Title: Removing toner residue from photoconductive surface in copier - by passing contact member contg. agent with equal polarity over surface
IPC: G03G21/00
Filed: 1983-01-27
Abstract: The process is intended for removing toner residue from the surface of a photo-conductive medium (semiconductor film 2) used for electrostatic image transmission. The surface is cleaned using a member (e.g. roller 6) of which the polarity is of the same order as that of the toner to be removed, member and surface being moved w.r.t. one another whilst in mutual contact. The member may consist of polar material and/or carry a solvent contg. polar constituents. It may comprise a strongly hydrophilic medium (e.g. tissue paper) carrying a liq. (e.g. iso-paraffin) contg. a solvent (e.g. dichloromethane or decanol) with a dipole moment around 1.0-2.5 Debye.
Patent NL-8301373-A (NL)
IPC: C12P1/00
Filed: 1983-04-19
Abstract: The invention relates to an enzymatic process in which an immobilised biocatalyst containing an enzyme catalysing the formation of a proton generating product, and containing an enzyme catalysing the formation of a proton consuming product, is contacted with a medium containing substrates for the enzymes present in the immobilised biocatalyst. One of the enzymatic reactions is controlled in such a way that favourable pH conditions for the other reaction are generated in the biocatalyst. For example, the urease catalysed hydrolysis of urea can be used to generate nearly optimum pH conditions for the penicillin acylase catalysed deacylation of penicillins. This internal pH control is superior to controlling the pH of the substrate medium by addition of buffers.

Title: Connecting method for interiorly coated pipe lengths - uses cartridge of explosive material on plastically and elastically deformed pipe ends with elastic seal arranged between them
IPC: B21D39/06
Filed: 1985-09-24
Abstract: The method includes an explosive material cartridge (4) on each side of the pipe lengths turned away from the other. The wall of the first pipe length (41) is plastically deformed towards the second pipe (42). The second pipe wall is elastically deformed in the same direction. After deforming treatment of the second wall, it applies its elastic deformation tension to the first pipe wall. The clamp uses an explosive charge and when this is detonated, the coating of each pipe are joined by a bridging ring. An axially extending extension of the coating on one pipe is fused to the inner side of the other pipes coating. An elastic sealing ring is arranged between the pipe lengths.

Title: Process for the preparation of an enzymatic carbonyl- hydrolase cleaning composition containing subtilisin
Inventor: CALDWELL ROBERT MARK
IPC: C12N15/10
Filed: 1990-10-30
Abstract: A description is given of a process for the preparation of an enzymatic cleaning composition which can break down proteins, characterized by containing a mixture of surface-active detergent and new carbonyl-hydrolase mutants derived from the DNA sequences of naturally occurring or recombinant human carbonyl-hydrolases.  The mutant carbonyl-hydrolases are generally obtained by modification in vitro of a precursor DNA sequence which codes for naturally occurring or recombinant carbonyl- hydrolase in such a way as to cause the substitution of one or more amino acid residues in the amino acid sequence of a precursor carbonyl-hydrolase.  These mutant carbonyl-hydrolases have properties which are different from those of the precursor hydrolase and are especially useful in the formulations of detergents.  The substituted amino acid residues correspond to position +123 and/or +274 in subtilisin of Bacillus amyloliquefaciens.
