Title: Counting apparatus
IPC: D01H13/32
Filed: 1956-07-23
Abstract: 840,963. Counting-apparatus. DEERING MILLIKEN RESEARCH CORPORATION. July 23, 1956 [July 22, 1955], No. 22762/56. Class 106 (1). A counter for counting the number of knots tied by the operator of a yarn-winding machine by counting the number of machine starts is provided with means for preventing the registration of a start during predetermined periods immediately following the stopping or starting of the machine. As shown, a main power switch 36 is normally closed to energize a delay relay 35 which keeps a power supply contact 34 closed. When the machine is inoperative, a contact 25 is open and on starting the machine, the contact 25 closes to energize a relay 43, thereby changing over a contact 45. A motor M is thus energized to rotate slowly in an anticlockwise direction a shaft 56 carrying cams 39, 49, 59. The cam 59 is then operative to complete a holding circuit for the motor by lowering of an arm 61 and the cam 39 is operative to lower an arm 31 thereby energizing the coil of an electromagnetic counter 21. The cam 39 has a reduced radius portion corresponding to a four-second interval so that should the operator stop the machine in order to tie a knot in a broken yarn, a count cannot fail to be registered when he starts the machine again. The arms 31, 61 are raised approximately simultaneously to de-energize the counter coil and open the motor holding circuit, the motor continuing to run until the cam 49 raises the arm 51 out of engagement with the contact 52. If machine is now stopped thereby opening the switch 25, a circuit for the motor is completed via contacts 46, 53 and the motor runs until the arm 51 is lowered to engage the contact 52, the registration of a start being inhibited during this period since the arm 31 is raised, thereby preventing a " start " being incorrectly registered by closure of the switch 25 during the period of coming to rest of the yarn take-up package of the machine. The delay relay 35 is of a type which cannot be re-actuated until a predetermined period has elapsed after de-actuation, thereby preventing a count being registered while the arm 31 is lowered by interrupting the power circuit. An arrangement is described for connecting selectively a small number of counters to a large number of winding-machines in different combinations, the delay period due to the reduced portion of the cam 39 preventing, for two machines connected to the same counter, the registration of a second count from a second machine for a predetermined period after registration of a first count by a first machine.

Title: Improvements relating to apparatus for treating liquids which contain solid matter
Filed: 1949-09-02
Abstract: 666,444. Wet grinding. NORDELL, C. H. Sept. 2, 1949. [Nov. 9, 1948] No. 22815/49. Class 59. [Also in Group I] Lumps of solid matter carried by a stream of sewage in an influent channel are inter.- cepted as the stream flows to an effluent channel 3, Fig. 3, by a drum screen 5 associated with a transfer andcomminuting unit 81, 82, 89 disposed adjacent to the upstream surface of the screen 5 for removing solid matter and comminuting it away from the screen which is mounted on shaft 25 for relative rotation, as by motor 29 through reducing gears, with respect to the unit so that substantially the whole upstream surface of the screen is periodically swept by the unit. The comminuting unit comprises a rotatable cutting cylinder 81 rotated at a higher speed than screen 5 from the motor 29 by a driving shaft having a split coupling 75 therein which enables the unit 81, 82, 89 to be swung away from the screen 5 and out of the sewage, e.g., for inspection and repair. To this end a hand- or motor-driven worm 104 on a stationary part of the framework engages with the worm-wheel 105 secured to a member 95 on which the unit is rigidly mounted . An adjustable stop 109 carried on the member 95 positions the unit with respect to the screen 5. The rotary cutting cylinder consists of a stack of identical toothed discs 81, Fig. 7, mounted on a shaft and separated by spacers 88, Fig. 9. The discs 81 each have at least two internal notches 84, 85 asymmetrically disposed with respect to the teeth and adjacent discs are assembled on the shaft with different notches engaging a single key or spline 86, Fig. 9, so that the teeth are in staggered relationship. The cutting cylinder co-operates with a non-rotatable abutment 89, Figs. 8, 9, in the form of a comb interdigitated with the toothed discs. The peripheral surfaces of the spaces 88 may be roughened so as to sweep solids and particularly rags away from the screen 5 and wrap them around their own peripheries to be engaged by the cutting teeth 94 of the comb 89 and the screen bars 8 of the screen 5 and web members 7 supporting the annular bars 8 Specification 661,443 is referred to.

Title: Method of preparing silver halide geltine emulsions for the silver dyestuff bleach-out process
IPC: G03C7/28
Filed: 1938-08-02
Abstract: 517,628. Colour photography. KODAK, Ltd. Aug. 2, 1938, No. 22845. Convention date, July 31, 1937. [Class 98 (ii)] A thin silver halide emulsion layer having a high silver halide content for the silver dyestuff bleach-out process is produced by centrifuging an emulsion containing at least 6 per cent., preferably at least 10 per cent. of gelatine, dispersing the silver halide grains thus removed to produce a coloured gelatine dispersion and coating on a support. In a modification the unwashed silver halide grains produced by centrifuging a gelatine-silver halide emulsion are dispersed to produce the coloured gelatine dispersion. In an example green-sensitized high contrast emulsion is centrifuged for ten minutes, 90 per cent. of the silver halide grains are recovered on the centrifuge walls ' and are dispersed in gelatine dyed with Algol Pink BBK. The dyed emulsion is coated on a transparent support. Dispersions of red- and bluesensitive emulsions may be similarly prepared and coated on glass, cellulosic material, or paper. Vat or azo dyes of colours complementary to the colour sensitivity may be used to colour the layers.

Title: Improvements in or relating to vinylidene chloride interpolymers as coatings for regenerated cellulose film
IPC: C08J7/052
Filed: 1948-08-30
Abstract: A copolymer for the moistureproof surface coating of regenerated cellulose film is prepared by polymerizing a mixture of 1 to 15 per cent by weight of vinyl acetate or of 2-hydroxy-ethyl acrylate, 5 to 15 per cent of acrylonitrile and 70 to 94 per cent of vinylidene chloride, the copolymer being hydrolysed when vinyl acetate is employed.  The process may be effected in bulk, solution or aqueous emulsion, with catalysts and activators, e.g. ammonium persulphate and sodium metabisulphite. Sulphated methyl oleate is specified as an emulsifying agent. Ethyl, lauryl or tert.-dodecyl mercaptan modifiers may also be used to improve the solubility and viscosity.  Hydrolysis may be effected by dissolving the copolymer in dioxane at 50 DEG  C., adding methanol and sulphuric acid, and refluxing for several hours. The resulting copolymer is coagulated with water.  Slip agents, pigments, dyes, plasticizers and delustrants may be incorporated in the copolymer composition which may be applied to the base film as an aqueous dispersion or as a solution in an organic solvent, e.g. dioxane or a mixture of methyl ethyl ketone and toluene.

Title: Improvements in and relating to means for mounting or fastening structural and/or decorative articles
IPC: F16B5/06
Filed: 1947-08-18
Abstract: 660,104. Brackets. MONCKTON, J. Aug. 18, 1947. No. 22876/47. Class 52 (v). [Also in Groups XV, XXV and XXX] Means for mounting or fastening articles provided with a cavity upon a supporting surface comprises one or more pairs of mounting fittings, each fitting comprising a base 2 two strut-like 'portions 4 and a spike 3 extending from each strut, the arrangement being such that when the bases of a co-operating pair of mounting fittings engage the supporting surface the struts are flexed to allow the spikes to pass through slots or perforations in the article so that they press against the walls of the cavity in opposed directions to hold the article securely in position. As shown in Fig. 11 the bases may engage lugs 20 to hold them in position. When rail-like elements are joined an alignment fitting such as shown in Fig. 14 is used. The alignment fitting comprises an inverted T-shaped member 32 in which the edges of the web and of the flanges contact the boss of the elements 33, 34. The flanges have slots 35 for the mounting fittings which pass through perforations in the elements. In another form of alignment fitting a bush 40 aligns the elements 41, 42 while a loose rectangular wire loop 43 embraces the mounting fittings 44 and thus acts as a locking member to keep the elements 41, 42 from separating. Specification 588,412 is referred to.

Title: Improvements in electromagnetic relays
IPC: H01H29/16
Filed: 1935-08-19
Abstract: 445,007. Electromagnetic switches. AKTIEBOLAGET HG. RELAY PATENT, 18, Norrlandsgatan, Stockholm.-(Assignees of Meyer, S. F. E.) Aug. 19, 1935, No. 23302. Convention date, May 24. [Class 38 (v)] [See also Group XL] An electromagnetic relay in which the closing and opening of the circuit is effected by means of a rod - like armature movable through the centre of a magnet coil has polar extensions arranged at opposite sides of the coil in order that the armature when magnetized will be brought by the influence of such poles into a position in which it will drop into its definite displaced position. As shown in Fig. 1, the coil 4 on energization causes the attraction of the rod 5 through its centre. Above the coil is a magnetic plate 6 with ends turned down over the inclined sides of the container 1 so that the rod 5 is retained attracted in its oppositely displaced position until the magnet is de-energized. On release the rod falls and bridges mercury contacts on cups 2, 3. A similar action occurs in the return movement the rod being held in position ready to drop by the attraction of the opposite end of the bar 6. For use with a relay of the type described an indicator constructed as shown in Fig. 4, may be used the electromagnet 4 of which is connected in shunt or series with the relay electromagnet. The bar armature 5 of the indicator is arranged to rest on a contact 9 or 10 in its two positions, the outer end of the bar when at rest being a short distance below an upper electrode 7 or 8 formed as a letter. The tube 1 is filled with a gas such as neon so that a glow surrounds the letter below which the armature rests the other letter remaining dark. Thus an indication of the relay position may be given. An indication of the relay operation may, alternatively, be given by journalling the tube on an axis passing transversely through the centre so that the tube changes its position as the armature moves.

Title: Improved manufacture of methane
IPC: C07C1/06
Filed: 1920-08-10
Abstract: The process of the parent Specification for manufacturing methane from carbon monoxide and hydrogen, is modified by diluting the mixture with gases that are indifferent to the process in order to regulate the temperature of the reaction, more particularly in the earlier stages.  The dilution may be effected by employing a quantity of hydrogen, as compared with carbon monoxide in excess of the proportion, 1 : 5; or the gases may be diluted with methane, which may be derived from the process itself.  In the latter case, the gases may be repeatedly passed through a single contact furnace, the water and a proportion of the highly concentrated methane being withdrawn after each passage, while to the entering gases are added quantities of carbon monoxide and hydrogen equivalent to the methane withdrawn, the relative proportions of carbon monoxide and hydrogen in the reaction gases being maintained at about 1 : 5; the last traces of hydrogen in the methane may be subsequently removed.
