Title: Improvements in or relating to indirect extrusion presses
Inventor: SIBLER GUENTER W
IPC: B21C35/06
Filed: 1983-06-06
Abstract: In an indirect extrusion press provided with a gate lock 3 and rearwardly extending indirect-extrusion stem 14, the stem normally extends through a die slide 15 with the rear end of the stem engaged by a loose die 20 disposed in the front end of a billet container 19 behind the stem. After a ram 23 has extruded a billet 21 through the die and the gate lock has been released, the stem is moved forward clear of the die slide as the die is pushed into the slide, which is then moved transversely of the extrusion stem and out to the side of the gate lock housing 1 for cleaning or replacement of the die. <IMAGE>
Patent GB-2149571-A (GB)
Title: Thermal imaging apparatus
Inventor: GOSS ALAN JEROME
IPC: H04N5/33
Filed: 1983-11-08
Abstract: In thermal imaging apparatus infra-red radiation is received by an array of detector elements which generate electrical signals representative of the incident radiation. These are passed along conductors to a silicon switching array which scans them to produce a visual display. However, thermal energy also passes along the conductors giving rise to thermal shorts. By employing the invention this possibility is reduced. A glass microchannel plate 3 is placed between the two arrays and its channels are coated with a layer of tin 6. Since this layer is supported by the plate 3 it may be extremely thin, and hence its cross-sectional area is small compared to its length. Thus although its electrical conductivity is sufficient for transmission of the electrical signals, its thermal conduction is extremely small. <IMAGE>

Patent GB-2154600-A (GB)
Title: Producing and purifying methane
Inventor: FOLEY TERENCE
IPC: C07C7/144
Filed: 1984-02-23
Abstract: A process for the production of methane-containing gases by the catalytic gasification of hydrocarbon feedstocks in the presence of steam and wherein the feedstock is subjected to catalytic hydrodesulphurisation prior to gasification is modified in that at least a portion of the product gas containing methane, hydrogen, carbon oxides is subjected to a separation process comprising contacting said portion of product gas with a polymeric membrane separator, said membrane having a permeation factor which is substantially greater for hydrogen than for methane, thereby to produce a methane containing non-permeate stream and a hydrogen-containing permeate stream which is recycled as reactant for the hydrodesulphurisation stage. Gases produced by this method may be employed directly as a substitute for Natural Gas.
Patent GB-2140199-A (GB)
Title: A method of heating products
Inventor: SCHMID ROLAND
IPC: H05B7/18
Filed: 1984-04-17
Abstract: In a method of heating products 3 in a vacuum chamber 1, e.g. before the deposition of a layer, by bombardment with electrons from a magnetically focussed low-voltage arc discharge maintained in a residual gas atmosphere between an anode and a thermionic cathode (12) which is situated in a cathode chamber (8) communicating with the vacuum chamber (1) through an opening (9), the residual gas atmosphere consists substantially of helium and/or neon. It was found surprisingly that as a consequence a much higher heating output acting on the products (3) is achieved than with argon, the conventional prior art residual gas atmosphere and that also the heating time can be shortened without making the arc discharge unstable. <IMAGE>

Patent GB-2181664-A (GB)
Title: Packed beds
Inventor: PATERSON WILLIAM RICHARD
IPC: B01J8/06
Filed: 1985-10-17
Abstract: Packed beds having a main zone packed with particles having a size or characteristic such as to give the desired characteristics of the bed as a whole, and a second zone adjacent a wall of the reactor and packed with particles selected to have different size and/or characteristics to those of the main zone exhibit many advantages over conventional packed beds, especially in radial heat transfer, and especially in catalytic processes operating at high Reynolds number. The wall-channelling effect may be reduced by using smaller particles in the interstices between the larger particles of the main zone in the second zone adjacent the bed wall. Particles having differing shapes and/or loaded with differing amounts of active catalyst material may also be used.

Title: Water treatment device
Inventor: CLARKE GORDON RICHARD
IPC: C02F1/00
Filed: 1987-08-10
Abstract: A water treatment device comprises upper (14) and lower (10) water containers. A well (21) formed in the bottom of the upper container (14) contains a chamber (25) which houses a water treatment agent. The well (21) extends into the lower container (10) when the upper container (14) is mounted above the lower container (10), and the chamber (25) in the well has grids, at its upper and lower ends, the grids permitting passage of water from the upper end of the chamber to the lower end thereof. A passageway (37) for water formed between the chamber (25) and the well (21) permits a flow of water from the bottom of the chamber (25) to a higher level before allowing a discharge of water into the lower container. An advantage of such an arrangement is that, by preserving a high water level in the well (21) containing the water treatment chamber (25), the water treatment agent is maintained wet. <IMAGE>

Patent GB-2202290-A (GB)
Title: Master cylinder assembly
Inventor: CAMPBELL ROY
IPC: B60T11/22
Filed: 1988-03-21
Abstract: A master cylinder assembly for an agricultural tractor has a body (1) having a plurality of generally axial working bores (2, 3) each containing a pressure piston (4, 5). Generally radial valve bores (10, 11) communicate respectively with the working bores and with a cavity (9) bridging the valve bores to form a transfer passage, fluid flow through which is controlled by valve members (12, 13) in the valve bores (10, 11). The cavity is created by forming a bore in a boss (14) above the location of the valve bores and the valve bores are formed through the bore in the boss, prior to closing off the latter by insertion of a screw plug (16). In Fig 3 the cavity (9) comprises two intersecting boxes with respective caps (23, 24). <IMAGE>
Patent GB-2221973-A (GB)
Title: A hydraulic valve
Inventor: DETERDING WERNER
IPC: F16K31/60
Filed: 1988-09-26
Abstract: In a manually-operated valve controlled by a rotatable member 4 connected to a hand grip 13 which may be turned manually from a predetermined position, the grip is resiliently biased to return to the predetermined position when released. In the preferred embodiment the valve is hydraulic and the hand grip (13) has provision for limited rotation relatively to the valve body (2). To this end, stop pins (20, 21) subject to the action of a helical torsion spring (17) are disposed in the valve body (2) and in the hand grip (13) respectively. Rotation of the hand grip (13) in either direction away from a central position tensions the helical torsion spring (17). Upon release of the hand grip the restoring force provided by the helical torsion spring returns the hand grip to its central position. Maximum rotation of the hand grip is limited by means of a disc (9), rotatable with the hand grip and formed with arcuate slot (22) through which the stop pin (20) extends. <IMAGE>
Patent GB-2214514-A (GB)
Title: Composite particle dispersions
Inventor: WATERS JULIAN ALFRED
IPC: B01J13/04
Filed: 1989-01-06
Abstract: Composite particles are formed by mixing a dispersion of polymer particles with pre-formed core material particles. The polymer particles are stabilised relative to one another, and the core material particles are destabilised in the dispersion so that they are able to make contact with the surfaces of the polymer particles. The process takes place at a temperature above the operative glass transition temperature of the polymer, and in the process the polymer spreads over the surface of the core particle so that the core particle is encapsulated. The process will proceed, and composite particles will be formed, when the interfacial energies of the three interfaces (core/polymer: core/liquid: polymer/liquid) and the relative volumes of the core particles and polymer particles are related to one another in accordance with an equation which is set out in the specification.
