Title: Improvements in or relating to closure caps for liquid receptacles
Inventor: TUFNELL DERRICK PERCIVAL
IPC: B60K15/04
Filed: 1957-11-23
Abstract: 901,978. Valves. GENERAL MOTORS Ltd. Nov. 24, 1958 [Nov. 23, 1957], No. 36571/57. Class 135. [Also in Group XVII] A fuel-tank cap, of the kind having a sealing member 9, within the cap, to engage, through a gasket, with an annular seat on the filling neck of the tank, is provided with two valves each of which responds to a different pressure-condition within the tank. In Fig. 1, the cap has a coverportion 1 with inturned tabs 2 which co-operate with a bayonet seating on the filler neck, the connection being spring-loaded by the spring- disc 5. Within the sealing member 9 are three inverted cup-members 7, 16, 18, the member 7 being secured to the cover 1 and to the sealing member 9 which includes an annular ridge 11 on which rests a gasket 20. The gasket is sandwiched between annular flanges 17, 19 on the cup-members 16, 18, which are a press-fit one within the other. The gasket is pressed against the seat-ridge 11 by a spring 15 to form a first valve which is openable by an excess vapour-pressure within the tank. The central part 22 of the inner cup-member 18 is upset to leave an annular portion in which are apertures 23. A central aperture 24 in the outer cup-member is aligned with the part 22 and with an aperture 12 in the base of the sealing member 10. Surges of fuel within the tank may cause fuel to impinge on a loose washer 21 resting on the part 22, thereby displacing it upwardly to close the aperture 24; this constitutes the second valve-member. Normal venting of the tank is effected by the apertures 12, 23, 24 and 8 and by a hole 6 in the disc 5. In Fig. 2, the two valves are formed by depressions 41, 42 in a sealing member 36 co-operating with apertured cup-members 43, 50, the anti-surge valve comprising a loose washer 52 and the vapourpressure-responsive valve being a spring-pressed washer 46.

Title: Improvements relating to weighing devices for suspended loads
Inventor: BACHE JOHN KENNETH
IPC: G01G19/14
Filed: 1958-11-14
Abstract: 868,701. Weighing apparatus. SALTER & CO. Ltd., GEORGE. Nov. 2, 1959 [Nov. 14, 1958], No. 36631/58. Class 143 The weight of a load in suspension (e.g. from a crane) is measured by a device in which the load is supported by a vertically movable member coupled to resilient load-balancing means through at least one load-reducing arrangement whereby the weight of the load may be balanced by a relatively small force exerted by the resilient means. The load-reducing arrangement includes a lever to which are attached, at points separated by a distance which is small compared with the length of the lever, an elongated member by which the lever is suspended from the frame of the device and an elongated member acted on by the load. As shown in Figs. 1 and 2 the vertically movable load supporting member 5 is threaded to receive the shank 7 of a hook carrying the load and is guided for vertical movement by leaf springs 36. Movement of the member 5 is transmitted to the lever 16 of a first load-reducing arrangement by a pair of bars 12, the lever being suspended from the framework 1 by like bars 20 horizontally offset from the bars 12. The effect of the load is thus to cause the lever 16 to rotate, the bars 12, 20 flexing to permit this. The flexure produces a deflection-resisting couple which increases with deflection but this effect is counteracted by an increase in the horizontal separation of the effective points of connection. to the lever of the bars 12 and'20 respectively.' The lever 16 is coupled to the load-balancing spring 31 through a second load-reducing arrangement comprising the lever 28 and blade springs 25, 29 respectively corresponding to the bars 12, 20 of the first load-reducing arrangement. Indicating means. The end 30 of lever 28 to which the spring 31 is attached is forked (see Fig. 4) and bridged by a plate 48 having a pin 47 engageable in a V-slot 46 in the rack 42 of rack- and-pinion indicating means. A spring 49 holds plate 48 and rack 42 in engagement with the pin 47 in the apex of slot 46. If the apparatus is shock-loaded, the spring 49 is overcome and the pin 47 rides along one limb of the slot thereby protecting the rack and pinion from damage.

Title: Improvements in or relating to coupling arrangements in anti-skid governors
IPC: B60T8/74
Filed: 1956-12-05
Abstract: 807,177. Fluid-pressure brakes. KNORRBREMSE G.m.b.H. Dec. 5, 1956 [Dec. 9, 1955], No. 37183/56. Class 103 (1). In an anti-skid device for use on railway vehicles, a shaft 1 is connected by way of an elastic coupling 3 to an axle of a vehicle wheel 5 a flywheel mass 7 is freely mounted on the shaft 1 and is non-positively connected thereto by means of an axially-displaceable control member 9 which acts as a driving member and which is so mounted in a slot 11 in the shaft 1 that the rotations of the shaft are imparted to the control member, and the latter member is displaceable in an axial direction of the shaft. Rollers 13, provided on control member 9, are pressed by the action of spring 15 against the cam track 17, shaped as shown in Fig. 2, which act as control cams and are formed in recesses 19 of the flywheel mass 7 which is pivotable concentrically with the shaft 1. Concentrically to the axis of rotation of the shaft 1, the control member comprises a push-rod 21 which with the interposition of a clearance 23, is adapted to co-operate with coaxially arranged spring- loaded governor valve 25. The latter is made to bear against its seat in the governor valve housing 29 when in the position of rest by means of compression spring 27 and is acted upon by the pressure in the brake cylinder 31, by way of the control pipe 33 and branch pipes 35. By way of the said control valve 33 the governor valve 25 communicates with the control valve 37, the brake air reservoir 39 and the train pipe 41. During the braking operation, as soon as skidding on the rails causes the vehicle wheel 5 to be braked and retarded more strongly than corresponds to a predetermined limit value of ratardation permissible for the braking operation, owing to the inertia of the flywheel mass 7 the latter rotates relatively to the shaft 1 and therefore relatively to the rotary movement of the control member 9 and rollers 13 are urged out of their position of rest in the depressions 43 so that non-positive connection between control member and flywheel mass is interrupted, the rollers 13 travelling outwards along the control cam surface 17 as far as the abutment surfaces 45 or 47, depending upon the direction of rotation of shaft 1, to move the push-rod 21 and open the governor valve 25 in opposition to the brake cylinder pressure prevailiing in the valve chamber and in opposition to the force of the spring 27. The governor valve thus opened vents the governor valve chamber and, by way of pipes 33, 35, the brake cylinder 31, so that the locking brake shoe is released, which allows the vehicle wheel to accelerate again and the rollers 13 are released from the abutment surfaces 45 or 47 and move back into the depressions 43, whilst at the same time the governor valve closes and the vehicle wheel is again braked. If the brake block again locks, the control operation which prevents the wheel from skidding is repeated until the locking tendency of the brake is eliminated.
