Title: Shredding cheese
Inventor: HOOK JEFFREY
IPC: B26D7/06
Filed: 1991-05-01
Abstract: A machine for shredding large blocks of cheese or other materials comprises a framework having a platform (24) which is designed to receive a block of cheese or like material. A pusher plate (33) is arranged to be driven by a ram (31) via a piston (32) across the platform (24) to advance the block of material towards a cutter means. The cutter means is located in a housing (18) at one end of the framework and has a vertical wall in which an aperture is provided and in which aperture is mounted a rectangular open frame (25). A plurality of cutting wires (26) extend across the frame (25) and serve to separate a block of material advanced by the pusher plate into sections. The material is then shredded by an apertured disc which is supported on a mounting (16) for rotation on the housing (19) and arranged to be driven by an electric motor (7) via a pulley system (10, 11, 12). Although primarily intended for shredding cheese, the machine can also be used for shredding other materials. <IMAGE>

Patent GB-913764-A (GB)
IPC: C08G59/62
Abstract: 913,764. Lithographic printing plates. ALGRAPHY Ltd., and ADAMS, R. A. C. Aug. 26, 1959 [Sept. 2, 1958], No. 28197/58. Class 98 (2). [Also in Group IV (a)] Lithographic printing plates may be coated with light sensitive materials prepared (see Group IV (a)) by (i) reacting (a) a linear epoxy resin which is an organic solvent soluble polyalcohol with more than one but not more than two terminal epoxy groups, with (b) an aliphatic alcohol containing two primary alcohol groups and at least one secondary alcohol group per molecule in an amount substantially equivalent to the epoxy content of the resin (one primary alcohol group being equivalent to one epoxy group) such that the hydroxyl equivalency of the alcohol is less than that of di-p-phenylol- 2,2-propane (i.e. less than 114), and (ii) esterifying with cinnamic acid or an esterifiable derivative thereof (e.g. cinnamoyl chloride), the solvent soluble polyether alcohol thus produced which contains no epoxy groups but has a lower hydroxyl equivalency and higher molecular weight than the original epoxy resin. Compounds specified are :-(a) epichlorhydrin/bisphenol A; (b) sorbitol. In Example (1) a solution of such a cinnamic ester and Michler's ketone in cyclohexanone/toluene was whirlcoated on to an aluminium plate; the plate was then exposed, developed in the same fresh solvent, rinsed in toluene, dried, and hand-inked by normal lithographic technique. A second example is similar. Specifications 713,947, 717,708, 717,710, 717,712 and 743,455 are referred to.
Patent GB-2252147-A (GB)
Title: Control of a gas flow
Inventor: PENDLETON CARL
IPC: F16K7/08
Filed: 1992-01-10
Abstract: A valve for the control of a gas flow has two cylindrical members 2, 4 adjacent to one another and defining a flow passage. Secured between the cylindrical members is a sleeve of gas-impermeable material, for example coated nylon, folded back on itself. In the valve condition shown gas may flow through the sleeve without hindrance. When one member 2, 4 is turned relative to the other, the sleeve is twisted, to form a narrowed aperture, so restricting the gas flow. Ultimately, the restricted aperture may disappear, the sleeve then forming a tautened barrier substantially preventing gas flow altogether. The valve is particularly used for controlling flow of air in air-conditioning apparatus. <IMAGE>
Patent GB-2253943-A (GB)
Title: Diamond heterojunction diode
Inventor: KOBASHI KOJI
IPC: H01L29/16
Filed: 1992-03-20
Abstract: The diode has an improved rectifying characteristic with a small reverse current and a large forward current. Three layers are formed on a low-resistance p-type silicon substrate 1 by microwave plasma CVD and comprise a B-doped p-type semiconducting diamond layer 2, an insulating undoped diamond layer 3A (thinner than 1  mu m), and an n-type semiconducting layer 4. Ohmic electrodes 5, 6 are formed on the n-type semiconducting silicon layer and the substrate. Under a forward bias, the electric field across the intermediate insulating layer accelerates the transport of holes and electrons. Under a reverse bias, the energy band structure has a well in addition to a potential barrier due to the intermediate layer thus preventing holes from transporting from the n-type semiconducting diamond layer to the p-type semiconducting diamond layer, resulting in an improved rectifying characteristic. <IMAGE>

Title: A shower
Inventor: RAWLINGS PETER
IPC: B05B12/10
Filed: 1992-05-12
Abstract: A shower head has valve means and/or diverter means. The valve means is adapted to permit any static water contained therein or in a supply pipe or hose connected thereto to be flushed to waste or drain before water is dispensed from the shower head. This reduces the risk of bacterial multiplication in shower heads and the associated pipes or hoses. As shown in Fig 1, water supplied via conduit 21 to head 22 can be recirculated to a drain via conduit 23 by moving valve member 24 to the dotted line position. Valves such as 24 may be actuated by the temperature or pressure of incoming water to move to the position permitting the water to pass through head 22. <IMAGE>

When the lid is closed, the panel is accommodated within the top opening of the box, the projecting parts of the supporting means engage over the inturned top flange of the upper metal frame and the retaining means can be engaged under the inturned top flange. In one form of the invention the lid is hinged to one edge of the box by means of U-shaped metal strips 23 riveted to the panel and passing through slots 24 on the flange. The supporting means comprises two battens stapled along the length of the two opposite side edges of the lid and projecting over the sides and the free longitudinal edge. The lid is secured by a swivel member 26 engaging beneath the inturned flange. Strip metal may replace the battens 23. The lid may be removable and the retaining means may then comprise, in addition to the swivel member, a fixed metal strip on the opposite margin of the lid panel adapted to engage beneath the corresponding inturned flange. For a collapsible box having the side and end panels hinged to the lower metal frame, and the end panels hinged to the upper frame 21, Fig. 6, the lid may have abutment means 46 to prevent the side panels being pushed in when the box is filled and so prevent pilfering when the box is secured and banded with metal.
