Title: Centrifugal force and filtration of eccentric filter fabric - separates dust from contaminated gas
Inventor: SEKTA HENRYK
IPC: B01D50/00
Filed: 1991-01-16
Abstract: A cyclone-type unit for removing dust from a gas stream injects the gas tangentially (4) into th gap beween a cylindrical wall (1) and a suspended drum-like basket (2) covered by filter fabric. An overhead drive rotates the basket at a speed generally euqal to the incoming gas stream.

USE/ADVANTAGE - The connectors have metal screen around the connector elements which prevents cross-coupling of electrical signals between the elements. Insulation of the elements from this screen, which can be solid metal or a obtd. metallisation film on a plastic housing, is by coating the elements with an insulating film in discrete areas, i.e. those areas which do not have to be available for electrical interconnection. This requires in inexpensive modification of the mfr. process and allows most of the existing tooling to be used. The compsn. of the coating can be adapted to requirements for high or low dielectric constant.

Title: Assembly for changing lead battery with nickel cadmium battery charger
IPC: H01M50/296
Filed: 1991-12-11
Abstract: The lead battery assembly includes a voltage detecting circuit used to detect the voltage of a lead battery and an automatic voltage charging circuit. The circuits are connected to the lead battery and contained together with the lead battery in a housing. A connecting base is electrically engaged with the circuits, and the connecting base is adapted to engage with a cahrger for a nickel cadmium battery.The detecting circuit detects that the voltage of the lead battery reaches a certain value, and sends a signal to the voltage changing circuit to slowly lower the voltage.

Filed: 1992-03-07
Abstract: In order to accelerate an asynchronous machine (5), its stator is connected via a switch (S2) to a secondary winding (W3) of a converter transformer (T1), while the rotor is connected via a cycloconverter (3, 4), in a V-circuit, to secondary windings (W2, W3) of the converter transformer (T1). The secondary winding (W3) has a reduced AC voltage (U12) on the converter side, in the region of 5% - 10% of the AC voltage (U1) of the AC power supply (1). The asynchronous machine (5) is coupled on the rotor side to a single-phase synchronous machine (6). Such rotating frequency converters are used for transmitting electrical power in the range from 8MW - 90MW from a national grid (1) at 50 Hz or 60 Hz to a single-phase railway network (2) at 16<2>/3 Hz or 25 Hz, and vice versa. The single-phase synchronous machine (6) is not energised during acceleration, so that undesirable harmonic torques at double the stator frequency do not occur and a longer life of mechanical components, such as pole connections, fans etc., is achieved. <IMAGE>
