Title: Method of calcining diatomaceous earth
IPC: C04B20/04
Filed: 1934-10-15
Abstract: <PICT:0445776/III/1> Diatomaceous earth is calcined by conveying the comminuted material through a heating zone through which combustion gases are caused to flow in countercurrent, a portion of the necessary fuel being mixed with the earth, the remainder being separately introduced throughout the calcining operation and sufficient air being supplied to complete the combustion of both portions of fuel.  Suitable fuels for admixture with the earth include liquid fuels such as petroleum distillates and asphaltic oils or solid fuels such as caking coals, bituminous coals, lignites, oil shales, vegetable fibres, sawdust, diatomaceous shales containing bitumen &c., anthracite, cokes, &c.  If the earth to be treated contains combustible material, the amount of fuel admixed therewith should be correspondingly varied.  The fuel selected may be one which on consumption produces an ash adapted to decolorize the earth by reaction with the iron compounds therein.  As shown, the earth is introduced from a bin 20 into hot combustion gases from a furnace 17 and the resulting suspension, together with flue gases from a flue 15, are forced by a blower 16 into a cyclone or other separator 23. A suction blower 25 discharges dust and cooled gases to a baghouse or the like while the dried powdered earth collects in the separator and is continuously removed by a conveyer 29.  The addition of solid or liquid fuel is made in the conveyer 29 from a bin or tank 33.  The mixture of earth and fuel passes into a rotary kiln 10 and after passing therethrough in countercurrent with gases from a burner 13 is discharged at 32. By means of the flue 15, blower 16 and separator 23, soot is collected from the combustion gases on to the grains of earth and is returned therewith to the kiln.  The combustion may be controlled by varying the proportion of the total fuel admixed with the earth or by varying the air supply, the lower limit being the quantity of air necessary to burn all the fuel.  Instead of a rotary kiln, any elongated kiln, moving or stationary may be employed.  The calcination temperature is generally between 1500 and 1700 DEG  F. The resulting earth may be saturated with a semi-fluid such as asphalt for the production of battery boxes or the lining of acid tanks.  Specification 445,777 is referred to.ALSO:Diatomaceous earth is calcined by conveying the comminuted material through a heating zone through which combustion gases are caused to flow in counter-current, a portion of the necessary fuel being mixed with the earth, the remainder being separately introduced throughout the calcining operation and sufficient air being supplied to complete the combustion of both portions of the fuel.

Abstract: 286,001. Wilmotte, R. M. Nov. 27, 1926. Brush - hnlder.s; improving commutation, auxiliary means for.-In electrical machines employing a segmental commutator, the circuit of each segment is linked with a magnetic core the reluctance of which is so varied as to produce during the period in which the segment is undergoing commutation a balancing E.M.F. in opposition to the commutating E.M.F. As shown in Figs. 1 and 2, the segments of a commutator 10 associated with relatively rotatable brush-gear 17 are connected to the windings 12<a>, 12<b>, 12<c> of a transformer or other machine through coils 29<a>, 29<b> &c. on magnetic cores 24<a>, 24<b> &c. The cores are provided with air gaps 23, and a flux is produced therein by exciting windings 28<a>, 28<b> &c. The required balancing E.M.F. is generated in the coils 29<a>, 29<b> &c. by means of inductors 27 moving synchronously with the brush-gear through the air gaps 23. The inductors are provided with tapering extensions so dimensioned as to vary the effective width of the air gaps to produce a balancing E.M.F. of a suitable characteristic, and are of a length bearing the same ratio to the length of the air gaps as the width of the brush bears to the width of a segment. The inductors are staggered alternately and rotate with the brush-gear when the latter rotates; the brush-gear and inductors may however, be fixedly arranged to co-operate with a rotary commutator and rotary cores. The invention is described more particularly in connection with commutator switch converters, frequency changers, and phase changers, but is also seated to be applicable to dynamo-electric machines to enable the brushes to be shifted for effecting speed control in the case of a motor, and voltage control in the case of a dynamo.

Abstract: 1478119 Hydraulic copying attachments INDEX - WERKE KG HAHN & TESSKY 5 July 1974 30033/74 Heading B3T A copy turning attachment comprises a copying slide 18 attachable to a feed slide and actuated by fluid operated piston and cylinder means 20, 22, 30 under the control of a slide valve 36 and a pivotable feeler member 66 which is either actuatable by a template (not shown) which is engaged by a tracer 76 on one of the feeler arms 72 to perform a true copying cut or by a stop member 84 which is adapted to be contacted by a tracer 78 on another of the feeler arms 74 which controls approach and rough cylindrical turning operations on a workpiece prior to the copying cut determined by the template. The stop member 84 is pivotally attached to the copying slide for movement about an axis parallel to the pivot axis of the feeler 66. The feeler 66 has a third arm 70 which engages the end 38 of the control valve 36 which is displaceable in relation to the arm 70 and so control the fluid flow to the cylinder 28, 30 for displacing the copying slide. In operation, a magnet 82 is energized to repulse the feeler arm 70 and permit initial displacement of the valve 38 by spring 42 to effect infeed of the slide and cutting tool 16. This movement of the copying slide brings the tracer 78 of the feeler arm 74 into contact with an inclined cam surface 94 of the stop 84, this causes the feeler 66 to pivot and its arm 70 displaces the control slide 38 to stop the movement of the copying slide. The point of contact between the tracer 78 of the feeler 66 and the cam surface 94 limits the infeed movement of the copying slide. The limit of the infeed may be adjusted by pivoting the stop member 84 against its spring 92 by way of computer controlled plungers 86 to alter the position of contact between the feeler and stop, thereby a succession of infeeds may be provided until the tracer 76 contacts the template whereby the control of the slide is determined by the template contour.
