Abstract: The invention refers to a transducer-rectifier for operation of a gas discharge pipe from a direct current source and containing a transformer, over whose secondary winding (D) the gas discharge pipe is connected and over whose primary winding (B, C) an RC-circuit (A) in a series with a power transistor (T) base-collector circuit connected. The power transistor's (T) emitter is connected to the earth clamp of the direct current source, while a socket on the primary winding (B, C) is connected to the plus clamp of the direct current source, whose socket divides the primary winding in a running winding (B) and a feedback winding (C) for the RC-circuit (A). According to the invention the winding relationship between the running winding (B) and the feedback winding (C) on the transformers primary side amounts to at least 2. The core of the transformer (E) is of the pot-core type with an air gap of no greater than 0.5mm and the effective output transistor's (T) small signal short circuit forward current amounts to between 90 and 215.<IMAGE>

Abstract: A tamping machine intended for tamping on the open track and below switches and cross overs. It is equipped with independent tamping units arranged on opposite sides of each line of rail and each connected to the chassis by a mechanism comprising: a transverse slideway actuated by a first piston-cylinder unit; a slide block mounted on the slideway and on which the tamping unit is articulated; an arm fastened to the tamping unit; and a connecting rod connecting said arm to the chassis. The slide block of the outer unit is fastened on the slideway while the slide block of the inner unit is movable on said slideway and driven by a second piston-cylinder unit. Thus, the transverse trajectory of the tamping tools is sufficiently flat to avoid a correction of their depth of penetration upon the tamping of long ties.

Abstract: In the process for electrowinning of zinc from acid zinc sulfate electrolyte, electrolyte is recirculated to the cells and a portion of the electrolyte is returned to the leaching operation of zinc-bearing material. By only returning electrolyte that overflows from electrolytic cells that contain new and/or recently cleaned anodes to the leaching operation, the amount of sludge in the cells can be reduced, the period between cleanings of cells can be lengthened and the amount of addition agent for controlling the lead content of deposited zinc can be reduced. Electrolyte overflowing from only those cells that contain new and/or recently cleaned anodes is diverted and kept separate from recirculating electrolyte from all other cells by providing separate means for collecting and transferring electrolyte to the leaching operation. Such means may consist of two separate overflow pipes in the cell overflow means, and shut-off means, whereby electrolyte can be directed either into the recirculation circuit or to the leaching operation, or both, as required.

Abstract: The invention relates to a method and an arrangement for image stabilization of an electro-optical system, for example a sight, a camera or the like, which is subjected to vibrations or other undesirable movements and in which the optical image information is converted into electrical signals, for example a TV or IR system, and is stored in a memory 9. The vibration spectrum of the system is sensed by means of one or more sensors 1 which generate electrical signals which represent how much the image is to be translated vertically and/or laterally in order to compensate the vibration movements to which the system is subjected. The signals are supplied to a digital processor 10 which is arranged so as to transfer the stored information from said memory 9 to a second memory 11. The image digitally stored in the first memory 9 will then be translated vertically and/or laterally corresponding to the instantaneous vibration aberration. <IMAGE>

The outfeed slide co-acts with a motor (36) drivingly operating the slide (40) having an L-shaped cut-out (100) in which a slide driver (94) eccentrically mounted on the crankshaft (92) of the motor is intended to move. When dispensing a metered quantity of powder, the slide driver moves in the transverse leg of the L-shaped cut-out during a first half of a revolution so as to draw out the operating slide (40) and the outfeed slide (60). The slide driver then passes into the longitudinal leg of the L-shaped cut-out and releases its engagement with the operating slide (40), whereupon the outfeed slide (60) and the operating slide (40) are snapped back by the rubber band (78). The outfeed slide therewith strikes against the outfeed box (22) and generates a shock wave which shakes any arched or bridge-like incrustation present in the storage container (18).

Abstract: A method of analyzing a body (log) containing elements (e.g. knots) having different densities than the remainder of the body by passing electromagnetic energy from at least one source for substantially symmetrical bodies (pruned logs) or at least two sources through the body and sensing the amount of energy passing through the body from each source by sensors mounted opposite each source. Each sensor is formed by an array of discrete detectors positioned in side by side relationship opposite their respective sources. The amount of radiation passing through the body is detected as the body passes between the source(s) and its (their) respective detector(s) and a longitudinal plan is generated based on the radiation detected from each of the sensors over at least a preselected length of the body. For non-symmetrical bodies the longitudinal plans are then analyzed to identify the same element in each of the plans and then the body is reconstructed in a plurality of cross sections representing discrete lengths of the body shorter than the selected length with the detected elements positioned in the cross section. A longitudinal axis of the body is selected based on the shape of the body and the plurality of the cross sections are collapsed along lines parallel to the selected longitudinal axis to provide an accumulation of the overlying elements along the axis in a single cross section representative of the length of body being collapsed. This system provides a means for a real time analysis of a body such as a log to determine the location of defects and generate a rotation decision for rotating the log for presentation to the headrig to permit the optimization of a sawing solution for the log. The system may also be used to determine a bucking solution to select the length of the log for which the sawing solution is determined.
