Title: Means for the visual indication of information selected from a data storage
IPC: G06F3/02
Filed: 1950-06-23
Abstract: 786,043. Electric digital-data-storage apparatus. DIRKS, G. June 23, 1950 [Oct. 1, 1948], No. 37225/54. Divided out of 786,021. Class 106 (1). [Also in Group XXXVIII] Electrical means for the visual indication of information comprises a storage device for erasible signals, means for the cyclic sensing of the stored signals, and at least one cyclicallyoperable or repetitive indicating device working in tele-synchronism with the sensing means and in dependence on the signals sensed. In a first embodiment, synchronized motors 1 and 2 drive stroboscopic discs 3 and 4 of the type described in Specification 786,026, the flashing of high-intensity lamps 7 and 8 being controlled through an amplifier 14 and discharge tubes 9 and 10 from central selective magnetic drum store 11 to indicate selected numbers or characters at apertures 5 and 6. For the selection of data, or entry of new matter, corrections, &c., keyboards 19 and 20 are provided. In another embodiment, cathode-ray tubes replace the stroboscopic indicators. In view of the low-frequency width permissible in telephone systems, signals may be transmitted at a low speed for recording on the storage device, the speed of which may be increased subsequently to provide for the visual indication. Specifications 786,033 and 786,034 also are referred to.

Abstract: 1475422 Recovering paper fibres BLACK CLAWSON CO 23 Aug 1974 [27 Aug 1973] 37256/74 Heading D2A  To recover paper fibres from material containing waste paper, the material is fed to a pulper 10 where it is mixed with water to a consistency of 2-8% and slushed rather than completely defibred, the resulting slurry being passed through ¢-2 inch holes in an extraction plate 12, optionally centrifugally cleaned at 22 to remove high density contaminants, and screened at 25, the accepts being passed for refining and the rejects (a 20-80% fraction) being fed to a defibrer 44, e.g. a disc refiner, and a tailing screen 45 where non-fibrous material such as plastics are eliminated, the fibrous accepts from screen 45 being recycled at 47 for screening at 25. As shown the screening at 25 is performed by a cylindrical screen 40 having a high speed internal rotor 41. The inlet port 31 and the discharge port 36 are directed tangentially to the screen and a valve 37 in the discharge port 36 provides for regulation of the proportions of accepts and rejects. The screen 40 either has 0.022 in. wide slots or holes of diameter in the range 0.050-0.079 inch. The perforations of tailing screen 45, which may be a vibrating flat bed screen, are rather larger, e.g. # in.

Filed: 1958-11-20
Abstract: 837,394. Facsimile scanning apparatus. CREED & CO. Ltd. Nov. 20, 1958, No. 37340/58. Class 40 (3). In a facsimile scanning arrangement in which a message form on the surface of a drum moves relatively to a transducer head a towing device is employed to move the message form relatively to the drum which is either fixed or mounted freely on its axis. In this manner the inertia of the moving elements is much less than in conventional systems in which the drum itself is driven. Figs. 1 and 1a show one embodiment in which the message form 28 is gripped at two extreme positions along the leading edge between clamps 17, 18 carried by arms 9, 10 which are rotated about a rigid shaft 2, the former by means of a driving shaft 14 and gears 11, 13 whilst the arm 10 is rotated by means of a gear 16, shaft 15 and a train of gears similar to 11, 13, the clamps, which form a towing bar, moving in the annular space between a drum 1 rigidly attached to shaft 2 and a hollow rigidly mounted cylinder 5. The latter is provided with a slot 6 through which the stylus 57 (Fig. 3) projects as the transducer head 58 moves along the slot to effect one component of scanning the other component of which is constituted by the movement of the message form around the drum 1 a roller 30 serving to maintain the form in position against the surface of the drum adjacent the scanning position. In order to prevent the clamps from damaging the stylus a cam-operated switch may be arranged to apply a potential (equivalent to that for producing a " space ") of sufficient intensity to lift the stylus away from the message form during the passage of the clamps past aperture 6. In an alternative arrangement the surface of the drum is provided with a spring-tensioned movably mounted longitudinal sector 34, Figs. 2 and 3, and the clamp supports modified as shown in respect of the arm 9 (Fig. 3) by providing a secondary arm 43 pivotally mounted at 44 and having a cam follower 51 which engages the surface of a cam 53 as the arm 43 passes under the gap 6 thus forcing the clamps against sector 34 and depressing the latter by an amount sufficient to allow the clamps to move, inwardly, and clear the stylus 57. Fig. 4 shows a second embodiment in which the drum 1 is freely mounted on shaft 2 via a ball race 60 (at each end) the shaft, which in this case is driven by motor 62, supporting and driving a towing bar 59 around the leading edge of which the message form is secured by bending (Fig. 5B, not shown), by means of spring clips (Fig. 6, not shown), by means of snap fasteners (Fig. 7, not shown) or by means of an adhesive applied directly to the message form (Fig. 8, not shown) or by means of a strip of adhesive material (Fig. 9, not shown). To prevent lateral movement of the message form each end of the bar 59 may be provided with a flange (Fig. 5A, not shown).

Title: Improvements in or relating to gas detector devices
Inventor: GROSSKOPF KARL
IPC: G01N31/22
Filed: 1960-11-07
Abstract: <PICT:0910926/III/1> A gas detector comprises a longitudinally extending container divided into two or more juxtaposed longitudinally extending chambers which contain frangible reagent ampoules covered with an absorbent material, such as cotton, wool, synthetic resin fibres, or filter paper, which may contain silica gel.  When used, the container can be broken or deformed so breaking the ampoules, and allowing the reagent to be absorbed by the absorbent material. Gas to be tested is then drawn through the container in contact with the reagentbearing adsorbent.  The container may be a flexible tube, or a glass tube covered with a transparent flexible sleeve where it is designed to be ruptured; the ampoules may be glass. Gaseous impurities are detected by drawing gas through the device, so that a colour is produced on the absorbent material, resulting from reaction between the reagent and the gaseous impurity; in this way more than one gas may be detected at one time. As shown in Fig. 1, a flexible container 1 having breakable glass seal 3 and 4 is provided with a flexible Y-shaped insert 2 which divides the container into three channels. In each channel is placed a glass reagent-bearing ampoule covered with a fabric stocking.  In the examples (1) cyanogen chloride is detected by a solution of 4-benzyl pyridine and barbituric acid in acetone, the absorbent being untreated cotton; (2) phosgene is detected by a solution of N-phenyl-benzylamine in alcohol the absorbent being cotton impregnated with sodium carbonate; (3) lewisite is detected by a solution of Michler's thioketone in alcohol, the absorbent being untreated cotton; (4) nitrogen mustard gas is detected by a solution of Dragendorf's reagent (potassium bismuth iodide) in ethyl acetate or ether, the absorbent being filter paper impregnated with silica gel.

Abstract: 383,976. Colour photography. THORNTON, J. E., 8, Hill Street, Jersey. July 11, 1931, No. 19971. [Class 98 (ii).] Two-colour photographs or kinematograph films are produced on lenticular films, and projected therefrom, with the aid of a filter comprising orange-red and blue-green and component colours. Filters of known form are used, such as a cell divided by an adjustable partition into two compartments containing coloured solutions, or dyed gelatin films cemented on or between glass with a narrow black band between the colour areas or an overlap at adjacent edges of these areas which produces such a band. The filter may comprise two wide colour bands, or a large number of alternating coloured lines. The pictures may be taken on films having linear or picot lenticles. The positive film may be produced from the negative by reversal, which is stated to yield fine-grain results ; but preferably it is produced therefrom by contact or projection printing, using similar film material and a source giving parallel light falling normally on the printing zone or at an angle thereto. Various known methods are specified for avoiding moire patterns when printing, the preferred method being that of using a negative film having longitudinal linear lenticles and a positive film having transverse linear lenticles. For projection, a two-colour filter may be used in which the orange-red and blue-green components have a slight spectral overlap in the centre in the region of yellow.

Abstract: 1,155,019. Urethane derivatives of thiazolidines and process for their preparation. R. B. WOODWARD. 30 Aug., 1966 [9 Dec., 1965], No. 38572/66. Heading C2C. Compounds of the formula in which Ac represents an acyl group, X stands for the disubstituted carbon atom of the thiazolidine ring, R 1  stands for a free or functionally converted carboxyl group and R a  stands for the residue of an alcohol, may be obtained by reacting a compound of the formula wherein Rb is the residue of an alcohol with a nitrosating agent and treating the resulting product with a basic agent. The process may be effected by reacting the starting material with the nitrosating agent, e.g. a nitrosyl halide such as nitrosyl chloride, nitroso fluoborate or nitroso perchlorate, preferably in the presence of a base such as pyridine, or of an alkali metal nitrite in the presence of an acid, e.g. acetic acid. The resulting intermediate containing a nitroso group, which in one embodiment may also be employed as a starting material, may be converted into the desired product simultaneously or subsequently by treatment with a base, e.g. an alkali metal carbonate, bicarbonate or hydroxide or an organic base such as pyridine: the base may also serve as a solvent or a further solvent may be added and the reaction may be carried out at a reduced or ambient temperature, optionally in an inert atmosphere. A resulting mixture of isomers may be resolved by conventional methods, e.g. fractional crystallization or adsorption chromatography; resulting racemates may be resolved by forming a mixture of diastereoisomeric salts with optically active salt-forming agents, separating the mixture into the diastereomeric salts and converting the isolated salts into the free compounds. In specific examples the only examples of the radicals Ac and X which are described are the t-butyloxycarbonyl radical and a dimethyl-substituted carbon atom respectively. The products of the invention may be chemically modified by conventional methods, for example an ester radical R 1  may be converted to the free acid or a free acid radical R 1  may be converted to a functional derivative, many of which are described, e.g. ester, amide, azide, hydrazide, nitrile, azocarbonyl or azidocarbonyl.
