Abstract: 488,479. Copying milling-machines. DECKEL, F. (Deckel Prazisionsmechanik und Maschinenbau, F.) Feb. 3, 1938, No. 3427. Convention date, Feb. 5, 1937. [Class 83 (iii)] In a copying milling-machine, having a movable tracer, mechanical means are provided for indicating the deflections of the tracer caused by its engagement with the pattern. The vertical slide 2 carries horizontal slides 3, 4, the latter carrying the cutter-head 6 and tracer-head 5. Part of the cutter-head may be connected at 11 to perpendicular slides 9, 10 which may be operated by hand wheels 12, 13 to move the cutter and tracer slide 4 to a horizontal plane, the slide 4 being also free to move in a vertical plane. The tracer pin is mounted in a sleeve 22 having a spherical universal mounting in the holder 24. The upper end of the sleeve is normally centred by spring pins 29. A multiplying lever 31 having a spherical bearing at 32 engages the upper end of the sleeve so that when the tracer is deflected the lever end 33 moves over a plain glass or other transparent screen 34 which is divided into concentric zones by circles 36a-36c. Thus both the direction and magnitude of the lateral tracer deflection are indicated. In order to leave the work oversize after preliminary milling, the wheels 12 and 13 are operated to move the cutter and tracer, and the latter is arranged so that when it is deflected into the shaded zone, Fig. 4, the work is the required size for subsequent finishing. In a modification, Fig. 5, particularly for horizontal surfaces, the housing 24a of the sleeve 22 may move axially against a spring 40 on contact of the tracer with the pattern when the finished shape is nearly reached. This movement acts through a pin 41 on one arm of a multiplying lever 44, the upper end of which moves over a divided strip on the plate 34 to give a visual indication of the axial tracer deflection.

Title: Improvements in or relating to pneumatic tyres
IPC: B29D30/00
Filed: 1933-02-07
Abstract: Tyre covers are made by first impregnating under fluid pressure, e.g. as described in Specification 344,414, [Group IX], unwoven textile fibres, felt, yarns, threads, cords, or the like with a rubber content substantially equal to the fibre content, assembling the impregnated fibres &c. (or fabric laid or woven therefrom) into a tyre casing, treating the casing with a further rubber dispersion (as, e.g. described in Specification 411,460), and then applying the tread portion of the tyre.  The impregnation may consist of an aqueous dispersion of undepolymerized rubber, vulcanized latex, an artificial dispersion from coagulated or regenerated rubber, or synthetic rubber, with or without vulcanizing or emulsified materials.  Before impregnation, the textile material may be treated to set up the same pH as that of the impregnation, and the impregnated material may be subjected to treatment in a humid atmosphere containing vapours of an anti-coagulating agent.  The coalescence of the impregnated material with the subsequent rubber dispersion may be assisted as described in Specification 405,311, [Group V].  The impregnated textile plies of the casing may be united by pre-formed sheets of rubber.  Before the application of the tread rubber, the built-up casing may be immersed in an aqueous dispersion of undepolymerized rubber containing anti-coagulating agents.
