IPC: D06P5/24
Filed: 1928-02-03
Abstract: 284,676. Sadtler, H. S. Feb. 3, 1927, [Convention date]. Transfers.-A transfer for use with fabric or other absorbent material consists of a non- absorbent paper printed with a paste or ink containing a water-soluble dye, the printed surface being dusted over with a powdered carbohydrate; alternatively, the carbohydrate can be incorporated in the ink. A non-drying ink, containing glycerine, an inert, soluble, colloidal thickener, e.g. sugar, dextrin, gum, or starch paste, or a mixture of the two, is employed, and the dye is preferably one that is rendered fast by steaming. Designs in one or more colours may be printed on material such as grease-proof parchment paper. The printed surface is dusted with powdered gum arabic, tragacanth, sugars, or dextrin in order to dry the ink, and prevent offsetting, and also to facilitate the penetration of the dye into the wetted surface during transferring. Mordants, such as tannin or metallic salts, may be incorporated in the ink. According to the Specification as open to inspection under Sect. 91 (3) (a), the printing with an ink containing a colloidal thickener is effected in the heated state. This subject-matter does not appear in the Specification as accepted.

Filed: 1918-02-27
Abstract: 123,415. Day, D. T. Feb. 27, 1918 Mineral and tar oils; extracting.-Oils and other hydrocarbon products are extracted from shale, coal, &c., by treating the shale &c., prior to destructive distillation with the vapours, which may be partially condensed, obtained by the distillation process. The condensation of the vapours is completed in passing through the shale, and the hot condensed liquid dissolves part of the oil &c. from the shale, and this is separated from the solid material prior to the feeding of the material to the distillation retort. As shown, the shale is fed by a band 3 to a retort 1, and oil vapours &c. are fed into this retort by a pipe 14. The condensed oils &c. pass down through the shale and are passed through screens 6, 7 to a conduit 5 with a liquid seal. The shale with part of its oil &c. dissolved is passed to a retort 8 being fed through the same by a screw conveyor. The retort 8 is heated in an oil or gas furnace 9, and may be supplied with superheated steam from a generator 18 and superheater 19. The gaseous products are led away by pipes 12, 13, 14, and tar products may be run off by a pipe 15 instead of being led through the pipe 16. Specification 119,648 is referred to.

Title: Manufacture of artificial resins from phenols and aminotriazines
IPC: C08G14/06
Filed: 1942-03-19
Abstract: Resinous condensation products are made by heating an aminotriazine and o-cresol or a xylenol or higher homologue of phenol, which cannot be converted by ordinary methods into formaldehyde condensation products, with formaldehyde.  Suitable aminotriazines are melamine and the mixture obtained by heating cyanamide or dicyandiamide in an open vessel.  The phenol or the aminotriazine may first be partially condensed with part or all of the formaldehyde and the other components then added, if necessary with further formaldehyde. Alternatively, the phenol and the aminotriazine may be separately condensed with formaldehyde, the products mixed and further condensed.  In an example, xylenol is mixed with neutralized formaldehyde and heated at 90-97 DEG  C. with melamine.  Water is removed by distillation in vacuo and the fluid resin coloured with an aqueous solution of Nigrosine K powder and kneaded with a mixture of wood meal, zinc or calcium stearate and magnesium oxide and dried to give a moulding powder.

Title: An improved contrivance for rolling cylindrical sheet zinc casings
IPC: B21D51/36
Filed: 1926-02-10
Abstract: 248,719. Sachs Ges., R. March 6, 1925, [Convention date]. Hollow-ware.-An apparatus for forming sheet zinc casings for the cells of electric pocket batteries of the type consisting of a mandrel mounted in the bore of a block into the space between which a metal blank is pushed so as to bend the blank into tubular form, has mounted over a guideway communicating with the space, a cover, which is lowered prior to pushing the blank forward, so as to prevent the formation of creases. A metal strip 6 is fed along a guide 5 to an end stop 25, whereupon a shear blade 11 carried by a cover 12 is pushed down against the action of springs 13 by the cam surface 17 of a bar 16 operated by an eccentric, so as to sever a blank which drops on to a guide 10. A series of pushers 9 which are guided by a cross-head slidably mounted in a slot 18 in the bar 16, are then moved forward by the bar 16 so as to push the blank into the channel 4 between the cylindrical bore of a block 3 and a mandrel 1 and thus bend it into tubular form with its ends overlapping. The pushers move in slots in the block and in grooves in the cover. The cover prevents creasing of the blank during bending. The mandrel has a rotatable sleeve 2 from which the blanks are stripped on to an enlarged part 24 by a sleeve 21 pushed forward by a cam-operated lever 23. The joint may be soldered on the part 24 or may be stripped therefrom. The blank may be rotated so as to bring the seam underneath prior to soldering or may be bent with its seam underneath by constructing the machine so that the blank is pushed along a guide adjacent the under side of the mandrel.

Patent GB-556911-A (GB)
Title: Improvements in and relating to actuators for automatic fire extinguishing systems
IPC: A62C35/60
Filed: 1942-03-24
Abstract: 556,911. Fire-extinguishers. SPECIALTIES DEVELOPMENT CORPORATION. March 24, 1942, No. 3903. Convention date, March 19, 1941. [Class 47 (ii)] An actuator for pneumatically responsive fireextinguishing medium releasing means comprises a plurality of devices responsive to different predetermined condition associated with a fire in its early stages viz. an explosion, a predetermined high temperature or a steep temperature rise and includes a variable volume chamber having a movable wall which is actuated by any of the responsive devices in a manner to decrease the volume of the said chamber to set up an air pressure therein. The actuator has a cup shaped body 5 carried by a ring 3 for mounting it on the ceiling &c and has secured against its slightly conical base by means of a clamping ring 6 two diaphragms 36, 37 spaced apart by a ring 38 and central discs 39. The space 45 between diaphragm 37 and the cup base constitutes the variable volume chamber referred to above and communicates by a tube 4 to the pneumatic responsive releasing means. Also mounted within the cup 5 are a cam 10 under influence of a spring 12 and normally held in non-actuating position by an offset 15 on a spring influenced trigger lever 16 and a spring-pressed trip member 21 normally held in inoperative position by a bi-metallic element 26. the event of an explosion the air wave strikes through a gauze cover 66 on to a flexible disc 65 bearing on an arm 18 of the trigger lever 16 which releases cam 10 and enables it to be rotated by spring 12 and to exert pressure on the diaphragms causing a pressure wave in the chamber 45. Secondly, a predetermined high temperature flexes the thermostatic element 26 thus releasing the trip member 21 for actuation by its spring 23, the trip member freeing the trigger lever 16 from cam 10 thus again setting up a pressure wave in chamber 45. Finally, a steep rise of temperature in an annular air bulb 55 communicating with the expansible chamber 49 between the two diaphragms causes pressure to build up in chamber 49 faster than it can dissipate through a leak port 52 whereby diaphragm 37 is moved away from diaphragm 39 again setting up a pressure wave in chamber 45. Cam 10 is reset by a lever 33, and trip member 21 by a projecting lever 24.

Abstract: 398,499. Automatic regulation ; rectifying alternating currents. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Willis, C. H.; 1080, Waverly Place, Schnectady, New York, U.S.A.) Feb. 10, 1932, No. 4004. Convention date, Feb. 14, 1931. [Classes 38 (ii) and 38 (iv).] The voltage of an alternating-current generator is automatically regulated by varying its field excitation which is controlled by a pair of grid controlled arc discharge tubes 18, 19 arranged for full wave rectification and supplying rectified current to the excitation or exciter circuits of the alternator 12, the grid and anode voltages of the discharge tubes being relatively variable in phase, and a glow-discharge tube 28 in the grid circuits, responsive to the supply voltage being arranged to charge condensers 23, 24 having leak resistances 26, 27 in the grid circuits so as to produce a variation in the excitation which opposes the voltage variation. A battery 25 maintains the valves fully conducting' when the tube 28 is not conducting. Conduction of the tube charges the condensers. 23, 24 so as to block or reduce the conductivity of the valve to ignite next and thus reduce the excitation. A condenser 32 suppresses unidirectional components so as to maintain the breakdown voltage of the tube 28 the same for positive and negative half cycles. A condenser 33 and parallel resistance 34 may be inserted in series in grid circuits so that the time constant of the corona tube circuit is the same as that of the slowest field winding on the generator or its exciter so as to prevent the voltage hunting. The Specification as open to public inspection describes a single rectifier tube controlled by a corona tube connected across a condenser paralleled by a leak resistance across the grid-cathode circuit of the tube, the time constant of the grid circuit being equal to the period of one half wave of the A.C. Specification 358,569 is referred to.
