Patent DE-3818718-A1 (DE)
Title: Driving pulley and block for a driving pulley
Inventor: JACOBSSON KURT ARNE GUNNAR
IPC: F16H55/54
Filed: 1988-06-01
Abstract: The invention relates to a driving pulley with a variable working diameter which comprises radially adjustable blocks that define a polygon similar to a circle with their backs. A lining composed of an elastic and frictional material with a positive-locking action in the circumferential direction is attached to the back of each block so as to be releasable transversely to the circumferential direction, allowing the shaped lining component to be replaced easily when it has worn. The block forms a unit with the shaped lining component and the said shaped lining component can be removed either in the axial direction after the driving pulley has been disassembled or in an approximately radial direction without disassembly of the driving pulley to allow replacement. The shaped lining component is either a homogeneous rubber or plastic component or consists of a hard supporting body with a lining layer bonded to it. <IMAGE>

Patent DE-3828100-A1 (DE)
Title: Method for coding information of one, two or more channels and/or frequency reduction of the alternating coding current or currents and transmission of the latter
Inventor: DIRR JOSEF DIPL ING
IPC: H04N7/24

Title: Device for screening, absorbing and generating radiation (earth radiation)
Inventor: MUEHLENBEIN RUDOLF
IPC: A61N1/16
Filed: 1988-11-05
Abstract: Underground flowing water veins generate a magnetic field which emits radiation (earth radiation). The measurable emergence of radiation from the ground is wedge-shaped or sector-shaped. The earth radiation influences biological systems, e.g. humans, animals and plants. The earth radiation can be screened off by a magnetic plate (10) which is mounted against the radiation direction and whose length depends on the width of the radiation field (12). The room is freed of radiation above and behind the magnetic plate. The magnetic plate (10) is made of sheet steel which is magnetised by an electric direct current magnet or a permanent bar magnet. <IMAGE>

Title: Safety hook for trapeze belts
Inventor: JUNG URS
IPC: B63H9/10
Filed: 1988-11-09
Abstract: The safety frame for trapeze hooks consists of a hook-in frame (2) with limbs (3) projecting horizontally from a fastening device, and of a hook tongue (4) adjacent thereto.

Title: Method for identifying anoprop targets in a pulse radar system
Inventor: MINKER MANFRED DIPL ING
IPC: G01S7/292
Filed: 1988-11-24
Abstract: In order to identify anoprop targets in pulse radar systems having block-by-block processing and an agile pulse repetition frequency it is proposed to provide the target returns with tags which indicate whether the target report originates from signals from only one pulse repetition frequency, and possibly which, or various pulse repetition frequencies. In the event of a track being formed from the target returns from successive antenna revolutions, an additional check is carried out to determine whether the target returns are based on target detections and different pulse repetition frequencies.
