Title: Methods of producing carbonimpregnated artefacts
IPC: C01B31/00
Filed: 1961-04-25
Abstract: A carbon-impregnated artefact is produced by arranging an artefact of open porosity at least 60% of its volume and low thermal conductivity in an atmosphere of hydrocarbon gas which permeates the artefact, heating an initial zone of the artefact to a temperature at which carbon is deposited from said hydrocarbon gas to impregnate substantially fully the initial zone with carbon, and then raising the temperature of the impregnated zone so as to maintain the deposition temperature within an advancing impregnated/non-impregnated boundary, the rate of rise of temperature in the initial zone being limited so that the zone defined by the advancing boundary is substantially fully impregnated with carbon. The artefact may be a carbon mass, e.g. a mass of carbon black particles or a carbonized cellulose fibrous material such as cotton wool, cotton, rayon, and cardboard, a mixture of carbon particles and a nuclear fuel material, which may be precoated with carbon, or a carbonized cellulose fibrous material having incorporated therein a nuclear fuel material. Both the mass of carbon and the mixtures of carbon with nuclear fuel material may be first compacted into coherent masses and granulated. The artefact may also be silica or alumina in which case the corresponding carbides may be formed, and the nuclear fuel material may also give rise to carbides. When the artefact has two opposed surfaces, the first of these surfaces is heated while hydrocarbon gas is supplied to the second surface, and as the temperature of the first surface is gradually raised the zone of deposition of carbon moves from the first surface towards the second surface. The artefact may be in the form of a tube, the inner surface of which may be heated, e.g. by a graphite heating element passing concentrically therethrough, either in contact or not with the inner surface of the tube, while the hydrocarbon gas is supplied to the outer surface, which may be cooled artificially. If the heating element is not in contact with the tube an inert gas, e.g. argon, may be passed through the annular space between the tube and the element. Alternatively the outer surface of the tube may be heated, hydrocarbon gas being supplied to the inner surface, in which case the inner surface may be cooled by a cooling fluid passing through a concentric inner tube. Suitable hydrocarbons are methane, which may be diluted with hydrogen, ethane, propane, butane, ethylene, propylene, butylene, benzene, and toluene. Specification 878,927 is referred to.
Patent ES-352656-A1 (ES)
Title: Thread clamping,releasing,and feeding mechanism for spinning apparatus
IPC: D01H4/48
Filed: 1968-04-10
Abstract: The draw-off rollers 312 of an open-end spinning device are arranged close to the end of the withdrawal tube 6 so that when the machine is stopped the yarn is held in the tube 6. The rollers are arranged to be separable so that the end may be drawn back into the spinning device. The rollers shrould be less than a third the length of the withdrawal tube from the opening of the withdrawal tube. As shown the rollers are preferably mounted on stub axles to facilitate threading up. A sensor may be situated in the withdrawal tube to stop the machine, including the draw off rollers, should the yarn break. In Fig. 3 not shown a yarn breakage detector in tube (6) causes a solenoid (32) to move the rollers apart and causes a further solenoid (36) to rotate a lever and thus allow a yarn reserve to be drawn back through the rollers. In Fig. 4 not shown, a solenoid (33) moves through a first distance to lift the draw-off rollers out of contact with their driving drum (310) and then through a further distance to separate the two rollers. The end of the withdrawal tube may be funnel shaped to facilitate the initial threading up of the device.

Title: Electrical interconnect device
IPC: H01R4/50
Filed: 1973-09-29
Abstract: Disclosed is an interconnect device for joining two conductors or connection terminals in a connection capable of carrying high currents. For example, the device may be used at terminal connections such as transformer, switchgear or busbars, and in fully insulatable systems for underground applications or enclosed vaults. The interconnect members comprising the device allow the connection to be made through the application of considerably less torque than is normally required to produce sufficient contact pressure for the connection. The main interconnect member has a lead screw with left and right threaded section. Jam nuts mounted on the screw are constrained to axial motion on rotation of the screw. The nuts have tapered surfaces to expand sections of a concentric sleeve on rotation of the lead screw in one direction, into conductive contact with the openings at the conductor or terminal lug, or with the bore of a member affixed to the connection terminal lug, or with the bore of a member affixed to the connection terminal. Rotation of the lead screw may be effected by the use of a suitable remote device, such as the well-known "hot-stick" in place of a wrench or other torque generating force. The interconnect device may also be disconnected readily, in a power-off condition by use of the same remote device.

Openings are provided for connecting the mixing chamber with the annular space, and escape pipes are provided for connecting the annular space with the reactor outlet. After optimal processing the reactants enter through the openings into the annular space and from there through the escape pipes to the reactor outlet.
Patent ES-449371-A1 (ES)
Title: Knitting apparatus
IPC: D04B27/10
Filed: 1976-06-30
Abstract: Decorative knitted fabrics have a basic weft knit structure with patterned effects produced by a warp yarn loops of which cover selected loops of weft yarn so as to be visible on the face of the fabric. The fabrics are produced by feeding warp yarns to selected needles of a straight bar knitting machine in addition to the normal weft yarn and controlling the tension of the yarn such that the warp yarn loops cover the corresponding weft yarn loops in the desired manner. To ensure the desired structure, it is preferred that the tension in the warp yarn should be relatively high when the yarn is wrapped round the selected needles but relatively low when the needles execute their knitting motion. Apparatus for producing these fabrics includes warp yarn guides which can be moved to and fro in front and behind the knitting needles and moved sideways past one or more needle positions. The warp guides can be swung upwards to clear the needles during fashioning movements. Warp tensioning means including a brake on the warp supply spool and a pair of cooperating bars or wires, moved in timed relationship with the knitting cycle, ensure that the correct tension sequence is observed.
