The present invention is concerned with the problem of preventing dust-formation on electrode plates of lead. The problem is solved by applying a coating of water-insoluble plastics material on the surface or surfaces of the electrode plate. Examples of suitable materials are polyacrylates, polystyrene, polyvinylacetate and polyvinylchloride. Copolymers may also be used.

An apparatus for vulcanizing pneumatic vehicle tires where the tire beads, in the mounted state, are disposed on the radially inner periphery of a rim next to the essentially radially inwardly extending rim flanges. In order to obtain tires having a long service life and tire beads with a good sealing quality, it is proposed that the tire be vulcanized in essentially the proper contour for operati...

1473598 Ammonium polyphosphates HOECHST AG 27 Nov 1974 [30 Nov 1973] 51377/74 Heading C1A [Also in Division C3] An ammonium polyphosphate having the general formula in which n is a whole number of more than 400 up to 1000, and the ratio of m : n is substantially 1 : 1 may be prepared by heating substantially equimolecular proportions of ammonium orthophosphate and phosphorus pentoxide at 170-350‹C...

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...

The invention relates to a method of manufacturing supports for porous filters. Supports are placed in contact with a first slip coating liquid containing in suspension a mineral powder comprising agglomerates between 10 and 30 microns in diameter, the resulting deposited layer is dried by heating it to approximately 100 DEG C., the layer is brushed so as to remove particles of powder which have ...

The apparatus is composed of two coaxial crucibles (3, 4) the outer one (4) presenting a low-softening temperature, so that it might be drawn with the raw materials. Thus a fibre is obtained with an outer coating which protects it against atmospheric agents. According to this process raw materials are used allowing the fabrication of fibres which may be used to transmit optical radiations with wav...
