Title: New or improved method of and means for treating flax hemp or other fibrous stems or straws
IPC: D01C1/04
Filed: 1920-09-30
Abstract: 173,591. Foster, F. G., (Mahy, I. J.). Sept. 30, 1920. Retting.-Flax, hemp, or other fibrous stems are retted and the epidermis comprising insoluble gum, chlorophyll, dirty resins, &c., rendered gelatinous or viscous, and, in this condition, the material is subjected to strong compression between pressure rollers such as rubber-covered rollers or the like. The gelatinous material is thus squeezed or expressed from the stems and eliminated, leaving fibres of improved colour and held together in ribbon form. The duration of the drying operation is shortened and the subsequent breaking, (crimping), and scutching is simplified, or, owing to the action of the expressing-rollers, may be omitted. Scutching can be effected with the production of a minimum of dust. Specifications 8106/89, 18127/06, and 12162/14 are referred to.

Title: Improvements in and relating to the extraction of finely powdered, oil-containing substances
Inventor: STOLTENBERG HEINRICH
IPC: C11B1/10
Filed: 1956-09-17
Abstract: <PICT:0818045/III/1> Oils are extracted from such finely divided material as rice bran with solvents such as benzine by stirring the material repeatedly in a number of juxtaposed extraction stages by means of sieve-like bucket conveyers, the material being also transported thereby from stage to stage in counterflow to the solvent.  As shown, a suitable apparatus comprises a container 1 into which the material is fed through aperture 2.  The material falls on to guide surface 12, which prevents the material falling directly into buckets 9, and thence to the bottom of chamber 10.  Solvent enters through 4 and leaves through 5.  Material in chamber 10 is stirred by means of the buckets 9 and eventually passes up by means of the buckets, and is discharged into chamber 11 off another guide surface 12. The material passes eventually to the last chamber 13, whence it is discharged from the apparatus through worm 16.  If desired, the chambers may be heated separately or in common, for example by a steam jacket.  Any fine-grained oil-containing material may be so extracted.ALSO:Into cattle fodder there may be incorporated durable rice bran, stated to contain all its carbohydrates, albumins and vitamins, obtained by solvent extraction of oil from the bran, e.g. with benzine, using the method described (see Group III]).

Abstract: 1,077,464. Controlled non-linear inductors. HITACHI SEISAKUSHO KABUSHIKI KAISHA. July 13, 1964 [July 13, 1963], No. 28853/64. Heading H3B. A magnetic amplifier comprises a rectangular loop magnetic core 1 having a control input winding 2 and a gate winding 3 connected in series with an alternating voltage source 5, a load 8 and a switching device 4 operating at a frequency greater than the frequency of source 5. With zero input current in 2, the impedance of gate winding 3 is high and the voltage appearing across load 8, when transistor 4 is switched on by voltage pulses from source 6, is negligible. With a sufficient input current in 2, core 1 is saturated during parts of alternate half-cycles of the current from 5. During the periods in which the transistor conducts with core 1 so saturated the voltage from 5 appears across the load resistor 8. The pulse output so appearing across 8 can be varied from a single pulse, of duration less than a transistor conduction period, in each alternate half cycle of the voltage from 5 to a number corresponding to the number of such conduction periods during such half cycle. Reversal of the direction of the input control current in 2 results in a pulse or pulses in the half cycles of opposite sign (Fig. 4, not shown).
