Plate blocks are clamped by pneumatically inflatable multilayer elements.

This invention relates to a pneumatic tire (2) with puncture sealing properties and a method for manufacturing such a tire. In this method of manufacturing such a self-sealing pneumatic rubber tire a polymer composition layer (7) is built into the tire in a relatively conventional manner. Under the conditions of heat and pressure used to cure the tire this polymer composition is both crosslinked a...

A tire building drum is described as having, a plurality of radially movable bead lock segments at each end of the drum for holding the tire bead rings during the turn-up operation, a pair of turn-up bladders, and a pair of carriers which work in conjunction with the bead lock segments and turn-up bladders to tension the ply endings of the unvulcanized carcass ply or plies as the ply endings are t...

1527167 Data storage TELEFONAKTIEBOLAGET LM ERICSSON 24 Sept 1976 [29 Sept 1975] 39859/76 Heading G4A The clocking of data through a series of registers is checked by monitoring the propagation of a marker bit through a chain of bistables, one bistable for each register, the absence of one or more clock signals preventing the marker bit from propagating through the chain. The bistables may be spar...

Tire casings are retreaded with precured tread strips in a heated pressure vessel provided with pressure connections which effect simultaneous inflation of the tires and pressurization of the vessel while maintaining tire pressure above vessel pressure. Subsequently a pressure relief system permits the tires to exhaust faster than the vessel. Each tire is prepared for retreading by applying a bond...

A rotary drum air separation system separates mixed solid materials into a light fraction and a heavy fraction with substantially no stagnation of material in the air drum. It further provides for processing high volume urban solid waste without first size reducing the waste. The system separates such waste into a light fraction, substantially free of glass and ready for composting or for use as a...
