Patent ZA-845116-B (ZA)
Title: Improved pipe flushing device
Inventor: TASH GEORGE
IPC: B08B9/032
Filed: 1984-07-04
Abstract: The improved pipe flushing device comprises an elongated, elastomeric, hollow tubular member having a middle portion free to expand radially under water pressure. The rear Inlet end of the tubular member is fitted with a hose connector, while the narrow front outlet end of the tubular member contains a valve which opens upon expansion of the middle portion. The valve has a cage bearing a rear plate closure, and open sides and front. The rear plate is received in a transverse groove in the outlet, which groove is of a greater length than the thickness of the plate. The cage is gripped and held in a fixed position while the tubular member is in the relaxed unexpanded state. However, when the device is inflated by water pressure from a water hose connected to the inlet connector while in a water pipe, the middle portion thereof expands to meet the wall of the pipe. When the expansion is complete, the cage moves back in the outlet, the plate moving resrwardly in the groove to cause a mechanical vibration in the tubular member and water pipe. Waterthen by-passes the plate and passes through and out of the cage as a jet to break up a sewage clog. Upon expulsion of the jet, the middle portion contracts and the valve moves forward and closes, again causing sonic vibrations in the tubular member and water pipe. The expansion and contraction of the tubular member rapidly alternate to rapidly pulse water jets and vib ate the pipe to unclog the pipe.

Title: Pressure actuated fluidised bed furnace
Inventor: CROONENBROCK RAIMUND
IPC: F02C3/28
Filed: 1988-09-07
Abstract: A fluidized bed combustion system that can be operated or controlled under pressure is provided. To eliminate the erosion or abrasion to which heat exchangers located in a fluidized bed combustion chamber are subjected due to the flue dust contained in the flue gas, no thermal withdrawal or exchange takes place in the combustion chamber of the inventive fluidized bed combustion system, although the reaction conditions remain the same. At least one controllable line for returning to the combustion chamber part of the flue gas, if necessary cooled by heat exchangers variously arranged outside the combustion chamber, branches off from the flue gas line downstream of a dust separator that is disposed in the flue gas line downstream of the combustion chamber. The main area of application is the production of electrical energy and heat for the generation of steam, as process heat, or as heat for a remote site, by means of a fluidized bed combustion system that can be operated or controlled under pressure.

Title: Switch mechanism
Inventor: COOK DAVID LANGMAN
IPC: H01H71/58
Filed: 1992-07-21
Abstract: A switch mechanism opens a contact set (1,2) in the event of an undervoltage condition. The mechanism involves a lever assembly (3) biased by a spring (9) for pivoting about one or other of two fulcrums to open or close the contacts respectively. The undervoltage causes a solenoid (6) to release a plunger (7) which initiates operation about a fixed fulcrum (8). A reset device (10) is used manually to initiate operation about a movable fulcrum (4) provided that the voltage is sufficient. An arm (5) is deflected by the plunger to shift the movable fulcrum and also acts to restore the plunger during reset. The switch mechanism may be incorporated in a residual current device which provides the undervoltage condition on detecting an electrical fault. <IMAGE>

Abstract: PCT No. PCT/CH79/00059 Sec. 371 Date Dec. 28, 1979 Sec. 102(e) Date Dec. 11, 1979 PCT Filed Apr. 26, 1979 PCT Pub. No. WO79/01000 PCT Pub. Date Nov. 29, 1979. Electric welding sleeves used more particularly with larger pipe diameters have a heating wire winding which is under compressive stress due to the shrinkage of the sleeve member. This compressive stress and the elongation of the resistance heating wire occurring during the welding process can lead to a lateral displacement and contact with adjacent turns. The welding apparatus (4) used for welding such sleeves obviates these difficulties in that the overall welding time of the electric welding sleeve (15) is subdivided into a preheating time and a welding time. During the preheating time a partial power is used and during the welding time the full welding power. If the welding power is taken from an alternating current system the welding process can start with half the power by arranging a diode (8) in the welding circuit (2) and at the end of the preheating time the diode is bridged by a switching stage (10).
