Filed: 1933-06-26
Abstract: 420,611. Glass manufacture. SCHLESISCHE SPIEGELGLAS-MANUFACTUR C. TIELSCH GES., Altwasser, Waldenburg, Silesia, Germany. June 26, 1933, No. 18155. Convention date, July 2, 1932. [Class 56] Relates to a method of making compound sheet glass in which glass of any desired colour, or physical or chemical properties, is formed into a sheet by rolling and is then rolled on to a foundation sheet of different composition. According to the invention, the foundation sheet is made by rolling molten glass which flows continuously from a tank furnace, but the coloured glass is formed by intermittent rolling, so that compound glass of different qualities can be produced as required in any desired quantity and in any desired order. A pattern may be impressed on the sheets if required. The foundation glass b flows from a tank a between a pair of rollers c, d and is formed into a continuous sheet e. A strip f is also produced by a pair of rollers g, h on to which glass of different composition is poured from a pot or ladle p as and when required. The strip f is deposited on the sheet e, and is rolled into adhesion with it by a pair of rollers i, k. Additional apparatus can be provided if a third sheet is to be rolled on to the doubled sheet. The rolling-apparatus g, h may also be mounted between the wall of the tank a and the rollers c, d, in which case these rollers weld the coloured strips to the foundation sheet in course of formation. Also, either the roller c or the roller i can serve as one of the pair that forms the coloured strip f.

Filed: 1920-07-03
Abstract: 146,435. Pateras Pescara,' Raoul, Marquis of. July 3, 1919, [Convention date]. Propelling.-Screw propellers for flying-macliines of the helicopter type are arranged one above the other, rotating in opposite directions, and are provided with means for varying the pitch of the blades continuously and periodically during their revolution. The two propellers are carried by a common hollow shaft 1, which is in two parts connected by the bevel gearing 11, 12, 13. A central rod 14 is provided with universal joints 16, 17 carrying arms 18, 19 which project through slots in the shaft 1 and carry hall bearings 20, 21. Connecting-rods 22, 23 are hinged to the outer rings of the bearings and to reds 24, 25 sliding in the blade shafts 26, 27. Cables 28, 29 are attached to the rods 24, 25 to vary the angle of the blades. If the rod 14 is set in a position inclined to the vertical, the angle of the blades is varied continuously during their revolution. Sleeves 32, 33, 34 within the shaft 1 are connected together by rods 35, 36, and may be raised or lowered simultaneously by a lever 30 and link 31. The sleeves 33, 34 are provided with ball bearings 37, 38, which are connected by rods 39, 40 to the blade shafts 26, 27. These shafts are threaded so that an axial movement of the shafts results in a simultaneous rotational movement, and the mean pitch of the whole of the blades is thereby varied. Movement of the rod 14 results in a periodic variation of the pitch of the blades, according to which their pitch is increased while passing through 180 degrees and decreased while passing through the other 180 degrees. The resultant axial force exerted by the propeller is thus parallel to, but not in, the axis of rotation. The periodic variation may apply to the whole blade, or to a part only. The propeller may be used for lifting, stabilizing, propelling or braking the machine .

Title: Improvements in or relating to the production of compositions and goods containing rubber or similar material
IPC: C08J3/00
Filed: 1932-06-30
Abstract: A three-phase plastic composition comprising rubber and a plastic or mixture of plastics insoluble in rubber is made by dispersing a quantity of rubber in the plastic or mixture of plastics as the continuous medium, and then dispersing this modified plastic into rubber as the continuous medium.  The term rubber includes gutta percha, balata, synthetic rubber, waste and reclaim.  Examples of plastics insoluble in rubber are casein, albumen, e.g. blood and egg albumen, cellulose derivatives (e.g. cellulose nitrate, acetate, viscose and benzyl cellulose) and synthetic resins (e.g. phenol-formaldehyde, urea or thiourea-formaldehyde, casein-formaldehyde, and glycerol-dicarboxylic acid condensation products).  In making the composition, a continuous mass of plastic is formed on mixing rolls or in an internal mixer, such as is commonly used in the rubber industry, and rubber is then dispersed into the plastic by gradual addition with continuous milling or grinding.  The dispersion so formed is removed from the rolls or mixing machine and is then in a similar manner dispersed into a continuous mass of rubber by gradual addition and milling or grinding.  Examples of three-phase plastics, commencing with the innermost phase, are rubber, casein, gutta percha; rubber, phenol-formaldehyde, rubber. Compounding and vulcanizing ingredients may be added, and different characteristics may be imparted by compounding ingredients in the innermost phase and in the continuous phase. The character of the product may also be modified by including compounding ingredients in the plastic.

Abstract: 516,385. Wireless receiving apparatus. KOLSTER-BRANDES, Ltd., and BEATTY, W. A. June 24, 1938, No. 18796. [Class 40 (v)] [Also in Group XXXVI] A push-button wireless receiver is arranged so that the push-buttons, in addition to altering the wavelength and waveband if necessary, simultaneously alter another feature of the set such as tone, selectivity, obscuring a tuning dial, switching from manual to automatic tuning, or projecting a picture indicative of the station tuned on to a screen. The wave-change switch may be operated by a solenoid device as shown in Fig. 2, the solenoid 10 being energized by a contact controlled by a push-button to step ratchet wheel 17 until a required waveband is selected. The stepping continues until the marked wiper 37, 40 rests on its appropriate insulating segment on disc 29. At the termination of each step of the ratchet, the brush carrier is swung by solenoid 10 in the opposite direction to the movement of the disc 29, and the brushes are arranged to make contact only at the termination of this swing so that the solenoid circuit is not broken during a step. Alternatively the movement of the tuning condensers such as 68, Fig. 4, may be effected by push button 52 'through cam mechanism 48, 56 the condensers being moved until the cam engages pins 58, 59 as indicated in Fig. 6 whilst a similar cam mechanism 74, 79 operated by the same push-button may operate a wave-change switch attached to spindle 85. Other cams may be similarly simultaneously operated to,perform other tuning functions. A mechanism for obscuring the tuning dial when automatic tuning is used is shown in Fig. 7. When automatic tuning is being used a circuit is completed for solenoid 94 so that catch 93 is released and shutter 88 falls to obscure the tuning screen, whilst lever 95 operates togglesswitch 96 to switch over the circuits from solenoid 94 to solenoid 92. When manual operation is required, operation, of a wavechange button or manual tuning-button energises solenoid 92 so that the shutter 88 is raised and is held in its upper position by catch 93, the shutter 88 operating switch 96 to open the circuit of solenoid 92 and to prepare that of solenoid 94.
