Abstract: 623,210. Grinding and polishing. ASSOCIATED DEVELOPMENT & RESEARCH CORPORATION. Oct. 10, 1946, No. 30303. Convention date, Oct. 10, 1945. [Class 60] [Also in Groups XXII, XXIV and XXXV] A power-driven domestic appliance for mixing, knife-sharpening &c. comprises a motor connected by a flexible shaft to a tool-holder in which a plate-type clutch is fitted. The motor 10, Fig. 1, is controlled by a rheostat switch 16, and, through idler gears 21, 22, Fig. 5, and an internal gear 24, drives a shaft 27 within a flexible sheath 17 having a flared end held by a nut 32 against a neck 31 on a cover plate 30. The tool-holder consists of two halves secured together to enclose a clutch barrel 38, Fig. 2, and clutch-operating levers 65, 64. Clutch plates 45, 51 are slidably engaged by means of lugs with the clutch barrel 38 and the shaft 27 respectively and, until released by the clutch levers, are pressed together by a spring 52 to transmit the drive to a shaft 56 having a tool socket 57.

Patent GB-961671-A (GB)
Title: Bearing composition
Inventor: RULON-MILLER ROBERT
IPC: F16C33/04
Filed: 1960-09-12
Abstract: Bearings for relatively moving surfaces consist essentially of a homogeneous mixture of (i) 50 to 80 vol. % polytetrafluoroethylene, (ii) glass, talc, mica or aluminium silicate and (iii) aluminium, molybdenum, copper, lead, lead oxide or cuprous oxide, the ratio of (ii):(iii) being from 1:1 to 2:1 by volume.  Glass, when used, is preferably milled fibre but may be in the form of ground glass or beads.  The preferred form of aluminium silicate is a ceramic fibre. In all the examples the mixture is sintered and in one procedure the hot bearing is first formed in an oversize mould then forced into a mould of the correct size and quick chilled; this procedure is stated to result in a lower coefficient of friction as well as ensuring a proper size uniformly solid bearing. Specifications 671,149 and 779,442 are referred to.

Abstract: 480,383. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO. Nov. 17, 1936, No. 31427. Convention date, June 1. [Class 130] In order to prevent irregularities or choking in a continuous-rod machine, vibratory movement is imparted to an element by which the stream of tobacco is confined and compacted to cigarette-rod size. As shown, a rod-forming tongue 14 is supported at one end by a bracket 13 encircling an eccentric 12 on the shaft of a motor 11, and at the other end by a flat spring 16 secured to a bar 17. The tongue 14 is thus vibrated at an angle to the direction of travel of the tobacco on the tape 18. In a modification, Fig. 4, the forward end of the vibrating tongue is provided with a projection 15a guided by a slotted member 20, and the downward movement of the tongue is limited by means of a lug 22 on the tongue provided with an adjustable screw 23 engaging one of the side bars 21. The tongue may have a stepped or serrated surface to impart a positive forwarding and compacting action on the tobacco, and its forward movement may be at a speed greater than the speed of travel of the tobacco stream:

Title: Improvements in or relating to electrical devices for automatically interrupting radiation
IPC: H05G1/44
Filed: 1934-11-05
Abstract: 442,389. Discharge apparatus. MULLER AKT.-GES., C. H. F., 24, R÷ntgenstrasse, Hamburg, Germany. Nov. 5, 1934, No. 31776. Convention date, Nov. 6, 1933. [Class 39 (i)] [See also Group XX] A device for automatically determining the duration of radiation comprises a vacuum discharge tube controlling the switching on and off of the radiation, the charge on the grid of the discharge tube being determined by the charge of a condenser which discharges through an ionization chamber, the characterizing feature being that the condenser is negatively charged through the grid and cathode of the vacuum discharge tube. In Fig. 2 the switch 11 is operated by the current through the discharge tube 6 which has an anode 10, a grid 8, and a cathode 5. A switch 12 connects the cathode either to the negative end of a source of voltage 3 whereby the condenser 2 is charged negatively via the grid 8 ; or to the grid through the condenser 2 whereby a negative charge is imparted to the grid. As the radiation ionizes the gas in the chamber 1 the charge leaks away and the current through the discharge tube gradually increases until the switch 11 is operated to interrupt radiation. In Fig. 3 the ionization chamber functions as the condenser and is also made integral with the discharge tube. The condenser is charged from the transformer secondary 19, rectifier 20 and rheostat 23, and by connection of the switch 12 to the tapping 24, the electrode 17 and grid 18 are made negative with respect to the cathode 22. The flow of current through the discharge tube 14 brings about a potential drop in a resistance 26 whereby the grid of the triode 29 is made positive, the anode current of which operates the relay switch 32. In order to lengthen the surface leakage path and improve the insulation, the ionization chamber is provided with a support extending inwardly and surrounded by a hood shaped inner electrode. An interfused metal ring connects the two walls that support the electrodes and this ring is connected to a point having a negative potential, e.g. the end of the resistance 23. Specification 339,215, [Class 98 (i)], is referred to.
