Title: Quick-action automatic electric circuit-breaker
IPC: H01H71/26
Filed: 1933-06-29
Abstract: 407,853. Automatic circuit-breakers and electromagnetic switches. MASCHINENFABRIK OERLIKON, Oerlikon, near Zurich, Switzerland. June 29, 1933, No. 18517. Convention date, July 5, 1932. [Class 38 (v).] In a quick - acting automatic circuitbreaker having oppositely-acting holding and releasing electromagnets, the releasing coil, energized by the load current, detaching the armature from the holding coil to open the circuitbreaker, in order to prevent an increase in the holding current during release consequent on the diminution of flux in the magnetic circuit of the holding coil, caused by the movement of the armature, which might cause an undesired reclosure of the circuit breaker, a second coil in series with the holding coil is wound on the releasing electromagnet. An E.M.F. is induced in this coil during release by the increase in flux of the releasing electromagnet, this E.M.F. being opposite to that induced in the holding coil as the result of diminution of the holding flux. As shown in the Figure the holding coil 4 on the holding electromagnet 2 is in series with the second coil 8 on the releasing electromagnet 6 which is energised by a coil 9 in series with the main circuit. When the armature 3 commences to move due to excessive current in the coil 9 the voltages induced in the coils 48 due to changes in flux of the holding and releasing electromagnets oppose each other so that no appreciable increase in the holding current occurs and no tendency for a premature reclosure of the circuit-breaker will be present. If desired the momentary E.M.F. induced in coil 8 may exceed that induced in coil 4 so that a temporary reduction of the holding current may take place. The release of the circuit-breaker may be further assisted by a coil 5 on the holding electromagnet which is in series with the coil 9 in the load circuit and which is wound to oppose the holding electromagnet 4. A constantly acting force indicated by K may be provided to assist the releasing movement of the circuit-breaker.

Title: Improvements in or relating to spark plug
IPC: H01T13/34
Filed: 1943-11-09
Abstract: 578,285. Spark-plugs. FIRESTONE TIRE & RUBBER CO. Nov. 9, 1943, No. 18609. Convention date, March 6. [Class 7 (iv)] A spark-plug comprises a porcelain insulator 42 enclosing a two-diameter central electrode which is located by plastic cementitious material which is prevented from flowing into the lower portion of the insulator, threaded means being provided for effecting longitudinal movement of the electrode into the insulator during assembly of the plug. In one form, Fig. 1, the insulator 11 supported by soft metal gaskets 12 has a multiple-threaded upper bore 19 counter-bored at 18 and a smaller smooth lower bore 22, the bores being separated by a taper shoulder 21. The electrode has a tip portion 24 which is a loose fit in the bore 22, and is welded to a threaded upper portion 25 having preferably half the number of threads in the insulator. The upper portion has a flange 28 and screwed terminal portion 29. In assembling the plug, a slidable metal sweeper collar 30 is placed on the part 22 in a lower position than its final one and 'the electrode, covered with cement inserted from the top. After the collar 30 is seated the portion 24 slides therethrough and is cleaned of cement. During the screwing home of the electrode superfluous cement escapes along the unoccupied threads and is removed. Finally the flange 28 seats over the cement-filled counter bore 18. Alternatively the cement may be injected after the sweeper collar is seated. In a modification the sweeper collar is formed by a part sphere of soft deformable metal such as copper or brass which is cast on to the lower electrode and the threads are of such shape that helical spaces are left to receive the cement. In another modification, Fig. 4, the upper electrode portion 42 has a single thread at 45 and a slidable sweeper collar 30 is used. The threads of the insulator part 50 are truncated to leave a helical recess for the upward escape of cement during assembly. In another modification, Fig. 5,' the insulator has a steep-pitch dual-threaded part 57 co-acting with opposed lugs 62 on the electrode. The electrode also has a thread 63 which serves to improve the bond between the cement' and the electrode. In a further modification the electrode has a short thread at its lower part co-acting with a similar short thread in the insulator and serving instead of a sweeper collar to prevent flow of cement to the lower part of the insulator bore. In another modificattion the counter bore is provided with a deformable washer to assist in sealing the upper end of the porcelain aperture. The Specification as open to inspection under Sect. 91 describes a further modification, Fig. 8 (Cancelled) wherein an electrode having an integral collar 108 and slidable collar 109 is inserted from below in an insulator bored to form a shoulder 104 engaging collar 108. The collar 109 is positioned after inserting the electrode in order to compress the cement into the part 14. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the preparation of non-alcoholic carbonated beverages
Inventor: FRIENDSHIP KENNETH FRANCIS MON
IPC: B01F3/04
Filed: 1955-06-06
Abstract: 770,312. Preparing carbonated beverages. MEYER LIQUID, Ltd., [formerly LIQUID CARBONIC CO., Ltd.]. June 6, 1955 [June 25, 1954], No. 18713/54. Class 14(1) Non-alcoholic carbonated beverage is prepared by mixing water and syrup at about normal temperature, subjecting the mixture to carbonating and chilling operations 'under pressure and then allowing the mixture to settle under a lower pressure which is so regulated that it is sufficient to keep a specified degree of carbonation in the liquid. The mixture is supplied at normal temperature to a high pressure tank 1 from a mixing device as described in Specification 759,424 [Group II] and enters through an inlet 2 via a non-return valve 3. A pipe 5 delivers the mixture over the exterior surface of a carbonating cylinder 4 of porous ceramic material, carbon dioxide gas being supplied to the cylinder 4 from a pipe 7, regulating valve 8 and pipe 9. The main effect of the carbonating cylinder 4 is to release air from the mixture, which air is exhausted by a snift valve 10. The cylinder 4 rests upon a strainer 11 through which the mixture. passes to a pipe 12 and is then driven by a centrifugal pump 13 to the main carbonator 16, which by means of a restricted inlet and baffle means causes turbulence of the mixture during passage therethrough, carbon dioxide gas under pressure being admitted to the lower end of the device 16 from a pipe 17. The carbonated mixture then passes to a heat exchanger 19 for chilling so than any free carbon dioxide is absorbed by the mixture. The outlet 22 from the heat exchanger 19 has two branches, one 23 leaking through a non-return valve 24 to a second inlet 25 to the tank 1 so that the mixture can be re-circulated through the carbonating and chilling processes, the other branch 26 leading through a valve 27 and a pressure reducing valve 28 to a low pressure or beverage accumulating tank 29. The reducing valve 28 is regulated by a diaphragm in a casing 31 which is pneumatically actuated under the control of a valve 32 actuated by a float 33. Compressed air is supplied from the snift valve 10 by a pipe 34 leading to the valve 32 and by a pipe 35 leading from the valve 32 to the diaphragm casing 31. A predetermined level of carbonated liquid is thus maintained in the tank 29, the pressure in the tank 29 being kept at a lower level sufficient to retain the carbon dioxide in the mixturfe. For the preparation of less highly carbonated beverages, the tank 1 may be omitted and the mixture delivered directly under pressure to the carbonator 16, in which case there is no recirculation of the mixture. Specification 769,330 [Group XVII] also is referred to.
