[Also in Division H1] A record card 8 is held on a carrier 7 between strips 30, 31. and carrier 7 is coupled by arms 5, 6 to a base plate 2, so that as the carrier 7 is pushed in, it is raised towards member 11 bearing sensing pins 27. On initial movement of carrier 7, spring 20 is tensioned until a point is reached when spring 20 is able to draw carrier 7 inwards until stop 29 engages a roller depending from member 11. After this position, carrier 7 and member 11 are held together by spring 20 in the longitudinal direction, but further force exerted on handle 26 raises carrier 7 and member 11 on respective pairs of arms 5, 6 and 9, 10 against the action of the spring-biased pins 27 until a dead centre is passed, when spring 20 moves carrier 7 and member 11 to a final stable reading position with arms 5, 6 and 9, 10 inclined to the right. A cover plate 24 may be provided to seal aperture 23 in front panel 1.

Abstract: 1,105,955. Wind tunnels. BRITISH AIR. CRAFT CORPORATION (OPERATING) Ltd. 21 Sept., 1965 [21 Sept., 1964], No. 38447/64. Heading B7G. [Also in Division F1] An ejector comprises a duct formed between a central body 14 and a casing 10, downstreamfacing nozzles 19 distributed across the duct and supplied with air from branched passages 20, 13, 17, 18, each branch having such an airflow resistance that air is discharged from the nozzles to provide a substantially uniform mass flow rate across the whole section of the duct. The ejector is used for simultating the air flow pattern around the intake or exhaust of an airbreathing engine. An annular baffle 22 may be arranged in cavity 13 to equalize the flow rates between each set of vanes 17 and 18. In another embodiment only one set of vanes is present, air being supplied to both ends of the vanes which are each divided into two passages by a lengthwise wall. Both passages communicate with the air supply at their outer ends. One passage has the nozzles and a restriction at its outer end whilst the other passage constitutes a duct supplying air to the inner end of the first passage.

Patent GB-1566946-A (GB)
Title: Method and apparatus for injection moulding of eypanded plastics articles
IPC: B29C44/04
Filed: 1977-09-15
Abstract: In the process, a mould cavity (14) is filled with a gas which prevents foaming of the blowing-agent-containing plastic melt entering the mould cavity and by which the melt is gradually displaced out of the mould cavity. In order to prevent, during the mould-filling operation, the gas bubbles remaining behind the flow front of the melt from forming deformations in the moulding, they are evacuated out of the mould cavity directly after their inclusion by the melt. In a thermoplastic foam injection-moulding machine, the mould cavity (14) of the device for carrying out the process can be pressurised or relieved via a channel (114) and a valve (22, 23). In the regions (126) in which the melt seals the escape route of the gas via the channel (114) there is provided in the mould wall in each case at least one capillary-active, gas-permeable apparatus (127) which can be connected via at least one relief space (128, 129) and a shut-off valve (3) associated therewith to the open air. Even mouldings with a relatively complicated shape can thereby be produced faultlessly and with a smooth surface. <IMAGE>

Title: Tyre inflating valves
IPC: B60C29/02
Filed: 1963-10-03
Abstract: 986,784. Valves. GOODYEAR TIRE & RUBBER CO. Oct. 3, 1963 [Oct. 24, 1962], No. 38930/63. Heading F2V. The inner and outer chambers of a tubeless tyre are connected to the outlets 14, 13, Fig. 2, respectively, of a valve body 11 housing a valve core 28 and a further closure comprising an "O" ring 35 disposed between flanges 34 on a stem 33, which ring co-operates with an opening 36 leading to the outlet 14. The body 11 has a flange 15 whereby it is attached to the rim, a rubber washer 41, Fig. 3, being interposed between the rim 3 and nut 43. When inflating air enters a chamber 24, Fig. 2, in the body 11 it flows directly to the outer chamber via a port 31 and the outlet 13; concomitantly it opens valve 35 and enters the inner chamber until the pressure therein closes the latter. Pressure in the outer chamber is measured in the normal way but the pressure in the inner chamber cannot be measured until the valve core 28 is removed; in this case the gauge needs a long actuating-pin. Outlet 14 has a larger flow area that outlet 13 so that the inner chamber is inflated to a higher pressure than the outer one. Both chambers are deflated by removing the inner body member 20. In a modification, the washer 41, Fig. 3, is provided with a metal reinforcing-band 44 and the valve 50 for the inner chamber consists of a stem 47 with a seal 51 co-operating with a seat 52, the stem 47 being connected to the pin 37 of the valve core 28 by a spring 54; a light spring 53 is disposed around the stem 47. A relief valve 40 is disposed between the chambers to ensure that the desired pressure in the inner is not exceeded. In another modification, the valve 64, Fig. 4, for the inner chamber has a valve core 64 engaging a tapered body part 63 and is of similar construction to the core 28 but the loading spring is lighter so that the valve will open due to air pressure downstream of core 28. The inner housing is in two parts 65, 66 to permit installation of core 64; the parts 65, 66 may either be joined by threading and bonding or by swaging or press-fitting. A heavy spring may hold the core on to the part 63 whereby the latter also acts as a relief valve when the pressure in the inner chamber exceeds the desired value. The heavy spring may seat on the core 28 or a shoulder in the body and the tapered part may be replaced by a flange. The housing parts 65, 66 may be joined by a bellows spring, one formed with grinding flanges the main housing part also acting as the relief valve. A metering opening may be disposed in the body between the two inflation valves. Sealing means e.g. 55, 57 are provided between the inner and main body portions.

The airflow in which the stripped fibres are carried expands in the tapering space A bounded by the surfaces of the cylinder 10, the stripper 15 and a condenser lattice 16 where it passes over a suction duct 20. Instead of a lattice, a rotary cage condenser may collect the fibres which may be used for non-woven fabrics, or the fibres may be condensed to a sliver and coiled into a can.
