Patent DE-3136873-A1 (DE)
Title: Prefabricated reinforced-concrete shell
Inventor: SILBERKUHL JUN WILHELM DIPL KF
IPC: E04B7/10
Filed: 1981-09-17
Abstract: The invention relates to a prefabricated reinforced-concrete shell which is rectangular in outline, is curved in the form of an arc in longitudinal section and, in cross-section, is curved symmetrically in the form of a channel or in the form of a V, with respect to the longitudinal axis, having curved V-legs. The shell is reinforced with reinforcing mats and tensioning elements which run, with a predetermined tensioning force, from shell end side to shell end side and are embedded in the reinforced-concrete body. The reinforced-concrete body is set up and designed to be mounted, in the region of the shell end sides, on bearing means which are to be arranged. The reinforced-concrete bodies are prefabricated, with the embedded tensioning elements in the form of non-interconnected individual tensioning members, as reinforced-concrete bodies which have untensioned reinforcement and a predetermined longitudinal curvature corresponding to the shuttering. The individual tensioning members each comprise a tension member and a sheath which is embedded in the reinforced-concrete body and in which the tension member can be displaced. The tensioning is, however, such that the reinforced-concrete body is excessively curved, with respect to the longitudinal curvature predetermined by the shuttering, by the tensioning force of the individual tensioning members. Excessive curvature is intended to mean an arcuate curvature, the curvature radius of which is smaller than the curvature radius of the longitudinal curvature corresponding to the shuttering. <IMAGE>

Title: Cleaning machine
IPC: B01L99/00
Filed: 1981-10-29
Abstract: A cleaning machine, in particular for hoses (11) for use in laboratories or hospitals, has a rotatable drum (6) which has at least one plug-on or connection nozzle (9, 10) which rotates with the drum and can be connected to a cleaning water supply (2, 3, 4, 5). The cleaning water emerges from the plug-on or connection nozzle(s) (9) and flows through the hose or hoses (11) which are coiled around the outside circumference of the drum (6) and attached to it. The drum (6) is rotated during the entire cleaning operation by the water emerging at the other ends of the hoses (11) and, if appropriate, by additional rotating devices (12, 13, 14, 15). For a drying operation, filtered and, if appropriate, heated pressurised air from the plug-on or connection nozzles (9, 10) can be passed through the hoses (11). <IMAGE>

Title: Switching levers mounted in the front part of a handlebar
Inventor: LANNOCH HANS-JUERGEN
IPC: B62M25/04
Filed: 1981-11-14
Abstract: The invention relates to an arrangement and mounting of switching levers for a derailleur. The two switching levers usually required for a derailleur are mounted according to the invention in the front part of the handlebar of a bicycle, specifically the axes of rotation of the two switching levers run flush with one another and parallel to the axis of rotation of the front wheel of the bicycle. This arrangement of the switching levers and their mounting permit a harmonic integration into a component which is already present. In addition, the operation of the switching levers is particularly convenient since the distance between them and the respective ends of the handlebars is very small. Furthermore, only a small expenditure of force is required for switching since the movement of the switching levers takes place away from the cyclist or towards the cyclist.

Title: Turnover plough with a cutting-width adjustment to be actuated during ploughing
Inventor: ALBERS HEINRICH
IPC: A01B3/421
Filed: 1982-05-18
Abstract: For ploughs, in which, before each turn of the plough bodies, the centre of gravity is displaced into the ideal axis of rotation and, after turning has occurred, is displaced back into the working position again, corresponding switching elements are inserted into the hydraulic circuit for the purpose of the automatic execution of this operation, so that under special conditions, such as in alternating ploughing uphill and downhill, a displacement of the plough frame is possible during ploughing, and at the same time excluding the possibility that a rotation of the plough frame will commence. This is achieved by means of further feed conduits (40, 41) which are installed in addition to the first two feed conduits (38, 39) and to which are connected the connections (34, 35; 31, 32) of the conduits (36, 37) connecting the displacement cylinder (15) and turning cylinder (30) to one another. The points (47, 48) of the connection of the second feed conduits to the conduits (36, 37) are located nearer to the displacement cylinder (15) than the connection points (46, 49) of the first feed conduits, there being inserted into each of these connecting lines, between the respective connections (47, 48) of the first and (46, 49) of the second feed conduits, a non-return valve (47, 51), by which the valve (50) assigned to the piston side of the displacement cylinder is controlled. A pressurising valve (52) is connected in parallel with the non-return valve assigned to the piston-rod side of the displacement cylinder. <IMAGE>

Title: Rotary piston machine
Inventor: WERNER RUDI
IPC: F01C3/08
Filed: 1982-06-11
Abstract: The subject of the invention is a rotary piston machine, in which two bevel gears, arranged at an obtuse angle with respect to each other and fitted with at least two pyramid-like teeth each, the curved head face or head face edges of which slide, during the turning of the bevel gear, alternately along one of their two neighbouring tooth flanks in a sealing manner, are mounted rotatably only about their axes in a housing with a spherical or hollow-spherical working space, the spherical limiting face/faces of which has/have the bevel gear axial meeting point as centre point and bears tightly against the bevel gears as well as the axially remote, convex and the axially close, concave face of each tooth, so that during the turning of the bevel gears working chambers of changing volume are produced, into which substances flow in and out through inlet and outlet windows, which are formed in the working space limitation of the housing. This machine can be used as a pump, compressor, power converter of pressurised substances (Figs. 22-24) and as a four-stroke (Figs. 1-4) or two-stroke internal-combustion engine (Figs. 25, 26), in which the ratio of the intake/compression chambers to the working/exhaust chambers is also able to take different values. <IMAGE>

Title: Wall cabinet, in particular for accommodating a heat counter and fitting unit
Inventor: URBAN RUDOLF F
IPC: F24D19/10
Filed: 1982-08-02
Abstract: A wall cabinet, in particular for accommodating a heat counter and fitting unit, consists of a frame with a bottom constructed integrally thereon and a top which can be attached to the frame by means of retaining elements, preferably magnetic fasteners. The flow and return pipes with installed fittings are attached to the bottom of the wall cabinet by means of clips or the like. The wall cabinet is manufactured from a formable, sound-insulating and fire-resistant material, preferably asbestos cement. According to a preferred embodiment, the wall cabinet contains a partition for division into a first region for receiving pipes and fittings which give off heat and a second region for receiving electronic components, for example a counter. In a wall cabinet of this type, the imposition of heat on the electronic part is largely ruled out and, furthermore, circulation is ensured by openings in the top to avoid overheating of the electronic parts. A wall cabinet of this type has extremely good sound-insulating properties and can readily be covered with wallpaper, painted and clad in any other manner.

Title: A toothed wheel
Inventor: HAUMAIER ANTON DIPL ING
IPC: B62D53/00
Filed: 1982-11-23
Abstract: A toothed wheel or toothed segment is fixedly attached to one of the two sub-vehicles of an articulated vehicle, the axle of said wheel or segment being flush with the swivel axle of the connection gantry between the two sub-vehicles and said wheel or segment facing the other sub-vehicle. The gantry carrier has an arm which bears at its end a pinion which engages on the one hand with the toothed segment or toothed wheel and on the other hand engages in a chain or a toothed belt, which chain or belt is attached to another sub-vehicle in an approximately arcuate shape in such a way that said chain or belt is constantly wrapped around the pinion with pretensioning. This transmission connection is of very flat design and ensures in a simple manner with a low servicing requirement that the gantry carrier is always aligned approximately longitudinally with respect to the angle bisector of the bending angle between the two sub-vehicles.
