IPC: B63H23/00
Filed: 1963-04-11
Abstract: 999,319. Power plant; driving gear. DAIMLER-BENZ A.G. April 11, 1963, No. 14642/63. Headings F1B and F1Q. [Also in Division F2] Two engines 11, 12, are connected to a single drive shaft 15 through hydrodynamic couplings 13, 13<SP>1</SP>, which have inclined blading 18, 22, Fig. 2, permitting the couplings to act as freewheels. The blades 18, 22, are inclined in the forward direction of rotation so that the torque transmitted is large in the forward direction (arrow 20) but is small when the driven member 17 overruns the drive member 16. The hydraulic clutch comprises a primary bowl 16 on the drive shaft 31 and a secondary bowl 17 on the driven shaft 32. A loose ring 34 controlling the operation of valves 27 controlling the emptying of the coupling, is mounted on a stub 35 of shaft 31 with limited lost motion 37, Fig. 5, and is in frictional contact with the shaft 32. When the shaft 31 starts driving shaft 32, valve 34 is rotated relatively to shaft 32, within the limits of lost motion slot 37, to the position of Fig. 5 in which a port 41 is out of register with a port 40 and the supply of compressed fluid from pipe 44 is cut off from passages 30, 29, leading to spring loaded valves 27 closing the coupling emptying ports 26 in the rim of the rotor. When shaft 32 overruns shaft 31, the ring 34 is rotated by friction to the portion in which port 40 is in line with passages 43, 40, whereby fluid is supplied to passages 29 to open the valves 27 and empty the coupling through ports 26. Alternatively overrunning of the shaft 31 by shaft 32 may bring about disconnection of a mechanical clutch disposed between the hydrodynamic coupling and the driven system.

Patent GB-1261612-A (GB)
Title: Process for producing differential dyeing and crimp properties in yarns of thermoplastic materials
IPC: D02J1/22
Filed: 1969-03-21
Abstract: 1,261,612. Non-uniform treatment of yarns. TEIJIN Ltd. 21 March, 1969 [23 March, 1968 ; 23 Oct., 1968; 8 Feb., 1969], No. 15132/69. Heading B5B. [Also in Division D1] An inert liquid is applied non-uniformly to a yarn of a thermoplastic material, and the yarn is then given a high temperature heat treatment in which it is heated without making contact with any solid surface to a temperature above the melting point of the yarn for a time such that the dyeability of the parts of the yarn to which the liquid has been applied is increased, while that of the other parts is unchanged or increased to a smaller degree, without weakening the yarn to a degree such that it cannot withstand conventional textile operations. The invention also comprises the non-uniform application of an inert liquid to a previously crimped yarn, or to a composite yarn possessing latent crimpability, followed by a heat-treatment as above such that the crimp or latent crimpability is reduced or eliminated in those parts of the yarn to which theliquid has not been applied, but not, or not to the same extent, in those parts to which it has, without weakening the yarn to the degree indicated above. Yarns treated by any of the above processes, which yarns will usually be multi-filament yarns or filament bundles, may subsequently be dyed. In the high temperature heat-treatment of latently crimpable yarn, the yarn is suitably held under sufficient tension to prevent a crimp developing at that stage. The treatment of polyamide and polyester yarns is exemplified. Water is the preferred inert liquid by virtue of its high latent heat and specific heat, but carbon tetrachloride and liquid paraffin are also used.  By non-uniform application is meant that the liquid is applied locally over parts only of the yarn surface, so that areas carrying the liquid alternate with areas free from the liquid, either along the length of the yarn or round its circumference or both. In the apparatus of Fig. 1, a yarn 1 is forwarded by feed rollers 2, passed through a heating device 4 via a liquid supply roller 3 and withdrawn, via take-up rollers 5, by a wind-up roller 6. The liquid may be applied to the yarn intermittently along its length by means of a roller or rollers 3, provided with teeth at regular or irregular intervals about its periphery, at least the tooth portions thereof being immersed in liquid stored in the bath 3<SP>1</SP>. By using two or more liquid supply rollers, various liquid application patterns may be produced on the yarn. Figs. 3 and 4 (not reproduced) show other liquid application devices. Fig. 2 shows the heating device. A stream of a gaseous medium at the required high temperature is passed through the chamber 4, so that the yarn does not make contact with any solid surface.
