(52) The drum includes an independently operable pair of annular pistons (79, 100) associated respectively with the shoulder forming means and the bead seating means such that the shoulder forming means can be operated independently in time, in radial extent and in force app...

An expandable composition of a solid synthetic vulcanizable elastomer of ethylene/higher alpha-olefin/nonconjugated diene copolymer or polychloroprene, a blowing agent, and a curing agent for the elastomer, said composition containing from about 5-25% based on the weight of total polymer of an ionomer resin which is an ethylene polymer containing at least about 50 mole percent ethylene and bearing...

A method and device for fine profiling or shaping tools coated with super-hard material, for example cubic crystalline boron nitride or diamond, especially tools coated with a single layer and having a prescribed or predetermined profile or shape. The rotatably driven tool is profiled or shaped in the region of the cutting surface by a clustered electron or laser beam which is controlled in a cour...

A sealant composition particularly suitable for vehicle tyres comprises a curable butyl rubber and one or more tackifiers, the tensile strength, elongation and cross-link density of the composition being adjusted to produce the necessary properties for tyre sealants. The composition may also be adapted for use in adhesive products for use in connection with membrane roofing materials. The composit...

A down-hole signal transmitter for a mud pulse telemetry system comprises a flow constrictor defining a throttle orifice for the mud flow, a throttling member displaceable to vary the throughflow cross-section of the throttle orifice, and a pump for displacing the throttling member against the mud flow in order to modulate the mud flow. The displacement of the throttling member is controlled by a ...

Rubber powders comprising unvulcanized rubber particles with an anti-tack agent covering are disclosed. These powders are made directly from rubber and anti-tack agent mixtures by mechanical action at a temperature above the glass transition temperature of the rubber. Typical rubbers used include NR, SBR, EPDM, BR and blends thereof and typical anti-tack agents include carbon black, silica and the...

The hydrotreatment of hydrocarbons in the liquid phase is effected in a column containing a catalyst bed supported by a grid, wherethrough passes an ascending stream of the charge admixed with hydrogen which expands the catalyst bed, the perforations of the grid being small enough to prevent passage of the catalyst particles but large enough to permit passage of the hydrogen-charge mixture, the re...

PURPOSE:To enable the improvement in working efficiency by common use of one tablet for inputting of characters and indication of correcting parts. CONSTITUTION:A frame body 7 is formed freely attachably and detachably to and from a table 3 and permits changing of a character sheet 6 according to need. A function key region 6A including the function keys necessary for inputting characters, a ''pro...
