Title: Method and arrangement for independently operating a plurality of rail-bound vehicles, in particular model railways
Inventor: SCHWAIGER KLAUS
IPC: A63H19/24
Filed: 1986-04-21
Abstract: A method which permits a plurality of model railway trains of a model railway system to be controlled independently of one another is described. The installation of a control or decoder logic in the respective traction units to be addressed is dispensed with in this arrangement so that even the smallest known model railways can be used. Control is achieved in this arrangement in such a way that both the route and also movements of traction units as well as all control processes of points or signals are transmitted in a suitable form as data to a central processing unit. The propulsion voltages for the individual traction units are fed on a section basis to the route, when changing between sections, the corresponding propulsion voltages are carried over from section to section under the control of the central processing unit. The number of sets of railway wagons to be operated is restricted simply by the number of block sections provided.

Title: Apparatus for sealing traffic openings
Inventor: FREIMUTH FRIEDRICH
IPC: B65G69/00
Filed: 1986-09-09
Abstract: Sealing of traffic openings, i.e. the gap between vehicle and gate opening, is, for example, necessary in order to protect colleagues from inclement weather. The traffic openings must have a seal, even when vehicles are passing through. In order to seal two areas, a medium is guided via channelling devices in the region of the gap. The medium is extracted from the side to which it is also supplied back again. If band-type or member-type objects are moved through the opening or if the objects remain in the opening, the gap is effectively covered.   The embodiment is characterised by low power consumption and a low noise level. Furthermore, the manufacturing outlay has been reduced. An exemplary embodiment is shown in the following diagram. <IMAGE>

Patent DE-3711021-A1 (DE)
Title: Composite fabric for the sheet-forming part of a papermachine
Inventor: VOEHRINGER FRITZ
IPC: D03D11/00
Filed: 1987-04-02
Abstract: The upper and lower fabrics are woven together with longitudinally-directed or transversely-directed binding threads. By means of the latter, the different transverse contractions of these fabrics can be controlled, but not the oscillating relative motions between the upper and lower fabrics, which motions are caused by continuous load changes during the passage through the roll system of the wet end in the direction of running and which destroy the binding threads by friction. The composite fabric should therefore be formed in such a way that it is particularly suitable for absorbing longitudinally- and transversely-directed displacement stresses, by almost cancelling the elongation of the longitudinally-directed binding thread parts by the shrinkage of the transversely-directed binding thread parts, so that a substantial reduction in the relative motions between the upper and lower fabrics is achieved. For this purpose, it is proposed that at least some of the binding points of at least a part of the binding threads in the upper fabric are arranged relative to each of the binding points in the lower fabric, following in the longitudinal direction of the binding threads, in such a way that the binding points following one another alternately in the lower and upper fabrics in the longitudinal direction of the binding thread are laterally offset relative to the perpendicular on the wire surface, the projection of at least part of the binding threads onto a plane parallel to the wire surface being a zig-zag line at least in part lengths.

Patent DE-3801904-A1 (DE)
Title: Screw mechanism
Inventor: STRACHE WILHELM
IPC: F16H25/20
Filed: 1988-01-23
Abstract: For control and regulation use is often made of actuators which require a purely linear actuating motion. This requirement is met, for example, by linear actuators which employ an electric motor; however, these are considerably more complex and expensive than rotary actuators employing an electric motor. The new screw mechanism is intended to make it possible to combine a linear actuating element with a rotary actuator while keeping down the overall height. The screw mechanism has a short housing (9) to be arranged between the rotary actuator (1) and the actuating element (5), a driving part (12) being mounted in an axially fixed but rotatable manner in this housing. A coupling spigot (13) projects into the rotary actuator (1) and is, at the same time, designed as a spindle nut. Supported in the latter is a spindle (18) with a section (20) of polygonal cross-section. This is guided in a polygonal housing opening (21) so that it can execute a stroke but is secure against rotation. The spindle (18) has connection means (22) for the operating shaft (8) of the actuating element (5). The screw mechanism is for use as an adaptor between rotary actuators and actuating elements to which a purely linear motion is to be imparted. <IMAGE>
