Patent GB-200832-A (GB)
IPC: F16G5/18
Filed: 1923-07-13
Abstract: 200,832. Dick, E. July 14, 1922, [Convention date]. Belts and bands.-A V-driving belt particularly adapted for grooved pulleys having axial play or displacement, such as on carriage axles of railway vehicles, comprises thin steel links 9 pivotally connected by extended rivets 10 which secure to the upper and lower faces of the links, bodies 3, 4 of truncated pyramidal form enclosed by an outer leather cover 2. The strip 2 forming the covering is attached by riveting the lower end of the pivot 10 over a washer 7 and is wrapped round the parts 3, 4 the abutting ends being recessed to fit round the upper end of the pivot 10, which is then riveted over a washer 6. The pyramidal elements 3, 4 are preferably formed of metal tubing. The upper surface of the lower element 4 may be convex or curved to facilitate longitudinal bending of the belt, or alternatively the edges thereof may be rounded or a piece of leather interposed. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement in which links 9, Figs. 1 (Cancelled) and 2 (Cancelled), are connected by rivets 10, the pyramidal elements 3, 4 being separately secured by rivets 5 of plate or flat form corresponding to the shape of apertures 8 in the links through which they pass. The two methods of attachment may be employed alternatively in the same belt. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to automatic control apparatus
IPC: G05D23/22
Filed: 1946-06-18
Abstract: 618,458. Automatic control systems for furnaces. JESSOP & SONS, Ltd., W., and LAND, T. June 18, 1946, No. 18226. [Class 38 (iv)] [Also in Group XL (b)] In an automatic temperature control apparatus, in which the illumination incident on a light-sensitive cell corrects deviations from a datum, means are provided for adjusting the damping of a current measuring instrument without substantially effecting the sensitivity, wherein current proportional to the rate of change of the anode current of a gas-filled rectifier valve is applied to the current measuring instrument additional to the current derived from a thermo-couple and a potentiometer connected thereto. As shown, the thyratron 1, which is A.C. energized at the grid and anode through the transformer 13, supplies the furnace heating element 9. The output of 1 is controlled by the variation of the grid swing phase by the light sensitive cell 23, the impedance of which changes with the amount of light incident upon it from the mirror galvanometer 43, energized by the difference voltage from the potentiometer 53 and the thermocouple 47 in the furnace. Damping of the galvonometer during transient changes of the furnace current is reduced, to reduce hunting, by a voltage proportional to the first differential of the anode current, injected into the galvanometer circuit from the transformer 39. In a second embodiment, not shown, condensers are employed in place of the transformer 39.

Filed: 1960-05-24
Abstract: 964,972. Fluid actuation of switches; thermal switches. E. SINGER. May 24, 1961 [May 24, 1960], No. 18349/60. Heading H2B. In a pressure or temperature responsive switch assembly wherein the pressure-responsive element may be a piston, bellows, or, as shown, a diaphragm 30, the pressure-responsive element actuates a switch 87, through a spring-biased bell-crank lever 62. The operating pressure is set by a spring 50 and the pressure differential by adjusting the lost motion between the upstanding arm 64 of lever 62 and the copivotal follower 65 which engages the switch button. The upstanding arm can move between a fixed stop 72 and an adjustable stop 76 carried by the follower 65 (Fig. 5). The follower is biased towards the switch button by a spring 90 whose normal force is greater than the retractive force of the switch but less than the operating force. This spring may be replaced by magnets. A further switch 95 is pivoted to the casing and adjusted with respect to the diaphragm 30 by raising or lowering an arm 100 which is pivotally connected to it at 99. The operating pressure of this switch is determined by a spring 84. In Fig. 9 (not shown) the bell-crank lever is replaced by a straight lever to which is pivotally connected a follower whose movement relative to the lever is limited by stops on the lever.

Abstract: 849,301. Vacuum brakes. GRESHAM & CRAVEN Ltd., and MARSH, G. C. June 5, 1958 [Jan. 12, 1957], No. 18500/57. Class 103 (1). In a vacuum relief valve for braking apparatus atmospheric air is admitted to the vacuum conduit 40 at a branch piece 44 by the lifting of a valve closure member 19 to admit air through the strainers 33. The lifting of valve closure member 19, however, takes place as a result of the flexures of a diaphragm 21, subject on one side in chamber 13, to atmospheric pressure and the effect of spring 29, and on the other side through port 31 and by way of pipe 41 to the pressure in the conduit 40 as at port 43 remote from the branch 44. Such an arrangement gives an improved sensitivity and avoids faulty operation due to the disturbed pressure conditions resulting from the entry of air at a point near to the valve.
