Title: Process for the Removal of Sulphur from Natural Gas and the like Gases
IPC: B01D53/48
Filed: 1967-11-08
Abstract: Sulphur compounds are removed from natural and like gases by continuously flowing the gas, preferably after admixture of hydrogen and/or steam, in contact with active iron cobalt or nickel suitably prepared by reducing a coprecipitated nickel-alumina catalyst. The active metal bed is generally maintained at 250-400 C., and, although the active metal is a catalyst for the decomposition of the methane present in the gas, the process is operated under such conditions that the methane is substantially unaffected. The gas to be treated generally contains no more than 6%, preferably no more than 3%, ethane or equivalent hydrocarbons higher than methane and is brought into contact with the active metal at not higher than 350 C. in admixture with up to 0À1 vol. steam/vol. gas. As exemplified, the sulphur compound is tetrahydrothiophene.

Title: Hydrodynamic brake and regulating means therefor
IPC: F16D57/04
Filed: 1968-01-04
Abstract: In a hydrodynamic brake, having a stator 21 (Fig. 2) and a rotor 22 fixed to a shaft 23 to be retarded, the fluid outlet 31 from an annular channel 29, connected to the main brake chamber by a radial gap, is constructed to give a particular relationship between the flow rates into and out from the brake housing and hence the degree of filling of the brake whereby to provide a desired braking torque characteristic as a function of rotor speed. The brake is supplied with fluid by a pump 26 from a reservoir 25 and fluid is fed back to the reservoir from the outlet via a slide valve 33. The fluid may also be circulated through a heat exchanger (not shown). A valve 28 serves to activate the brake and has no regulating function. A preferred arrangement of the outlet is shown in Figs. 3a, 3b and includes a wall piece 35 which may be integrally formed with the annular channel wall e.g. by moulding, or alternatively may comprise a flexible baffle plate provided with an adjustment screw. In Figs. 4a, 4b (not shown) the annular channel has a reduced cross-sectional area (Venturi) in the vicinity of the outlet while in Figs. 5a, 5b (not shown), the end of the outlet pipe line 32 protrudes into the channel and is shaped to act as a "scoop" the orifice being positioned to face the direction of flow and the pipe line end may be rotatable. In Figs. 6a, 6b (not shown), the angle at which the pipe line meets the channel wall is selected according to the required torque/speed characteristic.

Title: Yarn assembly apparatus for false twisting yarn
IPC: D02G1/02
Filed: 1968-05-07
Abstract: In yarn treatment comprising separating a two-ply multi-filament yarn into its constituent plies, resistance to the upstream movement of the twist is imposed at a plurality of upstream points, whereby the degree of twist is progressively decreased from full twist at the most downstream of said points to substantially zero at the most upstream of said points. As described, said treatment relates to yarn crimping as described in Specification 1187532, in which two multi-filament yarns 12, 13, Fig. 5, pass in substantially flat, untwisted formation through a first groove 31 formed in a heated body 30, the twist, pre-imparted to the yarns, develops progressively in stages as the yarns engage successive points on a series of rollers, pins or guides, the twisted yarn 18 passes through a second groove 32 in body 30, the heated yarn is cooled to set the twist, and the constituent crimped yarns are then separated and are wound on respective take-up rollers. In Fig. 5, the untwisted yarns engage a point 294 on a fixed, larged-diameter pin 94, whereafter the twist begins to develop. The yarns then pass around a small-diameter pin 95 adjustably fixed in a slot 96, and finally engage pin 94 at a point 194 diametrically opposite point 294, whereafter the fully-twisted yarn passes to groove 32. In Fig. 3 the untwisted yarns pass downwards through a crotch between an upper freely-journalled roller 81 and a lower freely-journalled roller 82 disposed at right angles to roller 81, and ascend through the opposed crotch between the rollers. Twisting commences at the first point of contact 187 on roller 81, and is completed after the final and diametrically opposite point of contact 184 on roller 81. In Fig. 7, the yarns pass in succession through a guide 108, over a tension wheel 107, through a guide 106, and around a pair of pins 101, 102 carried in diametrical opposition by a pivotal disc 103 secured in adjusted angular position by a thumb nut 105, the yarns changing in direction after each point of engagement.

Title: Apparatus for marking conductor cables
IPC: H01B13/34
Filed: 1970-04-23
Abstract: A longitudinally advancing conductor cable freshly extruded with plastic insulation is marked by a stream of a fluid material of a predetermined color as follows: The stream is first ejected from a high-pressure nozzle, sinusoidally deflected by electrical deflection means, and then the deflection is amplified to be substantially larger than the cross-sectional dimension of the cable by an electrical amplifying means before the stream is applied transversely to the cable. Where a complete band mark needs to be made around the cable, a second stream may be applied to the cable opposite to the side being marked by the first stream, by deflecting and amplifying the second stream in the same manner as the first stream. Using a displacement electrode and varying the DC potential applied thereto, the band marks made by each stream may be matched more precisely by bending the second stream toward the advancing direction of the cable and by controlling the degree of bending to match the first stream as the two streams hit the cable. A plurality of streams of different or the same color materials may be applied to the cable simultaneously at given intervals after being deflected and amplified in the same manner as the first stream.

Title: Method of producing molded bodies of expanded plastic
IPC: B29C45/16
Filed: 1979-09-12
Abstract: The invention relates to a method of producing molded bodies of expanded plastic having a predetermined density, based on a starting material in granulate form to which a blowing agent and optionally a cross-linking agent have been added, said starting material being introduced into an injection molding machine/press in which it is heated and injected/pressed into a mold. In order to obtain an efficient production process without loss of raw material and a product whose density can be determined in advance, the material in the injection molding machine/press is heated to a temperature which is below the temperature required to initiate the reaction of the blowing agent/cross-linking agent, and the blank thus formed is subsequently transferred to an expansion mold having the shape of the desired final product, but larger, than the blank. The blank is caused to expand in the expansion mold and final expansion takes place outside the expansion mold. One is thus permitted to operate with a lower pressure than required previously.
