Title: Vane cell pump
Inventor: SCHMIED GOTTFRIED
IPC: F04C28/06
Filed: 1986-04-26
Abstract: A vane cell pump (10) is proposed, which simultaneously works as a vent valve at standstill or low speed of the rotor (16). To this end, the radial displaceability of vanes (26, 28, 30, 32) arranged in slots (18, 20, 22, 24) is delayed by e.g. mechanical auxiliary means such as by spring elements (48, 64). As a result of this, a gap is formed between the vanes (26, 28, 30, 32) and the housing inner wall (14) of the vane cell pump (10), by which a continuous connection between working inlet and outlet (34, 36) is made. <IMAGE>

Title: Method for measuring the potassium contents in biological fluids
Inventor: STEINMAN GARY D
IPC: C12Q1/26
Filed: 1986-04-29
Abstract: The method for measuring the potassium concentration in a biological fluid, such as blood serum or whole blood, is carried out by fixing the amounts of phosphoenolpyruvate (PEP), adenosine diphosphate (ADP), pyruvate kinase and magnesium in the presence of a buffer in the enzymatic reaction I: <IMAGE> and measuring the rate of appearance of the products so that the reaction rate of pyruvate kinase can be determined. The reaction rate of this enzyme is directly proportional to the potassium content. The potassium concentration in the biological fluid which is to be checked is determined quantitatively by comparing the reaction rate of pyruvate kinase with a standard of known potassium concentration. The reaction rate of pyruvate kinase is preferably measured by determining the amount of pyruvate formed in reaction I by comparing the optical density of the resulting colour of the coupled reaction II and III: <IMAGE>  where     Pi is an inorganic phosphate and   In is a colorimetric indicator with at least one colorimetric standard of known potassium concentration. A paper phase method for determining potassium contents in biological fluids is likewise presented.

Title: Rotationally reversible clamping element freewheel
Inventor: FROST HEINZ-HELMUT
IPC: F16D41/08
Filed: 1986-05-02
Abstract: Seen in the axial direction, each of the clamping surfaces of the rotationally reversible clamping element freewheel represents a chord of a circle arc. This produces a surface which is symmetrical to the centre line, is of great advantage in terms of production engineering and at the same time offers the possibility of displacing the clamping elements with the aid of reversing segments in such a way that the clamping action occurs optionally both in clockwise rotation and in anticlockwise rotation under the same geometrical conditions.

Patent DE-3636248-A1 (DE)
Title: Solar chimney power station
Inventor: BUELK EGGERT
IPC: F03D9/00
Filed: 1986-10-24
Abstract: It utilises the difference between the temperature of a body of water and the lower temperature of the ambient air to operate. This temperature difference exists:     A) if frosty air lies over the ice-bound sea in winter;   B) if warm ocean currents reach regions with a colder climate; C) if the solar chimney power station is erected high above the sea on a mountain or framework.   Thus solar chimney power stations in accordance with the present invention can supply energy at the right time considerably more continuously than has been possible to date using solar or wind energy directly. But since there are only relatively small temperature differences, economically viable quantities of energy can only be supplied from tall solar chimneys. Solar chimney power stations in accordance with the present invention receive air heated not by the sun, but by the warmer waters in the solar chimney. Heat exchangers in the body of water and the solar chimney provide for the necessary transfer of temperature by means of a liquid heat transfer medium. The liquid heat transfer medium can be cycled without pumps by the thermosiphon effect. The liquid heat transfer medium can be used in a simple manner as protection against icing up of the air intake paths and of the wind turbine. One possible version is shown in the enclosed diagram (Fig. 1), where: 1. Ice on body of water, 2. Body of water, 3. Heat exchanger in body of water, 4. Pipelines, 5. Heat exchanger in tower, 6.

Patent DE-3708630-A1 (DE)
Title: Liquid-free chemistry under weightless conditions
Inventor: PLAAS-LINK ANDREAS DR
IPC: B01J19/08
Filed: 1987-03-17
Abstract: Chemical reactions with non-gaseous substances (e.g. proteins) frequently require solvents in order to allow the reactions to proceed. The invention proposes using weightless conditions in order to make liquid-free reactions possible. The reaction partners are dried in such a way that the spatial structure of the molecules is not destroyed. Enzymes or catalysts can be bound to surfaces. The concentration, distribution and transport of the substrates can be effected, e.g. by sound waves. The reactions can be activated by light, microwaves or electrostatic alternating fields. With the aid of these physical parameters, the molecular structures can also be influenced. With the aid of semi-permeable membranes, reaction chambers can be connected in such a way that coupled reactions are produced. Furthermore, crystals can be grown under weightless conditions from liquid-free dusts.

Title: Wheel drive for commercial vehicles
Inventor: REISCH JOHANN
IPC: F16H47/02
Filed: 1987-07-29
Abstract: Wheel drives for commercial vehicles which, by using a hydrostatic-mechanical split torque transmission, at constant load permit a stepless adjustment of the speed of travel, have hitherto needed too much space to be capable of being accommodated in commercial vehicles, which in their design construction are characterised by a conventional multi-stage shift transmission with a plurality of shift stages. In order to be able to accommodate a wheel drive, which permits stepless adjustment of the speed of travel, despite the limited space available, a multi-stage shift transmission (5), arranged on the output side of the hydrostatic-mechanical transmission, is designed with a stage increment in the order of approx. @ = 1.5, hydrostatic units of limited performance are used and the working speed of the hydrostatic units has a lower limit in the drive ranges IV to VI lying completely above the slip limit R. The overall volume of the hydrostatic units and hence the entire wheel drive can thereby be kept sufficiently small. <IMAGE>

Title: Gravity rotor
Inventor: ELLER ALFONS
IPC: F03B17/04
Filed: 1988-01-25
Abstract: This novel gravity rotor is to utilise gravity, with the aid of the upthrust of the water on buoyant bodies, instead of the water weight, to generate energy in such a manner that a circular rotor ring having a large diameter and circular cross-section, which consists to 10-15% of buoyant material or bodies and is guided, on the one side, by adapted rollers in a frame or the like so as to rotate vertically, is guided, on the other side, through a water basin filled with water, as a result of which that part of the rotor ring located in the water is continuously driven upwards and thus relieved and the rotor ring is caused to rotate by the equivalent excess weight produced on the other side, it being possible to drive an electric generator or other machines by means of a suitable coupling. In the case of allocation of a corresponding auxiliary water basin have a double-acting pump, water is required only once for starting up the novel gravity rotor as an inexhaustible novel energy source. The drawing shows, on sheet 1 in Figure 1, the principle of the novel gravity rotor, and the latter can also be built easily and simply in large units and numbers. <IMAGE>
