Title: Washing equipment for reusable bottles - has vertically moving needles to spray pressurised water against surfaces of inverted polyethylene terephthalate bottles
Inventor: LEIPOLD WILLIBALD DR
IPC: B08B9/28
Filed: 1991-10-09
Abstract: Reusable containers, and bottles in partic. such as polyethylene-terephthalate reflux flasks, are washed out by means of a high pressure jet system. The bottles are inverted, the spraying device is inserted, and is moved longitudinally relative to the bottles; during the movement the interior of the bottles is sprayed under high pressure. ADVANTAGE - Efficient and removes even obstinate dirt. In an example, a succession of 1.5 1 polyethylene-terephthalate bottles are moved in an inverted state through the equipment where a corresponding number of jet needles (3) have end nozzles (6) for high pressure sprays. The mounting (4) for the needles is moved up and down (7) on guides (9), and water at about 20 deg.C is fed into the needles at high pressure. The machine is arranged so that when bottles (1) are aligned over the needles (3) the latter (3) are moved up into the bottles and the water is forced at 100-200 bar pressure against the surfaces of the bottles. The pressure rotates the spray nozzles (6). The washing cycle lasts e.g. 10 secs. and the washing water flows down out of the bottles.
Patent DE-4137478-A1 (DE)
Inventor: NIEDECKER HERBERT DIPL ING
IPC: A45C13/00
Filed: 1991-11-14
Abstract: In a plastic clip made of two interlocking pieces (1, 10) for closing sausage wrappers, bags or the like, at least one piece (1) is designed as an elongated frame with relatively high side webs (2) in relation to the wall thickness. In the side webs (2) are provided central recesses (4) into which the end of the wrapper gathered together into a plait can be laid. At least the other piece (1, 10), which encloses together with the first piece the wrapper end gathered together into a plait, is provided with a projection shaped as a rib (13) that projects into the inside (5) of the frame and extends parallel to the side webs. The rib (13) ondulates and at the same time exerts a pressure on the plait. A maximum elastic compliance of the clip, thus a maximum adaptability to slightly different plait thicknesses or pressures occurring in the enclosed inner space, is thus obtained, without affecting the resistance of the interlocking connection, and at the same time ensuring a high-quality, constant sealing. In a first embodiment, both clip pieces are identical; in a second embodiment the first piece encloses the plait with U-shaped cut-outs of its side walls which are closed by the second piece.

Title: Curable organo-polysiloxane resin(s) aq. emulsion prepn. - involves controlling partial hydrolysis of alkoxy-organo-siloxane(s) in presence of acid catalyst, followed by emulsification
Inventor: FELDMANN-KRANE GEORG DR
IPC: C08G77/06
Filed: 1991-12-21
Abstract: Aq. emulsions of curable organopolysiloxane resins (I) are produced by partial hydrolysis of alkoxysiloxanes of formula (II) with water in the presence of an acid catalyst, to 30-70% conversion, followed by deactivation of the catalyst and emulsification. In formulae, R1 = 1-8C alkyl or Ph (at least 90% of gps. R1 = Me); R2 = 1-4C alkyl (at least 70% Me or Et); a = 1.0-1.3; and b = 0.2-1.0. The process involves heating (II) (opt. in organic solvent) to 80-140 deg.C, adding the catalyst, adding 5-20 wt.% of the calculated amt. of water for the partial hydrolysis and keeping the mixt. at 80-100 deg.C with distn. of the liberated alcohol; the rest of the water is added continuously, plus a further 1-4 mols. water/mol. alcohol distilled, until the required degree of hydrolysis is obtd. (based on the amt. of R2OH distilled). Aromatic solvents are used, pref. xylene or a xylene-contg. solvent, and the catalyst is a Lewis acid, pref. FeCl3; after reaching the required degree of hydrolysis (pref. 40-70%), the mixt. is cooled by diluting with water, and the emulsifier is added before cooling; pref., R1 = Me and R2 = Et. USE/ADVANTAGE - The process enables the prodn. of (I) with a high content of Si-OH gps., with almost no formation of gelled prods. (contrast prior-art processes).
