Abstract: An apparatus and method for continuously removing liquid from an aqueous suspension; the apparatus consists of a filter housing; an electrofilter disposed within the housing to provide a crossflow chamber and filtrate chamber within the housing; means for supplying a suspension to the crossflow chamber and means for removing a suspension reduced in liquid content from the crossflow chamber, both means may be disposed so as to provide a crossflow of the suspension across the surface of the electrofilter or disposed to provide a batch process with optional stirring means; and outlet means for removing liquid from the filtrate chamber. A first electrode of the electrofilter is disposed on a surface of the crossflow chamber side of the electrofilter when the filter material of the electrofilter is nonconductive. If the electrofilter is conductive it can function as the first electrode as well as a filter. A second electrode is disposed on the filtrate side of the electrofilter. A method for continuously separating a liquid from an aqueous suspension while reducing membrane or filter fouling includes providing a crossflow apparatus having an electrofilter disposed therein; pumping the aqueous suspension into the crossflow aparatus at a pressure adapted to cause flow of filtrate through the electrofilter; and concurrently with pumping the suspension into the apparatus supplying electrical energy to the electrofilter at a voltage adapted to reduce fouling of the electrofilter.

Abstract: A circuit arrangement for protection against fault currents in power supplies, having an energy storage means, such as frequency converters for the operation of three-phase motors. The arrangement comprises two identical detector windings in the supply lines leading to the power supply so that a differential current detector winding connected with such detector windings causes a circuit breaker device to be actuated when a given value is exceeded. This circuit breaker device interrupts all the supply lines between the power supply and a load connected therewith by means of switching paths. This ensures that despite the energy stored in the power supply there is rapid and reliable switching off of the load should a fault current occur.

Abstract: In this device for indicating ( 10 ) pretensioning forces in a tensioning element ( 7 ), such as tie-down straps or tie-down ropes, the spring surrounds the tie bolt ( 3 ) which is located on the loop of the tie-down strap, and in response to weak forces describes a path ( 6 ) which is easily visible. The combination of two components which differ in shape allows the spring ( 1 ) to maintain its shape and spring constant. As a result, the pretensioning force is indicated directly, yet the spring is not subject to an additional load under high tensions but is protected by positive engagement.

Abstract: For ploughing cables, a corresponding laying plough (18) has a cable chute (26) serving to guide the cable (10 ... 12). When only one cable is laid, a relatively narrow cable chute can be used, the clear width of which is slightly greater than the diameter of the cable. To lay a plurality of cables next to one another, the cable chute (26) would need to be of correspondingly wide dimensions, which requires an increased traction outlay for the laying plough (18) and a greater mound in the ground. The object of the invention is to permit the laying of a plurality of cables (10, 11, 12) without the abovementioned disadvantages. The process according to the invention provides that the cables (10 ... 12) are guided behind or above one another in a common vertical plane through the cable chute (26), and are only re-oriented shortly before the cables (10 ... 12) emerge from the cable chute (26). For this, the laying plough (18) according to the invention has a specially designed cable chute (26). The invention is particularly suitable for burying cables (10 ... 12) in sand, but also for burying other objects in sand which are to be laid in the ground (17), for example pipes, tubes or the like. <IMAGE>

Abstract: For laminating a web (3) with a stretched web (2), the stretching operation for the web (2) is immediately followed by feeding in the unstretched web (3) and laminating it on to a certain extent within the stretching apparatus (4) by utilising the stretching heat - preferably after independent preheating - so that a heat-laminated multilayered web (13) is formed, in which both webs (2 and 3) may consist of the same or the same type of material, which is particularly favourable for reprocessing. The advantages of such a composite web comprising a stretched web and an unstretched web are thus achieved without adhesive being required for forming the bond.
