Patent DE-1924823-A1 (DE)
Title: Terpolymers of ethylene and vinyl acetate with
Inventor: PAUL HEINSTEIN WARNER
IPC: C08F10/00
Filed: 1969-05-16
Abstract: An alpha-olefin (propylene, isobutylene and/or butene-1) is led into the reaction zone and at least 10 weight % of the original monomers in the reaction zone are converted to a terpolymer containing at least 0.2% alpha-olefine which is terpolymerised in the ethylene/vinyl acetate chain, and less than 10% alpha-olefin is added by chain transmission to the ends of the ethylene/vinyl acetate chain. The alpha-olefines act as chain transmitters and also as co-monomers with the vinyl acetate. Ethylene/vinyl acetate/propylene terpolymers can thus be represented by: (CH2-CH2-CH2-C(OCOCH3)H-CH2-C(CH3)H)n.

Patent DE-1930082-A1 (DE)
Title: Oil filter with reversible flow direction
Inventor: MINNICH WILLY
IPC: B01D29/05
Filed: 1969-06-13
Abstract: The flow direction of the liquid being treated alternates through the filter.

Patent DE-2040852-A1 (DE)
Title: Weft detector fork - incorporating grid suitable for very coarse yarns
IPC: D03D51/34
Filed: 1970-08-18
Abstract: A 2-pronged weft fork acts in conjunction with a corres. 2-space grid in monitoring the presence of coarse weft yarn in the warp shed. The forks and grids are pivot-mounted on the lifter bar synchronised with weft insertion. When weft is present, the yarn prevents the fork entering the grid. In the absence of weft, the fork drops into the grid and through a reed switch and bar magnet causes the immediate stoppage of the loom. The device is suitable for either standard single-shed looms or double-cloth looms with upper and lower sheds.
