Patent GB-1022814-A (GB)
Title: Moulded optical elements
IPC: G02B1/02
Filed: 1963-12-17
Abstract: An infra-red transmitting optical element is made by placing a mixture of microcrystalline magnesium oxide powder containing between 0.5 and 10%, and preferably 1%, by weight of lithium fluoride in a pressure mould, exerting a moulding pressure of between 9,500 and 57,000 pounds per square inch on the powder mixture while maintaining the temperature of the mixture between 700 DEG  and 850 DEG  C. for a time sufficient to ensure that the mixture becomes homogeneous, and thereafter releasing the pressure and cooling the mould.  The moulding pressure is exerted on the heated powder mixture advantageously for two minutes and preferably in an inert atmosphere or vacuum. The moulding mixture is preferably made by blending submicron magnesium oxide powder with submicron lithium fluoride powder for at least one hour at room temperature, and before being hot pressed the mixture may be compacted by pressing at 10,000 pounds per square inch in the pressure mould at room temperature. Suitable pressure moulding apparatus is described, substantially similar to that described in Specification 934,421.

Abstract: 1533712 Bending sheet material AMERACE CORP 8 Dec 1975 [23 Dec 1974] 50255/75 Heading B6J A sheet 202, Fig. 7, of somewhat brittle plastics material, is first folded into U-shape as shown at the bottom of Fig. 7, and then the upper ends are folded over to form the sheet into an envelope suitable for use in enclosing battery plates heat being applied locally at each folding. The sheet is laid on fold plates 106, 108, Figs, 4 and 7, which are initially horizontal and hinged at 102, 104 to a fixed assembly. In operation, a vertically slidable folding blade 110, Fig. 1, is first moved downwards by an air piston until the blade presses the sheet against a vertically slidable anvil 80 urged upwardly by springs 38, 40. The blade is then moved further down, pressing the anvil downwards and at the same time causing the plates 106, 108 to swing upwards to the position of Fig. 7, while heat is applied by a heater 152. A slight further downward movement of the blade causes the upper edges of the sheet to be folded inwards, while heat is applied by heaters 154, 156. The plate 106 is supported at one end by hinges 102 on a bar 98 secured to arms 54, 56 pivoted on stub shafts 62, 72, and connected by a bar 84 mounting spring-urged pins 90 and single-bars 94 with upstanding portions 94a.

Abstract: 1495726 Ignition systems DUCELLIER ET CIE 25 Nov 1974 [29 Nov 1973 9 July 1974] 50887/74 Heading F1B An ignition system for an internal combustion engine comprises a tachometric generator 3 which receives through a signal shaping system 2 signals from a position detector 1 co-operating with an element driven in rotation proportionately, to the engine speed which generator feeds an integrator element 4 which supplies a voltage U 1 proportional to the angular spacing between a reference position and the angularly variable position of the element, an amplifier 5 which in series with the integrator supplies a voltage U2 which is a function of the engine speed and a comparator 6 which receives the sum of the voltages U1 + U2 and compares it with a threshold voltage U3 and when U1 + U2 coincides with U3 supplies an output signal which is used to trigger the establishment of the current in the primary winding of the ignition coil 9. A resistance may be connected at a point of the system for shaping the signals from the detector and also through a diode to the input of the comparator to supply a voltage U4 to the latter so that at low engine speeds the start of current flow in the primary winding of the coil is effected when U4 = U3.

[Also in Division B8] An extrusion blow-moulding machine for producing, filling and sealing thermoplastic bottles, comprises an extruder 11 to extrude a thermoplastic parison vertically, a plurality of two-part moulds 7 1 -7 10 , means to open and close the moulds, means to blow, fill and seal the bottles while in the moulds, and means to drive the moulds continuously in a closed path successively under the extruder and blowing, filling and sealing means. In the Figures, the moulds, e.g. 7 1 , Fig. 2, are carried on the radial arms 8, of a turn-table and opened and closed by jack 43 acting through toggle mechanism 41, 42 and co-operate with a swinging extruder 11 pivoted on shaft 12. A reservoir 14 supplies nozzle 16, with filling material via pipe 44, and may be refilled at 15. The nozzle 16, Fig. 7, comprises a pair of concentric tubes defining passages 56, 57 for applying blowing air and suction respectively from pipes 48, 49, Fig. 6, respectively, the outer tube being flared outwardly and closing the orifice 54 formed by a further surrounding tube, the passageway 58 formed thereby being connected to a supply of filling material from pipe 44. The central tubes are vertically reciprocable by means of jack 73 acting through rocker arm 74 on to head 52, biased upwards by spring 53. The nozzle 16 is reciprocated vertically also as a whole by jack 71 acting through crank 72 and rollers 62 against ridges 46, 47 and is reciprocated horizontally by jack 64 acting through its rod 65 and arm 66 connected to supports 63, 67 and forming a parallelogram arrangement with arm 68. A sterile air dryer 69 may be used to dry the nozzle. The swinging of the extruder is regulated by cam (32, Fig. 4, not shown), rotated by drive (31) from motor (28), a further drive (30) from which regulates the turntable rotation. Operation.-During the rearward swing of the extruder, grippers 23 open, move up and are then closed on the extruded parison and lowered during the forward swing of the extruder while being partially pre-blown through the die and initial mould closure. A further blowing after complete mould closure forms a flange, nipped off at the top of the mould and the parison is severed, the extruder then swinging back for similar subsequent operations. The closed mould continues to rotate, the neck being held by the grippers, to engage nozzle 16 which effects the blowing proper and filling. The bottle is then sealed at the neck (Figs. 8, 9, not shown) before trimming and mould opening.

Abstract: 1286286 Coated nuclear fuel particles UNITED KINGDOM ATOMIC ENERGY AUTHORITY 7 Oct 1970 [20 Oct 1969] 51437/69 Addition to 1081447 Heading B2E [Also in Divisions C1A and G6C] Nuclear fuel particles are coated by tumbling in a drum into which powder grains previously treated with a binder and a mould release agent are introduced and softening the binder by contacting the treated grains with a solvent for the binder as the grains enter the drum such that the particles acquire an outer coating of the grains by a snowballing effect, and a mass of the coated particles is subjected to a pressure moulding process to form coherent artefacts. The grains may be a granular carbon or graphite. In the Example calcined petroleum coke was crushed, graphitised and mixed with a solution of phenol-formaldehyde resin to produce coated graphite grains. A solution of stearic acid in white spirit was mixed with the resin coated graphite grains and the white spirit evaporated from the mixture. A batch of nuclear fuel particles bearing fission product retaining coatings of pyrocarbon and silicon carbide were tumbled in a drum into which the treated graphite grains were fed. The grains were sprayed with a solvent for the resin as they entered the drum. The product was then pressed in a stainless steel dye heated to 800‹C. to form a nuclear fuel compact comprising fission product retaining fuel particles embedded in graphitic matrix material or high density.
