Patent EP-0345690-A1 (EP)
Inventor: KOTHMANN ANTONIUS BERNHARD
IPC: E02B11/00
Filed: 1989-06-05
Abstract: An apertured pipe segment is disclosed which is of injection moulded plastics construction and can be used to form a well screen or sub-soil drainage pipe. Each aperture comprises a longitudinally extending inner slot 18 which extends from a slot mouth 24 inwardly and is defined by inwardly diverging slot walls 22, and an outer slot 20 which extends from the outside of the pipe segment inwardly to the slot mouth. The smallest width of the outer slot is greater than the width of the slot mouth. The inner slot is open longitudinally to one end of the pipe segment and the outer slot is open longitudinally to the other end of the pipe segment. The pipe segments can thus be made by an inexpensive two-part mould not requiring collapsible cores.

Abstract: The invention relates to a current amplifier comprising an input terminal (1) for receiving an input current, an output terminal (2) for supplying an output current, a first transistor (T₁) having a base-emitter junction coupled to the input terminal, and a second transistor (T₂) having a collector coupled to the output terminal and having an emitter arranged in series with a voltage source (4), the series arrangement of the voltage source and the base-emitter junction of the second transistor being arranged in parallel with the base-­emitter junction of the first transistor, the first transistor being of the NPN conductivity type and the second transistor being of the PNP conductivity type. The low internal series resistor of the NPN transistor T₁ allows a comparatively large input current I in , so that the attenuated output current (I out ) is a linear function of the input current over a wide range. This results in a current-sourcing attenuating current mirror having a far better linearity than a current amplifier in which the first and the second transistor are both of the PNP conductivity type.

Abstract: By providing a patient table with round edges a coupling between a trolley and the patient table can be simply realised for the transfer of a table top from the trolley to the patient table. When the patient table is lifted, the table top is decoupled from the trolley after which the trolley can be decoupled from the patient table so as to be removed. The lifting construction of the patient table enables a large stroke to be made in a vertical direction without giving rise to longitudinal displacement of the table top. The patient table comprises a hydraulic displacement mechanism for a longitudinal displacement of the table top; this mechanism can also be operated by hand in the case of emergencies.

Abstract: The present invention relates essentially to a process for the manufacture of a composite material possessing a metallic matrix. This compound consists of a reinforcement based on alumina or alumina-silica ceramic fibres forming a felt whose cohesion is provided by a silica binder, this reinforcement being impregnated under high pressure with an aluminium-silicon alloy, in the liquid state, containing magnesium, the said alloy having a magnesium content chosen in particular as a function of the initial silica content of the reinforcement, so as to achieve a total reduction of the silica without formation of a residual magnesium-silicon compound at the matrix-reinforcement interface. The composite materials obtained by this process can be used in the automotive industry, for example to manufacture the components of a motive power unit.
