Patent GB-829887-A (GB)
Title: Process of producing terephthalic acid mono-(beta-hydroxy ethyl) ester and its metalsalts
Filed: 1957-10-31
Abstract: The mono-(b -hydroxyethyl) ester of terephthalic acid is produced in a pure state by heating an alkali metal salt of a lower alkyl mono-ester of terephthalic acid with ethylene glycol whereby ester-interchange takes place, then adding a salt of an alkaline-earth metal, which is soluble in ethylene glycol, to precipitate the required mono-ester in the form of its alkaline-earth metal salt, filtering off the precipitate, suspending it in water and finally liberating the pure mono-a b -hydroxyethyl) ester with strong mineral acid.  In Example (1), terephthalic acid monomethyl ester is dissolved in ethylene glycol while heating the mixture to 125 DEG C.; and sodium bicarbonate is then added with stirring.  Methanol, water and excess glycol are then distilled off under reduced pressure; and pulverized anhydrous calcium chloride is added, with vigorous stirring, to the clear solution of the sodium salt.  The calcium salt of the mono-(b -hydroxyethyl) ester crystallizes out while the mixture is still hot.  The crystals are filtered off, washed with methanol and water, and dried.  The calcium salt is finally suspended in hot water, and the suspension is made acid to congo red by addition of dilute hydrochloric acid.  On cooling, terephthalic acid mono-(b hydroxyethyl) ester crystallizes out. In Example (3), the potassium salt of the mono-isopropyl ester is the starting material; and magnesium acetate is used to precipitate the hydroxyethyl ester.  In Example (4), the sodium salt of the monobutyl ester is the starting material; and barium chloride is employed in the second step.  Specification 727,989 is referred to.

Abstract: 1422672 Delayed action catalyst system CHEVRON RESEARCH CO 17 July 1973 [19 July 1972] 34077/73 Headings C3P and C3R [Also in Division E1] The resinification of acid catalysed liquid resin precursors is controllably delayed by using as catalyst a mixture of (a) a material which on hydrolysis releases an acid and (b) a base in an amount less than the stoichiometric equivalent of the acid released by (a) but sufficient to cause the desired delay. Examples relate to the use as resin precursors of furfuryl alcohol, with or without formaldehyde or furfuryl alcohol prepolymers, and the use of urea-formaldehyde or phenolic resin prepolymers. Preferred material (a) is α-trichlorotoluene; also used in the examples are α-mono- and di-chlorotoluenes, and benzenesulphonyl chloride. Used as the base, (b) in the examples are pyridine, triethylamine, triethanolamine, tri-n-butyl amine, and cyclohexylamine. Where the resin precursor is not or does not contain a hydrolytic agent for the material (a), such should be provided and a diluent may also be present. Specified are methanol, acetone and benzene. Uses.-Rendering earth works impermeable, e.g. in the bore of an oil or gas well; impregnating wood, fibre glass, felt or burlap; bonding wood, glass, ceramics, coal, nut shells, sand or soil; preparing sand-type moulds; preparing engineering plastics.

Title: Improvements in or relating to gas turbine plant
IPC: F02C5/10
Filed: 1954-11-24
Abstract: 762,742. Gas turbine plant. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.- GES. Nov. 24, 1954 [March 31, 1954], No. 34087/54. Class 110 (3). [Also in Group XII] A gas turbine plant comprises a combustion chamber of the oscillating gas column type which discharges into an air mixing tube into which secondary air is intermittently aspirated through a turbine. The combustion chamber 1, which is of the oscillating gas column type having inlet non-return valves 4, discharges into an air mixing tube 2 having air inlet non-return valves 6. A diffuser 7 is arranged at the discharge of the tube 2. Fuel is admitted to the combustion chamber 1 through the inlet 5 and ignited by a sparking-plug 10. A pressure wave travels down the tube 2 and upon its arrival at the diffuser 7 a negative pressure wave is reflected back into the tube 2. This wave causes air to be drawn in through the turbine 3 and non-return valves 6. The air supplied to the combustion chamber also passes through the turbine 3. To compensate for unbalance in the supply to the turbine 3, reservoirs may be fitted in the pipes leading to the non-return valves 4, 6. A number of combustion chambers may be used to operate a single turbine. In a modification, Fig. 2 (not shown), the air supply to the turbine 3 is preheated in a heat-exchanger arranged at the discharge of the diffuser 7. In a further modification, Fig. 3 (not shown), the turbine 3 is actuated by the air supply to the non-return valve 6 only. In this arrangement, the turbine 3 drives a compressor which supplies air to the non-return valve 4 and the inlet of the turbine 3. In a modification of this arrangement the compressor supplies air only to the non-return valve 4 and the air to the turbine 3 is heated in a heatexchanger arranged in the discharge of the diffuser 7. In a further modification, Fig. 5 (not shown), the air passing to the non-return valve 6 passes through a jacket surrounding the combustion chamber 1. Specifications 368,564, [Group XXXIII], and 701,175 are referred to.

The frame is provided with a lower fixed cutting shelf 16 having a detachable steel bar 34 to cooperate with the knife and an upper shelf 17, rotatable about a shaft 18 that is removably secured by a bayonet socket catch in the frame. The knife carrying slide comprises side rails 24 and a bridge piece 25 and carries an outer blade 28, an inner blade 29 and a comb-blade plate 30 bridging over the space between the blades 28, 29. All the blades are detachable for sharpening or replacing and are adjustable for the cutting required. The outer blade may be used in co-operation with either the upper or the lower shelf but the upper shelf only can be used with the inner blade and the comb-blades. The outer blade is screwed to the side rails 24 and is preferably formed with an inclined edge. The blade 29 is supported by side bars 35 connected together by a transverse bar 37 that also carries the combblade plate 30 of which the individual blades project from a bar 38. The bar 38 may be secured on the bar 37 so that the comb-blades project either about up to the plane of the blade 29 or about twice that distance. The bar 37 is positioned on the bridge-piece 25 by studs 50 and is held thereon by swing-bolts 40. The lower blade 28 is used for cutting slices, the material to be cut being pressed up against an adjustable gauge plate 46.

Abstract: 429,939. Induction relays. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. Dec. 8, 1933, Nos. 34622 and 34623. Convention dates, Dec. 23, 1932 and Oct. 25, 1933. [Class 38 (v)] An induction relay adapted for optional manual actuation, comprises an induction disc 3 which drives a cogwheel 4 loosely mounted on a spindle 5 and pressed by a spring 6 into frictional engagement with a disc 7 fixed on the spindle. A spring 12 is fixed at one end to the spindle and at the other end to a fixed bearing 8. An insulating plate 16 is pivoted at 15 and has a catch member 25 bent at its end 26 to engage a catch 28 of a spring mounted plate 27. On the plate 16 are mounted fixed contacts 17 and springs 18 carrying movable contacts 19 and provided with strips 20 carrying rollers 22 which engage cams 13 on the spindle 5, arranged one each side of a cam 14. When the coil controlling the induction disc 3 is energized, for instance by a time switch, the spindle 5 is turned against the action of the spring 12 to turn the cams 13 to allow the contacts 17, 19 to engage. A projection 11 on the disc 7 engages a shoulder 10 on the bearing 8 and stops the disc 3 which remains in this position until the coil is deenergized. The spring 12 then returns the spindle 5 to open the circuit, the projection 11 on the disc 7 coming to rest on a projection 9 on the bearing 8. In order to close the circuit manually when the cams 13 are set to the off position, a knob 30 is provided having a spindle 32 carrying a cam 33 which is turned against the action of a return spring 34 to engage the strip 27 to release the catch 28. The plate 16 then turns on its pivot 15 to allow the contacts 17, 19 to close. When the spindle 5 is again turned by the induction disc a cam 14 engages the strip 25 to reset the catch 28. A second knob 31 operates a cam 37 which engages a bar 24 connecting the strips 23 to bend the springs 18 so far as to place the contact 19 out of reach of the contact 17 in either position of the plate 16. In a modification, the cam 37 engages with a strip carried by a spark shield 41 on the plate 16 to reset the plate manually.
