Title: Cage for radial ball bearing
Inventor: FLANDER HANS ING GRAD
IPC: F16C33/38
Filed: 1983-03-05
Abstract: The invention creates a flange-mounted cage for radial ball bearings, which is suitable for high speeds, possesses great stability for a low weight and facilitates optimum lubrication in the bearing. The cage comprises a body essentially located outside the bearing pitch circle, which body undertakes radial guiding of the cage, and two ribs projecting radially over the pitch circle for guiding the balls. The contact between the balls and the ball pockets of the cage occurs only in precisely defined angular ranges. The cage according to the invention permits optimum lubrication of the raceways, the admission of lubricant to the poles of the balls being unimpeded, lubricant being fed to the raceway edges and to the tracks of the races and the highly stressed track on the balls being relieved of the frictional load on the cage. Since it is intended for high-speed bearings, the cage is flange-mounted.

Patent DE-3320321-A1 (DE)
Title: Diaphragm supporting framework of cloth or sheet or a combination of both which is used as a sail on ships
Inventor: MENZ WOLFGANG DIPL ING
IPC: B63H9/06
Filed: 1983-06-04
Abstract: The hitherto known embodiments for diaphragm sail surfaces all suffered from aerodynamic disadvantages due to seam layers across the flow direction or a material thickness or rigidity not adapted to the lines of force in the diaphragm surface. In some cases, it was previously attempted to obtain the absence of rigidity by very expensive doubling-up in the leech area. These disadvantages are largely eliminated by the embodiment of the diaphragm surface now available. In the leading area of the sail, the seams lie virtually in the direction of the oncoming flow, while webs which are more rigid and which can be stressed to a greater degree run parallel to the leech in the leech area, which is stressed by forces to a greater degree.

Patent DE-3334191-A1 (DE)
Title: Process for the finishing of textile sheet-like structures
Inventor: REIM INGEBORG
IPC: D04H11/08
Filed: 1983-09-22
Abstract: The invention relates to a process for the finishing of textile sheet-like structures, by means of which textile sheet-like structures for outer clothing, upholstered furniture covers and car-seat covers as well as for decoration, preferably consisting of yarns in the range of yarn linear density typical of woollen yarn, and/or of worsted yarns (for example, ring yarns, open-end yarns, MJS yarns, friction yarns), can be adjusted "to size" by the sheet-forming process. The object is achieved in that textile sheet-like structures are fed alone or together with the most diverse sheet-like structures (for example, nonwoven, fabric, foam material, etc.), but also thread groups, to a needling process. As a result of the needling process, in which the fibres are displaced from one layer into the other with 50 to 1200 stitches per cm<2> felting needles, preferably CB notched needles, a permanent layering is obtained, but this can also be cut in order to produce sheet-like structures with pile.
Patent DE-3340459-A1 (DE)
Title: Process and apparatus for determining the frictional behaviour of elongate structures, especially of yarns
Inventor: UNTERREINER JOSEF DIPL ING
IPC: G01N19/02
Filed: 1983-11-09
Abstract: In the process, the running yarn is subjected to an adjustable normal force, the tensile force caused by this force is determined, and the difference between the running speeds before and after the loading is ascertained, and this is converted into electrical quantities which define the normal force, the tensile force and the stretching of the yarn. The apparatus contains a motor control part (20) for controlling a motor (22) in order to draw off the yarn, a yarn-tension measuring device (8), by means of which the normal force is applied and the tensile force is determined, and a yarn-stretch measuring device (23), by means of which the difference between the running speeds is ascertained. The running speed, tensile force, normal force and stretching are indicated in indicator units (27-29). So that the difference between the running speeds, which is a measure of the stretching, can be indicated over the entire range of rotation, for example a 20-step control switch (24) having three potentiometers (R1 R2 R3) is provided. The initial resistance values of those devices ascertaining the running speeds before and after the loading are thus matched to the regulating resistance value of the motor speed. <IMAGE>

Patent DE-3404368-A1 (DE)
Title: Labelling device
Inventor: WINTER HORST
IPC: B65C9/36
Filed: 1984-02-08
Abstract: In a labelling device with removal elements (9) which circulate on a circular path and have glueable adhesive surfaces (11); with transfer elements (10) which circulate on a circular path and have gripper fingers (15); with a stationary label container (7); and with a rotating glueing roller (4), the removal elements and the transfer elements are movably arranged on a common rotor (3). Each unit, which is fastened onto a shaft (8) which is rotatably mounted in the rotor, comprises one transfer element and one removal element. The shafts are driven in an oscillating fashion in such a way that the adhesive surfaces roll off onto the glueing roller and the labels (1) in the label container and the removed labels are subsequently transferred from the removal elements to the transfer elements running upstream. In the transfer region, the transfer elements point radially outwards and press the labels onto the objects to be labelled. Only a single rotor is therefore required, which permits a compact and simple design. <IMAGE>
Patent DE-3405002-A1 (DE)
Title: Starting protection for an asynchronous rotating-field machine
Inventor: MAIER FRANZ DIPL ING DR
IPC: H02H7/08
Filed: 1984-02-13
Abstract: The starting protection of a rotating asynchronous rotating-field machine (1) has a current transformer (4), a voltage converter (5), a device for producing a speed-dependent variable from the values of the current (I) and of the supply voltage (U) detected by the current transformer (4) and voltage converter (5), as well as a control device. This control device is used for continuously testing the speed-dependent variable and, in the event of a value of the speed-dependent variable, which value signals that the machine has started within a starting time (tA') remaining absent, produces a command to switch the machine (1) off. This starting protection is intended to enable reliable monitoring of the entire starting phase in a simple manner. This is achieved in that the control device, which is constructed as a controlling and computing mechanism (9) having an associated memory (10), detects the real current (Iw) of the machine (1) as a speed-dependent variable, forms the differential real current ( DELTA Iw) from this and, when the starting of the machine (1) has been achieved, produces a suppression signal which results when the mathematical sign of the differential real current ( DELTA Iw) changes. <IMAGE>

Title: Device for stereoscopic image reproduction
Inventor: MAZANDER KLAUS-DIETER DR
IPC: G03B35/24
Filed: 1984-03-13
Abstract: In order to produce a stereoscopic effect, in particular in television sets and/or other image generators equipped or not equipped with cathode-ray tubes, a template is applied to the screen (or an equivalent device). Light channels of a specific degree of inclination in the template direct the light of the individual pixels of different images in different directions, optical separation of the simultaneously transmitted images being performed. The images respectively show the same subject at different angles (corresponding to the human interocular distance). The images can be seen in a defined range of distances from the screen and at a defined viewing angle which encompasses the entire size of the screen. By changing his position in the horizontal plane, the viewer can then respectively see another image or the image which analogously comes next. If he adopts an intermediate position, in which each eye sees a different image, he has a stereoscopic impression.

Patent DE-3427723-A1 (DE)
Title: Track-bound vehicle with steerable wheel sets
Inventor: BUGARCIC HELMUT PROF DR ING
IPC: B61F5/44
Filed: 1984-07-27
Abstract: The invention relates to a track-bound vehicle, for example rail vehicle for use in towns, having steerable wheel sets. In known bogie vehicles of the aforesaid type, a radial adjustment of the entire steerable wheel set takes place when going round a bend. In this process, the steering takes place by means of a lever mechanism which transmits the deflection of the bogies with respect to the waggon body to the wheel sets. In the subject of the application, intermediate wheel hub rings (3) are attached on each side of a fixed wheel set axle (2) in such a way that they can be swivelled about the vertical together with the respective wheel which is mounted on the intermediate wheel hub ring by means of roller bearings (10). Here, the leading axle line is located perpendicular to the carriageway and coincides with the respective contact point of the wheel. The tangential adjustment of the wheel with respect to the longitudinal edge of the rail takes place in the bend in the track, is controlled by a central computer or similar and steering takes place by means of mechanical, electrical or pneumatic actuation elements. The two wheels of a wheel set are connected to one another via a hollow shaft (16), the power take-off and the drive being brought about therewith. At the same time, the conventional bogie drives can be taken over in unchanged form. Thus, with a simplified design, the actuation forces and the wear are considerably reduced, squeaking when going round a bend is completely eliminated and a kinematically satisfactory travel around the bend is achieved. <IMAGE>
