Patent GB-936603-A (GB)
Title: Brake pressure control
IPC: G05D1/00
Filed: 1961-12-04
Abstract: 936,603. Fluid brake control. GOODYEAR TIRE & RUBBER CO. Dec. 4, 1961 [March 21, 1961], No. 43234/61. Class 103 (1). A brake pressure control for manually operated fluid brakes 6, 7 comprises a pressure control valve 5 the output pressure of which is a function of the current supplied to its operating circuit and a control circuit for valve 5. The control circuit includes a velocity detector 1, driven by the wheel W to be braked, giving an electrical power output which drives an acceleration detector 2, the output of which is amplified to energize the operating circuit. A variation detector 8 and a variable bleeder means 3 are each connected in parallel with the amplifier 4 to bleed off restricted amounts of current from the acceleration detector 2 but on a sharp increase in current due to a rapid deceleration of the wheel W the bleeding is reduced. The velocity detector 1 may comprise a D.C. power generator and the acceleration detector a capacitor. The base of transistor 21 of the bleeder means 3 is biased from a 24 V. D.C. supply through a variable resistance network which includes a Zener diode 31. The variation detector is connected to the output side of amplifier 4, a pump circuit comprising capacitors 28, 34 and junction diodes 29, 129 increasing its potential with every pulse from the amplifier. Pulsing is caused by a sequence of brake applications and automatic releases at the onset of too great a deceleration of the wheel. The build-up of potential biases the base of bleeder transistor 21 against conduction. Two further circuits are described in which the bleeder means is connected to the link between the two transistors in the amplifier and the output of the amplifier respectively. Specifications 705,233 and 769,659 are referred to.

Abstract: 1,236,926. Spectro-photometers. PERKINELMER Ltd. Sept.24, 1968 [Sept.29, 1967], No.44404/67. Heading G2J. A gas cell for infrared spectro-photometry comprises a rectilinear light guide 1 having a goldplated specular inner surface defining a gas duct, an image-forming mirror 2 closing one end of the light-guide, the other end of the duct having an entry aperture 4 and exit aperture 5 for the infrared radiation, the apertures being optically conjugate whether the radiation is internally reflected off the specular surface or not. Preferably the apertures 4, 5 are located side-by-side in the same plane transverse to longitudinal axis of the light-guide. Opposed windows 3 perpendicular to the apertures are formed in the sides of the guide 1 and incident radiation is reflected of a front-coated 90 degrees prism 7 to pass entry aperture 4. Similarly the radiation then reflected from mirror 2 to exit aperture 5 is deflected by a second surface 9 of said prism. Preferably the radius of curvature of mirror 2 and the location of entry and exit apertures are arranged to give a magnification of 1:1. The cross-section of the duct is rectangular. It is preferred that the gas cell be vertically located in a spectro-photometer although it may be constructed for horizontal location. In alternative embodiments the entry and exit apertures are formed in opposed parallel planes located in the sides of the light-guide, parallel to its longitudial axis, a 90 degrees prism still being required to form a radiation path between the apertures via the mirror, or the apertures may be directly formed in the said end wall of the light-guide. The mirror 2 may be spherical or cylindrical and either or both windows for the apertures may be positive or negative lenses. Gas to be analyzed is caused to flow along the length of the duct. A detailed construction of a gas-cell is given with reference to Fig. 9 (not shown).

Abstract: 1,244,073. Turbines; lubricating bearings. MESSERSCHMITT-BOLKON-BLOHM G. m.b. H. Sept.12, 1969, No.45086/69. Heading F1T. [Also in Division F2] A bearing 4 for a gas turbine shaft in a liquidfuelled rocket includes a liquid seal (e.g. mercury) in a gap 6 of higher specific gravity than the lubricant, the arrangement being such that lubricant flowing to the bearing is forced against a surface of the liquid seal to cause a direct heat exchange between the liquid seal and the lubricant and a consequent cooling of the seal. Blades 11 in the chamber act on the mercury in the gap 6 and balance the gas pressure in the gap 5 between the turbine rotor 2 and stator. The lubricant passes through a non-return valve 14 and is forced against the inner surface of the ring of mercury in the gap 6 causing the direct heat exchange to take place; the lubricant then cools the seal arrangement further as it passes through an annular gap 17 into a chamber 18 which accumulates and retains the lubricant in the vicinity of the seal until the pressure is sufficient to lift a valve 19 off its seat 20 and allow the lubricant to pass to the bearing 4.

An electrical conductor core 10 is given a relatively thin conducting covering 14 at an extruder (12), Figs. 1 and 2 (not shown), and is then passed through a second extruder 16 to receive a relatively thick insulating covering 18 and simultaneously a further relatively thin conducting covering 20. The covering materials may be curable butyl rubber or ethylene-propylene polymers, but are preferably of cross-linkable polyethylene, the conducting layers being suitably loaded with carbon black. Extruder (12) has an exchangeable die (35) centred by screws (42). Extruder 16 is spaced downstream of extruder (12) to allow sufficient cooling of covering 14 before it passes through die 55.
