Abstract: The invention relates to a mechanism for an earth fault current circuit breaker combined with a line circuit breaker. In this case, the intention is to design an earth fault current circuit breaker which can be combined with one or more already known line circuit breakers. In contrast to the known earth fault current circuit breakers, it is intended to use only a small number of structurally uncomplicated components. The solution consists of a rotationally moving trip plate 6 which is effectively connected to an operating member 5 of the trip device 4, a return plate 15, which is subject to the pressure of a spring 20, and a trip lever 13 for the earth fault current circuit breaker, the return plate being connected in a hinged manner via a return clip 21 to a transmission member which is constructed as a switch-off clip 25 for the line circuit breaker. The single latching point in the earth fault current circuit breaker consists of the trip lever 13 which operates in conjunction with a latching lever 27. During tripping, the spring 20 fulfils a double function, namely returning the trip device 4 and switching off the line circuit breaker. <IMAGE>

Abstract: This color-copying system scans a colored original with a raster input scanner to generate digital signals representing red, green and blue, and prints at a raster output scanner which uses cyan, magenta, yellow and black ink. In addition, under-color removal is used, being defined as the removal of a certain amount of ink from all three colors, and the addition of an equivalent amount of black ink. The first step is to convert the input scanner colors into the color being printed during the current revolution of the printing drum. This requires the solution of three equations, each of which uses three look-up RAM tables (28, 37, 44). In addition, the amount of under color removal must also be calculated before the amount of ink for the dot being printed is known. This requires an additional table look-up (73). Finally, for the black cycle, the amount of black ink must be calculated, requiring another table (82). The resultant circuit, therefore, consists of nine RAM tables for the color equations, each of which is reloaded with new values at the beginning of each color-printing cycle, two black tables, and the associated circuitry to perform the associated computations and to establish the synchronization and timing to allow the system to operate at reasonable speeds.

Abstract: A magnetic field enhanced single wafer plasma etch reactor (60) is disclosed. The features of the reactor include an electrically-controlled stepped magnetic field for providing high rate uniform etching at high pressures; temperature controlled reactor surfaces including heated anode surfaces (walls and gas manifold) and a cooled wafer supporting pedestal/cathode (70,72); and a unitary wafer exchange mechanism (74) comprising wafer lift pins (79) which extend through the pedestal and a wafer clamp ring (78). The lift pins and clamp ring are moved vertically by a one-axis lift mechanism (140) to accept the wafer from a co-operating external robot blade (76), clamp the wafer to the pedestal and return the wafer to the blade. The electrode cooling combines water cooling for the body of the electrode (70) and a thermal conductivity-enhancing gas interface between the wafer and electrode for keeping the wafer surface cooled despite the high power densities applied to the electrode. A gas feed-through device (114, 175, 176) applies the cooling gas to the RF powered electrode (72) without breakdown of the gas. Protective coatings/layers (81,83) of materials such as quartz are provided for surfaces such as the clamp ring and gas manifold. The combination of these features provides a wide pressure regime, high etch rate, high throughput single wafer etcher wich provides uniformity, directionality and selectivity at high gas pressure, operates cleanly and incorporates in-situ self-cleaning capability.

Abstract: A method of splitting a soluble oil effluent, in which the effluent is applied to a coarse separator and then mixed in successive stages with a polyelectrolyte and a coagulant, the resultant flocculated oil/water phase then being treated in a dissolved air flotation unit whereby to separate and recover the oil and water fractions. A coagulating tank may be provided immediately downstream of the mixer stages for the mixture to dwell for a period and a clarifier tank may follow the coagulating tank, again to provide a dwell period for the separating mixture, the floating oil being recovered so as to provide a cleaner/clearer mixture for the dissolved air flotation unit. 
     Oil concentrations of 0.1% to 25% in the effluent may readily be treated from which substantially oil free water (oil level of the order of 0.01%) may be obtained. With further processing, "polishing," this may be reduced again eg to 0.003%. Further, the chemical oxygen demand on the water course with this much cleansed effluent is reduced by a significant factor (about 8) compared with practice hitherto.

Abstract: To produce a mat from continuous filaments or staple fibres or the like, a laid structure formed from these particulate materials is subjected to the action of fluid jets which are directed perpendicularly against the plane of the laid structure and which impinge upon the laid structure in a uniform manner in rows of dots. As the laid structure moves by, the fluid jets are pivoted in such a way that no relative motion results between their points of impingement and the laid structure. This process is carried out using two driven rolls (11, 15), of which at least one is rotatably mounted on a hollow axle (10) and equipped with radial holes (14a, 14b) which are arranged over the circumference in uniform distribution. The rolls (11, 15) are provided with profiles (18 and 16 respectively) via which they engage with one another to form, in the engagement zone, chambers (19) within which the holes (14a and 14b) end and intensively fluidise the particulate materials contained therein. <IMAGE>
