Title: Improvements in fuel tank ventilation in motor vehicles
IPC: B60K15/035
Filed: 1970-11-09
Abstract: 1283274 Venting fuel tanks FIAT SpA 9 Nov 1970 [14 Nov 1969] 53108/70 Heading B8X [Also in Division F1] Motor vehicle has a fuel tank having a number of spaced apart holes in its upper surface, a tube leading from each hole to a vapour trap which is purged by air which is subsequently fed to the engine, a normally closed valve which controls communication between the tank and atmosphere and at each hole a further valve controlling the flow through the tube leading from that hole, the said further valve permitting the flow of vapour, but not liquid from the tank. The tank 2 has a hole at each end controlled by a valve 8 connected by a tube 44, 45 to a manifold 52, and hence by a tube 51 to a vapour trap 46 containing e.g. activated carbon. The trap is purged by air drawn through a filter 48 and then led to the intake manifold of the carburetter 7. Each valve 8 comprises a chamber 10 connected to the tank by a pipe 19 which enters the chamber at a low level and by a second pipe from a further hole in the tank which enters the chamber at a higher level 21. The chamber is closed by a bolted-on lid 12 having a passage 26 which intersects a threaded bore 27. A spigot pipe 43 projects from the passage 26 and a tubular member 29 is screwed into the bore 27. A conically-ended closure member 35 slides in the bore of member 29 and engages a shoulder in the bore to prevent flow therethrough. A lever comprising upper and lower arms 41 and 42 respectively is pivoted on a pin 39 and has a float secured to the lower arm 42. The upper arm is connected to the closure member 35. Vapour can pass freely through the chamber and leave by the passage 26, but the float rises and closes the outlet if liquid enters the chamber 10 due to the motion of the vehicle or damage to the tank.

In apparatus for detecting the presence of flaws in elongate magnetizable test material of circular cross-section, the material is advanced spirally between the poles of an alternating current electromagnet and any flux leaking from the surface of the test material due to a flaw is detected by two Hall plates disposed in the same plane close to the surface of the test material and symmetrically with respect to the magnetic centre axis between said poles, the Hall plates being connected in an electric circuit so arranged that noise commonly detected by the Hall plates is substantially cancelled. The Hall plates may be arranged in line parallel to the axis of the test material, but preferably a line through the centres of the Hall plates makes an angle of 5 degrees with the axis of the test material. The positions of the Hall plates may be adjustable by screws. The frequency of the alternating magnetic field is in the range 50 to 1000 c/s.

Title: Process for producing fleeces or mats from short fibres
IPC: D21F9/04
Filed: 1972-11-29
Abstract: 1419392 Making fibrous webs MESSERSCHMITT-BOLKOW-BLOHM GmbH 29 Nov 1972 [22 Dec 1971] 55188/72 Heading D2A  Fleeces having unidirectional short fibres are produced by depositing a liquid suspension of fibres on a carrier provided on a drum, the carrier being subjected to a flow of the suspension initiated by allowing the suspension to flow into a collecting vessel with the carrier on the drum being immersed in the collected suspension and moved continuously therethrough by rotation of the drum, the fibres being deposited on the carrier during repeated rotation of the drum, the carrier and fleece thereon being then removed from the drum. The carrier may be an endless band. As shown in Figure 1, an agitating unit 1 contains suspension 2, e.g. of glycerine and reinforcement fibres. A channel 3 with a valve 4 connects unit 1 with collecting vessel 7 of a drum filter 5 consisting of drum 6 rotatably mounted on vessel 7 and driven by an electric motor in the direction shown by arrow 9. The suspension 2 falls into collecting vessel 7 via channel 3, the base 23 of the vessel being in the form of a trough the base of the trough having a curvature conforming to that of the drum 6. The fibres contained in the suspension in the passage of the drum surface through the bath 10 formed in the channel 7 supplemented by the flow of the suspension 2 deposit themselves on the surface of the drum 6 as an even layer 11 which increases in thickness on each rotation of the drum 6. The adhesion of the fibres to the outer surface of the drum is ensured by a falling pressure gradient of air between the exterior of the drum and the interior. For this purpose the casing of the drum consists of a fine-mesh net structure 12 which before starting up is coated with a permeable filter foil 13 of paper, textile or synthetic plastics acting as the carrier. A pipe is introduced into the interior of the drum through an air-tight mount, the end of the pipe being bent downwards so that through the suction effect liquid in the trough 23 penetrating the outer casing of the drum is sucked off, and a cavity with rarified air is created in the interior of the drum so that the fibres deposited on the casing of the drum adhere firmly thereto. The layer of fibres 11 may be cleansed by spraying a cleansing liquid from spray pipe 21 provided with spray apertures, the valve 4 having been closed. The resulting fleece is detached from drum 6 by cutting in the direction of the axis of the drum and then dried, the foil 13 serving as the carrier. The fibres are then fixed with a suitable solution.

Title: Method and apparatus for the production of Fuel and/or Breeder Elements for Nuclear Reactors
IPC: G21C21/02
Filed: 1966-12-13
Abstract: 1,170,740. Fuel elements. KERNFORSCHUNGSANLAGE JULICH G.m.b.H. 13 Dec., 1966 [16 Dec., 1965], No. 55725/66. Heading G6C. A fuel element in which the fuel material is disposed in a chamber between an outer spherical casing formed of carbon, more particularly hard carbon, graphite, ceramic material, or sintered metal and a core body, is formed by applying a filler body shellwise to the core body by spraying-on or casting of a material which is readily removable thermally, chemically or mechanically, applying the casing to the filler body, removing the filler body, introducing fuel material into the resulting chamber between the casing and the core body, and sealing the casing. A synthetic plastics material such as polyethylene, or a metal may be used for the filler body. It is expedient in some cases to make the core body and the casing from the same material. At least two diametrally oppositely situated and radially directed pins, the lengths of which extend through the casing, may be arranged on the core body. During the step which follows the spraying-on or casting of the filler body on to the core body, and wherein the casing is expediently applied by pressing, these pins serve to centre the core body in the press apparatus. If graphite powder, mixed with phenol resin, pitch and/or other binding agent, is used for the casing and the core body, a spherical core body is first pressed at a pressure of 1500 to 2000 kg/cm.<SP>2</SP> The press tools are kept at about 250‹ C. so as to obviate arranging the hexagonally built-up graphite crystals in such a manner that in the finished mouldings zones are formed in the equatorial region which have an irregular orientation, so-called pressure wedges. If the filler body is of polyethylene or metal, the member formed of the core body and the filler body is held at about 1250‹ C. after the pressing-on of the casing for a period of some weeks. The filler body melts and frees the desired chamber, also the phenol resin used as a binder is coked. In a further stage, the body intended for accommodating the fuel material is heated for graphitization in an electric furnace at 2500‹ to 3000‹ C.

In a viscously-damped elastically-tuned inertia-mass damper for a rotating shaft, a hub 10 co-operates with a cover 12 to define an annular chamber containing the mass or masses 24. The or each mass is bonded to an elastic, e.g. rubber, element 46 which in turn is bonded either to the hub or to the cover, but not both.
