Title: Treatment of ski pistes, downhill tracks and snow surfaces with mineral, vegetable or chemical substances
Inventor: BROCKMANN KARL
IPC: E01H4/02
Filed: 1984-05-12
Abstract: The treatment of snow pistes invented by me, Karl Brockmann, Architect, of 5788 Winterberg 2, for which a patent has been applied for, pursues the objective of wholly or partially eliminating the dazzle effect acting on the skier. In mist or diffuse light, the winter sportsman, especially if visually handicapped, is subjected to such a powerful dazzling effect that the course of the ski piste or the irregularities of the terrain can no longer be identified. This inevitably results in accidents and collisions. By artificially scattering or spraying suitable substances on the accessible snow surfaces, the dazzle effect would be wholly or partially eliminated. The winter sportsman is better able to identify the course and structure of the piste. Ski pistes and downhill stretches become safer, and accidents are largely avoided.

Patent DE-3423221-A1 (DE)
Title: Optical star coupler having a large number of inputs and outputs
Inventor: SANITER JUERGEN DIPL ING
IPC: H04Q3/52
Filed: 1984-06-21
Abstract: The use of monomodal systems is imminent for optical communications. The distribution and exchange of information signals in the optical region can be carried out with the aid of a passive device, a so-called star coupler, by means of which it is possible to split channels from all incoming lines uniformly between all outgoing lines. The power division in the passive optical star coupler causes the main component of the attenuation between the large number of transmitters and receivers that are connected, and is thus decisive for the number of subscriber stations that can be connected. In embodiments of the invention, the attenuation based on the power division depends linearly on the maximum number of inputs or outputs. This is achieved by cascading coupler elements, e.g. 3 dB couplers, the coupler elements being connected to one another from one cascade stage to the other in such a way that it is not until downstream of the last cascade stage that each outgoing line has the same composition of the components of all the incoming signals. By way of example, including internal losses and attenuation on splices, in such a star coupler approx. 42 dB occur in Type 512.512, and approx. 14 dB in Type 8.8. <IMAGE>

Title: Lifting platform with electronic synchronism safety feature
Inventor: FELIX HARRY DIPL ING
IPC: B66F7/20
Filed: 1984-09-08
Abstract: A synchronism safety feature provided for lifting platforms, in particular for those with which motor vehicles are lifted in workshops, provides for a potentiometer with a downstream electronic controller to be allocated to each lifting column. The control valve arranged in the hydraulic circuit between pumps and lifting columns and having a connection to the hydraulic tank is operated via the electronic controller. Restrictors are arranged upstream of the control valve in order to additionally prevent shocks in the system when control is effected. Serving as potentiometer is a 10-turn potentiometer which is influenced via a rotary spindle and on which a roller with a scroll spring sits on the one hand and a gear meshing with the gear allocated to the potentiometer sits on the other hand. Whereas the gears are arranged outside the pressure space and sealed off from it, the roller and the scroll spring as well as the appropriately ball-bearing-mounted part of the rotary spindle are accommodated in a pressure-tight bearing housing. <IMAGE>

Title: Oscillation damping system for travelling crabs
Inventor: KURZ HERBERT DIPL-ING
IPC: B66C13/06
Filed: 1984-11-02
Abstract: Load-oscillation damping systems are provided in particular in unit-load cranes such as container cranes with lifting-rope gear. Inclined ropes diverging at the top, which are fastened, for example, as special oscillation damping ropes to separately movable auxiliary crabs, require considerable equipment and operational input. This is avoided by an arrangement in with a travelling crab (1) with built-in lifting gear and V-shaped guidance of the lifting ropes (5, 6) is given carriages (11, 12) which run on tracks (17, 18) arranged on the travelling crab (1) and can be moved in the running direction of the crab. Fastened to the carriages (11, 12) are the lifting ropes (5, 6), which run off perpendicularly downwards from the lifting-rope drums (4) on the travelling crab (1), are deflected at the load-suspension means (10a) and are guided upwards in a V-shape. The carriages (11, 12) always enable the most favourable rope spread to be set in a very simple manner. <IMAGE>
