Title: Power-driven chisel or drill hammer
Inventor: WANNER KARL DR ING
IPC: B25D11/00
Filed: 1988-02-10
Abstract: To aerate and deaerate the piston space (8) during the idling of a chisel or drill hammer, the piston (5) has a lateral air passage (10) and the hammer tube (14) has an air passage (18). During the transition to the idling, the hammer tube (14) is displaced axially towards the tool holder (3) and simultaneously rotated, so that the air passages (10 and 18) coincide. The rotation of the hammer tube (14) is effected by a bolt (21) which is fixed therein and is guided in a groove (22) in the housing (1), running obliquely with respect to the axis of the percussion mechanism. By the rotation of the hammer tube (14), considerable shortening of the idling travel is achieved, with the result that the hammer is much more user-friendly. In the idling position, the percussion member (11) is held in a manner free from wear by an air spring in the space (33). <IMAGE>

Title: Process for producing solar silicon
Inventor: AULICH HUBERT DR
IPC: H01L31/18
Filed: 1988-02-10
Abstract: A process is proposed in which a silicon raw material still containing boron and oxygen after a first purification process is converted into a solar silicon by at least partial compensation of the boron content by addition of phosphorus-containing materials and a subsequent crystallisation or recrystallisation process. By means of the compensation, a greater diffusion length of the minority charge carriers is achieved in the solar silicon. As a result of this, solar cells produced from this material achieve higher performance. As raw material, even silicon oxide materials containing relatively high amounts of boron can be used. <IMAGE>

Title: Method and apparatus for trimming the edges of a textile shaped part
Inventor: EBINGER HERBERT DIPL ING
IPC: B26D3/10
Filed: 1988-02-13
Abstract: A method for trimming the edges of a textile shaped part, which is clamped in a holding apparatus, consists, instead of using a stamping knife acting against a base, in using a beating knife which is moved, at high speed, onto the dividing line to be produced and guided past the latter. By this means, the associated apparatus can be constructed in a substantially simpler and more cost-effective manner.
Patent DE-3809852-A1 (DE)
Inventor: CLUESSERATH LUDWIG DIPL ING
IPC: B67C7/00
Filed: 1988-03-24
Abstract: In a method and a device for filling containers, for example bottles, aseptically with liquid products using counterpressure, the particular container is subjected, in a sterilisation phase preceding filling, to the action of a pressurised hot, gaseous or vaporous sterilising medium on its inner surfaces, on its container mouth and on its outer surface adjoining the container mouth. In this process, the particular container is arranged completely in one chamber both during the sterilisation phase and during the filling phase in such a way that the container interior is in communication with the interior of this chamber via the container mouth. The sterilising medium is introduced into the container via a filling tube which serves for subsequent filling and is at a distance from the container mouth. The chamber is closed to the environment at least during part of the sterilising phase, but also during the subsequent filling phase, so that at least during this part of the sterilisation phase a sterilisation-medium pressure above atmospheric pressure is established in the chamber and during the filling phase the product is delivered to the particular container against a counterpressure prevailing in the interior of the chamber.

Title: Rotating armature electromagnet
Inventor: ISLIKER PETER
IPC: H01F7/14
Filed: 1988-06-28
Abstract: When a coil (14) is energised, a rotor segment (18) which is mounted such that it can rotate rotates in the anticlockwise direction into an operating position (18'). The restoring force when the coil (14) is switched off is applied by means of a tension spring (32). A second tension spring (28) is used for smooth limiting of the rotation angle. The U-shaped stator part (10) has a first limb (12) and a second limb (16) whose extension (36) is used for mounting and as a magnetic return path for the rotor segment (18). The iron parts of the stator part (10) and of the rotor segment (18) preferably consist of spheroidal graphite iron. The coil (14) is supplied with direct current. Such a rotating armature electromagnet with a single coil (14) is simple and robust in construction.

Title: Method and device for the examination of the surface condition in terrain which is difficult to access or inaccessible
Inventor: HOOGEN NORBERT DR ING
IPC: G01N3/40
Filed: 1988-10-13
Abstract: The invention relates to a method and a device for the examination of the surface condition in terrain which is difficult to access or inaccessible, a probe (10) being moved from a predetermined position in the direction of the surface to be examined and the measurement signals from the probe being evaluated for the determination of the surface condition. In order to obtain reliable measured values for the determination of the surface condition, especially for the bottoms of bodies of water, the probe is fired off or lowered in the direction of the surface, and its fall or locomotion acceleration and - as a measure of the surface condition - its braking (negative acceleration) when it encounters the surface are measured. For this purpose, a device is proposed which, as a portable device, has a probe (10) releasable in a mounting (11), the probe being able to be accelerated by means of an accelerator and having acceleration pick-ups for the determination of the penetration depth, the braking and the transverse forces (Fig. 1). <IMAGE>

Title: Method and device for automatic measurement and indication of the hit coordinates of supersonic projectiles on flying targets
Inventor: WERNICKE JOACHIM DR ING
IPC: F41J5/06
Filed: 1988-12-23
Abstract: The invention is based on a method for automatic measurement and indication of the hit coordinates of supersonic projectiles, fired from a tube weapon, in a predetermined hit plane on a flying target body by means of electroacoustic transducers and a computation device which uses the signals from the electroacoustic transducers to determine the hit coordinates of the projectiles on the hit surface, which method is intended to be improved together with a device used to carry it out such that the coordinates of the hit points of the projectiles can be determined. This is acheived according to the invention in that the measurement and indication of the hit coordinates are carried out by video-acoustic means using a video camera which is arranged on or in the vicinity of the weapon barrel and is slaved to the target movement such that the target always remains approximately in the image centre, as well as by means of an electronic evaluation device which determines and indicates the hit coordinates of the projectiles from the signals emitted by the electroacoustic transducer or transducers and the images of flying projectiles and of the target body detected by the video camera, and from predetermined state-descriptive data.
