Title: Refrigerators
Inventor: WALL CHRISTOPHER DENHAM
IPC: B01D53/26
Filed: 1985-08-29
Abstract: The invention relates to a method of reducing the formation of frozen condensate on a refrigerated surface comprising the step of covering at least part of a refrigerated surface such as a wall or walls of a refrigerator or freezer with a moisture absorbent substance. By absorbing the moisture in the atmosphere surrounding the refrigerated surface, the condensation and freezing of the condensate on the refrigerated surface is prevented. In one form of the invention a structure is provided to support a moisture absorbent substance such as crystals of silica gel (17), the support structure comprising a plurality of containers (16) for the silica gel connected to one another by generally open webs. The structure is rendered self supporting by a framework of wires. Alternatively, a single container (100) comprising bent expanded metal sheets, for instance, may be used to contain the moisture absorbent substance. <IMAGE>

Filed: 1985-11-21
Abstract: A plastics web 12, for example in bag manufacture, is cut by an endless band 10 extending round rollers 11 and generally in an inclined plane to the web. Guide rollers 13 make a length 10a of the band at right angles to the web. The band may provide multiple teeth with cutting edges and is moved at a high speed, e.g. 200 to 700 m/min, so that the web is cut by movement of the band through only one or a few teeth pitches, for example in 0.5 millisecond. The web is moved into and out of engagement with the band. The web may be preformed bags but the cutter may be associated with welding heads. The web is stationary during welding and cutting. <IMAGE>

Title: Tool identification and condition monitoring
Inventor: SWIFT KENNETH GEOFFREY
IPC: B23Q17/24
Filed: 1986-12-23
Abstract: The invention relates to an electro-optic device, which is capable of both identifying and monitoring the condition of material processing tools such as those used in cutting and forming operations. This leads to improvements in the efficiency of automatic or computer-integrated manufacturing procedures, wherein tools are inspected on the basis of signatures derived from an optical scattering system.
