Title: Double-sided tennis racket stringing
Inventor: KOPF HELMUT PROF DR
IPC: A63B51/00
Filed: 1983-07-27
Abstract: The longitudinal and transverse strings of double-sided tennis racket stringing are arranged in different designs in such a way as to allow individual methods of play, such as are customary today, with tennis rackets of this type, thereby greatly reducing the peaks of force occurring during impact in relation to single-sided strung rackets. The problem of the design of a stringing which is gentle on the arm has increased greatly in importance in recent times because today rackets with a very rigid frame are built on the basis of newly developed combinations of synthetic material. Although these rackets considerably improve the playing characteristics, they have the disadvantage that they have to be provided with a hard stringing which causes a great load on the arm. In rackets with such hard stringing, it is achieved according to the invention, by appropriate arrangement of the double-sided stringing in the region around the centre point of the stringing, that the playing characteristics of a single-sided strung racket are maintained, and better damping is effected than in the single-sided strung rackets by an appropriately different type of arrangement of the double-sided stringing in the most hazardous region at the four outer zones of the racket. For players who do not necessarily prefer the stringing surface at the centre of the racket to be as rigid as possible, the stringing takes place only in one arrangement. ...

Title: Synthetic production of rainbow holograms
Inventor: LESEBERG DETLEF
IPC: G03H1/08
Filed: 1983-12-05
Abstract: The synthetic production of rainbow holograms is performed by optical scanning of the brightness values of objects to be represented and converting them into electrical signals from which Fourier transform is formed line by line, for which it is also necessary to use digital computers. It is possible to process images of objects which are not physically present. The output signal produced can be transmitted and disseminated as information and stored on digital carrier media. It is fed, for the purpose of preparing the hologram, to an output device, where it controls the brightness of a light beam which is transmitted into a photosensitive carrier and focused by an astigmatic lens of suitable focal lengths in a vertically aligned focal line. A mask made from alternately transparent and non-transparent strips which are aligned parallel to the horizontal is positioned in front of the photosensitive carrier. During the writing of a row, a feed device moves horizontally at constant speed, and is thereafter reset and moves on vertically by the length of the focal line. It is possible to operate above the flicker frequency of the eye with a rapidly regenerating photosensitive carrier.

Filed: 1983-12-10
Abstract: The appliance serves for breaking up ground used for planting with a probe by which compressed air can be introduced violently into the ground via a quick-closing valve and substrate can be introduced into the ground via an injection valve. The quick-closing valve is arranged in the upper region and the injection valve in the lower region of an intermediate container for the substrate. The quick-closing valve is followed by an injector tube having a compressed-air outlet. With the quick-closing valve opened, the injector tube can be lifted off from an injection-valve seat of the intermediate container in order to open the injection valve. The quick-closing valve is coupled, for opening and closing, to the piston of a pneumatic cylinder and the injector tube is coupled via a lifting rod to the lifting piston of a compressed-air cylinder. Moreover, the injector tube is connected via an air line to a dynamic-pressure chamber colimited by the lifting piston and belonging to the compressed-air cylinder, in such a way that only after a substantial pressure drop of the compressed air breaking up the ground in the probe and in the injector tube can the latter be lifted off from the injection-valve seat as the result of an axial displacement of the lifting piston for the time-delayed opening of the injection valve.

Title: Double solenoid valve
Inventor: PAPE REINHOLD ING GRAD
IPC: A01J5/14
Filed: 1984-01-18
Abstract: The invention relates to a double solenoid valve, especially for the automatic milking of cows, two teats of the udder being alternately selected and placed under vacuum at any time. Since the system operates with a cycle overlap in order to obtain a better milking output, the vacuum can briefly break down when changing over. In order to prevent this a non-return valve is assigned to each valve seat of the double solenoid valve, which non-return valves with a flow passing through them open the full flow cross section but in the event of even slight differences in pressure close, thereby preventing breakdown of the vacuum.

IPC: H01H85/30
Filed: 1984-08-02
Abstract: The electrical protective device contains a fusible conductor wound on a former and arranged around a device indicating operation of the protective device, which has a moving bolt which is used for tensioning a spring device with a predetermined tensioning force via a tensioning wire, which is connected to the bolt and which breaks under the tensioning force on operation of the protective device. It is intended that this protective device should detect an overload of the fusible conductor below a disconnection current leading to its melting. To this end, it is provided according to the invention that the spring device (10) contains a spring element (12), which consists of an alloy with a temperature-dependent shape-changing characteristic such that, if a predetermined critical temperature is exceeded, the spring element (12) expands to such an extent that the tensioning wire (16) breaks on the basis of a corresponding heating power of the fusible conductor (4) when it is overloaded. As an alternative, according to the invention, a spring element of such an alloy can also be arranged in front of the bolt such that in the case of heating power from the fusible conductor in the case of an overload, the spring element deforms with an effective component in the direction of operation of the bolt. <IMAGE>
