Patent GB-1026912-A (GB)
Title: Novel copolymers of methyl methacrylate
Inventor: NIELD ERIC
IPC: C08F22/36
Filed: 1963-04-18
Abstract: Novel copolymers are prepared by polymerizing a monomer mixture comprising 1 to 99% by weight of methyl methacrylate, 99 to 1% by weight of one or more N-aryl maleimides and 0 to 15% by weight of a copolymerizable ethylenically unsaturated compound. Suitable maleimides include N-phenyl maleimide optioally substituted by one or more halogen atoms or nitro, nitrile, aryl, aryloxy, aralkyl, aralkoxy, aryloxyalkyl, C1-4 alkyl or C1-4 alkoxy groups, and N-a -naphthyl maleimide and derivatives thereof.  As optional copolymerizable compound there may be used vinyl esters, e.g. vinyl acetate, esters of acrylic or methacrylic acid, e.g. methyl acrylate, ethyl acrylate, n-butyl methacrylate and 2-ethylhexyl methacrylate, vinyl chloride, vinylidene chloride, acrylonitrile, methacrylonitrile, styrene, a -methyl-styrene, halogenated styrenes, vinyl and isopropenyl ethers, e.g. vinyl isobutyl ether, dienes, e.g. 1,3-butadiene, glycol dimethacrylate and di-vinyl-benzene. The polymerization may be effected in bulk, solution, aqueous emulsion or aqueous suspension, using a catalyst such as azo-bis isobutyronitrile, azo-dicyclohexane-carbonitrile, a peroxy compound, e.g. benzoyl peroxide or lauroyl peroxide, or potassium persulphate and, if desired, a chain transfer agent, e.g. lauryl mercaptan.  The monomers may be partially polymerized to form a syrup which is then polymerized in a cell to form a sheet.  Continuous polymerization can be effected by the process described in Specification 875,853.  The copolymers may be combined with rubbery polymeric materials, e.g. copolymers of butadiene with styrene, methyl methacrylate or acrylonitrile; polyethyl acrylate; rubbery copolymers of C1-4 alkyl acrylates; rubbery copolymers of ethylene with e.g. vinyl acetate or methyl methacrylate.  The rubbery polymers can be cross-linked, e.g. by masticating or incorporating therein a cross-linking monomer. The rubbery polymer may simply be mixed with the copolymer of the invention, or the monomeric components of one of these polymers may be polymerized in the presence of the other preformed polymer. Other ancillary ingredients may be added during or after the preparation of the novel copolymers; such substances include fillers, e.g. glass fibres, pigments, e.g. aluminium sulphate, heat and light stabilizers, plasticizers, lubricants, flame retardants and mould release agents.

Abstract: 1455635 Transistor switching circuits INTERNATIONAL BUSINESS MACHINES CORP 8 April 1974 [25 May 1973] 15434/74 Heading H3T A circuit arrangement comprises a bistable circuit 2<SP>1</SP> with a pair of cross-coupled field effect transistors 10, 11 connected between its two input terminals 3, 4 so that when a potential is switched by a mechanical switch 5 from either one of the input terminals to the other, the potential of the former input is discharged and a single transition is produced at the output of the bistable. With the switch 5 as shown, transistor 10 is cut off giving a logical level "1" at input A1 and transistor 11 is conducting giving a logical level "0" at input B2. The output and inverted output are at "0" and "1" respectively. The bistable 2<SP>1</SP> comprises two cross-coupled CMOS NOR gates and when switch 5 moves to its other position transistor 10 is switched on and capacitor C1 discharges to turn off transistor 11. In this state the inverted output changes to "0" and the bistable takes up a stable state with A2, B2 both at logical "1", so that any bounce of switch 5 (making B2 logical "0") does not affect the output. The input transistors may be P channel type with the bistable formed as NAND gates Fig. 5 (not shown). P-channel input transistors may also be used with NOR gates in the bistable and N-channel with NAND gates Figs. 7, 6 (not shown) but added capacitances across the inputs to the bistable may be necessary to prevent contact bounce.

Patent GB-395853-A (GB)
Title: A process for the production of impregnating baths and printing colours containing arylides of 2.3 oxynaphthoic acid
Filed: 1932-06-04
Abstract: Impregnating-baths and printing-colours containing arylides of 2 : 3-oxynaphthoic acid are made by using as dispersing agents sulphonated or phosphatized compounds of the fatty series of high molecular weight which contain at least 9 carbon atoms in the molecule and which still contain free alcoholic hydroxy groups. Specified compounds are sulphonated unsaturated or partially esterified polyvalent aliphatic alcohols which still contain one or more free alcoholic hydroxyl groups, and the corresponding phosphatized compounds.  In examples (1) 2 : 3-oxynaphthoic acid dianisidide or a -naphthalide is dispersed with sulphonated oleic alcohol which still contains a free acloholic hydroxyl group, (2) 2 : 3-oxynaphthoic acid-o-toluidide is dispersed with ricinoleic alcohol sulphuric ester, which still contains a free alcoholic hydroxyl group (monosulphuric acid ester of octodecanetriol).  Sulphonated alcohols which still contain free alcoholic hydroxyl group are made by sulphonating unsaturated fatty alcohols containing at least nine carbon atoms at about 0 DEG  C. sulphonation taking place at the double bonds.  Ricinoleic alcohol (made by reducing ricinoleic acid ethyl ester with sodium and butyl alcohol) thus yields the monosulphuric acid ester of octodecanetriol.  Sulphonated partially esterified polyhydric alcohols containing more than nine carbon atoms in the molecule are made by esterifying the alcohols obtained by reducing sugars with fatty acids and sulphonating the esters so that one or more hydroxyl groups remain free.  In an example, mannitol is treated with concentrated sulphuric acid and oleic acid. Phosphatized compounds are made as follows: (a) mannitol is treated with anhydrous phosphoric acid and phosphorus pentoxide and then with oleic acid, (b) hydroxy stearic alcohol (1 : 12-octadecanediol) is treated with chlorinated acetylphosphorus acid (from phosphorus trichloride and acetic acid), (c) ricinoleic alcohol is treated with acetylchloride and orthophosphoric acid, (d) oleic alcohol is treated with acetyl phosphoric acid (from phosphoric acid and acetic anhydride).

Abstract: 999,816. Engine stop gear. ROBERTSHAW CONTROLS CO. April 25, 1962 [May 24, 1961], No. 15829/62. Heading F1K. [Also in Division G3] A control system suitable for interrupting the fuel supply to an internal combustion engine 70, Fig. 5, in the event of an excessive bearing temperature detected by a feeler 140, or in response to other conditions such as fuel supply pressure or engine vibration, comprises a manual fuel control valve 74 and a pneumatically operated fuel valve 76 which, in the absence of pressure in a line 108, closes a port 78 and connects a port 82 to a vent 80. To start the engine, the valve 74 is opened after which a valve 92 is operated from a position in which it connects a line 98 with a vent 94 to a position in which it allows air pressure from a source 88 to pass into a line 100, a port 116 of a valve 114 being closed. A valve 10 allows air to pass to a line 28 and thence through a check valve 112 to lines 130, 128 and 104, 106. Provided a valve 132 actuated by the feeler 140 is closed, and any other valves connected to a line 136 and controlling vents in response to other engine conditions are also closed, pressure can build up in the line 128 to operate the valve 114 to interconnect ports 116, 120 so that pressure is applied to the fuel valve 76 to supply fuel to the engine and, through a line 126, to a diaphragm 58, Fig. 2, of the valve 10 whereby the closure member 34, normally opened by a spring 42, is moved on to its seat 32. The engine will continue to run until the line 136 is vented, when the valve 114 will vent the line 124 to cut off the fuel supply to the engine and allow the diaphragm 58 to be moved by its loading spring 60 to withdraw a rod 46 from contact with the closure member 34. The latter will, however, remain closed due to the supply pressure from the line 100 being effective in a chamber 20 whilst the pressure in the line 28 will have been bled through a restriction 110. The engine cannot, therefore, be restarted until the valve 92 is first operated to vent the line 100 to allow the closure member 34 to be opened by its spring.

The subjectmatter of this Specification is modified by including 'in the bath a chamber immersed in the filling material through which the elongated body is passed. The filling material is caused to flow continuously into and out of the chamber by pumping it from the bath into the chamber at a pressure considerably above atmospheric pressure whereby the rate of flow of the material through the chamber and its pressure purge the interstices of the body of air thereby ensure substantial filling of the interstices. As shown, liquid filling material is fed into bath 1 from pipe 7 regulated by valve 8 and maintained in the liquid state by heater 6. Cable C is fed into and out of bath 1 via dies 11 and 12 which are cooled by fins 14 thereby preventing leakage of material from the bath.

Abstract: 560,960. Steam traps. ARMSTRONG, C. M. C. Nov. 13, 1942, No. 16094. [Classes 64 (ii) and 123 (ii)] [Also in Group XVIII] An expansion tube 1, Fig. 1, mounted in a frame 2 is connected at the ends to the fittings 5, 6 of a gauge glass 4. The lower end of frame 2 is connected to the short arm of a pivoted lever 8, the long arm of which is connected by wire or rod 10 to the operating lever 11 of a steam whistle 12. Steam is admitted to the tube 1 through a tube 17 terminating at its lower end at the desired water level, and having a small throttling orifice 18. When a rising water level closes the tube 17 the main admission of steam to the tube 1 is cut off, the restricted admission through orifice 18 being insufficient to prevent condensation, so that water rises in the tube 1 and the cooling effect and contraction of the tube cause an actuation of the whistle 12. If the water level falls abnormally, the increased exposure of the tube 1 to steam causes an actuation of the lever 11 in the reverse direction, which also admits steam to the whistle. The device may also actuate a switch controlling a red lamp, or a recorder, or it may control the feed water supply. As applied to a steam trap, Fig. 2, the upper end of the steam tube 17 is connected to the steam space of the trap 20, and the contraction of tube 1 on a rise of water level actuates a pivoted lever 23 which is connected to the release valve 26. The lower end of tube 1 is connected through drain valve 30 to the water space of chamber 20. Specification 560,187 [Group XV] is referred to.
