Abstract: 1385572 Pressure regulating valves; valves NISSAN MOTOR CO Ltd 8 Nov 1972 [13 Nov 1971] 51497/72 Headings F2F and F2V A fluid pressure control device for a motor vehicle braking system comprises a housing 40, formed with a bore 46 sealed from a cavity 42 divided into chambers 59, 61 by an annular sealing member 58 attached to the cavity wall, a first inlet port 76 opening into chamber 59 and a second inlet port 48 opening into the bore 46, and a plunger 50 extending with radial clearance through an aperture 60 in the sealing member 58 and having an annular projection 52 disposed in the chamber 61 and engageable with the sealing member against the bias of a spring 62. As shown, inlet port 76 is connected to a line 14 leading from a split master cylinder 10 to front wheel cylinders 20, 20<1> and port 48 is connected to an auxiliary line 16 leading from the master cylinder 10 to front auxiliary cylinders 26, 26<1>. Up to a critical fluid pressure, fluid from the master cylinder 10 passes via inlet port 76, aperture 60 and outlet port 78 to rear wheel cylinders 34, 34<1> unregulated as the combined upward forces on the plunger 50 of spring 62 and pressure acting in bore 46 on plunger reduced and portion 54 bias annular projection 52 away from the seal 58. At this critical pressure, the downwardly acting fluid pressure on the plunger causes the projection 52 to engage seal 58. Thereafter the pressure at outlet port 78 is regulated as the inlet pressure increases. If the auxiliary line 16 fails the pressure acting in bore 46 on plunger end portion 54 is correspondingly lost so that the critical pressure is altered. It is stated that instead of being a pressure proportioning valve as shown the device may be a pressure limiting valve.

Abstract: 1,130,080. Hollow fuel cell electrodes. COMPAGNIE GENERALE D'ELECTRICITE. 18 Nov., 1966 [10 Dec., 1965; 27 April, 1966; 11 July, 1966; 11 Oct., 1966], No. 51743/66. Heading H1B. A fuel cell electrode comprises two parallel electrically conductive porous plates (1) separated along their periphery by an annular plastics material packing (2) of substantially T-shaped radial cross-section, said plates being fixed on either side of the leg of the T, forming a fluidtight chamber, said packing comprising at least one radial passage (10) for the supply of gas to the chamber, and a current-collector being in electrical contact with at least one of the plates. The current collector may be of a comb type (12) or a helical wire having its axis parallel to the plates and compressed between them, connected to a wire (5) leading through the packing in a fluid-tight manner. The porous plates (1) may be separated by spacing members of a plastics material, preferably in the form of annular elements having radial passages (8) providing communication between the annular chambers formed thereby. In a preferred embodiment a metal tube (15) connects the gas supply passage through the spacers to the central chamber, and a gas discharge passage passes through the packing from the peripheral chamber. The packing preferably also contains passages (4) parallel to the axis of the packing, preferably in portions (3) having a radial dimension greater than the average, some serving as means for supply and discharge of gas, into which the appropriate radial passages (10) lead, and others as passages for assembly rods for stacking the cells. In a bipolar form of the cell a gas-impermeable metal plate lies in the central plane of the packing and cell, defining two fluid-tight chambers; these are each fitted with current collectors, gas supply means and spacers as above, and each porous plate is in electrical connection with the central plate. One or both ends of the cross-bar of the T may extend beyond the level of the porous plate, thus permitting adjacently disposed cells to define a fluid-tight chamber for the electrolyte. Further passages through the packing communicate with these electrolyte chambers, allowing supply and discharge of electrolyte when the cells are stacked to form a battery. Figs. 6 and 7, to which the above reference numerals relate, show a simple form of a cell according to the invention in plan and transverse sections.

Abstract: 1405154 Teleprinter line monitoring; time delay circuits SIEMENS AG 10 Nov 1972 [24 Jan 1972] 51907/72 Headings H4P and H3T A time constant in the control circuit of a teleprinter line-monitoring relay K is switched to any one of four possible values by a contact k of the relay in association with diodes D5-D7. This ensures that a positive polarity on the line E must last long enough to initially energize the relay, and that thereafter a negative (clear) polarity must last long enough to de-energize it. Relay K is thus not energized by spurious positive levels nor by negative signalling levels. Assuming k to be open (as shown) and D5 therefore connected to a point A in the series connection of four resistors R12-R15, the timing capacitor C is charged to - 60 v. through the path R12, D6, R15. Should the line E now go positive, bi-stable transistors T1, T2 turn off and T3 truns on to provide a discharge circuit from + 60 v. through D5, D7 R13, R12, the time constant with R12+R13 being much greater than the previous one R12+R15. This ensures that E must remain positive long enough to raise point D high enough for bi-stable transistors T4, T5 to conduct and turn on T6. If E is not high for long enough, R12+R15 rapidly charge C again to - 60 v. When K has operated however, k connects D5 to point C, and the discharge circuit for capacitor C to +60 v. through T3 includes only R12, whereas the charge circuit to - 60 v. includes all four resistors. Hence a long negative level on E is required for C to charge negatively enough to turn off relay K, while R12 rapidly discharges C to + 60 v. after any negative E level of insufficient duration.
