According to the method of the invention for removing at least one layer of reinforcing elements (4), such as steel cords, etc. from a breaker or belt (6) located between the tread area (3) and the carcass (5) of a rubber tyre; the tread area of the tyre is first removed down to the layer of reinforcing elements by rasping off this tread area, and afterwards each reinforcing element (4), for examp...

The invention is concerned with a feeler unit for positioning sheet glass processing tools, which comprises a frame carrying at least one feeler roller piloting a tool holder head positioning motor, and a back-up roller engageable with the underside of a sheet glass edge being processed and rotatable about an axis which extends substantially parallel to the plane containing the glass sheet and sub...

A cellular foam particularly suitable for use as thermal or accoustic insulation is produced by the condensation in an acidic medium in the presence of a catalyst hardener of methyloldihydroxydiphenylmethylene ether isomers.

1. Use of a surface area reduced silica gel of a mean grain size of about 0.5 to 50 mu m, which has been prepared in that a conventional silica gel of approximately the same grain size with a larger specific surface is thermally treated by a roasting process between 500 and 1,200 degrees C and/or chemical-catalytically treated with an acid, as a filler for dental materials based on polymerizable m...

3-[(Z)-1-Propen-1-yl]-7-acylamido cephalosporins in which the 7-acyl group is phenylglycyl or substituted phenylglycyl are orally active antibiotics against Gram+ and Gram- bacteria.

An underwater concreting cement composition comprising a base prepared by adding (a) 0.2 to 2.0 parts by weight of hydroxyethylcellulose and (b) 0.01 to 0.2 part by weight of high-molecular weight polyethylene oxide and/or 0.2 to 4.0 parts by weight of calcium formate. The hydroxyethylcellulose preferably has the molar number of ethylene oxide substituted per glucose unit of 1.5 to 4.0 and a visco...

A method for producing asbestos-free cement boards, such as by a scoop-sieving process to obtain inorganic hardening compositions for curing utilises a cement slurry which includes fibrillated wood pulp having specified characteristics optionally unbeaten virgin pulp and if necessary, filler and reinforcing fibers for obtaining 4 to 15 wt. % of the total solid in concentration and below 5 cm<4>/se...

An apparatus for installing reinforcing bottom cups on blow molded plastic containers includes a transfer arm which grasps the outer peripheries of a plurality of molded hollow containers, such as bottles, by suction means, transfers the thus held bottles to a first station at which previously adhesively coated bottom cups are pushed upwardly on to the bottoms of the containers, from which station...

PURPOSE:To eliminate the acoustic connection for a multiple mode filter by distributing plural inter-digital transducer electrodes on a board and setting a prescribed relation among the lengths of electrode fingers. CONSTITUTION:Two SAW resonators 2 and 3 are set in parallel and approximately to each other on a piezoelectric board 1. In order to eliminate an acoustic connection, the vibrating regi...

A seat has a seat element and backrest mounted on a seat frame (4) that is part of a stand, which is equipped with a scissor mechanism and suspension device. The suspension device can be adjusted by means of a setting device (24) in order to change the suspension characteristics of the chair. Both the suspension device and the setting device (24) are situated in the seat frame. Two of the springs ...

The automobile driver's chair has a seat and a back bolt fitted on a frame, the upper part of which is tippable on a lower part, tipping taking place around a transverse axis line. The upper frame part is connected to a lower structure in the lower frame part via front and rear links on each side of the chair. On the front links, the articulated point in the upper frame part is fitted lower than t...

For generating multicolor three-dimensional images a television camera (11) having interlace circuitry (23) and apparatus (14, 20) for directing to said camera light, from a subject (12) are provided, said light reaching first and second mutually spaced sites. Shutter means (15, 21) alternately interrupt the light from the sites at the frequency of the interlace circuitry, so that the output from ...
