Title: Compact electrical stepping switch
Inventor: KIEFNER HERMANN
IPC: H01H1/58
Filed: 1986-04-05
Abstract: The stepping switch, which is provided with a latching mechanism (5), has at least one stator core (1) to which at least two contact carriers (2) belong which are located one above the other and each of which combines a plurality of stationary contacts (3) of a contact plane in an insulating body (21). The stationary contacts (3) are constructed on the radial inner side of the contact carriers (2) as contact tongues (31) and are arranged on a circular arc. A round switching positioner (4) is supported between the contact carriers (2). This round switching positioner (4) carries at least one contact link (10) which is used for the purpose of connecting at least one stationary contact (3) of one of the contact carriers (2a) to at least one stationary contact (3), which is located above it, on the other contact carrier (2b). A particularly simple and maintenance-friendly construction is achieved in that the external diameter (A) of the round switching positioner (4) is equal to or less than the diameter (B) of the circular arc which is formed by the free ends of the contact tongues (31). A retaining ring (7) which is supported by the stator core (1) of the stepping switch surrounds the switching positioner (4) in a centring manner and creates a connection for it, which connection holds it such that it can rotate on the stator core (1). <IMAGE>

Title: Apparatus for comminuting glass bottles intended for a bottle bank
Inventor: PETER HEINRICH
Filed: 1986-09-04
Abstract: The apparatus according to the invention, for comminuting glass bottles intended for a bottle bank, comprises a tube (10) which is installed horizontally in a bottle bank. The front end tube opening (10b) is accessible from outside, while the rear end opening is closed. Formed at the bottom of the tube are openings (10a) through which the fragments of the glass bottles can fall. By means of a hand-actuated lifting mechanism, a bar (12b), which is held above the tube and on which there is fastened a plurality of striking bolts (15) which project radially into the tube, is raised up counter to the pressure of springs (14) to such an extent that the striking bolts unblock the interior of the tube. The spring forces are released by means of a hand-actuated trigger mechanism, so that the striking bolts move abruptly into the lower region of the tube interior and thus shatter the glass bottles, whose fragments then fall into the bottle bank. <IMAGE>

Title: Method for designing a healthy operating place and workplace for hairdressers
Inventor: HOELTER HEINZ DIPL ING
IPC: B03C3/017
Filed: 1986-11-13
Abstract: It is known that, when the hair is being treated by the hairdresser, very fine tips of hairs and hair spray are a nuisance, if not a risk, to both the hairdresser and the customers. In order to eliminate these disadvantages, it is proposed according to the invention that an air spray (4) is blown onto the hairdresser (1) him/herself and the customer (2), in such a way that purified fresh air, preferably purified by a bactericidal chemisorption filter, is blown starting from the face over the hair in the direction of the shoulder so that completely healthy air flows in the area of the nose and mouth, and the area of the operating hands is likewise sprayed and tips of hairs and accessories, such as hair spray, are caused to flow off in the direction of the back and floor by the slight air pressure and are retained on the floor, no longer whirled up, by an electrostatic surface (5). The chemisorption filter is switched on and off automatically by the sensor (6) by means of a sensor control which is sensitive to pollutants. <IMAGE>

Title: Lifting pump, especially for pumping petroleum from a deep well
Inventor: KLAEBISCH SIEGFRIED
IPC: F04B53/12
Filed: 1986-12-02
Abstract: A lifting pump, especially for pumping petroleum from a deep well, is equipped with a pump cylinder with an upstroke valve installed in the well hole immediately above the level of the liquid, and a piston with an outlet opening which is guided in the cylinder in a sliding fashion and is suspended from rods moved from the surface. The face of the piston has a sealing seat. The surface of the cylinder facing the piston has a sealing element corresponding to the sealing seat. Since the piston falls into the cylinder if a rod breaks, the sealing seat on its face can come to bear against the sealing element when a rod breaks, thus sealing the pump against eruptive emergence of the oil.

Title: Pressure modulator for a hydraulic brake system with anti-lock protection
Inventor: KIRCHER DIETER
IPC: B60T8/42
Filed: 1987-05-22
Abstract: A pressure modulator for a hydraulic brake system with anti-lock protection consists essentially of a regulating element (2, 2') which is guided in a cylinder (1, 1') and by means of which the volume of a working chamber (3, 3') situated in the path of the pressure medium of a brake system can be varied. The pressure modulator has an electric drive motor (6, 6') which is connected via a controllable gear mechanism (9, 22) and a screw link actuator (10) to the regulating element (2, 2'). The gear mechanism has a single or double planetary gear set, the internal gears (15, 30, 32) of which can be braked by an arresting or brake system (11, 23). It is thereby possible to actuate the clutch between the drive motor (6, 6') and the screw link actuator (10) and - in the case of the double planetary gear set (24, 25) - to reverse the direction of rotation of the output shaft (28). <IMAGE>

Title: Rotor design for helicopters having intermeshing rotors on vertical, parallel axes (shafts)
Inventor: KRATOFIEL MATTHIAS DR
IPC: B64C27/08
Filed: 1987-09-14
Abstract: The proposed rotor design for intermeshing rotors having vertical parallel axes 1a and b and blades 3 and 4a and b arranged in a V-shape is operated via swash plates 2a and b which are fixed in a universally jointed manner. The V-shaped arrangement of the blades 3 and 4a and b prevents collisions of the intermeshing rotors on vertically parallel shafts 1a and b and makes the transmission required for this purpose structurally simple, with low manufacturing and maintenance costs. The swash plates 2a and b with their internal universally jointed fixing (see design features 10-14a and b) allow the thrust maxima to be shifted to those blades 3a and b which project outwards at the rear, those blades 4a and b which project inwards at the front always assuming an incidence angle close to 0@. In consequence, the economy, efficiency, operational safety, speed and range are increased not only in comparison with conventional intermeshing rotor concepts with full torque compensation and good controllability in all directions. <IMAGE>

Title: Correlation measurement of the flow velocity of a fluid in a tubular conduit by means of ultrasonic sensors
Inventor: MAGORI VALENTIN DIPL PHYS
IPC: G01F1/7082
Filed: 1987-09-29
Abstract: A method for the correlation measurement of the flow velocity of a fluid in a tubular conduit by means of ultrasonic sensors, at least two ultrasonic sensors being installed at a predefined mutual separation, preferably flush with the inner wall of the conduit, in a line extending parallel to its long axis and inside it in such a way, that the main emission direction of the sensors is perpendicular to the axis and thus to the direction of flow. Discontinuities occurring in the flowing liquid are detected by using the ultrasonic sensors as distance-selective ultrasonic distance sensors (S1, S2) in a narrowly bounded region at a distance (z) from the distance sensor (S1, S2) involved in such a way, that the maximum of the cross correlation coefficient of the local separation-dependent output signals is detected via the velocity of a "stream filament" at distance (z), for which purpose the ultrasonic distance sensors (S1, S2) are operated according to the pulse-echo method known per se and, in so doing, only such echoes of which the time separation  DELTA t corresponds, at the given ultrasonic velocity (c), to the local separation (z) between the ultrasonic distance sensor (S1, S2) and the stream filament to be measured are evaluated. <IMAGE>
