Title: Digital setup apparatus for radiation gauging and controlling systems
Inventor: SHOEMAKER DAVID J
IPC: G01N23/16
Filed: 1968-03-29
Abstract: 1,219,001. Radiation gauges; Indicating and recording apparatus. INDUSTRIAL NUCLEONICS CORP. March 29, 1968 [April 28, 1967], No.15314/68. Headings G1A and G1J. A radiation gauge for measuring a property of travelling material comprises means for receiving digital signals indicative of the desired value of said property, logic circuits responsive to the digital signals and selecting the proper one from a plurality of available scales and means responsive to the logic circuits to set calibration circuits of the gauge and indicate the desired value on the gauge recorder. The invention is described applied to a mucleonic thickness gauge for a rolling mill. An operator (using thumb wheel switches) or an automatic controller selects a desired thickness which is stored in a digital memory together with a code indicating the type of alloy being rolled. Logic circuits read the stored desired thickness and produce a signal indicative of the appropriate scale. This scale signal causes illumination of the numerals on the corresponding scale of the instrument indicator/recorder and is used in a logic circuit together with the alloy type code to determine the centre point and span adjustments for the instrument calibration circuits. When the gauge is of the type having a feedback circuit to oppose the output of the radiation detector the adjustments will be made to the gain and off-set voltage of the feedback loop, by changing the settings of digital potentiometers. Scale, composition and target marking A sequencer is provided for sequentially sampling the scale signal, composition signal and target or desired value signal and deflecting a marker pen on the recorder first to a position representing the scale, then to a position representing composition and finally to a position representing the desired value where it stays. The sequencer operates whenever the apparatus starts working, or the composition or desired value is changed or when manually initiated. The marking sequence may be stopped at any point for test purposes. The invention may also be applied to a plastics or rubber calender, a paper making machine, a plastics or metal extruding machine, textile drafting apparatus or a cigarette making machine. It may also be used to monitor a fluid from a chemical or mixing process. The logic circuits, which mainly use resistor and diode matrices, are described in detail.

Abstract: 1,029,685. Fluid-pressure brakes. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. April 9, 1965 [April 17, 1964], No. 15945/64. Heading F2F. [Also in Division B7] Brake means arranged to brake relative angular displacement between tractor and trailer portions of an articulated vehicle is controlled in accordance with the operation of the tractor brakes, means being provided whereby on application of the tractor brakes to an extent less than a predetermined value the brake means is operated to a fixed degree, while operation of the tractor brakes to a greater extent than the predetermined value causes the brake means to be operated to a degree corresponding to the extent to which the tractor brakes are operated. As shown, a compressed air system comprises a service line 6 and an emergency line 7 each associated conventionally with a relay valve 4 controlling the supply of air from a reservoir 5 to trailer brake actuators 1. The service line is also associated directly with the tractor brakes (not shown) and by way of a double-check valve 16 with an actuator 10 of brake means which consists of a disc brake (not shown) acting to apply a braking action to the king pin by which the tractor and trailer are articulated. The other inlet of the double check valve 16 is fed, optionally via a manual cut-out valve 30, from the outlet of a relay valve 14, via line 15. Valve 14 is fed from a reservoir 11, associated with the emergency line, via a pressure-reducing valve 13 which provides a predetermined pressure, e.g. 40 1bs. per square inch. Whenever a significant pressure exists in the service line, relay is actuated since its control chamber communicates with the service line via line 18. The predetermined pressure is then applied to the double-check valve 16, and the actuator 10 is fed with this pressure so long as pressure in line 7 is less than this. When pressure in line 7 is greater than the predetermined pressure actuator 10 is then fed with the higher pressure, since valve 16 responds to whichever pressure is the highest. An additional control valve 20 may be provided which is arranged to be actuated whenever relative angular movement between tractor and trailer portions exceeds a predetermined amount, whereby a fixed pressure is supplied by reservoir 11 by way of a second pressure-reducing valve 22 and a second double-check valve 24 to the actuator 10, regardless of whether or not pressure exists in line 6 to actuate the valve 14, the actuator 10 then responding to whichever of the three pressures (in lines 6, 15 and 23) is the highest.
