Title: Improvements in or relating to rail vehicle signal systems
IPC: B61L3/22
Filed: 1936-08-25
Abstract: 480,694. Railway signalling systems. LOWELL-WINTSCH AUTOMATIC TRAIN CONTROL, Inc. Aug. 25, 1936, No. 23334. Convention date, Aug. 26, 1935. [Class 105] Wayside and/or cab signals are controlled by rail current which can be regularly interrupted at such a rate that a slow pick-up relay remains dropped and a slow release relay remains up thereby to give one particular signal. A train in section D, Fig. 1, drops the track relay 6c the open front contacts 7c, 8c of which de-energize the slow release relay 12c and the slow pick up relay 11c. A back contact 14c of the relay 12c energizes the danger lamp R of the wayside signal for the section D. The back contacts 16c, 18c of the relays 11c, 12c, energize an interrupter motor 20c whereby interrupted current is fed to the rails of section C from a transformer T<1> by the intermittent closure at interrupter contact 23c of the primary circuit which includes a back contact 25c of the relay 11c. In section C this interrupted current causes the track relay 6b to vibrate but the period of each current application is not sufficient to lift the slow pick up relay 11b. The slow release relay 12b is however energized and remains up. A caution lamp Y for the section C is lit over a back contact 16b of relay 11b and front contact 27b of relay 12b. Sustained current is applied to the rails of section B by the front contact 29b of relay 12b, closing the primary circuit of the track feed transformer. This sustained current lifts both of the relays 11a, 12a front contacts 31a, 32a of which light the clear lamp G for the section B. Cab signals may be given by a similar arrangement of slow pick up and slow release relays controlled by a master relay which is operated by the rail current through inductive collectors or by the axle current as described in Specification 333,574, [Class 105]. Fig. 2 however shows an arrangement in which the interrupted alternating rail current passes to a traincarried collector device comprising a transformer core 37 conductively connected to the wheels and with a secondary winding 38 feeding a master relay 42 the intermittent energization of which causes, through a control relay 43, alternate flashing of two cab signal lamps R, G and an intermittent sounding of a whistle 61. A slow release relay 68 prevents a brake-valve magnet 67 being de-energized during such intermittent operation. Under danger conditions (all rail current shunted by an ahead train) the brakes are applied unless an " alert " key 74 is pressed to energize an auxiliary winding 75 for the relay 68. The key 74 at the same time causes a lamp B<1> to light up at a suitable point on the train to notify the passengers that the driver has acknowledged a restrictive signal.

Filed: 1961-06-29
Abstract: 926,496. Push-button retractive switches. DELMAN CO. June 29, 1961, No. 23532/61. Class 38 (5). [Also in Groups XXIII and XXXI] A delay-switch for a windshield cleaning device (see Group XXIII) operates a spray unit driven mechanically from the engine (see Group XXXI) as well as electrically-driven wipers. In the switch illustrated when a rod 112  is depressed a wire 72 of a Bowden unit 66 brings a pump unit (not shown) into contact with the engine fan-belt which causes liquid to be sprayed on to the windshield (not shown). Concurrently the necessary electrical contacts are made by a two-position switch 96 to switch on the wipers (not shown). At the same time a vacuum cup 170 is forced into contact with a bleed plate 174 and retains the switch depressed. Release of finger pressure from rod 112 allows a torsion spring (not shown) to bias the pump back into its inoperative position, which stops the sprayers. The wipers are kept operating until sufficient fluid from a chamber 164 bleeds through filters 180 and the bleedplate 174 to relieve the vacuum under cup 170. Spring 146 then returns the switch 58 to its initial position switching-off the wipers in so doing.

Abstract: 1, 067,271. Force measuring apparatus; transducers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 19, 1964 [June 14, 1963 \ No.23856/63. Headings G1N and G1W. A device for measuring thrust due to the rotation of a propeller comprises two coaxial, relatively axially movable members 4, 5 connected together in such a way by torsion bars 10, 11 whose longitudinal axes extend transversely of the axis of the movable members that the torsion bars 10, 11 so twist about their axes when the members are subjected to axial thrust that the amount of twist or the relative positioning of the axially movable members indicates the magnitude of the thrust. As shown in Fig. 2, a propeller 30 mounted on a rotatably and axially movable shaft 25 is connected to a rotatably but non-axially movable shaft 24 by the torsion bars 10, 11 each having one end connected to different projections (8 and 9), Fig. 1 (not shown), of the members 4 and 5 which are welded to the shafts 24 and 25 respectively and each having its other end gripped by a common member (14), Fig. 1 (not shown), arranged symmetrical about the axis of the members 4 and 5. The rotation of the shaft 24 is transmitted to the propeller shaft 25 through the movable members 4 and 5 via the member (14) and the subsequent thrust of the propeller causes the shaft 25 to move axially and the torsion bars to twist. A wire resistance strain gauge bonded to the torsion bars and connected to electrical circuitry through brush and slip ring contacts 33 may be used to determine the amount of twist or the coaxially spaced movable members may be arranged to constitute opposed plates of a capacitor whose capacitance varies in accordance with the axial positioning of the movable members. The space between the movable members is sealed by providing a cylindrical cover 31 and a flexible disc shaped diaphragm 32.

Title: Improvements in gas lighters
IPC: F23Q2/16
Filed: 1962-06-22
Abstract: 995,452. Gas lighters. FLAMINAIRE MARCEL QUERCIA. June 22, 1962 [June 29, 1961], No. 24052/62. Heading F4F. A gas lighter in which a removable reservoir 1 contains a discharge valve opened by pushing a valve stem 2 into the reservoir comprises a housing 5 in which the reservoir 1 is disposed such that it can be displaced to push the stem 2 against the inner wall of the housing and a resilient annular sealing member 9 disposed around the stem 2 at one end and at the other end around a conduit 7 formed in the lighter body and leading to a burner 8. The housing 5 is formed by two half shells 3, 4, the shell 4 having an aperture 11 covered by a flexible leather diaphragm 10 for displacing the reservoir. A rigid part 12 may be fitted to the diaphragm 10. As the valve stem 2 is depressed, the resilient member 9 which is preferably fixed to the housing 5 is deformed and acts as a return spring for the reservoir. In another embodiment the wall of one half shell is made deformable by either forming in it a circular corrugation, the thickness of the wall being reduced at the corrugation (Fig. 2, not shown), or by providing it with cuts (Fig. 3, not shown) if made of stamped metal sheet. In a further embodiment, Fig. 4 (not shown), a plate is mounted in an opening in the half shell and has peripheral bent tongues which slide in slots in the half shell. In a still further embodiment, Fig. 7, the reservoir 1 is pivoted against a fixed lug 17 on the housing and is displaced by a spring-urged lug 16 on a control member 18A which pivots about an axis 24. A pin 19A on the control member slidably engages an oblique slot 22A in a vertically sliding hood 20A. The latter has a notch 23 to expose the burner 8 when in the operating position. An arcuate slot 25 in the member 18A is concentric about the axis 24 and allows the lug 16 to be pivoted clear of the reservoir 1 to facilitate removal. The control member instead of being pivotally mounted may slide in the body parallel to the axis of the valve stem. In a final embodiment, Fig. 10, the reservoir is displaced by a lug 16A on a control member 18B travelling from the periphery of the reservoir over its convex bulging wall. The control member 18B is pivoted at 27 and carries a hood 20B. A pin 28 on the member 18B parallel to the axis 27 slidably engages an arcuate slot in a fixed plate 36 concentric about the axis 27. A slidably mounted U-shaped box 29 contains a spring which urges the box against the pin 28 and due to the contour of the box, the cover 20B is maintained either in its fully open or closed position. The spring also urges a flint against a friction wheel.

Title: Method for producing metal salts of di-organo-dithiophosphates
IPC: C07F9/165
Filed: 1959-07-14
Abstract: Metal di-organodithiophosphates are obtained by phosphosulphurizing an unsaturated alcohol in a first reaction stage, sulphurizing the product by reaction with elemental sulphur in a second reaction stage and neutralising the product with a metal base, e.g. an oxide of a metal of Group II, III or IV of the Periodic Table, particularly zinc oxide.  The unsaturated alcohols are preferably aliphatic alcohols, especially those containing from 8 to 25 carbon atoms, and more than one unsaturated link may be present.  Cyclic alcohols may also be used.  Specified alcohols are dodecenoyl, palmitoleyl, oleyl, linoleyl and eruceyl alcohols. The phosphosulphurization may be carried out with a phosphorus sulphide, e.g. P2S5, or a mixture of elemental phosphorus and sulphur in appropriate proportions may be used. Suitable phosphosulphurizing temperatures are 85 to 140 DEG C. The sulphurization is generally effected at higher temperatures than the phosphosulphurization, e.g. at 130-250 DEG C. and is preferably effected with less than the stoichiometric proportion of sulphur required to bridge the adjacent unsaturated carbon atoms in the alcohol residues of the phospho-sulphurized product.  The reaction stages are preferably carried out in a solvent for the unsaturated alcohol, e.g. white spirit or spindle oil.  An excess of metal base may be used in the final neutralisation stage.  In an example oleyl alcohol is reacted with phosphorus pentasulphide in the presence of a spindle oil diluent and the product reacted with sulphur at 170 DEG C., filtered and then neutralised with zinc oxide. The products are useful as additives for lubricating oils.ALSO:A lubricating oil composition comprises a lubricating oil containing a metal diorgano dithiophosphate obtained by phospho-sulphurizing an unsaturated alcohol, sulphurizing the product by reaction with elemental sulphur in a second reaction stage and neutralising the product with a metal base (see Group IV(b)).  Suitable metal bases are the metal oxides of Group II, III or IV of the Periodic Table and particularly zinc oxide. Preferred alcohols are C8-C25 aliphatic alcohols but cyclic alcohols may also be used.  Specified alcohols are dodecenoyl, palmitoleyl, oleyl, linoleyl and eruceyl alcohols. Specified lubricating compositions of the defined type are (1) an S.A.E. 80 grade mineral oil containing 5% of a zinc diorganodithiophosphate obtained by reacting oleyl alcohol with P2S5 and then with sulphur followed by neutralisation with zinc oxide and (2) an S.A.E. 30 mineral oil containing the same zinc diorganodithiophosphate and a sulphurized and chlorinated fatty oil product containing 10% S and 6% chlorine.

Abstract: 1321148 Fluid-pressure servomotor systems DORNIER AG 19 April 1971 [26 March 1970] 24236/71 Heading G3P In a multiple channel control system, each servo motor 61 is controlled by an electrically operated jet tube 12 through a relay valve 2 and the supply 95 to each channel is connected through a positioning valve 4 moved in synchronism with the servo motor to a differential pressure valve 3 which connects the supply to exhaust 96 when a fault in the channel occurs. The valves 4 are connected together by a rod 42 and operated by a feed back linkage 93 which also operates the jet tubes 11 while the valves 3 are operated in synchronism with the valves 2 by the fluid from the jet tubes which flows through lines 15, 15' to spaces 14, 14' and 27, 27'. If the signal to one of the jet tubes is interrupted, the failed tube is moved by a feedback connection 94 to a position opposite to that of the operative tube and the relationship between the valves 3 and 4 is changed to connect the source 95 for the failed channel to the exhaust 96. Pressure in a space 53 of a switch-off valve 5 is thus relieved to allow the valve to isolate the source and in a space 40' of a valve 71 to allow this valve to be moved by a spring 73 and provide a by-pass between the two ends of the servomotor. In a second embodiment, the valves 3 are mechanically and the fluid-pressure connections to one of them is reversed and failure of pressure in the defective channel actuates a mechanism which locks the valves in a central position. In both embodiments, a groove 45 in a sliding sleeve 23 connects the fluid supply to the exhaust 96 if the spool 21 of the relay valve sticks.
