Title: Hydraulic dual circuit brake system
Inventor: LEIBER HEINZ DIPL ING
IPC: B60T8/44
Filed: 1987-07-18
Abstract: In a hydraulic dual circuit brake system for a vehicle equipped with an antilock system, the brake assembly comprises two master cylinders combined in a twin construction, which can be actuated by way of a moment-balanced rocker, on which the - boosted - actuating force acts, proportional to the pedal force. For this purpose, a drive cylinder of the brake booster is provided, which is designed as double-acting cylinder with working surfaces of different size. For booster operation, the smaller piston surface is acted upon by the outlet pressure of a brake valve, which delivers an outlet pressure proportional to the pedal force. For controlling pressure reduction phases of the antilock control, the piston surface defining the working chamber of the drive cylinder, otherwise relieved of pressure, is acted upon by the pressure of the servo pressure source, as a result of which the booster cylinder of the brake booster is driven with the effect of a pressure reduction shift of the master cylinder piston. Pressure-maintaining phases can be separately controlled by means of the brake pressure control valves on the wheels provided for the antilock control.

IPC: F04D29/60
Filed: 1987-08-26
Abstract: A device for lifting and lowering a submersible motor-driven pump. Starting from a lifting device with a load lifting member which can be moved up and down on a guide and is to be connected via a coupling device to a carrying part arranged on the submersible motor-driven pump, the object of the invention was to ensure the safe lowering and - above all - the safe lifting of such submersible motor-driven pumps which are arranged in a heavily contaminated pumping medium. To achieve the required safety, the solution according to the invention uses such elements which have proved reliable as load lifting members, such as load hooks and shackles. So that these elements can also be made suitable for coupling and uncoupling at a remote location which cannot be inspected, the invention provides for the load hook to be moved along two guide ropes, in the course of which the load hook acted upon by a counterweight in the direction of the unlatching position can be moved into the latching position by means of an actuating rope reaching to the upper level. <IMAGE>

Title: Microwave calorimeter
Inventor: STICKEL HARTMUT
IPC: G01R21/04
Filed: 1987-09-18
Abstract: The invention relates to a microwave calorimeter for the determination of the radio-frequency output power of a gyrotron in short-pulsed operation, the radio-frequency waves being transported in a circular waveguide, which is large in comparison to the wavelength, and absorbed in a medium, and the temperature increase of the medium being measured. The object of the invention is to configure the abovementioned microwave calorimeter in such a way, that a calorimeter for experimental short-pulsed operation of a gyrotron results which gives rapid indications and is therefore small in volume, avoids wave-type conversion in the circular waveguide and exhibits a low power reflection for all wave-types occurring. The solution is characterised in that a cylindrical absorbing container is provided, which has a container floor and lid, that the plane defined by the container floor is directed at right angles to the axis of the circular waveguide, and that the container lid is designed as a reflector.

Title: Process and apparatus for the energy enrichment of water, aqueous solutions or other liquids or melts
Inventor: HACHENEY WILFRIED DIPL ING
IPC: B01F27/91
Filed: 1987-11-11
Abstract: The process according to the invention and the apparatus developed for carrying out the process are intended to achieve the effect that liquids are enriched with suction energies in order to change the structural composition and characteristics. According to the invention, the liquid is introduced into a closed housing (10), which has an inner container (22) which at the top and bottom is in flow connection with the housing (10). Arranged in the lower region of the inner container (22) is an accelerator which rotates at high speed. By the suction effect, the liquid is moved in a laminar turbulent flow through the space between the housing (10) and the inner container (22). The centrifugal forces involved are relatively small or tend towards zero. The partial amount present in the inner container (22) is sucked off. Before the liquid flows into the inner container (22), a change in direction is performed, so that it flows in the opposite direction in spiral form through the inner container from top to bottom. This flow is maintained with continual changing of direction free from turbulence over a predetermined period of time. <IMAGE>

Patent DE-3804156-A1 (DE)
Title: Cover, in particular for manholes arranged in streets, roadways or the like
Inventor: MAUE HERMANN
IPC: E02D29/14
Filed: 1988-02-08
Abstract: A manhole cover consisting of a frame and a lid which can be inserted in the frame. The frame has an annular collar, the surface of which serves as a bearing surface for the lid due to machining. The lid in turn has a corresponding annular recess. A rubber ring is fastened in the recess so that the bearing plane between frame and lid lies in the bearing surface of the frame. The set-back recess of the lid is enclosed by a projecting, annular collar, the surface of which lies below the bearing plane formed by the bearing surface of the frame. Dirt particles fall into the annular gap between frame and lid into a collecting chamber formed by the base of the frame and by the annular collar of the lid. Since the bearing plane between the frame and the lid lies above this chamber, contact between the dirt particles located in the collecting chamber and the bearing plane is impossible so that no damage at all to the bearing plane can occur. <IMAGE>

Title: Avalanche victim search equipment
Inventor: STAUDINGER KONRAD
IPC: A63B29/02
Filed: 1988-03-01
Abstract: Field of application Sections at risk from avalanches are passed through by various persons, sometimes out of necessity, for example emergency services/ mountain rescue (rescue service), but also walkers and cross-country skiers. In such cases, people may on occasion be buried under snow, sometimes with a fatal outcome. Construction, function and operation A model aircraft motor is installed in a bright-coloured housing. The aircraft rises vertically for structural reasons. Weight and volume are kept low. The person to be protected is connected thereto by a red Perlon cord. In the section at risk from avalanches, the aircraft is set in operation and then flies at an appropriate height above the person (similarly to a balloon). No further equipment operation takes place. At the end of the section the aircraft is pulled in, switched off and packed as rapidly and easily as the launch. In the event of a burial, especially with released snow-boards, the aircraft remains on the surface and is easy to find because of the bright colour. Arriving rescuers require no technical aids (Pipser) and are directly connected to the victim via the red cord. Advantage Very rapid location of the victim. In the favourable case, manual uncovering of the respiratory organs. Minutes are often critical in death from suffocation.
