Abstract: PCT No. PCT/DE88/00651 Sec. 371 Date Jun. 19, 1990 Sec. 102(e) Date Jun. 19, 1990 PCT Filed Oct. 24, 1988 PCT Pub. No. WO89/06048 PCT Pub. Date Jun. 29, 1989.The risk of a latch-up is diminished by the incorporation of an additional bypass transistor between the output (OUT) and the supply voltage (VDD) of an integrated circuit, for example a CMOS output stage. In case positive over-voltages that are greater than the sum of the supply voltage (VDD) and the conducting-state voltage of the bypass transistor occur at the output (OUT), the bypass transistor becomes conductive and represents a low-impedance connection between the output (OUT) and the supply voltage (VDD). In this case, the bypass transistor (BT) suctions additional charge carriers off and thereby increases the trigger current needed for the appearance of latch-up. The incorporation of an additional bypases transistor is possible both given well-shaped semiconductor zones that lie at a fixed potential as well as given well-shaped semiconductor zones that are wired to a variable potential.

Abstract: In such a device, there are difficulties when the axes of sleeve (7) and steam generator pipe (3) do not align. There are also problems with positioning the sleeve (7) exactly in its end position. To bring about accurate centring and positioning of the sleeve (7), it is envisaged that a lead-in (39) is formed by a connecting sleeve (40) which is supported resiliently in the axial direction. The sleeve (7) is clamped between a shoulder (18) of a holding grip (16) and a centring piece (17) which is variable in its external diameter. In this connection, the greatest diameter of the shoulder surface is smaller than the internal diameter of the connecting sleeve (40). The holding grip (16) is assigned a further shoulder (48), the axial distance of which from the first shoulder (18) is further away from the pipe bottom (1) than the first shoulder (18), by the height dimension of the connecting sleeve (40). The shoulder surface of the shoulder (48) comes to bear against an end surface of the connecting sleeve (40) which faces away from the pipe bottom (1), while an end surface of the connecting sleeve (40) which faces towards the pipe bottom (1) makes contact with it. …<IMAGE>…

Abstract: A process for manufacturing a high bulk density particulate detergent composition, of a bulk density greater than 0.7 g/cc and preferably in the range of 0.8 to 1.0 g/cc, includes turbodrying a mixture of synthetic anionic organic detergent, preferably of sodium C₁₂₋₁₃ linear alkylbenzene sulphonate, water, and fabric softening bentonite, in which turbodrying process the mixture is repeatedly subjected to centri­fugal and axial forces which create thin films of the mixture, which are pulled apart, due to such forces, to form particles, which are further turbodried and thereby converted to high bulk density particles of substantially globular shape and desired particle sizes. In a preferred embodiment of the invention the mixture charged to the turbodryer is made by turbo­mixing an aqueous solution, dispersion or paste of anionic detergent with bentonite, and the mixture made thereby is directly turbodried. 
     Also described are combined turbomixing and turbo­drying apparatuses, and products of the invented processes.
