Abstract: 767,998. Vehicle windows. HALLAM, SLEIGH & CHESTON, Ltd. Sept. 12, 1955 [Sept. 11, 1954], No. 26362/54. Class 20(3) A ventilation window 1 for the driving cab of a lorry, or truck, pivoted at points intermediate front and rear edges of the window by means of top and bottom pivot pins 5, 6 has a rubber weather excluding sealing strip, or frame 12, a narrow groove 13 in the outer edge of the frame being engaged by the edge of a body panel 2 bounding the window opening, and the inside edge having a pair of flanges 14, 14a against which a glazing frame 7 engages when the window is closed. The flanges 14, 14a are located respectively toward the inside and outside of the vehicle, the flange 14 extending rearward, and the flange 14a forward, of the pivots 5, 6, and the frame 12 comprising two lengths of reversed sections with their ends joined adjacent the pivots pins 5, 6. The latter engage respectively within bearing sleeves 8, 9 fixed to the glazing frame 7, the pin 5 having a part 24 which is bolted, with a packing member 25, to the outer face 10 of the body panel 2, and the pin 6 being carried by a casing 15 secured by bolts 53 to the inside face 11 of the panel 2. The pin 6, riveted at 26 to the bearing sleeve 9, and to a bushing 9a secured to the frame 7, rotates with the window as the latter is moved. The pivots 5, 6 are slightly inclined to bring them into approximate axial alignment. The window is held in a predetermined angular position by means of a toothed wheel 17 which is fixed to the lower end of the pin 6 and co-operates with teeth 23 on detent plates 19 which are housed in the casing 15 and are urged into contact with the wheel 17 by means of rubber blocks 18. Hand pressure on the window 1 overcomes the resistance afforded by the co-operating teeth so that the teeth 23 ride over the periphery of the wheel 17 while the window is being moved. The casing 15, initially open at the underside to admit the blocks 18 is closed by a cover plate 27. The window can be moved by a handle 30 which is pivoted to the frame 7 and is arranged to engage a striking plate 31 carried on a bracket 32 bolted to the panel 2. In a modified form of detent device the rubber blocks are omitted the toothed wheel 17 being engaged by sheet metal detent units having resilient side arms which urge them into engagement with the wheel 17. In a further modification, the pivot pin 6 carries a boss having concave peripheral notches which engage spring pressed balls contained within tubes fixed inside the casing 15. In the modification, Fig. 8, the toothed wheel 43 is surrounded by a split rubber collar 46 which is itself surrounded by a metal casing 47. The arrangement is fitted to a rail, not shown, which is secured to the panel 2.

Filed: 1960-07-30
Abstract: 903,576. Determining the moisture content of steam. VYZKUMNY USTAV ENERGETICKY PRAHA. July 30, 1960, No. 26622/60. Class 97 (3). Steam passing through a conduit is induced by means of an injector to enter a dete ctor 1, Fig. 2, or controlled in its entry by means of a valve, not shown, at the exit 9 of the detector 1, according as the pressure of the steam is less than or greater than atmospheric, the detector having means 2a, 6a for measuring the initial pressure, P0, and temperature t0, (not marked) a heater 8 for bringing the moist steam to a stage of superheat, means 2b, 6b for measuring the pressure P1, and temperature t1, at this lower superheat, a further heater 8 for raising the steam to a stage of higher superheat and means 2c, 6c for measuring the pressure P2 and temperature t2 at this higher superheat. The ratio Q 1 /Q 2  of the   heat inputs to the two heaters 8 is measured by an instrument 12 and it is shown in the Speci-   fication that #i 1  =Q 1 /Q 2  #i 2 , where #i 1  and   #i 2  are the differences in enthalpy from moist steam to the lower degree of superheat, and from the latter to the higher degree of superheat, respectively. From the graph, Fig. 1, of enthalpy i against entropy s, the position C of higher degree of superheat is readily found from a knowledge of P2, t2. Similarly position B corresponding to lower degree of superheat, P1, t1 can be determined and thus the value of #i 2  read off. On calculating the value of #i 1  and knowing the value of P0, the position A is determined from which the moisture content X0 can be read off. The pressure of the steam outside of the detector may be measured by means 4 to ensure that it is the same as that P0 inside. The apparatus may be used for controlling the moisture content of steam.

Abstract: 984,755. Auto pilot systems. S. SMITH & SONS (ENGLAND) Ltd. July 12,1963 [July 13, 1962], No. 26951/62. Heading G3R. [Also in Division H4] An aircraft is provided with an auto pilot system whereby it is guided on to and along a desired radial of a VOR beacon. In the system a VOR receiver 52 produces signals indicative of the angular difference # between the bearing of the desired fly-in radial of the beacon and the radial of the beacon in which the aircraft is actually situated. These signals are processed in a mechanical filter system, described in Specification 984,754, to produce from transformer 74 an auto pilot control signal representing where #f is a function given by transfer function # f  = #/(1 + kTD) the term kT varying non-linearly as described in the above Specification, # is the bearing of the aircraft and #T is the bearing of the desired radial. The term (# -#T) is supplied by a flight compass system 72. The auto pilot control signal being in the form of an amplitude modulation on a 400 c/s carrier, is first passed via a switch R15 to a demodulator 75. The demodulated signal is passed to a signal summing circuit 76,which forms part of a servo system for controlling the position of shaft 78 in accordance with a variable #d representing a demanded bank angle for use in controlling the aileron of the aircraft. The angle #d is given by The output of the summing circuit is passed to a servo amplifier 77 which produces an output energizing a servomotor 81. This servomotor turns shaft 80 and shaft 78 via gears 79,to drive a potentiometer 83 and feed a signal back to the input of the summing circuit representing the angle of the shaft 80. The rate of rotation of the shaft 80 is also measured by a tachometer generator 82,to produce a second feedback signal to the summing circuit. Shaft 78 drives the rotor of a synchro transformer 86 having a stator winding energized by signals from vertical gyroscope equipment 87 representing the actual bank angle # of the aircraft. The output of the synchro transformer represents the difference between the actual bank angle # and the demanded bank angle #d. This output is fed to auto pilot aileron channel 91,together with signals from potentiometer 83 and a rate gyroscope unit 94,which provides a measure of the aircraft's rate of bank D#. The auto pilot aileron channel then produces a rate of aileron movement signal (D#)d given by:  where F 1 ,n 3 ,# 1 ,# 2 ,# 3 ,# 4 ,# 5  and # 6  are constants. The system also comprises an arrangement whereby the output of the VOR receiver is earthed when the aircraft is within the cone of confusion of the beacon, (see Division H4).
