IPC: D21F5/02
Filed: 1960-06-23
Abstract: 919,772. Drying paper. SULZER FRERES S.A. June 23, 1960 [July 17, 1959], No. 22030/60. Class 96. [Also in Group XIII] The drying section 1 of a paper-making machine comprises a travelling felt and a closed hood 2, in which warm exhaust air is collected. This air is passed through a pipe 3 and a heatexchanger 4 to heat water stored in a tank 7. The exhaust air then passes through a pipe 14 and a heat-exchanger 15, in which it heats fresh air entering through a pipe 16. The heated fresh air passes, through a pipe 17, a fan 18 and a heater 19, into the base of the drying section to serve as below-felt drying air. Exhaust air from the heat-exchanger 15 is discharged into the atmosphere through a pipe 23 and fan 24. A pipe 10, incorporating a valve 11, connects the pipes 3 and 14 to by-pass the heat-exchanger 4. A pipe 22, incorporating a valve 21, connects the pipes 14 and 23 to by-pass the heatexchanger 15. The valve 11 is actuated by a servomotor 13 controlled by a thermostat 12 in the heated water. The valve 21 is actuated by a servomotor 26 controlled by a thermostat 25 in the heated fresh air entering the drying section. When the temperature of this air falls below a predetermined value, the thermostat 25 overrides the control exerted by the thermostat 12 to limit the extent to which the valve 11 can be closed.

Abstract: 904,591. Control of D.C. motors; controllers. ELECTRO DYNAMIC CONSTRUCTION CO. Ltd., TIMBERLAKE, E. J., and FELTBOWER, B. Oct. 13, 1958 [July 12, 1957], No. 22188/57. Class 38 (3). A controller for an electric motor comprises a carbon pile 5 having an insulating disc 57 at each end, one disc abutting end-plate 52 whilst the other lies adjacent to pressure plate 58. A light spring 59 provides initial pressure for maintaining the carbon discs in contact. A spring-housing 62 engages both a shock-absorber spring 64 and an actuator cam 65 forming part of motion-transmitting lever 69. Rod 77 is screwed into housing 62 and carries nut 78 engaging spring 59 as well as a backstop nut 79 against which the outer face of cam 65 is pressed. The lever 69 forms part of a transmission system comprising shock-absorber spring 85 and hydraulic delay device 86, and which is operated by Bowden cable 87a. When force is applied to pull-rods 90, the spring 85 is compressed and transmits the pull to piston-rod 95, a sudden pull being absorbed by the controlled flow of oil past a needle valve which delays the force applied to lever 69 to which rod 95a is linked. When the cable 87a is actuated to compress spring 85 and apply pressure to pile 5, actuator 115 moves away from switch 1LS so energizing a contactor MC for establishing the motor circuit. At maximum pressure of the pile, actuator 116 operates switch 2LS for short-circuiting the pile. On the return stroke oil in the right-hand side of cylinder 105a passes through relief holes in piston 105, opening valve 104 against spring pressure to provide a by-pass for the needle valve and to allow a quick return motion of the piston-rod 95. Specification 904,592 is referred to.

Title: Improvements in signalling systems
IPC: G01S7/282
Filed: 1948-08-27
Abstract: 691,294. Pulse shaping circuits; radio navigation. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES. Aug. 27, 1948 [Feb. 19, 1948], No. 22693/48. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 11, 1949.] Classes 40 (vi) and 40 (vii). The position in time of a rounded pulse is determined by deriving a pulse which occurs at a fixed fraction of the maximum amplitude, e.g. at half-amplitude. Two voltages are derived by means of networks, one of which contains a rectifier and are combined to provide the input voltage to an amplifier having a rapid rate of change at the desired instant, the output voltage from the amplifier being fed to a differentiating circuit. The circuit is particularly applicable to radar systems and may be employed in a rotating beam navigation system. Pulse shaping circuits. Pulse a, Fig. 2, is fed from a tapping 17, Fig. 1, over resistor 24 to the grid of normally non-conducting valve 15, and also to a phase inverter 26 feeding a diode 27, which conducts to cause a potential b to be developed at the anode. The resulting grid potential of valve 15 has the waveform shown at c which causes the cut-off axis at half-amplitude of curve a since curve b is arranged to have half the peak amplitude of curve a. The pulse appearing at the anode of valve 15 is differentiated by circuit 30. In a modification, Fig. 3 (not shown), a series circuit of a diode and capacitor is fed with the input wave and is mixed with it to produce a similar wave at the grid of valve 15. In a further modification, Fig. 5, pulse a, Fig. 6, is applied from valve 40 to the mixing resistor pad 41 together with a wave b derived from rectifier 44 so that a composite wave c is applied to valve 45. After amplification in valves 45, 46 the wave appears as at d, Fig. 7, and after rectification e. The wave is then differentiated over capacitor 48 and resistor 49 to produce a pulse f and output pulse g. The Specification as open to inspection under Sect. 91 also describes the application of the circuits to radar responder beacon and hyperbolic navigation systems. It may also be employed in multiplex systems using positionmodulated pulses, and in systems using light or sound pulses. This subject-matter does not appear in the Specification as accepted.
