Plug for two-conductor cord or multi-conductor cord produced of semi-hard plastic material, and consisting of two identical halves, into which two electrical conductive prongs (1) are placed, at the rear part of which knives (2) are placed for penetrating the isolating material of the cord for electrical connection, and that the two identical halves are locked together by dowels (5) without the us...

1. Connector apparatus being arranged in an alarm divice socket (1) between an alarm device and a central signal station, the connector being provided for a plurality of alarm devices of different types which are provided for detecting predetermined changes of state in the environement under different environmental conditions or for predetermined applications, characterized in that in the alarm de...

A hip implant has a stem portion with a substantially linear axis and a circular cross-section at least in the region of the bottom end thereof. A wedge-shaped portion extends medially from the stem at or near the top end of the stem. The wedge-shaped portion is surmounted by a ball.

The cell cultures are obtained from the kidneys of pig carcasses by digestion with a proteinase. Cell cultures of this type can be used advantageously for growing viruses.

The device is intended for Jacuzzi's containing among other things a first pump (8) designed to pump water from the pool (1), through a filter device (20) and back to the pool (1) and a second pump (15) designed to pump water through for therapy and/or massage intended nozzles (19). The compression face (7) for the first pump (8) and the compression face (16) for the second pump (15) are both conn...

The first and second parts (5,6) of the device are constructed from thin material. The second part has a recess (7) defined by an edge deviating from a circle line. The edge is irregularly formed, and provides accordingly thin edge parts (9-13) suited for using used material attached to a tool or instrument.

A single phase winding system comprises basic windings (U1-U2 symmetrically V1-V2) distributed over the 3) tracks of a stator, and in the same winding operation additional windings (U2-U3/V2-V3) are produced. Since the two windings (I,II) are wound continuously without interruption, there are no extra connecting points. The windings system may be coupled so that a four-pole distribution system is ...
