Patent DE-3412622-A1 (DE)
Title: Paratron emitter
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H05H7/00
Filed: 1984-04-04
Abstract: As an improvement to the paratron emitter of the main application, the semicircular arc is attached to the straight-line path instead of the quarter-circle arc, as the end of the accelerator path. The landing speed of the electrons on the anode is in consequence virtually zero, in the same way as the anode heating. Apart from the emission of photons at a Planck frequency of between 10<13> and 10<23> Hertz, paratron emitters for paragraviton and neutrino emission are also described which, however, are no longer pure electron types. A purely mechanical rotor or a hydraulic rotor for paragraviton emission is shown, and a proton circular accelerator combined with neutron injection is shown as a paragraviton emitter. Furthermore, a paraneutrino directional emitter which acts with nuclear neutron generation is described which is suitable for neutrino telephony using a brand which can be modulated. It is still open as to whether a receiver will ever be provided for this purpose.
Patent DE-3419112-A1 (DE)

IPC: A01D34/86
Filed: 1984-05-23
Abstract: The device comprises a yoke (22) which is attached to a supporting frame (11) on a vehicle and can be swivelled to a limited extent about the longitudinal axis (A) of the said frame. In addition, a supporting lever (23) is mounted in such a way that it can swivel with one end (23') concentrically to the swivel axis of the yoke and is suspended flexibly on the yoke (22). At the other end (23'') of the supporting lever (23), the tool implement (2) is held in such a way that it can swivel about an axis (B) running parallel to the longitudinal axis (A) of the supporting frame (11). This arrangement makes it possible to swivel the tool implement (2) about two axes (A) and (B), so that adaptation to the respective form of soil can be carried out easily. Furthermore, the weight of the tool implement (2) is balanced in every operating position, so it rests with only a small, adjustable force on the soil to be worked and can consequently be moved away over it at an adjustable distance. This avoids damaging the soil or the soil-working tools. <IMAGE>

Title: Printing with gaps
Inventor: MEYER MARTIN
IPC: B42D15/00
Filed: 1985-02-14
Abstract: The actual invention (and discovery) lies in the linguistic/literary area of the intellectual domain (understanding the meaning of sentences). The outward effect of the invention is to make the meaning of sentences obvious when literary texts are printed, to be precise by means of a special printing method. The printing method consists in leaving "printing holes" at certain points in a sentence, which make the meaning of the sentence easier to understand. The difficult problem of reading and understanding sentences and texts (for children and adults alike) is substantially solved as a result of this. The invention can be used in the printing of literary works of all kinds, as long as they are written in German; translations of foreign-language texts into German are also included.

Patent DE-3515560-A1 (DE)
Title: Heat engine for using environmental heat, in particular atmospheric heat
IPC: F02C1/10
Filed: 1985-04-30
Abstract: The invention relates to a heat engine for using inherently balanced environmental heat such as, e.g., normal atmospheric heat or heat from water. It is particularly suitable for relatively large stationary power plants (power stations). Such heat engines can be operated in a closed or open cycle. In the case of an open cycle (Fig. 1), atmospheric air is sucked in directly via a compressor, and the hot compressed air is fed to a binary alloy nozzle via which the air (likewise atmospheric) is sucked in. The mixed product obtained, which has the new pressure and the new temperature, is expanded by a turbine and fed back - expanded and cooled - into the atmosphere. As a thermodynamic calculation shows, the mechanical work obtained from the mixed product in the turbine is greater than the work required to provide the compressed air at the compressor. The difference between the two works (W3,4-W212, Fig.2) can be dissipated to the outside in a useful way; it is the mechanical thermal equivalent of the atmospheric heat (s4-s1, Fig.3) lost at the turbine output. In the closed cycle, the working material is a gas or vapour of high specific heat in conjunction with a relatively high basic pressure. The take-up of heat from the environment, e.g. from the atmosphere, the water or the earth, is absorbed by a heat exchanger, and released to the colder gas expanded by the turbine. The ...

Filed: 1985-05-15
Abstract: The objective of the apparatus is to prevent the misuse of data in accordance with the Federal German Data Protection Act where such data are stored or are to be stored on diskettes or floppy disks. For this purpose, there is arranged inside the disk drive an apparatus which has, inter alia, two punching dies and a photocell in such a way that the punched perforations made by the punching dies located above the magnetisably coated disk can be made in the direct vicinity of the circular centring and driving opening of the disk, and can be converted into electric pulses by a photocell in the same or a subsequent processing step. The punching out of codes or identifications can be performed in binary, alphanumeric, alphabetically compressed or alphabetically uncompressed form according to choice by means of a switch. In addition, the index perforation for sectoring the tracks themselves can be performed independently of the punching out of the codes or identifications. All characters to be punched are entered via the keyboard. A code memory which is connected to the punching mechanism and can be safeguarded against overwriting and erasure compares the diskette to be processed with the stored code or identification and allows processing or excludes it from processing. A major advantage of this apparatus is, inter alia, that the operating system used... not the functions of the apparatus ... Original abstract incomplete.
