Patent DE-3143280-A1 (DE)
Title: Hydrodynamic retarder for vehicles
Inventor: HANKE HANS
IPC: F16D57/04
Filed: 1981-10-31
Abstract: In a retarder, rotor and stator blades define the outer torus of a hydrodynamic working circuit. An outlet channel connects the working circuit to a cooling circuit. Arranged on the stator are baffles to reduce the idling losses in the axial region of a gap left between the rotor and the stator and these can be displaced between a rest position outside the flow of the working circuit and an obstructing position, in which they are at least partially in the flow of the working circuit. In order to obtain low-loss conversion of specific kinetic energy into pressure energy without interference from the baffles at the inlet of the outlet channel into the working circuit, the outlet channel is of spiral design, opening into the gap tangentially to the rotor-side portion of the outer torus. The stator has a core ring lying approximately centrically within the outer torus. The baffles are arranged on the core ring and, in the rest position, lie within the radial region of the core ring.

Patent DE-3149536-A1 (DE)
Title: High-temperature reactor having a core of spherical fuel elements
Inventor: HARDER HERBERT DR
IPC: G21C1/07
Filed: 1981-12-15
Abstract: The subject-matter of the invention is a control and shutdown system for a high-temperature reactor having a core of spherical fuel elements, which system comprises absorber rods (reflector rods) that can be inserted into openings in the side reflector, and absorber rods (core rods) that can be inserted into the core. A portion of the reflector rods forms a first shutdown system for the partial or rapid shutdown, while the other portion of these rods undertakes control functions. The core rods form a second shutdown system for the complete or long-term shutdown. In order to limit damage effects in the event of a reactivity accident, the portion of the reflector rods serving for control is subdivided into two rod groups (for fine control and for fast load control), which are moved at a different speed and with different excess reactivity, and for the absorber rods of the first and of the second shutdown system the withdrawal speed is fixed lower by a multiple than the insertion speed. The ratio of the two rod speeds is chosen such that in an accident enough time remains to initiate emergency measures even in the event of failure of rapid shutdown.

Title: Method for operating DC and AC locomotives on model railway systems, and apparatus for carrying out this method
Inventor: LEISNER ROBERT
IPC: A63H19/24
Filed: 1981-12-15
Abstract: In order to operate DC locomotives and AC locomotives equipped with movement direction switches on a model railway system which is designed especially for operation of the latter, the speed of movement for both types of locomotive being varied by the magnitude of the output voltage of one and the same transformer and the direction of movement being varied by producing an excess-voltage pulse in said transformer, it is provided that the voltage extracted from the transformer at its movement current output is emitted rectified in one operating condition from an intermediate apparatus connected between the transformer and the rail system, that the excess-voltage pulse causes a change in the polarity of the rectified voltage, and that, during the occurrence of this pulse, on the one hand the emission of DC voltage is suppressed and on the other hand this pulse is emitted in a form which is suitable for operating the movement direction switch. Operation of DC and AC locomotives on one system is thus possible without locomotives having to be re-equipped - apart from matching one type of locomotive to the respective other rail system with respect to the current pick-off from the rails.
Patent DE-3149890-A1 (DE)
Title: Dippable interior rearview mirror for vehicles
Inventor: REINHARDT JUERGEN
IPC: B60R1/08
Filed: 1981-12-16
Abstract: A dippable interior rearview mirror for vehicles having a housing which is mounted on a mirror holder so as to be swivellable about a tilting axis running parallel to the mirror surface and which bears the mirror plate and having a tilting lever which is mounted on the housing at a distance from the tilting axis so as to be capable of being moved into two limit positions about an axis parallel to said tilting axis and is supported against the mirror holder, by means of which tilting lever two adjustment elements can be moved, each of which engages in each case in one control channel whose one boundary face is constructed on the mirror holder and whose other boundary face is constructed on the housing. In each control channel, a ramp surface is constructed as a junction between an extended control channel section and a locking section which is constricted with respect to the latter. As a function of the tilting position of the mirror housing with respect to the mirror holder, the maximum width of the locking section is dimensioned in such a way that the locking section can hold the adjustment element. The movement of the adjustment elements is opposed in such a way that one adjustment element is located in the locking section and the other adjustment element in the extended control channel section. When the tilting lever is moved over, the one adjustment element leaves the locking section and thus permits a swivelling movement between the housing and mirror holder, which movement is brought about by the other adjustment element which runs on the path from the extended control channel section into the locking section and onto the ramp face.

Patent DE-3200474-A1 (DE)
Title: Electrical flow heater
Inventor: HILLINGER ERICH
IPC: F24H1/10
Filed: 1982-01-09
Abstract: In electrical flow heaters equipped with tubular heaters for liquid media not only is a good, as loss-free as possible heat transfer between the tubular heater and the medium to be heated required but said heat transfer is also required to be as uniform as possible, i.e. that no excessively high surface loadings occur which result in stiff lime encrustations which in turn reduce the service life of the heater or even result in malfunctions in the device concerned. These requirements are fulfilled in the novel flow heater by making the flow tube of the heater from an outer tube and an inner tube of smaller diameter, placing one or more tubular heaters between the walls of these tubes and embedding them in a metal powder, and by compressing this structure into a unit under high pressure, thus highly compacting the metal powder, and by installing this structure as a heating insert in a larger container used to convey the medium to be heated.

Patent DE-3238236-A1 (DE)
Title: Fire-protection glazing
Inventor: DOMNICK ARNO
IPC: E06B3/964
Filed: 1982-10-15
Abstract: In fire-protection glazings crucial importance is attached to the fitting of the fire-resistant glass panes in the clamping frame, since otherwise the prescribed function is not guaranteed in the event of fire. The risk of assembly errors is avoided using a clamping frame whose construction determines the glass-fitting, the frame on the one hand providing a solid planar bearing shoulder for the pane and on the other hand a limiting shoulder for a contact strip (glass bead). The pane is advantageously fixedly connected to a surrounding glass strand for sealing and edge protection, the strand causing the pane to be held more reliably in its mount. Additional assembly aids make it possible to supply a clamping frame not only separate from the pane but also in ready-to-assemble elements so that simple but precise assembly at the place of installation is possible.

Title: Process for producing waterglass-bound mouldings
IPC: C04B28/26
Filed: 1982-12-16
Abstract: A process for producing mouldings from inorganic materials, especially foam granules, is described, which are bound with waterglass. The inorganic materials, for example foamed glass or the like, are mixed with an aqueous waterglass solution, moulded and then dried. Metal oxides or minerals of a type which does not precipitate the waterglass are added to the waterglass solution. The mouldings produced from the mixture are then reactively dried at an elevated temperature and subsequently cooled down slowly. The additives used are especially zinc oxide, iron oxide, red mud, alumina, clay, mica or quartz powder. The grain size of the metal oxides or minerals should be below 100  mu m for up to 90% of these materials. The reactive drying is carried out by treating the mouldings with hot gas from 150 to 700 DEG C, preferably 200 to 500 DEG C.
