Patent DE-3238598-A1 (DE)
Title: Device for the compression of fluids, even during the liquid <--> solid phase transition, by means of a spring bellows made of viscous or viscoelastic materials subjected to internal pressure
Inventor: SCHMIDT JOACHIM DIPL ING
IPC: B22D27/09
Filed: 1982-10-19
Abstract: Since, during the liquid <- solid phase transition in metals, a so-called negative volume jump generally arises, cavities (shrinkage and gas bubbles) occur in the solidified casting. In order to avoid such defects, Takahashi has disclosed a piston-spring system. Here, a helical spring prestresses a piston which, for its part, keeps the melt under pressure. The invention for which protection is sought here makes it possible to prevent the abovementioned casting defects in a manner different from that disclosed by Takahashi: The subject-matter of the invention is a viscoelastic spring bellows (with controllable internal pressure) for the compression of fluids (melts). This spring bellows is capable of operating at very high temperatures (e.g. the casting temperatures of the particular alloy).   In a predetermined temperature range, the initially rigid envelope (e.g. a glass envelope) around a volume of gas becomes viscoelastic. This makes possible creep and flow and, at a sufficiently high internal pressure (affected by the initial pressure and the temperature of the spring bellows), the required "spring action" is obtained. The invention can be employed   - in the melting and solidification of metals, nonmetals and combinations thereof (so-called composites), - in the production of highly stressed components, e.g. in the fields of biomedical technology and aircraft propulsion systems (see also sketch).   <IMAGE>

Title: Water supply heater operable with district heat as heating medium
Inventor: ROBIONEK HANS-JOACHIM
IPC: F24H1/20
Filed: 1983-04-27
Abstract: The water supply heater (1) has an internal heat exchanger (4) which has a heating surface section (40), connected to the feed (6), dipping into the interior space (3) of the storage container (2), and which is in direct heat exchange with the service water. A heating surface section (41) forming part of the heat exchanger (4) and leading to the return is arranged in a preheating chamber (11). The cold water is introduced via a cold water feed (5) into the preheating chamber (11) at the cold side and flows through the latter (11) against the flow direction of the district heating medium, the cold water being heated by uptake of heat from the heating surfaces in the preheating chamber (11). The preheated cold water is introduced through an opening (16), remote from the entry point, of the preheating chamber into the interior space (3) of the container. The district heating medium is thus cooled to close to the entry temperature of the cold water, and the heat withdrawn from the district heating medium is mainly used for hot-water preparation. <IMAGE>

Title: Sun visor on a rearview mirror
Inventor: HEUCKMANN ROBERT
IPC: B60J3/02
Filed: 1984-06-19
Abstract: The "sun visor on a rearview mirror" with pull-out anti-dazzle film constitutes an additional protection against dazzle for the drivers of motor vehicles, which, attached to the holder of the rearview mirror by means of a clamping device, is intended to protect, as a connecting visor between the folded-down, permanently installed car sun visors which are installed to the left and to the right of the said connecting visor, the unprotected intermediate space against the dazzle effect. Thus, almost the entire field of vision of the driver located in the entire width of the windscreen is screened uninterruptedly by means of this further sun visor. This rearview-mirror sun visor consists of a very flat, rectangular, darkly coloured polycarbonate/macrolon housing and a pull-out 1 mm thick anti-dazzle film made of the same material. In the clamped-tight state, this sun visor is located between the rearview mirror and windscreen and in the pushed-up state it is located directly against the upper edge of the said windscreen and therefore, in accordance with the safety regulations of the STVZO (road safety organisation), lies outside the impact angle in the event of accidents. Since different types of vehicle have rearview mirrors attached to the windscreen, a rectangular recess was made on the upper central part of the housing, in the grooves of which recess the housing can be pushed upwards on a rail attached to the swivellable clamping device, past this rearview-mirror holder which is less common. In this way, this visor can be pushed up and down in two respects ...   Original abstract incomplete.

Title: Elastic bearing for a tiltable driver's cab of a lorry
Inventor: ZAWADZKI BERND DIPL ING
IPC: B62D33/067
Filed: 1985-02-19
Abstract: The invention relates to an elastic bearing for a tiltable driver's cab of a lorry with a housing (5) with receptacle eye (6) which is attached to the chassis frame of the lorry and lies axially transversely with respect to the vehicle axle. Central metal components (7, 8) which are connected to the housing (5) via rubber elements (25) extend into the housing. The rubber/metal adhesive faces of these rubber elements (25) are located in the direction of the vehicle axle and in approximate vertical alignment so that the rubber elements are loaded in shear in the case of vertical spring compression and loaded in tension or compression in the case of transverse deflections. The metal parts (7, 8) bear rubber stop buffers (28, 29) in the region of the receptacle eye both in the vertical direction, downwards and upwards, and in the horizontal direction, in and counter to the direction of travel. The rubber elements (25) are configured in such a way that in the case when they are loaded statically with the driver's cab, the rubber stop buffers (28, 29) do not rest against the inside of the receptacle eye (stop face 30) but, rather, intermediate spaces (31, 32) are formed. Therefore, the bearing in the vertical direction and in the direction of travel is relatively soft due to the shear stressing of the rubber elements (25) until the rubber stop buffers (28, 29) come into contact with the stop face (30), which leads to a more rigid bearing and limiting of deflection. <IMAGE>
