Abstract: 359,370. Mercury-vapour rectifiers. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. May 5, 1931, No. 13232. Convention date, May 23, 1930, [Class 39 (i).] To reduce back-ignition, the dead space between the anode bar b and the sleeve e is superheated by a part of the anode bar, the cross section of which is sufficiently reduced to enable it to be heated by the anode current. The anode bar also serves to restrict conduction of heat from the anode. The sleeve e is mounted on an insulator d through which passes a lead-in c connected to the anode bar through a screwed nipple f. Overheating of the insulator is prevented by extending the length of the anode bar. The anode may be integral with the anode bar and formed by shaping, moulding, or pressing a graphite body.

Abstract: 817,062. Calculating - apparatus. STANDARD TELEPHONES & CABLES Ltd. April 26, 1957 [April 28, 1956], No. 13368/57. Class 106 (1). An accounting machine associated with means, such as a punch, for recording data set up in the machine in a mechanically-readable form has a travelling paper carriage on which is mounted a bar adjustably carrying control projections for controlling the operation of the machine and an additional bar also carrying projections which co-operate with contact devices mounted in the body of the machine to signal to the associated recording means the movements of the carriage. In an arrangement described, the additional bar, which may be one of several interchangeable bars, can receive a projection in any columnar position and in any of seven rows. The projections of these rows co-operate respectively with seven levers 3 pivoted about a common axis in a box 4 carried by the machine itself. When a projection engages a lever 3, the latter is rocked to actuate a corresponding contact set 5. The projections of the first two rows signal the direction of movement of the carriage, and for this purpose are bevelled in opposite senses or displaced relative to one another in the direction of carriage movement so as to actuate their contact sets in sequence and in accordance with the direction of movement. Other rows may be used to signal permitted initial positions of the carriage, carriage return movements and skipping of columns, whilst the last row may be used to suppress recording in the associated means.

Title: A method of casting articles from liquid elastomers
Inventor: RUSS PAUL EDWARD
IPC: B29C39/08
Filed: 1964-04-01
Abstract: 1,033,594. Driving belts. GATES RUBBER CO. April 1, 1964, No. 13421/64. Heading F2Q. [Also in Division B5] Articles such as tyres and power transmission belts, cogged or of V section, Fig. 5 (not shown), are cast from a viscous polymerizable elastomeric material in a moulding apparatus which comprises a shell mould 15 and mandrel 14 held in spaced relationship by gravity, mechanical or magnetic means and mounted for rotation on a shaft 13, material being introduced through a pipe 17 to land on a plate 18 and from thence being urged into a vacuumized cavity 19 by centrifugal force. Air is withdrawn from vacuum chamber 11 via an exhaust line 16. Preferably the mould and cavity 19 are maintained at a raised temperature e.g. 200‹ F., to facilitate the flow of the material without, however, unduly increasing the rate of polymerization. The inner surface of the shell 15 is shaped to give the article its requisite profile and when reinforcing material 22 is used, Fig. 4 (not shown), this is wound in one or more layers on to the mandrel 14 which preferably has a corrugated profile 20, 21. Among reinforcing materials mentioned are fabric, natural or synthetic fibre, wire, cotton, or cords of rayon or nylon. In the case of cord-like material the mandrel 14 may be helically grooved to provide a seating therefor. Preliminary curing is carried out by removing the article, shell 15 and mandrel 14, heating them and removing shell 15 before curing is complete. The centrifugal action of the moulding process may be utilised to form laminated products by using a material having components of differing density so that e.g. a cogged belt may be formed wherein the cogs are of relatively hard material. Suitable polymerizable elastomeric materials are plastisols, organosols, liquid chloroprenes, liquid polysulphides, depolymerized natural rubber, silicones, epoxides, urethanes, carboxylated butadiene-acrylonitrile, polyester based resins and polyether based resins. Preferably the polymers are degassed before the polymerization agent is added.

Title: Method of making negatives for use in the production of photomechanical printing plates and photographic prints
IPC: G03F1/92
Filed: 1933-05-09
Abstract: 419,362. Photomechanical printing- surfaces. PFOST, K., 101, Alexandrinenstrasse, Berlin. May 9, 1933, No. 13448. Convention date, May 10, 1932. Drawings to Specification. [Class 98 (ii).] In a method of preparing negatives for making photomechanical printing-surfaces and photographic prints, the picture - forming elements of a design or picture are cut in wood block and the surface of the block is coated with ink and printed directly onto a transparent carrier. The opaque parts of the negative so formed may be coated with opaque material, e.g. soot or metal powder. In carrying out the process, a wood block is coated with sensitized gelatin and the design printed thereon. The picture-forming elements are then cut in the block, shading being produced by hatching, cross hatching or the application of dots. For large surfaces the outlines only may be cut and the unwanted parts scraped away from the resulting negative. The negative is then coated with ink and transferred to a transparent foil of cellon or celluloid. In some cases only those parts requiring a special intensity are reproduced, the negative being then combined with a negative from the original design. For producing colour printing blocks, a set of partial negatives corresponding to the colour of the subject are prepared. Cut-outs or stencils may be formed by printing from the wood block onto thin metal foil, covering the parts not required to be treated with an asphalt lacquer, and etching completely through the foil in the uncovered parts. Such stencils may be used for applying a screen pattern to parts of a photo-mechanical printing surface, or for shading, retouching or colouring a photographic picture. The Specification as open to inspection under Sect. 91 describes also a process in which the cut block is coated with actinic dyestuff, the cuts filled with black material and the whole photographed. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to trucks or bogies for railway vehicles
IPC: B61F5/16
Filed: 1935-05-07
Abstract: 456,349. Railway vehicle bogies. KRUCKENBERG, F., and STEDEFELD, C., 166, Deutz-Mulheimerstrasse, Cologne, Germany. May 7, 1935, No. 13451. Convention date, May 4, 1934. Addition to 399,373. [Class 103 (vi)] The invention described in the parent Specification, in which the bogie of a railway vehicle is connected to the body by means of two longitudinal hinge-bars, is modified in that the bogie has no main centre pivot, while the hinge-bars permit the bogie independent lateral and pivotal movements relative to the body. In the construction shown in Fig. 1, the hinge-bars 11, 12 are pivoted at their outer ends 13, 14 to a cross-member 16 of the bogie frame 15, while their inner ends 17 are pivoted to a double-arm lever 21 hinged at 20 the vehicle body 19. To prevent undesired swivelling or rolling movements of the bogie, one arm of the lever 21 may be extended at 23 and connected by a link 24 to a vibration-damper 26. In a modification, Fig. 2, the bars 11, 12 are located outside the frame 15 to provide greater accommodation between the frame side-members, and the inner ends 17, 18 of the bars are pivoted to hinged bell-crank levers 29, 30, which are connected by a cross-bar 33 associated with a damper 37. This construction may be modified by arranging the pivots 13, 14 on the vehicle body and the bell-cranks on the bogie. Specification 400,822 is referred to.

Title: Improvements in or relating to the manufacture of catalytic masses and their employment in organic reactions
IPC: B01J37/00
Filed: 1930-05-02
Abstract: Catalytic masses are prepared by precipitating the catalytic elements (in the form of oxide, hydroxide, carbonate or other salt) in a highly colloidal or gelatinous form, removing the surplus liquor, forming the precipitate into the desired shape (e.g. by extrusion or tableting), and thereafter drying it completely, the whole process being performed at ordinary temperature or at a temperature not exceeding 30 DEG  C.  After drying is complete, the catalyst may be subjected to a chemical conversion, e.g. of carbonate to oxide, but temperatures exceeding 450 DEG  C. should be avoided in this operation.  If several catalytic elements are present they may be either co-precipitated or mixed after precipitation.  The precipitate may be kneaded in a paint mill or the like before moulding. According to an example zinc nitrate solution, or a solution of zinc and magnesium nitrates is precipitated with soda ash solution, the precipitate is washed by decantation, filtered, kneaded, extruded, and dried at room temperature.  In another example sodium tungstate solution is precipitated by hydrochloric acid and similarly treated. Specification 300,142, [Class 1 (i), Chemical processes &c.], is referred to.

Title: Improvements in or relating to injector burners for autogenous metal working
IPC: F23D14/46
Filed: 1934-05-07
Abstract: 425,727. Blowpipe burners. JAGFELD, J., 17, Litzmannstrasse, Rheydt, Germany. May 7, 1934, No. 13735. [Class 75 (i)] An injector burner more particulary for autogeneous metal working is formed with a mixing chamber for oxygen and fuel gas which chamber communicates with one or more closed hollow spaces in such manner that the mixture acts with a suction effect on the mouths of the hollow spaces. Oxygen and fuel gas pass from pipes 2 and 9 under the control of valves 4 and 11 into pipes 5 and 12 leading respectively to the oxygen nozzle 6 and an annular space 13 from which latter the fuel gas is drawn into the mixing chamber 7. The mixture flows from the chamber 7 by way of a nozzle 17 intc a second mixing chamber 18 drawing with it air from an annular space 15 surrounding the chamber 7 and communicating with the atmosphere by way of apertures 16. A closed annular space 23 surrounds the chamber 18 and the combustible mixture as it passes from the chamber to a pipe leading to the burner tip 21 exerts a suction effect on and continuously evacuates the chamber 23. In a modified form the intermediate mixing chamber and surrounding annular space communicating with the atmosphere are dispensed with. If during operation throttling occurs due to overheating of the burner tip, the throttling acts primarily on the evacuated space 23 and only to a small extent on the mixing chamber 18 so that the injector action and the composition of the combustible mixture remain substantially constant. In addition back firing would be extinguished in the space 23.

IPC: B64C39/00
Filed: 1954-05-11
Abstract: 898,360. Aircraft. AVRO AIRCRAFT Ltd. May 10, 1955 [May 11, 1954], No. 13790/54. Class 4. In an aircraft comprising a generally lentiform structure as described in Specification 898,358, a group of gas turbine engines 37 is positioned between the aerofoil surfaces in a generally radial arrangement with their intakes directed towards the centre of the structure and their outlets directed towards its perimeter. Each engine 37 is attached to a segment 11 and is housed in a cylindrical shell 38 within an annular fuel tank 13 with the aid of mounting means 43; 40, 39. The air intakes of the engines register with openings in an annular plenum chamber between walls 14 and 21, to which air is admitted through ports 29 or through spring closed ports 27, Fig. 8 (not shown), during take-off when the ports 29 are closed to avoid admission of combustion products from the " gas cushion " on which the craft rises. It is stated that, because of this ground cushion effect, the aircraft rises vertically although it may have a weight greater than combined static thrust of all its engines; The gases from the engine outlets, are ejected from the periphery of the aircraft and their flow is controlled to control the aircraft similar to the manner described in Specification 898,359 and as described in Specification 898,362. In " take-off" position a selector handle 80 closes shutters 72 so that all gases are ejected downwardly through an annular nozzle 69, but during flight this handle is moved to allow gases to be ejected from upper and lower nozzles 68, 69, the annular shutters being then eccentrically disposed to close both nozzles at the front and to locate them open to a progressively increasing extent towards the rear. A control handle 79 causesdifferential movement of the shutters so that its movement to port reduces. the proportion of port flowing gases having a downward component and increases the proportion of starboard flowing gases havinga downward component. Rudder pedals 83 control shutters 82 for openings 81 to port and starboard. Specification 892,401 also is referred to.

Filed: 1923-05-25
Abstract: 218,804. BreuillÚ, H. May 25, 1923. Refuse-consuming furnaces.-In a shaft furnace for burning refuse the air for combustion flows down vertical passages in the furnace walls to openings in the combustion zone, the combustion gases escaping through other passages in the walls or through a central tube; water jets for breaking up the slag and preventing it from adhering to the walls are also provided. The air enters through collectors 7, passes down passages 8, where it is heated, and enters the furnace through openings 6. The combustion gases may either be drawn off through openings 11 and a collector 16, in which case they may be used for heating boilers, or, if combustible gases are required they are drawn off through openings 12, passages 18 and collectors 19. Movable slabs 14, 14a allow of the passages being closed to cause the gases to take the required course. Alternatively, both passages may be closed and the gases drawn off through a central tube 44. A further air supply may be introduced by a fan 36 under a cone 39. The slag is cooled and disaggregated by water admitted through jets 20 in the walls and a pipe 37 opening under the cone 39, the steam produced being drawn off through a hollow ring 24. A water jacket 40 prevents the slag from adhering to the walls of the furnace. The cooled slag falls on a rotary plate 27 and is removed by a scraper 31.
