Title: Arrangement for multi-stage restriction in control valves
Inventor: BAUER PETER ING
IPC: F16K47/04
Filed: 1982-06-28
Abstract: The invention relates to an arrangement for multi-stage restriction in control valves with orifice restriction bodies which are arranged in a housing, and of which at least one is assigned a control edge, a spindle being provided to produce a relative motion between these orifice restriction bodies and the associated control edge. For the purpose of achieving fully effective restriction over the entire stroke range with a low outlay it being particularly desirable to use conventional valve housings and as far as possible to avoid physical unsteadiness in the flow through the orifice restriction bodies, the invention provides for the provision of a plurality of concentrically arranged orifice restriction bodies with mutually independent flow area characteristics and associated control edges, the relative motion between all the orifice restriction bodies and the associated control edges being provided, and at least some of the orifice restriction bodies have different diameters, the components bearing the control edges being arranged between these orifice restriction bodies, with the result that, in particular, a radial flow is obtained between the individual orifice restriction bodies. <IMAGE>

Title: Door hinge
Inventor: LANGER HEINZ
IPC: A47G25/06
Filed: 1982-08-06
Abstract: In toilet rooms or the like, it is often to be observed that the hangers arranged on the door leaf of the corresponding door are either wilfully removed or else are only loosely fastened, so that it is no longer possible to hang the clothing, such as coats, etc. These disadvantages are to be avoided by means of the invention, in which the upper door hinge of the respective door is equipped with the hanger. This affords a plurality of possibilities. On the one hand, the hanger can be connected directly to the hinge upper part or the hinge lower part, and it is also possible to arrange the hanger between said two parts on the pin of the hinge lower part. A wilful removal of this hanger is virtually impossible, and therefore the user of a toilet or the like has the possibility in a reliable way of hanging up his clothing.

Title: An automatic release of the safety-belt buckle
Inventor: HANSEN ADOLF PAUL ERNST
IPC: B60R22/32
Filed: 1982-11-20
Abstract: On a non-isosceles mounting angle 3 in Figures 1, 2 and 3, the conventional belt buckle is fastened to the long leg. The slide angle 11 moves through long holes 12 on the short leg of said mounting angle, and the shift slide 18 together with the shift finger 19 moves on said slide angle 11. The slide angle 11 is equipped with a tension-spring column 14 and is connected to the spring-column angle 16 by means of the tension spring 15. The shift slide 18 together with the shift finger 19 has, in Figures 2, 3 and 7, a compression spring 21 which allows a push position of these. When an advance of the slide angle 11 of a particular amount takes place, the two parts are then connected by means of the narrowing 26 of the telescope 24. When the advance is equal to zero, the tension spring 15 pulls the connected parts into the position of rest. The switch finger 19 presses the conventional plunger of the belt buckle back for the purpose of release.

Title: Dispenser device for toilet flushing box
Inventor: PHILIPP FRITZ VON DIPL ING
IPC: E03D9/03
Filed: 1983-02-09
Abstract: The device has a perforated dispenser/container which is submerged in the flushing water in the toilet flushing box. The dispenser/container 4, 4a, 4b is not, as previously, arranged on the wall of the flushing box but on the valve pipe 8 or actuating lever 6. An additional weight 10, 10a, 10b can be slipped onto the dispenser/container 4, 4a, 4b. In this manner, the valve pipe 8 is loaded in such a manner that it is pressed back onto its seat 9 immediately after release of the actuating knob or actuating lever 6a. Flushing water can therefore flow out of the flushing box only for as long as the actuating knob or lever 6a is pressed down. Adjustment of the flushing water is thus provided - by means of the dispenser/container which is in any case required. <IMAGE>

Title: Screwdriver
Inventor: WEBER KARL HEINZ
IPC: B25B23/145
Filed: 1984-01-25
Abstract: A motor-operated screwdriver is described which can be controlled as a function of the emerging torque, works reliably and safely and is therefore especially suitable for automatic production plants. The screwdriver has a torque sensor with two switch points for the mechanical measurement of the torque, a measurement transducer for measuring the torque actually occurring and possibly the rotary angle, and an indicating and comparison unit which undertakes the analysis of the delivered signals. In an especially preferred exemplary embodiment, the torque sensor consists of a worm and a worm outer casing mounted coaxially to the worm and moving in the radial direction relative to the worm under the loading of the screwdriving resistance. The worm outer casing has a control edge which causes the torque sensor to transmit a signal when one of the two switch points is reached. Torque and rotary angle are measured simultaneously. The signals are fed to the indicating and comparison unit, which is conveniently connected in such a way that the screwed connection is codified as "good" only when both the torque sensor and the measurement transducer signal the correct sequence of the screwdriving operation. In this way, the torque sensor and the measurement transducer check one another.

Patent DE-3407454-A1 (DE)
Title: Combination of solar collectors and heat pump
Inventor: DIETRICH HANS-JUERGEN
IPC: F24D18/00
Filed: 1984-02-29
Abstract: In the heating installation, the solar radiation is not used, as normal up to now, only to heat the service water or heating water, but to drive a turbine which drives a compressor on the secondary side. The compressor can once again obtain more useful heat from the available primary energy (such as, e.g., air, earth etc.) by means of a cooling circuit. The efficiency of the installation increases as a result. If the solar energy is too low, a drive motor operates the compressor and the installation is thus always ready for use. Owing to the special design, the entire heating energy can be fed directly via a priority circuit into the service water preparation system if the service water temperature is too low. As a result, a limited amount of hot water is always directly available within a relatively short time. Moreover, the receiving capacity (e.g. in the case of electric compressors) can be just below the free limit of the energy supply company, so that a heating installation is available which is free of charge, can be used at any time and is suitable, in particular, for one-family and two-family houses.

This results in ... Original abstract incomplete.
Patent DE-3424564-A1 (DE)
Title: Ski-roller training apparatus for cross-country skiing with running wheels arranged on axles at the front and rear and an anti-return lock by means of which the return running of at least one running wheel can be prevented
Inventor: HEIDELBERGER RALF KLAUS
IPC: A63C5/06
Filed: 1984-07-04
Abstract: Ski-rollers are equipped with anti-return locks which absorb all backward-directed forces and hence do not permit rolling back in the push-off phase during the diagonal step, such as arises during cross-country skiing when the [lacuna] by the nature of the snow and coefficient of friction of the running surface of the skis is exceeded. The movement processes and force ratios encountered in cross-country skiing can be simulated thereby only to a limited extent. Since the maximum push-off force, exceeding which causes the ski-roller to roll back, can be adjusted within a range which corresponds to the conditions during cross-country skiing, the anti-return lock arranged on one of the axles of the running wheels is connected with an adjustable friction clutch in such a manner that the effect of the anti-return lock can be partially cancelled. The outer ring of the anti-return lock is rotatably mounted in the longitudinal support of the ski-roller and its rotatability can be influenced by a braking element whose contact pressure on the outer ring can be adjusted. The anti-return lock represents the only bearing for one of the axles of the running wheels.
