Abstract: 1,234,395. Continuous preparation of polymer dispersions. IMPERIAL CHEMICAL INDUSTRIES Ltd. 20 June, 1968 [30 June, 1967], No. 30353/67. Headings C3G and C3P. A continuous process for preparing stabilized dispersions of polymer in organic liquid, which does not dissolve the dispersed polymer but which does dissolve the monomer from which the polymer is derived, comprises feeding ethylenically unsaturated monomer, dispersion stabilizer and organic liquid into a reaction vessel, whose working capacity occupied by the dispersion is of greater height than average width, and which contains a dispersion of the desired polymer in the desired organic liquid, the monomer being fed diffusely (i.e. the monomer feed is rapidly diluted by the dispersion in the region of the point of addition so as to prevent a localized high concentration of monomer) into the uppermost portion of the dispersion, and a corresponding amount of polymer dispersion being drawn off at the bottom of the vessel, while avoiding mixing of the upper and lower portions of the contents of the vessel. A diffuse feed of monomer is suitably effected by introducing the monomer in one or more thin streams or as a spray. The controlled manner of feeding enables a density gradient to be established, extending from the upper part of the dispersion to the lower part. In order to avoid turbulence when the contents are stirred to prevent sedimentation, the reaction vessel preferably has a circular cross-section, being generally cylindrical or conical in shape. Preferably, the height of the working capacity in the vessel is at least twice the average width. The process is particularly suitable for forming dispersed polymers of esters and nitriles of acrylic or methacrylic acid, and of vinyl esters. The following monomers are used in illustrated preparations (a) methyl methacrylate optionally with a minor proportion of other monomers, e.g. (meth)acrylate esters, (meth)acrylonitrile, butoxymethyl acrylamide, (meth)acrylic acid, itaconic acid, citraconic acid, maleic acid or anhydride, vinyl sulphonic acid and vinylidene chloride, (b) vinyl acetate optionally with vinyl propionate, (c) vinyl chloride, (d) acrylonitrile with vinyl acetate, (e) maleic anhydride with styrene or olefins (unspecified), and (f) methyl methacrylate in the presence of preformed polyethyl acrylate (seed polymer); the preparations being effected in aliphatic hydrocarbons as organic liquid, and the stabilizer being (i) methyl methacrylate-methacrylic acid copolymer esterified with 12-hydroxy stearic acid selfester, (ii) lauryl methacrylate-glycidyl methacrylate copolymer esterified with methacrylic acid or (iii) lauryl methacrylate-methacrylic acid copolymer reacted with glycidyl methacrylate; primary octyl mercaptan is generally used in these illustrations as a chain transfer agent and the catalyst is azodiisobutyronitrile, a peroxydicarbonate or benzoyl peroxide.

Abstract: 1,250,523. Pulse circuits; transistor pulse circuits. PHYSICS INTERNATIONAL CO. 27 Sept., 1968 [27 Sept., 1967], No. 46109/68. Headings H3P and H3T. [Also in Divisions F1 and G3] A piezo-electric transducer 12, (also Fig. 1A, not shown) is periodically energized by sequential operation of a first switch 20 connecting the transducer through a charge-controlling element 22 to a voltage source 14 and a second switch 32 shorting it out. The transducer may operate a fuel injection valve for an I.C. engine. The switches may be transistors 20, 32, each having an associated adjustable inductor 22, 36 for varying the charging and discharging rate respectively of the transducer, and each being operated by a trigger circuit 28. Spark-gaps 104, 96 (Fig. 2, not shown) may be used. A second pair of transistors 24, 34 may be provided to apply an opposite voltage to the transducer. In other embodiments, the first switch (96, Fig. 2, not shown) is operated by a transformer 102 receiving a trigger pulse from a pickup (101) sensing rotation of a magnet (99) on a rotating part (100) of an I.C. engine, and the second switch (104) is operated by a second transformer (111) connected to a second pickup (108); the discharge inductor (106) may be replaced (Fig. 3A, not shown) by the primary (141p) of a spark plug driving transformer. In an alternative embodiment, (Fig. 4, not shown) the first switch is a transistor (152) which is operated by a rotation sensitive pickup (156) as before and which energizes the field winding (158) of an alternator (142) whose conductive rotor (144) is driven by the engine and whose stator winching (150) produces a pulse as a pole 146a or 146b of the rotor passes it, to actuate the transducer (164). The second switch (166) is operated as before by a second pickup (172). The pickups (160, 176) are relatively angularly adjustable to vary injection period, and are angularly movable together to advance and retard injection, either by throttle control or by an advance-retard centrifugal mechanism. A second pair of pickups may be provided for pilot injection to help cold starting. A modified transducer (224, Fig. 5, not shown) has discrete sections (224a, b and c) energized separately by transistors (240a, b and c) whose bases receive successive trigger pulses from a source (244); discharge of all sections is by a single transistor (248) and diodes (254). Alternatively, a single transistor (258, Fig. 6, not shown) is operated by the trigger circuit (260) to apply the rectified output of a variable frequency source to the anodes of SCR's (264a, b and c) connected to each transducer section, one pulse from the trigger circuit (260) firing one SCR (264a) and the others being successively fired by adjustable time delay circuits (268, 270) between the SCR's. The anodes are all earthed through an SCR (272) to discharge the transducer.

Abstract: 1,252,626. Spirometer. P. K. MORGAN. 8 April, 1970 [10 April, 1969], No. 18461/69. Heading ASK. A spirometer comprises a bell-shaped container 11, with its open end immersed in a liquid, e.g. water, bath 12, divided into two equal-volume chambers 13, 14 each having an inlet pipe 15, 17 and outlet pipe 16, 18 respectively; the pipes 16, 17 are each connected by a valve electrically or pneumatically controlled 19, 20, to the atmosphere, whilst pipes 15, 18 are connected by flap valves 22, 23 to a mouth piece 21, which is connected to a pressure-sensitive device by line 25, which operates the valves 19, 20. The container 11 is counterbalanced by a weight 26 carrying pen 27 traversing a kymocyclograph 28. On inhalation, air is drawn from chamber 14 to the mouth-piece 21 as shown by arrows, valve 20 being closed. On exhalation, air passes through flap valve 22 to pipe 15 and into chamber 13. The increase in pressure in the line 25 trips the pressure-sensitive device which includes a pressure-sensitive switch 30 thereby making an electrical contact operating a relay 29, closing one valve 19, and opening another valve 20 to replenish the outer chamber 14. On subsequent inhalation, the reduction in pressure actuates a relay 29 so that air from the inner chamber 13 is exhausted through its outletvalve 19, whilst the outlet valve 20 for the other chamber is closed. The concentration of a tracer gas, e.g. carbon monoxide, may be analysed by using a line 24 in conjunction with the circuit shown in Figure 3, consisting a variable delay switch 31 and a vibrator diaphragm pump 32. On exhalation, the increase in pressure in line 25 ensures that no gas is drawn off along line 24 to an analyser. On inhalation, the decrease in pressure in line 25 actuates a switch 30 causing relay 29 to operate a pump 32 to remove gas from pipe 15 to line 24. Pumping continues until a variable-delay switch 31 cuts off power to the pump 32. The switch 31 is then reset by the closure of another switch 30 during the next exhalation. The kymocyclograph is used to ensure a steady flow of respiration during the analysis, and the air is drawn from the tidal part of the exhalation. In a modification, the valves 19, 20 are pneumatically controlled, so that they are responsive to pressure in the line 25.

Abstract: 1,257,494. Injection moulding. CONTINENTAL CAN CO. Inc. 8 April, 1969 [8 April, 1968], No. 17762/69. Heading B5A. [Also in Division B8] An article having a weakened portion, e.g. an easy-opening container is made by injecting thermoplastic material into two parts of a mould cavity and causing contiguous edges of the two portions of thermoplastic material to fuse together so as to form a line of inherent weakness. As shown in Figs. 1 and 3, an end cap 10 for a container comprises an annular portion 11 joined by a weakened portion 9 to a central removable portion 12. The annular portion 11 is formed by injection through gates 54, 56 and the central portion by simultaneous injection through a gate 55 into a mould 26, 27. Alternatively, valves V 1 , V 2 , V 3  may be used so that one portion of the article is formed before the other. Mould part 27 has an annular rib 50 to form the weakened portion 9. An annular venting chamber 24 is connected by ports 29 to a vacuum source (not shown). The gap (51) between the web 50 and the lower mould part may be so small as to prevent plastic material entering it, in which case the build-up of pressure in the mould cavities is used to cause relative axial shifting of the mould parts when full. Alternatively the gap may be initially completely closed. In Figs. 6 to 8 (not shown), the weakened portion is positioned midway between opposite faces of the can end which may be provided with an annular bead or beads (74, 75 or 84), on the adjacent portions. Fig. 11 shows a mould for making an end cap having a discontinuous weakened portion formed by a rib 124. Injection is effected through a single gate 131, the injected stream dividing into two portions, one to fill the annular cavity 130 and the other the cavity 128. In Fig. 13 the weakened portion is generally cylindrical in form, the annular and central mould cavity portions being displaced axially. Mould portion 157 is movable against the biasing force of springs 161, 162, or fluid motors.
