IPC: F25J3/08
Filed: 1924-10-31
Abstract: 234,041. Soc. l'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. May 15, 1924, [Convention date]. Separating gaseous mixtures by liquefaction.- In the manufacture of hydrogen by partial liquefaction of gaseous mixtures containing it, such as coke oven or illuminating gas, the final washing of the compressed hydrogen, to remove carbon monoxide, before expansion is effected by liquefied nitrogen intended for the lubrication of the hydrogen expansion engine. The nitrogen after cooling in temperature exchangers may be cooled in tubes cooled by the gaseous carbon monoxide issuing from the vaporizer and is then intensely cooled in tubes situated in the engine exhaust. The liquid nitrogen thus cooled to near solidification is passed into a rectifying column wherein it washes the hydrogen. Sufficient nitro. gen may be used to allow excess liquid nitrogen to remain with the condensed carbon monoxide, while the vaporized nitrogen mixes with the hydrogen and liquefies in and lubricates the expansion engine. Specifications 174,327 and 175,605 are referred to.

Title: Improvements relating to apparatus for locating a datum position
IPC: G01D5/36
Filed: 1964-06-25
Abstract: 1,014,405. Measuring displacement photoelectrically. FERRANTI Ltd. June 25,1964 [June 27,1963], No. 26236/64. Heading G1A. In apparatus for measuring the relative displacement of two movable bodies by means of crossed gratings, an arrangement is provided for the location of a datum position from which to count the fringe patterns representative of the relative displacement. The arrangement comprises a glass member 14 attached to a housing 10 which is connected by a link 12 to one of the relatively movable bodies of e.g. a machine tool or like apparatus, and a similar glass member 20 attached to the other body through a link 22. The housing 10 has two pairs of apertures 16 and 18. In line with the apertures 16 the glass members 14 and 20 carry complementary patterns (as shown in Fig. 3), and opposite the apertures 18, they each carry a plurality of closely spaced parallel opaque lines i.e. the gratings, the complementary patterns comprise on one member a pattern of alternatively transparent and opaque areas and on the other a negative image of the same pattern, such that when the two are accurately aligned in the datum position, light from a source 28 is completely cut off from the photo-cell 30. AT any other position than this light reaches the photo-cell and so, on alignment of the patterns, the photo-cell can be adapted to trigger the counting mechanism. The source-detector system may be carried on the housing 10 so as to move with it. The patterns may have equal widths and spacings of dark and light areas, but are preferably non-repetitive. A number of patterns may be spaced along the member 20 (in direction of movement of the bodies) to provide a number of datum positions. Sensitivity of the apparatus depends on the width of the smallest dimension of the pattern and on the number of transparent and opaque areas in the field of view of the detector. Movement in more than one direction in a plane may be measured by provision of special patterns.

Title: Improvements relating to optical sighting devices
IPC: G02B23/10
Filed: 1946-08-31
Abstract: 619,891. Sighting devices. FERRANTI, Ltd., and SPENCER, L. J. Aug. 31, 1946, No. 26241. [Class 97 (i)] A sighting device comprises two or more semi - reflecting plates through which the target is viewed and by which two or more images of a graticule are formed superimposed on the object sighted, the graticule being positioned outside the field of view. As shown in Fig. 1, a housing a encloses semi-reflecting plates g1, g2, a collimating lens f, a graticule d and a lamp e, the plates serving to form two images of the graticule and allowing observation of the target. The observer can thus keep an image of a graticule in sight if he moves his head upwards in a direction at right angles to the axis of the branch b of the housing. In order that the - observer can move his head in this direction and also in a direction orthogonal thereto, a semi-reflecting plate i may be interposed between the plate gl and the lens f as shown in Fig. 3. Part of the light is reflected at i to a mirror j so that four graticule images are formed by the plates gl, g2. The number of plates g1, g2 may be increased and more semireflecting plates may be disposed between the plate i and mirror j. Specification 578,958 is referred to.

Abstract: 665,800. Fluid-actuated valves. BENDIX AVIATION CORPORATION. Oct. 17, 1949 [Nov. 29, 1948], No. 26643/49. Class 135. A valve for automatically effecting sequential operation in one direction, and simultaneous return movement, of hydraulic jacks 1, 2 comprises a spring- loaded piston valve member 24 normally permitting flow between ports 18, 19 but preventing communication between ports 16, 18. When a control valve 5 is set as shown, pressure liquid passes from a pump 4 to a conduit 14 common to both jacks 1, 2 whose pistons commence to move downwardly and to the right respectively, exhausting liquid through conduits 15, 17. The liquid exhausting through the conduit 15 urges the valve member 24 to the right, allowing the liquid-to pass through the port 18 to a reservoir 3 but stopping the exhaust of liquid from the jack 2. Thus, the jack 1 completes its movement before the pressure in the conduit 15 falls to allow the valve member to return to normal position and permit the jack 2 to be operated. When the valve 5 is set to return the jacks, the conduit 14 is connected to a pipe 21 discharging into the reservoir and the pump delivers liquid through a check valve 6 to the jack 1 and through the ports 18, 19 to the jack 2. The valve member 24 remains in the position shown, since both ends of it are subjected to the pump pressure, the right-hand end through a passage 35.

Title: Safety valves
IPC: B60T17/22
Filed: 1971-04-19
Abstract: 1352072 Valves; fluid pressure brakes AISIN SEIKI KK 19 April 1971 [9 April 1970] 26849/71 Headings F2V F2E and F2F In a hydraulic brake system (Fig. 4, not shown), a high pressure pump (P 1 ) is used to supply two accumulators (105, 110) which in turn are connected to two pedal-operated control valves (CV 1 , CV 2 ), the outputs of the two valves fed to the inputs 16, 16<SP>1</SP> of a pressure regulator 1 whose outputs 19, 19<SP>1</SP> are connected to wheel brake cylinders (W 1 , W 2 ). The circuit also includes a low pressure pump (P 2 ), an unloading valve (UV), a pressure intensifier (IN), and a power steering system connection (PS). The pressure regulator is also operatively connected to an alarm system (L 1  E 1 , L 2  E 2 ). The pressure regulator 1 comprises two identical valves 1a, 1b having a separator plate 2 interposed therebetween. Each valve includes a piston 6 which is formed with an annular tapering groove 14, a transverse flow passage 12 leading from the groove, a branch flow passage 13 leading from passage 12 toward the narrow end of the piston, and a working chamber 8 at the piston main end, the narrowest portion 4 of this piston 6 passing through a sealing arrangement 20. In operation and at small pressures within the input port 16, the piston 16 remains in the position shown whereat the input pressure fed to working chamber 8 via input branch line 28 is insufficient to displace the piston against spring 11. Accordingly, a maximum flow takes place between input and output ports 16 and 19, respectively, via an annular passage 15 formed around the main bore 3, the annular passage 14 and piston passages 12 and 13. With an increased input pressure corresponding to an increased pedal pressure, piston 6 moves leftwards as seen in the drawings, thereby varying the area of the flow path defined by the cooperating annular flow passages 15 and 14. Should the line downstream of output port 19 become fractured, the differential across piston 10 becomes such that piston 6 is displaced further to the left until annular flow passages 14, 15 are no longer in communication with one another. At this stage, a ball detent (25<SP>1</SP>, Fig. 3, not shown) engages an annular recess 24 in piston 6 and so prevents the latter from returning to the normal operating range. The fractured line is thus isolated from the input. With the piston so displaced, its portion 4 actuates one of the alarm circuits (L 1  E 1  or L 2  E 2 ).
