Patent GB-921263-A (GB)
Title: Improvements in or relating to alternating current frequency meters
IPC: G01R23/02
Filed: 1960-03-31
Abstract: 921,263. Frequency detectors. SANGAMO WESTON Ltd. March 31, 1960 [April 1, 1959], No. 11425/60. Class 40 (5). In a frequency meter the frequency is applied to a transformer primary 23 series-connected to a shunt resonant circuit 26, 27 with output connected to a centre tap of the transformer secondary 28, so that at the resonant frequency the secondary outputs are the vector sum of two voltages differing by 90 degrees but at higher frequencies the 90 degrees phase difference alters and the otherwise equal vector sum outputs differ in amplitude. The latter are then applied to opposite junctions of a rectifier bridge 34-37 with all rectifiers connected in the same sense round the bridge, equal load resistors 43, 44 being connected across the other junctions and a frequency indicator meter 12 across the resistors with range, e.g. 380-420 c/s. starting from the resonance frequency. Rectifier pairs 34, 36 and 35, 37, respectively, of the bridge conduct alternately. A further voltage from the input may be applied through a resistor 49 to the transformer secondary centre tap to compensate for any departure from 90 degrees of the sum voltages at resonance due to the rectifier loading of the resonant circuit, or to adjust the lower frequency limit of the meter. A saturable input transformer 14 rejects input voltage variations and any harmonics generated are rejected by an R-C filter 20-22. A choke 16 and resistance 17 limit the current in the input transformer primary.

Title: Improvements in and relating to liquid break electric switches
IPC: H01H33/75
Filed: 1933-04-20
Abstract: 402,990. Liquid-break switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) April 20, 1933, No. 11589. Convention date, April 20, 1932. Addition to 402,927. [Class 38 (v).] In the liquid-break switch described in the parent Specification, in front of the orifice of the extinguishing chamber and within the expansion chamber is provided a partition inclined to the axis of the extinguishing chamber and having an opening for the passage of the contact rod, the partition serving to divert the vapour and liquid during the opening of the switch into the expansion chamber. As shown in Fig. 1 in which the expansion chamber 2 is mounted at right angles to the extinguishing chamber 1 a partition 5 is formed within the expansion chamber inclined at 45‹ above the entrance to the extinguishing chamber so that the vapour and liquid emerging from the latter during the opening of the switch is diverted as shown by the lines into the expansion chamber. The contact rod emerges through holes 6, 4 in the partition and the wall of the expansion chamber and in view of the diversion of the gas and liquid only a small portion of the gas produced by switching emerges into the atmosphere. In a modification (Fig. 2, not shown), openings may be arranged from the space behind the partition into the expansion chamber so that the escape of gas into the atmosphere is still further reduced.
Patent GB-400259-A (GB)
Title: Improvement in process of and apparatus for refining metal
IPC: C22B15/00
Filed: 1932-04-22
Abstract: 400,259. Metalmelting furnaces. SUMMEY, D. L., Waterbury, Connecticut, U.S.A. April 22, 1932, No. 11595. Convention date, May 8, 1931. [Class 51 (ii).] In casting ingots, &c., from refined metal such as copper, aluminium, nickel, zinc, magnesium and their alloys, the metal is charged in continuous increments into a vessel, without contamination of fuel gases and while fully protected from air, and, if necessary, reduced by a medium incapable of leaving harmful residue, the vessel being substantially gas-tight and filled with non-oxidizing gas at superatmospheric pressure. Charges 10 of crude metal may be introduced by a conveyer 11 through a lock chamber 12 into an oven 15 heated by an electrical resistance 16. The heated charges 10 fall into a melting furnace 20 heated by electric induction heaters 29 which also serve to stir up the metal. Hydrogen, carbon-monoxide or other gas is introduced at 21 and exhausted at 23 to remove the sulphur or other impurities and some of the oxygen in the metal. The molten metal may be covered with a layer of carbon, and, instead of special gases, a small amount of air may be admitted through the door 13 to remove sulphur. The purified metal is discharged through an articulated hood 25 into a furnace 30 also heated by electric induction but controlled by relays R2, R<1> and a pyrometer 51 cased in silicaalumina. The metal is covered by a layer of carbon C or the furnace is supplied at 31 with carbon-monoxide, nitrogen, or other deoxidizing or inert gas or both, or carbon with small volumes of air may be used to protect the metal and, when necessary, remove oxygen and hydrogen. The oxygen-free metal is then poured, through an articulated hood 33 with observation windows 47, 48, 49, and, if desired, through a strainer 41 enclosed in a casing 42, into a mould 43 which is coated with bone black and filled with the gases by removing the bottom 45 for a time. The metal is poured slowly and the moulds may be cooled to avoid trapping air and ensure cooling from the bottom up. The hood 33 and casing 42 may have electric heaters 39, 44 and are supplied with gas at 57, 46 or from the furnace 30 through passages 38, 50. The furnace may have a trap 37 to retain slag. When the mould is detached the metal therein is covered with carbon, barium chloride, calcium chloride, a heavy gas or slag. In a modification the oven 15 and furnace are dispensed with and pure copper cathodes are fed direct to the furnace 30 through a door 55. In other modifications the furnace 20 or the furnace 30 is omitted. If high conductivity rather than freedom from oxygen is required in copper a small amount of air or oxygen may be admitted by the pipe 57 during pouring. If desired an exit for gases need not be provided, existing cracks serving for excess of gas to escape and the gas pressure being maintained above that of the atmosphere.

Title: Improvements in telephonic transmission systems using multiple channel carrier currents
IPC: H04J1/04
Filed: 1945-05-11
Abstract: 632,778. Multiplex systems. SUEUR, R. C. May 11, 1945, No. 11846. Convention date, Nov. 25, 1943. [Class 40 (iv)] The voice frequencies of one channel A1 and side-band frequencies obtained by modulating a carrier wave f1 with voice frequencies B1 of a second channel are transmitted together as a group. The filter F1 accepts the original frequencies (0-4 kc/s.) and F2 accepts the upper side-band (4-8 kc/s.) produced when f1 is modulated by B1 in the modulator M1. A carrier f2 is modulated by the group frequencies in a modulator M2 and the lower side-band accepted by a filter F3 is applied with five similar groups A2, B2 ... A6, B6, making twelve channels in all, to a group modulator M3, where a carrier f3 is modulated. Before amplification at A and transmission to line L, the lower band is finally selected by a filter F4. The operations are reversed at the receiver. The twelve channels occupy a band of frequencies of 48 kc/s. between 60 and 108 kc/s. In a modification, the groups are fed through an additional stage of modulation before they are assembled together in one band.

A magazine for storing hypodermic needles of the kind described in Specification 802,351 comprises means for supporting them horizontally so that they may be withdrawn without contamination. The member for supporting the needles is preferably in the form of a disc 4 having a flanged rim in which the hubs 2 of the needles 1 are carried in circular holes. A vertical slots extends from each hole to the lower edge of the flange so that the rear part of a needle may be passed to or from a hole in the flange without the point coming into contact with it. The needles are retained in position either by the resilience of the metal of the disc 4 or by additional spring clips gripping the hubs 2. Several such assemblies are mounted on a central pillar 8 in a container 10, holding sterilizing fluid, and the container has a cover 13 and handle 14. When needles are to be used, a disc 4, carrying the needles, is withdrawn and placed on a table clamp (see Fig. 3, not shown). The needles are then protected from anything dropping on to them above, by the disc 4, and the syringe of Specification 802,351 may pick up a needle without any part of it being touched.
