Filed: 1973-11-28
Abstract: 1457757 Si impregnated carbon fibre/carbon composite DEFENCE SECRETARY OF STATE FOR 19 Nov 1974 [28 Nov 1973] 55242/73 Heading C1A Carbon fibre/carbon composite materials are treated by immersing the material partially or wholly in molten silicon. Immersion in the Si is preferably held at or just above its melting point (i.e., 1450-1550‹ C.) for a period sufficient to convert the C matrix to one composed essentially of SiC and Si. Alternatively immersion may be just sufficient in duration to allow Si to penetrate the C matrix without formation of SiC; the latter may be produced by a subsequent thermal treatment in the absence of molten Si. In an example, carbon fibre/carbon composites were prepared having either crossply or unidirectional fibre orientation by coating high strength fibres with a phenolic resin, laying the coated fibres in a mould to yield the desired fibre orientation and heating the moulded shape at 800-900‹ C. in N 2  to carbonize the resin: xylene is used to build-up the C matrix. The Si impregnation is carried out at 1450-1550‹ C. for 30 min. in vacuo: the C composites took up 10-39 wt. per cent of Si depending on fibre orientation. Density and mechanical properties of the Si treated composites are detailed.

Abstract: 1363739 Spray carburetters ROBERT BOSCH GmbH 2 Dec 1971 [11 Jan 1971] 55891/71 Addition to 1336606 Heading F1B Fuel injection system for a mixturecompression, spark ignition I. C. engine with continuous injection into the inlet manifold, as claimed in claim 1 of Specification 1336606 has a pressure control valve which varies the pressure of the fluid as a function of engine operating characteristics and has the tension of a closure spring of the valve controlled by a first temperature responsive element and a second temperature responsive element which is arranged to oppose the closure spring for a brief period after starting. The system provides a very rich mixture immediately after the engine has started and the cylinder walls are cold and then reduces the strength of the mixture, while still providing a richer than normal mixture, until the cooling water reaches its operating temperature. The mixture strength is dependent upon the position of a slide valve 12, the endface 13 of which is acted on by the pressure of fuel in a chamber 31. A pipe 50 leads from chamber 31 to a diaphragm valve 57, 58 which acts as a controlled pressure relief valve. The diaphragm is pressed against the duct 57 by a spring 59 which abuts a cup 64 supported by a first temperature responsive element 63, which when cold, effectively reduces the pressure of the spring. The element 63 is responsive to the cooling water temperature. The second temperature responsive element is a bi-metal strip 68, which when cold, acts against the spring. An electrical heater 69 operates as soon as the engine is started and quickly heats the strip 68 so that it bends away from the spring and has no further effect.

Abstract: 1,245,154. Packaging machines; affixing sealing strips. AVERY PRODUCTS CORP. 27 Nov., 1968 [28 Nov., 1967], No. 56331/68. Headings B8C and B8F. A method of opening, filling and closing bags 8 comprises the steps of applying at least one adhesive strip 47 to opposite sides of a bag near the opening thereof so that opposed portions 48 of the strips project above the opening without being pressed against each other, pulling at least one projecting portion to pull apart opposed sides of the bag, filling the bag after it is opened, and closing the bag by pressing the projecting strip portions against each other. As shown, tubing of transparent synthetic resin or other material is fed through a heating element 4, for applying a transverse seal 5, and past a blade 7 which cuts the tubing to form separate bags 8 which fall into a support 14. Label-feeding devices 9, 10 co-operate to feed the labels to the location where the bags are filled through an opening 12, the labels being carried on bands 20 and the device 9 including a carriage 18 slidable back and forth in a horizontal direction. The bands 20 move over dispensing edges 24 which strip the labels from the bands, the labels being then pressed by rollers 31 on to the opposite sides of the bag 8 and the latter being then lowered by the support 14 when the bag is filled; the carriage 18 being moved to the left as seen in Fig. 2 causes the rollers 31 to press the projecting portions of the labels together to seal the bag. The support 14 being again lowered allows a pin 38 to pierce a hole 46 through the bag and labels and an arm 36, upon striking a stop 37, causes the flap 35 of the support 14 to swing to allow the filled bag to fall into a container. Instead of forming bags from a tube, bags fed from a pile to the support 14 may be used.

Abstract: 1,204,537. Valves. SOC. ANON. FRANCAISE DU FERODO. 12 Dec., 1967 [13 Dec., 1966; 6 Dec., 1967], No. 56422/67. Heading F2V. A valve, usable in a vehicle air conditioning apparatus in which it is interposed in the hot water circuit of a radiator, comprises a water inlet 12, a water outlet 13 and a seat 14 formed therebetween, the seat being engageable by a diaphragm 15 which is clamped at its periphery and is movable in relation to the seat either by a mechanical actuator or by a fluid thermosensitive element. The mechanical actuator consists of a three-part piston 45, 46, 47 which is bodily movable within the valve casing 16 as a result of movement of a cam 28 which engages a follower 41 rotatably held in the piston upper part 45. The thermosensitive element comprises a bulb 30, which is normally disposed in the current of air immediately downstream of the radiator, and which communicates with the upper side of a diaphragm 50 clamped at its periphery between the piston parts 46, 47, the underside of the diaphragm engaging a rod 29 slidable within the piston lower part 47. Movement of the rod is transmitted to the diaphragm 15 by two springs 31, 32 of which the former engages a reinforcing socket 25 which is embedded in the diaphragm 15 and through which the rod slidably passes. In operation, with the mechanical actuator, and hence the piston, in the position shown, expansion of fluid within the thermosensitive element results in diaphragm 50, and hence rod 29 and diaphragm 15, moving downwardly towards the seat 14, such movement resulting in a partial closure of the flow passage 11 (Fig. 3, not shown). Upon the actuator, and hence the piston, being moved to its lowermost position (Fig. 4, not shown), the flow passage becomes fully closed even in the absence of fluid expansion in the thermal element. In the event of such expansion subsequently occurring, then it is accommodated by downward movement of the rod 29 into a chamber 24 defined by the central portion of the daphragm 15 (Fig. 5, not shown), such movement of the rod not affecting the state of the valve. The mechanical actuator may attain positions intermediate to those described, but in all cases the thermosensitive element moves with the piston by virtue of the fact that it is welded to it at 54 and its capillary tube 52 passes through a longitudinal slot 38 formed in the valve casing 16.
