Abstract: PCT No. PCT/EP93/03533 Sec. 371 Date Aug. 18, 1995 Sec. 102(e) Date Aug. 18, 1995 PCT Filed Dec. 14, 1993 PCT Pub. No. WO94/14882 PCT Pub. Date Jul. 7, 1994A method for treating sludge by dewatering to form thick sludge and drying to form dry sludge includes the steps of mechanically predewatering thick sludge to produce predewatered thick sludge and mixing the predewatered thick sludge with non-cooled dry sludge to produce a sludge mixture. The temperature of the sludge mixture to be dried is measured and the dry substance contents of the dry sludge based on the measured temperature is determined. Fluctuations in the dry substance contents of the dry sludge are compensated by controlling the amount of recirculated dry sludge to be mixed with the predewatered thick sludge as a function of the temperature of the sludge mixture to be dried. The sludge mixture is dried to produce dry sludge and a portion of the dry sludge is recirculated to be mixed with the predewatered thick sludge.

Title: Component with internal screw thread
Inventor: NOWAKOWSKI WALDEMAR DIPL ING
IPC: B62D27/06
Filed: 1993-03-26
Abstract: The invention relates to a component with internal screw thread (7), for example to a self-securing weld nut (1). For this purpose, an annular body (9) consisting of an elastic material is assigned to the internal screw thread (7) and inserted in a cutout (8) of the weld nut (1). According to the invention, the annular surface of the annular body (9) is sealed by means of an integrally formed diaphragm (10) which serves to protect the internal screw thread (7) against soiling and can be penetrated by a screw which is to be screwed in. Consequently, the annular body (9) not only has the task of the self-securing of a screw connection, but, moreover, also has the task of a sealing element on one side in order to protect the internal screw thread (7) against the penetration of dirt (Figure 1). <IMAGE>

Inventor: LOCH FRIEDHELM
IPC: D06F39/12
Filed: 1993-03-30
Abstract: For simplification of known column kits for the anti-tip security fixation of two superposed household machines 1 and 3, it is proposed that the kit contain four simple foot plates 6 in exchange for the standing feet, a device 7 to 10, 12 and 13 for securing the rear bottom edge of the machine 3 mounted on top against lifting off from the worktop 2 and an arrangement 11, 14 to 17 for securing the front bottom edge of the machine 3 mounted on top against movements in the direction of the front side of the machines. On the one hand, the housings of the superposed machines are thereby located so close one above the other that front and side panels for concealing the gap between the worktop 2 and the housing of the machine 3 mounted on top can thus be dispensed with, and on the other hand the kit is reduced to a minimum in terms of the parts required. The assembly of such a kit is thus simplified to such a degree that technically inexperienced people are able to carry out the assembly independently. <IMAGE>

Title: Brake control system for electric AC motor driven vehicle with DC battery - charged during regenerative braking and charge conditions detector determines battery charge conditions and gives signal if charge condition exceeds preset value
Inventor: SHOTARO NAITO
IPC: B60L11/18
Filed: 1993-09-17
Abstract: The drive motor is a 3-phase motor supplied by an inverter (2) fed by a DC battery. The charge condition detector (5) transmits a signal to a control part (3), if the charge condition of the battery (4) exceeds a predetermined level so that the charging current to the battery is reduced. It is possible with this reduced current, the power supplied to the AC motor is not sufficient to produce a required braking torque. In this event the control part (3) switches on an electrical load (9) to raise the braking torque. If a further load absorption is required, the control part switches on the electrical braking unit, which includes a switch (81) and a resistance (82). ADVANTAGE - Charging current to battery is controlled on basis of charge condition of battery, so that overcharge of battery is prevented.
Patent DE-4332044-A1 (DE)
Title: Furnace probe camera with technoscope
Inventor: HALLMANN KLAUS
IPC: C03B18/10
Filed: 1993-09-21
Abstract: A furnace probe camera which is particularly suitable for the production of float glass does not influence the production process of the glass and can be optimally arranged and entails a much lower coolant and nitrogent requirement since the camera, optics, filter and cabling are not arranged inside the hot area but, instead, on the outside. These parts of the monitoring unit are connected to the mirror arranged at the occular opening via a technoscope, that is to say an optical system of prisms and lenses, so that both repairs and adjustments are greatly facilitated. Above all, however, the diameter of the cooling probe can be substantially reduced which results in the advantages described. <IMAGE>
