Title: Improved method of artificially heating sludge digestion chambers
IPC: C02F3/28
Filed: 1927-12-08
Abstract: 297,250. Pr³ss, M. Dec. 8, 1927. Bacteriological processes; plant.-To maintain the temperature in a sludge digestion chamber at about 25‹ C, the fresh sludge, prior to its introduction into the chamber, is heated to above this temperature. A suitable apparatus comprises a digestion chamber a surmounted by a chamber h in which sludge is heated by coils i. When sufficiently heated, it is allowed to flow into the digestion chamber through valved pipes m. The whole contents of this chamber are then well mixed together by an agitator n to equalize the temperature throughout the chamber. The upper part of the apparatus may be formed with cavity walls to minimize loss of heat, and the lower part may be protected by situating the settling basin b on the other side of its wall, the fresh sludge then being raised by pipes f to the chamber h. In addition, digestion chamber water may be drawn from the chamber a and heated in the chamber h between the regular introductions of fresh sludge. If the fresh sludge is rich in water, it may be subjected to a primary, at least natural digestion, heating before introduction into the chamber h. If the sludge is poor in water, it may be first mixed with warm digestion chamber water.

A negative resistance circuit arrangement comprises a device having two bodies of different energy gaps separated by a dielectric layer thin enough to allow tunnelling at least one of the bodies being a super-conductor or semi-conductor which is subjected to the influence of temperature near 0 absolute, or magnetic field or radiation to vary the width of its energy gap. Fig. 1 shows an element consisting of bodies 11 and 13 of super-conducting or semi-conducting material having different energy gaps and separated by an insulating layer 12, which is thin enough to permit tunnelling. The bodies may consist of a wire or 0À001 mm. film of super-conducting materials such as Al, Pb, Sn, Ta, Nb or In, or of semi-conducting materials such as Ge, BiTe, PbTe, SiC, GaAs, Mg 2 Sn, InSb, Cs 3 Sb, CdS, SnO doped if desired with As, Sn, P or In. The insulating layer may consist of a layer 10-20  thick of aluminium oxide, silicon monoxide or cuprous oxide. Fig. 4 shows the voltage current characteristic of the element which is symmetrical about the origin and has negative resistance portions. The nature of the characteristic may be controlled by varying the temperature or strength of an applied magnetic field to modify the transition temperature and energy gap of the super-conducting materials or by applying radiation to modify the semi-conductor material. Fig. 9 shows apparatus for this purpose in which an element 32 such as shown in Fig. 1 is suspended in liquid helium 22 in a Dewar flask. Coil 38 provides a controllable magnetic field around element 32, the temperature of which may be modified by heater 36. Lamp 40 provides a means of subjecting element 32 to further control by submitting it to radiation. Control may also be effected by passing current through one of the bodies or by introducing an additional member into the element to provide means for providing a variable magnetic field. The element may be mounted in a waveguide or cavity of super-conductor material. One body may be associated with two insulating layers, each bearing another body, so providing two elements.
