Title: Improvements relating to binary adders.
Inventor: HARKIN FREDERICK MICHAEL
IPC: G06F7/50
Filed: 1966-09-02
Abstract: 1,182,120. Binary adders. INTERNATIONAL COMPUTERS Ltd. 4 Sept., 1967 [2 Sept., 1966]. No. 39259/66. Heading G4A. Each stage of a binary adder arrangement comprising a series of stages has carry inputs from the immediately preceding stage and at least one other stage, said other stage or stages in the case of an even stage in the series being odd, and vice versa. In each stage of a binary adder (Fig. 1), a sum signal S on output line 24 and its complement S on output line 30 are produced from digit signals X and Y, carry-in signal C and their complements #X, #Y and #C by a circuit consisting of AND-gates 10, 12, 18 and 20, inverters 16 and 28 and NOR-gates 14, 22. Carry signals are generated by a circuit (Fig. 2) consisting of two AND-gates (40 and 42 or 46 and 48) and a NOR-gate (44 or 50), the input signals X, Y and C being in true and inverted form in alternate stages and the signal P being the output of the NOR-gate 14 of the corresponding summing stage (Fig. 1). For speeding up the carry propagation (Fig. 3, not shown), each carry generating stage has further AND-gates with respective carry inputs from the three immediately preceding alternate stages (i.e. stage n has inputs from stages n-1, n-3 and n-3) as well as P inputs from 5 adjacent stages (Pn-4 to Pn). The adder is suitable for construction by integrated circuit techniques.
Patent GB-1045442-A (GB)
Title: Production of bipyridyls
Inventor: GREEN MAURICE BERKELEY
IPC: C07D213/22
Filed: 1964-09-28
Abstract: A process for preparing bipyridyls comprises the oxidation of a pyridine/magnesium interaction product with oxygen or an oxygen-containing gas, wherein the oxidation is con. ducted at or below 35 DEG  C.  The Mg/pyridine interaction product is made, for example, by heating Mg metal and pyridine above 80 DEG  C. in the presence of a free radical initiator (see Specification 956,854), such as an alkali metal or a halogen.  Pyridinium salts may also be used as initiators as described in Specification 1,016,547. The interaction product may be used pure or in the crude state from its preparation in excess of pyridine.  This excess may be advantageously removed by distillation, preferably after the addition of an inert solvent such as a hydrocarbon or an ether. The solvent should thus have a b.p. in excess of that of pyridine, or should form an azeotrope with it.  The oxidation is conveniently done by means of air.  The gas is bubbled through the interaction product with concomitant vigorous agitation.  Reaction time is adequately 3-4 hours when the rate of oxygen input is such that substantially all of it is absorbed.  The product is recovered by conventional means, such as fractional distillation, acid extraction, crystallization &c.

A process for the manufacture of articles from elements of a heat weldable cellular material comprises completely expanding the elements and then welding them together by heating to the softening temperature of the material whilst they are kept in a state of compression the compression originating outside the elements. Compression may be carried out in a perforated mould having a lid slidable in piston fashion. Alternatively compression may be obtained (a) by locating in a mould a vessel of variable volume, into which fluid under pressure may be introduced; (b) by injecting the cellular elements under pressure into a closed mould; (c) by passing the elements between calendering rolls; (d) by the worm of an extruder; (e) between a moving piston and a fixed closing device, retractable on completion of the process to allow ejection of the article. Compression may also take place between a moving piston and the material shaped by the previous piston stroke to produce a continuous product. The heating may be by any conventional means, e.g. steam, infra-red rays, or high frequency heating.
