Title: Flexible floor covering for aircraft
Inventor: KRAL HANS-PETER
IPC: D06N7/00
Filed: 1991-02-21
Abstract: A flexible self-adhesive floor covering, and one partic.  for aircraft, is produced with a flexible sheet of  flame-resistant type of polysiloxane. The underside of this polymer is bonded to a flexible non-toxic material which is difficult to burn and which produces little fumes, and a self-adhesive covering is applied to the underside of this. The  flexible material is pref. made from phenol/aldehyde fibres and is bonded to the polysiloxane with an adhesive based also on polysiloxane but other suitable adhesives include acrylic and epoxy resins; the polysiloxane also pref. has a layer of a cloth made of glass or carbon fibres. The prod. has the top layer (2) of the flame-resistant polysiloxane with (e.g.) a corrugated finish to give a good grip and to allow liqs. to drain off. It pref. has an embedded layer (4) of a fine glass fabric, produced e.g. by hot pressing two polymers layers with the fabric between them. The underside is bonded durably to the flexible layer (6) whose properties mean that it does not . liberate toxic gases when severely heated. The flexible layer (6) is bonded directly (no adhesive) to the polysiloxane (2) by the "Auma" equipment continuously.  The lower surface of this layer (6) serves to provide good adhesion for the self-adhesive layer (7), but it also produces good insulation against heat and sound and retains the overall flexibility. It enables the bottom layer (8) of protective paper to be applied. @(13pp Dwg.No.1/2)@

Title: Optical system for catadioptric reduction projection - has two lens groups, one positive and another one negative, and polarisation beam splitter
Inventor: ICHIHARA YUTAKA
IPC: G02B17/08
Filed: 1991-03-28

Title: Ring spinning frame - utilises fine sliver from card cans and adequate drafting to obtain a fine yarn
Inventor: STAHLECKER FRITZ
IPC: D01H5/00
Filed: 1991-09-06
Abstract: A process to run a ring spinning frame, has a series of spinning positions, each having a drafting zone being supplied with sliver from a card can. This is fed in with very little twist and only 0.3 to 0.8 gauge. The drafting zone is in two stages, first being threefold, and the second draft has a factor of 65. The ring spinning frame has a series of units, each spinning from a drafting zone, which is fed from sliver from a card can. As this is wider than the spinning unit, the cans are stillaged, with conveyor advancement. The sliver is fed firstly upwards to the guides, where there is an endless belt system, pressing the sliver against stainless flat plates, which are arranged above the card cans, and supported on a mast structure, with outriggers. The sliver descends from the stillage along the sides of the mast. The cans may be held above the frame, on the supports, or they may be at floor level, with a gangway for the operator. The air extraction system is to remove fly, dust and lint. ADVANTAGE - The yarn is ring spun and finer with better quality than other systems. The intermediate process of flyer is dispensed with
