Abstract: Abstract An electronic ballast for a dicharge lamp (8) for restricting and stabilizing a current, said ballast comprising a high frequency oscillator connented to a source of direct current, said oscillator consisting of two series connected transistors (1, 2), a base drive transformer (3) connected there between and bringing transistors (1, 2) into alternating phase operation, an inductor (7) connected in series with the primary winding (4) of a transformer (3), and a resonance capacitor (10, 11) in the latter series circuit between a lamp (8) and a source of current, as well as a filtering capacitor connected between the terminals of a source of direct current and having high charging ability.          An object is to  reduce the radio interference level produced by a ballast and on the other hand to reduce RMS value of the ripple current of a  filtering capacitor as well as the switching losses of transistors. This is achieved by connecting one (8a) of the electrodes of lamp (8) by way of resonance capacitors (10 and 11) to each opposite terminal of said source of current. The circuit solution further includes diodes (23, 24) connected parallel to capacitors (10, 11) for stable circuit operation despite the negative resistance on the part of a lamp.

Abstract: ABSTRACT OF THE DISCLOSURE     A sloped bin grain elevator is formed of preformed structural components and has the bins therein sloped at or near the angle of repose at the stored material to create a non-confined grain flow pattern.  The elevator building structure includes an inclined base, a sloped roof and side walls as well as end walls and a plurality of interior partitioning walls.  Wach bin in the elevator has a series of staggered intermediate levels so as to divide the depth of the bin into various layers.  The staggered intermediate levels of the bins are formed by a series of precast slabs, the width of each slab being slightly less than half the width of the bin, the slabs being positioned and to end in a staggered pattern whereby the entire length of each bin forms one intermediate continuous layer of slabs.

Abstract: ABSTRACT          The output of a load, e.g. an incandescent lamp, connec-ted to an A.C. power source is maintained constant for varying supply voltages by decreasing the duration of current pulses con-ducted by a transistor as the supply voltage rises.  The transis-tor is connected in series with the load and is controlled by an operational amplifier.  One input of the operational amplifier is fed with a rectified unsmoothed A.C. voltage derived from the supply voltage and the other input is fed with a voltage which is the sum of a D.C. voltage held constant by a zener diode and a superposed rectified and smoothed voltage varying with the supply voltage.

Abstract: Abstract of the Disclosure A two-chamber container A two-chamber container is specified for two gas-pressurized components kept separately in a container, for example liquids which are miscible. An outer container (1) takes up a first component and is provided with a safety valve (2) whose outlet passage (5) leads from the interior of the outer container (1) to the outside and is adapted to be closed by a plug (14). The second component is received in an inner container (7) in the interior of the outer container (1). The inner container (7) is an entirely separate, self-contained vessel supported in the interior of the outer container (1). The inner container (7) has a desired urpture site (10) which can be broken by force acting from outside, possibly by pivoting or pushing-in th safety valve (2). In this manner ready communication is established between the interiors of the two containers so that spontaneously complete mixing of the two components is warranted.

Abstract: Abstract of the Disclosure Helical scan magnetic recording system of the type where  time  compressed  audio  signals  are  recorded  in extensions of the video tracks.  In order to avoid a time delay of the reproduced audio relative to its original relationship to the video when played back, additional audio recording heads are located on the helical scanner so as to record the audio information on tracks that when played back are reproduced sufficiently in advance of the video to allow restoration of the original audio/video synchronism.  The arrangement can thus can be employed to produce pre-recorded tapes having time advanced audio such  that  synchronous  audio/video  is  reproduced  on conventional playback reproducing systems.

Abstract: Abstract of the Disclosure An airline lubricator in which a diaphragm is disposed in a closed annular chamber surrounding an axial air passage to divide the chamber into an air pressure chamber and a lubricant reservoir.  The air pressure chamber is coupled by an angulated pressure tube to the primary air passage adjacent the lubricator inlet.  A metering tube and adjustable screw arrangement at the output of the reservoir control the amount of lubricant fed to the primary air passage as a function pressure drop across the primary air path.  A ball-type check valve including an adjustable valve seat is disposed across the primary air path in opposition to the metering tube for preventing passage of lubricant in the absence of primary air flow.

Abstract: A METHOD AND MECHANISM FOR PRELIMINARY ANCHORING OF A WIRE      ROPE BOLT            ABSTRACT OF THE DISCLOSURE            The invention relates to a method and mechanism for preliminary anchoring of a wire rope bolt in a bore by means of friction. The object is to eliminate the need to use wooden wedges or to bend the strands of the rope backwards, procedures which are time-consuming. In accordance with the invention, a permanent deformation is produced in the wire rope bolt in such a way that friction force is produced when parts of the bolt press against the wall of the bore. The mechanism may comprise, fitted at a point prior to feeding rolls, a bending roll, which bends the wire rope before it is fed into the bore.          The circumference of the feeding roll can be V-shaped, in which case it causes the bent wire rope to rotate and to become helical.

Abstract: ABSTRACT         The drainage channel comprises a channel body (1), cast frame (2) and cast grid (3). The support surface of the side walls (11) of the channel body (1) are of stepped construction, with a raised external supporting rib (13).   The frame (2) is rectangular, with a lowered support rail (28) as support for the side ribs (30) of the grid (3).   On the outside the frame (2) has detachably fastened brake lugs (23), which in the installed state prevent displacement of the frame (2).    Locking bar holders (44) of roughly H-shaped cross-section are disposed in the side walls (11) some distance below the support surface.    These locking bar holders form a closure between the interior of the channel body and the exterior.  On the inside a side wall (79) forms an obtuse angle with the wall (75), so that the locking bar (45) can easily be turned into the inner recess (78). A drainage channel of this kind can easily be adapted to the different heights in the case of stepwise laying of the base course and cover layer, and it can be cast in a simple manner in polyester concrete.   At the same time it also has a plurality of anchoring ribs at the side of the retaining lugs, thus ensuring good anchorage in all directions.                                (Figures 3 and 7)
