Title: Stable aqueous emulsions of copolymers
IPC: C08F2/22
Filed: 1962-07-18
Abstract: Stable aqueous copolymer dispersions comprise (a) olefinically unsaturated monomers capable of copolymerizing with acrylic acid monomers capable of copolymerizing with acrylic acid derivatives and (b) 0.5 to 50% of an acrylic acid amide derivative of the general formulae I <FORM:1002451/C3/1> where R1 represents a hydrogen atom or a methyl group and Z represents a saturated aliphatic hydrocarbon radical containing at least one hydrophilic group Y.  The hydrophilic group Y may in particular be halogen, -COOH, -SO3H, OR2, -CN, -NO2 and <FORM:1002451/C3/2> in which R2 in both cases represents a closed alkyl having from 1-5 carbon atoms and n represents a whole number from 1 to 25.  Preferred acrylic acid amides for use in the production of the aqueous dispersions include the methylol ether derivatives of N-methylol acrylic acid amide in which the etherifying group corresponds to a radical of the formulae -(CH2)x-Y, that is compounds of the general formula II <FORM:1002451/C3/3> in which Y has the same meaning as given above and x indicates a whole number of from 1 to 20.  The preferred acrylic acid amides include compounds of the general formulae I above in which (a) Z represents a radical of the general formula <FORM:1002451/C3/4> in which n represents a whole number between 1 and 25, (b) Z represents a group <FORM:1002451/C3/5> (c) Z represents a group <FORM:1002451/C3/6> in which Hal represents a halogen atom in particular chlorine or bromine.  Suitable olefinically unsaturated monomers which are copolymerizable with compounds of the above-mentioned type are (a) a ,b -olefinically unsaturated monocarboxylic acids and their derivatives, (b) aromatic and aliphatic vinyl compounds, (c) conjugated cholefins, (d) methylol compounds of acrylic acid and methacrylic acid, (e) Mannich bases of acrylic and methacrylic acid amide. The amounts of the monomers (d) and (e) are preferably not in excess of 15% based on the total weight of monomers employed.  Cross-linking monomers with several olefinically unsaturated may also be present in amounts of 0.01-10% based on the total weight of monomers. The aqueous mixed polymer dispersions are obtained by copolymerizing the above-described monomers in aqueous dispersion using cation-active, anion-active or non-ionic emulsifying agents or combinations of these, in a total amount of between 0.5-20% calculated on the total amount of monomers. Preferably, non-ionic emulsifiers are employed and the polymerization is carried out at temperatures between 10-80 DEG  C. at a pH of 3-9. 0.01-5% based on total amount of monomer of an inorganic per compound is used as catalyst.

Abstract: 279,452. Siemens & Halske Akt.- Ges. Oct. 19, 1926, [Convention date]. Thermionic amplifiers. - A gain regulator for thermionic amplifiers comprises means to regulate the grid bias of the valves by branching off a portion of the signal current before the valves and rectifying it. The Figure shows an amplifying valve w fed through a retardation line l, the grid bias of which is controlled by the rectifying valve g and the net work c, r. Part of the input is applied to an amplifying valve v, the grid of which is similarly controlled to the valve w and the amplified voltage applied to the rectifying valve g. The retardation line l is preferably so proportioned to the network c, r that regulation of the amplifier w takes place before the signals are applied to it. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification in which a part of the output is applied to the rectifying valve and the amplifying valve v and the retardation line l are dispensed with. This subject-matter does not appear in the Specification as accepted.

First valve means 37 includes a seal member 36 normally closing port 20 under the bias of a compression spring 66 acting on the end of a lever 32 pivoted to the housing 14. Second valve means 50 includes a plate 44 with a captive "O" ring 46 which normally seals port 18 under the action of swivel plate 42 pivoted at 52 to housing 14, attached to plate 44 loosely by spools 48, and urged against plate 44 by tension spring 56 and the pressure in chamber 10. The probe 24 is inserted through an "O" ring 26 in port 16 and engages an inclined end surface 30 of lever 32 to open port 20 whereby evacuation of chamber 10 begins. The probe 24 is then stopped by a lever 38 pivoted to housing 14 and connected to plate 42 by a link rod 40, the force of probe 24 on lever 38 being at this time insufficient to overcome the forces of the spring 56 and chamber pressure acting on plates 42, 44. When a predetermined low pressure is attained, the lever 38 is able to overcome these forces and is swung down in direction 58 by probe 24. This pulls valve means 50 away from port 18 in direction 60 and the probe 24 then moves on into port 18 and vacuum system 22.

Abstract: 1456579 Foundry moulding machine HENRY WALLWORK & CO Ltd and C M G WALLWORK 19 June 1975 [26 June 1974] 28261/74 Heading B3G A machine for automatically producing foundry moulds comprises two reciprocatory slider plates 1, 2 each having at least one moulding aperture 3 therethrough such that in one position of the plates apertures therein are aligned and separated by a stationary bolster plate 4; in this position platens 5, 6 carrying pattern plates enter the apertures and define moulding chambers into which sand is blown to form flaskless moulds back-to-back, one being a cope and the other a drag, the plates being then moved to positions where rams 9, 10 push the moulds from their apertures. Sand is blown into the aligned apertures through slots 8 from a blowhead 11 with nozzles 13 and the sand is pressed by the pattern plates. The moulds are pushed on to tables 15, Fig. 2, by the rams, which are swung about horizontal axes 16 whereby the copes and drags have their patterned faces directed downwards and upwards respectively. Each mould is gripped by the jaws 20 of a carrier 21 slidable on rails 22 and transferred to an intermittently driven conveyer; each conveyer thereby comprises a line of alternate copes and drags. Each cope, during its transfer, has a sprue cut into it by a cutter 24, Fig. 3, mounted on a carrier. When a cope reaches the end of a conveyer it is lifted by jaws 25 allowing a drag to be brought beneath it and to be aligned by means 28; the aligned cope and drag are pushed by a ram 29 towards the installation centre-line, and a pusher 30 pushes the mould assemblies on to a track 32 where casting is effected, and cooling takes place on a conveyer 36. The moulds and castings are received by a barrel 37 where they are broken up and the castings extracted. In a modification, the slider plates each comprise a single moulding aperture and are reciprocated vertically; alternatively the slider plates may be arranged with the axes of their apertures vertical so that the pattern plates are driven vertically into them.
