Title: Process for producing a web of flexible material formed with at least one inflatable chamber, process for producing a packer and a packer
Inventor: VOEGERL JOHANNES
IPC: B29C65/00
Filed: 1989-01-20
Abstract: For producing a web of flexible material formed with at least one inflatable chamber, a layer of a material vulcanisable at a higher temperature is arranged on a layer of a material vulcanisable at low temperature to form an intermediate structure, the intermediate structure is heated at the lower temperature, the intermediate structure is subsequently arranged between two wider webs or sheets of vulcanisable material and the arrangement comprising the sheets or webs with the intermediate structure arranged in between is vulcanised at the higher temperature. After the heating, the intermediate structure has one side which during vulcanising bonds to the web or sheet of vulcanisable material, while the other layer of the intermediate structure does not enter into any bond with the opposing rubber web. This material can be used to produce packers by pieces being cut off from an endless web and interconnected at the ends. After arranging valves on the annularly joined-together piece of an endless material web, the chambers which are formed in the material web can be inflated, so that the function of a packer or pipeline sealing cushion can be performed. <IMAGE>

Title: Apparatus for draining sewage-collecting tanks in residential areas
Inventor: NEDDENS HERBERT
IPC: E03F5/00
Filed: 1989-01-23
Abstract: The invention relates to an apparatus for draining sewage-collecting tanks in residential areas, comprising a collecting pipeline from which branch lines lead to valves, which are arranged in the sewage-collecting tanks and lead to a pumping and/or intake station.

Inventor: BAYER HEINER DR RER NAT
IPC: H01L21/58
Filed: 1989-07-12
Abstract: Proposed for the assembly of semiconductor chips (31, 32...36) is an acrylate-based adhesive which can be cured rapidly by UV light and which gives an adhesive bond that is resistant to welding but can be readily removed with solvents after welding.

Abstract: Used tyres, and partic. very large sizes, are disintegrated by mounting each tyre on its i.d. so that it can turn, cutting a large slot radially out of its o.d. by its sidewalls and radially further out than its i.d.; the tyre is then turned through 180 deg. and a similar large slot is again cut  out; a number of such pairs of slots are made until only loose rings remain. The tyre (19) is held by an overhead system (28) so that the tyre rests on rollers (30) on one or both sides by the rim; the tyre is lifted by the system and taken to the cutting station between two serrated cutters. The tyre is positioned so that its inner dia. (31) remains just above the holder as shown. ADVANTAGE - The method is the first to disintegrate large size tyres economically. It uses simple and inexpensive equipment.
