Title: Locks and keys
IPC: E05B35/00
Filed: 1965-03-31
Abstract: 1,093,353. Locks; keys. J. W. TAYLOR. June 24, 1966 [March 31, 1965], No. 13561/65. Heading E2A. In a key-operated lock of the type in which impediments in the lock prevent operation of the lock bolt except by the use of the proper key, 3, 4, 5 entered from either side of the lock, the lock casing 1 contains a barrel 8 mounted for rotation and is formed with a key hole at each end, the key holes and key being so shaped as to control the amount of entry of the key into the lock casing from either side, and the key having a single bit 5 formed with two sets of notches or steps 6 for alternative use according to the direction of entry of the key. As shown, one flange 9 and a wall of a key hole 14 of the barrel 8 is formed with a blind groove 16 for the entry of a projection 17 on the key to limit entry of the key from that side of the lock, entry from the other side being limited by the abutment of the projection 17 with the flange at that side. In other arrangements, Fig. 3 (not shown), the lock casing is formed with a hollow boss (7) at one side to accommodate the inoperative part of the keybit, and in Fig. 10 (not shown), the barrel 8 is provided with a radial arm (18) for operating the lock bolt. In further arrangements Fig. 11-20 (not shown) the key shank is formed with a shoulder and the bore of the barrel 8 is stepped, such that, when entered from one side of the lock, the shoulder abuts the step in the barrel and when entered from the other side of lock, the shoulder abuts the flange at that side.

Title: Improvements in friction clutches
IPC: F16D13/54
Filed: 1936-05-14
Abstract: 450,933. Friction clutches. PLATT BROS. & CO., Ltd., Hartford Works, and DAWSON, H., 27, Brompton Street, both in Oldham. May 14, 1936, No. 13614. [Class 80 (ii)] In a plate clutch comprising plates e splined in a member d and co-operating with plates c, f, g splined on a sleeve a keyed to a shaft b, a thrust ring h adjustably screwed on the sleeve a has a number of radial cam grooves i each engaged by a roller k carried by one end of a link l, the other end of which is free to rock in a socket in the presser ring n, the latter being urged towards the ring h, so as to disengage the clutch, by springs q. A control sleeve o encircling the rings h, n, has an internal cam face p co-operating with the rollers k so that, on moving the sleeve o in the direction of the arrow A, the rollers are forced inwards and the links, acting as struts, force the ring n away from the ring h, thus producing engagement of the clutch. The ring n is caused to rotate with the sleeve a by a spring-loaded detent r engaging one of a number of holes in the plate g. To adjust for wear, the detent is forced out of the hole and the ring n is turned, thus causing the ring h to turn and to screw along the sleeve a, until the detent engages another of the holes. A double clutch is also described.

Title: Apparatus for selecting a sequence of signals from a plurality of recorded data signals
IPC: G06F3/16
Filed: 1956-05-03
Abstract: 837,552. Electric selective signalling. ELDRIDGE, F. R. May 3, 1956 [July 29, 1955], No. 13718/56. Class 40 (1). [Also in Group XXXIX] In a system for selecting one or a sequence of a plurality of recorded data signals, a transmitted information signal is stored and subsequently utilized to select one of the recorded signals to produce intelligence, the final output may be an audible or visual signal and the system may be applied for example to the transmission of weather data, telemetering, or sending landing or flight instructions to aircraft. Eight audio signals are recorded on a magnetic drum 11, Fig. 3, together with four control signals and one of the signals induced in the pick-up heads 23 is connected via a selector switch 119 to earphones 121 in accordance with a binary code from a digital computer 6 transmitted through a radio transmitter 7. The first received pulse after shaping in a pulse trigger unit 15 comprising a flip-flop, renders conductive transistor 136, Fig. 5, in motor start circuit 116 to operate a motor start relay 124 and it and the subsequent pulses in conjunction with shift pulses picked up from a control track by a pickup head 172, Fig. 4, register the transmitted code on three magnetic core stages 150, 152, 154. The registered code is subsequently transferred successively to three buffer magnetic cores 157, 162, 167, and three bi-stable transistor circuits 182, 184, 186 by buffer reset pulses induced by a further control track in pick-up 178. The code on the output circuits A-L of the bi-stable transistors biases the rectifiers in the tree gate 119 to connect the selected pick-up head 226, 239-235, 248 to the headphones 121 through a two-stage transistor amplifier 250 251. The motor is shut down by a stop-pulse induced in head 143 rendering transistor 137 conductive at the end of the cycle. The bistable circuits and the magnetic cores are reset at the end of the cycle and between the stages by control pulses in the manner described with reference to Fig. 6 (not shown), the start pulse magnetizing storage ring 150 in a counterclockwise direction. In a modified arrangement described with reference to Figs. 1 and 2 (not shown), decimal pulse chains are transmitted and converted to binary in a gas discharge tube counter to operate single-pole, double-throw relays in the selector switch. The use of additional digits to allow for selection from a greater number of recorded signals is mentioned and storing the data signals by sound tracks on a photographic plate is suggested as an alternative. Production of the final signal on a phosphorescent screen is also referred to.

Abstract: 1459601 Monitoring battery voltage WESTINGHOUSE ELECTRIC CORP 29 March 1974 [30 March 1973 14 June 1973] 13931/74 Heading G1U [Also in Divisions G4 and H3]  In a battery monitoring circuit for use for example in a battery powered vehicle and designed primarily to prevent excessive damage to the battery, if, having started with a good battery having a voltage above a 1st threshold level, 11, Fig. 1, the battery voltage falls below a 3rd threshold level 13 then a first warning indication 14 is given, if the battery voltage does not thereafter rise above a 4th threshold level 20 before the expiry of a first time period then the first warning indication is replaced by a second warning indication 23, and finally if the battery voltage does not thereafter rise above a 5th threshold level before the expiry of a second time period then a particular operative feature of the vehicle is disabled 31. If, after the operative feature has been disabled, and providing the battery voltage has at no time fallen below a 2nd threshold level (substantially zero), then once the battery voltage rises above the 5th threshold level the second warning is discontinued and the disabled feature is reconnected. If at any time the battery voltage falls below the 2nd threshold level, then the vehicle is immediately disabled until the 1st threshold level is exceeded - which means in practice until a new battery is installed. A circuit Fig. 3 (not shown) employing conventional threshold circuit and transistor switching techniques is described.

Title: Improvements in or relating to the purification of industrial effluents
Inventor: BADGER EDWARD HENRY MICHAEL
IPC: C02F3/12
Filed: 1957-05-03
Abstract: Industrial effluents containing mono- or polyhydris phenols, thiosulphates or thiocyanates, e.g. gas-works effluents such as those from ammonia stills, are aerated in the presence of aerobic micro-organisms capable of oxidizing the specified substances, the process being effected without the addition of sewage or the return of settled sludge to the effluent.  The process may be effected in a tower filled with packing inoculated with the micro-organism, the effluent being circulated through the tower and an associated sump and air being passed in counterflow to the effluent.  Alternatively, the process may be effected in a tank either by vortex aeration or by passage of air into the tank, and in the latter case the air leaving the tank may be passed to a tower in which foam is destroyed by an anti-foaming agent.  In any p  event the process may be effected in a number of stages, treatment with a micro-organism suitable for the oxidation of one of the specified substances being followed by treatment with another micro-organism suitable for the oxidation of another of the substances, and between the stages the effluent may be given a non-biological treatment, e.g. sterilization or flocculation, particularly in cases where the reaction products in one stage would adversely affect the micro-organisms used in a later stage. The micro-organisms may comprise bacteria, yeasts or filamentous organisms and nutrient materials therefore, e.g. phosphates, are added to the effluents, if necessary.
