Title: Activated sludge and clear water mixing - uses sample containers of dimensions to give exact ratios in a common mixing chamber
IPC: B01F15/04
Filed: 1991-12-07
Abstract: To achieve a precise ratio of matter in a mixture, esp. on dilution of activated sludge by clean water, between at least two samples, the sludge and water samples to be mixed are placed in containers (1, 3) with dimensions give the required mixing ratios as far as an overflow (18, 19). The container contents, up as far as the overflow, are transferred to a common mixing container (14). Sample containers (1, 3) of different dimensions can be used. The sludge volume is pref. determined in the mixing container, after the sludge has settled. At least two containers (1, 3) are fitted for samples of sludge and clear water, with the same dimensions as far as their overflows (18, 19) as the mixing ratios. The contents of each, as far as their overflows, are passed to a common mixing container (14). The contents of a container (1, 3) can be altered by moving the overflow (18, 19). A time-controlled pump (7,9) is in the feed to the each container (1, 3), and a control valve (12, 13) is in each transfer channel between the sample containers (1, 3) and the mixing container (14). USE/ADVANTAGE - The operation is used in refining sewage, to maintain a consistent sludge character and volume with periodic measurements. The samples of activated sludge and clear water are mixed with precise ratios to be determined how the sludge is diluted.

Title: Circuit for optically displaying faults in switch - displays fault if input voltage at switch input circuit exceeds predetermined threshold
Inventor: BOTT MARTIN DIPL ING
IPC: H01H9/16
Filed: 1992-02-20
Abstract: The circuit optically displays faults in a mechanical member (2) which is movable between two end positions, in each of which a register switch operates. The switches (8, 9) are each connected in series with identical input circuits (12, 17), to a power supply. The input circuits (12, 17) allow their input current to increase with increasing input voltage up to a set maximum value. If the voltage increases further, the current is lowered or held constant. The input circuits (12, 17) produce a binary output signal. The state of the signal varies in one direction when the input voltage exceeds a set limit and in the other direction when it falls below a set limit. The output signals control a switch parallel to a fault display (29-40). If the input voltage at one input circuit (12, 17) exceeds the set limit, the switch short circuits the display which is powered by a voltage supply. USE/ADVANTAGE - For monitoring e.g. isolating switches, power switches etc.  Suitable for a wide range of input voltages.

Title: Method for coating substrates with homogeneous uniform coatings - includes overlapping stream cones of plasma-activated gas and moving substrate carrier
Inventor: LYDTIN HANS-JUERGEN DR
IPC: C23C16/513
Filed: 1992-04-08
Abstract: Substrates (2) are coated by means of several PCVD sources (3a, 3b, 3c) arranged side by side in rows ((3) to (6)) following one another around the axis of rotation of a PCVD source carrier. Process gases are fed into separate plasma chambers, and plasma-activated gas streams (7a, 7b, 7c) are directed towards the substrates (2) mounted onto a carrier. The substrate carrier moves perpendicularly to the row direction of PCVD sources (3a, 3b, 3c). This motion takes place either in a straight line or about an axis of rotation which is parallel to the axis of rotation of the PCVD source carrier. Pref. the excitation power of plasma, the gas flow rate and/or pressure, and/or the distance of the substrates (2) from the outlets of the plasma chambers, and/or the shape of cross section of the outlets are chosen so that the stream cones (7a, 7b, 7c) overlap one another to produce a homogeneous uniform coating on the moving substrates. The rows of PCVD sources are arranged so that the stream cones emerging from the sources of adjacent rows do not overlap one another. The substrate carrier additionally performs a reciprocatory motion parallel to the row direction of PCVD sources. USE/ADVANTAGE - For coating substrates. It allows substrates with large surface areas to be provided with homogeneous uniform coatings.

Title: Process for the production of a large-volume nonwoven having surfaces consolidated on both sides
Inventor: PLOCH SIEGFRID DR
IPC: D04B21/14
Filed: 1993-03-30
Abstract: The invention relates to a process for the production of a large-volume nonwoven having surfaces consolidated at both sides, a relatively thin web being supplied at high speed, the fibres of the web being plaited by being deflected transversely to the web surface and transversely to the supply direction to form a bulky web, and the bulky web being successively delivered at lower speed to a first and a second stitching zone for the formation of stitches on one surface of the bulky web in each case. With the aim of making production more efficient and of increasing the transverse strength of the nonwoven, a web predominantly consisting of continuous elementary fibres with loop-forming reserves is used. The web supplied at the high speed is deposited on a conveying element, moved at the low speed, by means of a plaiter movable transversely and longitudinally relative to the web surface, the bulky web thereby being formed. The needles of the stitching zone are compound needles of a nonwoven-knitting machine and take up the elementary fibres in the surface region of the particular side of the bulky web to be consolidated. <IMAGE>
