Title: Floating apparatus with oars for forward propulsion
Inventor: MUELLER WALTER
IPC: A63B35/06
Filed: 1986-05-14
Abstract: In a square guide pipe, two sliding strips are arranged opposite each other and are connected to each other in a non-positive manner at the ends by cables deflected over rollers. Attached to each sliding strip is a pedal, the pedals sliding in lateral slits in the guide pipe. Attached to the lower end of a sliding strip is a drive angle which pivots two opposingly mounted angled levers backwards and forwards relative to each other. When this takes place, the swinging oars are moved in the water on the long oar legs, as a result of which hydrodynamic forward propulsion occurs. In this floating apparatus, short and linear pedalling strokes by the legs are converted via the angled levers into large pivot ranges of the oars. The apparatus is customarily held by the handle during swimming. It can however also be strapped with a belt. This principle could certainly also be applied for the forward propulsion of small boats.

Title: Mirror, especially vehicle rear-view mirror
Inventor: HAAG GUENTER DIPL PHYS DR
IPC: B60R1/08
Filed: 1986-07-18
Abstract: The invention relates to a car rear-view mirror, in the case of which a special arrangement ensures that the region which cannot be viewed by the driver of the vehicle, the so-called blind angle, is eliminated to a substantial extent. This is achieved in that part of the car rear-view mirror is divided up into a number of parallel segments which are metal-coated and which are inclined with respect to one another in such a way that the optical effect of a convex mirror is simulated, preventing the existence of non-viewable regions. The invention can be applied in vehicles, in the advertising sector or to produce special optical components. <IMAGE>

Patent DE-3700122-A1 (DE)
Title: Chamber for separating a particle mixture according to the countercurrent centrifugation method
Inventor: LUTZ MANFRED
IPC: B04B5/04
Filed: 1987-01-03
Abstract: In counterstream centrifugation technology, in addition to the centrifugal force, forces of a centripetally directed flow of liquid act on a mixture of particles. An equilibrium of forces is established as a function of the size and density of the particles. By changing the force ratios, particles of different sizes and density can be isolated from the liquid flowing off in centripetal fashion. The geometric profile of the separating area, the so-called separating chamber, is decisive for the selectivity of separation. By virtue of eddy effects of the liquid flow and by virtue of non-uniform distribution of flow, the separation selectivity is unfavourably influenced in previously known separating chambers. In the described separating chamber, a uniform flow behaviour and a uniform distribution of the particles in the separating chamber are achieved by means of a central inlet opening which is aligned in the longitudinal direction of the chamber and by means of a constantly increasing cross-section of the chamber. As a result, the precise, non-damaging separation of large amounts of a mixture of living cells is made possible.

Patent DE-3708940-A1 (DE)
Title: Hydraulic drive for aerial lift devices (cherry pickers) or the like
Inventor: KREMER ERWIN DIPL ING
IPC: F04B49/00
Filed: 1987-03-20
Abstract: A hydraulic drive for aerial lift devices (cherry pickers) or the like includes a first pump having a pressure balance integrated or in the incoming line, and an output line that can be connected to one or more consumers. This output line is connected to the control input of the pressure balance via a branched control line; in zero-lift operation, the pressure balance controls the first pump to a stand-by mode with a small residual pressure. Furthermore, a second pump, like a hand pump, is provided, that has a small capacity compared to the first pump, and is connected to the output line of the first pump. It is intended to improve such a hydraulic drive by the controlling of the pressure balance via the control line being possible only when the first pump is in operation, including in stand-by mode, and by preventing a flow of hydraulic fluid from the discharge end of the second pump into the control system of the first pump when the hydraulic system is being supplied via the second pump. For this purpose, a hydraulically deblockable non-return valve is located in the control line; its control input is connected to a section that can be blocked against connection of the second pump by a non-return valve, and its releasing pressure is lower than the residual pressure of the first pump in stand-by mode.

Patent DE-3714242-A1 (DE)
Title: Warm water basin
Inventor: KAYSER BURKHARD
IPC: E04H4/00
Filed: 1987-04-29
Abstract: The hitherto conventional whirlpools comprising integral plastic basins have only a small water volume at high water temperatures and therefore present bacterial problems. They do not have any clearly defined sitting and/or lying zones, so that the users can easily disturb one another. There is provided a basin which comprises principally any plurality of individual elements (1, 10) with a predetermined number of formed seats (2 to 5) or with a formed reclining zone (11) which are each arranged next to one another and around a basin bottom (12) and are closely connected to one another and to the basin bottom (12). This results in defined use zones with a predetermined number of users in conjunction with a free water zone forming above the basin bottom, and this leads overall to a volume of water sufficiently large for the concentration of contaminants to be reduced. The principal structure is characterized by being extremely variable and thus adaptable to the spatial circumstances and the intended number of users. Such warm-water basins are particularly suitable for use in public facilities. <IMAGE>

Title: Process for the production of powder material
Inventor: MICKELEIT MICHAEL DR
IPC: C01F7/30
Filed: 1987-09-03
Abstract: In a process for the production of powder material, in particular of fine-grained powder for the manufacture of high-performance ceramics, the starting material is dissolved or dispersed in a liquid and this suspension is applied dropwise to an ultrasonic transducer head where it is atomised to form an aerosol. A transport gas conveys the aerosol into a heating region where the aerosol is evaporated. The solid particles crystallising out are then separated off from the gas phase as an extremely fine-grained powder. An apparatus for carrying out this process comprises a process chamber in which are arranged an ultrasonic transducer head having a feed unit for the suspension, inlet orifice for the transport gas, a heating device and a separator. <IMAGE>

Patent DE-3744226-A1 (DE)
Title: Fuel-feed system
Inventor: HOFBAUER PETER PROF DR
IPC: F02M37/12
Filed: 1987-12-24
Abstract: Fuel-feed systems of this type are required for internal-combustion engines installed in motor vehicles and have a pre-feed pump. Mechanical fuel pumps are arranged on the internal-combustion engine and, as a rule, have an excess quantity which can be pressurised, with the result that a considerable increase in the feed energy for the fuel pre-feed can be achieved. For this purpose, the new system has the features that excess quantity is fed into a fuel line by a valve, that the excess quantity enters connecting channels via a pressure channel and a pressure valve and loads a stepped-piston pump, that, during the adjustment of the stepped piston, fuel is fed into a pressure accumulator and the fuel-feed pressure thereby loads a differential-pressure setter which opens and closes connecting lines between the feed chambers and the pressure accumulator and the working chambers, that piston ends of the stepped piston have a channel which connects the working chamber to the adjacent feed chamber and in which are arranged valves which, when they approach housing extensions, jump over and thereby force the other valve out of the position closing the channel into a position opening the latter, and that, during the fuel-pump suction phases, the fuel stored in the pressure accumulator is forced into the fuel line. By preventing gas bubbles in the suction line of the pump, [lacuna] are [lacuna] more reliably [lacuna] ... Original abstract incomplete.

Title: Arrangement for introducing bending or counterbalance forces into axially displaceable rolls of a rolling stand
Inventor: BENNER FRANK
IPC: B21B31/20
Filed: 1988-01-27
Abstract: When the rolls are displaced axially, bending or counterbalance cylinders of rolling mills are subjected to high horizontal forces which tilt the pistons in the cylinders. The proposal is to arrange a single-armed lever between the pistons of the bending or counterbalance cylinders and the corresponding chocks, this lever being able to divert the horizontal forces into the housing, thereby preventing the pistons of the bending or counterbalance cylinders from tilting.
Patent DE-3806502-A1 (DE)
Title: High-pressure pump for non-lubricating fluid and for pressures exceeding a thousand atmospheres
Inventor: EICKMANN KARL
IPC: F02B3/06
Filed: 1988-03-01
Abstract: In pumps for non-lubricating fluid with delivery pressures exceeding a thousand bar, there is the problem that the service life is limited by the number of strokes of the separating parts and valves. Such pumps therefore have a low speed in order to achieve a sufficient hourly operating figure. Since the primary drive units, such as diesel engines or electric motors, run at high speeds, expensive and voluminous reduction gears were necessary, the service life of which was likewise limited and which, despite their high costs, caused noise and operational unreliability. The invention overcomes these difficulties in that it allows a distributor to rotate at low speed, which distributor then conveys pressure fluid to the high-pressure pistons - mostly with a medium-pressure piston intermediate stage - so as to allow the valves and separating means, such as the diaphragms, V-elements and the like, to work with a small number of strokes per unit of time. In the case of other embodiments, the distributor is replaced by sequence signals which initiate the next piston immediately after the end of the pressure stroke of the previously forcing piston. Furthermore, details which promote the simplicity or the service life are described.

Title: Pressure disc for a flexible driver plate
Inventor: SCHREINER FRIEDRICH
IPC: B60K17/00
Filed: 1988-08-11
Abstract: A pressure disc (1) for a flexible driver plate (3) which is arranged between an engine shaft (4) and an input member (5) of a gearbox has holes (12) distributed uniformly on the circumference at a defined diameter (18) close to the central bore (11). Bolts (2) are used to fasten a driver plate (3) to the front end of an engine shaft (4), the contact pressure being applied via the bolt heads (21) and the pressure disc (1). The pressure disc (1) is configured in such a way that the pressure is virtually uniform over the entire contact or pressure surface (14) relative to the driver plate (3). For this purpose, the cross-section (15) of the pressure disc has a defined configuration. In particular, it is thickened to such an extent to the outside of the bolt heads (21) that the pressure at the pressure surface is similar in this area during operation to that in the area of the bolt heads (21). In addition, the pressure surface (14) can be of conical configuration, so that the prestress outside the area of the bolt heads (21) is initially slightly greater. A ring of more flexible material can furthermore be inserted close to the outside diameter of the pressure disc or the pressure disc can be provided with a wavy outside diameter which follows the bolt heads. <IMAGE>
