Title: Tread strip for vehicle tyres
IPC: B29D30/58
Filed: 1964-09-22
Abstract: 1,085,802. Vehicle tyres. W. SCHELKMANN. Sept. 22, 1964, No. 13580/67. Divided out of 1,085,801. Heading B7C. A prevulcanized, transversely-curved tread strip the inner surface of which has in transverse section a radius of curvature greater than that of the carcass surface to which it is to be bonded (see Fig. 1, not shown), (a) is provided with means facilitating extrusion of air, during tread application, between it and the carcass and/or (b) has its central and lateral portions of different extensibility whereby on application the strip conforms to the carcass surface. In one embodiment recesses 33 tapering towards the strip edges and optionally communicating with the strip outer surface by holes 41 are closed by a complementary stitching roller (38) (Fig. 5, not shown) and thereby assist both extrusion of air sideways and conforming of the strip to the carcass. In a modification folds formed in the tread grooves are flattened by the roller (38). Through-holes (27) (Fig. 1, not shown) may be formed in the tread grooves. In a further embodiment (Fig. 7, not shown) incisions (36) made below the ribs open during application so as to lengthen the strip central portion, the recesses so formed being filled with the material used for bonding together the strip and carcass. The tread may be formed of two or more annular components which interengage or are joined by pins (51) or a ring (55) (Figs. 9-14, not shown).

Abstract: 1486862 Classifying particles according to their sphericity VACU-BLAST Ltd 31 March 1976 [3 April 1975] 13734/75 Heading B2H Particles are classified according to their sphericity by placing them on a moving surface which slopes in a direction transverse to the direction of movement of the surface so that the particles move down the slope at rates dependent on the sphericity of individual particles. In the embodiment shown in Fig. 1, the particles are fed from a head 11 onto the surface of a conveyor belt 1 which passes around a roller 4 tilted at an angle 5 relative to the horizontal. The belt is either vibrated as shown by the arrow 16 or advanced intermittently. Spherical and near-spherical particles are collected in hopper 10. and grossly non-spherical particles in a hopper 8. In the embodiment shown in Fig. 3 the particles are fed onto the surface of a rotating disc 30, the said surface being in the form of a shallow cone. Spherical and near-spherical particles are collected in receptacles 35 and particles which are still on the disc after slightly less than one revolution are removed therefrom by a jet of air from a pipe 36 and areblown into a receptacle 37. The disc is rotated intermittently or is vibrated in either a circumferential or rectilinear horizontal direction. The disc may be made of. aluminium- or of plastics material coated with metal. A plurality of discs may be arranged above one another on a common axis. The feed head 11 is constructed so that particles only flow through the head from a hopper 12 when the head is vibrated by means 29.

Patent GB-139771-A (GB)
Abstract: 139,771. Maschinenfabrik Augsburg- Nurnberg Akt.-Ges. Oct. 17, 1917, [Convention date]. Gyroscopic apparatus.-A gyroscopic turn-indicator for aircraft &c. comprises a gyro 1 mounted in a ring 3 which is pivoted at 4 within a casing 5 secured to the aircraft. Precession of the ring 3 due to turning of the aircraft moves a pointer 7 over scales 8 to indicate the rate of turning; springs 6 control the precession. Pendulums 9, 12 are provided to indicate the apparent vertical. In a modification, the scale over which the pendulum swings is connected, either directly or through gearing, to the ring 3 so as to be displaced when the ring precesses, and the gearing may be so adjusted that the pendulum indicates the inclination of the aircraft &c. to the true vertical. Means may be provided in connexion with the pendulum and scale for maintaining the aircraft &c. at any desired inclination. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the construction shown in Fig. 4 (Cancelled). in which the gyro 32 is mounted in a frame 30 pivoted in a frame 29. The frame 30 carries an arm 34 operating a lever 35 connected to the pointer 37 by a resilient member 36. Movement of the pointer is restrained by springs 39.

Abstract: 514,738. Thermionic cathodes. DODDS, J. M., LUDLOW, J. H., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. May 13, 1938, No. 14375. [Class 39 (i)] In a push-pull back-to-back multigrid valve, wherein two anodes and respective grids are associated with a common central cathode as described in Specifications 458,702 and 497,359, the cathode is divided into two portions with a metal screen between them which is connected to the cathode and preferably at half the cathode potential. The electron stream on one side of the cathode is thereby shielded from the controlling fields on the other side. The double cathode structure consists of a continuous wire filament 27, Figs. 1, 2 and 3, supported by tubes 2 and 7 through which cooling fluid may flow, and by saddle members 16. The saddle members are carried from a channel shaped member 11 by wires 15 with re-entrant hook springs 14 which tension the filament segments. The lower ends of the filament pass through staggered holes 22 and 24 in the bar members 21 and 23 which are soldered respectively to the tubes 2 and 7. The metal screen 17 is inserted between the two planes of parallel wires formed, and is soldered to the arms of tube 7. In another form, Figs. 6 and 7, the metal screen 33 is soldered to the side arms of tube 2 and the filament consists of a plurality of hairpin-shaped strands 38, one leg of which is disposed on each side of the screen 33 and the ends clamped against transverse bars 29 and 30 behind the strips 39. The bight portions of the strands are accommodated in a plurality of grooves 37 in a saddle member 36 which, for tensioning the filament, carries plungers 35 fitted-with compression springs 34-into holes drilled into the metal screen 33. In a modification of the last form, the filament structure is inverted. A single wire filament may also be used in this form by employing a system of pegs on the plates 29 and 30. In a further modification, a cathode structure as described in Specification 497,362 may be used, being duplicated ; the screen is carried by and between the frameworks. The vacuum seal shown in Figs. 1 and 2 consists of a plate 6 covering the aperture 3 in plate 1 with insulation by a mica washer 13 and insulating compound filling the space.
