Title: Storage circuit using multiple condition semiconductor storage elements
IPC: G11C19/18
Filed: 1972-11-20
Abstract: 1401487 Shift register stage RCA CORPORATION 20 Nov 1972 [22 Nov 1971] 53454/72 Heading H3T To enable a dynamic shift register stage, Fig. 3, to permanently hold the data contained in it when required, a variable threshold F.E.T. T 4  is incorporated which is set to a high or a low threshold condition according to the binary value of the input at 16. When operating dynamically in response to clock signals # 1 , # 2 , the low threshold condition is first set and maintained by voltage levels (at time P1, Fig. 4, not shown) which are +20 at V S1 , V D1  and O V  elsewhere, including # 1 , # 2 . F.E.T.'s T 2  and T 3  apply the + 20 to the gate of T 4  to produce the positive gate bias (V D2 , V S2  being O V ) needed to set the low threshold (V TL , Fig. 1, not shown). Normal dynamic operation then follows (in P2 time), wherein V D1  is -10 V and charges C2 in # 1  time through T 3 , the data at 16 determining whether or not T 1  conducts to discharge C2 to V S1  which is now O V . T 4 , T 5 , T 6  operate similarly when # 2  occurs. In order to effect static storage (P3 time) at T 4  of the data at 16, V D1  is taken to -20 V, and T 1  conducts or not according to the data so that C2 is either earthed through T 1  to V S1  (still O V ) or charged to - 20 V by V D1  through T 2 , T 3  in # 1  time. Since V D2 , V S2  are O V  the gate of T 4  is thus biased either negatively enough to change to the high threshold (V TH ), or else by only a small amount which does not alter the threshold from the low state. To reset to dynamic operation (P4 time), V D1 , V S1  and 91 go to -10 V, so that T 4  gate and C2 discharge towards -10 V and reach a value of about -6 V due to threshold drops. As this is intermediate the two thresholds (V TH , V TL ), T 4  will conduct only if the low threshold was stored, and in # 2  time the output C1a will accordingly charge to - 10 V (V D2 ) or not. Having extracted this data, the low threshold is reset by the same steps as before (P1 time) to permit further dynamic operation. T 4  is a MNOS transistor which permits the two threshold conditions to be maintained, and information thus statically stored, for very long periods.

Abstract: 1329598 Matt surfaced polystyrene film OJI YUKA GOSEISHI KENKYUJO KK 27 Nov 1970 [28 Nov 1969 12 March 1970 26 Aug 1970] 56462/70 Heading B5B Drawn polystyrene film containing elastomeric particles of size 0À1-10 Á (e.g. of polybutadiene or poly-(butadiene - styrene) and which may be grafted on to the polystyrenes) is given a matt surface by treatment with a liquid having solvent action on the polystyrene and swelling action on the particles, followed by positively stopping the action of the liquid. Stopping may be with a non-solvent (e.g. methanol) at least partially miscible with the liquid or by cooling the film below the temperature at which the liquid affects it. Liquids exemplified are heptane, hexane and octane and may also contain chlorobenzene, toluene or benzene to modify their efficacy. Cooling may be effected with polished, cooled squeeze-rollers. The liquid may be floated on water and the film passed through the floating layer before cooling. The product of transverse and longitudinal elongations in the drawn film should be at least 6, but is not so restricted provided treatment is between 30 C. and the deformation temperature of the film, cooling below 40 C. is used to stop the solvent/swelling action, and the liquid satisfies a given equation relating to its solvent power. In examples is used an ABS resin or high-impact polystyrene containing butadiene and optionally blended with high-impact polyethylene.

Filed: 1970-11-30
Abstract: 1318927 Expanding and guiding tubular film ESSO RESEARCH & ENG CO 30 Nov 1970 [22 Dec 1969] 56711/70 Heading B5B In a process for extruding a tubular film downwardly, expanding it, and passing it over a cooling mandrel before collection, the film is externally guided during the expansion step by a plurality of concentric annular pressure zones which exhibit a decreasing pressure gradient in the downward direction. The zones are provided by means of a series of annular orifices arranged in echelon. As described, a support plate 42 carries a fixed ring 24, and this supports three movable rings 22, 26, 28, which carry annular plates 78, 80, 82 respectively. The movable rings are pressure-sealed by 0-rings 110 and are kept from binding against each other by spring-biased studs 100. Ring 24 has two camtracks 90, 92 which run diagonally round a portion of the circumference. Followers 94, 96 and 98 engage in these tracks such that rotation of any movable ring by a handle (e.g. handle 8 as shown for ring 22) causes vertical movement of that ring. Each handle may be fixed in position after adjustment, as at 118, 116. Air is fed to the rings via annulus 76. The edges of the plates 78, 80, 82 preferably lie on a straight line in use, but may lie on an arc whose sagitta does not exceed 7À5% of the length of the chord subtending the arc. In one embodiment (Fig. 2, not shown) the mandrel includes a hollow, watercooled, film-contacting annulus, and is surrounded by a cooling ring which presses the film against the annulus by pressure derived from direct contact of the outside of the film with cooling water.

Abstract: 1432497 Fire-hose nozzles J P R MICHARD 7 Dec 1973 [11 Jan 1973] 56950/73 Heading B2F [Also in Divisions A5 and A6] A nozzle, of brass or a light alloy, adapted for attachment to a fire-resistant hose, comprises an ogival-shaped hollow body 10 which is symmetrical about a longitudinal axis XX' and includes a supply duct 12 extending in the direction of fluid inflow and connected to conduits 13 opening into orifices 14 at the rear exterior of the body where they diverge rearwardly away from the longitudinal axis by not more than 5‹, and propel the nozzle, and to two sets of lateral conduits, those 17 of one being obliquely disposed with respect to said axis and those 16 of the other, being radially disposed, extending towards the lateral exterior of the body, and having diameters less than those of conduits 13. Communicating with these orifices are longitudinal partitioning cells 15 which open out from the duct 12. The nozzle for use particularly with water for fighting a fire in a plastics material or a stored combustible liquid, causes the majority of fluid to be deflected in the opposite direction to fluid flow into the hose through conduit 13, the remainder of the fluid being sprayed from orifices 16, 17. Fluid sprayed from the obliquely directed orifices 17 towards the rear of the nozzle assists in the self propulsion and self support of the nozzle, whereas fluid sprayed from orifices 16 establishes a fluid screen.

Abstract: 1,236,873. Fluidic devices. INSTITUT AVTOMATIKI I TELEMEKHANIKI (TEKHNICHESKOI KIBERNETIKI). 25 Nov., 1969, No. 57534/69. Heading G4P. [Also in Division G3] A pure fluid element comprises a turbulence amplifier having aligned input and output ducts 1, 3, control ducts 2, 2<SP>1</SP>, and an additional control duct 4 aligned with an additional output duct 5. In Fig. 7a fluid from duct 4 can exit at duct 5 only when the jet of fluid from input 1 is rendered turbulent by a control input at duct 2. The device therefore acts as an AND gate, Y = A.B. Fig. 8a shows the element as an OR/NOR gate, Y=X=A+B. In Fig. 9a an input at an extra control input 6 prevents fluid from duct 4 reaching duct 5, the logic function performed therefore being Y=A.B. Fig. 10a shows a bi-stable element. When an input is applied to duct 2 the jet from 1 is rendered turbulent so that the jet from 4 can pass to duct 5. Consequently an output appears at 16. Additionally fluid is fed back to 2<SP>1</SP> to maintain the jet turbulent. If now an input is applied to input 6 no fluid reaches duct 5, so that the output at 16 ceases, there is no longer a feed-back signal, and jet 1 returns to laminar flow. Input 6 may alternatively act on the fluid issuing from 2<SP>1</SP>. Fig. 11 shows a bi-stable arrangement comprising turbulence amplifiers 8, 9 and having a single input 20. Turbulence amplifier 22 supplies a constant pressure to input 20 except when a pulse is applied at 25. This pulse renders the jet from 1<SP>11</SP> turbulent so that the input to 20 ceases. After a time determined by delay 24 the pulse appears at 23 so that the jet from 1<SP>11</SP> becomes laminar and input at 20 recommences. Suppose the flow in amplifier 9 is laminar and in 8 is turbulent as indicated, giving an output 1, 0 at 18, 19. When the input at 20 ceases the fluid from 4 passes to 5 and thence to 211, rendering 9 turbulent. Since the output of 9 is now zero there is no control input at 2<SP>1</SP> and, the input at 20 having now recommenced, 8 becomes laminar. The output at 18, 19 is now 0, 1. Amplifier 9 is maintained turbulent via 2<SP>111</SP>. When input 20 again ceases the fluid flow from 4 is sufficient to prevent the fluid from 1 reaching outlet duct 3, unlike the other embodiments referred to above. Consequently output 19 falls to zero and 9 becomes laminar again, giving an output 1. The bi-stable arrangement may be reset to a state 1, 0 on 18, 19 by a pulse at 17.
