Title: Improvements in and relating to processes for taking and reproducing motion picturesin colours and apparatus therefor
IPC: G03B33/00
Filed: 1937-03-09
Abstract: 489,517. Colour kinematography. LEAN, C. (Oehninger, S.) March 9, 1937. No. 6940. [Classes 97 (i) and 98 (ii)] Three colour-record diapositives corresponding to the primary colours are produced and each is combined with a record coloured in the primary colour of which the diapositive is a record and made from the negative containing the record of the complementary colour. Thus, the positive from the red record negative is combined with a red monochrome printed from the green record negative (which is stated to contain the record of the blue-green range). Similarly, positives from the blue-violet and green record negatives are combined with a blue monochrome printed from the red record negative and a green monochrome printed from the blue-violet record negative respectively. The gradation curves of the monochromes approximate to a reciprocal exponential curve by the use of a master negative having a strongly drooping gradation curve. The pairs of images may be produced on two-layer stock or by imbibition printing of the coloured image on the layer containing the silver image. The three image pairs may be arranged in a single image space of the film by the use of an anamorphotic system for printing. The system may consist of two small lens systems G.V., Fig. 6, for the green and blue-violet images and a larger lens system R for the red image, all the lens systems being anamorphotic. The resulting film consists of three parallel series of images, the central one r<1> of each set of three images r<1>, g<1>, v<1> being displaced into the next image space. An optical system similar to that in Fig. 6 may be used for projection. A modified form of anamorphotio lens system comprises an objective 1 arranged between cross cylindrical lenses 2, 3 and having a composite prism 4 for producing the three images, arranged between the lenses of the objective 1. Specifications 117,864 and 246,154, [both in Class 97 (i)], are referred to.

Title: Transverse flow type blowers
IPC: F04D17/04
Filed: 1962-02-26
Abstract: 977,285. Transverse-flow blowers. T. HELMBOLD. Feb. 26, 1962 [March 23, 1961], No. 7338/62. Addition to 970,047. Heading F1C. A transverse-flow blower comprises a partition outside the rotor between an inlet and an outlet channel, a covering member within and close to the rotor adjacent the partition, and a body within the rotor formed with a concave surface for guiding a cylindrical standing vortex during operation of the blower, the body being disposed at a distance from the covering member, and one or more passages being provided leading from the concave surface to a region or regions where during operation the pressure is lower than at the concave surface. In the blower shown, a cylindrical vortex is stabilized by a concave guide body 6 having a portion 7 spaced from it to form a slot downstream of which a low-pressure region forms during operation. The outer parts of the vortex pass between the guide body 6 and a covering member 8 disposed near the rotor 1 and within the region of a partition 4 separating the inlet channel 2 from the outlet channel 3. The covering member 8 protects the vortex from destruction by the rotor blades. The guide body 6 and the covering member 8 preferably extend over the whole length of the rotor 1 and parallel to its axis, and may both be made adjustable in position, as by pivoting them individually or together around the rotor axis. Instead of being of elongated form as shown, the bulbous end of the guide body 6, the portion 7 and the covering member 8 may be of nearly circular form. The slot defined by the portion 7 may be replaced by bores formed in the body 6 as described in the parent Specification. Since another low-pressure area forms near the convex surface of the body 6 just behind its leading edge, the slot or bores may lead to that area instead of to the trailing edge.

Abstract: 286,739. Sharples Specialty Co., (Assignees of Sharples, L. P.). March 11, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Strainer separators; discharging.-A centrifugal strainer with a helical conveyer for the solids has a zone of small average diameter where the major portion of liquid is removed, and a zone of large average diameter where the material is subjected to a greater centrifugal force and the remainder of the liquid is removed. Arms upon the hub 32 carry the helical plates 34 arranged just inside the rotary screen 10; the plates and screen are driven at different speeds from the shaft 40. The mixture is supplied to the separating space through the pipe 24, and the first separation occurs in the part 22 which is of conical form and of small average diameter. After losing the greater part of its liquid the material passes through the intermediate portion 25 to the portion 23 of large diameter. Further drying occurs in the part 23 and the solids are collected in the hopper 49; the final discharge is controlled by the rotary valve 50. The liquid is collected by a vessel 44 and passes away through the passage 48. Air or other gas may be supplied through the pipe 52; the gas may be heated or it may act chemically upon the solids. The screen is constructed as shown in Fig. 3; the sheet metal shell 10 has perforations 26, and an inner screen 27 has small perforations 28. The two members 10, 27 are separated by a spacing member 29 made of woven wire which permits liquid to circulate. The pitch of the helical plates 34 diminishes as the diameter of the separator increases so that the layer of solids is of apyroximate constant thickness. To prevent any corrosive action from occurring, the shell and the discharge openings may be lined with protective material.

Title: A process for the production of extremely pure semi-conductor material
IPC: C23C16/06
Filed: 1961-03-01
Abstract: <PICT:0929074/III/1> Extremely pure semi-conductor material is produced by deposition from a mixture of gaseous compounds on to a carrier body of the material which is heated by passing an electric current therethrough, and wherein the carrier body is supported on a pure carbon holder and where further carbon holders are purified by treatment with the reaction gas product of the deposition reaction. In the production of silicon, the carrier and reducing gas, e.g. hydrogen is taken from vessel 1 through valves 2 and 3 and flowmeter 4 to chamber 5 where it is mixed with an evaporated silicon compound, e.g. silicochloroform or silicon tetrachloride, and the mixture injected into reaction vessel 10 (quartz) via jet 7.  Carbon holders 13 support silicon carrier bodies 9, bridged by silicon 12 to allow electrical contact.  The reaction gas product flows out through 16 into vessel 18 containing carbon pieces 19. The vessel is heated to 400 DEG  to 700 DEG C. by electrical means 22. The treatment is preferably carried out for at least 100 hours and may be performed intermittently wherein during the intervals, the heating is switched off and the vessel opened to atmospheric oxygen by removing stopper 23.  During the 100 hours, the production of silicon is performed a plurality of times using a plurality of carrier bodies.  Germanium, indium antimonide and silicon carbide may be produced by a similar method.
