Title: Photocopying apparatus
IPC: G03G15/00
Filed: 1980-07-09
Abstract: In commercially available photocopiers having a liquid developer and a sheet stripping device subsequent to the transfer station, there exists a problem with "edge deletion" wherein a marginal portion of the copy sheet (40) is unable to contact the photosensitive surface (15) and therefore accept or receive a developed image. In order to eliminate "edge deletion", the present device provides a sheet stripping blade (48) which is movable between a first position in which the blade overlies a marginal portion of the photosensitive surface (15) at the transfer station (42) to engage a corner of the leading edge of the copy sheet to thereby guide the leading edge to transport mechanism (50, 54) and a second position in which the blade is removed from its overlying position to enable the copy sheet to engage the surface (15) at the marginal portion. The device further has a sheet hold-down member (105) for reducing the extent of "image deletion" in the corner of the copy sheet (40). In further aspects, a liquid metering roller (38) and cleaning blade (58) are provided.

Patent GB-2093994-A (GB)
Title: Identification of beta- lactamase
IPC: G01N33/04
Filed: 1982-03-03
Abstract: Beta-lactamase is identified by monitoring competition reactions between a chromogenic substrate, e.g. nitrocefin, and various competing substrates, e.g. cefoxitin, moxalactam or MK 0787. Detailed study of these reactions show unexpectedly marked variations in the reactivity (affinity) of these enzymes for the different beta- lactams. On this basis an assay for the identifying "unknown" beta- lactamases is based on comparing their behaviour in the competition reaction with affinity data on known beta-lactamases. The chromogenic substrate and a selection of the most useful beta-lactams are provided as a kit. It can contain prepared mixtures of the beta-lactams and chromogenic substrate. The assay can be carried out visually using micro-titre plates and a simple scoring system or more quantitatively by spectrophotometric scanning. It can be used for the rapid identification of beta-lactamases in the laboratory or for the identification of gram-negative bacteria based on the beta-lactamases which they produce.
