Abstract: 1401307 Flocculating solids NALCO CHEMICAL CO 12 Sept 1972 [22 Nov 1971 23 Nov 1971 2 Feb 1972] 42342/72 Heading C1C A method of thickening or dewatering solids in aqueous wastes (e.g. sewage, coal mining slurry or pulp mill sludge) comprises adding to the waste an aqueous solution of a water-soluble addition polymer prepared by the inverse emulsion technique and separating the resultant flocculated solids, e.g. by settling or vacuum filtering. The polymeric solution is prepared by (a) forming a water-in-oil emulsion from a water phase containing one or more ethylenically unsaturated monomers, an inert hydrophobic liquid and an emulsifying agent (b) polymerizing the monomer(s) to produce a latex, the polymerization being initiated by free radicals produced from free-radical yielding catalysts at elevated temperature, or by high energy radiation or U.V. radiation and (c) producing the polymeric solution from the polymer-containing emulsion, e.g. by using water together with cationic, anionic or non- ionic surfactants (many listed), agitation, heat, pH shift and/or electric fields. The preferred polymers are homopolymers of acrylamide, acrylic acid and dimethylaminoethyl methacrylate and copolymers of acrylic acid or acrylamide with sodium acrylate, dimethylaminoethyl methacrylate or dimethyl sulphate quaternary salt of the last mentioned compound. The hydrophic solvent may comprise one or more hydrocarbons or substituted hydrocarbons, e.g. benzene, toluene, xylene, mineral oils, kerosenes, naphthas and petrolatums. The emulsifier may be hexadecyl sodium phthalate, sorbitan monooleate or monostearate, cetyl or stearyl sodium phthalate or metal soaps. The free radical yielding initiator may be benzoyl peroxide, lauroyl peroxide, 2,2<SP>1</SP> azobies (isobutyronitrile) or potassium persulphate.

Title: A data store
Inventor: PROUDMAN ANTONY
IPC: H03K3/286
Filed: 1965-10-07
Abstract: 1,119,357. Transistor matrix stores. INTERNATIONAL BUSINESS MACHINES CORP. 7 Oct., 1965, No. 42540/65. Heading G4C. [Also in Division H3] Binary storage elements in a matrix store comprise two cross coupled transistors. If the read-out pulse is applied to the word line of the element shown in Fig. 11 it passes through a transistor T2 to the bit line only when transistor T2 of a bi-stable circuit T1, T2 is conducting. Non-destructive read out is thus achieved. Similarly it would pass to a bit line connected to T1 only if T1 is conducting. The circuit may be set to one or other states by pulses applied to the appropriate one of the " write zero " or " write one " terminals or alternatively it may be set by applying a small positive or negative pulse to the bit line, according to whether a zero or one is to be recorded, and lowering the potential of the word line so that setting is effected when the word line is returned to its operating potential. The circuit may be re-arranged so that the bit line is connected to one collector lead and the word line is connected to the emitters in common (Fig. 4, not shown). Alternatively a Schmidt trigger may be used with the word line connected to the collectors and the bit line to the common emitter resistor, one of the bases being connected to earth so that an interrogate pulse on the word line will pass through the other transistor but not through the earthed base transistor (Fig. 5, not shown). Information can be transferred from one memory plane to another through output transistors connected as illustrated in Fig. 9 (not shown). Logic operations may be effected in transferring information from one element in a plane to another (Fig. 6, not shown). To transfer the complement from one element A to another B a half current negative bias pulse is applied to a bit line common to the elements and an interrogate pulse to the word line of A. Word line B is taken to earth potential or below and is returned before the interrogate and bias signals are removed. To transfer the true signal, negative interrogate and positive bias current is used. The logic operation A.B may be transferred to B by interrogating A with a 5 volts signal and applying a conditional reset signal of 0À9 volt to word line B. It is explained that with the normal word line potential of + 1À5 volts and T2 conducting the change over is determined by the point at which T2 is unable to hold off T1 but with the word line potential at +0À9 volt the change over is determined by the point at which T2 is unable to remain on because of reduction of base current. The logic A.B is transferred to B by interrogating A with a negative wave and applying a positive bias to the bit line. Appropriate wave forms are illustrated in Figs. 7 and 8 (not shown). An interrogate signal can also be applied to a bit line and the state detected by sense amplifiers in the word line and this is useful for detecting miss-matches in an associative store.

Abstract: 439,733. Aircraft gun mountings; sights. PRECISION MODERNE, 162, Rue St. Charles, Paris. March 11, 1935, No. 7592. Convention date, March 10, 1934. [Classes 92 (i) and 92 (ii)] An aircraft gun or the like mounted on trunnions and elevated by toothed gearing is provided with further toothed gearing coupled to the elevating gear for automatically moving the elevating trunnion backwards during elevation and forwards during depression of the gun. As shown in Figs. 1 and 2, the trunnions 2, 2<1> of the gun 1 pass through slots 3, 3<1> in the cheeks 4, 41 of the cradle, and are mounted in blocks 5, 5<1> slidably fitted in these cheeks. A casing 7 forms part of the block 5, and on it is mounted one end of a worm shaft 10 threaded through a nut 12 on the cradle and mounted at its other end in a bearing 11 also on the cradle. This end of the worm shaft is coupled by gearing 18, 17, 15, 14 to a hand wheel 13 on the cradle, and the other end is in mesh with a toothed wheel 8 on the trunnion 2. Thus rotation of the hand wheel elevates or depresses the gun and simultaneously moves the trunnions backwards or forwards. In a modification, the toothed wheel 8 meshes with a fixed rack and the trunnion moved backwards or forwards by a screw-and-nut device operated by the hand wheel. In another modification, the rack is in the form of an arc, and instead of the slots 3, a rocking-arm supports the trunnions which are operated by a worm gear. As shown in Fig. 7, the sight 37 may be mounted on the gun 1 by parallel links 40, 41 and connected by a link 38 to the cradle 4 so as to maintain a more convenient position for the eye of the gunner.
