Title: Heat exchanger for a condensing or evaporating medium and a medium without phase transition
Inventor: BOSSEL ULF DIPL ING DR
IPC: F28D7/10
Filed: 1983-01-13
Abstract: A heat exchanger for a condensing or evaporating medium, e.g. coolant, and a medium without phase transition has a housing (1) in which flow paths (6, 9) are provided for the two media and which are separated from one another by filling (11), which as a rule has fins (10) or grooves and through which the heat that is to be transferred flows due to thermal conduction. So that as large as possible a surface of the heat exchanger is used for the phase transition, the flow path (9) for the medium without phase transition is subdivided into a multiplicity of relatively short component flow paths (14) to which approximately the same quantity of medium is applied. The component flow paths (14) are led parallel to one another in the housing (1) due to the construction and arrangement of the filling (11) which transfers the heat. The faces of the filling (11) which delimit the component flow paths (14) with respect to one another are approximately of the same size in order to achieve constant temperatures along the flow path (6) of the medium with phase transition.

Title: Spray and conveyor apparatus for dry material in powder or granule form for building construction and industry
Inventor: MESSINA P O VITTORIO
IPC: B05B7/14
Filed: 1983-03-31
Abstract: The apparatus has a higher-placed rotary distributor drum into which compressed air is introduced in order to correspondingly spray the material, if necessary with the addition of water, through the outlet opening. In each case two seals are provided, between the hopper and the drum and between the drum and the lower part of the machine, to prevent escape of the material but to permit movement of the parts. The closure system includes at least one cylinder-piston unit which is fed either from the pressure source of the apparatus itself, or by the use of hydraulic oil from a corresponding plant, and which exerts a constant pressure on the seals and thus also prevents escape of the material when the latter is used up. The closure system proposes dampers, if necessary, in the form of springs which are offset 90 DEG from the piston in order to distribute the applied pressure uniformly.

Title: Key-pressure initiator
Inventor: MOTSCH ALFONS DIPL ING
IPC: H01H13/52
Filed: 1983-10-26
Abstract: The key-pressure initiator described here has the object of optionally initiating electric-motor, pneumatic or hydraulic operations on an electronic or weak-current electrical basis, such as opening and closing doors, calling lifts or the like, the priority being, however, the opening of doors on public transport means. The key-pressure initiator primarily offers the advantage for such purposes of the extremely short switching movement of a film surface switch without the disadvantageous safety risks which were previously linked thereto. Neither vibrations of a railway carriage during movement nor weather-related or other external influences can cause inadvertent switch operations. At the same time, the construction of the initiator is extremely simple and has no mechanically moving element. The initiator is thus correspondingly cost-effective, has a virtually unlimited life and requires virtually no repairs or maintenance. <IMAGE>

Title: Steering mechanism for model road vehicles on a 1:87 scale
Inventor: KOCH STEFAN
IPC: A63H18/10
Filed: 1984-03-19
Abstract: The most essential criterion for a steering mechanism for model road vehicles is that, in each case, it controls a vehicle by means of forces acting on the latter from outside. This is particularly the case, so far as vehicles as accessories for 1:87 scale model railways are concerned, in accordance with the state of the art which has now been reached, in that the criteria of faithfully reproduced external appearance, versatility in use corresponding to the original and a simple system structure which can be operated by anyone, which criteria are important for a model layout, still always suffer from too many concessions. These problems can be solved by a magnetically driven vehicle steering mechanism in which an iron wire, running below a thin road covering and invisible from above, traces, through the road covering, a magnet which forms part of the vehicle steering mechanism and drives the vehicle's front wheels via a lever linkage.
