Title: Improvements in or relating to sound recording systems
IPC: G11B5/86
Filed: 1944-05-16
Abstract: 580,695. Sound recording systems. WESTERN ELECTRIC CO., Inc. May 16, 1944, No. 9348. Convention date, May 21, 1943. [Class 40 (iv)] In a sound recording system in which the outputs from a number of records are combined in suitable proportions and re-recorded, the settings of the manually - operated volume control associated with each reproducing system are recorded as perforations on a tape during experimental re-recordings, the tape being used with or without modification during the final re-recording either to control the volume of sound from the reproducer concerned or to give indications whereby the volume may be controlled manually. A single set of perforations may indicate the settings of all the volume controls. As shown, each setting of a volume control 5 associated with a reproducer 1 causes the operation of a different combination of magnets 23 ... 27, each magnet on operation bringing a punch actuating member 64 into association with its punch. A motor 31 running synchronously with the reproducer motor drives a cam 34 which periodically gives an impulse to a magnet 36 to cause the tape to be perforated by the selected punches and stepped on by a pawl 39, and also to a magnet 48 which steps round a ratchet-disc. When the latter has made a complete revolution, it actuates a magnet 59 which operates a register of the amount of film wound off and causes the amount to be printed. The tape is wound up by a motor 85 which is stopped when the amount of slack is sufficiently small. In the final re-recording, the tape is fed over feelers which control contacts 124 to 128 to energize appropriate combinations of potentiometercontrolling relays 105 to 109. These relays lock up and are unlocked by cam-operated contacts 132 which are operated by the tapedriving motor and open as a new set of perforations is coming to the operative position. Specification 548,557 is referred to.

Filed: 1933-03-28
Abstract: 413,081. Converting. SOC. ANON. HEWITTIC, and DEMONTVIGNIER, M., 11, Rue du Pont, Suresnes, Seine, France. March 28, 1933, No. 9353. Convention date, April 27, 1932. Addition to 410,880. [Class 38 (ii).] In an arrangement for varying the ignition instant in a vapour-electric discharge device 1 by means of grid potentials derived from auxiliary rectifiers 15, 16, 17, the circuits of which include resistances and variably-saturated inductances 12, 13, 14, as described in the parent Specification, the auxiliary rectifier circuits which are fed by windings 9, 10, 11 on the transformer 8 feeding the main rectifier have a part in common which includes an inductance 18 and a resistance bridge 19, 20. The latter is used to supply manually regulatable current to windings 30, 31, 32 connected in open delta and adapted to vary the saturation of the cores of the inductances 12, 13, 14. Automatic variation of the saturation of the cores in response to load conditions may be introduced by an additional set of windings 33, 34, 35 connected across a shunt 36 in the load circuit of the main rectifier. Thus a wide range of variations (discussed at length in the Specification) in the characteristic of the main rectifier, may be produced by utilizing the voltage variations appearing across the terminals of the auxiliary rectifiers in conjunction with a D.C. voltage derived from a potentiometer 27 across the main rectifier terminals to energize the grids 21, 22, 23 of the main rectifier. A modification is described with reference to Fig. 3 (not shown), suitable for a single phase full wave rectifier. A plurality of such arrangements and combinations thereof with three phase arrangements, as shown in Fig. 1, may be used for a larger number of phases.

Title: Molecular Sieve for Vacuum Circuit Interrupter
IPC: H01H33/668
Filed: 1969-02-21
Abstract: 1,192,897. Vacuum switches; gettering. WESTINGHOUSE ELECTRIC CORP. 21 Feb., 1969 [13 March, 1968], No. 9500/69. Headings H1D and H1N. A molecular sieve material 64 is contained within the evacuated envelope of a vacuum switch to absorb any gases or particles produced during arcing or leaking into the envelope. Suggested materials are the zeolites (aluminosilicates); activated carbon or charcoal; activated alumina; silica gel; certain reforming catalysts such as platinum on alumina; sintered porous-metals such as are used for filters; and metallic felt. These materials are more effective at low temperatures and therefore may be cooled by flowing liquid 97 such as liquid ammonia, nitrogen or the inert gases of Group O or by solid carbon dioxide. The vacuum switch comprises a metal envelope 44, insulated from a moving contact member 16 by a tubular insulator 32 and from a fixed contact member 12 by an insulating seal 45; the moving contact is sealed to a metal end plate 24 by a bellows 20. Supported with the envelope is a shield 50 surrounded by a jacket 68 containing the liquid coolant; which is also supplied to the hollow interiors of the contacts. Inside the shield 50 is a gauze screen 11 containing lumps or pellets 64 of the molecular sieve material. The irregular form is adapted to trap particles and prevent reflection of radiation back into the arc. The gauze 11 may be corrugated (Fig. 3, not shown), to further increase the irregularity. In a modification (Fig. 4, not shown), the molecular sieve material is located outside the cooling jacket 68 and therefore only serves to absorb the gas particles. The liquid cooling arrangements may be omitted (Figs. 2, 5, not shown), and the invention may be applied to a vacuum switch having a liquid gallium contact (153) (Fig. 6, not shown).

Abstract: 654,674. Voice-frequency signalling. STANDARD TELEPHONES & CABLES, Ltd. April 9, 1948, No. 9944. [Class 40 (iv)] [Also in Group XL (c)] The operation of a relay forming part of a voicefrequency signal receiver as described in Specification 654,639 effectively prevents the signals from passing into a channel beyond the receiver by reducing the transmission properties of either a thermionic valve, a negative feed-back amplifier or a saturable reactor. As shown in Fig. 1, the closing of relay contact 14 increases the positive potential on the cathode 2 of a pentode valve 1, an automatic bias condenser 8 providing a smooth transitional increase in attenuation. Embodiments are also described, Figs. 2 to 5 (not shown), in which the operation of contact 14 changes the potential applied to any one of the grids or to the anode of a pentode valve, a transition smoothing condenser being provided in each case. In an application to voltage or current negative feed-back amplifiers, Figs. 6 and 7 (not shown), the feed-back is increased by operation of contact 14. In a further embodiment, Fig. 8, substantial attenuation is introduced into the channel by disconnecting the D.C. bias of saturable reactors 50, 51 at contact 14, the windings of each reactor being suitably arranged so that inductive surges in the line due to the removal of bias from each reactor are neutralized. Specifications 651,457 and 651,464 also are referred to.
