Title: Brake application control devices and to liquid pressure braking systems for vehicles which include such devices
IPC: B60T13/14
Filed: 1972-06-09
Abstract: 1432350 Master cylinders controlled by valves AUTOMOTIVE PRODUCTS Ltd 8 June 1973 [9 June 1972] 27036/72 Heading F2F A floating piston of a master cylinder is moved by operation of a control valve spool in the same bore as the piston which places a first port in the wall of the bore from communication with a second port in the wall to communicate with a third port in the wall, the piston being moved by pressure liquid in a space between the spool and the piston, the space being connected to the first port. In all embodiments, a pedal-operated push rod 43, 43A moves the spool 34, 34A, 51, 51A directly or via a rod 59, Fig. 2, or ring 78, 78A, Figs. 4, 6, via a spring 60, 84, or one or more elastomeric washers 80, Fig. 4. This movement stops communication between the first port 44, 44A, 44B, or 44C leading to brake cylinders 25 and the second port 45, 45A, 45B, or 45C leading to a liquid reservoir, and initiates communication between the brake cylinder port and the third port 46, 46A, 46B, or 46C connected to a liquid pressure source, e.g. a pump controlled accumulator 24 or a rear axle suspension strut, thus providing actuation of the cylinders 25. Furthermore, pressure liuqid communication to the cylinders 25 also provides communication to a right-hand face or differential area face of the piston 13, 13A, 13B or 13C in a chamber 36 between the spool and the piston directly from the port 44, 44A, 44B, or 44C or via a one-way valve 61, Fig. 2, or plate valve 70, Fig. 4. In Fig. 6, further movement of the spool 34A stops communication between the chamber 36 and the outlet port 44C by means of a seal 100 so that further pressurization occurs due to movement of the piston 13C, which is a differential piston. The piston 13, 13A, 13B, on 13C actuates motor cylinders 21 which operates the same brakes as controlled by the cylinders 25, or the cylinders 25 control rear axle brakes and the cylinders 21 front axle brakes when suspension struts are utilized for load dependent braking. If the master cylinder section becomes inoperative, the piston 13-13C abuts the left-hand end of the bore, but the spool valve still operates. However if the valve liquid system fails, then the spool contacts the piston, Figs. 1, 6; or is mechanically coupled via a rod 73, Fig. 5, or the rod 59, Fig. 2, contacts the piston or an extension included or carried thereby, or via two axially aligned rods.

Abstract: 925,516. Photographic cameras. AGFA A.G. Aug. 7, 1959 [Aug. 20, 1958], No. 27164/59. Class 98 (1). In a camera having a continuously movable common setting member for both shutter speed and diaphragm aperture, means are provided for transmitting from said setting member to the diaphragm an adjustment resulting in continuous change of aperture setting at constant shutter speed settings and abrupt change of aperture setting on change of shutter speed setting, so that a substantially continuous change of light value setting is obtained from continuous movement of said setting member. In the form shown, a setting member 13 which is rotatable either by a plunger 2 or by a ring on the camera casing, has two cams 16, 19 which are engaged by a stop 17 of a shutter speed setting device and a stop 26 of an angle lever 22 respectively, said lever being movably connected at one end by a stop 23 and slot 24 to the shutter housing 25 and at the other by slot 36 and pin 35 to a diaphragm control ring 29. The cams are shaped so that over sections 39 of cam 16 the shutter speed does not change but the diaphragm aperture is decreased by sections 20 of cam 19. When the shutter speed is changed over sections 40 of cam 16 the diaphragm aperture is abruptly increased over sections 21 of cam 19 by a corresponding amount. When the pin 17 reaches the end of the stepped section of cam 16 the diaphragm aperture may be controlled directly by a stop 37 on the setting member engaging a stop 38 on the diaphragm control member 29, or, if these stops are not provided, part 46 of the cam surface 19 may be shaped so that the diaphragm aperture is varied by pin 26 moving over this part. Specification 888,973 is referred to.

Abstract: 426,271. Automatic regulation; thermionic valve circuits. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, HOLLAND, W. R., Redlynch, Bilton, and FORSTER, E. W., 101, Grosvenor Road, both in Rugby. Oct. 3, 1933, No. 27182. [Class 38 (iv)] [See also Group XL] In a system for automatically regulating the voltage of a generator, any departure from the predetermined voltage causes a mirror carried by a galvanometer or similar instrument to reflect a beam of light on to a photo-electric cell, 9 or 14, to cause a corresponding variation in the phase of the grid voltage of one or more mercury vapour valves 34, 36 through which the field 37 of the generator or its exciter is supplied. When the generator voltage exceeds the normal value, light shines on cell 9 and the grid potential of valve 10 rises above the negative value to which it is normally set by adjuster 5, causing valve 10 to conduct and energize relay 12 which then opens to insert resistance 21 in the bridge circuit 21, 22, 23, 24 thereby altering the phase of the voltage across the grid transformer 28, 29, 25 fed from the auxiliary A.C. circuit 38. This alteration in phase causes reduction of the current in field 37 with consequent reduction of the generator voltage. Reduction of the generator voltage below normal causes illumination of cell 14 and energization of relay 18 which short circuits 22 and causes such a phase shift of the grid voltage of valves 34, 36 as to increase the current through the field 37. A single photo-electric cell or a " split cathode " cell may be used. The Provisional Specification also describes an arrangement in which the galvanometer and photo-electric cell are replaced by a sensitive relay provided with contacts operating on a bridge circuit in which the A.C. potential may be balanced against a constant potential difference the relay being energized when the bridge is unbalanced.
