Title: Improvements in and relating to multi-channel electric pulse signalling systems
Inventor: LEVY MAURICE MOISE
IPC: H04J3/00
Filed: 1948-12-03
Abstract: 663,782. Multiplex pulse signalling. GENERAL ELECTRIC CO., Ltd. Jan. 3, 1950 [Dec. 3, 1948], No. 31380/48. Class 40 (v). In a multi-channel pulse communication system, each channel comprises a valve producing broad amplitude modulated pulses, the valves being arranged in groups with a common output and the outputs being associated with means for selecting a narrower portion of each pulse the resulting narrow amplitude modulated pulses being interlaced for transmission. The pulses may be converted to time or duration modulated pulses before transmission. In the embodiment described, which accommodates eighty channels, eight cathoderay distributers are used, of the type described in Specification 619,785, of which each provides ten of the channel valves. Each distributer has a common cathode which provides an electron beam which is magnetically rotated to serve each valve in turn. Four of these distributers D1 ... D4, are shown in Fig. 1, the common anodes A1 ... A4 respectively being connected to gating devices M1 ... M4 respectively. The signals from channels 1, 9, 17 ... 65, 73 are applied to the grids G1 of distributer Dl, the signals from channels 2, 10, 18 ... 66, 74 to grids G2 of distributer D2 and so on, and the electron beams B1 ... B4 rotate in synchronism under the control of quadrature deflecting oscillations from a generator Q, Fig. 3. The beams of distributers D5 ... D8 (not shown) are controlled from terminals Q1, Q2 of generator Q and rotate in synchronism but in such a phase that the broad amplitude modulated pulse outputs O, O<SP>1</SP>, Fig. 2, from the two sets of distributers interlace in time. For convenience these superposed channel pulses are shown of constant unmodulated amplitudes. The gating circuits M1 ... M4 are controlled by narrow pulse trains GP1 ... GP4, Fig. 2, respectively, applied to terminals TG1 ... TG4, and pulse trains GP5 ... GP8 are applied to the other four gating circuits, not shown. The resulting interlaced narrow amplitude modulated channel pulse trains are fed to a common output terminal TO. The gating pulse trains are derived from tappings TG1 ... TG8, Fig. 3, on a delay line DL fed with pulses from a generator PG which, with the generator Q, is controlled by a synchronizing oscillator SS. In a modification, the gating functions are all performed by a further cathode-ray distributer of the same type, to the eight grids of which are connected the common anodes Al ... A8, Fig. 5 (not shown). The amplitude modulated pulses may be converted into time or duration modulated pulses by a known type of cathoderay tube modulator, Fig. 6 (not shown). Other arrangements are described in which the distributers D1 . . . D8 are replaced by gated pentode valves.

Title: Control valve
IPC: B60T8/26
Filed: 1973-07-03
Abstract: 1416209 Brake pressure proportioning valve WAGNER ELECTRIC CORP 3 July 1973 [3 July 1972] 31550/73 Headings F2F and F2V A brake pressure proportioning valve has means such as a piston 15 movable in a housing 2 to reduce fluid pressure in a first predetermined ratio in response to an inlet pressure less than a first predetermined value and in a second predetermined ratio when the inlet pressure is greater than the first predetermined value but less than a second predetermined value, and a caged resilient means such as a spring movable with the proportioning means and co-operable with an abutment so that when the pressure exceeds the second predetermined value and overcomes the inherent force of the caged spring free flow is allowed between inlet and outlet. As shown a piston 15 has a valve seat 20 normally engaged by a spring urged valve member 21 which also engages an exhaust valve seat 12. A piston 24 is urged by a spring 25 caged between the pistons 15, 24. As inlet pressure increases the concerted movement of the pistons disengages seat 20 from valve member 21 to establish metered communication between inlet and outlet ports 10, 14 respectively and when the inlet pressure lies between the predetermined values piston 15 is moved further to effect a metered increase in the output pressure. Upon a pressure increase to exceed the second predetermined value piston 24 is urged upwardly into a disabled position abutting a stop 8 and piston 15 moves downwardly to provide an open or non-proportioning flow between the inlet and outlet ports. When the desired braking effect has been attained the input port is vented to atmosphere which eliminates the pressure on piston 15 which can then move upwards so that member 21 allows venting to atmosphere via port 13.
