Abstract: 231,686. Borrmann, C. H. May 2, 1924. Distilling plant; hydrocarbons, distilling; separate heater and evaporator apparatus.-In distilling mineral oils, tars, fatty acids &c. the crude liquid is passed in succession through tubular heaters at successivelv increased temperatures and is passed through vapour separators between the heating stages. The heaters 3, 16 consist of coiler tubes heated by furnace gases which pass over the heater 16 in the same direction as the oil flows through it and over the heater 13 in countercurrent. A by-pass 35 and valves 36, 37 are arranged to vary the passage of the flue gases. Oil from a tank 1 is forced by a pump 2 through the heater 3 and to a distilling column 4 to which superheated steam is admitted by a pipe 5. Light oil vapours pass through reflux condensers 7, 8 to a final condenser 9. The unvaporized oil passes by a pipe 13 to a tank 14 from which it is forced by a pump 15 through the heaters 16 to a distilling column 17 in which it falls in countercurrent to superheated steam admitted through a pipe 18 having downwardlydirected perforations. The pitch-outlet pipe 26 is covered by a hood 28 and has a small outlet opening 29 in the base so that the column may be drained. The vapours pass through a spiral outlet passage 30 to separate entrained liquid and through reflux condensers 20, 21 to a final condenser 22.

Filed: 1964-03-16
Abstract: 1,062,451. Moulding fibre resin sheets; laminating. COMPAGNIE DE SAINT-GOBAIN. March 16, 1964 [March 15, 1963], No. 11009/64. Headings B5A and B5N. A sheet of fibre-reinforced resin is bent into an arcuate shape by feeding the sheet on to a suitable shaped moving surface, heating the sheet thereon until it has set hard, removing the sheet and finally cutting it into required lengths. The sheet may have longitudinal corrugations or ribs &c. which may be formed before the sheet is applied to the moving surface. A glass fibre-mat, formed at 1, is fed on to a sheet 2 of cellophane on to which a polymerizable resin 4 has been applied. A top sheet 5 of cellophane is then applied between rollers 6 and 7, the edges of the cellophane sheets being welded together. The sheet 8 then formed is then drawn over a series of corrugating rollers 9 on to the shaped rim 10 of a rotating spoked wheel 11 and passes through ovens 14, 14a-f in which the polymerizable resin is fully hardened. The hardened sheet is prised from the rim 10 over rollers (63), (64) and member (62) (see Fig. 8, not shown), its edges being trimmed by saw 17, and is then guided on to the arcuate surface of a trolley 46. The sheet is guided over the arcuate surface by rolls (43) and strikes a microswitch (51) which actuates a transverse saw 18 to cut a length from the sheet. At the end of its stroke the saw actuates another microswitch to connect suckers (49) to a vacuum to firmly hold the severed length. The trolley is then retracted along rails 48, the upper frame member 45 pushed sideways by rams (52) (53) and the lengths deposited on to a suitable take-off device. The sheet is drawn over the wheel by means of releasable suction cups carried by endless bands located at station 15. The rim 10, corrugated as in Fig. 5 (not shown) is carried upon end cross-members of the spokes by perforate flanges (23a), (23) and imperforate flanges (22, 22a, in Fig. 3, not shown), a cavity (25) being formed between the rim, flanges (23), (23a) and a cylindrical sheet (26), coaxial with the wheel of a heat insulating material. The ovens co-operate with the flanges (23), (23a), as in Fig. 5, the heated air f1 passing through perforate plate (32) directly on to the sheet 8, the air f2 being additionally heated at (33) and passing through plates (23), (23a) to heat the undersurface of the rim 10 and thus the undersurface of the sheet.

Title: Process for treatment of cereals
IPC: B02B1/00
Filed: 1944-06-09
Abstract: 589,344. Treating grain. HUZENLAUB, E. G., and ROGERS, F. H. June 9, 1944, No. 11082. [Class 58] A method of converting and enriching the endosperm of cereal grain comprises the steps of placing the grain in a closeable vessel, creating a vacuum in the vessel, admitting warm water for steeping the grain and for obtaining a solution of vitamins and like soluble bodies whilst maintaining said vacuum during a period to accelerate influx of the solution to voids in the endosperm, applying heat and pressure within the vessel for endosperm absorption of the solution, separating the steeped grain from the steeping solution, maintaining the steeped grain for a period of time under conditions to promote enzymic reaction therein, treating the grain with live steam under pressure, suddenly releasing the pressure at a high rate of flow, and then drying the grain. When treating wheat for the manufacture of baking flour the step of treating it with live steam is omitted. Referring to the drawing, grain is fed by an elevator 1 to a bin 3 from which it passes through a valve 7 to a steeping tank 6. The tank is subjected to a high vacuum by means of a pump 13 and when the desired absence of pressure is reached, steeping water, from 40‹C. to 70‹C., is admitted to the tank from a tank 9 through conduit 10. Vacuum valves 14, 36, are then closed and steam is led to tank 6 by a pipe 16 to maintain the desired temperature, and during this steeping process, which lasts for one or two hours, compressed air is supplied to the tank 6 by a pipe 15. Valves 53 are then opened to withdraw the steeping water, which may be stored for use with a later batch, and the wet grain is delivered by a shoot 20 to one of two chambers 18 where the temperature of the grain is maintained. Here the grain is left for several hours to enable natural enzyme reaction to take place. To accelerate the enzymic reaction diastase or other enzyme bodies may be added to the grain or liquid prior to steeping or by allowing the steeping water to be discharged with the grain to the chamber 18. After treatment in chamber 18 the grain is discharged into a dryer 22 where it is treated with steam by opening a valve 34, a further release valve 38 being subsequently opened to cause sudden discharge of the steam. Drying under vacuum then follows, as in Specification 538,437, the vacuum being produced by pump 13 and the drying being effected by supplying steam to a jacket and tubes of the dryer through steam line 32. The dryer is rotated during this operation and is eventually stopped to discharge the dried grain to a conveyer 41.

Title: Improvements relating to dynamo electric machines
IPC: H02K23/02
Filed: 1945-05-03
Abstract: 593,817. Exciting dynamo - electric machines. MACFARLANE ENGINEERING CO. Ltd., MACFARLANE, J. C., and MACFARLANE. W. I. May 3, 1945, No. 11224. [Class 35] A D.C. machine having armature reaction compensation and distributed field windings and which may be of the construction described in Specification 519,538, has means for controlling its output by causing a change in flux acting on those 'armature coils in the commutation zone and short-circuited by the brushes. As shown, stator windings 18 include both the exciting and compensating windings, the interpoles on axis Y-Y having controlling windings 19, which, when energized produce a circulating current in the armature winding 21a short-circuited by the brushes 23. This circulating current aids or opposes the main flux of the machine. The control is normally used for transient changes and compounding-up against downward fluctuations can be achieved by energizing the interpole winding through a transformer from the controlled circuit, or by shunting it with an inductive circuit which resists current changes so that these occur to an increased extent in the interpole winding. A drooping characteristic may be obtained by reversing the transformer connections, shunting the winding with a non-inductive resistance, or by short-circuiting the interpole winding to produce a shading effect. If a steady control is needed, two control coils may be used, one having a steady voltage applied to it and the other, opposing it, connected to the controlled quantity. Alternatively, both coils may be energized from the controlled circuit, but one may be shunted by a non-linear resistor as in Specification 566,168. In a modification, a single coil is used, energized from the controlled circuit through a bridge circuit composed of alternately connected linear and non-linear resistors. In a further form, the interpole winding may be connected to a winding on the main poles. In order to reduce the current in the shorted coils, split brushes, connected to windings on the main poles, may be used to increase their effect. These windings may be spread out with the compensating windings around the circumference of the machine, and in the case of a multi-pole machine displaced brushes may be used to produce the effect of split brushes.
