Abstract: 885,977. Washing granular materials. EDER, T. April 3, 1958 [April 3, 1957; June 11, 1957; Aug. 7, 1957], No. 10881/58. Class 82(2). In a process for separating granular material by gravity into two or more end fractions by subjecting the material while falling to the action of an upwardly moving current of liquid with at least two sections which are effective as separating stages delivering a subsiding and an entrained grain fraction of each section is collected in successive sections of the current each of which acts as a separating stage and shows a laminar flow pattern, the subsided fraction of at least one section being branched off, transferred by gravity outside the upwardly moving current and introduced in and distributed over the cross section of the inlet zone of a lower flow section, and the grains entrained by the current being withdrawn together with liquid in one end stage as an end fraction and at least the subsided fraction of the other end stage being withdrawn as another end fraction. Fig. 5 shows a two-stage classifier in which granular material R is divided into subsiding and rising fractions while in stage A, washing liquid Z entering through screen 66. The rising fraction is withdrawn as one end fraction Fl, while the subsiding fraction slides down wall 61, is collected in pipe 67 and is fed by this pipe to the inlet of stage B. The fraction which subsides in this stage slides down wall 61 or the wall of pipe 67 and leaves the classifier as second end fraction F2. The apparatus may be vibrated by eccentric discs 71 carried on the shaft of electric motor 70 which is mounted on wall 61. Alternative embodiments of the apparatus are disclosed in which (a) subsided fractions are branched off into secondary passages formed between the main wall and partitions, and (b) secondary passages are formed by separate pipes which bypass at least one separating stage and discharge into lower sections. The example relates to the classification of raw sand.

Abstract: 789,735. Photogranhic enlarging apparatus. AGFA CAMERA-WERK AKT.-GES. April 14, 1954 [April 30, 1953], No. 11073/54. Class 98(1) In a photographic enlarger a coupling between the lens carrier and the negative carrieris associated with an indicator which provides a characteristic indication when the enlarger is in focus. The equation x y =f<SP>2</SP> is used, where x is equal to the distance between the object space focal point and the negative plane and y is equal to the distance between the other focal plane and the positive plane, f being the focal length of the enlarger lens. In one form a right angle triangle ABC has base equal to x + y and height equal to f. A lever 8 and plate 16 are independently pivoted at A and the angular position of the plate is determined by the co-action of rollers 17, 18 with tensioned band 13. The coincidence of the axis of the arm 8b of lever 8 with the line AC is indicated by breaking of contacts 20, 20a and 21, 21a and the extinction of lamp 22. Arm 8a of lever 8 bears on roller 9 and spring drum 14 is provided to tension band 13. Alternatively the band 13 may extend to B and the arm 8a be provided with rollers similar to the rollers 17, 18. The straight line from A at right angles to AB may alternatively be embodied in a projected beam (Fig. 1, not shown) forming an image on a projection screen and its coincidence with the line AC indicated by reference to a mark at the point C on the screen. The points B, A and C may be movable relatively to the object plane 4, lens 5 and image plane 1, respectively, on changing the focal length of the lens. In another form using a Wheatstone network, helical focusing of the lens controls the position of a sliding contact 31 on an arcuate resistance 30 arranged on the stationary member of the lens mount. The resistance tapped therefrom is proportional to x. A rectilinear resistance 32 is fixed parallel to the column of the enlarger and the bracket 3 (Fig. 2) carries a sliding contact 33 which taps therefrom a resistance proportional to y. The circuit is completed by two resistances 35, 36 each porportional to f and a galvanometer 34.

[Class 38 (v)] [See also Group XXXVIII] Direction-indicators are controlled by a metal ball mounted in a tube on the steering wheel which runs to the end of the tube as the wheel is turned to bridge contacts in the indicator circuits. The tube can be tilted by hand to give an indication before a turn is initiated or the contacts may be bridged by hand - operated push - button switches. A " straight-ahead " indication may be given when the ball is centrally disposed in the tubes. As shown in Figs. 4 and 5, a short tube of insulating material is pivoted at b, and carries ball C and contacts b<1>, b<2>. When the wheel is turned, the ball runs to one end or the other and bridges contacts b<1> or b<2> to close the respective indicator circuit. To indicate a turn before the wheel is moved, the tube may be swung by hand about b. Spring B<1> holds the tube in its normal position. If small movements of the steering wheel are not to close the indicating circuits, a long tube, as shown in Fig. 6, is provided. As tilting such a tube to give an initial indication is impracticable, hand-operated press-button switches D, Fig. 9, are provided at the ends of the tube to bridge the contacts when required. Specifications 271,731 and 326,879, [both in Class 38 (v)], are referred to.

[Class 110 (iii)] [Also in Groups XXVII and XXXIII] An aircraft power plant comprises a twostroke internal combustion engine driving a propeller and a centrifugal compressor which constantly delivers air directly to the engine by which it is driven and a turbine supplied with gases from the engine which drives an axial flow compressor supplying air to the centrifugal compressor. The exhaust from the internal combustion engine A, Fig. 1, driving a propeller B and a centrifugal supercharger C, passes to a turbine D which drives an axial flow compressor G which supplies air to the supercharger C. The turbine D may, in addition drive a variable pitch pusher propeller J or may be geared to the propeller B which may be of the contra-rotating type. The propeller J may also be used separately as a tractor. An intercooler H may be provided between the compressors C and G. The propeller J may be used to control the speed of the turbine D and the energy of part of the whole of the exhaust gases may be increased by passing them through a combustion chamber F, which may be supplied with air from the discharge of the supercharger C through the passage C<1>. In a modification, the exhaust gases from the turbine D may pass to a jet nozzle and the turbine controlled by varying the area of the nozzle or by by-passing some of the exhaust gases. In a further modification, the exhaust gases from the turbine D are employed in a further turbine which may drive a variable pitch propeller which may be coaxial with the engine driven propeller B or alternatively may be geared to one part of a contrarotating propeller the other part of which is driven by the engine. The two parts of the contra-rotating propeller may be independent or geared together. The turbine and the engine may also drive a single propeller. Provision may be made for reheating the gases between the two turbines. In another modification, the gases from the engine are divided, part passing to the axial flow compressor turbine D and part to a separate power turbine driving a propeller. In both of the arrangements employing two turbines, the turbines may be controlled together by by-passing some of the gases direct to the exhaust, and the power turbine individually controlled by varying the pitch of the blades of the propeller driven by it. The gases may be reheated before passing to the turbines. In all the above arrangements, the exhaust gases from the turbine D may be used to preheat the air entering the engine manifold A<1>, and the centrifugal compressor may be of the multi-stage type. According to the Provisional Specifications, the axial flow compressor may be formed in two parts geared together to run at different speeds and the gearing between the turbine and its propeller may be of the variable ratio type.
