Title: Improvements in or relating to locks
IPC: E05B67/22
Filed: 1937-02-26
Abstract: 476,357. Padlocks. CASTELL, J. H. Feb. 26, 1937, No. 5760. [Class 44] In a padlock of the type in which at least one limb of the shackle is locked in the casing by means of at least two locking bolts, which move transversely with respect to the shackle, means other than keys are provided for restraining the locking bolts when the shackle is unlocked from returning to the position of re-engagement so that they trap the key in the lock casing. The shackle 12 is locked in the casing by means of the spring-loaded locking bolts 19 engaging the grooves 18 in the limb 13. The bolts 19 are withdrawn by key 26 engaging the notch 19b. When released the shackle 12 is ejected by spring 17 thus causing the abutments 18a to come opposite locking bars 19 and lock them in the withdrawn position. The shape of the notch 19b prevents the rotation of the key in the opposite direction so that it cannot be released until the shackle is locked again by the bolts 19. A horizontal plate 32 attached to cover 24 coacts with a flat 33 on limb 13 to limit ejection of shackle 12, and with the groove 34 to prevent rotation of the shackle until it is fully ejected. A flat 25b on the key barrel 25 co-operates with a block 29 to limit the movement of the barrel 25 to prevent strains on the bolts 19 when the key is trapped. A pin 31 in the path of the key fingers 26a and attached to the block 30 is variable in length and position on the block so that the number of variations available from standard parts may be increased. The pin may be replaced by a block attached to the cover with a slot in it to allow the passage of a key finger. The number and position of the bolts 19 may be varied at will.

Title: Brake pressure control means
IPC: B60T17/22
Filed: 1973-01-31
Abstract: 1366807 Combined pressure warning device and reducing valve; valves GIRLING Ltd 31 Jan 1973 [8 Feb 1972] 5777/72 Headings F2E F2F and F2V A pressure differential warning device has first and second pressure spaces 8, 9 separated by a pressure responsive member 4, each space having its own inlet and outlet, the first space having its outlet 8B connected to a reducing valve and a by-pass outlet 8C closed by a valve member with an annular seal normally closed by face-to-face engagement with a valve seat and which opens upon movement of the responsive member upon the pressure being less in the second space than the first space. An electrical switch 7 has a plunger 6 which is actuated by movement of the responsive member 4 due to a V-groove. Upon movement of the member 4, say to the right, a lefthand sealed sleeve 5 is held stationary by contact with the switch, but a righthand sleeve 5 is moved by a circlip on the member 4. Upon subsequent balancing of pressures in the spaces 8, 9, the member and righthand sleeve 5 are actuated by fluid pressure to move the member back to its central position. A valve head 22 of the reducing valve is moved from its seating 23 by pressure fluid from the space 8 until the force on the lefthand face equals that in the righthand annular face causing subsequent closing. Thus the flow is metered through this valve to produce a lower downstream pressure. The fluid from the space 8 actuates rear wheel brakes, and that of the space 9 actuates front wheel brakes, the pressure of the rear brakes being lower. Upon failure of the front brakes due to pressure loss, the by-pass valve 10 allows full pressure for rear brake actuation.

Abstract: 507,684. Coiling slivers. ASHTON BROS. & CO., Ltd., and BAYES, A. W. Feb. 24, 1938, No. 5811. [Class 120 (iii)] The sliver-coiling mechanism of a carding- engine or other textile machine is converted for use with a can or container C of diameter larger than the usual A, Fig. 3, by altering the relative dispositions of the axis of the container and of the locus or path of rotation D of the hole in the upper revolving coiler plate whereby a larger diameter container can be accommodated without being obstructed by the adjacent framework of the coiler mechanism or of the machine while permitting the sliver to be coiled down in the container so that its coils touch the wall of the container. The usual central hole, E or F, is-left in the coiled sliver and the diameter of the container C should be at least two inches greater than, that of the container A. : Where possible the axis of the container and of the lower revolving plate may be moved along the vertical plane BEF by an amount equal to the increase in radius of the container, B representing the axis of the vertical driving shaft. Alternatively the upper coiler plate and the lower supporting plate are moved relatively and through an angle YBE, Fig. 4, to produce the coils D<1> or the movements of Figs. 3 and 4 may be combined as shown in Fig. 5. In applying this last method to the coiler of a revolving flat carding-engine the base a, Fig. 7, is cut away centrally at a<1> and the bearing plate b and support plate c moved so that the axis moves from X to X<1>, a false bottom d being inserted and an auxiliary plate c<x> mounted on the plate c.

Title: Fault recorder for trigger mechanism of motor vehicle safety device
IPC: B60R21/01
Filed: 1973-02-06
Abstract: 1387375 Automatic fault indication NISSAN MOTOR CO Ltd 6 Feb 1973 [9 Feb 1972] 5868/73 Heading H2K A fault recorder for a vehicle safety device, e.g. of the gas-bag type, comprises means 11 responsive to a defect of a trigger mechanism 10 of the device to produce a signal, a first recording means 13 for recording the lapse of time from the start of the signal until the operation of means 15 responsive to actuation of the safety device and second recording means 20 for recording the lapse of time from the start of the signal until the operation of means 22 responsive to a collision of the vehicle. As shown, the trigger mechanism comprises electric detonators RS1, RS2, diodes D1, D2 collision sensors A, B and resistors R1, R2. Comparators C1 ... C3, an inverter I 1  and an NAND gate NA 1  provide an output to the base of a transistor Q1 in the event of a fault condition. The transistor Q1 conducts to blow a fuze F so rendering a transistor Q2 conducting to light a warming lamp P, and to cause an inverter I 2  to render a transistor Q3 conductive so that current flows through both recording means 13, 20 which may be electrolytic devices. If now the safety device is operated by the actuation of one of the detonators, signals to a NOR gate NOR 1  from a camparator C4 and the inverter I 1  are such that this gate provides an output to render a transistor Q4 non-conductive to stop the recording means 13. If a collision occurs, a switch 22 interrupts the circuit for the recording means 20. The recorder may determine whether the undesired operation of the safety device causing an accident, or lack of operation in the event of a collision is due to a fault condition which has not been attended to.

Abstract: 805,046. Injector devices for mixing liquids. WADDINGTON, R. S., and DUVAL, B. Feb. 22, 1957 [Feb. 27, 1956], No. 6084/56. Class 71. An injector device for mixing liquids comprises a body part 1, Fig. 1, formed with a venturi passageway having a convergent inlet 2, an elongated throat section 3 and a divergent outlet section 4, the latter having an angle of divergence of from 2¢ to 7¢ degrees, through which flows the primary liquid, the secondary liquid being induced through a passageway and port 7 communicating with the throat section 3. The Specification also describes addition dimensional characteristics of the venturi passage. The port 7 leads from a valve chamber 8 provided with a slide valve 11 (omitted from Fig. 1 but shown in Fig. 4) which controls the passage 32 of the secondary liquid and is provided with a part 12 which fits into the port 7 so that on closing the valve the entry of secondary liquid into the primary streams ceases immediately. The setting of the valve 11 is controlled by a rotatably adjustable cam 17 provided with locking means. The flow of secondary liquid to the valve chamber 8 is controlled by a second valve opened by the flow of primary liquid. A lift valve 51 has a stem 49 joined to a diaphragm 53 clamped between two parts 48, 54. When the primary liquid is supplied to the venturi passageway some of the liquid flows through conduit 59 and 57 to the underside of the diaphragm 53 thus causing the valve 51 to lift and allow the flow of secondary liquid from an inlet 43 to pass the valve 51 and stem 49 to the chamber above the diaphragm from where it flows to the valve chamber 8 through passage 32, Fig. 4. The end 5 of the body part 1 may be constructed in various ways for attaching to a water tap and the supply of secondary liquid may be from a tank the arrangement being such that atmospheric pressure is obtained in the tank at a fixed level from the bottom. In a modified form an additional port 7 may be provided with similar valve means for the secondary liquid or a third liquid or the throat section may contain a circular groove for the secondary liquid. A non-return valve may be provided in the primary passage to prevent back flow of the mixture if a blockage occurs in the outlet.
