Title: Improvements in or relating to theft alarm systems for automobiles
IPC: B60R25/10
Filed: 1948-09-15
Abstract: 673,940. Burglar and like alarms. GRAY, A. R. Sept. 15, 1948. No. 24185/48. Class 118 (i). [Also in Group XIX] A theft alarm for road vehicles comprises a mileage counter adapted tc close alarm contacts upon a predetermined distance being travel led by the vehicle after setting the de vice. A mileage cylinder 11 is slidably carried on a square shaft 12 and its toothed rim 13 is urged out of contact with a gear train 14, 15, 16, 17  by a spring 26. An annular cam surface 20 gradually rises from the rear face of the toothed rim 13 and ends in an abrupt radial step 22. An arm 31 is adapted to engage the cam surface 20 when the cylinder 11 is rotated and move the cylinder so that rim 13 engages the gear wheel 14, spring 34 (acting on the arm 31) being stronger than spring 26. By depressing knob 33 against spring 34 the arm 31 is moved back to allow cylinder 11 to be freely rotated by knob 29 which is set to a chosen mileage by the aid of a scale on plate 70 as in Fig. 5 (not shown). On releasing knob 33 the arm 31 presses on cam 20 to move cylinder 11 into engagement with the gear train and when the vehicle is subsequently moved the cylinder 11 is slowly rotated by a cable drive 18 which may be coupled to the speedometer cable as in Fig. 3 (not shown). When the end 22 of the cam 20 passes the arm 31 the cylinder 11 suddenly moves axially under pressure of spring 26 and disengages rim 13 from the gear train, at the same time bridging alarm contacts 40, 41, by a conductive insert 23 in an insulator portion 24 of the cylinder 11. Contacts 40, 41 close circuits from the vehicle battery to a solenoid Fig. 4 (not shown) which interrupts the ignition circuit and to audible and visible alarms and via a bimetallic thermal flashing device. The device will operate if the vehicle is towed without the engine running, and may be set for a very short distance so that the alarm is given almost immediately the vehicle is moved. Sufficient space is provided between the step 22 and commencement of the cam 20 to allow the cylinder 11 to be set at an "off" position in which the insert 23 is clear of contacts 40, 41 but the rim 13 is not pressed into engagement with the gear train. A reset button for restoration of the ignition circuit is also provided on panel 70 and the device is mounted in a lockable compartment on the dashboard or other convenient position.

Patent GB-337847-A (GB)
Title: A process for working up oxides of nitrogen
IPC: C01B21/26
Filed: 1929-08-13
Abstract: 337,847. Caro, N., and Frank, A. R. Aug. 13, 1929. Drawings to Specification. Nitrogen tetroxide or nitric acid in concentrated form is obtained from mixtures containing nitrogen oxides, oxygen, and water vapour, such as ammonia combustion mixtures, by a three phase process in which part only of the water is first removed avoiding any considerable oxidation, the residual water is separated after or during the oxidation, which is promoted by lowering the temperature, as a tetroxide containing nitric acid of low water vapour pressure, and in the third phase the gas may be cooled or treated with substances which lower the vapour pressure of the tetroxide or have absorbing properties. Dispersed and dissolved substances, such as nitric or nitrous acids, solvents or solid adsorption agents such as silica gel are suitable. The gas may be liquefied or solid nitrogen oxides frozen out, and the treatments may take place in stages. The nitrogen tetroxide removed may be added to the liquefied gas or to the crude mixture from the second phase. This crude mixture can be worked up to give a 98 to 100 per cent tetroxide-free acid by treatment with oxygen at increased pressure and increased temperature. The amount of water passing to the second phase may be sufficient to allow the condensates from the second and third phases to be combined or employed for the mutual irrigation or scrubbing and adsorption. The residual gas may be compressed and washed with the condensates from the second or third phases, or the compressed gas from the second phase may be treated with condensate from the second phase. The second and third phases may be combined. Part or the whole of the plant may be run under increased pressure. The waste gas may be washed with water from the first phase to obtain aqueous nitric acid. With mixtures obtained by combustion of ammonia with pure oxygen the discharge temperature of the first phase may be above 100‹ C.; when air is used the temperature may be only 45‹ C., the conditions for the other phases varying similarly. The residual gas of the condensation can be worked up to nitrogen or oxygen. Specification 290,679 is referred to.

Abstract: 1414061 Pump driving arrangements; gear-pumps A D TOOTH and L J FORDHAM 24 May 1973 [2 June 1972 14 Nov 1972] 24807/73 Headings F1A and F1F [Also in Division F2] A pump, e.g. for operating a vehicle tipping jack hydraulic system, is driven via a clutch which is normally biased into its disengaged position and is initially engaged, e.g. by a mechanical linkage, to start the pump, and is held engaged by hydraulic means energized by the pump output so long as the hydraulic system is pressurized, means being provided to depressurize the system. In Fig. 4, a gear-pump 52 has a shaft 53 driven by a pulley 67 when the pulley is moved to the right to engage a clutch plate 65 keyed to shaft 53, the pulley being moved initially by mechanical means, and then held in engagement by pump output pressure acting on piston 85 via passage 88. A spring 68 disengages the clutch when the pump system is depressurized. In Fig. 3 (not shown), the gear-pump assembly is axially movable in its casing by its output pressure and moves the drive-shaft and clutch plate to engage the pulley. In Fig. 1 (not shown), the whole pump (1) is movable to engage a drive flange (6) on its shaft with a clutch plate (22), and at the same time causing disengagement of the clutch plate from a pulley (10), e.g. connected to an engine auxiliary.. In Fig. 2 (not shown), an annular piston (39) acts to move a spring-loaded pulley (34) against a clutch plate (31). In Fig. 5, the pump 94 supplies actuating liquid from a sump 91 to a jack 89 via a control valve 93. Valve 93, Fig. 6, comprises a threaded bobbin 100 which is movable to connect the pump output, at port 109, to the jack, at port 110, via bobbin passage 108 and check-valve 105. When the jack piston has reached its required position, bobbin 100 is moved to the right to connect pump output port 109 to sump port 111, check-valve 105 then closing to lock the jack piston in position, and due to depressurizing of the pump output by its connection to the sump, clutch 96 disengages to stop the pump; such depressurizing also may be effected by valve 112. To effect return of the jack piston, bobbin 100 is moved further to the right to lift valve 105 off its seat, thereby connecting the jack to the sump via bobbin passage 108 and port 111. A pressure relief valve 92 is provided.
