Abstract: In order to facilitate the handling of a wet-dry vacuum cleaner, a carriage-type running gear 1 is used which is provided at one end with a structure 7, on which a lid 11 is hinged. Apart from the structure, the carriage has a standing surface 6 for receiving a container 6 which, when the lid is swivelled, is both mechanically fixed and also closed in a sealed manner. The motor/fan assembly 9 is arranged in the structure and connected to the lid in such a way that, when the lid is swivelled up, the suction line 10, 12 is interrupted. In order to replace a container of the vacuum cleaner, which has excellent handling characteristics due to the low position of the centre of gravity, the lid only needs to be swivelled up in order to be able to grip the container. <IMAGE>

Abstract: A phase lock loop circuit (50) for removing abrupt changes in a received signal (33), such as those caused when an object tracking system's directional receiving antenna (10) becomes misaligned with the tracked object, uses a phase detector (60) to determine when an abrupt phase change has occurred, such as when a signal returned from the tracked object aligns with an antenna null and would reverse the phase of a control signal (37) fed to a phase locked oscillator (56). The received phase signal (37) is compared with a reference phase (57a) from the oscillator (56) and the difference signal (63) used to trigger a Schmidt trigger (66) that controls a phase-reversing circuit (70) interposed between the loop mixer (52) and the oscillator (56). A delaying low pass filter (54) ensures the control signal (77) is stable before it is fed to the phase locked oscillator (56).

Abstract: In the rotary filter press, a rotor 4 having fins 5 is provided and the leading edges 13 of the fins 5 brush over a leading edge surface, in which a stator 6 supports a filter medium 7, which with a leading surface 12 lies opposite the leading edge surface 13 at a distance, and in which a substance between filter medium 7 and rotor 4 forms a closed circular flow pattern, and the filter medium 7 is maintained free from sediment. It is required that the freedom from sedimentation is maintained over an extended period of time. This is achieved by changing the distance between the leading surface 12 of the filter medium 7 and the leading edge surface 13 of the rotor 4 in a radial direction so that eddies 11 are formed in the circular flow pattern. Changing the distance increases the time period during which the filter medium is free from sediment and increases the filling level possible in the chamber for material to be filtered. <IMAGE>

Abstract: An antenna system (20) includes an array (22) of micro-­strip antenna elements (24) wherein each of the elements (24) includes two or more radiators (50). Electromagnetic signals are coupled from an input terminal (32) of each element (24) via one or more circulators (52) which allow for application of an input signal to a first of the radiators (50) followed by rerouting of respective signals to the next radiator (50). The radiators (50) are tuned to radiate at successively higher portions of the electromagnetic spectrum. By virtue of reflec­tions of higher frequency radiation from a radiator (50) tuned to a lower portion of the signal spectrum, each radiator (50) radiates only said portion of the signal spectrum falling within the bandwidth of the radiator (50). By using three radiators (50), each antenna element (24) is capable of radiating a signal spectrum three times as wide as are the bandwidths of a single radiator (50). Included within the antenna system (20) is one or more power dividers (36) to form one or more beams of radiation. With the use of plural power dividers, switching circuitry may be employed to select sequentially individual ones of the power dividers so as to scan a beam of radiation.
