Title: Apparatus for correcting and reproducing aerial photographs
IPC: G01C11/04
Filed: 1919-10-31
Abstract: 160,869. Roussilhe, H. Oct. 31, 1919. Photographic surveying-instruments. - Projection copying-apparatus for use in producing corrected reproductions from aerial photographs about which the only data known are the centre of the picture and the focal length of the camera lens, comprises in combination a negative holder P, lens holder B, and image plane e, mutually adjustable on a graduated baseboard T, each element being angularly adjustable about a horizontal axis perpendicular to the projection axis and provided with scales S<2>, V, S<3> respectively to indicate the inclinations a, Á, and a<1>. The negative holder is also mounted in a circular frame g, Figs. 2 and 3, sea as to be rotatable, as by cords c, in its own plane and is provided with a centre hair line F. The holder is tilted on the horizontal axis b, b by pinions u, S<1> and carries a scale pointer I<1>. The lens is tilted by means of a plate a<1>, Fig. 6, which is positioned between a resilient stop y and an adjustable screw V with a scale head x. In use the negative is positioned in the holder and three reference points (in the simplest case on the same contour line) are correctly plotted on the image plane e. The negative, lens, and image plane are adjusted until the projections of the corresponding points on the negative coincide with the plotted reference points. From a reading of the angles a, a<1>, and the conjugate distances of the negative and image planes from the lens, it is possible by certain formulµ or plotted curves to obtain the altitude of the camera negative, the inclination of the negative to the ground, the horizontal distance from the foot of the perpendicular from the camera to the point on the ground corresponding to the centre of the negative, the angle of decentralization Á which must be given to the lens in subsequently obtaining corrected reproductions. The direction of the line of greatest inclination passing through the centre of the photograph is also given by the image of the hair line F. Specifications 1196/04 and 16812/06 are referred to.

Title: Associative memory logical connectives
Inventor: BEHNKE FLOYD ANTHONY
IPC: G11C15/06
Filed: 1963-07-06
Abstract: 1,011,004. Associative data-stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 3, 1964 [July 6, 1963], No. 26855/63. Heading G4C. In an associative memory having means to select which fields of the stored data words are to be searched, logical connective means selectable to carry out either the AND or the OR function are provided between adjacent fields in each stored word. In Figs. 1a, 1b, the logical connective means are the blocks labelled "AND/OR LOGIC ", corresponding ones of these blocks in all stored words being rendered operative when a ONE is stored in a corresponding bit position of a field selection register comprising bi-stable devices 110 to 113. All operative "AND/OR LOGIC" blocks perform either the AND or the OR function depending on the state of a (single) bi - stable and/or register 109. The fields to be compared with the data in an interrogation register are selected by having ZEROES in corresponding positions of a mask register. Comparison in the non- masked fields is to determine whether or not the stored data is greater than, less than or equal to the interrogation register data, depending on the setting of a range selection register 116. In the example illustrated, only one set of "AND/OR LOGIC" blocks is rendered operative (115 etc.), by a ONE in device 113, and AND and " high " are selected, so the simultaneous associative search determines which stored words have both the bit sequence to the left of block 115 and that to the right greater than the corresponding sequences in the interrogation register, a match indicator being set for such words. If OR had been chosen either sequence being greater would have sufficed to set the indicator. Thus non-operative " AND/OR LOGIC " blocks are as if non-existent and all non-masked bits in a given stored word are treated as parts of the same number for comparison purposes except when an operative " AND/OR LOGIC " block intervenes, each such operative block causing splitting into two numbers. It is mentioned that the memory may be cryogenic and Fig. 3 (not shown) shows cryogenic circuitry of those parts of the system peculiar to the invention.

Title: Improvements in or relating to colour television receivers
Inventor: BEDFORD LESLIE HERBERT
IPC: H04N9/67
Filed: 1950-11-03
Abstract: 718,593. Colour television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 5, 1951 [Nov. 3, 1950], No. 26946/50. Class 40 (3). [Also in Group XXXVI] Relates to a television receiver capable of reproducing monochrome pictures from conventional monochrome signals and capable of reproducing coloured pictures from the signals received from a transmitter of the type disclosed in Specification 698,949 which transmits a monochrome brightness signal w and two subcarriers modulated negatively by red and blue colour index signals Kr and Kb respectively, the index of a colour being the proportion of the total brightness contributed by that colour. To produce coloured pictures, the brightness signal w is applied in parallel to the outer grids of the hexodes V1, V2. V3 which have a common cathode load CR and the separated red and blue subcarriers are applied to diodes D (R) and D (B) respectively producing negative signals of amplitude inversely proportional to the colour indices Kr, Kb which are applied to the inner grids of V2 and V3 respectively, the inner grid of V1 being maintained at a constant potential. Since the total cathode current is substantially constant, the cathode currents of V2, V3 and VI are proportional to Kr, Kb and (1-Kr-Kb)=Kg and the signals at the anodes of V2, V3 and V1 are proportional to w Kr=R, w Kb=B and w Kg=G where R, B and G are the required red, blue and green signals which are applied to the cathodes of three colour reproducing tubes TR, TB and TG. When receiving monochrome signals, the subcarrier inputs are disconnected and the bias sources BS adjusted to produce the requisite brightness distribution.

Title: Plant for the manufacture of halogenated hydrocarbons
IPC: C07C17/02
Filed: 1945-10-15
Abstract: Apparatus for preparing halogenated hydrocarbons from mixtures of halogens with acetylene or other hydrocarbons, which mixtures are explosive in the gaseous state, by reaction of the halogen and hydrocarbon both in solution, comprises a synthesising chamber and two dissolving towers each provided with an injector and each connected at the top and bottom to said chamber, and means being provided to set up a controllable circulation of the solvent between said chamber and towers.  In operation of the apparatus shown in the Figure, part of the reaction product utilized as p  solvent leaving the synthesising chamber A runs into the upper part of the two towers B and C containing a filler of inert material where it dissolves the gases introduced through the <PICT:0604384/IV(b)/1> tubes 1 and 3, the solutions formed pass to the chamber A by the conduits 2 and 4. The flow of solution can be controlled by small propellers 5 and 6 placed in the conduits 2 and 4 and by further valves 7 and 8.  The heat of reaction can be dissipated by dividing the synthesising chamber into a number of elements between which tubular sections D are arranged.  The pressure is maintained constant by an air vent F with a water lock.  The vapours of the halogenated hydrocarbons are condensed at E and return to the synthesiser while residuary gases or the undissolved gases in the towers pass into the condensers G where the entrained solvent is condensed and returns to the tower, whilst residuary gases leave the installation through a water lock.  The finished product is removed at the upper part of the chamber A.  The synthesis of tetrachlorethane by means of the apparatus is mentioned. The Specification as open to inspection under Sect. 91 states that halogenation, e.g. the reaction of chlorine and acetylene, may be effected by employing one solution tower only and introducing one of the gases into the synthesising apparatus which receives the solution coming from the tower in which the other gas has been dissolved. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the manufacture of cinematograph films
IPC: B41M3/00
Filed: 1936-10-07
Abstract: 483,044. Photo - mechanical printing of picture and sound films. ARMSTRONG, J. J. V. Oct. 7, 1936, Nos. 27209 and 29449. [Class 98 (ii)] Kinematograph films bearing pictures with or without sound tracks or sound tracks alone are produced by printing from an original record on transparent material onto a lightsensitive layer on a metallic strip without the use of any photo-mechanical screen or graining and forming depressions on the metallic strip corresponding in area to the silver image on the original and in depth to the tones of the original viewed as a transparency, the images being then inked and used to print onto a receptive surface. Instead of printing directly onto the metallic strip a separate light-sensitive layer, e.g. a bichromated colloid layer may be used and subsequently transferred to the surface of the metallic strip. The receptive surface may be a cellulose acetate strip, the printing ink then containing a solvent for cellulose acetate, e.g. acetone. For variable density sound tracks a semi-transparent ink is used and for variable area tracks an opaque ink. The metallic strip may be of copper and may be coated with a mixture of colloids such as fish glue and gelatin, or a known cold enamel as used for line blocks may be employed. Paper may also be used as the receptive surface. According to the first Provisional Specification, coloured kinematograph films may be produced by successive printings from ribbons of zinc or other metal each bearing sets of spaced parallel lines of resist coated under or over the light-sensitive layer, the records corresponding to one of the colours of a multicolour screen record being printed on the layer on each ribbon and the ribbon etched. One of the ribbons may carry a sound track preferably wholly unscreened. Registration may be effected by placing opposite each picture a dot or pair of dots and employing a photoelectric cell in circuit with electromagnetic means for displacing the film if the dot or dots are out of register with the cell. In a modification, negatives made by interposing ruled screens having spaced parallel lines may be used to print on the sensitized strips. According to the second Provisional Specification the printing may be effected by offset and the receptive surface may be of the material known under the Registered Trade Mark " Cellophane." Specification 422,180 is referred to.

Title: Improvements in the linking of knitted fabric and in transferring bars, and instruments for use therein
IPC: D04B15/02
Filed: 1950-11-09
Abstract: 729,912. Knitting. GREY & CO., Ltd., R., and WIGLEY, A. Nov. 9, 1950, No. 27373/50. Class 74 (2). In order to transfer the edge loops of two pieces of knitted fabric from the needles on to a single row of points, with like surfaces of the pieces face to face, one piece of fabric is subjected to one more transfer operation than the other piece by reason of transfer operations which, in the case of at least one of the pieces of fabric, involve transfer operations between successively employed rows of ends of looptransferring instruments. A set of transfer points 4 or 5 is clamped in tricks in a bed 1, by a cap 6 rockable about the part-spherical heads of screws 7, to clamp the points, or to release them, so that, after the points have taken loops of one of the pieces of fabric from a row of needles, their free ends may be inserted and clamped in a similar body and the points released from the first body, the loops being then transferred to linking points. The cap 6 may be rocked by the thrust of a cam bar 8, ramps 11 on which ride up and down pins 12 as the cam bar is slid along a channel 9 by means of a screw 17 and nut 18 turned by a crank 19. Coil springs between bed and cap assist in the point-releasing movement. The longitudinally grooved transfer points may be pointed at one or both ends, for use with bearded needles, or, Fig. 5, may have eyes 18 at both ends, to fit over the hooks of latch needles; or they may have such an eye at one end and the other end pointed. When the points have longitudinal grooves 22, the cap 6 may have corresponding serrations, to enter the grooves.

Title: Improvements in or relating to signs
IPC: G09F13/14
Filed: 1927-10-17
Abstract: 301,604. Hayes, W. H. Oct. 17, 1927. Signs.-Comprises a doublesided reflector sign having opaque reflectors formed with gaps to constitute the stencils. In the illustrated form the glass mirrors 12 are frosted or roughened on the inner side and gilded on the outer smooth surfaces, the stencils being formed by removing parts of the gilding. In some cases the corresponding parts of the plates 12 may be removed to form holes corresponding to the lettering. Metal end frames, spaced by tie-bars 22, are used to complete the sign casing and also carry the mountings for shielded artificial lights. In operation, light passing through the frosted sheet of glass 11 is reflected and diffused from the inner surface of each mrror and passes through the stencil of the opposite mirror, the frosting of the mirrors preventing the interior of the apparatus from being seen by direct vision through either stencil. Covering sheets 15 of tinted glass may be used to cause a corresponding colouring of the sign, or the stencilled letters may be tinted, for example by a. flashing operation. The metal end frames, which may carry glass panels, are grooved to receive the ends of the top and bottom plates of the casing and also to receive pintles on the metal-framed sign plates and covering sheets, and the upper wall 24 of the top groove is removable. The pintleengaging groove 26 allows either mirror to be swung up about the pivot 29 and then moved slidably under the top member 11, thus leaving an open side of the frame for shop window illumination. The reflectors may be mounted so that the angle between them can be. varied. The metal framings of the reflectors can be formed as guides adapted to receive single letters on separate reflecting plates, thus enabling the advertisements to be changed readily. Specification 292,002 is referred to.
