Patent DE-4310639-A1 (DE)
Title: Device for the lateral guidance of a roller-blind shutter
Inventor: FAUSEL HEINZ
IPC: E06B9/58
Filed: 1993-03-31
Abstract: A guide rail (14) for a roller-blind shutter (18) is fastened on the outer side (13) of a window frame. In order to cover the plug-in openings (28) for the fastening screws (27), use is made of a front-attachment profile (31) which extends over the entire length and width of the front surface (21) and, engaging around the guide rail (14) by means of side legs (33, 34), is clipped firmly thereon. The front-attachment profile (31) can be readily coated once it has been removed, and it renders unauthorised demounting of the guide rail more difficult since its continuous surface does not give away the method of fastening. Consequently, the roller blind can be better used as a safeguard against break-in. <IMAGE>

Title: Ball-game set-up
IPC: G01B7/004
Filed: 1993-09-13
Abstract: In ball-game set-ups, substantially consisting of a playing surface and a ball, it has in the past sometimes been difficult to identify faults in play arising from the played ball landing in the transitional zone between the playing surface and the adjoining non-playing surface. The object of the invention, therefore, is to develop a ball-game set-up which permits certain, automatic identification of faults in play. To this end, provision is made for the ball, the playing surface, the adjoining non-playing regions and, if appropriate, a net dividing the playing surface to be provided with an electrically conducting layer, the playing surface A, the non-playing surfaces C and the net (13) being connected via contact lines to a computer provided with at least one signal emitter (15). Such a ball-game set-up can be used, for example, to monitor a game of tennis, the tennis court requiring appropriate design. <IMAGE>

Title: Windscreen-wiper mechanism giving reduced smearing of glass - has flexible transmission of reciprocating motion to smooth blade travel when subjected to varying friction e.g at reversals.
Inventor: IDE MORISHIGE
IPC: B60S1/24
Filed: 1993-10-29
Abstract: The windscreen-wiper mechanism has a uni-directional electric motor (not shown) driving a shaft (1) and crank (2) to which are connected the in-line links (3,4) connected at their mid-points by the air dashpot couplings (8) which provide flexibility. As the crank (2) rotates the ends of the links(4) transmit a reciprocating motion to the arms (5) resulting in a corresponding movement of the wiper-arms (6) and their blades (7). The couplings (8) contain a pneumatic piston and the elasticity of the system is varied via an electromagnetic by pass valve (9) which can also be used to adjust the sweep of the wipers (6,7) by the addition of the limit switches (10). ADVANTAGE - Reduces smearing/streaking caused by varying frictional contact of blades particularly at each reversal of motion. Smooths blade travel at all wiper speeds and prevents noise at reversals. Simplicity of mechanism reduces weight and cost.

Title: Device for coating the wall of holes in electrical printed circuit boards or multilayer printed circuit boards
Inventor: HAAS RAINER DIPL ING
IPC: H05K3/00
Filed: 1993-11-05
Abstract: In a device for coating the wall of holes in electrical printed circuit boards or multilayer printed circuit boards (3), the objects which are to be treated are moved forwards by a transportation system (6), horizontally aligned underneath the level (13) of a treatment liquid. Located underneath the movement path of the printed circuit boards or multilayer printed circuit board (3) is a flow guide box (16) which is divided by partition walls (20, 21) into a plurality of chambers (17, 18, 19). Seen in the movement direction of the printed circuit boards or multilayer printed circuit board (3), the chambers (17, 18, 19) are alternately connected to the pressure side and the suction side of a pump which conveys the treatment liquid. The top of the chambers (17, 18, 19) is formed by a perforated plate (24) which has a large number of apertures (25) which are distributed over the entire surface of the perforated plate (24). In this way, the printed circuit boards (3) alternately have a laminar flow applied to them over a large area from below and are sucked into a laminar flow over a large area from below essentially throughout the entire time during which they are passing through the treatment liquid. As a result of the long action time achieved in this way for the flows whose direction alternates, and as a result of the relatively low flow speeds which can be achieved at the same time in this case, the through-holes which are present in the printed circuit boards or multilayer printed circuit boards (3) are on the one hand completely and reliably ...
