Title: Improvements in or relating to ion-exchange processes
Inventor: DAVISON JACK
IPC: B01J47/10
Filed: 1959-10-12
Abstract: In a method of eluting metal ions from an ion-exchange material, the material is placed in a bath of an eluant and the eluted ions are continuously or periodically removed from the eluant as the elution proceeds.  Preferably the material is agitated in the eluant.  The eluted ions may be removed by electrolysis, e.g. the ions may be aurocyanide anions, the eluant may be a thiocyanate solution, and gold may be deposited electrolytically on a lead cathode.  The eluted ions may be extracted with a solvent immiscible with the eluant, e.g. uranyl nitrate obtained by eluting uranium ions with a nitrate solution may be extracted with ethers or esters.  The ions may be removed by adsorption, e.g. gold ions may be adsorbed by activated carbon. The ions may be precipitated, e.g. copper ions may be precipitated from an ammoium thiocyanate eluant with sodium sulphide. In examples, anion-exchange resins loaded with anionic aurocyanide complex resins loaded with anionic aurocyanide complex are electrolysed in baths of ammonium thiocyanate using carbon anodes and lead cathodes on which gold is deposited; in one instance the ion-exchange resin is loaded with copper, nickel, zinc and iron ions as well as gold ions, and the copper and nickel are eluted first with sodium cyanide.  Specification 901,573 is referred to.ALSO:In a method of eluting metal ions from an ion-exchange material the material is placed in a bath of an eluant and the eluted ions are continuously or periodically removed from the eluant as the elution proceeds.

Abstract: 1537114 Non-volatile semi-conductor memory TOKYO SHIBAURA ELECTRIC CO Ltd 25 Aug 1976 [29 Aug 1975 (2) 25 Dec 1975] 35381/76 Heading H3T A memory comprises a plurality of memory cells, each cell having a power supply terminal, a volatile cell constituted by at least a pair of FETs 1, 2, with N (where N is greater than one) variable threshold FETs, M11-M1N, each connected between the power supply and one of the outputs of the volatile cell and N other variable threshold FETs, M21-M2N, connected likewise to the other output and the gates of these two sets connected to form N pairs each pair forming a non-volatile memory cell. The memory has digit lines D 1 , D 2  coupled to the memory cells and at least one memory selection line W selectively energized to select at least one memory cell and to permit data transfer to and from the volatile cell from the digit line. To transfer data from the volatile cell to a non-volatile cell, a positive pulse applied to a gate control line, MG2, say, puts both MNOSFETs 12, 22 in the high threshold state to erase any data stored in the respective cell M2, A subsequent negative pulse of, say, -30 V. on MG2 reads data into the cell as follows, one output of the volatile cell 1, 2 is at -15 V., the other at zero volts and so there will be 15 volts across one MNOSFET and 30 volts across the other, this last changes its threshold thereby storing non-volatilely the output Q or Q which was at 0 V. To subsequently read-out from the non-volatile cell M2 into the volatile cell the control line MGS is taken high and that on MGD low, this turns off FETs 3 and 4 and turns FET 7 on, thereby putting both Q and Q at -1À5 volt, i.e. lower than Vss by the threshold of 1, 2. Next a read-out voltage of -5 V. is applied to MG2 for the desired cell and MGD returned to a high level to turn FET 7 off. The potentials at Q, Q are now determined by the MNOSFETs 12, 22 and when subsequently MGS is taken low and FETs 3, 4 conduct then this state is maintained by the conduction of one of FET 1, 2.

[Also in Division G1] An arrangement for controlling a vehicle lighting system includes a number of detector devices to energize or de-energize relays controlling the switching of the vehicle lamps and a device which discriminates between the stopping and running of the car, to effect further control of the lighting. In an example of the latter (stopping detector) device (Fig. 12, not shown), when the car is running, the switch 2 is arranged to oscillate continuously between two fixed contacts 2c, 2f to produce alternate charging and discharging of capacitors 37 and 38 to render transistor 41 continuously conducting and 43 non-conducting thus de-energizing a relay connected across output 35. When the switching action of switch 2 is stopped and the switch engages either of the fixed contacts, the transistor 43 is rendered conductive and the relay is energized. Alternatively, in an arrangement of the stopping device (Fig. 10, not shown) in which the relay is energized when the switch 2 is changing, a diode pump controls the transistor switch. An example of a photo-conductor circuit (Fig. 14, not shown) includes a photo-conductor 53, whose resistance increases as the intensity of the measured light decreases, so that the transistor is rendered conducting and the relay 52 energized. The fraction of the feedback voltage to transistor 54 is determined by the variable resistor 49. When this voltage is zero, the relay 52 has an amplifier characteristic (Fig. 15, not shown) but a switching characteristic is obtained when the fractional voltage is increased, the hysteresis width between build-up and decay increasing also. The diode 51 protects the transistor against the back e.m.f. of the relay 52. In an alternative circuit (Fig. 13, not shown) positive feedback is provided through a fixed resistor and the photoconductor is connected to earth through a variable resistor for adjusting the sensitivity. A further modification of a photo-conductor circuit (Fig. 16, not shown) has an amplifier transistor 58 which, as the light intensity decreases, making transistor 57 conducting, saturates to energize a relay across output 35. In an alternative circuit (Fig. 17, not shown) decrease in intensity causes de-energization of the relay. Examples of a combined arrangement of stopping and photb-conductor devices are described (Figs. 18-20, not shown).

Abstract: 367,474. Photographic processes. ELEKTRISCHE GLUHLAMPENFABRIK WATT AKT.-GES., 134, Heiligenstadterstrasse, Vienna. Nov. 26, 1930, No. 35647. Convention date, Feb. 19. [Class 98 (ii).] A method of obtaining from electric incandescent multifilament lamps an illumination which in comparison with the normal emission, is highly intensified in strength and actinic radiation for photographic processes, comprises materially overloading a filament by cutting out a resistance formed bv one or more other filaments in series with it in the lamp. The filaments may be arranged so that they can be connected either in series or in parallel, in known manner, the filament resistances being such that they are overloaded materially when put in parallel, and loaded normally, or underloaded, when in series. To prevent the shortening of the life of the lamp, the overloading of the filament is employed only for the short periods during which the photographs are taken, the lamp being loaded normally, or underloaded during the preparation or setting of the picture. In a preferable arrangement the lamp has two filaments which can be connected alternatively in series or parallel. Specification 359,766, [Group XI], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the separate filaments may be arranged in various positions relatively to the reflector of the lamp, so that the radiated light can be reflected from different angles. This subject-matter does not appear in the Specification as accepted.
