Patent DE-3423941-A1 (DE)
Title: Releasable connection between the drive shaft and the receiving cone of a laboratory centrifuge
Inventor: MUELLER DIETER
IPC: F16D1/08
Filed: 1984-06-29
Abstract: A laboratory centrifuge is provided at the upper end of its drive shaft (1) with a head piece (2) which contains a gap-shaped opening (3). A frustoconical receiving cone (6), which can be placed on the head piece (2), contains tapped bores (7,8) in the radial direction into which threaded pins (9,10) can be introduced. The threaded pins (9,10), provided with a conical tip, engage in conically widened openings (4,5) in the region of the gap-shaped opening (3) when screwed tight, and accordingly form, besides a frictional connection, when screwed tight, an additional positive connection; the positive connection remains ensured even after a possible loosening of the threaded pins (9,10), since a centrifuge rotor which can be placed on the receiving cone (6) prevents the threaded pins (9,10) from leaving the receiving cone (6). A relative movement between the head piece (2) of the drive shaft (1) and the receiving cone (6) is prevented in this fashion. <IMAGE>

Patent DE-3500711-A1 (DE)
Title: Current-regulating circuit having a bridge circuit
Inventor: FIEBIG ARMIN ING GRAD
IPC: H02P7/03
Filed: 1985-01-11
Abstract: In the case of current-regulating circuits having semiconductor power switches in a bridge circuit, in which circuits the magnitude and direction of a DC current is regulated by a control voltage, using pulse-duration modulation, there is frequently an interfering dead region for small positive and negative DC currents when the control voltage passes through zero, in which dead region no change in the DC current in accordance with the control voltage takes place. This dead region can be compensated for by changing the triangular reference voltage which is required for pulse-duration modulation. The change takes place in a zero region in which the reference voltage corresponds to a datum voltage. When it corresponds to this datum voltage, the reference voltage is always briefly kept constant so that there is always a small time duration with a constant voltage between each triangular amplitude. This time duration normally corresponds to the safety time period of a safety arrangement which prevents the individual half bridges turning on incorrectly.

Patent DE-3512089-A1 (DE)
Title: Circumferential insulation for round pipes, in particular for chimneys
Inventor: BIHY LOTHAR
IPC: F16L59/02
Filed: 1985-04-02
Abstract: In the case of a prefabricated circumferential insulation for round pipes, such as inner chimney pipes, an insulating sleeve comprising two insulating panels (1, 2), which are planar in the storage and transportation position and, on the contrary, arched in the mounted position, is achieved in that the planar insulating panels (1, 2) are arched by lateral force on their planar end surfaces (7, 8), with the effect of spreading apart their expansion joints (9), and are mounted in this way. The two insulating panels (1, 2) are connected to each other by articulation strips (11) engaging over the expansion-joint edges (10), with the result that the end surfaces (7, 8) can move from an essentially aligned state, in the storage and transportation position, into a parallel state, in the mounted position. By means of corresponding projections in the region of the outer edges (14, 15) on the end surfaces (7, 8), it can be ensured that the joint (12), formed by the parallel end surfaces (7, 8) in the arched mounted position, is closed in a snugly fitting manner in each case. On transition between the storage and transportation state, on the one hand, and the mounted state, on the other hand, no excessive compressions of material, which would necessitate the use of material with particularly good spring-back properties, occur. The closure of the joint (12) in the mounted position can be additionally secured by self-adhesive tapes applied on the end side. <IMAGE>

Title: Environmentally friendly water heating or heating by means of air pressure (gas pressure)
Inventor: BROSS RAINER HENNING
IPC: F24H1/00
Filed: 1986-01-18
Abstract: Very environmentally friendly heating by means of compressed air. Absolutely no waste gases, absolutely no harmful substances. The pressure cylinder compresses the air (gas) by means of weight, as a result of which once the installation has been purchased no more electricity, coal, wood, gas or oil are required, that is to say full water heating absolutely free, completely independent of any weather and anywhere in the world. Even the "pumping-over" into a storage boiler can, if necessary, be carried out without great energy consumption simply by means of falling and with rising heating. By removing the heated domestic water (see schematic diagram), the pressure is reduced - new air being sucked in - and the compression process can start heating the water again from the beginning. In the case of a plurality of bundled cylinders operating at different times, it is thus possible to obtain hot water round the clock, independently of all external influences.
