Title: Improvements in or relating to fluid circuit control means
IPC: B60T11/10
Filed: 1960-07-08
Abstract: 988,222. Locks. H. J. HARRIS. July 7, 1961 [July 8, 1960], No. 23956/60. Heading E2A. [Also in Divisions F1 and F2] Control means for a fluid-actuated locking device comprises a one-way valve between an operating device and an actuator, the valve being arranged to retain fluid in the actuator; a valve for releasing fluid from the actuator; and a key-operated device for actuating the fluid release valve. As embodied in a system for immobilizing a vehicle having internal shoe brakes, 14 is a ram for expanding the brake shoes filled with fluid from a pedal-or hand-lever-operated master cylinder 22 through the pipe 21; by reason of the non-return valve 23, the ram remains locked "on" unless fluid can escape through the pipe 26, the valve means 11, and the pipe 28, to the reservoir 24. The valve means 11 comprises two spring- biased piston valves 34, 35 in a housing 31. In order to pass from pipe 26 to pipe 28 fluid must traverse the passages 36, 41, 42, 43, 51, 53; as shown the ball valves 37, 44 respectively prevent communication between the passages 36, 41 and 43, 51. In order to release the ram 14 a suitably worded key must be inserted in the barrel 57 of a locking device 55 and rotated to move the plungers 63, 64 a pre-determined amount to the left as shown in the Fig. 1; by means of fluid links through the pipes 65, 66 the piston valves 34, 35 are also moved into such positions that the land 68 on the valve 34 raises the ball 37 and the passages 36, 41 are placed in communication through the annular groove 46, while the land 69 on the valve 35 raises the ball 44 and the passages 43, 51 are placed in communication through the annular groove 49. If the piston valves are moved too far, as by use of the wrong key, the balls drop off the lands 68, 69 into grooves 47, 50. If the valve means 11 is housed within the brake drum, the brakes cannot be released by cutting any exposed pipe. The system may be part of or additional to the vehicle brake system which may be hydraulic, pneumatic or mechanical. As described, a two-worded key is used but the key may have any number of words in connection with a corresponding number of plungers and piston valves. The system may be used to maintain a safe door locked in which case the valve means is used to monitor the action of a dead bolt.

Title: Improvements in and relating to torque-exerting means for gyroscopic instruments
IPC: G01C19/38
Filed: 1944-12-05
Abstract: 621,018. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. Dec. 5, 1944, No. 24297. Convention date, April 10, 1942. [Class 97 (iii)] [Also in Group XXXV] Means for applying a torque between a pivotally mounted part of a gyroscopic instrument and the support in which that part is mounted, comprises an energizable solenoid system of one or more coils displaced from the pivot axis and a permanent magnet plunger system of one or more elongated permanent magnets curved about that axis, one of the systems being mounted on the pivotally mounted part and the other on the support so that the forces generated serve to produce torques which are additive in sense, the sense depending upon the sense of energization of the solenoid system. Fig. 8 shows the application to a gyro vertical 64, pivoting about a horizontal axis 68 in gimbal ring 65, pivoting in turn about a horizontal axis 66 in an outer casing 60. Arcuate magnets 71, 72 are fixed to the gimbal 65 so as to present like poles to the ends of a solenoid 70 fixed to the casing 60. The solenoid 70 is energized in one direction or the other so as to apply erecting torques to the gyro about the axis 66 when a pendulum 80 is displaced relatively to a bail 120, which is caused by a pin 122 on gyro 64 to follow the latter's movement about the axis 68. A second pendulum pivoting on the axis 66 controls the energization of a solenoid fixed to the gyro 64 and co-operating with magnets fixed to the gimbal 65. The electromagnets may be energized by a liquid-level operated switch. Fig. 5 shows a directional gyroscope 31, the outer gimbal ring 34 of which carries a pair of solenoids 52, 53, presenting like poles to the ends of a semicircular magnet 57 fixed by the arm 56 to one of the. trunnions of the inner gimbal ring 34. The energization of the solenoids 52, 53 may be controlled by a magnetic compass so as to precess the gyro into alignment with the compass. Excessive tilting of the gyro causes the plunger 57 to penetrate through the solenoid and the electromagnet then becomes ineffective. Specification 621,014, [Group XXXV], is referred to.

[Also in Division A5] A vehicle of the type described in Specification 1,083,896 (i.e. having a concave depression 26 on one surface) is produced by a method including forming a gelatinous body incorporating the medicament and a volatile solvent, e.g. water, and then drying the body at a temperature such as will not destroy the medicament. According to one embodiment (Figs. 1-5, not shown), capsules (19) are formed in known manner by pitted rollers (12), (13), are washed, and are coated on one hemisphere with an impervious layer 25. On being dried, solvent 17 migrates through pervious wall 22 which collapses to form a depression 26, solid medicament permeating into wall 22. Alternatively, the two hemispheres are dried differentially to obtain the same result; or the body may be moulded directly to the desired shape and then shrunk; or (Figs. 17-19, not shown) two superposed gelatine layers (44), (47) are formed by extrusion, dies (48), (49) stamp out disc-like bodies (50) which are dried, and since each layer contains different medicaments and solvent contents, one shrinks more than the other. Medicaments.-A list is given, including hormones (e.g. insulin, contraceptives), local anaesthetics (e.g. lignocaine hydrochloride), adrenaline, amphetamine, diuretics, analgesics, cardio-vascular reactants, labour-inducing compounds (e.g. oxytocin), antihistamines, diagnostic agents (e.g. radioisotopes), and Vitamin B 12 . Treatment can be discontinued as soon as the desired effect (e.g. labour) has been induced.

Filed: 1938-08-23
Abstract: 514,073. Automatic volume control. HAZELTINE CORPORATION. Aug. 23, 1938, No. 24845. Convention date, Sept. 25, 1937. [Class 40 (v)] Variation of input capacity of a thermionic amplifier when a grid-bias is varied to control gain, is substantially prevented by applying simultaneously variable control potentials to both the control grid and an auxiliary grid of the valve. In Fig. 1, A.V.C. potentials derived from the second detector stage 14 of a superheterodyne receiver are developed across resistances 27, 27<1>, the potential across 27<1> being applied to the control grid 18 of a heptode I.F. amplifier 17 while the voltage across the total resistance 27, 27<1> is applied to the suppressor grid 19. The apparent input capacity of valve 17 decreases with increasing negative potential of grid 18 but increases with increasing negative bias on grid 19, and the ratio of the two voltages is so chosen that the input capacity is substantially constant over a wide range of grid-bias potential. The actual ratio of the control potentials is 2:5 for grid 18 and grid 19 respectively. In a modification the screen grid voltage of a tetrode may be varied simultaneously with and in the same sense as, the control grid-bias to give the same effect. Specification 443,065 is referred to.

Abstract: 259,034. Draper, A. D., Bentley, P. H., and Bentley & Draper, Ltd. Oct. 8,1925. Steering-mechanism. - A steering-damper of ,the friction-disc type for mctor-cycles &c. comprises a shallow cylindrical box h adapted to support one, or more friction discs l and formed with a side opening j for enabling a spanner &c. to be inserted for tightening the expander bolt or nut e at the top of the handle-bar stem. The bottom of the box h is radially slotted, so that it can be slipped over the bolt f beneath the head e, or the bottom may be centrally apertured to engage the bolt when the latter is provided with a removable nut at its upper end. The friction disc l is prevented from turning by a stud n passing through its projecting front part o and through a lug m on the box h, a stub screw p rigid with the top of the box passing through the centre of the disc l and through a second friction disc q, which is adjustably pressed against the disc l by a plate spring or spider u, a washer s, and a hand nut v on the, top of the stub-screw p. A coil spring x may also be, disposed between the disc q and the plate spring u. The friction disc q is prevented from turning by an arm r engaging the channelled upper ends 2b of a two-part clip 2 secured to the upper frame tube b by a bolt 3. The nut v is prevented from being entirely unscrewed from the' screw p by a set-screw y adapted to engage a, shoulder at the bottom of the screw threads on the screw p, or by a stop in the form of a disc on the top of the screw p. The box h is prevented from turning relatively to the steering-stem by binding-screws passing through two lugs z on the bottom of the box, or by radial ribs on the underside of the box engaging notches in the upper edge of the steering- stem. The hand-wheel portion of the nut v may be encased in a removable cap of spongy rubber, which facilitates the operation of the nut and also acts as a cushion in the event of the head of a. racing motor-cyclist being jolted against the handle-bars.
