Title: Hydraulically operated handbrake, particularly for rail vehicles
IPC: B61H15/00
Filed: 1959-06-24
Abstract: 872,098. Locking-rods. SCHWEIZERISCHE INDUSTRIE-GESELLSCHAFT. June 24, 1959 [June 26, 1958], No. 21632/59. Class 80 (3). [Also in Group XXXIV] An hydraulic hand brake system for vehicles comprises a cylinder 10 with a movable piston 11, and piston rod 9 attached thereto, the rod 9 having a ratchet thereon, the brake rigging for the brake blocks 2 and 3 being connected to a fulcrum 6 on one side and to the end of the piston rod 9 on the other side, the ratchet being in contact with a catch 12, the supply of liquid under pressure to the brake cylinder being effected by a hand wheel 38 which through bevel gears 36 and screwed spindle 35 causes downward movement of a piston 34 to pressurize the liquid thereunder which has been supplied from reservoir 33. When the piston 11 has reached the limit of its travel the rod 9 is locked by the catch 12. The brake is released by rotating the hand wheel 38 in the reverse direction so that the piston 34 is raised causing liquid above it to be forced through pipe 39 to the space below piston 16 thus relieving the ratchet catch from its engagement with the teeth in the piston rod 9.

Abstract: 654,125. Collapsable tubes. CALLINAN GILES & CO., Ltd. Aug. 16,1949, No. 21817. [Class 66] [Also in Group XXIII] A collapsable tube containing fluid is closed at one end and open at the other end with means of closure, the tube having near the closed end, at one side, a brush-head, there being capillary openings among the bristles. Preferably the closed end of the tube and the wall of the tube at the back of the brush-head is thickened so as to be non- deformable. In the Figures a hollow tube 10 is closed at one end 11 and open at the other end 12. The main body of the tube 10 is manually deformable and may be moulded from a suitable flexible plastic. The closed end 11 and one side of the wall 13 near the closed end are moulded thicker than the rest of the tube. Into the thickened portion 13 of the side of the tube 10 there are inserted by normal brush-making methods two or more rows of bristles 14, and there are capillary orifices 15. The tube 10 is filled with fluid and the open end is closed by a plug 17 or a cap. Where only a few drops of liquid are required to be added to a specific area the device is held so that liquid flows towards the rounded end 11 from which it is dropped in small quantities.

Abstract: 359,951. Control of D.C. motors. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. July 22, 1930, No. 22067. Convention date, Aug. 10, 1929. [Class 38 (iii).] Varying E.M.F.-Ship propeller motors M1, M2 are supplied from generators G1, G2 driven by prime movers A1, A2. If a propeller shaft is brought to rest by external obstacles the potential difference across a shunt S1 or S2 in the main armature circuit is sufficiently great to actuate a rolling sector regulator R1 or R2 to insert resistance in the field circuit of the corresponding exciter E1 or E2 so that the field and therefore the voltage of the generator is reduced, and the motor current kept substantially at its normal value. The motors M1, M2 may be arranged to work in parallel from one generator by means of switches U1, U2.

Abstract: 633,669. Stiffeners for shirt collars. NEWMAN, M. M. Aug. 9, 1947, No. 22184. Convention, date, May 10, 1946. [Class 141] A stiffener for the front edge of a shirt collar comprises an elongated rigid section which is hollow at least at one end, and flexible means extending from the hollow end or ends supporting a section of discreet rigid members. As shown in Fig. 2, the rigid section 15 is of flattened tubular form and the discrete rigid members are ring-like and clamped to a flexible strip, preferably of stranded fabric, which passes through the sections 15, 16, the ends 17, 18 projecting therefrom. The members 20 have their adjacent edges on the underside cut out so that the section 16 can bend in one direction only, thus enabling the upper end of the collar edge to curve over the tie knot. In a modification, the extensions 17, 18 may be formed as two independent strips. In a further construction, Fig. 5, the flexible strip 25 is secured to a clamping band 27 formed integral with the body 26, which is a thin flat length of material, e.g. steel, and passes through ring-like members 28. The stiffener may be permanently incorporated in the collar seam or may be removable.

Abstract: 1384743 Tare annuling C CURIONI 12 May 1972 [25 June 1971] 22442/72 Heading G1W A manually operated device for tare compensation in the use of a weighing machine, includes a rotatable drum 5 acted upon by a spring 7 connected to the balance mechanism of the machine and in the opposite direction by a return spring 4, the device normally being locked in a zero position by a spring-biased pawl 15 and arm 14. A key 10, corresponding to the tare weight, when depressed, engaged a toothed sector 2 and releases the pawl 15 from arm 14, whereupon the drum 5 then rotates under the action of spring 4 until an abutment 9 on the drum bears against and retains a stop portion 11 of the depressed key, the spring 7 thereby being extended and thus applying a force to the mechanism proportional to the tare weight. An indicator dial 19 fast with drum 5 simultaneously shows the tare weight value through an aperture in housing 1.A crank 18 is provided for resetting the device to zero.

Title: Improvements in or relating to electrical trigger circuits

Filed: 1958-07-14
Abstract: 826,604. Electrical digital - data - storage. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. July 14, 1958, No. 22509/58. Addition to 801,681. Class 106 (1). [Also in Group XL (c)] Fig. 1 shows a bistable circuit in which PNP junction transistors TR1, TR2 are reciprocally coupled between collector and base, and catcher diodes MR10 . . . MR13 limit the emitter voltage swing between earth and - 5 volts. The circuit is triggered in dependence upon the occurrence of a strobe pulse applied at input 16 or 21 and is conditioned by control pulses applied at the terminals 12, 13 or 14, 15 of AND gates comprising rectifiers MR1, MR2, MR3, MR4 respectively. The resetting of the circuit can be produced either by a positivegoing input on lead 17 or by the simultaneous application of positive-going signals on leads 18, 19, 20 of the AND gate shown. Fig. 2 shows the application to a writing circuit for registering information on a magnetic drum the output being taken from the collectors which feed the recording head via transformer T1, and in which rectifiers MR14, MR15 prevent the collector potential from rising above the supply voltage. In the storage system described, each of the two digits of a binary code is represented by two successive magnetized states the order in which these occur being reversed in the two cases. The information to be stored appears at the input in the form of the signal shown in Fig. 3A; this is mixed with the strobe signal 1, waveforms C, Fig. 3, to produce the waveform B which is applied to the input, Fig. 2. When the first digit O begins, transistor TR1 is conducting and transistor TR2 cut off, the emitter voltages of these tubes being as shown in waveforms D and E, Fig. 3, and the current flow in the transformer T1 causes a reverse, i.e. negative saturation of the magnet material passing the recording head. This continues until strobe 2 is applied which causes tube transistor TR1 to conduct restoring the trigger to the state in which it was when the recording of the digit O began. Thus, as shown in waveform G, Fig. 3, a digit is represented by an ordered pair of magnetized states.
