Title: Improvements in or relating to hydraulic master cylinders
IPC: B60T11/224
Filed: 1945-02-08
Abstract: 597,692. Hydraulic brakes. RADFORD, L. Feb. 8, 1945, Nos. 3195 and 5906. [Class 103 (i)] In a hydraulic master cylinder of the kind comprising high and low pressure pistons, the pistons are moved simultaneously, in an operation of the cylinder, until the hydraulic pressure is sufficient to cause compression of a spring through which the low pressure piston is operated, the high pressure piston then proceeding alone. According to Fig. 1, the rod 7 of the high pressure piston 6 may be connected to a brake pedal and is slidable in a sleeve 4 which carries the low pressure piston 3, the sleeve being slidable in an extension 5 of the low-pressure cylinder 1. A spring 8 which abuts on a nut 9 on the rod 7 normally holds the sleeve in the position shown relatively to the rod, in which projections 15 on the sleeve engage the ends of slots 16 formed in the rod. A flange 13 on the end of the sleeve normally holds a spring- urged ball valve 12 off its seat in a transverse bore 11 in the rod 7 so that the cylinders 1, 2 communicate through this bore and a passage 10. In operation, the pistons 3, 6 thus move together to displace liquid through the port 17 to the brake cylinders until the pressure becomes sufficient to cause the spring 8 to be compressed. The consequent movement of the rod 7 relatively to the sleeve then permits the ball-valve 12 to seat, cutting off the cylinder 1 from the cylinder 2 and rendering the piston 3 inoperative. In a modification, Fig. 3, the communication between the cylinders is provided by longitudinal passages 19, 21 in the rod 7 and its piston and a transverse passage 20. Spring- loaded ball-valves 22 in the passages 21 are normally held unseated by the engagement therewith of an extension 25 of the sleeve 4. A brake operating cylinder 26 supplied from cylinder 2 by passage 17 and the piston of which is connected to an operating lever 29 may be attached to or be formed integral with the cylinder 2. Reference has been directed by the Comptroller to Specifications 407,677, 538,785 and U.S.A. Specification 2,009,105.

Filed: 1945-02-08
Abstract: 593,704. Lifting-jacks. CARLEY, R. Feb. 8, 1945, No. 3202. [Class 78(iii)] [Also in Group XXXII] In hydraulic tipping gear for a motor vehicle, the oil for pump-feed purposes is contained in a jacket surrounding the ram cylinder, and one end closure of the cylinder and jacket includes hollow trunnions connected to the pump and enclosing a control valve operable to cause fluid to pass into the cylinder or out of the jacket. As shown, the oil is forced past the non-return valve 33 through the trunnion 19 and a port 29 into the cylinder 5, a valve 31 venting excessive pressure into the jacket 7 surrounding the cylinder 5. A pipe 8 connects the jacket with the pump suction, the flow being by gravity. A lightly loaded relief valve 36 operates to prevent the ram 6 from. passing beyond the desired outward position, the cylinder pressure being vented to the jacket at this position. The return of the ram 6 is permitted by lifting the ball valve 21 from its seat by the screwed rod 24, the fluid being passed through the port 28 to the jacket 7 and from thence to the pump inlet.

Title: Improvements in or relating to automatic record changing gramophones
Inventor: CADDY EDWARD WILLIAM JOHN
IPC: G11B17/16
Filed: 1957-01-31
Abstract: 823,811. Automatic gramophones. GARRARD ENGINEERING & MANUFACTURING CO. Ltd. Jan. 29, 1958 [Jan. 31, 1957], No. 3388/57. Class 40 (2). A centre-post type gramophone recordchanging mechanism has a swinging gauging member 28 carrying an upright element 28a, which is caused automatically to engage the maximum diameter of the records awaiting play so that one of the steps 30-34 of the attached member 29 is made available for engagement by the element 5 of the member 4 which is connectable to the pick-up arm 1; the pick-up arm is automatically lifted and then caused to swing inwardly to an appropriate point so as to engage the starting groove of the record to be played. While this arrangement will only allow the playing of records of non-increasing order of diameter, a further arrangement allows for the intermixing of e.g. 10-inch and 12-inch diameter records in any order. The step 31, corresponding to 10-inch records has a working face of double the azimuthal length of the remaining steps 32-34 so that whether the element 28a senses a 10-inch or 12-inch record, some part of the step 31 is placed in the path of the element 5. A ramp 40 is attached to the arm 28 below the level of the stacked records at such an angle that the edge of a 12-inch record, during descent to the turntable, moves the arm 28 outwardly and allows the element 5 to engage the " 12-inch " step 30, whereas a 10-inch record, whose outline is indicated by the reference 36, will not affect the ramp 40 significantly. To allow for this outward movement, the arm 28 is urged inwardly by a link incorporating a light tension spring operated by a further cam and lever arrangement driven from the turntable (Fig. 1, not shown). In the absence of a record to be fed to the turntable, the arm 28 swings inwardly sufficient to operate a stop mechanism and means to prevent the lifting of the pick-up. Details of the arrangement and the operation of the mechanism are also described in the Specification.

One or other of the levers 2a, 2b is adapted to be held by arresting hooks 11a, 11b under control of a pattern mechanism, such as a card 4, reading needles 5, draw needles 6 and draw rails 7, so that the other end of the baulk is moved forward by its associated pusher rail to operate the jack and heald frame. If neither of the levers 2a, 2b is held the baulk oscillates freely with the pusher rails without moving the jack. If both levers 2a, 2b are held the baulk is held in its forward position. The arresting hooks 11a, 11b may be actuated by electromagnets 40, 41, Fig. 5 (not shown), under control of switches 46, 47 operated by reading needles and a 3-position switch 48 operated by a cam 50 to switch over from one electromagnet to the other. In a modified arrangement, Fig. 3 (not shown), the abutment surfaces 30a, 30b for the pusher rails are formed on the baulk lever 1 itself and the ends of the lever are shaped as at 29a, 29b to co-operate with the arresting hooks. In another arrangement, Fig. 4 (not shown), the baulk lever is formed by two spaced plates connected by pins 33a, 33b which pins co-operate with the arresting hooks.
