Title: Improvements in and relating to Wireless Signalling Systems.
IPC: H03C1/10
Filed: 1918-02-01
Abstract: 130,369. British Thomson - Houston Co., (General Electric Co.). Feb. 1, 1918. Wireless signalling. -A wireless transmitting-apparatus employing modulated continuous waves has the aerial tuned to a frequency equal to the sum or difference of the wave frequency and the modulating or amplitude-pulsation frequency, and the circuit of the source of oscillations, preferably a highfrequency alternator, is tuned to the wave frequency or frequency of the source, with the object of keeping the current supplied by the source in phase with the electromotive force. When several modulating frequencies are employed, the aerial is tuned to the wave frequency plus the highest modulating frequency. If the amplitude pulsations are produced by speech currents, the aerial is tuned to the wave frequency plus the mean speech frequency, say 800 to 1000. In the apparatus shown in Fig. 1, the aerial 1 is supplied from a high-frequency alternator 2 which is connected across an inductance 32. In shunt to the aerial is a magnetic controller 5 arranged as described in Specification 128,682 and connected to one or more alternators 17. 18, 19 and signalling- keys 26, 27, 28. The circuit of the high-frequency alternator 2 is tuned to its own frequency by a condenser 31, and the value of the inductance 32 is so chosen that energy is delivered by the alternator at unity power factor. Specification 16443/15 also is referred to.

Title: Improvements in and relating to locks
IPC: E05B63/00
Filed: 1951-01-30
Abstract: 693,855. Locks. UHER, E. Jan. 30, 1951 [Feb. 7, 1950 ; March 21, 1950], No. 2287/51. Class 44 A lock comprises a slidable bolt 10 formed with a rack profile 10a, a cylindrical member 1 e.g. a barrel lock mounted in a through bore of the door and having an extension 3 providing a projecting arm spaced from the cylinder, a rotary control member 6 having means 20 for driving the rack which slides without clearance (such as might allow picking or forcing of the lock) between the arm 3 and the control member, the control member being adapted to drive the rack over a definite angle of rotation outside which it locks the rack and means for rotating the control member. In the form shown in Figs. 1, 2, 3, there are two cylinder locks 1, 5 connected by a bridge forming the extensions 3. The control member 6 is in the form of a pair of discs mating to provide a central boss 18 having a flat face 19 and a driving pin 20. The bolt comprises a profiled strip 10 having teeth 17 with gaps 21 there-between, a pair of bolts 8 being mounted either side of the strip 10 so as to slide therewith in the gap 7 provided by the extensions 3. The control member has a central opening 30 in which may be. engaged either of a pair of pivotally connected elements 67 to connect the control member with one cylinder lock or the other. The thickness of the strip 10 is equal to the gap in the control member. When the control member is in the locking position of Fig. 2 the curved surface of the boss 18 fits in the curved profile of a tooth 17 so that the control member cannot be rotated by pressure on the bolt. Rotation of the relevant lock by the key causes the control member to turn until the pin 20 engages in a slot 21 the tooth 17 being freed by the flat 19 or the boss 18 so that it may slide (as shown in Fig. 8, illustrating another embodiment). Complete rotation of the lock engages the boss 18 with an adjacent tooth 17 so that the bolt is locked in another position. In the form of Fig. 8 the bolt is formed with teeth 17a, 17b for co-operation with parallelly mounted cylinder locks 36, 37. In this case it is first necessary to turn the boss 44 of lock 37 to the releasing position as shown and then turn the boss 18 and pin 20 of the lock 36 to displace the bolt 49 to the releasing position. The cylinder locks are retained in bores in a mounting block by the teeth 17a, 17b and may be removed and replaced by different locks when the bolt is displaced to a projected position beyond the normal.

Title: Improvements in and relating to refrigerating plants
IPC: F25B1/053
Filed: 1935-01-25
Abstract: 440,593. Refrigerating. AKT.-GES. BROWN, BOVERI, & CIE, Baden, Switzerland. Jan. 25, 1935, No. 2559. Convention date, May 30, 1934. [Class 29] [See also Groups XXVI and XXXV] Compression machines.-A throttle valve 4 in the suction of a turbo-compressor 1 of an electrically driven machine is held closed during the starting-up period by means dependent on the pressure of the evaporator 2, which has risen during an idle period, until the evaporator pressure has sunk to a normal value, whereby overloading of the motor is avoided. In the arrangement shown in Fig 1 the evaporator pressure is transmitted through conduits 9, 10 to a bellows chamber 7 on the actuating rod 6 of the throttle valve, the exterior of the bellows being subject to the pressure of the condenser space 3 of the machine or to that of the atmosphere. A baffle or throttling device 11 is located in the pipes 9, 10 to damp down fluctuations of pressure. The evaporator pressure is assisted by a spring 17 and the pressure is adjustable by a hand wheel 18, which may also be used for actuating the throttle directly. The throttle may be actuated, under evaporator pressure control, by oil or water pressure, or, as shown in Fig. 2, by a reversible electric motor 28. In this arrangement the evaporator pressure is transmitted through conduits 9, 11, 10 to a bellows chamber 19 around an adjustable tappet rod 20 adapted to engage one or other of arms 22, 23 of a forked switch arm controlling the circuit of the motor 28 and also the circuit of a thermostat 35 in the evaporator. After the shutting down of the machine the increased evaporator pressure moves the tappet rod to the left and closes the circuit of motor 28 at contacts 25, 27, to close the throttle valve. When, after restarting of the machine, the evaporator pressure has fallen the contact at 25 is opened and that at 24 is closed to bring the thermostat 35 into action for controlling the motor circuit at 36, 39, 37 to maintain a constant pressure and temperature in the evaporator,

Abstract: 1463861 Automatic control of fuel injection in IC engines REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 18 Jan 1974 [19 Jan 1973] 02560/74 Heading G3N [Also in Division F1] A fuel injection system includes a supply of pressure fuel which is controlled by a pair of differentially connected flow control valves connected to the inflow and outflow of a distributor which supplies the fuel to the individual mechanical injectors and means to control the valves in accordance with the mass air-flow into the engine. In the system shown, the flow control valves 5, 6 are responsive to the frequency of the output signal from respective converters 44 which are supplied from air-flow measuring device 43 which has a differential electric output I 1 , I 2 . The valves 5, 6 are connected respectively to a pressure pump and supply tank so that fuel circulates through distributor 4 and are of the type having a conical control port so that the pressure drop is independent of flow-rate. A differential pressure transducer 9 measures the difference in flow-rates and this is compared in comparator 28 with a calculated value and any error used to adjust the frequency of converters 44 to correct the flow-rate.  It is calculated that the product of the sum and difference of the differential current signals I 1 , I 2  at any time provides a reference value for the comparator 28 as long as the input supply to the meter 43 is proportional to the sum I 1  + I 2  and this is used in control 34 to supply pulse converter 33 supplying the meter 43.
Patent GB-672136-A (GB)
Title: Process for the production of closed cell cellular bodies
IPC: C08J9/04
Filed: 1949-01-31
Abstract: Cellular bodies are produced from non-vulcanizable organic high molecular weight thermoplastic substances, e.g. polymers or copolymers of vinyl chloride, styrene or cellulose esters, by mixing with a gas liberating agent, e.g. diazoaminobenzene and ammonium nitrite, which decomposes irreversibly on heating to liberate a gas which diffuses slowly through the walls of the closed cells formed. The mixture is filled completely into a closed space under external pressure and is heated so that the mass assumes the condition requisite for solution of the gas liberated, which dissolves under high pressure.  The hot mass is then cooled to a consistency which allows it to expand under internal pressure without rupture of the cells, upon release of the external pressure.  In a modification, the mass is cooled till solid, the external pressure released and the mass then heated to a suitable temperature for cell formation.  Other substances such as tricresyl phosphate, tetra-, penta-, and hexa-methylene and p-phenylene diisocyanates may be added.  The surface may be hardened by after treatment with alcohols, glycols, glycerine, water, acids, ammonia, and amines in liquid or vapour form.  The Specification as open to inspection under Sect. 91 comprises also the use of ethylene isocyanate and iron and zinc oxides as additional agents; this subject-matter does not appear in the Specification as accepted.

Abstract: 419,410. Yielding clutch - plates. BORG & BECK CO., and REED, H. V., 6558, South Menard Avenue, Chicago, U.S.A. Jan. 29, 1934, No. 3024. [Class 80 (ii).] In a cushioned clutch-plate for a motor vehicle in which the friction-member 4 is drivingly connected with the hub 1 by coilsprings 9, the springs take effect in stages in either or both directions of drive. The springs are accommodated, with or without initial compression, in registering holes 25 &c. in the hub 1 and in the friction-member 4, which latter is connected to a side-plate 5 by rivets 6 which pass through arcuate slots in the hub to limit deflection. In Fig. 10, the openings 26, 27, 28 in either member 1 or 4 are elongated in progressively increasing amounts on one side of their centre-lines so that the springs act successively when the engine drives and simultaneously when it transmits braking torque. The holes 26 &c. may be cut away also on the other side of their centre-lines to give successive action in both directions of drive. A two-stage form uses two groups of four springs each. In the form shown in Fig. 13, the openings 30 are all of the same size, but those in one member 1 or 4 are arranged in symmetrical groups or pairs which are unequally spaced, those in the other member being equally spaced, so that the initial compression of one pair 9 of springs balances the oppositely acting compression of the other pair 9<a> and the pairs act in stages in both directions. The friction rings 8 or sections may be loose or secured to the member 4 and the springs 9 are retained on each side by clamped rings 10. Deflection curves are given.
