Title: Improvements in film-transmitting television apparatus
IPC: H04N3/38
Filed: 1943-10-27
Abstract: 626,205. Television transmitters. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. Oct. 27, 1943, No. 17739. [Class 40 (iii)] In television transmitting apparatus adapted to transmit cinema film of the kind in which the height of the opaque portion between pictures is comparable with the height of a picture, the apertures in the scanning disc are arranged in a plurality of groups to provide an interlacing scan of a film picture frame and each group is so relatively arranged that not any or only part of the opaque portion between film picture frames is scanned during transmission. The invention is realized in practice by scanning a moving film with a disc in which the apertures are arranged substantially on a spiral which has a discontinuity at which its radius changes abruptly the pitch of the two portions of the spiral remaining unchanged and such that the radial component of motion of the scanning apertures is in the opposite direction but at the same speed as the linear motion of the film. With this arrangement the total area scanned is that of the picture, together with a narrow opaque border (i.e. el to d<1> and e<2> to d<2>), the width of the border being just sufficient to allow for the transmission of synchronizing signals. Specification 482,049 is referred to.

Title: Ingot casting handling apparatus
IPC: B22D5/00
Filed: 1969-04-08
Abstract: 1,221,749. Foundry plant. NIPPON LIGHT METAL CO. Ltd. 8 April, 1969 [8 April, 1968], No. 17802/69. Heading B3F. [Also in Division B8] A handling apparatus for cast ingots includes a roller base 5 reciprocable by means of an arm 73 attached to a piston-rod 72, a stop member 55 for preventing rearward movement of ingots A on rearward movement of the roller base 5, and a turntable 6 which is movable in a vertical direction by means of chains 83 and isrotatable through 90 degrees by means 62. A given number of ingots are received from a conveyer 4 (Fig. 1) on to a roller base 3 which then pivots about the point 31 until it is horizontal. They are thus transferred to the reciprocal roller base 5 which is moved first to the right in Fig. 2 and then to the left by means of the arm 73 so that a batch of ingots already on the roller base 5 is moved on to the turntable 6 (Fig. 4F). This is then lowered a distance equal to the height of the ingots and rotated through 90 degrees ready to receive the next batch. When the turntable 6 reaches its lowermost position, the ingots are pushed off the turntable by means of a cylinder 107. Control of the sequence of operations is by limit switches b-i, m and n and movement of the turntable 6 is controlled by means of a light projector k and detector l. The presence of ingots on the turntable interrupts the beam of light and causes the turntable to be lowered until the ingots move out of the beam. In Figs. 5 and 6 (not shown), the ingots are transferred from the roller base 3 to the reciproeating roller base 5 by means of a table (120) which may be rotated through 90 degrees and may be elevated and lowered.

Title: Improvements in, and relating to, the manufacture and production of artificial threads, filaments and the like
IPC: D01F2/30
Filed: 1926-07-19
Abstract: 278,814. Courtaulds, Ltd., and Lewis, F. D. July 19, 1926. Apparatus for making filaments; cellulose acetates, processes for making filaments from.- When dry-spinning cellulose acetate &c. artificial threads &c., the solution at the spinning nozzle the air in the neighbourhood of the nozzle are maintained at the same temperature by subjecting both the solution and the air to the same heat. Thus, the spinning solution may be passed through a pipe which traverses the length of the spinning chamber, or it may be led through a coiled or spiral pipe adjacent to the spinning nozzle, or the solution-supply pipe may pass through the hot water jacket of the chamber or through a vessel into which the hot water from the jacket, flows. By equalising the temperature of the solution and the air in this way it is possible to control the lustre of the filaments, and also their cross-section so as to produce at will scintillating or non-scintillating threads. Threads of the highest lustre and free from glitter are obtained by employing a common temperature approaching the highest temperature compatible with continuous spinning; lowering the temperature decreases the lustre and later leads to the production of threads showing the effect of glitter. The maximum common temperature depends on the other factors; if the concentration of the spinning solution is increased or a solvent of lower boiling point is employed, the temperature has to be lowered; on the other hand, if the air leaving the chamber contains a higher proportion of solvent vapours, the temperature has to be increased.

Title: Improvements in or relating to gas turbine engine installations driving propellers
Inventor: RODGERS HARRY FREDERICK
IPC: F02C7/32
Filed: 1955-06-22
Abstract: 792,058. Gas turbine plant. BRISTOL AERO-ENGINES, Ltd. June 18, 1956 [June 22, 1955], No. 18111/55. Class 110 (3). [Also in Group XXXIV] A gas turbine engine comprising two independent rotary systems including a turbine, one of which turbines drives a compressor and the other of which drives a propeller through reduction gearing and may, in addition, drive a further compressor directly, has the main oil pump driven from both of the rotary systems through a differential mechanism so that the oil pump is driven at a speed which is a function of the sum of the rotational speeds of the two independent rotary systems. The invention is described with reference to two gas turbine engines in one of which the second turbine drives the propeller only and in the other of which the second turbine drives directly a second compressor as well as the propeller. In the first arrangement the differential gear is arranged in a casing located between the compressor and the propeller reduction gear. In the second arrangement the differential gear casing is arranged between the two compressors. The shaft 16, Fig. 2, connecting the turbine to the propeller reduction gear has a sleeve 23, formed with gear teeth 25, mounted on it. The teeth 25 mesh with a gear-wheel 28 having a hollow shaft 29 journalled in a boss 26 forming part of the differential gear casing. A bevel gearwheel 33, bolted to the gear-wheel 28, meshes with two planetary bevel wheels 34, 35 carried by a spider member 38. The member 38 has a hollow shaft 42 which passes through the hollow shaft 29 and carries a bevel wheel 44 which meshes with a bevel gear-wheel 55 connected by the shaft 56 to the main oil pump. The planetary bevel wheels 34, 35 also engage a bevel wheel 46 carried by a gear-wheel 48 driven by gear teeth 53 formed on a.flange which extends from the compressor forming part of a second rotary system. The gear-wheel 48 is supported on a shaft 49 which passes through the shaft 42. The shafts 29, 42, 49 are freely rotatable with respect to one another. The differential gear arrangement is such that the speed of the bevel gear-wheel 44 is half the sum of the rotational speeds of the gear-wheels 28, 48.

Abstract: Reinforced articles comprise glass in combination in weight ratios of from 1 : 4 to 7 : 3 with a solid stage condensation product of an organic salt of a diprimary amine with a diester formed by the reaction of pyromellitic anhydride with a volatile monohydric alcohol, the condensation product having an inherent viscosity of from 0.04 to 0.4 and being capable of conversion by heat into high molecular weight material of low to moderate crystallinity having a glassy state transition temperature of at least 100 DEG  C. Specified diamines are 4,4-dimethylheptamethylene, nonamethylene, 3-methylheptamethylene, heptamethylene, octamethylene and decamethylene diamine, a mixture of hexamethylene and nonamethylene diamine and a mixture of nonamethylene, hexamethylene or 4,4-dimethylheptamethylene diamine with di-(p-aminocyclohexyl) methane.  Specified alcohols are methyl, ethyl and propyl alcohol. The glass may be in the form of powders, fibres, filaments, yarns, chopped fibre mats, woven fabrics and solid plates.  The articles are made by combining the glass with a solution of the organic salt, evaporating the solvent to deposit the salt and partially condensing the salt to form a porous mass which may be converted to a nonporous state by heating under a slight pressure.  The organic salt solution may also contain heat stabilizers, viscosity stabilizers, colour stabilizers, pigments, dyes, metal fillers, siliceous materials, synthetic polymers, e.g. polytetrafluoroethylene, finely-divided carbon of colloidal size and blowing agents to produce a foamed product.  In the examples: (1) pyromellitic anhydride is dissolved in ethanol, 4,4-dimethylheptamethylene diamine added to the resultant diethyl pyromellitic acid and the resultant isolated organic salt dissolved in water and used to impregnate glass cloths which are dried, heated and then heated again under pressure to form a six-ply laminate; (6) the aqueous organic salt solution of Example 1 is slurried with glass fibres, the resultant mixture being dried and heated to yield a porous mat which is then heated and pressed. The remaining examples describe the preparation of laminates from fibrous or plate glass, using the resin of Example 1 or similar resins prepared from nonamethylene diamine.  Uses.-The articles of the invention may be used as building construction materials, cartons, machine parts, electrical parts and insulation, bearings, slides, hot water pipes, serving trays or in vehicles.
