Abstract: 943,079. Printed circuits. NATIONAL CASH REGISTER CO. Oct. 16, 1962 [Nov. 13, 1961], No. 39120/62. Heading H1R. A printed circuit in which the conductors are flush with the surface of the dielectric panel in which they are embedded is made by adhering a sheet of conductive material to a temporary support, forming the conductive pattern from the sheet, casting uncured dielectric material around the exposed surfaces of the conductors, curing the dielectric material, and removing the temporary support. As shown, Fig. 1, a copper sheet 10 is held by suction against a perforated backing plate 11 while a mould 21 is placed on the sheet 10 and filled with casting wax 22, e.g. paraffin wax. When the wax has hardened to form a temporary support, a circuit pattern is formed from the copper sheet 10, as by acid etching; then a second mould 23, Fig. 4, is fitted over mould 21 and filled with a casting resin, 24, e.g. epoxy resin, which is then cured. The mould 23 is removed and the wax 22 is melted away.

[Class 34 (ii).] Knitted goods such as hosiery are dried on open frames which are moved through the drying chamber on an endless chain conveyer, the articles being held in tension by the weight of a member sliding in each frame and to which each article is secured. A weight 3 slides in the lower members of a frame or form 1 on to which a stocking, for example, is fitted. The open end of the stocking is clamped round the weight by perforated gripper plates 5 supported on jaws 4 held apart, when the weight is raised, by a spring 11. A lever 8 having fingers 9, 10 closes the jaws against the weight 3. These forms are mounted on an endless chain 24, and passed first through a section 27 in which they are treated with steam, or ammonia, or other vapour, from a perforated pipe 31, after which they enter a drying section 28 supplied by a fan 32 with air heated by coils 33. The articles are then conditioned in section 29, and the former pass out and into proximity with a stop 40 and cam surface 37 which raises the weights 3 and releases the jaws 4, so that fresh articles may be fitted.

Title: Apparatus for automatically processing and selecting asbestos fibres
IPC: D02G3/20
Filed: 1963-10-07
Abstract: Apparatus for processing asbestos comprises a casing containing a rotary shaft in its lower part carrying radial rods for feeding the asbestos, an outlet at the top for withdrawing light fibres by means of a fan to a silo, and an outlet at the bottom from which heavy fibres are passed to an opener and recycled.  In Figs. 1 and 2 (not shown), crysotile and amphibole asbestos fibres respectively are fed from hoppers (7, 8) to screw conveyers (1, 2), through gravel discharges (9, 10) and into casing (13), amphibole fibres being additionally treated in opener (14).  Light fibres are withdrawn through conduit (16) by means of fan (17) and are conveyed through delivery adjusting valve (19) to collecting silos. Heavy fibres fall through stationary rods (24), are beaten by rotating rods (22), and pass through outlet (25), screw conveyer (26), gravel discharge (29), opener (30), and conduit (32) to the top of the apparatus.  The speed of the screw conveyers 1, 2 and 26 and of fan 17 can be varied as required. Hoppers 7 and 8 are controlled by a photoelectric cell, which stops the apparatus on failure of fibre supply.ALSO:Apparatus for processing asbestos comprises a casing containing a rotary shaft in its lower part carrying radial rods for beating heavy fibres, inlets at the top for feeding the asbestos, an outlet at the top for withdrawing light fibres by means of a fan to a silo, and an outlet at the bottom from which heavy fibres are passed to an opener and recycled.

Abstract: 1,175,945. Determining person's line of sight. HONEYWELL Inc. 19 Aug., 1968 [23 Aug., 1967], No. 39539/68. Heading H4D. Specification describes an optical system for determining the orientation of a person's eyeball and thus his line of sight, and may be used by a fighter pilot to direct weapons &c. towards a target merely by looking at said target. A beam splitter 14, e.g. a semi-silvered mirror, directs light from source 12 on to eye 10. Part of the light is reflected by the front of lens 18 and part passes into the eyeball to be reflected by retina 16 and re-exit out of lens 18. The portions of reflected light pass via beam splitter 14, lens 20 and stop 26 and an image sensor 22. The light reflected by the retina 16 forms a circular patch of light at 22 (image of lens 18) and the light reflected by the part of lens 18 forms a point of light. The orientation of the eyeball is given by the relative positions of the centres of the patch and point of light. The determined relative position can be fed to servo/computer system 24 for weapon control &c. The image sensor may comprise a T.V. camera using a form of radial scan. If the head of the pilot &c. is fixed the orientation of the eye is determined from the position of the patch of light.

Title: Storage-stable sweet corn powder and the production thereof
IPC: A23L23/10
Filed: 1959-11-24
Abstract: In a powder particularly suitable for making soups, having a basis of sweet corn and of composition 2-5% water, 5-15% protein, 10-55% fat, 1-3% ash and 30-70% carbohydrate, the particle size is 20-60 micron and the fat of the powder is encapsulated by a film of protein and amylaceous substances. Production of the powder involves grinding sweet corn, e.g. sweet corn seeds harvested 18 days after flowering of the maize or canned sweet corn, filtering off husks and other incompletely ground material from the cream so produced, mixing with edible fat or fatty oil such as hardened cottonseed oil, butter fat containing antioxidants and lecithin, beef or pork fat, with stirring and homogenization, to form an oil-in-water type emulsion in which the fat particles are preferably of size less than 30 micron, and drying, preferably spray-drying, the emulsion to a powder.  Corn soup powders may be prepared by mixing the powder with corn starch, whole or skimmed milk powder and the flavouring materials and spices commonly used in soup making or, alternatively, by incorporating some or all of these soup ingredients, other than the corn starch, in the sweet corn-fat emulsion, drying the emulsion, and then incorporating the corn starch and any remaining ingredients.  Examples of preparing the corn soup powders are (i) mixing the sweet corn powder with corn starch, dried skimmed milk, sodium glutamate, dried onion powder, pepper, sugar and salt; (ii) heating corn starch and wheat flour with hardened cottonseed oil, incorporating sugar, sodium glutamate, pepper and salt, cooling, pulverizing, and mixing the powder so obtained with a powder obtained by spray-drying a water emulsion of sweet corn, dried skim milk, dried onion powder, sucrose monostearate and hardened cottonseed oil.  In making the powder, fat-soluble vitamins may be added to the fat preliminarily and water-soluble vitamins may be dissolved in the sweet corn-fat emulsion.  The powder may be mixed with wheat flour for making fritters, cakes and bread.
