Filed: 1939-08-23
Abstract: 533,721. Latches ; locks. BULLEN, A. G., and KRESTA FOUNDRY & ENGINEERING CO., Ltd. Aug. 23, 1939, No. 24219. [Class 44] A swinging latch comprises a cranked lever pivoted at 7 in a casing 1 the longer arm 6 having a latch nose 6a projecting from the casing to engage a suitable keeper, under the action of a spring plunger 13 mounted in a barrel 16 pivoted at 15 so as to be angularly movable. The angular position of the barrel is determined by a slider 17 having an upstanding web gapped at 17b to embrace the barrel. The slider is operable by a key, not shown, inserted in keyhole 22 and co-operating with a V-form notch 17a in the slider. In the raised position shown, the plunger bears resiliently against the arm. When depressed by clockwise operation of the key the plunger is forced into the barrel, the end of which bears against the arm to prevent positively release of the latch. With the plunger in the shown position the latch may be released by a spindle-operated follower, not shown, acting on the shorter lever arm 6b, or, as shown, by a slider 8 bearing against the arm 6b. Slider 8 is raised to effect release by a press-button operated member having an enlargement 9 acting on an incline 8a on the lower end of the slider 8. This operating member may pass completely through the door &c. so that it may be pushed from one side or pulled from the other, its movement agreeing with the opening movement of the door &c. As shown, however, it is operated by a press-button 5 projecting through a bowed handle, not shown, the handle being attached to the door, together with the latch casing, as described in Specification 533,722 which is referred to. As shown the enlargement 9 is formed on a sleeve 12 slidable on a fixed pin 11 and in a tubular casing 10 projecting from the latch casing cover-plate 1a, being urged to the right, Fig. 3, by an enclosed spring. A reduced spindle portion projects from casing 10 and receives the button 5 which has a flange bearing against the inner face of the bowed handle to limit its outward movement. Adjustment for different thicknesses of door may be made by using a button of appropriate size. Alternatively, release may be effected by arranging the key to engage and operate slider 8 directly. or indirectly through a second slider mounted on slider 8, or by arranging the key to operate slider 17 beyond the normal position, causing the plunger 13 to side beyond pivot 7 and act on the shorter lever arm. The keyhole may be provided with fixed guard members requiring a correspondingly cut key.

Title: An electrical system for controlling electric motors for effecting the latching of coke oven doors
IPC: C10B25/12
Filed: 1951-10-22
Abstract: 694,621. Control of several A.C. motors. KOPPERS GES., H. Oct. 22, 1951 [Oct. 23, 1950], No. 24611/51. Class 38 (iii) [Also in Group XII] Relates to a system for controlling electric motors 31, 32, which effect the latching of coke oven doors (see Group XII) where the closure-pressure on the door is produced by a spring between the latch and door body, whilst the spring is slightly compressed by a nut carried on a motor-driven screw for the purpose of opening the door and relieving the latch of the spring-pressure, Fig. 1 (not shown). A relay 35 is adapted to be closed by a coil 49 the current through which can be interrupted by a timing relay 48 so stopping the motor after the door has been closed. When the motor is reversed for opening the door a resistor 64 is included in circuit, this resistor being so calibrated that the motor is stalled when the spring has been compressed sufficiently to allow unlocking of the latch. Spring-actuated doors of the type referred to may be used in a battery which also includes doors of the kind in which the sealing- pressure is applied directly through a latch screw, Fig. 2 (not shown) the gear for operating the doors being moved along the battery. During the travel of the door-operating assembly along the battery from one kind of door to the other the control system is automatically changed to suit the type of latching required. In order to close a door of the secondmentioned type a switch 57 is closed by a cam 65 and contacts 44 are manually closed. The relay 35 is thus energised and the motor runs until it is stalled at the instant determined by appropriate selection of resistor 34, whereupon the switch 43 may be returned to the neutral position. To open the door, contacts 54 are engaged to close relay 42, the resistors 64 being short-circuited. The switch 57 is opened during the operation of doors of the kind shown in Fig. 1. The motors 31, 32, may respectively operate lower and upper latching devices of each door, a switch 36 selecting the motor which is to be operative.

Filed: 1968-05-23
Abstract: 1,186,338. Adapters for automatic disc record-players. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 23 May, 1968 [2 June, 1967], No. 24752/68. Heading G5R. An adapter for use with a record-player spindle of the kind having a shoulder and a trigger arm comprises a body having an offset portion forming a shoulder, a bore, and a horizontally-displaceable actuating member in the body, the inner end of the actuating member having a vertical portion and, above and below the vertical portion, inclined portions to facilitate application and removal of the adapter; the lowermost of the portions referred to is received on the shoulder of the spindle when the adapter is in use. When the adapter 5, Figs. 1 and 3, is slid on to the spindle 2 of the automatic changer, the upper end of the spindle 2 encounters an inclined portion 8d, Figs. 3 and 4, of the actuating member 8 and thereby pushes the member 8 sideways, the force of spring 9 being overcome. When the adapter has come to rest on top of spindle 2, the member 8 resumes its normal position as shown in full lines in Fig. 4. When the adapter is withdrawn again, the part of spindle 2 above its shoulder 2a encounters another inclined portion 8c of the actuating member 8, thereby pushing it sideways temporarily. In use, records are stacked on a shoulder 12 and retained by a record holder (not shown) located on top of the stack. The lowermost record is released, when appropriate, by conventional actuation, to the right of a trigger arm 3, Fig. 4, located in the spindle 2. The trigger arm pushes actuating member 8 to the right against the force of spring 9 so that the flat tongue 8a pushes the lowermost record off the shoulder 12. The right-hand position of parts 3, 8 and 9 is shown in broken lines in Fig. 4. Preferably a groove 7 is provided at one side of the bore 6 in the adapter 5; this groove accommodates the trigger arm 3 and record keeper 4 of the spindle 2, Fig. 1, and serves to locate the adapter angularly on the spindle.

Filed: 1920-08-26
Abstract: 150,355. Salles, P. M. R. Aug. 27, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Generating by electricity.-Liquids heated by the passage of current therethrough are driven from the heating chamber when vapour is produced so as to diminish the effective area of the electrodes and thus maintain the liquid at its boiling-point without excessive evaporation; they may similarly 'be maintained at a temperature below the boiling-point by the expansion of air in the heating chamber. A temperature above the normal boiling-point may be maintained by suitable pressure arrangements. In a radiator, Fig. 1, the electrodes C and a metal sheath B are supported in a chamber A by an insulating-plug D having a needle-valve E, the operating handle F of which is of insulating material and carries the supply-wires, connexion being made with the electrodes when the valve is closed. Alternating current is used and the gases formed are occluded by the electrodes and recombine. Circulation between the heating chamber A and the outer limb is controlled bv a valve I. The radiator is filled through a tube at the top of the chamber A. A heater, Fig. 3, for immersion in a liquid comprises an outer closed tube J forming one electrade, closed by an insulating stopper O carrying the inner electrode K. The inner electrode has a reduced part L to which is soldered a ring N carrying a washer M. The tube J is first filled with water and the tube K is half immersed; the whole is then inverted and the tube K pushed right in. Water remains only in the space between the tube L and the tube J, the water within the inner tube leaving by an aperture R in the stopper. In a flow heater the water-supply is connected to a vessel surrounding the heating-chamber and water is drawn in variable proportion from the outer and inner chambers by a two-way valve. There may be three electrodes connected to the phases of a three-phase system, the enclosure being connected to the neutral wire. The invention is applicable to portable vulcanizers, sterilizers, steamgenerators for weaving or for vapour baths, and autoclaves.

Abstract: 412,799. Thermostats. BRESSON ET CIE, 241, Avenue Gambetta, and THOMAS, S. J. B., 108, Boulevard Jourdain, both in Paris. Sept. 7, 1933, No. 24814. Convention date, Nov. 30, 1932. [Class 64 (ii).] A compensated thermal switch has the current carrying thermal member in the form of a Y-shaped strip cut from a bimetallic blank and arranged so that the current passes only through the two converging limbs of the Y-shaped strip. As shown in Figs. 1 and 2, the Y-shaped strip a, a<2> has two converging limbs a which are bent over near their ends and clamped at a<4> to two terminals. The current thus passes directly through the limbs a and the heat produced is conducted to the third limb a<2> which carries a contact a<3> at its free end. Opposite the contact a<3> is mounted a contact b<1> mounted at the end of a second relatively fixed bimetallic strip b which has its end clamped in a block c and has an adjusting screw d. The longitudinal axis of the strip b is arranged to be in a different vertical plane from that of the movable strip a, a<2> to prevent the heating up of the latter from affecting the former strip, any bending of this strip arising from, and compensating for, changes in ambient temperature.
