Title: Improvements in and relating to Storage Cells
IPC: G11C11/41
Filed: 1966-12-02
Abstract: 1,160,098. Associative stores. INTERNATIONAL BUSINESS MACHINES CORP. 2 Dec., 1966 [17 Dec., 1965], No. 53968/66. Heading G4C. [Also in Division H3] An associative store uses bi-stable circuits of the type in which one or other of two transistors is quiescent according to the state of the circuit and in which each collector is connected to the opposite base through a path which does not include any series impedance elements, setting being effected by applying concurrently one signal to both transistors and another to one. Thus, setting of the circuit shown is effected by applying a positive pulse to the emitters from a "bias and signal " source 50 so as to reduce the current in the conducting transistor to half and concurrently applying a positive pulse to one collector from one or other of the bias and signal sources 38, 42. The conducting transistor is not normally saturated and the reduction of the current makes the circuit more sensitive to the setting pulses applied to the collectors. Non-destructive send-out may be effected by applying a pulse from source 50 to a word line. This reduces the current in the conducting transistor only and the state is accordingly sensed by the sense amplifiers 40, 44. Alternatively, non-destructive send-out may be effected by applying a positive pulse to one collector line from one of the signal sources 38, 42. No increase in current occurs in the conducting transistor but the other, acting as an emitter folower, passes a current to the word line which is detected by sense amplifier and latch 52, 54. The word line may be connected to the sense amplifier via emitter followers in parallel with other similar circuits (Fig. 2, not shown). Fig. 3 shows four elements of an associative store using the bi-stable elements. Pulses are applied similtaneously to one of the 0 and 1 lines 280, 281 and one of the 0 and 1 lines 272, 273 according to the word to be recognized and no output is produced in the sense line where the word matches. Writing into an element is effected by applying simultaneous pulses to a word drive row and one or other of the 0 and 1 column lines. Simultaneous writing into one element and reading from another may be effected. Selected words may be tagged with the same marker bit by simultaneously sensitizing all the words to be tagged and pulsing the appropriate column lines.

Abstract: 1,241,190. Evaporators; separation of salts from brine. J. B. WARD, C. B. LAKE, G. HENDERSON, F. V. LOCKMAN and M. T. RIBACK. 19 Nov., 1968, No. 54882/68. Heading BIB. Solids are separated from solution in a liquid by evaporating liquid from the solution under atmospheric pressure until a substantial amount of the dissolved solid is precipitated, and then continuing the evaporation under reduced pressure in a flashing zone wherein further precipitation of solids takes place. water is evaporated from brine, e.g. sea water, by passing it through line 16 (Fig. 3) to the upward extensions 38a of the heat-transfer walls 26a (e.g. aluminium sheets) of a vapourcompression evaporator which is provided, in the heating chambers 24a with verticallyspaced, sloping condensate-collectors 42a. The evaporation is carried out at atmospheric pressure. The sea water flows down walls 26a as films 35a, the velocity of the films, at the level where heat-transfer commences, being at least 14 feet/second. The total height of each wall 26a and its extension 38a is preferably about 22 feet. The water-vapour, evolved from the films, are withdrawn from chambers 18a through line 19a into compressor 22a. A small amount of water is injected into the compressed vapour in desuperheater 23a, and the vapour is then passed through headers 41a into chambers 24a where the compressed steam condenses. The condensate flows down walls 26a as films, but these are prevented from becoming thicker than about 0.005 inches by collectors 42a. The condensate is withdrawn from the evaporator through line 28. Some of the brine, withdrawn through lines 44a, is recycled to feed-line 16, and the remainder is passed to a second evaporator of a series of three such vapourcompression evaporators 17a .. 17c (Fig. 1). The brine withdrawn from evaporator 17c is so concentrated that a substantial amount of the calcium sulphate has been precipitated. This brine is passed through filter 46, and the filtrate is submitted to further evaporation in three flash chambers 47a .. 47c maintained under progressively increasing vacua. Steam is withdrawn from the flash chambers through lines 53a .. 53c. The brine slurry from the last flash chamber is passed to filter 56 from which the calcium sulphate cake is withdrawn to tank 51, where it is stirred with condensate water, and then separated, and washed, on filter 63. The filtrate from filter 56 passes to evaporative-crystallizer 59, which is maintained under vacuum and at a temperature of about 130‹F., wherein small crystals of sodium chloride are formed. The slurry is passed to evaporative-crystallizer 69, at a temperature of 145‹F., where the NaCl crystals grow. The slurry then passes to evaporative-crystallizer 72 at 130‹F., and finally to centrifugal separator 74 in which the NaCI crystals are separated from the concentrated liquor.

The other end 114 of the pull-strip 100 is engageable with a predetermined part of the film-strip 40 so that the filmstrip 40 engages the pull-strip 100 after exposure when the film-strip 40 is advanced along a predetermined path, thereby stripping the tear-tab 96 from the container 88. In the embodiment of Fig. 1, the film-strip 40 travels initially from supply spool 26 around rollers 41, 42, past exposure opening 46 and on to takeup spool 28 via roller 48. When supply spool 26 is empty, Fig. 1, the specially-shaped end part 114 of pull-strip 100 engages in a suitably shaped aperture in the filmstrip 40 so that, as re-winding starts, the pull-strip is also wound on to spool 26 and pulls the tear-tab 96 away from the container 88. The processing liquid enters chamber 90 and is applied to the filmstrip by nozzle 92. A knife-edge portion 118 may be provided as shown to sever the pull-strip 100 from the tear-tab 96 which is accomodated in a passage 119. Aperture 46 and prism 50 are used for projection.

Abstract: 1,173,583. Luminescent screens. MATSUSHITA ELECTRONICS CORP. 20 Dec., 1966 [28 Dec., 1965], No. 57009/66. Heading C4S. A method for the recovery of rare earth fluorescent substances from slurries obtained in the manufacture of colour c.r.t.s., in which the slurries comprise rare earth fluorescent substances (e.g. yttrium and/or gadolinium oxide, and yttrium vanadate with europium actviator), comprises separating the solids from the slurry (by filtering or centrifugal separation for instance), adding nitric acid to form a rare earth nitrate solution and adding oxalic acid solution to precipitate rare earth oxalates. The process, applicable particularly to slurries left intact for more than one hour, reduces the Cr content to 0À01% by wt. or less (e.g. 0À005% and 0À0005%), thereby reducing depression of the red colour brightness after baking due to the killer effect and the yellow body colour of the phosphor and subsequent excess U.V. absorption during screen manufacture. Other impurities instanced are V, Si, Al, Cd, Zn, Mg and the slurry may also contain ZnS and ZnCdS phosphors for example. The nitric acid may be diluted with water in amount 2000 to 5000 ml/100 gm. of phosphor and heated to 80 to 100 C. The oxalic acid may be similarly heated and added in amount 1.5 to 2 times the amount for precipitating the rare earths as oxalates. Heating to 800 C. effects conversion to the oxide. Reference is also made to rinsing with 0À1 litres of water/grm. of fluorescent substances, slurries left intact for less than one hour.
