Abstract: 1434353 Cellular thermoplastic articles PROFILE EXPANDED PLASTICS Ltd 23 July 1973 [21 July 1972] 34307/72 Addition to 1326192 Heading B5A Cellular thermoplastic articles having a varying density throughout are formed by distributing heat-expandable beads in layers of different density in a mould by feeding them through a filler opening in the mould wall on to a deflector inside the mould to separate the flow of beads into separate streams and deflect the streams to different parts of the mould, while varying the average density of the beads fed to provide the desired density and then heating the beads to expand and fuse them together. At least some beads are pre-expanded. In the manufacture of a wing chair frame, Fig. 3, the lower extremities 13, 14 if the mould 10, 11 define the upper portion of the chair back and front portion of the chair seat respectively. Beads are fed through opening 15 on to deflector plate 16 which extends through a slot 17 in the mould wall and has a flange 18 bolted to the outside of mould part 11. Plate 16 may be deformed so as to give the desired distribution of heavy density beads, e.g. such that the ratio of the rates of flow of the beads in the two streams equals the ratio of the volumes of the mould parts defining the chair back and seat so that these are filled at the same rate.

Filed: 1955-11-30
Abstract: 790,028. Electric tests and control systems. MINNEAPOLIS - HONEYWELL REGULATOR CO. Nov. 30, 1955 [Dec. 1, 1954], No. 34363/55. Class 37. [Also in Group XXXV] Apparatus for controlling the position of the centre of gravity of an aircraft having more than one fuel tank comprises means for comparing the moments of the weight of the fuel in each tank about the position of the desired centre of gravity, thereby determining which tank should lose weight by supplying fuel to the motors, the difference in moment being biased by an amount representing the tolerated deviation of the centre of gravity. As shown (Fig. 2) the fore-and-aft fuel tanks 10, 11 of an aircraft each contain fuel measuring capacitor units 12, 13 of the type described in Specifications 757,205 and 757,295, the units being connected in series across a transformer winding 21 whose centre tap is earthed. Thus the voltage at the junction 23 between the units 12, 13 has a phase which is, e.g., positive if the contents of tank 10 exceed that of tank 11, and vice versa. A positive voltage at 23 produces no output from an amplifier 24 to which it is connected, whereby relay 25 is de-energized and valve 14 is open to feed the motors from tank 10. When the contents of tank 10 fall to make the voltage at 23 negative, amplifier 24 energizes relay 25 to change over its contact 27 whereby valve 14 is closed and valve 15 opened to feed from tank 11. A bias voltage is also fed to junction 23 from manually adjusted potentiometer 32 or 34 as determined by contact 26 of relay 25, representing the tolerated range of centre of gravity of the craft, and producing a snap-action of relay 25. In another embodiment (Fig. 4), the desired position of the centre of gravity is moved by adjustment of a potentiometer 55, and the tolerances adjusted by potentiometers 59, 62. Potentiometer 55 may be replaced by fixed resistors, and the earth point switched from one position to the other when a sudden change in load is effected.

Title: Automatic machine for preparing "expresso" coffee
IPC: A47J31/40
Filed: 1963-08-30
Abstract: 982,447. Coffee making apparatus. ORGANIZZAZIONE NOVI S.r.L. Aug. 30, 1963 [Sept. 1, 1962], No. 34375/63. Heading A4D. In a coffee making machine, the coffee containing compartment is sealed, during brewing, by hydraulic pressure. As shown, movement of an operating handle 1 in one direction delivers a portion of coffee to one of a number of compartments in the plate 10 and the return movement turns the plate so that the compartment 11 lies under the hot water supply and also operates valve 14 to reverse the flow of water under pressure to ducts 41 and 42. The flow through duct 42 in the direction S operates pistons 6 and 15 so that the former, together with piston 7, rises and the latter is pushed down against compression spring 32. The coffee is compressed by perforated tamping foot 18 and subjected to the action of hot water from duct 45, connected to the boiler, when piston 7 clears the end of the duct. Pistons 6 and 7 continue to rise until the latter operates lever 19 to reverse the direction of flow in ducts 41 and 42. As the pistons descend, piston 7 drives the hot water in cylinder 17 through the coffee and exerts a downward pressure on piston 26 which is converted into an upward pressure on plate 28 by lever 24. The upward pressure seals compartment 11 between polytetrafluoroethylene sealing rings 22 and 23. In another form, having a hot water pump, the hot water itself exerts pressure on a perforated tamping member having its perforations sealed by a spring-urged valve member. At a pre-determined pressure, the valve spring is overcome and the hot water flows through the tamper to transfuse the coffee. The same or a different pump provides an operating liquid for an hydraulic piston arranged beneath the coffee containing compartment, to seal it between plastic members as in the previous form.

Title: Improvement in the manufacture of boards, plates, slabs, tiles and the like
IPC: E04C2/16
Filed: 1947-12-30
Abstract: Boards, plates, slabs and tiles are produced by incorporating dissolved blood albumen into a mass of coarsely-disintegrated wood in the absence of an inorganic binder so as to produce a body of moist but not fluid disintegrated wood, shaping the moist mass into board form, heating the shaped body under pressure in contact with heated press members to a temperature sufficiently high to bring about evaporation of water and maintaining the pressure until a dry board has been formed.  The blood may be obtained from animals, fish, whales or seals and may be in the form of natural blood or of redissolved dried blood.  In addition peat, bark, chopped straw, wood pulp, coke, coal powder, grass and leaves and up to 1 per cent sulphur may be added to the mix.  In a typical example 720 grams of blood powder in five times its weight of water is added to 100 litres of chips and after pressing at 10 kgs. per cm.2 and drying, a board 7 mms. thick and a meter square can be produced.  Specifications 541,944 and 542,966 are referred to.

Abstract: 913,325. Making pure gallium electrolytically. SIEMENS-SCHUCKERTWERKE A.G. Sept. 28, 1961 [Sept. 30, 1960], No. 34991/61. Class 41. Pure gallium is produced by using as electrolyte a solution of Ga(GaX 4 ) where X is a halogen, in a non-aqueous solvent, e.g. an aromatic hydrocarbon, and using an impure gallium metal anode. The gallium complex may be obtained by treating gallium tri-halide with gallium, and extracting the complex with benzene or toluene ; some part of other insoluble metal halides are thereby removed. In a suitable and sealed apparatus, molten gallium 1 forms the anode, connected to an electrical lead 2, above which is the electrolyte 7 which also fills the circulatory tube system 8, 9, 13 and is connected to a reflux condenser 12. A cathode 3 consists of a platinum wire coated with gallium melt, and a voltage of about 15 to 20 v. is applied, to give a high current density at the small cathode. The heating effect thereby created, maintains circulation of the electrolyte by thermo-siphon. Pure gallium in molten state falls into a duct 4 connected to a reservoir 5 by a capilliary 6 prefilled with pure gallium. The gallium may also be produced in powder form by using a lower current density at the cathode.
