Title: Vehicle running chain
Inventor: WILLER JOHANN WERNER
IPC: B62D55/24
Filed: 1981-03-30
Abstract: Piste vehicles which are equipped with track chains, are intended for taking care of and monitoring pistes and act as ski-track apparatuses have multiple profile rails which are designed like blades so that, as a consequence of line contact with the underlying surface, they cause a very high surface pressure. The running mechanisms have a considerable weight produced by the metal profiles and the bolted connections. The vehicles can only achieve low speeds. As a consequence of the aforementioned, they also destroy the underlying surface. The vehicles are not permitted to travel on roads. The invention provides running chains for vehicles of this type, which running chains are distinguished by a plurality of running bands which are arranged parallel to one another, are composed of elastically flexible material and are connected to one another by rod-shaped elements which are arranged transversely to the direction of movement. A vehicle equipped with running chains of this type can travel both on the road, with an authorisation in accordance with the regulations, and at high speeds, and can also develop the necessary traction on snow-covered ground with very steep gradients.

Patent DE-3131858-A1 (DE)
Title: Fluidising device for container linings
Inventor: STRESE GERHARD
IPC: B65D88/66
Filed: 1981-08-12
Abstract: On container linings for transporting bulk materials which are to be pressurised for emptying by compressed air whilst fluidising the bulk material, in practice an excessively high consumption of compressed air is usually applied. The excessively high consumption of compressed air is disadvantageous not only in terms of energy, but also in respect of the constructional expenditure of producing the compressed air. This is counteracted according to the invention, in that the air consumption is restricted to 0.4-0.6 m<3> per m<2> of the container bottom per minute. With such an air consumption, a sufficient degree of fluidising is still ensured in standard containers.

Title: Process for pressure-controlled H2/O2 recombination
Inventor: LEDJEFF KONSTANTIN DR DIPL-PHY
IPC: C01B5/00
Filed: 1981-10-30
Abstract: In the catalytic combustion of H2 and O2 in a recombination reactor, the gases are fed alternately to the reactor via inlet valves which are designed such that they always open at one internal pressure P1 of the reactor, but close at different internal pressure p2/H<2> or p2/O<2>, so that the admitted rates of H2 and O2 are in a ratio of 2:1. The initial filling of the reactor with one of the gases (for example H2) as a purging gas and the first feeding of the other gas (O2) at a rate exceeding the equivalence to the first gas have the consequence that, during the subsequent recombination, residue of the fed gas remains, which in turn is overcompensated by the next gas feed and is recombined with overstoichiometry of this gas. The constant repetition results in a continuous gas consumption which, in its course in time, oscillates between an overstoichiometry of O2 and an overstoichiometry of H2. <IMAGE>

Title: Pivoting-shackle lock, especially for bicycles
IPC: B62H5/14
Filed: 1982-02-02
Abstract: What is proposed is a pivoting-shackle lock (10), especially for bicycles, having a shackle holder (26) fastened to the bicycle frame (12), a pivoting shackle (32) equipped with a push-in extension (34), and a cylinder lock (29) for securing the push-in extension (34) in a receptacle (38) of the shackle holder (26). In this secured position (32'), the pivoting shackle (32) cannot be pivoted, since an outer polygon (42) of the push-in extension (34) engages into a corresponding inner polygon (44) of the shackle holder (26). On the contrary, in the released position (32''), the pivoting shackle (32) can be pivoted about the pivot axis (40). So that the pivoting shackle (32) cannot be lost, there is attached to the push-in extension (34) a stop disc (50) which, in the released position (32''), butts against a stop face (56) of the receptacle (38). <IMAGE>
