Title: Equipment for cleaning water pipes etc. - delivers alternate water and air pulses from injector pump whose mixer tube is uncovered as float controlled water level drops in container
Inventor: OERTZEN JASPER VON
IPC: E03F9/00
Filed: 1991-07-31
Abstract: Cleaning is done by sending alternate clean water and air pulses along the pipe. A container (1) is connected to a water source (2) through a float-controlled shut-off valve (3,4) which sets the max. water level. Fitted inside the container is an injector pump (5, 7, 8, 9) whose mixer tube inlet (8) is below the max. water level and whose output (9) is connected to the pipe to be cleaned (15). The injector nozzle (7) of the injector pump is connected to a high pressure water pump (10) whose input in turn is connected to the water source (2). When the system is turned on water is driven through the pipe to be cleaned until the container water level falls below the level of the mixer tube inlet (8), when instead of water, air is drawn into the mixer tube and pumped through the pipe. As the container fills air is once more replaced by water and the cycle is repeated. ADVANTAGE - Simple, low-cost system. Avoids use of compressor and need for air to be purified of oil.
Patent DE-4126418-A1 (DE)
Inventor: HERTRAMPF MICHAEL DR
IPC: B65D41/04
Filed: 1991-08-09
Abstract: A screw cap for sealing a bottleneck or the like with a substantially cylindrical securing section (1) with a female thread (2) which can be screwed on a male thread (7) of a bottleneck (8). The base of the screw cap forms a sealing section (3). In addition, there is a stop to define the position at which an edge of the bottleneck bears on the securing section. This stop is on the inner wall of the cylindrical securing section and preferably forms a bearing surface (6) in a plane perpendicular to the screw axis. As the bearing surface is on the outside of the bottleneck, the face of the bottleneck is free for the abutment of the sealing section or a seal. The stop securely establishes a given screw-on distance even when the cap is detached and refitted several times with differing torques and thus ensures that the force with which the sealing section or seal bears on the face of the bottleneck is precisely defined. This also precisely defines the pressure which, when exceeded, results in an increased internal pressure escaping from the bottle.

Patent DE-4129832-A1 (DE)
Inventor: BECKER WILLI
IPC: F16H21/00
Filed: 1991-09-07
Abstract: The invention relates to a force amplifier with a lever mounted on a base and having a source of force and a clamping location. A force amplifier of this kind is to be designed in such a way that, while being of compact construction, it provides high amplification, does not exhibit any self-locking and amplifies the force in linear fashion. This is achieved by virtue of the fact that the source (3) of force acts with its supporting force on a lever arm (23) of a further, second lever (20), the other lever arm (22) of which feeds the reaction force back to the first lever (10%) supported on the base. The second lever (20) can be supported on the base (1) or is supported on a further lever which in turn feeds the reaction force back in the same way to the first lever. A lever system of this kind can be expanded as desired. <IMAGE>
