Title: Method for sealing disposal sites - involves drilling vertical holes through site, feeding explosive through then which on ignition produces hollow spaces beneath area
Inventor: PLAMBECK NORBERT
IPC: E02D31/00
Filed: 1990-07-18
Abstract: To obviate contamination of ground water and the environment, harmful disposal sites need to have a bed seal beneath the contaminated area (12), together with a lateral seal. A drilling machine (18) is used to form horizontally distributed vertical holes (14) through the site to be sealed, and ending at a distance beneath it. One part of the vertical holes (14,14') is less deep than the other parts (14'). The two types of hole are equal in number, with the deeper holes alternating with those less deep. At the lower end (20,20') of each type of hole an explosive charge (22) is positioned and ignited, which causes hollow chambers (24,24') to be formed. These chambers are then filled with a suitable sealant, e.g. bentonite. USE/ADVANTAGE - To protect ground water and the environment from contaminated disposal sites.

Patent DE-4030250-A1 (DE)
Inventor: WALLSTEIN DIETER DIPL ING
IPC: F28F19/00
Filed: 1990-09-25
Abstract: A heat exchanger for cooling hot crude gas containing aggressive components and for heating the pure gas obtained from the crude gas has a housing (1) formed by two lateral walls (2, 3) and upper and lower tubular bottoms (4, 5) . Partitions (8, 9) are linked to the lateral walls (2, 3) in order to form an inner cavity. In the upper and lower tubular bottoms (4, 5) are inserted the ends of a plurality of mutually parallel exchanger tubes (10) that extend parallel to the lateral walls. The hot crude gas flows through the exchanger tubes (10) and the pure gas flows through the housing (1) transversely to the exchanger tubes (10). The invention should ensure that the lateral walls of the heat exchangers are better protected against corrosion. For this purpose, an underpressure is applied to the cavities (6) formed between the lateral walls and the partitions, and the noxious gases of the pure gas that diffuse through the partitions into the cavities are fed by a duct into the stream of pure gas. Alternatively, an overpressure can be applied in the cavities formed between the lateral walls and the partitions.

Inventor: VOLZ PETER DR
IPC: B60T8/48
Filed: 1991-03-22
Abstract: A braking system with wheel-slip control, in particular for motor vehicles, comprising a master cylinder connected to the wheel brakes (VR, VL, HR, HL) via main pressure lines (2 - 2'''), consists of hydraulic auxiliary pressure pumps (15) and wheel sensors and electronic circuits for determining the wheel speed and for generating electrical braking pressure control signals which control the slip by controlling solenoid hydraulic inlet and outlet valves (1 - 1''' or 13) incorporated in the hydraulic lines. At least one volume-displacing pressure pulsation damper (3, 3', 3'', 3'''), which is connected alternately to the pressure columns of the two main pressure lines (2, 2', 2'', 2'''), is arranged between each of the wheel brakes (VR, VL, HL, HR) and the corresponding inlet valves (1, 1', 1'', 1''') of two main pressure lines (2, 2', 2'', 2'''). The sound energy generated in the liquid medium is converted to kinetic energy by the pressure pulsation damper (3, 3', 3'', 3''') and/or reflected at boundary surfaces of the pressure pulsation damper (3, 3', 3'', 3'''), independently of the valve switching frequencies. The noise due to switching of the valves is thus kept to a minimum without the pedal characteristic curve being adversely affected.
