The tendency to blocking of polymer sheets can be reduced by means of anti-blocking agents. Suitable anti-blocking agents in transparent polyvinyl butyral sheets are especially montanic acid esters, which do not adversely affect the adhesion of the sheet to glass. The polyvinyl butyral sheets are used as interlayers of laminated glass (safety glass).

A tire for two-wheel vehicle comprising a casing formed of a crown with a tread and two sidewalls each terminating in a bead intended to rest on a tire rim and an inner tube glued in manually removable manner to the inner wall of the casing in the region of the crown is improved due to the fact that the inner tube is glued under circumferential tension to the casing so that its inside equatorial r...

An auxiliary controlled valve including a valve body (8) displaceable against a valve seat (9) disposed in a drilling string (6) to produce pressure pulses in drilling fluid renders possible a selective closing or opening of a low-resistance transmission section (12) which lies parallel to a main throttle section (10). The valve has a central passage which permits the passage of measuring instrume...

Method and apparatus for producing a fabric from a fibrous web comprising at least 5 percent thermoplastic fibers, said method comprising superimposing the web on a first carrier belt, superimposing a second carrier belt on the web, causing the web and belts to travel about at least two heated rolls, and cooling the web between the belts.

Deep aeration of sewage is carried out by pumping sewage from the vicinity of the surface of the tank to groups of nozzles (3) where it is mixed with air and then is ejected in the vicinity of the bottom of the tank. The passing of the sewage from the nozzles (3) draws in the air to be mixed therewith before ejection of the mixture from a collector (4) containing the groups of nozzles.

A header assembly comprising a thermoplastic housing and two rows of metallic conductor pins is attached to a printed circuit board. The conductor pins have tails which are bent over anvil portions of the housing and project through slots in a locator plate at the conductor end of the housing. The locator plate slots have detents for retaining the bent tails in a pattern to facilitate assembly and...
