Patent DE-3404559-A1 (DE)
Title: Paratron radiator
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H05H7/00
Filed: 1984-02-09
Abstract: A high-vacuum paratron radiator for infrared or optical or X-ray emissions is described, which allows beams of any desired cross-section to be emitted. Using a tubular, cylindrical anode, it converts the cathode rays into X-rays such that the latter occur in coincidence with the cathode rays causing them, it being possible for the useful effect to become very large. The cathode rays strike against the anode hole with only a very small residual energy, and the anode heating and the anode wear are in consequence very small. Wherever the cathode ray starts to pivot in a quarter circle at its end onto the anode hole, virtually all the kinetic electron energy is emitted out of the tube in accordance with the principle of synchrotron or betatron radiation, namely tangentially with respect to the quarter-circle arc. In conjunction with a betatron which preamplifies the electrons, is simple and is relatively small, the paratron radiator allows quantum energies up to 50 MeV of the X-ray emission, and X-ray pulses up to gigajoules at a pulse frequency of 50 Hertz to be achieved on a standard AC network. Coherent X-ray beams can also be generated for industrial and medical purposes, and in particular also for military applications.

Patent DE-3545943-A1 (DE)
Title: Aerodynamic lift and propulsion system
Inventor: BOERNER HEINZ
IPC: B64C11/00
Filed: 1985-12-23
Abstract: This completely novel lift and propulsion system is distinguished by a large airflow rate which is deflected organically on the large bell surfaces in order to achieve powerful lifting forces. The airflow rate in kg/s determines the reaction force, that is to say the lift. It is also necessary to take note of its physically small construction, robustness and structural simplicity (cheapness). In addition, the generally hazardous and severely intrinsically hazardous long rotor blades of conventional helicopters are obviated and even a collision in the air need no longer lead to the machines involved crashing if the relatively small lift units remain undamaged. They can additionally be protected by being embedded. The system opens up the possibility of individual air transportation, of the air car, which can take off and land in a very small space. It makes possible a "rucksack lifting apparatus", for example for installers, fire service personnel, and mountain rescue personnel etc. Because of its compactness, it can be used for operational purposes which cannot yet be predicted.

Title: Breaking-up (tearing-up) beam sections
Inventor: SCHOELKOPF WALTER
IPC: E01C23/12
Filed: 1986-04-02
Abstract: The invention relates to a breaking-up beam section for increasing the breaking-up width of a breaking-up beam (2) independently on both sides, so as to form a variable breaking-up device. These implements are used in repair, renewal and recycling work and in the restoration of a bituminous layer as it is generally replastified by supplying heat, then loosened up, laid to the correct profile again and pre-compacted. In a second operation, this layer is covered by new bituminous mixture and the two layers are jointly compacted. The object is to supplement a breaking-up device by breaking-up beam sections to form a variable breaking-up device which enables exact widening, added in steps, of the subgrade (formation) to be worked. According to the solution, provision is made for the breaking-up beam (2) of the basic implement (1) to be assigned, on both sides, a hollow box profile (3) which in each case projects to the same extent into the space between the beam supports (2.2). A sword-shaped supporting profile (3.3), to which the breaking-up elements are fastened in a manner passing through and directed towards the subgrade, is in each case arranged in the hollow box profile (3). The breaking-up width is established by in each case one pressure cylinder (6) fastened to each hollow box profile. <IMAGE>

Patent DE-3640569-A1 (DE)
Title: Sieve cleaner
Inventor: FILIP MARTIN
IPC: B07B1/54
Filed: 1986-11-27
Abstract: A known sieve cleaner consists of an approximately triangular disc-shaped basic body, in the edge region of which upwardly projecting wiper elements - bristles or plastic fingers - are arranged, which have the same length and same diameter and stand parallel to one another. This arrangement and design of the wiper elements is to be improved in order to intensify the cleaning effect. The known sieve cleaner is moved further solely by the working movement of the sieve machine, as a result of which it can only poorly release itself from a blockage. The new sieve cleaner has wiper elements (2, 3) whose length and diameter are different in order to improve the cleaning effect. Furthermore, means are provided for shifting the centre of gravity, so that, by virtue of an additionally acting force moment, the sieve cleaner can better release itself from a blockage. For this purpose, in an exemplary embodiment, a previously centrally arranged foot-like attachment (17) is arranged eccentrically on the underside of the basic body (1). The sieve cleaner is inserted in sieve machines between the sieve and sieve plate. <IMAGE>

Patent DE-3704109-A1 (DE)
Title: Absolute-value measuring system
Inventor: THIEME UWE DIPL ING
IPC: H03M1/24
Filed: 1987-02-11
Abstract: The system is a further development of known measurement-value detectors involving sampling of the Gray code. It allows much higher resolution since the code carrier is coded and sampled on both sides.   This becomes possible since the light is fed in on the side and conducted in the code carrier in the manner of an optical waveguide. Additional code tracks for one parity bit for each data byte and for converting the Gray code into a binary BCD or other number increase the reliability of data transmission and decoding speed. In multi-stage absolute-value transmitters, the stepping-down occurs coaxially to the drive shaft by means of planetary step-down stages so that the identical coding system as for the angle detection can be used for counting the revolutions.

Title: Blank firing attachment for an automatic tube weapon (weapon with a barrel)
Inventor: KALTMANN HANS-JOACHIM
IPC: F41A21/26
Filed: 1987-05-05
Abstract: The invention relates to a blank firing attachment 1 for an automatic tube weapon and is connected to a muzzle 6 of a weapon barrel 7 in order to fire blank cartridges without any projectile. The blank firing attachment 1 is used to control the gas pressure behaviour of the propellant charge gases in order, in the case of tube weapons which are controlled by gas pressure, to simulate a functional sequence as well as the muzzle sound and weapon recoil in a similar manner to the processes when firing live ammunition. The particular advantage of the blank firing attachment 1 according to the invention is the capability to match a standardised blank firing attachment 1 to different weapon barrels and different blank cartridges, by adjusting a gas piston 4 in the housing 2. In the case of a further particularly advantageous exemplary embodiment of the invention, the blank firing attachment 1 is provided with a gas deflection ring 15 so that the recoil of the weapon barrel 7 can be increased by the propellant charge gases flowing out. Furthermore, adapters are provided which allow the combination of a standardised blank firing attachment 1 according to the invention with different muzzle diameters and rifling. <IMAGE>
