Title: Impelling wheel for particulate material
IPC: B24C5/06
Filed: 1972-09-08
Abstract: 1371278 Blasting VACU-BLAST Ltd 23 July 1973 [8 Sept 1972] 41825/72 Addition to 1320641 Heading B3D The impeller wheel described in Specification 1,320,641 is modified by the tubes 1 being located in position by centrifugal force during rotation of the wheel and by resilient means 16 at least when the wheel is stationary. The tubes 1 may be of ceramic material and are mounted in holders 11 having end flanges 12 to retain the tubes against the centrifugal force. Rubber or plastics washers may be disposed between the ends of the tubes and the flanges. Each holder has a pair of lugs 13 which, when the holder is rotated through 45 degrees about its axis from its final position permit the holder to be inserted between pins 15 extending between the front and rear plates of the wheel. The holder is then rotated through 45 degrees to its final position wherein the lugs engage grooves (14, Fig. 1, not shown) in the pins. Centrifugal force acts, during rotation of the wheel, to urge the lugs against the pins but, while the wheel is stationary, a spring 16 attached to a collar (10) acts on a washer 17 which presses against the inner end of the holder. The tubes may be rotated to present fresh parts of the tube wall to the particles when a part has worn. To determine the amount of rotation, a cut-out 20 on a shoulder of the tube can be selectively aligned with cut-outs 19 on the inner end of the holder and engages a key 21 on the washer 17. A seal (22) is provided where the tubes pass through apertures in the collar (10). Instead of a thin seal (22) a thick lining of plastics foam material may fill the voids between the tubes and collar. In another embodiment, the springs 16 and washers 17 are replaced by a moulded rubber or plastics sleeve or bellows.

A., 66, Harpst Street, Ann Arbor, both in Michigan, U.S.A. April 17, 1934, No. 11532. Convention date, May 1, 1933. [Class 7 (iv)] In systems in which a condenser 12 is discharged through the primary winding 26 of a transformer, a tube 16 with spaced electrodes permits discharge only when the condenser is charged to a predetermined voltage. The condenser is shunted across an interrupter 14 in series with a battery and inductance L, but the positions of the condenser and inductance may be interchanged. One microfarad and .006 henry are suitable sizes for these members. The electrodes of the tube 16 have a low work function and may be composed of an alloy of nickel 46 per cent, copper 46 per cent, chromium 4 per cent and barium 4 per cent, or chromium may be omitted. With a tube having a heated electrode, materials having higher work functions may be used. Greater accuracy with regard to the discharge voltage may be obtained by interposing a third electrode biassed by con. nections to a battery. Photoelectric characteristics which occur when using low workfunction materials and promote discharge at a lower voltage may be avoided by making one electrode as a hollow cylinder surrounding the other. A rectifier valve may be included in the circuit of the condenser 12, and a small condenser may shunt the interrupter 12. Specification 430,598 is referred to.

Abstract: 1524870 Depositing metal conductor patterns PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 Oct 1975 [25 Oct 1974] 43342/75 Heading C7F [Also in Division H1] A conductor pattern comprising portions of deposited conductor separated by a distance <10 microns is formed on a substrate such as a semiconductor by vacuum depositing or sputtering the conductor or conductors from at least two sources so that the material is directed from different directions at an apertured mask above the substrate. The substrate is preferably a semi-conductor at least partly covered with an insulating layer of SiO 2 , Si 3 N 4  or Al 2 O 3  and the deposited conductors are used as electrodes in semi-conductor devices such as MIS, IGFET, CTD, and CCD structures.

In the base-station receiver the received suppressed carrier signal is processed by generating an estimated digital signal having a clock frequency, which is mixed with the received signal, the mixed signal is squared in a frequency doubler circuit, the squared signal then being brought progressively into phase with the estimated digital signal to effect correlation of the estimated signal with the received signal of unknown time delay.
