Title: Method for finding shapes of bodies with good fluid dynamic properties
Inventor: O'REILLY EDGAR
IPC: B62D35/00
Filed: 1984-11-12
Abstract: In order better to find shapes of bodies with good fluid dynamic properties or to find the corrections required on given shapes, in particular car bodies, the said bodies are examined in a wind tunnel. According to the invention, at the same time, small ice crystals or other powder or chip-like solid particles are also let into the airstream and then settle at points of reduced flow speed on the body of the car. These typical deposits are areas where air vortices are occurring which previously could only be found in a very complicated fashion. The method can also be used in the opposite manner in that ice crystals or other solid particles are placed in a layer over the object to be investigated, which is subjected to the airstream in the wind tunnel. The solid particles which are subjected to a lower flow speed remain adhering to the object. This method also applies in an analagous fashion to a fluid.

Title: Screwdriving tool
Inventor: CERUTTI CESARE
IPC: B25B17/00
Filed: 1985-03-23
Abstract: A screwdriving tool (1) is provided with a handle (2) and a tool part (21) which has an end section (38) which acts on parts to be screwed in. The axis of the end section (38) runs essentially at right angles to the longitudinal axis of the handle (2). So that both high and low torques can be applied with the screwdriving tool (1) in the smallest possible space and working area, the screwdriving tool (1) can be operated in two positions. In the first operating postion, the handle (2) forms a fixed block with the tool part (21) and is moved in such a way that the screwdriving tool (1) rotates about the axis of the end section (38). In the second operating position, the handle (2) remains spatially fixed, and, when the handle (2) is rotated about its longitudinal axis, the first end section (38) rotates about its axis orthogonal thereto. <IMAGE>

Title: Wind power stations and motors
Inventor: SCHMOLS KARL-HEINZ
IPC: F03D7/02
Filed: 1985-04-17
Abstract: The wind rollers can be correspondingly formed in order to create free space in the middle of wind power stations. The counter weights and other devices are to be shifted outwards by means of one or two pairs of arms, which are fixed in or below the oscillation point. The arms rotate with the station and are supported by rolling or floating devices. For the compressors, gas pressure or combustion engines, for each motor unit, except for the main motor, crankshafts fixed on the motor block are arranged and connected to the drive shaft of the motor by connecting and pushrods. In the case of a plurality of motors the crank discs or crank arms of the crankshafts are also synchronously connected. The force can be taken off from both ends of the crankshaft axis. Both motors have chambers which are used for cooling of the motors. These chambers can be used for the intake and compression of fuel mixtures and these fed through ducts and valves to the combustion chambers.

Title: Device for intrauterine cell sampling
Inventor: HAMMANS WILHELM DR MED
IPC: A61B10/00
Filed: 1985-11-07
Abstract: Device for intrauterine cell sampling, especially for screening tests for endometrial carcinoma, comprising an applicator rod, an applicator sleeve and a specimen probe. The applicator rod, which projects beyond the applicator sleeve on the operating side, is manually displaceable in the applicator sleeve. As a result, the specimen probe connected to the applicator rod can be moved into and out of the applicator sleeve. On leaving the applicator sleeve the specimen probe has spreading probe elements. In the spread state the specimen probe forms a closed frame with V-shaped spread probe elements connected to the applicator rod and, connected to said elements via lateral tube angle arch parts, roof-shaped probe elements which are joined via a fundus arch. In a region in front of the specimen probe the applicator rod is provided with a piston which is sealingly guided in the applicator sleeve as the associated barrel. When the specimen probe is moved in, the piston acts as a suction piston. Cell material picked up by the specimen probe is sucked from the upper edge of the applicator sleeve via a suction gap into the applicator sleeve. <IMAGE>

Title: Apparatus for regulating the transport speed of a fibre tow or the like by means of a jockey roller
IPC: B65H59/38
Filed: 1985-12-21
Abstract: The movement of jockey rollers for regulating the transport speed of an endless material in order to keep a predetermined tensile stress in this material constant is conventionally influenced by pneumatically generated weight loading and by hydraulic damping. In order to avoid any uncontrolled movements of the jockey roller in the event of extremely high tensile stresses, according to the invention the entire control of the movement of the jockey roller is regulated hydraulically, for which purpose a hydraulic pump driven by an electric motor supplies a control unit having a number of hydraulic valves continuously with the hydraulic fluid, as a result of which all changes in the loading and the movement processes on the jockey roller are possible, even during operation. <IMAGE>

Patent DE-3604140-A1 (DE)
Title: Embroidering machine
Inventor: WALLIMANN HANS
IPC: D05C11/10
Filed: 1986-02-10
Abstract: The embroidering machine comprises at least one row of embroidering needles (2) which are arranged in a relatively large number and the embroidering yarns (3) of which partially loop round thread guides (6, 6') of a yarn-delivery device (4) which oscillate to and fro and which jointly lie next to one another for the yarn feed and the yarn return, respectively. Arranged in the region of the thread guides (6, 6') or on these are elastic thread-guiding members (11) which limit a lateral displacement of the embroidering yarns (3) on the thread guides. This makes it possible effectively to limit a lateral displacement of the embroidering yarns on the thread guides, without thereby impairing the manual draw-in of the yarns in the region of the thread guides after a thread break and with the machine running, and without appreciably increasing the effective mass forces on the thread guides. <IMAGE>

Abstract: For an indirectly emitting light, in particular for high-pressure discharge lamps, which light is formed from a housing (10) with upwardly directed light exit opening (13) and from a reflector (16) which is arranged in the housing (10) and surrounds the lamp (15), a device (7) for direct downward emission of light is to be provided. The said device (7) consists of a base-side reflector cut-out (17) and a base cut-out (18) located therebelow on the light housing (10) and of a reflector component (22) which is directed obliquely with respect to the lamp (15) in relation to the base-side reflector plane (16) and is arranged above the reflector cut-out (17) and is constructed in a reflecting fashion on the base side (reflector surface 23). In addition, the device (7) comprises, for the purpose of the direct emission of light between the base-side reflector component (16) and the housing base (11, 20) an adjustment plate (24) for changing the cross-section of the exit of the reflector cut-out (17). Thus, a fraction of the light (6) emitted by the lamp (15) can be emitted downwards through the base cut-out (18), it being possible for the cross-section of the exit to be varied by means of through-openings (30 to 33) which have cross-sections of different sizes and are provided in the adjustment plate (24) (Fig. 2). <IMAGE>
