IPC: C08J5/06
Filed: 1943-04-28
Abstract: 577,985. Coated fabrics. DUNLOP RUBBER CO., Ltd., and ILLINGWORTH, J. W. April 28, 1943, No. 6688. [Class 140] A continuous process for the production of rubberised fabric for use in tyres, belting &c. comprises treating a ply of textile material with an aqueous preparation of an adhesive for rubber passing the treated material through an atmosphere of dry steam, and calendering a layer of unvulcanised rubber composition on to the soconditioned textile material. The textile material may be cotton or rayon in the form of a woven fabric, a sheet of parallel cords, or a woven cord consisting of parallel warp cords with a few weak weft threads. The adhesive may be an aqueous solution or dispersion of resin forming substances e.g., a phenol such as resorcinol and an aldehyde such as formaldehyde in aqueous solution in admixture with rubber latex, or an aqueous dispersion of rubber containing a protein such as casein, and carbon black. The rubber composition may be based on a mixture of raw and reclaimed rubber with or without a copolymer of butadiene and styrene, and may be compounded with sulphur, zinc oxide, accelerators such as mercaptobenzthiazole, softening agents such as pine tar, stearic acid, coumarone resin, or bitumen residues, and rubber-reinforcing agents such as carbon black and calcium carbonate. The web of textile material, after passing through a dilute - aqueous solution of the adhesive, is advanced upwards into a chamber through which steam heated to 140‹C. is passing at atmospheric pressure, then over rolls heated to 110‹C., and finally between calender rolls where the rubber composition is applied. Steam under pressure may be used. Specification 577,982, [Group IV], is referred to.

Title: Improvements in tapping attachments for drill presses and other machines
IPC: B23Q11/04
Filed: 1919-03-20
Abstract: 139,628. Pawson, G. March 20, 1919. Attachments for tapping.-A tap reversing-drive, of the kind in which a spindle is formed in two parts having relative longitudinal motion so that a clutch member on one part is adapted to engage alternately with a diractly-driven clutch part and a reversibly-driven clutch part, has a yielding device .between two plates in the drive, so that a definite torque cannot be exceeded. The top spindle k has a dog-clutch o adapted to engage alternately a directly-driven clutch portion l on a pinion e and a reversiblydriven clutch portion m on a pinion f<2> driven in reverse rotation through gearing from the pinion e. This pinion is fixed to a sleeve d which also carries a driven plate c rotated from the spindle a and driving plate b through spring levers p, rollers p<1> on which engage inclined faces s' of projection s on the plate. Should the resistance increase beyond an amount regulated by the springs q, the rollers p are forced down the faces s' until they are free of the projections on the plate, and so the rotation of the tap ceases. To ensure a positive drive of the tap during withdrawal, a flanged plate w on the driven plate allows limited axial motion of the spindle a and plate b, so that a stop v on the lever is free during forward motion but engages the rim of the driven plate during withdrawal to prevent rocking of that lever to disengage the drive.
