Title: Improvements in or relating to electrical equipment
Inventor: HANSEN ELMER FREDERICK
IPC: H02K13/00
Filed: 1956-02-01
Abstract: 783,085. Lubricators. GENERAL ELECTRIC CO. Feb. 1, 1956, No. 3256/56. Class 12 (3). [Also in Group XXXV] Electrical equipment such as a dynamo-electric machine for use at high altitudes is provided with lubricating means for reducing brush-wear, each brush-holder 20 having a cylindrical chamber 42 communicating with a sealed space 29 about the commutator segments 24 and housing a cartridge for generating lubricating vapour. The vaporizable substance, such as liquid-saturated wool or a vaporizable solid, may be disposed within a perforated or porous container 41 in the form of a cylinder spaced from the wall of the chamber 42, the heat from the brushes being conducted through the metal of the members 20 to the receiving chambers. Each cartridge is supported by flanged end-caps 44, 45, the diameter of which is slightly less than the bore of the chamber so that the lubricating vapour may be developed from the entire curved surface of the cartridge. The container 41 may be omitted if the vapour-producing substance is sufficiently rigid. The cartridge may comprise a number of separate washers of vapour-forming material with a centre post 46 interconnecting the endcaps and a hook 47 for easy removal of the cartridge. A threaded sealing-plug 48 engages threads in each member 20 and is securely held in place by cotter-pin 49. Specifications 764,765 and 783,084, [both in Group XXXV], are referred to.
Patent GB-740207-A (GB)
Title: Improvements in or relating to radioelectric distance measuring systems
IPC: G01S13/82
Filed: 1954-02-04
Abstract: 740,207. Radar. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Feb. 4, 1954 [Feb. 4, 1953], No. 3325/54. Class 40 (7). A radio distance measuring system consists of a frequency-modulated radar apparatus and a co-operating responder comprising a quenched oscillator which is synchronized by the received radar signal at the (or each) distant object. In one embodiment frequency-modulated signals are generated by unit 3 and radiated by antenna 5. At the responder a quenched oscillator is coupled to a transmitting and receiving aerial and also to a quench oscillator having a waveform vg. When the wave vg reaches level vs the quenched oscillator breaks into oscillation and produces a burst of oscillations as shown at T. Its tuned circuit is arranged so that oscillation takes place at about the carrier frequency of unit 3 but without the reception of synchroniz. ing signals the phasing of these bursts is random. As soon as the responder receives working strength signals from the radar, however, these serve to synchronize it so that each oscillation is synchronized at its commencement with the received signals and continues at the same frequency. The bursts of oscillation radiated by the responder are received by aerial 6 at the radar and mixed in mixer 7 with the signals from generator 3 and then amplified at 8 and detected at 9 to give a beat frequency output. This is fed to a standard frequency-modulation radar distance indicator 10. The period of the radar frequency modulation must be large compared with the quenching period. A single radar can co-operate with a plurality of responders, each of which has a different quenching frequency. The radar receiver requires the same number of units 8-9-10 as there are responders. These are fed from a common mixer 7 and the amplifier stages 8 are tuned to different ones of the quenching frequencies so as to separate out the received signals (Figs. 5 and 6, not shown). A suitable quenched oscillator circuit is described with reference to Fig. 7 (not shown).

Title: Improvements in or relating to the preparation of sulphurised terpenes
Inventor: GREENWOOD JOHN
IPC: C07G99/00
Filed: 1954-02-11
Abstract: Sulphurized terpenes are prepared by heating a terpene or mixture of terpenes with elemental sulphur in the presence of a diluent comprising a steam distillate obtained by the steam distillation of a previous terpene sulphurization reaction mixture.  Terpenes specified are dipentene, carene, alpha pinene and camphene.  A sulphurization accelerator such as tetramethylthiuram-disulphide, mercaptobenzthiazole or diphenylguanidine may also be present.  The sulphurization is conducted at 100 DEG  to 200 DEG  C., using 1 to 3 gram-atoms of sulphur per mol. of terpene in the presence of 10 to 50 per cent by weight of steam distillate as diluent based on the sulphurization reaction mixture.  On completion of the reaction, the reaction mixture is steam distilled to yield the sulphurized terpene and a steam distillate which may be used in a subsequent sulphurization. The steam distillate may be treated to remove any unreacted hydrocarbon before use as a diluent.  The product may be treated after or during the steam distillation with an activated clay such as fuller's earth.  In examples: (1) free sulphur, commercial dipentene, mercaptobenzthiazole, diphenylguanidine and a steam distillate from a previous substantially identical sulphurization of commercial dipentene were heated until evolution of H2S had ceased, fuller's earth was added, the mixture was steam distilled and the residual mixture filtered to yield the sulphurized terpene; (2) an exactly similar mixture, but using the steam distillate from (1) was heated, steam distilled and the residual product heated with fuller's earth and filtered to give the sulphurized terpene.  Specifications 688,293, 703,631 and 750,094 are referred to.
