Abstract: Process for the manufacture of novel dioxaheterocyclic compounds Abstract The invention relates to processes for the manufacture of novel dioxaheterocyclic compounds of the general formula I        in which Rl represents an unsubstituted or substituted aromatic or heteroaromatic radical or an unsubstituted or lower alkylated, mono- or bi-cyclic cycloaliphatic hydro-carbon radical or an a-branched aliphatic hydrocarbon radical, each of R2 and R3, independently of the other, represents hydrogen or lower alkyl, and each of R4 and R5, independently of the other, represents hydrogen, lower alkyl or halogen, and A represents the radical -O-R6, wherein R6 represents hydrogen or an unsubstituted or sub stituted aliphatic or araliphatic hydrocarbon radical or A   represents the radical -N  in which each of R7 and R8, independently of the other, represents hydrogen or lower alkyl, or, R7 and R8 are bonded to one another and, together with the adjacent nitrogen atom, represent unsubstituted or lower alkyl-substituted tetra- to hexamethyleneimino or 4-morpholinyl, and the divalent radical in formula I is either in the 4,5- or the 5,6-position and correspondingly R4 and R5 are in positions 6 and 7, or 4 and 7, respectively, of the benzodioxole skeleton, of salts of compounds of the general formula I in which A represents OR6 wherein R6 represents hydrogen, with bases, as well as of acid addi-tion salts of compounds of the general formula I in which the radical Rl is of basic character. These novel substan-ces have a diuretic activity and, in addition, a uricosuric activity, and can be used, preferably in the form of corresponding pharmaceutical compositions, for the treatment of oedema and hypertension.

Abstract: ABSTRACT OF THE DISCLOSURE     The specification describes a cable winding system for electrically powered vehicles or working machines operated in cramped underground conditions and receiving its driving power through a flexible cable.  The excess length of the cable depending on a given position of the vehicle is collected within an assembly mounted on the vehicle.  A cable is wound on a collector which rotates about a vertical axle, disposed on the center line of the vehicle.  The final exit point for the cable relative to the vehicle is determined by a guide means which is mounted on the end of an extension arm swivelling concentrically with the axle of the collector.  A moment effecting the winding and tightening of the cable acts between the extension arm and the collector.

Abstract: Check Valve Abstract A low pressure drop check valve includes an apertured, streamlined guide body (45) mounted on struts (40) which accommodate thermal and fluid loading and also includes a streamlined poppet or valve element (35) disposed within a housing.  Forward flow through the valve unseats the valve member, which receives therewithin a face (50) of the guide body allowing flow around the valve member and guide body. Reverse flow is accommodated by apertures (60) and (65) in the guide body, flow through the aper-tures being applied to an inner surface of the valve ele-ment, thereby seating the valve element for blocking such reverse flow.  The check valve is also provided with means (70) and (85) for minimizing valve element oscillation and bounce.  Maintenance of the valve in an open condition is enhanced by maintenance of a low pressure region down-stream of the poppet.

Abstract: METHOD AND APPARATUS FOR DEWATERING      A SLURRY OF FINE PARTICLES     ABSTRACT OF THE DISCLOSURE     A method and apparatus for dewatering a slurry of fine particles including a dewatering table and a forming fabric passed across the table.  Vacuum is applied to the table and the forming fabric.  A first slurry of particles is introduced through a primary headbox to the forming fabric.          A second slurry of finer particles is introduced through a secondary headbox to the forming fabric.  The primary and secondary headboxes are positioned relative to each other and the table so that the first slurry is introduced to the forming fabric before the second slurry as the fabric moves across the table.  Vacuum is applied to the first slurry to form a mat of first slurry particles upon which the second slurry of finer particles is deposited to be dewatered thereby minimizing the loss of fine particles through the forming fabric and maximizing the amount of retained dewatered particles.

Abstract: ABSTRACT          Electrophotographic imaging apparatus, particularly for color proofing, is provided for normal daylight operation including a light-tight housing having a framework mounting plural functional processing stations, namely, a charging station, an imaging or exposure station, a toning station, an image transfer station and a cleaning station, all interior of the housing.  An electrophotographic member carrying platen is translated linearly along a guide the length of the framework along a predetermined, precisely defined horizontal path.  A copyboard is disposed below the carriage at the imaging station carrying a pattern carrying transparency.  Starting from a home position, the platen is translated past the charging station; a surface charge potential is applied.  The charged member is brought to the imaging station, the copyboard elevated to engage the intimate charged surface and radiant energy from an interior disposed source is projected through the transparency forming a latent electrostatic image and the copyboard is lowered.  The platen then enters the toning station where one of a plurality of available toning modules has been raised to toning proximity to said surface for toning with liquid toner carried by said selected module during passage of said surface past said module.  The selected module is lowered and the carriage translated to the transfer station where a pre-wet transfer sheet is engaged with the toned surface and the toner image transferred thereto.  An electrical bias voltage is employed during transfer.  The transfer medium and electrophotographic member are separated and the platen translated to the home position as any residual toner and residual charge are removed.  Pins and sockets are provided for cooperation with suitable registration maintained.  The process is repeated but with different transparencies and toners to produce the color proof desired.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus relating to the real time automatic detection and classification of character-istic type surface imperfections occurring on the surfaces of material of interest such as moving hot metal slabs produced by a continuous steel caster.  A data cam-era transversely scans continuous lines of such a surface to sense light intensities of scanned pixels and gener-ates corresponding voltage values.  The voltage values are converted to corresponding digital values to form a digital image of the surface which is subsequently processed to form an edge-enhanced image having scan lines characterized by intervals corresponding to the edges of the image.  The edge enhanced image is thresholded to segment out the edges and objects formed by the edges are segmented out by interval matching and bin tracking.  Features of the objects are derived and such features are utilized to classify the objects into characteristic type surface imperfections.
