Title: Improvements in or relating to feedwater supply and heating process for steam boilers
IPC: F22D1/00
Filed: 1961-05-02
Abstract: 933,793. Feedwater supply and heating systems for steam boilers. R. B. REGAZZI. May 2, 1961 [May 2, 1960], No. 15918/61. Classes 64 (1) and 123 (2). In a feedwater supply and heating system for a steam boiler make up water heated by contact with the hot outer surfaces of the boiler shell, the exhaust gas duct from the boiler to the chimney and the lower part of the chimney itself, is mixed with hot condensate returning from power or heating plant supplied by the boiler and the mixture constituting the boiler feedwater is further heated to a temperature equally or exceeding the boiler water temperature by indirect heat exchange with the boiler exhaust gases. In the form shown, the boiler 1, the exhaust gas duct 2 and chimney 3 are provided with a jacket 5 into which make-up water is admitted through a float valve 4. The heated make-up water leaves the jacket through a valve 6 which is mechanically adjusted according to changes in water level in the boiler by a float 7, a pipe controlled by a non-return valve 9 allowing the water to recirculate through the jacket when the valve 6 is closed. The make-up water passes into a tank 8 in which it mixes with hot condensate admitted through a pipe 10. The mixed water flows by gravity through a pipe controlled by a non-return valve 11 into a lower tank 12. When the level in this tank reaches the highest point a float opens a valve 15 and closes a valve 16 respectively admitting steam from the boiler to the top of the tank 12 and closing a steam supply to the top of the tank 8. The steam pressure forces the mixed water from the tank 12 through a pipe controlled by a non-return valve 17 into and through a heating coil 19 disposed in the duct 2 and chimney 3 into a tank 21 disposed above the boiler. When this tank is filled a float actuates a valve 23 to admit steam from the boiler above the water level whereupon the water in the tank 21 passes by gravity into the boiler through a pipe controlled by a valve 25 and non-return valve 26. To provide for a continuous feed tanks 12A, 21A may be provided, valves being arranged so that as the tanks 12, 21 are being filled the tanks 12A, 21A are being emptied and vice versa.

Title: Water dispersible epoxy resins
IPC: C08J3/03
Filed: 1965-04-14
Abstract: A method for rendering a resinous epoxide compound (a) water dispersible comprises mixing (a) with at least 10 wt. per cent of the water-soluble acidified reaction product of an epoxide compound (b) having at least 2 oxirane groups and a monoamine having the formula R1R2NH, wherein R1 is an aliphatic radical having at least one hydroxyl group and R2 is hydrogen, or an aliphatic radical having at least one hydroxyl group, or an alkyl radical of up to 6 carbon atoms, in which the mol. ratio of active amine hydrogen to oxirane oxygen is less than 1:1.  Epoxide compound and resinous epoxide compound are defined as compounds containing hydrocarbon or polyether chains separating terminal oxirane groups, the chains containing aromatic and/or aliphatic radicals.  The compositions of resinous epoxide compound and acidified reaction product may be dissolved or emulsified in water together with optional ingredients such as lubricants, water-repellants and coupling agents.  When organosilicon water-repellants are used they may first be reacted with the resinous epoxide compound or with the reaction product of epoxide and amine, in which reaction catalysts may be used.  The aqueous dispersions are useful as glass-fibre forming sizes.  Acid salts of amine modified epoxide are prepared by reacting diethanolamine and 1,4-di-glycidoxybutane; or an epoxidized polybutadiene; and the diglycidyl ether of bisphenol A and ethanolamine or H2N-C-(CH2OH)3, in diacetone alcohol and acidifying with acetic acid to give a pH of 7.  Silicon-containing, modified epoxy resins are prepared by reacting 1,4-diglycidoxybutane, g  -glycidoxypropyltrimethoxysilane, ethylene-diamine and 1,6-hexylenediamine; the reaction product of 1,4-diglycidoxybutane and diethanolamine, and g -glycidoxypropyltrimethoxysilane, ethylenediamine and 1,6-hexylenediamine; and a diglycidyl ether of bisphenol A and g -amino-propyltriethoxysilane.ALSO:Glass fibres are coated with a forming size which is an aqueous dispersion of a resinous epoxide compound rendered water-dispersible by mixing with at least 10 wt. % of the water-soluble acidified reaction product of an epoxide compound having at least 2 oxirane groups and a monoamine, R1R2NH, wherein R1 is an aliphatic radical having at least one hydroxyl group and R2 is hydrogen or an aliphatic radical having at least one hydroxyl group or an alkyl radical of up to 6 carbon atoms, in which the mol ratio of active amine hydrogen to oxirane oxygen is less than 1:1.  The size may also contain lubricants, water repellants and coupling agents and in the case of the water repellants these may, if they are organo-silicon compounds be first reacted with the resinous epoxide compound or with the reaction product of epoxide compound and amine, if desired, in the presence of a catalyst.

Title: Improvements in or relating to apparatus for stopping the operation of internal combustion engines
IPC: F01P11/16
Filed: 1935-06-04
Abstract: 457,775. Engine stop-gear. GRECH, V. O., Harveys, Ardleigh, Colchester. June 4, 1935, No. 16079. [Class 122 (iv)] In stop-gear for an internal-combustion engine with ignition current supplied from a battery, a temperature-controlled ignition cutoff switch is provided in conjunction with a suction-operated switch which prevents the establishment of current when the engine is stopped. A manually-operated control determines the use of the gear. The head of an internal-combustion engine is supplied with current from a battery B and an induction coil C. The main switch is shown at D and a manually-operable, warming-up switch at E. The automatic cut-out has two insulated terminals F2, F<3> connected across the switch E. A spring contact F<4> is mounted on the terminal F<2> and may engage a contact F<6> on terminal F<3>. A bimetallic strip G is mounted on the cylinder head A and may engage the spring contact. A cylinder H with a spring-pressed suctionoperated piston carrying a spindle H<2> is arranged beneath the contact F<4>. When the switch D is closed and the engine started, the spindle H<2> is lowered. The contact F<4> engages the contact F<6>. The switch E is then operated to connect the terminals F<2>, F<3> in series with the ignition switch. When the engine temperature reaches a predetermined temperature, the strip G rises and disconnects the switch F<4>. The switch E is returned to its inoperative position. In the event of a prolonged delay in restarting the engine, the spindle H<2> prevents the contact F4 engaging the contact F<6> and thereby avoids waste of current. The temperature and suction controls may operate two switches in series.

Title: Process for the dispersing calcium carbonate in a non-volatile carrier
Inventor: CARLYLE ROBERT LEWIS
IPC: C10M159/24
Filed: 1958-05-20
Abstract: A stable dispersion of calcium carbonate in a non-volatile carrier is formed by (1) mixing under atmospheric conditions of temperature and pressure and in the absence of any added water, (a) an oil-soluble sulphonic acid or sulphonate, (b) a volatile solvent for the sulphonic acid or sulphonate, (c) a non-volatile carrier for the sulphonic acid or sulphonate and (d) an aliphatic alcohol solution of a basic reaction product of hydrogen sulphide with calcium hydroxide, a hydrate thereof or calcium oxide, the amount of this reaction product being 1.5-4 times that required to react with the sulphonic acid when the latter is employed, or 0.5-3 times the number of chemical equivalents when a sulphonate is used, (2) passing carbon dioxide through the mixture to convert any excess of the above-mentioned basic reaction product into calcium carbonate in the form of a dispersion whose particles have a diameter less than 0.25 microns and then (3) removing the residual solvents.  The sulphonates mentioned include alkyl, cycloalkyl or alkaryl sulphonates, petroleum sulphonates and substituted sulphonates such as diphenyl ether sulphonates, naphthalene disulphide sulphonates, diphenylamine sulphonates, dicetyl thianthrene sulphonates, dilauryl beta-naphthol sulphonates, dicapryl nitronaphthalene sulphonates, mono- and polychloro-substituted paraffin wax sulphonates and nitroso paraffin wax sulphonates.  Metal, ammonium and amine sulphonates are mentioned.  The volatile solvent (b) may be a low molecular weight alcohol (e.g. methanol), an aromatic hydrocarbon (e.g. benzene), an aliphatic hydrocarbon (e.g. hexane) or a petroleum distillate such as naphtha.  The non-volatile carrier (c) may be a mineral oil or high-boiling petroleum distillate, or a synthetic lubricant such as an aliphatic diester (e.g. di-2-ethyl hexyl azelate), a silicate ester or a polyglycol or ether thereof.  When the final dispersion is to be used as a lubricating composition, additional ingredients may be incorporated, such as zinc dithiophosphates, calcium/barium phenolate sulphides, methyl dichlorostearate, antifoaming agents, pour-point depressants and viscosity index improvers.  According to the examples, the aliphatic alcohol of (d) may be methanol ethanol, n- or iso-butanol or n-hexanol, while the carrier (c) may be mineral oil, hexa-(2-ethyl butoxy) disiloxane or di-2-ethyl hexyl azelate. The sulphonic acid (a) may be derived from mixed alkyl benzenes or from dinonyl naphthalene, or alternatively the barium salt or the ethylene diamine salt of dinonyl naphthalene sulphonic acid may be employed.  Specification 789,720 is referred to.
