Title: Improvements in the production of polyesters
Inventor: LINCOLN JAMES
IPC: C08G63/78
Filed: 1952-05-21
Abstract: Polyesters are obtained by heating in a glycol medium, or a water medium under pressure, a salt of a strong base and a dicarboxylic acid which is a p,p1-dicarboxy derivative of a compound containing a single benzene ring or of a compound containing two benzene rings linked directly or through carbon oxygen or sulphur atoms, with at least two nolar proportions of a halohydrin of a volatile glycol and heating the reaction product until a polyester is formed.  Suitable acids are for example, 2,5-dichloro-terephthalic acid, diphenyl-4,41-dicarboxylic acid, 3,31-dimethyl-diphenyl-4,41-dicarboxylic acid, a ,-bis-(paracarboxyphenyl) - alkanes, a ,o  - bis - (paracarboxyphenoxy) - alkanes and 1.5, 2.6 and 2.7-naphthalene dicarboxylic acids.  In the examples the ester obtained from sodium terephthalate and ethylene chlorhydrin is heated to form the polyester.ALSO:Polyesters are produced by a process comprising heating in a glycol as a reaction medium a salt of a strong base and a dicarboxylic acid which is a p,p1-dicarboxy derivative of a compound containing a single benzene ring or of a compound containing two benzene rings linked together directly or through carbon, oxygen or sulphur atoms, with at least two molar proportions of a halohydrin of a volatile glycol, separating the halide by-product, any unchanged halohydrin and any unchanged dicarboxylic acid salt, and thereafter heating the reaction product of the dicarboxylic acid salt and the halohydrin with evaporation of the glycol thereby formed, and any of the glycol reaction medium which still remains until a polyester is formed. Alternatively the reaction may be carried out in an aqueous medium, under pressure, at a temperature above 100 DEG  C.  Suitable dicarboxylic acids, of which the salts may be used as starting materials, are, for example, terephthalic acid, 2,5-dichloro-terephthalic acid, diphenyl-4,41-dicarboxylic acid, 3:31-dimethyl diphenyl 4,41-dicarboxylic acid, a ,o  - bis - (paracarboxyphenyl) - alkanes such as 4,41-dicarboxy-dibenzyl, a ,o -bis-(paracarboxyphenoxy)-alkanes such as a ,b -bis-(paracarboxyphenoxy)-ethane and 1,5-, 2,5- and 2,7-naphthalene dicarboxylic acids.  In the examples: (a) sodium terephthalate, ethylene chlorhydrin and ethylene glycol are heated, ethanol is added, the mixture is further heated and excess chlorhydrinin, glycol and ethanol are removed, leaving a solid which is then heated with water giving the bis-glycol ester of terephthalic acid with some mono-ester; the bisester so obtained is heated to give the polyester; (b) sodium terephthalate, ethylene chlorhydrin and water are heated to give the glycol ester of terephthalic acid; on heating this a polymer is obtained. Similar results are obtained by using the potassium salt of terephthalic acid instead of the sodium salt or the sodium salt or potassium salt of, for example, diphenyl-4,41-dicarboxylic acid.

Title: Continuous flow water heaters operating with two heating steps and including a flow controller
IPC: H01H35/40
Filed: 1966-03-24
Abstract: 1,143,106. Valves. A. ECKERFELD. 24 March, 1966 [15 April, 1965; 12 Nov., 1965], No. 13130/66. Heading F2V. [Also in Divisions F4, H1 and H5] An automatic water heater connected on its inlet side to a "continuously-on" water supply and on its outlet side to a service valve 50, comprises two electric heating elements 43, 43<SP>1</SP> arranged in a pipe 42<SP>1</SP> in the flow path, which are switched successively by opening the valve 50. Initial opening of this valve causes a flow responsive leaky piston member 32 to move so that a magnet 36 thereon closes a field-sensitive switch 39 to operate a relay 48, 49 whereby the first heater is switched on. A flow restricting collar 27 on a valve member 28 carried by the piston enters an orifice 20. On further opening of valve 50 the piston 33 rises to a second position and collar 27 passes out of orifice 20 so that the flow is increased. The increased pressure drop in the pipe 42<SP>1</SP> is sensed by a differential pressure responsive switch 45, 47 which operates to switch on the second heater 43<SP>1</SP>. Valve member 28 thereafter co-operates with a seat opening 23<SP>1</SP> to regulate the flow. In a modification, Fig. 1 (not shown), the piston 32 is replaced by a diaphragm (4). The diaphragm chamber has a Venturi outlet (7) of which the throat pressure goes to the opposite side of the disphragm. An actuating rod (10) from the diaphragm operates switches controlling both heaters. In low flow position a restricting collar (14) moves into an orifice (16) whilst in high flow position this collar has passed through the orifice and control is taken over by a valve member (15) co-operating with a seat (18).
Patent GB-813471-A (GB)
Title: Self-spraying wax polish and method for its production
IPC: C09K3/30
Filed: 1957-04-25
Abstract: A self-spraying wax polish is made by adding one or more waxes dissolved in a solvent to an aqueous solution containing a surface-acting agent and stirring at a temperature above the crystallization point of the wax, while continuing to add sufficient wax solution to convert the emulsion to a water-in-oil type, cooling this emulsion and finally adding a self-propellant gas under pressure.  In examples, there are prepared: (a) a solution of lanoline, candellila, carnauba, paraffin wax, or Gersthofen wax (a montan wax derivative), and a small amount of dimethyl siloxane dissolved in mineral spirit; and (b) an aqueous solution containing one or more higher fatty acids, borax, a surface-acting agent and ammonia.  Solution (a) heated to 71 DEG  C. is diluted with a petroleum solvent (Solvasso) and added slowly with stirring to solution (b) at room temperature.  The resulting water-in-oil emulsion is cooled rapidly and packed in aerosol cans with an equal quantity of a mixture of tri-chloromonofluoroethane and dichloro-difluoro methane.  Butane, isobutane, methylethyl ether and a range of fluorinated hydrocarbons are specified as alternative gas propellants.  Waxes used include beeswax and synthetic waxes of the ester type.  Surface-active agents used include polyoxyglycol ethers and esters, fatty amine condensates, salts of fatty acids, e.g. stearic and behenic acid, or sulphonated derivatives thereof, or salts of alkyl aryl poly ether sulphonates.  Examples of organic polysiloxanes are specified including polyalkyl, aryl compounds in which one or more H atoms are replaced by halogens, nitrogen or phosphorus.  The composition is applied to any surface to be polished by opening the valve and directing the spray over the surface.  The solvents and propellant gas flash off leaving a surface from which the water dries out rapidly and may then be buffed.  The composition may include pigments and dyes.

IPC: F01L1/047
Abstract: 132,304. Thornycroft & Co., J. I., Thornycroft, T., and Barford, V. G. July 11, 1918. Valve-gear.-In multicylinder four-stroke-cycle engines containing one or more units of six or greater even number of cylinders, in which a single cam for each cylinder operates the exhaust and the inlet valve, the construction is simplified by making use of one pattern of camshaft unit for each cylinder unit adapted to be driven from either end according to its position in the engine. For this purpose, the successive cams counting from the left-hand end of a camshaft unit are set at 180 degrees to the corresponding cams counting from the right-hand end, and the spacing of the cams along the shaft is similar from either end. In accordance with this arrangement, the cams on the right and on the left of the centre of the cam shaft may, in some cases, be similarly arranged, but set clockwise with one another and anti-clockwise respectively on the two portions of the shaft. In Figs. 1 and 2, the setting of the cranks of a six-cylinder unit is shown at 1, 2, 3, 4, 5, 6, and the setting of the cams at 1<a>, 2<a>, 3<a>, 4<a>, 5<a>, 6<a>, The cylinders fire in the order 1, 4, 2, 6, 3, 5, the crank-shaft rotating in the direction shown by the arrow. Looking from the end A, the cams 1<a>, 2<a>, 3a are arranged anti-clockwise and the cams 4<a>, 5<a>, 6<a> are arranged similarly but clockwise. The two ends of the cam-shaft unit, and also the driving-means are provided with coupling-flanges with suitably spaced holes, e.g. spaced hexagonally; or suitably keyed sleeves or clutches may be employed, whereby two or more cam-shaft units may be connected together or to the driving- means in a definite angular position. Arrangements are described for twelve cylinders in line, and for two sets of twelve cylinders in line inclined at 90 degrees to one another.
