Title: Method and device for switching over a three-phase drive
IPC: H02P25/20
Filed: 1988-09-22
Granted: 1990-02-01
Abstract: In the case of operating a three-phase asynchronous motor in the oversynchronous rotational speed range, the motor exerts a braking torque. If the three-phase asynchronous motor has two speed stages, this braking torque produced on switching over from the higher rotational speed to the lower rotational speed can cause a "switching shock" which can be dangerous. The switching shock is reduced if one phase winding of the stator winding is separated from the mains. Switching back of the phase winding is carried out in dependence on the voltage between the phase winding switched off and its phase, which voltage is lower in the case of synchronous rotational speed than in the case of neighbouring rotational speeds. The method is used in the case of pole-switching (pole-changing) motors or separate high-speed and micro-sped motors which are, for example, components of hoisting machines. <IMAGE>

Title: Apparatus and process for the continuous biological purification of waste water - in particular for relatively small and medium-scale businesses
Inventor: KUNZ PETER PROF DR
IPC: C02F3/10
Filed: 1993-06-29
Granted: 1994-10-20
Abstract: In view of increasing environmental problems in medium-scale industries, despite in some cases waste water constituents which are difficult to degrade and despite extreme variations, biological purification methods have recently been offered. However, generally these are merely miniaturisations of known processes. Since fixed-bed reactors and activation reactors have different optimal operating ranges and the submerged fixed-bed activation systems are also not optimal, the object of the invention is to propose a process and an apparatus which combine together the known advantages of the two principles. The object underlying the invention in concrete terms is to provide an apparatus which makes waste water purification possible in the respective optimal operating ranges in the case of both small and large waste water influx. The object is achieved by some of the microorganisms being held in a cage on support materials and this cage being able to be used both as a free-standing trickle-film reaction space and also in submerged form - supplied with compressed air - and some of the microorganisms, after separation of the sludge/water mixture, being detained in a conical vessel situated beneath the cage and used as submerged microorganisms in the free pore spaces after impounding the cage in percolating filter operation.

Abstract: A pressure-compensated solenoid valve for controlling the passage of a connecting line 18 between a high-pressure side connected to a fuel injection nozzle and a low-pressure side, with a multi-component valve housing 2 which has a line section 19 of a high-pressure-side inflow line and has a step-shaped guide hole 3 in which a step-shaped control slide 5 which has a flat armature 7 can be displaced as a valve closing element by an electromagnet 6 counter to the force of a restoring spring 8. There is a transverse hole 11 in the control slide 5 whose slide components 5a, 5b, which have diameters of different sizes, are guided in correspondingly matched stepped hole parts of the guide hole 3. The end side 14 of the larger slide component 5b which contains the axial hole 10 forms, together with the planar bearing face 12 of a housing component into which a high-pressure-side line section 20 extends coaxially to the axial hole 10, a flat valve seat. Pressure shoulders 3c, 5c, are formed by junctions between the two slide components 5a, 5b and stepped hole parts 3a, 3b and bound an annular space 9 into which the tranverse hole 11 opens. The opening cross-section F1 of the line section 19 corresponds to the annular cross-section F2 formed by the pressure-shoulder 5c. <IMAGE>

Title: Method and apparatus for the production of a monolithic refractory lining for steel casting ladles
Inventor: STRIPP HEINZ WERNER DIPL ING
IPC: B22D41/02
Filed: 1994-02-03
Granted: 1995-05-04
Abstract: When the wall and bottom of a steel casting and handling ladle are provided at the same time with a refractory monolithic lining, the lining in the lower area of the wall is often damaged during intermediate repairs of the bottom. According to a new process, wall and bottom are lined one after the other. A hose-like inflatable sealing body is secured to the bottom part of the template (4) when beginning to introduce the casting mass in the wall area and is inflated so that it seals the template (4) up to the height that corresponds to the desired thickness of the bottom. As soon as the casting mass in the lower wall area is sufficiently set, the sealing body (2) is deflated and removed, then the refractory casting mass is introduced into the bottom area up to the desired height. This process is suitable for steel casting and handling ladles and for similar metallurgical vessels.

Title: Pressure meter such as barometer, sphygmomanometer for measuring arterial blood pressure, or manometer which uses fluid columns, giving reliable and accurate presentation of pressure to be measured
Inventor: VISSER FRITS JAN
IPC: G01W1/00
Filed: 2004-01-26
Granted: 2005-07-27
Abstract: The pressure meter such as a barometer, sphygmomanometer for measuring arterial blood pressure, or manometer which uses fluid columns, giving reliable and accurate presentation of pressure to be measured. Mercury is not used and there is automatic correction for variations in the ambient temperature. Provision is made for verification of the level on which the meter is used. The meter is related to the tendency barometer and is a fluid barometer, with gas-filled (9) closed tube arm (8) and a reservoir (10). Since measurement is on the closed tube arm, the first difficult negative scale variation is discarded. The correction for the altered pressure of the gas in the closed arm on variation of the ambient temperature is obtained by using the expansion coefficient and the similar weight of the barometer fluid (5). As the temperature in the ambiance rises, the gas in the closed tube end will expand and a quantity of fluid (5) will be impelled to the other tube arm (3), until the height difference in the fluid levels in both tube arms further exactly compensates the gas pressure. The level in the closed arm will now be lower, and that in the open arm higher.
