Patent GB-1124259-A (GB)
Title: Improvements in and relating to a process for delaminating mica
IPC: C04B14/20
Filed: 1965-11-30
Abstract: Mica is delaminated into flakes by placing it in a liquid medium in which cavitation can be induced, e.g. water, containing non-mica solid particles small enough to be able to delaminate the mica, e.g. calcium carbonate, sodium bi-carbonate, and silica, suspending the mica and non-mica particles in the medium while subjecting the medium to vibrations of such energy as to cause cavitation in the liquid, said cavitation continuing for a period of time sufficient to impel the non-mica particles against the mica in the plane of cleavage in order to delaminate the mica into thin flakes, and thereafter separating the mica flakes from the medium.  The medium may be additionally mechanically agitated during the delamination.  The weight ratio of mica to calcium carbonate is preferably 1 : 1-2 : 1 and the ratio of water to mica is preferably 10 : 1-20 : 1 and the temperature used when water is the medium may be 90-180 DEG  F.  The process is applicable to both synthetic and naturally occurring micas including the group of mineral silicates crystallizing in monoclinic forms and capable of being split into thin sheets and flakes. Examples demonstrate delamination of fluorphlogopite and muscovite micas.

Abstract: 1441425 Builder mechanism SACO-LOWELL CORP 5 Nov 1973 [7 Nov 1972] 51299/ 73 Heading D1D In a yarn twister, a builder drive reciprocating a ring rail is reversed by a proximity switch, the switch and its actuator being mounted for relative movement along arcuate, concentric paths. A ring rail is reciprocated vertically, Fig. 4, by windlass 16 via tape 18. Arm 40, rigid with windlass shaft 16' carries actuator 32, and gears 36, 38 freely rotatable on shaft 16' carry proximity switches 28, 30. The switches control clutches to drive the windlass in opposite directions. To produce wind A, Fig. 6, gear 38 is manually rotated via knob 62, shaft 50 and gear 54 to position switch 30. Switch 28 is positioned by rotating knob 64, shaft 52, gear 55 and gear 36. The switches are locked in position by locking elements 90 locking gears 58, 59. The windlass is then rotated, and actuator 32 rotating with shaft 16' actuates switches 28, 30 and hence the clutches to reverse the windlass. To produce wind B, gear 58 is unlocked and motor 42 oscillates gear 38 to vary the position of switch 30 to produce the "peaks" and "valleys" of the wind. Motor 42 is reversed by two proximity switches adjustably fixed in slot 95 and actuated by actuator 69 oscillating with gear 38. Wind D is produced by adjusting timer 70 to delay motor reversal. To produce wind C, the four switches are suitably positioned, and motor 42 oscillates the gear 38 and, via movable gear 60, the gear 36. To produce wind E, gears 56, 57 are replaced by larger, intermeshing gears to oscillate gears 36, 38 in opposite directions. The proximity switches are magnetically actuable and actuators 32, 69 are magnets.

Abstract: 1377748 Magnetometers MISHIMA KOSAN CO Ltd 9 Nov 1971 [9 Nov 1970 21 Nov 1970] 52093/71 Heading G1N In a magnetic thin film fluxgate magnetometer, an alternating bias current of a value corresponding to the width of the hysteresis loop of the output of the sensor Fig.4, is applied to the film, in addition to the driving alternating current, so that weak magnetic fields Hex of values less than the width of the hysteresis loop can be detected. The film (5) may be of permalloy and may be applied by electro-deposition or winding to a glass tube (6) surrounding a copper wire (4) to which the driving A.C. is connected. The glass tube may be omitted. The film may be laminated. In Fig.1, the film is surrounded by windings 7, 8, winding 8, the pick-up winding, being either in two oppositely wound halves or at right angles to the driving current. A capacitor 12 is connected across winding 8 to form a resonance circuit. The A.C. bias current is applied to terminals 16 and 17 or 18 and 19. 14 and 15 are high value impedances. Alternatively a drive winding (21) and an A.C. bias and pick-up winding (23) may surround a plate-like film Figs.7a, 7b (not shown). The drive winding (21) or the winding (23) may be reversed half-way. In Fig.10, an A.C. driving current from source 30 is amplified at 31 and fed to the magnetic sensing element 32 and reference phase generator 33. The output of the element is phase-detected at 34, integrated at 35 and fed to an indicator 36 and, as negative feedback, to the element 32. The negative feedback may be sufficient to reverse the field being measured, the system oscillating between two states in which the output of the sensing element has O and # phases. Alternatively, a non- oscillating mode of operation may be employed in which feedback is used merely to cancel the sensed magnetic field.

Title: Process and apparatus for separating crystallizable materials from a multi-component system

Abstract: 1507034 Crystallisation process DEJ INTERNATIONAL RESEARCH CO BV 26 Nov 1975 [6 Dec 1974] 52900/74 Heading BIG  A process for separating crystallisable material out of a multi - component liquid system comprises the following steps performed in sequence latchwise: (a) confining a batch of liquid in a heat exchanger, (b) applying cooling to the heat exchanger to crystallise at least part of the crystallisable material and create a substantially coherent matrix of crystals, (c) removing the material formed in step (b) from the heat exchanger, (d) breaking up the material from step (c) into a predetermined size and (e) separating crystallised material from the remainder of the multi - component system. Suitable aparatus, as shown in Fig. 1, for the freeze concentration of e.g. aqueous systems such as coffee extract and fruit juices, comprises a storage vessel (1), a number of shell and tube heat exchangers (3-12) mounted in parallel and connected to a central feed line, below the heat exchangers are an equal number of grinding means for breaking up the columns of ice and concentrate and simultaneously mixing the broken ice with recirculated concentrate and a washing column (13) for separating ice and concentrate. The process is carried out so that at the end of each freeze cycle the pump (2) pumps feed solution into the heat exchanger and so forces the columns of ice crystals and concentrate which have formed in the heat exchanger out of the exchanger, the columns of ice having first been released from the tube walls by briefly applying heat. A new freezing cycle starts when only a small frozen plug (28) remains in each tube (27). The frozen columns are broken up upon leaving the tubes by the knives (30) driven by a motor (33). The mixture of ice and concentrates enters the mixing vessel (32) at regular intervals and is transformed into a slurry for processing by the separating apparatus i.e. a washing column (13).

Abstract: 1280085 Semi-conductor devices SIEMENS AG 9 Nov 1970 [10 Nov 1969] 53167/70 Heading H1K A readily solderable contact is made to a semiconductor body by depositing gold, heating- below the temperature at which oxide complexes form to form a gold-semi-conductor euteotic alloy and then depositing a layer of nickel on the alloy. Typically the gold is electrolessly deposited to a thickness of 0À7 Á and then heated in air for at least 3 minutes above 356‹ C. if the semiconductor is germanium and between 378‹ and 500‹ C. if it is silicon. Nickel is then deposited electrolessly to a thickness of at least 0À8 Á and an overlayer of gold preferably provided. The contact may then be soldered to a nickel plated iron, copper or brass base using lead-tin or leadsilver indium alloy. The detrimental formation of silicon-oxygen complexes which arise in the temperature range 600-500‹ C. is avoided by use of this method.
