Title: Throwing game
Inventor: CALE PETER
IPC: F41J3/00
Filed: 1989-01-04
Abstract: A throwing game with a target area and darts is proposed, in which longish naps are arranged on the target area for receiving the dart, and the darts have a rounded, blunt attachment at their front end. The risk of injury to players and spectators is thus considerably reduced, without thereby detracting from the feasibility of the throwing game.

Title: Slip-on fittings for plastic-insulated medium-voltage cables having integrated optical fibres (optical waveguides, light guides)
Inventor: AMERPOHL UWE DIPL ING
IPC: H02G15/188
Filed: 1989-02-20
Abstract: The known slip-on fittings (end connectors and sleeves) for plastic-insulated medium-voltage cables are intended to be developed so that they can be used for such cables having integrated optical fibres (medium-voltage optical-fibre cables), especially for single-strand XLPE cables having optical fibres integrated with the screening. The solution essentially consists in that the small protective tube (8) with the optical fibre is turned around an auxiliary winding (7) arranged in front of the field-control body (6) on the screening (4), and the optical fibre is connected by means of a splice (9) to an optical-fibre cable (10) or the optical fibre of the second medium-voltage optical-fibre cable, respectively. The excess length of the small optical fibre tube is wound around the auxiliary winding (7) or a compensating winding (12) and the sleeve tube (14). In the case of medium-voltage optical-fibre cables having a plurality of optical fibres, a flexible box-shaped housing is arranged instead of the tubular splice housing (9). These slip-on fittings are for medium-voltage cables having integrated optical fibres. <IMAGE>

Patent DE-3908917-A1 (DE)
Title: Marking carrier for electrical conductors
Inventor: WILMES MANFRED
IPC: H01B7/36
Filed: 1989-03-18
Abstract: In the case of this marking carrier for fitting onto already connected electrical conductors, the carrier body has a U-shaped clamping bracket (1) on whose free U-ends closing limbs (3) are articulated, which can move in a pivoting manner and are extended beyond the articulation zone by lever arms (5) which project into the longitudinal path of the conductor to be held. The closing limbs (3) are fitted on their free ends with locking hooks (7 and 8) which can form a positively locking connection with one another. If this marking carrier is connected onto the conductor, the conductor meets the lever arms (5). This leads to the closing limbs (3) pivoting, which move underneath the conductor in their closed position in which the locking hooks (7, 8) are engaged. The locking of the marking carrier on the underneath of the conductor is thus carried out automatically during the installation process. <IMAGE>

IPC: B28B3/26
Filed: 1989-05-13
Abstract: In the case of known drawing devices, the internals for influencing the extrudate are rigid or cannot be adjusted during operation of the press.
