Title: Improvements relating to Missile Guidance Systems
Inventor: MCLAUGHLAN DEREK JOHN
IPC: F41G7/30
Filed: 1966-10-01
Abstract: 1,192,366. Missile guidance. BRITISH AIRCRAFT CORP. Ltd. 24 Nov., 1967 [10 Oct., 1966], No. 29772/66. Heading H4D. The Specification describes an air-to-air missile guidance system wherein the target is viewed by a closed circuit television system and the controller is provided with means whereby a light spot on the television display screen can be positioned on the target image and signals from said means indicating the position of the light spot are used to produce flight control signals for the missile. The light spot positioning means may comprise joy-stick 2 connected to two orthogonally positioned potentiometers yielding two orthogonal component signals V x  and V y . The signal V x  is compared with the line scan voltage in comparator 7 and V y  is compared with the frame scan voltage in comparator 8. Detected equality causes the comparators to produce a pulse which triggers the respective monostable circuit 11 or 12. Simultaneous triggered outputs from circuits 11 and 12 causes a bright-up pulse to be added at 15 to the video signal at 16, so producing the light spot in the correct position. The signals V x  and V y  only represent the position of the target when the light spot is correctly positioned on the target response. The controller is thus provided with a marker switch, Fig. 2 (not shown) which is operated when said correct positioning is observed and gates signals V x  and V y  to a computer. A clock signal is simultaneously gated to the computer, giving an indication of the time that the target is at the indicated position. The positioning of the spot may be aided by feedback signals predicating the future position and derived by integrating rate of change of V x  and V y  signals (Fig. 3, not shown).

Title: Methods and means for producing iron and steel
IPC: C21B13/12
Filed: 1926-11-26
Abstract: 262,127. Gustafsson, E. G. T. Nov. 28, 1925, [Convention date]. Extracting.-In a process for the production of iron and steel in an electric furnace, the ore, fluxes, and reducing agents, which may be prcheated, are fed in a thin layer on to a slag bath in the furnace and reduced by the heat developed in the slag. The ore may be partially or wholly reduced, before it reaches the slag bath, in a rotary or other furnace by means of gases from the electric furnace or any other source, and the reducing agent, which may be carbonaceous material or ferro-manganese, ferro-silicon, &c., may also be preheated. The partially or wholly reduced ore and the reducing agent are fed on to the slag bath in such a way that the reducing agent is fed first on to the slag bath and the ore on the top of the reducing agent, in several alternate layers if desired. The ore and the reducing agent may be fed into the furnace continuously or at short intervals and should preferably be in the form of grains of the size of peas or nuts, and the ore before preheating and roasting may be mixed with a suitable binding material. The greater portion of the gases may be passed through the ore preheating and reducing devices and the rest of the gases through the reducing agent preheater. The electrodes in the reduction furnace may be raised or lowered so that the heat may be concentrated as desired in different layers of the slag. When a quantity of metal suitable for tapping has collected in the furnace, the latter may be tapped or run warm to reduce any remaining ore, to decrease the iron content of the slag and to heat the metal and slag to a temperature suitable for tapping. The preheating of the ore may be carried out in a rotarv furnace the outlet of which is connected to a shaft-furnace wherein the ore is reduced, the latter furnace being in turn connected to the electric furnace provided with feeding devices for controlling the supply of reduced ore and reducing agent.

Patent GB-663500-A (GB)
Title: Method of making shaped articles of an acrylonitrile polymer
IPC: D01F6/18
Filed: 1949-11-23
Abstract: Artificial filaments, fibres, films, tubes, and other articles are obtained by extruding a solution of an acrylonitrile polymer in a dimethyl amide of formic or acetic acid into a coagulating liquid comprising a mixture of water and 35-80 per cent by volume of dimethyl formamide or 20-70 per cent by volume of dimethyl acetamide. The acrylonitrile polymer may be polyacrylonitrile itself or a copolymer or interpolymer of acrylonitrile containing at least 65 per cent, preferably 70-98 per cent, of acrylonitrile in the polymer molecule.  Copolymers of acrylonitrile with vinyl acetate, styrene, vinyl chloride, a vinyl pyridine such as 2-vinyl pyridine, isobutene, dimethyl fumarate, methyl methacrylate, methacrylonitrile, acrylic acid, or acrylic esters, may be used. The filaments which are formed may be stretched between godets, or as they are advanced over a thread-advancing and stretching reel, or as they are passed through a steam chamber.  They may be stretched 100-300 per cent at room temperature or at temperatures up to 100 DEG  C., or they may be stretched to a greater extent at temperatures above 100 DEG  C. Stretching may be effected in two stages.  Final stretching may take place in hot air, dry or wet steam, or a heated inert liquid.  All or a substantial amount of the residual solvent adhering to the filaments may be removed e.g. by washing or heating, prior to a stretching treatment.  The stretched filaments may be cut to form staple fibres and these may be treated with a shrinking agent, e.g. hot water, so as to obtain curled fibres.  Small amounts of water may be added to the coagulating bath during the production of the filaments in order to maintain a constant concentration of the dimethyl formamide or acetamide.  When the coagulating liquid contains 20-45 per cent by volume of dimethyl acetamide, the filaments obtained are opaque and of dull lustre and low density. They contain microscopic bubbles or cells and have low dyeing affinities.  On the other hand, when the coagulating liquid contains 45-70 per cent by volume of dimethyl acetamide, the filaments, after washing, drying, and heat-stretching, are dense and transparent, and have good dyeing affinities.  The spinning solution may contain 5-30 per cent or more of the acrylonitrile polymer, and spinning may take place at 25-60 DEG  C.  Yarns, after stretching, may be twisted and then stabilized by allowing them to shrink freely in boiling water. Examples describe the production and stretching of filaments from solutions of copolymers of acrylonitrile with 2-vinyl pyridine, vinyl acetate, acrylamide, or vinyl a -chloroacetate.

Filed: 1931-10-30
Abstract: 383,733. Skinning fish. ATLANTIC COAST FISHERIES CO., 111, John Street, New York, U.S.A. Oct. 30, 1931, No. 30094. Convention date, Oct. 30, 1930. [Class 28 (ii).] - Fish or other objects of a like wet nature are mechanically treated on a support to which they are frozen. As shown, a metal band 4 is trained over drums 2, 3, the drum 2 being cooled and the drum 3 being warmed, whereby the fish is frozen to the band in the vicinity of the drum 2 and, after being skinned by the reciprocating knife 30, is released therefrom in the vicinity of the drum 3. The drums are driven by a belt 12 trained over pulleys 13, 14 and tensioned by an adjustable jockey 23. The drums are rotatable on stationary hollow shafts 5, 5<1> which are plugged to separate the bores into inlet and outlet passages. The inlet portions of the bores are connected to perforated pipes 9, 91 and the outlet portions to draw-off pipes 11, 11<1>. The drum 2 is partially lugged with felt 15 on a wood backing 16, and the drum 3 may be similarly insulated. The band tension is adjusted by screws 22 and, to prevent sagging under the load of fish, the upper run is supported by a table 17. The sides of the band are guided by side strips 19. The skinning knife 30 is secured by screws 32 to a holder 31, which is angularly adjustable by slots 35 and bolts 34 to the disc 36 to which it is secured. The disc 36 is vertically adjustable to compensate for the wear of the knife-edge, by bolts 38 engaging with the slotted end 39 of the slide 40 which is reciprocated by a crank and connecting-rod. The slide 40 is supported by guides 41, one guide having an extension 46 pivoted at 45 and located by a set-screw 48 and a locking bolt and nut 50, 51. The nut 51, when released, allows the knife assembly to be swung, about the pivot 45, away from the drum for sharpening the knife. In operation, the fillets slide over a shoot 53 on to a discharge conveyer 54, and the band 4 is kept free from frost &c. by a non-freezing liquid dripped from a reservoir 55. Suitable liquids are glycerin, ethylene glycol or solutions thereof, or calcium chloride brine. The liquid is prevented from reaching the working surface of the band by wipers 56.

Title: Tractor linkage
IPC: A01B63/10
Filed: 1973-06-25
Abstract: 1426050 Three point tractor linkage P A SHELTON 21 Nov 1973 [22 Nov 1972 25 June 1973] 53937/72 and 30095/73 Heading A1P A three point tractor linkage comprises lower links 13a, 13b which lie in the same plane and which diverge from a point D at or close to ground level, plus upper links 12a, 12b which converge rearwardly to a point A, the upper links lying in a plane which intersects the plane containing the lower links 13a, 13b, the line of intersection BC which passes through the point D being parallel with the ground surface and transverse to the direction of motion of the tractor. Hydraulic rams (not shown) connected between the rear of the tractor and the lower links serve to raise or lower the linkage. The upper linkage consists of two hydraulic rams interconnected in a manner which permits it to move laterally relative to the tractor, either freely or under power; become rigid to lateral displacement; and vary its length. The details of the upper linkage are disclosed in Specification 1422134. A frame member (not shown) interconnects the rear ends of the links and supports upper and lower hooks which engage the upper and lower hitch pins of an agricultural implement. In one embodiment, the lower hooks, which are mounted adjustably on the frame in order to fit a variety of implements are placed beneath the lower hitch pins. The upper hooks are then screwed down until they engage the upper hitch pins. In another embodiment, the upper hooks, which are spring biased, initially engage the upper hitch pins, after which the hydraulic rams cause the lower hitch pins to engage the lower hooks, engagement being maintained by a locking mechanism. A device for detecting the pressure in the upper link rams acts as a draught control by causing the rams connected to the lower links to raise or lower the linkage until the pressure in the upper link rams has reached a preselected value.

Title: Improvements in and relating to colour photography
IPC: G03C7/46
Filed: 1931-10-30
Abstract: 391,493. Colour photography. WILLIAMS, J. E., Miskin Manor, Pontyclun, Glamorgan. Oct. 30, 1931, No. 30101. [Class 98 (ii).] In the production of coloured photographs by printing from colour-record negatives on to pigmented gelatine sensitized with bichromate carried by the final support, the sensitized gelatine applied to the support is so treated as to present a grained, irregular or reticulated surface. The development and preservation of half tones is thereby assisted and the layer is more effectively secured to the support. To obtain the irregular or reticulated surface, the sensitized gelatine emulsion is applied in the warm, liquid state to a muslin or linencovered lithographic stone, board, or other suitable surface and the damp print is squeezed thereon, cooled by a fan, stone or piece of glass, and stripped. A second or third coating may be similarly applied to obtain a greater depth of colour. A blue print is preferably utilized for the blue image. Thus, for a three-colour process, a blue print obtained from the orange negative is dried and coated with bichromated gelatine containing yellow pigment and is then exposed under the violet negative ; after development and drying, a red, bichromated gelatine emulsion is applied and a print is obtained from the yellow negative. For the yellow pigment, deep chrome with a little vermilion is employed ; and for the red, Alizarin crimson with a little vermilion. To preserve the whites, the blue print is brushed over with hydrochloric acid. As soon as the red image is developed, the print is immersed in a strong chrome alum bath and, after drying, is coated with a suitable varnish or gelatine glaze. In place of the blue print, a paper coated with a blue gelatine film may be employed. The prints may be made from a multi-colour screen plate, starch-grain negative, &c. by using complementary printing light for each print. More than three colours may be employed, e.g. a five-colour print may comprise a blue print with superposed prints in bright green, yellow, red, and mauve.

IPC: F01L13/08
Filed: 1928-10-18
Abstract: 303,786. Daimler-Benz Akt.-Ges. Jan. 'J, 1028, [Convention date]. Starting. - For relieving compression when starting oil engines in which fuel is injected without the use of compressed air, the axially adjustable cam shaft is held in its starting position by a stationary retaining device which releases it after the shaft has turned through a definite angle. As shown, the cam shaft a is movable axially for effecting the change to normal compression in stages. A bush d is rotatable in a sleeve f screwed with a quick thread into the wall of the engine casing and turned by means of a handle g to adjust the sleeve axially. The hollow end of the bush is provided with a cover e, and a projection c on the end of the cam shaft a is adapted to pass through a slot in the cover e in a definite angular position of the cam shaft.. To bring the parts into the starting position shown, the cam shaft is moved axially by means of a pin h sliding in the bush d, and the bush is turned so that a spring b holds the projection c against the face of the cover e; compression is thus relieved and the engine can be turned. When the cam shaft has moved sufficiently, the projection c registers with the slot and the spring b moves the cam shaft into the partial compression position, the end of the shaft bearing against the pin h. To bring the cam shaft into the full compression position, the sleeve f is turned by means of the handle g to move the bush d axially.
