Title: Cleaning machine for eggs and the like
Inventor: PALMER ROY MICHAEL
IPC: A01K43/00
Filed: 1963-04-17
Abstract: 991,049. Centrifugal separators. RICARDO & CO. ENGINEERS (1927) Ltd. April 17, 1964 [April 17, 1963], No. 15135/63. Heading B2P. [Also in Divisions B3 and B8] A machine for cleaning eggs &c. has a cleaning chamber 1 through which eggs are conveyed by a helical conveyer 9 driven by an electric motor 18. The lower part of the chamber 1 is formed to provide a grit hopper 21 having a removable closure 22 normally held in place by springs 23. The motor 18 drives, through belt 19, a centrifugal fan 20 delivering air through a passage 25 to a manifold 24 having a row of air blast nozzle devices each comprising a primary air nozzle 26 delivering air from the manifold to a secondary nozzle 27 also supplied with grit-laden air through a passage 29. Converging baffles 30, 31 have their lower ends just above the conveyer. A manifold 34 supplied through passage 35 from the manifold 24 has air nozzles 33 in the lower part of the hopper which supply grit-laden air to the passages 29. The inlet of the fan 20 is connected by passage 36 to the interior of a tubular coarse mesh filter 37 supported within the chamber 1 adjacent the longitudinal axis of the chamber. The blast is directed on the eggs in a direction having a substantial component tangential to circles having the longitudinal axis of the chamber for centre. The grit tends by its momentum to become separated from the air and fall into the hopper 21; also the air tends to rotate about the longitudinal axis of the chamber so that grit still thereon tends to move into the outer circumferential portions of the air by centrifugal force and then drop into the hopper, air flowing into the fan being substantially free from grit. Communicating with and extending slightly into the outer circumferential wall of the fan casing at an angle such that air tends to enter it, is a small air escape passage 38 communicating with a cyclone dust separator 39 having an outlet 40 provided with a fine mesh dust filter 41.

Title: Improvements in or relating to the screening of amplifying valves
IPC: H01J5/08
Filed: 1942-10-29
Abstract: 567,971. Thermionic valves. LIEBMANN, G.,'and CATHODEON, Ltd. Oct. 29, 1942, No. 15190. [Class 39 (i)] To improve the heat dissipation from an amplifying valve surrounded by a screening can, a layer of material combining high thermal conductivity with high absorption coefficient for thermal radiation is interposed between the can and the yalve envelope so as to be in intimate thermal contact with both. Thus, heat transfer between the envelope and the can is improved while at the same time heat reflected back from the can is absorbed. Suitable materials are graphite or finelydivided metals such as platimun black, but lamp-black is not suitable. The space between the can and the envelope can be filled with graphite powder, or the envelope can be covered with a paste of graphite in a setting binder before the can is pushed over it. The can may be provided with cooling fins. In a modification, the can is replaced by a metallic coating on the envelope which is sprayed on over a layer of graphite.

Abstract: 633,509. Optical gauging-apparatus. BRITISH CELLOPHANE, Ltd., and SAMWAYS, B. June 13, 1947, No. 15692. [Class 106 (ii)] Transparent birefringent film of artificial organic material travelling in a substantially fixed path is passed through an optical gauging- apparatus, utilizing polarized light, the variation in the film width being recorded on a chemically photo-sensitive sheet or film. As shown, the side edges of the film 1 pass between two optical systems consisting of constant light sources 8, 8<SP>1</SP> projecting light through narrow slits covered by ground glass covers 2, 2<SP>1</SP> over which are light-polarizing sheets 3, 3<SP>1</SP> for converting the light to plane polarized light. A second set of light-polarizing sheets 4, 41 is arranged to receive the plane polarized light and set for extinction therewith, and pairs of plane glass or metal mirrors 5, 5<SP>1</SP> are adapted to reflect any light transmitted by the means 4, 41 to form by reflection a virtual image 10 combining images 9, 9<SP>1</SP> of the edge portions of the film 1. The properties of the film 1 are such that light passing therethrough will be transmitted by the second means 4, 41. A photographic camera 6 is focused so as to record on chemically photo-sensitive film 7 a photograph of the combined image 10. The film 7 is continuous and drawn forward either at a constant speed, or at a speed bearing a constant relation to that of the machine for casting the transparent film 1. Scales inscribed in the slits of the light sources 8, 81 are also photographed. In a modification, above each side edge of the transparent film 1 is arranged a system comprising a light source, a collimating lens, and a light-polarizing sheet, but the right-hand system covers more of the film edge than the left-hand system. Further light-polarizing sheets are arranged below the film and set for extinction with the first sheets, and plane mirrors, which are staggered vertically, are positioned to reflect any light transmitted by the second sheets either on to a moving photo-sensitive web of paper or on to a slit in an opaque screen which is continuously photographed. The reflections from the two mirrors are adjusted so that when projected they lie end to end on the paper web or screen.
