Title: Drainage interceptor tank
IPC: E03F5/16
Filed: 1980-09-17
Abstract: An interceptor tank (6), designed to prevent liquid of low specific gravity such as oil or petrol at garages from being discharged with surface water into the sewage system, is divided into three superposed separation chambers (8, 10, 12) by partitions (14, 16). Water containing petrol or oil is delivered through to the inlet (42) to the lowermost chamber (8), the partitions being provided with apertures (26, 28) whereby water may pass upwardly from the lowermost to successively higher chambers, and through discharge outlet (38). A supplementary compartment (18) is so connected to the chambers that floating oil or petrol flows therefrom from the chambers into the compartment (18) whose outlet (48) is positioned at a level higher than the outlet (38) from the uppermost chamber. Liquid from the supplementary chamber (18) flows through the outlet (48) into a collection chamber (50) from which water may be removed from the lower part, and low s.g. liquid from the upper part. <IMAGE>

Title: Matrix addressing of opto-electric displays
IPC: G09G3/36
Filed: 1980-10-08
Abstract: Matrix addressing of opto-electric displays such as liquid crystal displays and electroluminescent displays of the kind comprising a first set of N conductors (Y1 to YN) and a second set of M conductors (X1 to XM) forming NxM intersections or elements whereby a particular information display is obtained by altering the optical property of the display at selected intersections by application of a predetermined cyclically repetitive set of N drive voltage waveforms, independent of the information to be displayed, to the first set of conductors, and a set of M drive voltage waveforms to the second set of conductors selected in dependence upon the information to be displayed, such that their interaction with the predetermined set of waveforms applied to the first set of conductors, integrated over the repetition period of the predetermined set of waveforms applied to the first set of conductors, integrated over the repetition period of the predetermined set, produces a visual display of the information. In accordance with the invention, the predetermined set of N drive-voltage waveforms, which is advantageously applied to the smaller conductor set having an odd number of conductors, comprises, at any instant, a substantially equal split between two voltage levels, which may conveniently be of equal magnitude but opposite polarity. The waveforms applied to the second set of conductors may simply comprise two-level waveforms, or, where selective weighting of the display brightness of display elements associated with respective conductors of the second set is required, e.g. to obtain uniformity of contrast over the whole display, three or more level waveforms may alternatively be used. The specification describes in detail the application of the invention to small alphanumeric displays as well as waveform or oscilloscope displays operating in either RMS or direct response modes.

Title: Artificial respiration apparatus
IPC: A61M16/00
Filed: 1980-11-06
Abstract: An apparatus for automatic and manual artificial respiration has an artificial respiration bellows (13) in a pressure chamber for automatic artificial respiration and a respiration bag (20) for manual artificial respiration. The apparatus operates either as a "half-closed" system or as a "half-open" system, the changeover from one system to the other being effected by switching a changeover valve (30). During automatic use when operating as a "half-closed" system, the respiratory gas, impelled by the bellows (13), passes through an inhalation branch (43) for inhalation into the lungs (18) and upon exhalation returns via an exhalation valve (22) and the changeover valve (30) to the respiration bellows (13). During manual use when operating as a "half-closed" system, the respiratory gas is passed by pressure on the respiration bag (20) via a bypass line (42) into the lungs (18) and upon exhalation returns via the changeover valve (30) to the respiration bag (20). During both manual and automatic use when operating as a "half-open" system, the respiratory gas flows along the same inhalation path, and, during exhalation, passes via the exhalation valve (22) and the changeover valve (30), now switched over, into a waste gas line (32). The apparatus is used e.g. for anaesthesia. <IMAGE>

Title: Transformer with a Releasably Connectible Magnetic Circuit
IPC: H01F27/26
Filed: 1981-11-25
Abstract: A large, e.g. oil-cooled, power transformer is assembled from at least two separately transportable units each comprising a magnetic circuit and associated transformer coils enclosed within a sealed tank. Parts of the magnetic circuit of each unit protrude from the associated tank via respective seals so that the protruding magnetic circuit parts of the two units can be releasably coupled together to provide a magnetic coupling between the two units. The invention has particular application to transformers which, due to their size and weight, would be impracticable to transport fully assembled. The self-contained transformer units of the invention can each be made of a conveniently transportable size for assembly at a user site into a larger multi-unit transformer while obviating the need to expose the working components of the transformer to the deleterious effects of draining and refilling the tanks with cooling oil as in existing systems. <IMAGE>
