Title: Improvements in or relating to rubber soles and heels
IPC: B29D35/12
Filed: 1923-12-07
Abstract: 226,030. Gaisman, L. Dec. 7, 1923. Moulding indiarubber and boots and shoes.- Concavo-convex rubber heels and soles are formed by inserting a partially-vulcanized flat blank a, Fig. 2, into a ring or frame mould b, Fig. 7, of similar contour but smaller dimensions than the blank, causing the blank to arch. and completing the vulcanization therein. The moulds b are preferably of sufficient depth to permit of stacking in the vulcanizer. A block c, fitting the frame b and formed with a convex top, may be employed to facilitate positioning of the blank a. Any desired pattern or holes for washers, screws &c. are imparted to the flat blank during the partial vulcanization.

Title: Improvements in or relating to variable ratio movement transmission mechanism
IPC: F16H19/00
Filed: 1952-12-04
Abstract: 758,636. Toothed gearing. AIR SERVICE TRAINING, Ltd., and WOODHAMS, R. J. B. Dec. 4, 1953 [Dec. 4, 1952], No. 30776/52. Class 80(1) [Also in Group XXXIII] A variable ratio linear movement is transmitted from a rod 1 to a rod 5 through rack and pinion gearing. Parallel racks 2, 4 which are coupled to the rods 1, 5 respectively are guided for movement in a casing 52 and engage at diametrically opposite points with a pinion 3. The pinion 3 is rotatably supported on a carrier member 7 which is also guided for movement parallel to the racks 2, 4. The pinion carrier 7 is coupled by trunnions 10 to a lever 8 which is adapted to be oscillated by the rack 2 by pivot connection 11 therewith about an adjustable axle 9. The axle 9 is carried on a block 24 which is engaged by a screw shaft 23 rotatably supported in the casing 52 and adapted to be driven through chain and sprocket and bevel gearing (not shown) from a suitable point. If the axle 9 is adjusted to coincide with the trunnions 10 no movement is imparted to the pinion carrier 7 on movement of rod 1 and the rod 5 will move an equal amount to rod 1 but in the opposite direction. If the axle 9 is adjusted so that its distance from trunnions 10 is the same as the distance between trunnions 10 and pivot 11 then the pinion carrier 7 will move half the movement of rack 2 and no movement will be imparted to rack 4 and rod 5. Intermediate positions of axle 9 will give intermediate degrees of movement of rack 4 and rod 5. The mechanism is applicable to an aircraft control for actuating the valve controlling the power operation of a control surface. The adjustment may be effected manually or automatically in accordance with the flying conditions such as speed and altitude.

Title: Improvements in or relating to television transmitting tubes
IPC: H01J31/26
Filed: 1938-10-27
Abstract: 520,646. Television transmission tubes. BLUMLEIN, A. D. Oct. 27, 1938, No. 31063. [Classes 39 (i) and 40 (iii)] In a television transmission tube 1 wherein an optical image is focused on a photo-electric cathode 4, the composite electron stream derived therefrom charges negatively the mosaic elements 14 on a mica screen 12 ; this is scanned on its back by a light spot to return the elements to a positive datum ; the photo emission from the elements to a collecting grid 11 being limited by a control grid 13 placed on or closely adjacent to the screen and by the mosaic elements. Secondary emission grids 5-10 may be 'interposed between the photocathode 4 and grid 11, these being spaced as described in Specification 515,264. The light spot may be obtained from a cathode ray tube 18 with luminescent screen 19 ; focusing means 20 are used. Metal shields 20a prevent interference between the tube 1 and a cathode ray tube 18. The grids 5-11 have small aperture ratio to prevent the scanning light spot from acting on the cathode 4; or the grids may be formed of conductors in parallel planes but inclined to each other. The grid 13 may be formed as set out in Specification 490,537 ; it may be gold plated so as not to be photo sensitive and used as the signal plate instead of the translucent coating 15. The control grid is maintained at substantially the potential of the cathode 4 or where multiplying grids are used at the potential of the final grid 10, Fig. 2, or slightly negative to this potential; the electrode 11 carries the highest positive potential. Electrons from the cathode 4 or secondaries from the grid 10-where this is used-will not be taken up by the grid 13. The return to datum potential by. emission due to the light spot is not instantaneous this time lag being compensated for in the amplifiers. Sudden increases in light on the photo cathode 4 may be compensated for by taking signals off the grid 10 to be mixed with picture signal taken from the resistance 27 ; or the beam in the tube 18 may be modulated to give a varying light spot for scanning. In a modification two grids 31, 32, Fig. 3, are interposed between the grids 10 and 11 the latter now being secondary emitting and at the same potential as the grid 31; grid 32 is now at highest positive bias ; the control grid 13 and coating 15 are connected but the coating may be omitted. The grid 32 is connected to the signal resistance. Emission from the mosaic elements is multiplied at the grid 11. Specification 457,493 also is referred to.

Abstract: 520,782. Wireless receiving systems. BELLING & LEE, Ltd., and STRAFFORD, F. R. W. Oct. 27, 1938, No. 31086. [Class 40 (v)] Interference from locally-produced electrical discharges is prevented by providing parallel to the downlead 2 of an aerial 1 a second conductor 6, the conductors 2, 6 being respectively connected to the high and low potential input points 4, 8 of a receiver through two mutuallycoupled inductances 3, 7 which when connected in series through the input impedance of the receiver present a path of low reactive impedance. The inductances 3, 7 have a magnitude considerably greater than that of the input impedance of the receiver. A variable condenser capacity 9 is preferably connected across the inductance 7 in order to balance out the effect of the collector 1 and obtain a symmetrical input to the conductors 2, 6. In order to obtain high mutual coupling between the coils 3, 7, these are wound on a slotted former with interposed sections. If reception is desired over a wide frequency band a plurality of pairs of inductances may be used each pair functioning over a particular range of frequencies. Specification 468,763 is referred to.
