Title: Sequence controller for a rotating platform or sliding platform for model railway systems
Inventor: JAUMANN ROLF DIPL-ING
IPC: A63H19/32
Filed: 1981-12-17
Abstract: A sequence controller for a rotating platform or sliding platform, driven by an electric motor, for model railway systems has a loop contact arrangement for positioning the platform at a preselectable rail connection, which loop contact arrangement is connected in the circuit of the motor, has a wiper attached to the platform and has a number of contact segments corresponding to the number of rail connections, which contact segments are connected individually to in each case one contact maker, allocated in equal priority to the rail connections. The individual contact makers can optionally be operated by a wiper of a selector switch such that the motor remains switched on for a continued movement of the platform, with the involvement of control electronics, until the rail connection which has been preselected by means of the wiper of the selector switch is reached. The control electronics are preferably constructed such that the platform in each case travels by the shortest route to the preselected rail connection.

Title: Process for producing cadmium sulphide selenide (CdSxSe1-x) mixed crystal layers
Inventor: MARSCHALL NORBERT DIPL PHYS DR
IPC: H01L21/363
Filed: 1982-04-23
Abstract: In a process for producing cadmium sulphide selenide (CdSxSe1-x) mixed crystal layers using cathode sputtering, the starting substance, cadmium selenide (CdSe) is cathode-sputtered in a gas mixture composed of an inert gas, such as argon, and a specified proportion (for example up to 5% by volume) of hydrogen sulphide, in particular and expediently in a flowing gas mixture with a regulated flow rate. The process makes it possible to establish, in a simple way, certain x values which may be altered continuously or abruptly even during the growth of the layer. The mixed crystal layers obtained are advantageously used as photoconductors in electrophotography or for a display drive. As an interlayer in multilayer systems, they are used to establish the work function of charge carriers.

IPC: E21D23/00
Filed: 1982-07-08
Abstract: The mechanised support assembly has a cover (1) which is connected to the base plate (3) by hydraulic props (2). Provided in the goaf-side part (5) of the base plate (3) is a hydraulic pushing cylinder (7) for the separate advance of the conveyor (8) and the support assembly. The piston rod (10) of the pushing cylinder (7) is fastened to one end of a ram (11), the other end of which is connected to the conveyor (8). A further hydraulic cylinder (13) is mounted in the coal-face-side part (4) of the base plate (3) in such a way that its piston rod (14) moves in the direction perpendicular to the advancing direction of the piston rod (10) of the hydraulic pushing cylinder (7) and interacts with the ram (11) via a sliding piece (15) which is frictionally connected to the base plate (3). The ram (11) is arranged on the floor and serves as a guide for the sliding piece (15) during the advance of the support assembly. The sliding piece (15) is pressed continuously against the ram by the piston rod (14) of the hydraulic cylinder (13), for which purpose the piston-rod space is constantly connected to the pressure source. During variation in the length of the hydraulic props (2), the coal-face-side part (4) of the base plate (3) can be lifted away from the floor while the cover (1) maintains constant contact with the roof. <IMAGE>

Title: Multihull hydrofoil boat
Inventor: BUSS WILLI
IPC: B63B1/24
Filed: 1983-04-19
Abstract: The subject matter of the invention is a multihull boat (catamaran or trimaran), to the keel plates of which several dynamic buoyancy elements (hydrofoils) are attached. The frame profile of the hulls is configured in such a way that, at increasing speed, the dynamic buoyancy forces of the hydrofoils can replace the static buoyancy forces of the hulls in linear reversal. An efficient operating behaviour is thereby obtained over the entire speed range.

Title: Process for treating the waste water produced in the production of wet phosphoric acid
Inventor: GOSCH HANS-WERNER DIPL ING
IPC: C01B25/225
Filed: 1983-04-20
Abstract: In this process, the gypsum slurry produced in the crude phosphate digestion is stored as a liquid and the waste water draining from the gypsum slurry dump is subjected to a two-stage neutralization. In this, the waste water is first brought to a pH of 2.5 to 4.5 by addition of calcium ions and is then brought to a pH of 9 to 13. After the slurry separation has been carried out, all or part of the neutralized waste water is returned as washing water to the phosphoric acid filtration stage. Excess waste water in this case can be disposed of by evaporation.

Filed: 1983-09-08
Abstract: In order to achieve an immediate or forced triggering, without preparation, of an acoustic alarm, in particular in the case of attack by a violent criminal, and at the same time to prevent the alarm from being immediately switched off by said criminal, a functional unit, consisting of signal sources driven by gas pressure, a gas-filled pressure container, an opening valve and a rip cord with a ring grip for opening the valve, is integrated in a bolted housing having sound-emitting openings. By virtue of its compact dimensions and low weight, said housing, which at the same time has a high sound output, can be conveniently carried along in a special shoulder bag, immediate or forced triggering being rendered possible by, e.g. connecting the rip cord to the wrist. A pneumatically controlled changeover switch can be used to actuate a plurality of signal sources to generate a characteristic signal.

Title: Lagging mat with clamping element
Inventor: QUANTE HEINRICH
IPC: E21D11/15
Filed: 1983-09-13
Abstract: In underground mining and tunnelling the intermediate spaces between channel sections curved in opposite directions are effectively protected by simple backing mats by the hooks of these backing mats being designed as double hooks and by being equipped with clamping elements reaching behind the flanges of the channel sections. A double-hook mat is thereby also created at the channel sections curved in opposite directions, the hooks of which are effectively protected against being bent open prematurely. This clamping element can in turn be designed virtually as a double hook, for which a type of chain link, for example, can be bent out of the chain-link plane. <IMAGE>
