Title: Improvements in or relating to the manufacture of sliding clasp fasteners
IPC: B05D7/16
Filed: 1932-05-03
Abstract: 401,315. Sliding-clasp fastenings. NAUNTON, W. J. S., 40, Perrymead, Prestwich, Manchester, and LIGHTNING FASTENERS, Ltd., Imperial Chemical House, Millbank, London. May 3, 1932, No. 12709. [Class 44.] A sliding-clasp fastening of the type in which interlocking elements on two flexible stringers are engaged and disengaged by a slider mounted on both stringers has the interlocking elements made of metal and coated, when mounted on the stringers, with an adhesive non-metallic substance or composition which is subsequently hardened. The coating does not fill the gaps between the elements. The interlocking parts of the members if already of full size are prevented from being coated by being interengaged before the coating process takes place. A suitable coating is a solution of a rubber mixture which is vulcanized on to the elements by subsequent heating and which may be bonded thereto by an acid action. Colouring matter is added to the solution. The rubber may be electro-deposited. Specifications 344,401 and 357,238, [both in Group V], are referred to.

Title: Improvements in and relating to bedplates for the manufacture of roofing tiles
IPC: B28B7/00
Filed: 1934-04-27
Abstract: 417,316. Pallets for moulding tiles. POWEL, W. S., 110, Canterbury Road, Croydon, and ATTWOOD, E., 26, Eversfield Road, Reigate, both in Surrey. April 27, 1934, No. 12815. [Class 87 (ii).] A bedplate or pallet for moulding roofing tiles has its surface 4 curved both laterally and longitudinally. All parts may be of equal curvature so that the surface is a portion of a sphere, or the curvature may be flatter in one direction than in the other. The pallet may accommodate more than one tile either in sideby-side or end-to-end relation. A flange 5 may be provided round the pallet and may have a flat edge or be provided with flats at the corners and centres of the ends so that the pallet may bear evenly on guide runner surfaces of a tilemoulding machine. Lugs are formed on the tile by cylindrical depressions or slots 6 at one or more edges and projections on the surface may form weakened portions in the tile which are pressed through to engage fastenings on a roof. The tile material may be fed beneath a roller curved to correspond with the pallet which may also pass over a bridge or curved portion on the guide runners in a curved path relative to the, or an additional, roller so as to shape the tile surface in the plane of movement. The pallet may be cast or moulded from metal or other material or stamped from sheet metal.

Title: Improvements in or relating to mixing valves
IPC: G05D23/13
Filed: 1938-04-29
Abstract: 502,222. Thermally-actuated valves. THERMO-MIX, Inc. April 29, 1938, No. 12852. Convention date, Dec. 21, 1937. [Class 135] A valve for mixing fluids of different temperatures comprises a casing 10 enclosing a housing 34 having parallel conduits 44, 46 which direct the fluids through slits 60, 62 in a bushing 56 fixed in the housing, the flow being controlled by a vane '66, rotated within the bushing by thermo-responsive means 100 subjected to the temperature of the mixed fluid, The fluids enter by branches 22, fitted with check valves and strainers 26, and the mixed fluid escapes into the casing 10 and to the branch 99 through openings 92, 96 in the top and ends of the bushing 56 respectively. By disposing these openings above the vane 66 only, the fluid trapped below the vane damps its movement in the event of sudden changes of pressure. Additional damping is provided by a dash-pot 84, the piston 86 of which is connected to an arm 78 on the spindle of the vane 66. The opposite end of the arm is connected by a link 106 to one end of the bi-metallic strip 100 and movement of the arm is limited by stops 110. The position of the other end of the strip 100 is determined by the setting of a pointer, movement of which rotates a plate (not shown) having a cam slot engaged by a pin 114 on a link 102 fixed to the strip. In a modification, a three-armed vane, co-operating with three pairs of slits 60, 62, is used.

Title: Production of organic isocyanates
Inventor: CLIFFORD BARBARA HELEN
IPC: C07C263/10
Filed: 1964-03-26
Abstract: In the manufacture of an isocyanate by reaction of a primary amine with phosgene, the isocyanate is present at the commencement of the reaction, and at all times during the reaction in amount at least equimolar to any amount of amine added.  Inert solvents may also be present, the amount of isocyanate being at all times at least 12% by weight of said solvents. These include hydrocarbons, chlorhydrocarbons, ketones, chlorketones, esters of carboxylic and carbonic acids.  The reaction may be in stages at different temperatures, e.g. first at 0-50 DEG  C., then 90-160 DEG  C.  The amine may be added, alone or as a salt or as a solution or dispersion in a solvent, to a solution of phosgene in the isocyanate. The amount of phosgene is usually more than 2 mols. per amino group. Many aliphatic and aromatic mono-, di- and poly-amines are specified as is tetrahydrofurfuryl amine, while in an example 2,4-tolylene diamine is converted to the di-isocyanate.

Abstract: 709,934. Supply meters; power measurements. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. March 5, 1952, [May 31, 1951.] No. 12904/51. Class 37. A circuit arrangement for metering, indicating, or controlling in response to volt-amperes or volt-ampere-hours in polyphase circuits comprises a meter or relay of the D.C. wattmeter type having its current and voltage coils energized from the polyphase circuit through polyphase rectifiers. A dynamometer wattmeter 5 has cooperating current and voltage coils 6, 7 connected in the output circuits of polyphase rectifiers 8, 16. The input leads 9, 10, 11 of the current recifier 8 are connected to the secondary winding of current transformers 12, 13, 14, the primary windings of which are connected in the phase conductors 1, 2, 3 of a three-phase circuit. The secondary windings are star connected, the star point being connected to a centre tapping on the current coil 6 in order to obtain accurate response to unbalanced conditions. The input leads 17, 18, 19 of the voltage rectifier 16 are connected through resistors 20, 21, 22 to the phase conductors 1, 2, 3. In the case of a four-wire system a centre tapping on the voltage coil 7 is connected to the neutral conductor 4. Alternatively the rectifier 16 may be energized from the phase conductors by means of voltage transformers, the centre tapping of the voltage coil 7 being connected with a star point of the secondary windings. The transformers 12, 13, 14 may be auxiliary current transformers energized from main transformers in the phase conductors 1, 2, 3. Instead of the coils 6, 7 being centre-tapped they may be shunted by resistors or impedances which are centre-tapped. The meter or relay 5 may be of the dynamometer, mercury meter, or pendulum type.

Title: Improvements in printing plates
IPC: B41C3/06
Filed: 1943-08-11
Abstract: 567,470. Printing-surfaces. WAXEDPAPERS, Ltd., and RALSTON, W. Aug. 11, 1943, No. 13014. [Class 100 (ii)] Printing-surfaces are formed by moulding or casting from a plastic material such as cellulose acetate or like non-fibrous film materials, or synthetic resins, and uniting to the rear of the cast plate one or more backing layers of flexible material. Bonding layers of cotton mesh, or wire mesh, are inserted between the facial and backing layers. In one method, a thermoplastic material is moulded from sheet or powdered material, together with an impressed layer of fabric, and a sheet of rubber, in a heated press which units the materials and vulcanizes the rubber. The vulcanized rubber layer may be attached by rubber cement. In another form, a plastic substance dissolved to form a viscous solution is evaporated in a mould, and a fabric backing pressed therein. A rubber backing is cemented to the finished product. The above methods may be modified by applying a rubber sheet directly to the back of the facial layer and superimposing a sheet of cotton or other fabric on the rubber sheet. Composite plastic and fabric surfaces may be attached to a rubber printing roller or flat plate, and one plate may complete the periphery of a cylinder. The backing material may terminate short of the edges of a plate, and the plastic material is thickened in this region to provide a reinforcing bar which is drilled for the reception of fixing screws and which will resist buckling of the transverse edge of the plate between the screws.
