Title: Method of printing and printer for employing the method
IPC: G06K15/06
Filed: 1966-04-13
Abstract: 1,093,747. Photographic type-composing. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 13, 1966 [May 18, 1965], No. 16103/66. Heading B6W. Lines of characters are printed on a photosensitive record medium 10 which moves continuously in line-spacing direction, the characters being printed in succession along a track which is at an angle to the line length. Two pulsed-arc lamps 1 are mounted diametrically oppositely on the inner part of a rotor 34 in association with lenses 3, further lenses 9 being mounted in radial alignment therewith on an outer part of the rotor. The medium 10 moves in a direction at an angle to the axis of the rotor, and is wrapped partially round the outer part of the rotor, so that the optical path associated with each lamp traverses each character position on the medium 10 in succession, and each lamp being used for alternate lines. A second rotor 7, which is rotated rapidly in comparison with the rotor 34 and in the opposite direction, carries a set of circumferentially spaced character masks 5, the set together making up a complete font of characters. The speeds are such that every mask passes across the optical path when the latter is in each character position, and when a selected mask is passing across the path, the lamp is activated to emit a short light pulse. Each mask is associated with a prism which corrects for the variation in the exact position of the optical path when the mask crosses it, according to which mask is selected. The rotor 7 is formed with a flange having above each character mask a coded arrangement of perforations 46, through which light from lamps 49 passes to optical sensors 44 moving with the rotor 34, thus transmitting signals to a selector device, which, according to said signals and character-selecting signals. activates the lamps through conductive rings 48, at the requisite instants.

Filed: 1960-05-06
Abstract: 946,567. Agglutinated fibrous fabrics. FRANCAISE DU FERODO.S.A. May 6,1960 [May 6, 1959], No. 16179/60. Heading D1R. A protective band-like porous covering material, intended to be applied over a pipe or other surface coated with a base of heavy hydrocarbon material such as petroleum bitumen, coal pitch, asphalt, tar, or mixtures thereof e.g. by helical wrapping, is formed of asbestos felt paper or fabric,with or without wire or glass fabric or cloth reinforcement, and is impregnated with a heavy hydrocarbon as above defined of which the density decreases progressively from the outer face of the material to the inner and which incorporates a protective material such as talc, kaolin or carbon powder, which is concentrated at the outer face. The impregnated material is prepared by causing a substantially homogeneous or homogenised mixture to stream from a tank 15 through nozzles 16 over one face only of a web 10, e.g. of asbestos felt, while moving obliquely, the impregnant being consolidated by a roller 18 and the impregnated web being dried in an oven 19 and wound up at 20. The impregnating apparatus may be combined with a felting machine and the felted web so produced may be impregnated during manufacture with part of the impregnating medium. The impregnant used contains plastifying agents and/or adjuvants and a suitable solvent such as thrichlorethylene. The face of the felt which receives the impregnating mixture becomes coated with loading agents and other insoluble products, while the other constituents, especially those miscible with the coating material, tend to pass through towards the other face. Plasticizers and adjuvants referred to include butyl phthalate, sodium benzoate, hexachlorbenzene, coumaroneindene and other resins, linseed and other siccative oils, and rubber or synthetic rubber. The loading agents used may include aluminium powder which remains on the surface of the covering and, when the latter is used for wrapping pipes, provides protection for the pipes against solar radiation.

Title: Film handling apparatus with reception chamber for sound and  silent film
IPC: G03B1/50
Filed: 1974-04-11
Abstract: 1467342 Cine cameras K VOCKENHUBER and R HAUSER 11 April 1974 [16 April 1973 24 May 1973] 16255/74 Heading G2E A cine camera having means for sensing whether or not a sound film cartridge has been inserted therein has pressure means for pressing the film against a drive capstan, the pressure means and the capstan being movable apart so that the film may be inserted between them. As seen in Fig. 2, the cartridge-receiving space 4 in the camera has on its underside a movable plate 25, which remains in the same position when a silent film cartridge is inserted. When the larger sound film cartridge is inserted, plate 25 is pushed downwards, so causing levers 31 and 42 to pivot clockwise and anticlockwise respectively. As lever 31 pivots, it pushes a slide 32 upwards, which aligns an aperture 41 therein with an aperture 36, so that a microphone plug can be inserted into the socket 35. The slide also carries indicia (38, 39), Fig. 3 (not shown) for showing whether the arrangement is set for silent or sound film operation. Two tracers (47), Fig. 1 (not shown) are also provided for detecting the presence of a sound film cartridge. Each tracer 47 extends through an opening 51 in the cartridge wall 48, and a lever 49 is urged by a spring 50 against the rear of the tracer. Lever 49 is disposed on a spindle 53 which also carries a lug 54 which extends through an eye in a further lever 57. Lever 57, which is pivoted on an axis 58, carries a pinch roller 56, and the lever is urged by a spring 59 so as to bring the roller 56 into contact with a sound head capstan 55, but capstan and roller are kept out of contact because spring 50 is stronger than spring 59. However, when a sound cartridge is inserted into the camera, levers 49 and 54 are pivoted in such a way that spring 49 is able to draw pinch roller 56 into contact with capstan 55. Other methods of bringing the pinch roller into contact with the capstan on insertion of the cartridge are described and illustrated.

Patent GB-691504-A (GB)
Title: Process of chlorinating saturated or unsaturated hydrocarbons or their derivatives
IPC: C07C17/12
Filed: 1951-07-10
Abstract: Hydrocarbons or their derivatives are chlorinated by means of gaseous chlorine, the chlorination being carried out in an aqueous emulsion. The process can be used for the substitution of hydrogen by chlorine or for the addition of chlorine at carbon-to-carbon double bonds. Hydrocarbons which contain chlorine or other substituents, for example a hydroxyl, carboxyl, carbonyl or nitro group, may be chlorinated by this process. Chlorination of substituted aromatic hydrocarbons results principally in chlorination in the o-position. For the preparation of the emulsions, emulsifiers are preferably employed which are capable of emulsifying the hydrocarbons to be chlorinated in water without being affected by the chlorine. Suitable emulsifiers are the sulphonates of long-chain paraffin hydrocarbons produced by the Fischer-Tropsch synthesis, hydroxy-octodecanesulphonates and arylalkylsulphonates such as diisobutylnaphthalene sulphonate and the like.  The chlorination may be carried out under superatmospheric pressure, continuously or batchwise, or in the presence of chlorination catalysts or with the aid of light.  When alkyl-substituted aromatic hydrocarbons are chlorinated at elevated temperatures under the influence of light the sidechain is chlorinated; at lower temperatures, however, the aromatic nucleus is principally chlorinated.  By carrying out the chlorination first at atmospheric temperature and subsequently at a higher temperature under the influence of light, it is possible to introduce chlorine atoms into the nucleus and the sidechain.  In the examples: (a) vinyl chloride in aqueous emulsion is chlorinated to give trichloroethane; (b) a mixture of 1,2-dichloropropane and dichlorodipropyl ether are obtained by chlorinating propylene in aqueous emulsion; (c) monochlorobenzene with some o- and p-dichlorobenzene is obtained by chlorinating benzene in aqueous solution; and (d) toluene is chlorinated in aqueous emulsion to give monochlortoluene.  German Specification 715,747 is referred to.
