exposure control can be provided by suitable adaptation of the circuit. By replacing meter 12 with a capacitor, provision for delayed shutter actuation, the delay being adjusted by the setting of a variable resistor 24, is possible. The circuit may be wholly or partially formed as an integrated semi-conductor circuit.

Title: Gain control arrangement useful in a television signal processing system
IPC: H04N5/58
Filed: 1976-05-21
Abstract: In a color television receiver, first and second amplifiers are respectively included in the luminance and chrominance channels to permit control of contrast and saturation. The amplifiers have gain versus control voltage characteristics including linear portions extrapolated to cut off at predetermined voltages which may or may not be the same. A first potentiometer is coupled between a source of fixed voltage equal to the extrapolated cut off voltage of the first amplifier and a gain controlling voltage source. The gain controlling voltage may be produced by a circuit including an element responsive to ambient light. The wiper of the first potentiometer is coupled to the first amplifier to couple a voltage developed at a predetermined point of the first potentiometer to the first amplifier to control its gain. A second potentiometer is coupled between a source of voltage equal to the extrapolated cut off voltage of the second amplifier and the gain controlling voltage source to receive a portion of the gain controlling voltage in accordance with the ratio of the extrapolated cut off voltages of the first and second amplifiers. The wiper of the second potentiometer is coupled to the second amplifier to couple a voltage developed at a predetermined point of the second potentiometer to the second amplifier to control its gain. In this manner, the contrast of the receiver may be varied over a relatively wide range while saturation is maintained substantially constant.

Title: Hysteresis compensated reed switch assembly for a position indicating system
IPC: G01D5/251
Filed: 1977-04-30
Abstract: The position of a control rod located within a nuclear reactor is sensed by a position indicating system utilizing low hysteresis reed switch assemblies. Each reed switch assembly includes a reed switch having an alternating magnetic flux field applied thereto through a coil surrounding the reed switch and energized by an alternating current power source. The amplitude of the alternating magnetic flux field is adjusted to be between a first flux level required to close the reed switch and a second flux level required to open the reed switch. The level of the alternating magnetic flux field is preset to be below the second flux level to maintain the switch in the open position until an external flux field is introduced to raise the total flux level above the first flux level to actuate the reed switch to close. The interaction of the alternating and external flux fields negates the hysteresis band of ordinary reed switches and provides a more sensitive and accurate position indicating circuit.
