Diorganosiloxane block copolymers containing segments (of e.g. 3-5 siloxane units) grouped into two or more blocks are prepared by (1) reaction of an anionic polymerization initiator MX, wherein M is K or Na and X is H, OH or an alkyl or aryl radical or a carbanionproducing hydrocarbon or a group wherein each Q is an alkyl, alkenyl or aryl group and Q<SP>1</SP> and Q<SP>11</SP> are each as Q or OM, with a cyclic polysiloxane containing units RR<SP>1</SP>SiO wherein each R is an alkyl, alkenyl, aryl or alkaryl group and each R1 is an alkyl or alkenyl group, then (2) reaction of the product in the presence of a proton-free polar solvent with a hexaorganocyclotrisiloxane having units R<SP>11</SP>R<SP>111</SP>SiO wherein each R<SP>11</SP> and R<SP>111</SP> represents an aryl or alkaryl group; (3) optionally repeating step (2) with a further cyclotrisiloxane having units RR<SP>1</SP>SiO or R<SP>11</SP>R<SP>111</SP>SiO; and (4) neutralizing the product with an acid or a triorganochiorosilane, diorganodichlorosilane, or mono- or di-chloroterminated polydiorganosilane, the step (2) being conducted at 0-60‹ C. when M is K and at 40- 120‹ C. when M is Na. The cyclic siloxane of step (1) is, e.g., a trimer, tetramer or pentamer and may be diluted with a proton-free solvent; the cyclotrisiloxane of step (2) is preferably previously diluted with e.g. benzene, toluene or xylene. In Examples 1-5 Me 3 SiOK or Me 3 SiONa or Me 2 Si(ONa) 2  in tetrahydrofuran is mixed with octamethylcyclotetrasiloxane, alone or mixed with tetramethyltetravinylcyclotetrasiloxane, or with hexamethylcyclotrisiloxane; the product is reacted with hexaphenylcyclotrisiloxane dissolved in benzene, and this product is neutralized with glacial acetic acid; in Example 4 a pyridine/benzene solvnet is used throughout and Me 3 SiCl is used for the neutralization.

Abstract: 1,231,318. Transistor logic circuits. VARIAN ASSOCIATES. 6 Aug., 1969 [28 Aug., 1968], No. 39455/69. Heading H3T. [Also in Division G4] A decoder for use in the electrographic recorder described in Specification 1,191,028 which is referred to includes a plurality of "and" gates 3-3, Fig. 2, each comprising two seriesconnected resistors 36, 37 from the junction of which an output is taken to an electrographic writing electrode 21, and a series-connected diode 38 and resistance 39 arranged to shunt the second 37 of the first two resistors. In operation the potential applied to the electrode 21 is high except when two transistor control circuits X 1 , Y 1  are both in their low impedance state whereupon the potential applied to the electrode 21 falls substantially to zero. If the control circuit Y 1  changes to its high impedance state the diode 38 becomes conductive and the output potential rises, and if the control circuit X 1  changes to its high impedance state the output potential rises because of the potential divider action. In a modification and additional diode 56, Fig. 3, is employed, which, because of the stray capacitance 55 between the electrode 21 and earth, retards the subsequent rise in potential of the electrode 21.

Abstract: 1,250,478. Extruding thermoplastics netting. NETLON (P.T.A.) Ltd. 10 Feb., 1969 [23 Feb., 1968], No. 8977/68. Heading B5A. Extruded thermoplastics netting in strip form, Fig. 5, having two sets of strands 6, 7 wherein set 6 is parallel to the edges 12 of the strip, is made by extruding tubular netting from an extrusion head 1, Fig. 2, in which neither set of strands is parallel to the direction of extrusion, and hauling off the netting such that it rotates about a mandrel 9 with the strands of one set following a fixed helical path over the mandrel surface whilst at the same time cutting the tubular netting by means of a knife 13 between a pair of adjacent strands of this set. Extrusion head 1 comprises circumferentially orificed concentric die rings 4, 5. As shown, outer die ring 4 is rotated and inner die ring 5 is held stationary, but preferably, to simplify machine construction, this situation is reversed. The strand set from the stationary die ring follows the helical path over the mandrel, which path is determined by the position of a roller 15 upstream of the haul-off means (not shown). Further rollers 16, 17 and (18), Fig. 3 (not shown), are provided to guide the strip initially into a direction parallel to the direction of extrusion and then through and out of coolant liquid 3. As shown the axis of roller 15 is at 45 degrees to the horizontal, but variation in this angle and position of the roller may be made to vary the width of the resulting strip, see Figs. 8-10 (not reproduced). Knife 13 preferably cuts between two thickened strands 6, Fig. 4 (not shown) to give the strip reinforced edges, Fig. 5. The mesh shape may be square, Fig. 5, rectangular, Fig. 6 (not shown), or parallelogramic. The blade of knife 13 may be partially accommodated within a slot in mandrel 9.

Abstract: 1290782 Cathode-ray storage tubes RCA CORPORATION 8 Jan 1970 [8 Jan 1969] 1014/70 Heading H1D The target of a cathode-ray storage tube comprises a substrate of N<SP>+</SP>, P or P<SP>+</SP> type semiconductor on which are provided storage regions formed of an insulating compound of a semiconductor material. The semi-conductor may be silicon or germanium and the insulating compound the dioxide or nitride. In Fig. 2 the insulation 34 is in the form of a grid with square apertures exposing parts of the surface of the substrate; if the layer 34 is of silicon dioxide it is preferably less than 3 microns thick for ease of fabrication. In modified constructions, Figs. 3 and 4 (not shown), the insulating layer 34 comprises an array of square lands or of longitudinal strips. In a further modification, Fig. 13 (not shown), the exposed squares 32 of the substrate are covered with an oxidation-inhibiting coating of gold, silver, tungsten, molybdenum, platinum, or nickel to a thickness of about 1000 Š.U., preferably by sputtering. In another modification, Fig. 14 (not shown), the exposed squares and part of the surrounding insulation 34 are coated with the same material as the substrate to provide an increased beam landing area. A different construction (Figs. 15 and 16, not shown) employs a continuous insulating layer over the substrate, and a grid-like conductive layer of metal or semi-conductor material is formed over the insulating layer. This conductive layer may extend over the edge of the insulating layer to the substrate (Fig. 15) or it may be electrically independent of the substrate (Fig. 16). Operation.-The substrate 30 is also the signal plate and is initially held at 20V whilst the insulation 34 is scanned to reduce its potential to zero (Fig. 6, not shown). The plate 30 is then raised to 100V, thereby carrying the insulation 34 up to 80V, and the target is scanned by a modulated beam which produces charged areas varying in potential from 80V to 90V (Fig. 8, not shown). The plate 30 is then reduced to 10V, thereby making the charged areas range in potential from -10V to zero, and the target can be scanned to produce a non-destructive read-out, electrons passing to the exposed areas 32 to a variable extent depending on the charges stored on the surrounding insulation 34. Finally the charge pattern can be erased by raising the potential of plate 30 to 20V and scanning the target.
