IPC: A24B5/10
Filed: 1965-11-04
Abstract: 1,154,082. Treating vegetables. UNILEVER Ltd. 2 Nov., 1966 [4 Nov., 1965], No. 46784/65. Headings A2E and A2Q. A process for substantially separating the vascular tissue from the soft tissue of the stems and leaves of green vegetables (e.g. parsley, celery and chervil) comprises partially drying the vegetables, breaking the partially dried material so as to substantially detach the vascular tissue from the soft tissue, and substantially separating the vascular tissue from the soft tissue. "Vascular tissue" means the tough coarse tissues of the principal vessels in the vegetable which has a lignified nature (e.g. xylem and tracheides). "Soft tissues" means the softer, more digestible parts of the vegetables which do not contain vessels or which contain only vessels which have not a lignified nature. The soft tissue may be separated by winnowing or sieving. In the embodiment shown, the vegetable material is conveyed on screen conveyer 1 through drying unit 2 in which air heated by steam heated units 9 is circulated by fans 7, and beneath rotating drum 3, the soft tissue being broken by the abrasive action of the relative movement of drum 3 and conveyer 1, and being sieved through conveyer 1 and the vascular tissue being retained on the conveyer 1. The speed of the drum and conveyer, the pressure on the vegetable material, and the distance of the drum above the conveyer may be varied. The drum 3 may comprise a flexible material and have a variable internal pressure. The drum may be replaced by endless band (21) (Fig. 2, not shown).

Abstract: 1532865 Controlling I C engine fuel injection WISSENSCHAFTLICH-TECHNISCHES ZENTRUM AUTOMOBILBAU KARL-MARX-STADT VEB 11 Nov 1976 [18 Nov 1975] 46962/76 Heading F1B A fuel injection system comprises first and second pulse generators rotating with the crankshaft and the cam-shaft of the engine respectively and electronic switching means responsive to coincidence of the pulses to distribute them to the fuel injection valves associated with each cylinder of the engine. As shown, a crank-shaft driven disc 1 influences sensors 11, 12, 13 to produce pulses which are shaped at 101, 102, 103 and pass to pairs of AND gates 41, 46; 42, 45; 43, 46 respectively. A disc 2 driven by the engine cam-shaft produces a positive and negative pulse each revolution which pass either directly or through inverter 3 to the AND gates. When the pulses coincide the respective AND gate triggers the associated thyristor 51-54 and thus allows an injection pulse which is computed in calculator 7 from sensed operating parameters to pass through to the respective injector valve 61-64 for a period that is determined by the extent of the protrusion on the crank-shaft disc. Preferably the crank-shaft disc sensors produce sawtooth outputs which progressively decrease in amplitude.

Abstract: 1478851 Treating ball clay ENGLISH CLAYS LOVERING POCHIN & CO Ltd 30 Sept 1974 [11 Oct 1973] 47635/73 Heading C1A The properties of a ball clay are improved by suspending the raw ball clay in water to form a suspension of solids content not greater than 55% by weight, subjecting the aqueous suspension thus formed to a beneficiation operation in order to remove undesirable impurities, thickening the aqueous suspension of beneflciated ball clay in an apparatus which is equipped with means for discharging a thickened, solid-containing material to produce a dewatered beneficiated ball clay of solids content at least 50% by weight and drying the dewatered beneficiated ball clay. The starting suspension suitably contains 30 to 55% by weight of the raw ball clay and suitably contains a deflocculating agent, e.g. a water-soluble salt of a polysilicic acid or polyacrylic acid, a water-soluble condensed phosphate or a copolymeric deflocculant as described in Specification 1,414,964. The beneficiation operation may comprise wet sieving, particle size separation by means of gravitional or centrifugal sedimentation, magnetic separation or froth floatation or a combination of two or more of these techniques. The aqueous suspension of beneficiated ball clay may be thickened in a knife discharge clarifier or a mechanical conveyer centrifuge. When the beneficiation operation is performed in the chemically deflocculated state, a flocculant must be added to the suspension before thickening, e.g. dilute mineral acids, water soluble salts which include polyvalent cations and long chain organic flocculants. The dewatered beneficiated ball clay may be extruded, pelletized or shredded before being dried in a rotary, turbo-tray, fluidized bed or apron dryer.

Title: Particle analyzer with real time analysis capability

Filed: 1975-11-28
Abstract: 1497698 Photo-electric particle analyzers W G ROWE 28 Nov 1975 [8 Jan 1975] 49074/75 Heading G1A An apparatus which investigates particles in a sample has an optical system which casts an image of the particles on to an array of photo-detectors, the signals thus produced being digitized, stored and processed. In Fig. 1 the sample is illuminated by a source 14 when in a cell 25, and the transmitted light is imaged on to the detector array 32 by a lens system 30. The sample is supplied by a pump 24 via a valve 23 and flowmeter 22, and it exhausts via density meter 12, valve 11 and flowmeter 10. A cleaning fluid or a dilution fluid may similarly be passed through the cell. The array of detectors comprises a matrix of photo-diodes and capacitors, Fig. 4 (not shown) which are sequentially read out to determine the illumination on each diode. The current pulses produced by reading are digitized (in the simplest case, either a 0 or 1 is formed) and stored at 36 under control of logic unit 37. The logic unit then examines the stored data and generates a tag for each. particle represented by the data; the tags are stored with the data, after which the data associated with each tag is analyzed to find the dimensions and shape of each particle.  The light source may be strobed to freeze the particle motion; for slower motion the diodes may be read out in a rapid sequence. In either case the results of the measurements can be displayed, but it is prefered to display the average of many successive measurements. The control logic passes each measurement to a buffer 38 where it is averaged with the N previous measurements and the result is displayed on CRT 39. Details of unit 37 are given, Fig. 3 (not shown), as is a suitable form of display histogram, Fig. 5 (not shown). The sample turbidity can be found by comparison with light by-passing the sample on guide 42. The light source intensity is increased for turbid samples, or in more extreme cases the sample is automatically diluted. A cleaning fluid is also provided, and is admitted to the sample cell when the image contrast falls below a given level. The effect of bubbles is removed by circuitry which identifies any "particle" having a light centre to its image on the array. The magnification is set by a motor 29 controlling lens system 30. A reticle on the cell provides a standard pattern so that the degree of magnification can be found.

In the particular embodiment, timing pulses are routed to two sets 13A, 13B of Piezo-electric transducers alternately, to produce mechanical pulses in medium 10 which are detected by a Piezo-electric transducer 16. Each timing pulse also starts a free-running counter which is stopped, read-out and reset to zero on a signal from transducer 16. Read-out is into a computer memory 12 the contents of which are reproduced on a cathode ray tube display underneath the medium 10 which is transparent, thus showing the user what he has "drawn". The rows of transducers 13A, 13B are shown perpendicular, to give rectangular Cartesian co-ordinates of the position of transducer 16, but the rows may be non-orthogonal and coversion (no details) to rectangular Cartesian co-ordinates effected.
