Patent DE-3617365-A1 (DE)
Title: Method and device for driving a shaft
Inventor: RAU RUPERT
IPC: F01B3/00
Filed: 1986-05-23
Abstract: In a method for driving a shaft, for example an output shaft of a motor vehicle, double pistons perform a reciprocating movement in a cylinder. This movement is transmitted to the shaft, the double pistons in the cylinders each respectively forming decreasing cylinder chambers on one side and enlarging cylinder chambers on the other. Air is injected into the cylinder chamber with the greatest volume located on one side of the double piston and this air then compressed and consequently heated by the decreasing cylinder chamber. Water vapour is admitted to this heated air, which leads to an explosive pressure increase in the cylinder chamber and this increase drives the piston, the cylinder chamber situated on the other side of this enlarging cylinder chamber decreasing, once it has been filled with fresh air.

Title: DC/DC voltage converter having a resonant circuit
Inventor: REUSTLE HANS DIPL ING
IPC: H02M3/335
Filed: 1986-05-23
Abstract: In the case of a DC/DC voltage converter, the energy-storage inductor (Dr, Drz) is supplemented by a capacitor (C1) to form a resonant circuit. The switching transistor (Ts1) of the DC/DC voltage converter is switched on as soon as the voltage on the switching transistor (Ts1) has reached the value zero or a current starts to flow through a diode (D1) which bridges the switching transistor (Ts1) in the reverse direction. The magnitude of the output voltage (UA) is used as the criterion for switching the switching transistor (Ts1) off (Figure 1). <IMAGE>
Patent DE-3617965-A1 (DE)
Title: Extraction cupboard (fume cupboard)
Inventor: AAKJAER JOERGEN
IPC: B08B15/02
Filed: 1986-05-28
Abstract: In work cupboards with a glass front side arranged above an access gap to the work table of the cupboard, problems due to restricted view into the cupboard may occur as a result of the light reflections often present at the glass front side. In the cupboard according to the invention, this is avoided in that not only is the glass front side (20) arranged in a highly oblique manner, there being fewer possibilities for disadvantageous reflections, it can also be infinitely variably tilted, as a result of which the person working at the cupboard generally has the possibility of choosing a "reflection-free" oblique position. The cupboard is configured such that the glass front side (20) is [lacuna] by raising and lowering a vertical front-side part (10) without the free access area and suction area between the work table (6) and the lower edge of the glass front side (20) being changed, the extraction by the cupboard remaining operationally effective with a specific, acceptable suction capacity. <IMAGE>

Patent DE-3703124-A1 (DE)
Inventor: STREICHER MANFRED
IPC: F04B43/12
Filed: 1987-02-03
Abstract: A preferred peristaltic pump differs from known peristaltic pumps in that its inner space is completely filled with a liquid (34). In that case, a slack hose (24) can be instead of a hard elastic, self-erecting hose, thus enabling a high number of revolutions and a consequent high output to be obtained with small dimensions. The suction height is automatically adjusted to the suction height required at that moment. The pump is able to extract even at a low number of revolutions, as long as there is no black-flow due to the squeeze-point on the hose. The hose that can be used in this case can be considerably better squeezed than a hard elastic, self-resorting hose.

Title: Method and apparatus for determining the weight of a liquid in a container
Inventor: GIESECKE PETER DR
IPC: G01G17/04
Filed: 1987-05-23
Abstract: A method for determining the weight of a liquid in a container, especially in a tanker vehicle, in which the pressure of the liquid column is measured by a differential-pressure sensor, is to work in a simple way and be capable of universal use. This is achieved in that the differential pressure is measured by a diaphragm element or concertina element of high accuracy, in that the internal geometry and specific gravity of the liquid and the inclination of the container are determined and stored, and in that the weight of the liquid is determined from the pressure of the liquid column, taking into account the specific gravity of the liquid, the internal geometry and, if appropriate, the inclination of the container. As a result of the invention, a highly accurate determination of the weight or mass of liquids in containers of differing design, especially also in tanker vehicles, becomes possible by relatively simple means, with a plurality of influencing variables being taken into account. <IMAGE>
