Title: Improvements in or relating to the manufacture of boots, shoes, gaiters and other articles of rubber or rubbered fabric
IPC: A43B3/02
Filed: 1921-01-10
Abstract: 157,792. Chandeysson, U. April 23, 1917, [Convention date]. Drawings to Specification. Leggings and gaiters. - Used or unused pneumatic tyre covers are utilizel in the manufacture of boots &c., gaiters, belts, and the like, the final material obtained being either a number of layers of fabric embedded in rubber, or the fabrics stripped of rubber and reunited by other adhesives. Two methods of treating the tyres are described. According to the first, petroleum is placed into the interior of the tyre and allowed to stand 12-24 hours, when the layers of fabric between which the rubber has been softened are removed by hand. This may be repeated until only a few layers remain. The layers of fabric thus removed are freed from adhering rubber with a skiving knife and are stuck together with dextrin or the like, and cut into insoles, uppers &c. From the remainder of the cover, the tread is cut or ground away leaving a few layers of fabric embedded in rubber. This is passed over a hot iron and smoothed and cut into soles, heels, &c. According to the second method, the tyre is cut and about 15-20 cm. of one end is immersed in petroleum, petrol, or the like and the inner layers of fabric loosened as before. The beads are removed, and the tyre is fastened tread downwards on a bench. The loosened ends are attached to a cylinder running on the bench, and this is rotated over the tyre, separating the inner layers and rolling them on itself. The two portions are then used as above described. The operation is carried out more rapidly if petrol &c. replaces petroleum, but in this case the inner layers have to be soaked in petroleum to disintegrate the rubber between them.

Abstract: 1,248,343. Interference filter. PERKINELMER CORP. Jan. 16, 1969 [Jan. 26, 1968], No. 2597/69. Heading G2J. An interference filter 11 comprises a pair of reflectors 12, 13, for reflecting light over a preselected wavelength, each supported by a respective end of a glass substrate 14, 15 and a further glass body 16 located between the reflectors and having a thickness defining the separation between the reflectors necessary for transmitting light over a pre-selected wavelength. The reflectors 12, 13 are each preferably nine alternate quarter wavelength layers of thorium oxyfluoride and zinc sulphide coated on to the separate ends of fused silica substrates 14, 15, the ends of which substrates are optically flat and plane parallel. In assembly the spacer substrate 16, also of fused silica and having optically flat ends, has one of its ends optically contacted with reflector 13. The substrate 15, reflector 13, spacer 16 combination is then tested at the desired wavelength, by silvering the free end of spacer 16 to determine whether the spacer 16 is of desired thickness to give the required separation. The silvering is removed and a coating 17 e. g. silicon dioxide, is built up to give this desired spacing distance, the reflector 12 then being optically contacted with coating 17. A supplementary coating 18 e.g. of alternate layers of zinc sulphide and cryolite, may be deposited on free end of substrate 14 to remove unwanted sidebands. For use in the infrared the glass may be germanium.

Abstract: 714,324. Change-speed epicyclic gear. BORGWARNER CORPORATION. Feb. 1, 1950 [Feb. 2, 1949], No. 2609/50. Class 80 (2) A three-speeds and reverse planet gear, the driving shaft 12 of which is driven from an engine shaft 10 through a fluid torque-converter 13 of the overrun reactor type which is effective in all ratios comprises two friction clutches 17, 18, both of which are engaged, together for highspeed solid drive, whilst one of the clutches is always employed together with one of two reaction 'brakes 15, 16 for low. intermediate and reverse speeds. The gear comprises first and second trains having suns 29, 33 respectively, both fast on an intermediate shaft 40, the ring- gear 28 of the first being connected permanently to the output shaft 11 through the planet-carrier 35 of the second. For low speed the clutch 18 is applied to drive the intermediate shaft 40 and also the brake 15 is applied to the reaction ring 32 of the second train which then drives alone; for second the brake 15 remains on whilst the clutch 18 is replaced by 17 to transfer the drive from the intermediate shaft 40 to the carrier 31 of the first train, so that the two trains compound; for reverse the clutch 18 is applied, together with the brake 16, to hold the planetcarrier 31 of the first, train, which drives alone from the intermediate shaft 40. Hydrostatic friction clutches and brakes are used, the clutches 17, 16 being each engaged by a piston 41 which acts on the presser-plate 43 through a self-disengaging diaphragm spring 42, with a mechanical advantage permitting the use of a piston 41 of smaller diameter than that of the presser-plate 43, thus reducing liquid centrifugal pressure and hence the required spring disengaging load. Fig. 3, not shown, uses conventional spring-retracted pistons and interchanges the inner and outer members of the second clutch 17 so that the, brake 16 can now act directly on the outer driven member. Specifications 674,525 and 714,408 are referred to.
