Patent GB-484096-A (GB)
Title: Improvements in processes for preparing kinematograph colour films
IPC: G03C7/22
Filed: 1936-10-29
Abstract: 484,096. Photo - mechanical colourprinting. ARMSTRONG, J. J. V. Oct. 29, 1936, No. 29448. Drawings to Specification. [Class 98 (ii)] In a process for producing subtractive multicolour picture films, intaglio depressions are formed in the surfaces of metallic strips corresponding to colour separation records of the original without the use of any line or other screen, each strip is inked in one of the complementary colours and prints are made from these on a common transparent flexible strip. The originals may be prepared as three separate images, e.g. by means of a camera of split-beam type or on tripack material, or a single film consisting of three layers containing colour record images may be used. The separate images may be printed onto a lightsensitive layer, e.g. of bichromated fish-glue and gelatin or a silver salt emulsion, on a metallic strip, e.g. of burnished copper. Alternatively, the print may be made on carbon tissue and transferred to the copper strip. Where three-layer material having images in colour is used, printing may be effected by coloured lights or the use of filters. To ensure accurate registration in printing, register lines are printed on the receptive surface and on the printing strip for use with a photo-electric cell connected to means for effecting relative adjustment of the surfaces. The printing may be performed on celluloid or cellulose acetate strip in turquoise blue, yellow, and magenta inks.

Title: Portable hand-operated floor polishing machines
IPC: A47L11/08
Filed: 1935-10-26
Abstract: 464,350. Floor waxing and polishing machines. SIMPSON, J. R. Oct. 26, 1935, No. 29580. [Class 138 (i)] A waxing and polishing machine with friction driving wheels is characterized by a container 18, Fig. 2, wherein a piston 19 acting as a nut on a rotatable screw 20 is driven mechanically from the wheels to exude polish. Friction wheels 1, 2, rubber tyred, are mounted on a spindle 3 carrying a loose bevel 5 upon which is mounted a slip clutch 6 operated by a spring 7 to ensure smooth engagement. The bevel engages with a pinion 8, Fig. 1, of a flywheel 9 which is rotated about a spindle 10 and under its momentum upon the inward movement of the operator, The polishing member 11 is detachably connected to the flywheel at equidistant points by spigot elements 12 sliding freely in vertical slots 13 in the rim of the flywheel. Pressure is applied by leaf springs 14 regulated by screws 15. Longitudinal stability is maintained by a roller 16. The rotation of the screw 20 is effected from the reciprocal motion of the handle. Transmission is accomplished by an element 21 pivotally mounted on link members 22, 23. The link 23 is connected by pawl and ratchet with the screw 20. Variation of the motion is effected through the link 22 which is pivotally mounted in the handle and may be moved to give a different throw as required. The screw 20 is held during the idling movement by a leather washer 28, Fig. 2, the polish is fed through a lead 30, Fig. 1, terminating in a flexible rubber 31. In a modification, Fig. 3, the polish feed is rotated by bevel gears 33 driven from a spur wheel 34 engaging with a worm 35 on the hub of the flywheel. Engagement is made through any convenient form of clutch such as a screw and cone 36. Where a variable feed is desirable, the reciprocal mechanism of the feeder shown in Fig. 1 may be combined with the worm drive of the flywheel.

Title: Improvements in or relating to electric irons
IPC: D06F75/30
Filed: 1950-12-04
Abstract: 672,628. Electric irons. BRITISH KAUMAGRAPH TRANSFERS, Ltd. Dec. 4, 1950 [Dec. 24, 1949], No. 29583/50. Class 39(iii) An electric iron for applying heat transfers, e.g. to garments, comprises a sheet of electricallyconducting resistance material 14, e.g. in cloth form, extending under the iron and above the sheet 14, a resilient pad 10 adapted, during ironing, to hold the sheet 14 resiliently in contact with the material to be ironed. The pad 10, e.g. of silicone sponge rubber, is retained in an open box-like holder 9 secured to a rod 8 to which is attached a handle 7. Slidably mounted on the rod 8 is a bushing 11 to which are fixed a ceramic member 12 and a cover 16, metal brackets 18 carrying the sheet 14 being secured to the opposite sides of the member 12. A socket 17 in the cover 16 enables current to be supplied to contacts 13 which are mounted on the member 12 and which contact the brackets 18. A helical spring normally tends to force the bushing 11 and associated parts downwardly whereby the sheet 14 is spaced from the pad 10. When the sheet 14 is placed on the material to be ironed, additional pressure forces the pad 10 into contact with the sheet 14, to facilitate the application of heat transfers to irregular, e.g. grained wood, surfaces.

Abstract: 327,667. Harrison, W. R. Sept. 30, 1929. Pulleys.-Sheet metal pulleys are produced by flanging a blank either by cupping or spinning to the form shown at 62, Fig. 4 and riveting the blank to a hub 64 by which it is centred on a pilot 36 mounted on a driven spindle 19 of a machine for forming the V-groove. The spindle carries a die 22, a counter-die 34 being mounted by a ball bearing on a tailstock spindle 27 fed by an air cylinder 30. A saddle carries a crossslide 17 carrying a roughing roll 39 and a finishing roll 41 brought into action in succession by a double-acting air cylinder 46. A small cylinder 50 always open to pressure returns the cross-slide to mid-position for the removal of the finished pulley.

[Classes 17 (i) and 17 (ii).] A shoe made wholly or mainly of rubber is formed by turning outwardly the unvulcanized rubber edge of the upper and attaching it directly by stamp-welding to an unvulcanized rubber sole. The edge of the upper itself may be out-turned, or an L-shaped edge strip of unvulcanized rubber may be secured to the upper. Preferably, the stamp-welding press includes a knife for cutting the welded edge to shape. A press with a patterned surface may be used to produce a patterned surface on the welt-like edge. After the stamp-welding, the shoe is vulcanized. Apparatus for making the shoe comprises a last 1 on which the upper 4 is stretched, and a flat support 6. The edge of the upper is turned outwardly on to the support and is held in this position by pegs 10. A sole 14 is then placed upon the last. A combined pressing and cutting member 13, 12 is guided by guides 11. The apparatus is placed in a suitable press, so that the knife 12 trims the sole and upper to shape, whilst the presser 13 stamp-welds the edges of the upper and sole. The support 6 is in two hinged parts, to facilitate insertion of the last.

The inertia ellipses are circular or substantially circular, and each of at least some of the blocks has a recess and a substantially straight groove extending from the recess to a groove bounding the block. The grooves are so arranged that liquid dispersed by the tyre when running can flow from the centre of the contact patch to the tread edges obliquely generally obliquely to the circumferential direction of the tyre. The blocks may be square, circular, triangular polygonal, cruciform or star-shape in section, and the tread may comprise blocks of different sections (Fig. 9, not shown). The tyre of Fig. 8 must be rotated in one direction only to permit adequate drainage along grooves 84, 85.
