Patent DE-3401833-A1 (DE)
Title: Solar seawater desalination plant
Inventor: MUELLER WALTER
IPC: C02F1/14
Filed: 1984-01-20
Abstract: The plant depicted in Figure 1 is composed of a tower shaft (1), around which are arranged, in a star-shaped and vertical manner, condensation chambers (21) which form the condenser (2). The condensation chambers (21) are connected at the top to the tower shaft (1) by chamber bends (7). At the bottom, a transparent canopy (4) and a partition roof (6) are connected to the condensation chambers. At the periphery, the canopy (4) is furnished with a turnround (5) and a condensate deflector (24). The partition roof has a ring collector line (25) at the periphery. It is arranged flat over the water and forms the circular evaporation chamber (14). The heating tank (15) is connected to the turn round (5) and is surrounded by a barrier (18). Channels (16) lead from the outer rim of the heating tank (15) in a star shape to the intake opening of the impeller (13). The rotor (11) is located in the chimney (9) and is connected to the impeller (13) by the rotor shaft (12). The condensate vessel (23) is arranged at an expedient height. In the plant, air circulates in the closed circuit by its own convection, taking up vapour and heat in the evaporation chamber (14) and being cooled again in the condenser (2). The external air, as a result of heating, ascends between the condensation chambers (21) in the condenser (2) and, via the rotor (11), drives the impeller (13) which circulates the salt water. <IMAGE>
Patent DE-3401885-A1 (DE)
Title: Rotary shaft slot control for controlling the fresh and exhaust gases of piston-driven four-stroke internal combustion engines
Inventor: LEERS ROLF-PETER
IPC: F02B75/02
Filed: 1984-01-20
Abstract: The invention relates to a rotary shaft slot control in the fresh gas feed and exhaust gas discharge area of all piston-driven four-stroke internal combustion engines. The invention is suitable for replacing conventional valve control. The rotary shafts each have an inlet and/or an exhaust slot in the cylinder area. Depending on the type of engine these shafts have a certain ratio to one another, and in the ratio 1:4 are controlled directly by the crank shaft by way of chains and gears, the smaller gear being flange mounted on the crank shaft. This method of control is suitable for significantly increasing the engine speed without the disadvantages characteristic of valve control, such as valve spring breaking or valve fracture, being able to occur. Owing to the essentially larger slot cross section, the delivery on inlet and exhaust is considereably increased. In addition this system results in an improved, more accurate control, since tappet clearance no longer impairs the control. The inlet and exhaust slot side walls can also be reinforced by stability lands, so that the pressure occurring during the working stroke is better absorbed.

Title: Motor vehicle
Inventor: APER LUDWIG
IPC: B62D25/00
Filed: 1984-04-18

Title: Swivel screen
Inventor: SCHICK HANS
IPC: E02B8/02
Filed: 1984-05-24
Abstract: In the case of a cleaning screen for collecting and removing screenings in hydraulic engineering installations, a swivel screen rotatable about a horizontal axis is arranged in a channel. The swivel screen has two screen surfaces, rotatable with one another and firmly allocated to one another, and a positive-cleaning device coming into engagement with at least one of the two screen surfaces of the swivel screen during its rotation. The swivel screen is preferably a hollow cylindrical or partly cylindrical rotary body which is mounted at the closed end faces in the channel side walls. The partly cylindrical circumferential surface consists of a cylinder-sector-shaped screen surface and a cylinder-sector-shaped solid wall surface, both of which, at the circumference centre, are at a distance from one another in the form of a free opening for the unimpeded flow of the water. Furthermore, a positive-cleaning device is allocated to the circumferential surface. When the swivel screen is rotatated, the positive-cleaning device reaches in between the screen bars of the curved screen surface and cleans it.

Patent DE-3429542-A1 (DE)
Title: Adjustable hydrostatic pump
Inventor: GRIESE KLAUS DIPL ING
IPC: F04B49/12
Filed: 1984-08-10
Abstract: The adjustable pump designed as a radial piston pump has a cam ring (11) for setting the piston travel. The adjusting force is produced by a servo piston (12) acted upon by a second piston (26) controlled via a hydraulic regulator (24). The adjustable pump conveys a medium which, because of its chemical properties, must not be brought into contact with the pressure medium which is used in the hydraulic regulator (24) and which actuates the piston (26). Thus two different media are present which, in particular, are separated by two sealing rings (39, 40) which bear on the piston (26). In this way, a trouble-free and economical operation of the pump is achieved. Hitherto it had been necessary to use mechanically adjustable pumps for applications like these. <IMAGE>

Title: Push-in barrel for a gun
Inventor: FRITZ BERNHARD
IPC: F41A21/10
Filed: 1984-12-18
Abstract: A push-in barrel for a hunting weapon is held in the firing chamber of a shotgun barrel of the same and is connected to an intermediate barrel which is supported in the choke tube, at the muzzle end, of this shotgun barrel. An adjusting device, which acts between the intermediate barrel and the push-in barrel, is arranged approximately in the centre of the barrel, and the muzzle end of the push-in barrel carries a muzzle support, especially a muzzle plate, which supports the push-in barrel in the radial direction but such that it is mobile in the axial direction. As a result of the three-point support of the push-in barrel which is achieved in this way, the oscillation behaviour is considerably improved, the deformation of the barrel is distributed over its entire length, and the wall thickness of the intermediate barrel can be selected to be significantly thinner. The axial mobility of the muzzle support at the same time ensures unimpeded heat movement of the push-in barrel in the axial direction. The muzzle support, which preferably rests in a sealing manner in the intermediate barrel, prevents the ingress of dirt and moisture into the space between the push-in barrel and the intermediate barrel.

Patent DE-3511283-A1 (DE)
Inventor: BOENISCH DIETMAR PROF DR ING
IPC: B22C15/00
Filed: 1985-03-28
Abstract: Foundry molding material is poured or pneumatically infed into a mold frame arrangement containing at least one pattern, a molding frame and a filling frame. Subsequently, the foundry molding material is compacted by a compacting arrangement containing, for example, any one of a compressed-air surge compacting device, a combustion-force surge compacting device, a pressure compacting device, a vibrational compacting device or a combined pressure-and-vibrational compacting device. Also during such compacting operation at least the predominant portion of the foundry molding material contained in the filling frame is displaced into the molding frame. During such compacting operation a preselected expanding gas is infed into predetermined local regions of the foundry molding material while such material is being compacted. As a result, there are formed zones of reduced packing density in the foundry molding material. During the further compacting operation, but in any case at the end of such compacting operation, the zones of reduced packing density are eliminated and the packing density of such zones is at least approximately equalized with the packing density prevailing in the remaining zones of the foundry molding material.
