Smooth skinned, void free, cellular articles are made from a polyvinyl aromatic compound, such as polystyrene, by extruding an expanded sheet having 85% by volume of closed cells and a shrink of at least 5% under standardized conditions; comminuting the sheet, by for example chipping or cutting, in such a way as to preserve the cellular structure; and finally sintering the resultant particles in a closed mould, care being taken that at least 1% of organic liquid blowing agent is present in the mould per 20% shrink. The material used may or may not be scrap and if the residual blowing agent content is not up to the desired level more agent may be added after as a liquid before or after comminution or as a vapour in which the particles are stored. The shape and colour of the particles may be varied to produce decorative effects. Elastomeric material such as natural or synthetic rubber may be added to the aromatic compound.

Abstract: 1380478 Flame cutting MESSER GRIESHEIM GmbH 19 Dec 1972 [20 Dec 1971] 58505/72 Heading B3V In a method of cutting a workpiece 20 by a cutting torch 12, the torch is positioned closer to the workpiece 20 during the preheating step. The torch 12 is movable by a piston and cylinder device 28 within a guide frame 14 which is secured to a drive shaft 16 of a motor 18. In operation, the torch 12 is quickly pivoted by the motor 18 towards the workpiece 20, e.g. a continuous casting, slab or square billet, until a switch 42 on an arm 40 mounted on the drive shaft 16 is actuated by a cam 44 (position I), whereupon the motor 18 is slowed to allow the workpiece 20 to be preheated by preheating flames 17a and 17 issuing from a torch head 36 or from a separate preheating torch (38), (Fig. 2, not shown). When the switch 42 is again actuated by a second cam 44, the motor 18 is driven at the desired cutting speed and the torch 12 is raised by the piston and cylinder device 28 from its lower preheating position II determined by a stop ring 26 to a raised cutting position III. A roller (50), (Fig. 3, not shown), is mounted on the torch 12 so that any distortion of the workpiece raises the roller 50 causing the torch 12 to be moved into the protecting guide frame 14. The gap between the motor drive shaft 16 and the workpiece 20 is kept constant by a rod 48 connected to the motor 18. The pre-heating flame may be intensified by iron dust.

The platforms 41 are reciprocated on rollers 43, Fig. 3, mounted in a slot in a partition wall 22 and screened from the furnace by the platform 41. Lifting beams 33, of similar construction, are carried by pillars 46 enclosing the coolant supply tubes and sliding in sleeves 48 passing through the partition wall 22. Beams 83, movable both vertically and horizontally, Fig. 9, may be used with stationary bridge structures. In a furnace having vertically and horizontally movable cooled bridge structures 131, Fig. 12 extending part way through the first heat zone 113 of the furnace. Conventionally supported skid rails extend between the movable supports 131. Solid refractory supports extend from near the ends of the skid rails to the discharge end of the furnace, and movable refractory beams 141 extend from near the end of bridge-like supports 131. The supports 131 and refractory supports 141 are linked for common longitudinal movement, so that a slot in a refractory beam 141 can fit snugly round the end of a cooled truss 131. The beams 141, 131 are independently lifted however, the arrangement being such that, from their extreme position nearest the charge end, both sets of beams are raised and moved forwardly a half stroke, the cooled trusses 131 are then lowered and the beams and trusses complete the forward stroke, the refractory beams 141 are lowered and the beams and trusses complete the cycle, so that billets 20 packed closely in transit through the preheating zone and into the first heating zone, are spread out in the second heating zone and in the soaking zone. Downwardly directed flues 165 are provided at the end of the preheating zone A furnace is described in which downdraught flues at the discharge end prevent cold air entering the furnace proper, Fig 6 (not shown).

Abstract: 1,244,759. Semi-conductor devices. ASSOCIATED SEMICONDUCTOR MFRS. Ltd. 11 Dec., 1968, No. 58828/68. Heading H1K. A method of interconnecting two devices T 1  and T 2 , in an integrated circuit, which are mutually isolated by a groove 6, comprises providing a conductive metal bridge 19 over the groove. The steps of forming the bridge comprise providing a plug of material at the surface of the semi-conductor body between the two devices T 1  and T 2 , forming a conductive metal layer between the electrodes 15 and 33 of the two devices, removing the plug by etching so that the surface of the semi-conductor body underlying the conductive metal layer is exposed, and etching a groove 6 into the semi-conductor body to isolate the two devices. An insulating layer of silicon oxide, silicon nitride, silicon carbide or aluminium oxide is provided on the surface of the semi-conductor body which may be of silicon, germanium or gallium arsenide, and serves as a mask during processing. The plug is of aluminium and is removed by etching with hot sulphuric acid. The electrodes 12, 13, 15, 32, 33 and 35 are of aluminium coated with titanium which itself is coated with gold, the gold layer later being thickened by electroplating. The plug may alternatively be of copper and the interconnections of molybdenum, nickel, platinum or silver. After the removal of the plug, the groove 6 is formed by etching the semi-conductor body with hydrazine and water in equal molecular ratio, the body having been so arranged that the groove orientation is parallel to the intersection of the <111> crystal planes with the body surface parallel to the <100> crystal plane so that the etching wil result in a groove of V-shape cross-section.

Title: Improvements in ink drop writing systems
IPC: B41J2/115
Filed: 1969-12-19
Abstract: 1293910 Ink-drop writers A B DICK CO 19 Dec 1969 [23 Dec 1968] 62072/69 Addition to 1211955 Heading G4H In an ink drop writer where a stream of ink drops charged by a video signal is projected through an electric field at paper to be written on, the phase of the ink drops is periodically tested by a video test signal which if the phase is correct charges alternate pairs of drops to be charged and uncharged respectively which when projected at a sensor generates a signal of a particular frequency, which is absent if the phase is wrong. Pairs of drops when charged by the test signal will separate and merge with the adjacent uncharged drops, so halving the number of drops in the stream. In Fig. 2 an ink drop writer 40 is driven across paper 50 and back again by motor 52 through half sector gears 56, 64 and on its return to its home position operates switch 74 to stop the motor and generate the video test signal. The electric field deflecting plates 41 do not extend to the home position so that ink drops are projected at a sensor which is either a conducting rod or a rod of piezoelectric material. If the ink drops are correctly phased, the sensor produces a 16-5 kHz signal which in the circuit of Fig. 5 passes filter 105 and is integrated at 107 to operate Schmitt trigger 108. If the 16.5 kHz signal is absent inverter 109 produces an output which together with the output of multivibrator 112 and the delayed signal from home position switch 72 opens AND gate 110 to flip bi-stable circuit 114. One of two OR gates 116, 118 are thereby opened to reverse the phase of the 66 kHz signal generating the stream of ink drops. The delayed home position switch signal restarts the motor via AND gate 126 if the phase detecting circuit has operated. The video test signal is generated by circuit 104 which produces two 7.5 Ás. pulses with a 7.5 Ás. interval for every 35 kHz signal pulse input provided by dividing the 66 kHz signal generating the ink drops.
