Title: Fibre feed duct for friction spinner - turns fibres suspended in air stream to be parallel to one of friction surfaces on which they are then deposited
Inventor: DERICHS JOSEF DR ING
IPC: D01H4/16
Filed: 1992-11-26
Abstract: A friction spinning device has two friction elements (11,15) which interact internally to form a friction slot (16). A fibre opening arrangement (2) places fibres in an air stream which transports them to the friction surface. The fibre channel (4) is designed so that single fibres (8) which are initially drawn out in the direction of transport (T) are arranged parallel to the perforated depositing surface (10) of a friction element (11). The depositing surface (14) is subject to suction from the outside of the perforated surface (10) and is at a distance from the friction slot (16). The friction element (11) with its depositing surface (10) is rotated by a drive (20) at a high enough speed for individual fibres (8') emerging from the fibre channel (4) to be deposited virtually singly onto the friction surface (10) and taken to the friction slot (16). USE/ADVANTAGE - Improved friction spinning fibre feed duct. Fibres are turned in the feed duct and are deposited in the optimum position for yarn formation.
Patent DE-4303208-A1 (DE)
Inventor: KELLER PAUL
IPC: E02F9/10
Filed: 1993-02-04
Abstract: A device (10) for perpendicularly aligning the upright axis (9) of a superstructure (7) turnably and inclinably mounted on an understructure (11), for example a turntable ladder (12), is proposed, which has an upper turntable (8) and a lower turntable (2), a tilting mechanism (1) with a central swivelling axis (13) and associated tilting drive in the form of hydraulic control cylinders (6) being interposed. Instead of the tilting mechanism, one or more control cylinders (17) can be directly interposed between the upper and the lower turntable, it being possible to displace the upper and lower turntables on two oblique paths or inclines (18, 19). The lower turntable (2) can be replaced by a ball-bearing slewing rim (14) with associated parking brake (15), which in terms of tactics of use is of great advantage. The power flow then no longer takes place via two toothings but only via a rotary drive and a turntable. <IMAGE>

Title: Device for applying tensile forces
Inventor: FUCHS GERALD
IPC: B25J9/10
Filed: 1993-03-18
Abstract: It is already known to produce tensile forces by a pressure medium, such as air or oil, by pistons movable in cylinders. However, these devices have the disadvantage that the force increases slowly, since the full pressure first has to be achieved before the piston moves. With the device according to the invention, the force is to increase directly upon the admission of pressure. This is achieved in that at least one band-shaped or rope-shaped tension element (4 to 11) is arranged in the longitudinal direction of the bellows (2), and that the tension elements (4 to 11) present extend at least from one end (12) of the bellows (2) up to an opposite end (13) of the bellows (2) and are fastened to the bellows (2) in such a way that, when pressure is admitted to the bellows (2), the extension of the bellows (2) is effected only in its transverse direction. <IMAGE>

Title: Method for producing a semiconductor laser diode generating visible light
Inventor: KADOIWA KAORU
IPC: H01S5/00
Filed: 1994-04-07
Abstract: A method is disclosed for producing a semiconductor laser diode generating visible light, in which, after growing a p-type GaAs contact layer on a p-type AlGaInP plating layer, an n-type layer is formed by growth on the p-type GaAs contact layer, which n-type layer contains a semiconductor material which is selectively etched with an etching agent which does not etch GaAs. After cooling of the wafer, the n-type layer is selectively etched off. In this method, a diffusion potential appearing at the p-n junction between the p-type GaAs contact layer and the n-type layer prevents hydrogen radicals from penetrating into the p-type AlGaInP plating layer during the cooling of the wafer, as a result of which the activation ratio of Zn atoms in the p-type AlGaInP plating layer is increased. A semiconductor laser diode, which generates visible light, with reduced threshold current and improved temperature properties will therefore be obtained even if the Zn/III ratio during the growth of the p-type AlGaInP plating layer is low. Since the n-type layer grown on the p-type GaAs contact layer contains a semiconductor material which is selectively etched with an etching agent which does not etch GaAs, the additional result is obtained that the etching process of the n-type layer can be carried out with good controllability and without detrimental influences on the surface of the p-type GaAs contact layer, by means of which a visible-light generating ...

Title: Process and device for screwing tubular sleeves
Inventor: KUBIK F
IPC: B23P19/06
Filed: 1979-03-02
Abstract: Process and device for connecting in a tight manner the end of a pipe presenting a cone thread to a corresponding tubular sleeve and subjected to high torques. The holding forces generated by the clamp chucks create some deformations in the pipe which make a tight screwing more difficult. Further, the speed changes of the massive clamp chucks require slow rhythm of work and drive powers which are not compatible with a rational mounting system. The invention provides for a two-step process, wherein an auxiliary spindle (19, 20) is screwed into the sleeve (14) which will be screwed to the extremity of the pipe (5) by means of said spindle (19, 20). This auxiliary spindle (19, 20) is then removed and the end of the pipe (5) and the sleeve (14) are further tightened one against the other under high torque by two rotating clamp chucks (2, 9). The clamp chucks are disposed in such a manner that they allow eccentric and angle variations to take up the mounting tolerances of the pipe sections (5, 14). The clamp flanges (26) are hydraulically operated and hold the pipe sections (5, 14) substantially around the whole contour thereof. The device is preferably used for the preassembly at the factory of pipes aimed at being engaged in oil-well drillings.
