Title: Improvements in and relating to lighting fittings
Inventor: HOLMES JOHN GUYSCLIFFE
IPC: F21V5/00
Filed: 1953-09-04
Abstract: 761,365. Street lamp refractors. HOLOPHANE. Ltd. Dec. 6, 1954 [Sept. 4, 1953], No. 24527/53. Classes 75(2) and 75(4) A transparent lighting fitting such as for directional street lighting, incorporating ribbed light-redirecting conformations on both inner and outer surfaces is made of transparent machinable material such as acrylic resins or polystyrene and has at least some of the ribbed conformations on the internal surface produced by machining so that their shape is not dictated by the need for withdrawing a moulding tool. Preferably the external ribs run longitudinally of the fitting or vertical when in use so that they can be produced by moulding and the internal ribs run in planes perpendicular to the longitudinal axis of the fitting and are produced by a turning operation, e.g. of a circular body afterwards deformed into the required shape or of a body deformed into one of circular section and afterwards allowed to return to its non-circular shape. External ribs may also be produced by machining. The fitting, Fig. 1, has a contour comprising a semicircle 11 about the light source LC running into an upward extension 12 having a slight upward divergence from the vertical and having at the top a flange 13 for mounting the bowl 'fittings. Internally the lowest group 14 of circumferential refracting prisms elevate decreasingly the light away from the nadir as their position increases from the centre, into a beam 17, 18 at about 75 degrees to the vertical. The second group of refracting prisms 15 above the line traced on the fitting through which the ray 18 is undeviated refract the light downwards into beams 19 parallel to beams 17 and the third group of prisms 16, above the zone over which useful refraction can be effected, reflect the light into beams 21 parallel to beams 17 and 19; with such a prism system no mould could be employed in the production. Longitudinal prisms are provided externally on the fittings to redirect the emitted light towards two major axes including an angle of 170 degrees for the fitting to be used on the side of the street and to throw some light on to the house side of the street. In another form, a fitting for street lighting (Figs. 3 and 4, not shown) has an open mouth contracting upwardly about the light source, and has a cylindrical skirt and frusto-conical upper section, circumferential refracting prisms in the skirt bending the light rays downwards at an angle of 75 degrees to the vertical and circumferential reflecting prisms in the contracting portion bending the light rays received thereby into parallelism with the refracted rays. External refracting and reflecting longitudinal prisms direct the rays into two beams including an angle of 170 degrees.

Title: A new or improved method and machine for effecting orientation of fibres
IPC: D01G23/00
Filed: 1952-10-01
Abstract: 748,399. Preparing fibres for spinning. TURNBULL, R. H. Jan. 1, 1954 [Oct. 1, 1952], No. 24630/52. Class 120 (1). [Also in Group XXX] Fibres are oriented by depositing them on one of two conveyer surfaces arranged alongside one another and moving at different speeds and/or in opposite directions, and gradually transferring the fibres to the other surface (called the receiving surface) to travel therewith, whereby the difference in speeds, or direction of travel, tends to draw the fibres into alignment with the direction of movement of the receiving surface. As shown, fibres are deposited from a hopper 16 on to a centre conveyer 11 flanked by two outer conveyers 10, 12 moving in the same direction as, but faster than, conveyer 11. Walls 13, 14 extending slightly above the level of conveyers 10, 12 separate the three conveyers; they may be separate from the conveyers or may be fixed to the sides of conveyers 10, 12. Conveyer 11 is moved by cams 20 bodily up and down from a level below conveyers 10, 12 to a level slightly above so that fibres 22 gradually fall from conveyer 11 on to conveyers 10, 12, being thereby drawn into alignment with the direction of movement of the conveyers. Ploughs or scrapers may be provided to guide the fibres to the edges of conveyer 11. In alternative embodiments (a) the upper run of conveyer 11 is supported by small rollers which are moved up and down by cams ; (b) the upper run of conveyer 11 is constrained by rollers to an undulating path in which it alternately rises above and falls below the level of conveyers 10, 12; and (c) conveyer 11 slopes relatively to conveyers 10, 12, starting below the latter conveyers and ending at the same level or above. Specification 721,878 is referred to.

Title: Expanded food products
IPC: A23L1/00
Filed: 1939-08-28
Abstract: 541,004. Food preparations. MUSHER, A. Aug. 28, 1939, No. 24726. Convention date, Sept. 13, 1938. [Class 49] A process for rendering vegetables, fruits, meat and fish of high water and low starch content more readily or quickly cooked, comprises first drying the food material to a low moisture content, and then exploding or expanding it, e.g. by subjecting it to a high temperature and pressure in a closed chamber and then suddenly releasing to atmospheric pressure and temperature, whereby pieces of the material are expanded, without disintegration, into a highly porous and absorbent form enabling them to be cooked by a short immersion in hot or boiling water. The pressure may be created by moisture normally present or by the introduction of steam, superheated steam or water, or fruit, meat or vegetable juices into the pressure chamber. The original moisture content is preferably reduced to below 15 per cent., and the food pieces are subjected in the closed chamber to a pressure of from 20 to 450 pounds per square inch, at a temperature of from 200‹F. to 800‹F. for from 15 seconds to 12 minutes. Before heating, nitrogen or compressed air may be forced into the chamber. The food pieces may be given a preliminary cooking or steaming, or may be frozen before being dried and exploded, and the exploding may be repeated several times. The expanded food material may be coated, impregnated, or sterilised with flavouring material, sugar, oil, fat, &c., and may, with or without the inclusion of binding materials &c. be made into bricts, cakes &c. which readily disintegrate when placed in hot or boiling water. The material may be softened by treatment with enzymes salt solutions, acids, or alkalies.

Title: An improved process for utilising oil seed cakes
IPC: A23K10/37
Filed: 1930-08-19
Abstract: Dried oil seed cakes are ground finely and sieved the meal thus obtained being used with or without other feeding means as a fodder. The starchy material in the residues is saccharified by the action of enzymes or by heating in autoclaves with weak acids the sugar substances being extracted by diffusion.  The cellulose residues from the diffusion process are heated with strong mineral acids (sulphuric acid, sulphurous acid, hydrochloric acid) at raised pressure and converted into alcohol by fermentation.  The sugar solutions obtained from the disintegration of the starchy and the cellulosic materials may be united, neutralized by the addition of lime and the precipitate allowed to settle.  The clear solution is then fermented after addition of yeast that has been grown in a malt extract and then acclimatized by gradual addition of the sugar solutions.  The mash is distilled giving a mixture consisting mainly of ethyl alcohol with methyl alcohol, acetone, and aldehyde.  The process may be applied to cotton seed cake, olive seed cake and the like.ALSO:Dried oil seed cakes are ground finely and sieved the meal thus obtained being used with or without other feeding means as a fodder.

Filed: 1952-10-06
Abstract: 705,896. Purifying gases. AKTIEBOLAGET ROSENBLADS PATENTER. Oct. 6, 1952 [Oct. 6, 1951], No. 24966/52. Class 55 (2) Gas containing naphthalene, e.g. crude coal gas, is cooled by passing it through water showers and the naphthalene is removed by spraying a solvent, e.g. tar, across the flowpath of the cooled gas, fresh solvent being supplied to a circulating quantity of the solvent and some of the circulating quantity being supplied to the cooling- water. The amount of solvent circulating is considerably larger than the amount of the fresh solvent added, and is preferably approximately the same as that of the cooling-water. The process is carried out in a tower 1 to which the gas is passed through an inlet 2 and exhausted through an outlet 3. Cooling-water is supplied through a pipe 15 and is scattered by means of plates 8, 9, &c. on a shaft 4, the scattered liquid collecting in annular troughs 12, 13 and being fed to the next lower scattering-plate. The solvent is supplied through a pipe 18 controlled by a valve 17 and is scattered by a plate 7 on the shaft 4, and collects in a trough 11 whence it is returned by a pump 20, the amount recirculated being controlled by a valve 22, and the excess overflowing at 23 into the water cooling system. The pump 20 can be replaced by a self-lifting rotary spray.

Title: Obtaining a high unidirectional voltage from a electronic oscillation generator
IPC: H04N3/18
Filed: 1947-09-13
Abstract: 644,037. Converting. MURPHY RADIO, Ltd., and KIDD, P. C. Sept. 13, 1947, No. 25138. [Class 38 (ii)] A circuit for obtaining the anode voltage for a cathode-ray tube from a saw-tooth voltage generator, having its anode transformer coupled to a grid, comprises a condenser connected to the anode and grid with a rectifier included in one connection so that the voltages arising on the anode and grid during the flyback period are added and applied to the condenser. A tetrode valve 1 has a primary winding 2 of a scanning transformer in its anode circuit, a secondary winding 3 supplying the scanning coils while another secondary winding 4 applies a voltage to the screen grid, the winding being taken to earth through an adjustable resistor 5 by which the frequency of oscillation may be varied which oscillations may be suitably synchronized by impulses fed on to the control grid of the valve 1. During the flyback period high voltage peaks are generated in the windings 2, 4 which are series connected through .the H.T. source so that the sum of their voltages is applied to a condenser 8 through a rectifier 9, the condenser voltage being fed, by way of a smoothing circuit 12, 13 to the anode of a cathode-ray tube. A further winding 10 may be provided if the voltage for the tube is insufficient. The junction of the transformer windings 2, 4 and not a condenser terminal is earthy and thus minimum effective capacitance is obtained, hence minimum slowing down of the flyback occurs. The elements 12, 13 exert damping effects similar to those of elements 6, 7 which may accordingly be reduced in value or possibly omitted depending upon the size of the elements 12, 13. If the saw-tooth voltage generator supplies the scanning circuit through an amplifier the invention may be applied to the amplifier output transformer (Fig. 2, not shown). The Provisional Specification refers to Specification 643,993.
