Title: Improvements in or relating to adaptive memory devices
IPC: G11C11/36
Filed: 1964-12-21
Abstract: 1,083,979. Coherable adaptive memory device. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 21, 1964 [Dec. 19, 1963], No. 51843/64. Heading H1K. [Also in Division G4] An adaptive memory device comprises a first body of coherable particles and a second body of coherable particles arranged in interacting relationship relative to said first body, the impedance of either of said bodies having a tendency to be lowered within limits by the existence of a decohering current in the other of said bodies. A memory device 10 comprises two bodies 13 and 14 each comprising particulate coherable material e.g. Ni, Sn, Al or C, embedded in an epoxy resin or polyvinyl alcohol or enclosed in a casing. As shown in Fig. 4, the impedance of body 14 is lower than that of body 13 and capacitor 31 is not charged. If 31 is connected via 32a to a negative voltage source, it will be charged but when connection is made to 32b the current surge through 14 causes a quantum of decoherence therein thus raising the impedance thereof and causes a corresponding quantum of coherence in body 13 thus decreasing the impedance of 13. The differential voltmeter 33 will now give a reading at A and B a step away from the previous reading. If the capacitor 31 is repeatedly charged and then discharged through 14 a number of stepwise alterations in one direction will be effected. To reverse this voltage trend, the capacitor 31 is discharged through body 13 in a number of steps, each step producing decoherence in 13 and coherence in 14. The device is said to exhibit the phenomenon of transcoherence. It is suggested that during decoherence in one body major intergranular arcing causes coherence breakdown and generates electromagnetic waves which are received in the other body and cause build up of coherence therein.

Abstract: 1439396 Ion exchange HIMSLEY ENG Ltd 12 Nov 1973 [16 Nov 1972 21 Sept 1973] 52362/73 Heading B1J A process for treating a fluid by contact with solid particles comprises continuously introducing untreated fluid into one end of a contacting column having therein a plurality of communicating contacting chambers through which the fluid flows in succession, and continuously removing treated fluid from the other end of the column, a portion of said solid particles being located in each of said contacting chambers and being retained in the contacting chambers by the flow of fluid therethrough, periodically removing solid particles substantially completely from the contacting chamber at the said one end of the column and, commencing with the next chamber in the direction of flow of fluid, causing the solid particles to be transferred progressively and substantially completely from each chamber to the adjacent chamber in the direction opposite to the flow of fluid, said transfer being effected while continuing the flow of untreated fluid into the column and of treated fluid out of the column, and introducing a fresh portion of solid particles into the chamber at said other end of the column. As shown, a column 10 is divided by baffles 11 into chambers A, B, C, D, E. A valve end 16 carries cores 17b etc. adapted to close the apertures in the baffles. In use, pregnant liquor from tank 13 enters the column by valve V1, flowing upwards through resin in each chamber and lifting the valve members 17. The resin is retained in each chamber by the flow of liquid; to move resin from one chamber to the next, e.g. from B to A, part of the liquid may be bypassed via valves V9A and V9B so that the flow through the baffles is no longer sufficient to maintain the resin. A bypass flow greater than the normal flow may be set up by pump P3 in which case there is a compensating downward flow of liquid in the column which transfers the resin more speedily. 12 indicates a backwash chamber and 15 an elution column where desired values are removed from the resin thereby regenerating it.

Abstract: 1377097 Coated glass fibres GENERAL ELECTRIC CO 11 Nov 1971 [21 Dec 1970] 52463/71 Heading B2E [Also in Division C3] Reinforcement glass fibres for moulding resin compositions are individually uniformly coated with a flame-retardant (defined) resin sizing composition. The glass filaments may be of lime-aluminium borosilicate glass, which is relatively soda free. The filaments may be bundled into fibres, and the fibres bundled into yarns, ropes or rovings or woven into mats. Conveniently the filamentous glass is in the form of chopped strands of # inches to 2 inches long. Suitable flame-retardants are plastic or thermosetting resins such as thermoplastic halogenated vinyl polymers such as polyvinylidene chloride or polychlorostyrene, or halogenated epoxy or halogenated polyester resins. The sizing composition may comprise a thermoplastic or thermosetting resin and a flame-retardant additive. Numerous suitable resins for the sizing composition are listed together with suitable flame-retardant additives. In Examples chopped glass rovings lightly sized with dextronized starch are coated with an epoxy resin containing heavily chlorinated diphenyl containing more than two chlorine atoms per phenyl nucleus. In another Example glass fibres containing 1.2% by weight of a thermoplastic styrene-ethylacrylate copolymer sizing material is coated by immersing in a solution in chloroform of chlorinated biphenyl and drying. In Example 3 the sizing composition was a polyester resin containing "Hetron" PRI-30 (Trade Mark) and applied to the glass fibres by dispersion in a solution of 7.5 parts by weight of the sizing composition and 150 parts by weight of chloroform. In Example 4 the resin composition is a poly(o,p-dichlorostyrene).

[Also in Division Dl] Composite yarn or an insulated conductor comprises a centrally disposed core strand in the form of a spun staple or continuous filament yarn or a monofilament or a metal wire and a wrapping component constituted by one or more continuous filaments in the form of a multiplicity of serially connected, axially extending loops arranged so that they progressively advance along the axis of, and helically twist around, the core, many of the loops being contained for at least part of their length within another loop thereby providing a nest of loops which, as a continuous, tight, tubular sheath, completely envelops the core. The wrapping filaments may be of a synthetic polymer, e.g. a polyamide, polyester, polyhydrocarbon, polycarbonate. The core may be elastic, e.g. derived from polyesterurethane such as identified in Specification 1,040,365, or derived from N-alkylated polyamide as identified in Specifications 1,037,474 and 1,060,799. Yarn is produced by passing an extruded continuous filament 37 (or up to, say, 50 thereof) to a rotating body 21 on which it is wound. The body has a peripheral speed sufficient to tension, attenuate and molecularly orient the filaments and a reciprocating movement is imparted to the filament by a traverse mechanism 25 whereby the filament is coiled around the body so as to form a constantly accumulating sleeve 38 comprising overlaid and interconnected helices. As the sleeve is continuously withdrawn from the body so as to impart twist to the coils of filament, a core strand 26 introduced within the sleeve moves along an axial passage in the body and the axis of rotation at a speed less than the peripheral speed of the body and is enveloped by the sleeve serving as a wrapping component. The core strand may be fed through and from the rotating body in the same direction as, or in the opposite direction from, the sleeve movement: in the latter case, the sleeve is everted as it leaves the body and is withdrawn through the axial passage therein.

Title: Electronic flash tube

Filed: 1970-11-05
Abstract: 1328553 Arrangement for controlling a flash tube PHILIPS ELECTRONIC and ASSOCIATED INDUSTRIES Ltd 5 Nov 1970 [8 Nov 1969] 52713/70 Heading G2A A control circuit for a flash tube 4, in which the flash tube is shunted by a circuit comprising a resistor 6, a switching element 7 and a capacitor 8, and wherein the duration of the flash is influenced by a control circuit of the switching element 7 which contains a photo-sensitive element 15, fed from a previously charged main capacitor 3. The capacitor 8 is included so that the main capacitor will not completely discharge after each flash. When taking a photograph, a voltage is applied between terminals 20 and 21 thereby igniting the flash tube 4 and charging a capacitor 14 via primary 5 and secondary 12 windings of a transformer. Light received by the photo-sensitive element 15 after being reflected off the object being photographed decreases its resistance causing a current to flow to a capacitor 18 which triggers switching element 7 when the voltage of the capacitor 18 is high enough. This allows current from the main capacitor 3 to flow through the shunt circuit 6, 7, 8 until the voltage on capacitors 3 and 8 has become substantially equal. Both capacitors 3 and 8 then discharge through flash tube 4, the current from the capacitor 8 going by way of diode 10. When the charge of the two capacitors 3 and 8 has decreased to the minimum operating voltage of the tube 4, the tube 4 is extinguished leaving a residual charge in the main capacitor 3. The controlled switching element can be a quench tube or a thyristor.
