Title: Improvements in the production of electrical insulating materials from resins
IPC: C09F1/00
Filed: 1930-10-24
Abstract: Resinous products for insulating purposes, derived from natural resins or resin acids, and consisting of the anhydrides of the resin acids and the lactones of hydroxy-acid constituents of the resins, are manufactured by dissolving the resin in alcoholic alkali and treating it with an organic acid chloride, preferably at raised temperature, whereby the ester of the solvent is formed and may be distilled off or may be allowed to remain as a constituent of the refined resin.  The products may be employed in admixture with oils for impregnating electric cables, or for the manufacture of insulating varnishes.  In an example colophony is dissolved in ethyl-alcoholic soda solution and treated with acetyl chloride, producing a pure resin acid anhydride together with ethyl acetate which is distilled off.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the manufacture of resin acid amides and esters by treating the products of the above process with amines and with high-boiling alcohols.  In examples the product of the example above is treated with b -naphthylamine and with benzyl alcohol. This subject-matter does not appear in the Specification as accepted.

Patent GB-197910-A (GB)
IPC: B01D25/00
Filed: 1922-11-24
Abstract: 197,910. Jung, H. May 19, 1922, [Convention date]. Fluid-actuated valves.-The, valves for carrying- out a series of operations, such as filtering, washing &c. in pressure filters are all operated by fluid power under the automatic control of switch mechanism, the arrangement being such that the period of any operation can be independently adjusted. The fluid for operating the valves 1 of the filter is supplied to the valves by lines 12 under control of valves 13 operated by cam discs 19 on a shaft 20 rotated intermittently by a pawl engaging a ratchet wheel 21 and adapted to be reciprocated by a spring-loaded piston working in a pneumatic cylinder 22. The cylinder 22 is alternately supplied with fluid under pressure and connected to atmosphere by a valve 24, operated by a cam disc 27 on a shaft driven by reducing-gearing from a pneumatic turbine 28. The normal speed of the turbine is determined by the air supply thereto through a main regulating-valve 16 and a regulating-valve 32, but this speed may be increased or reduced to shorten or lengthen the period of any particular operation by supplying additional air to the turbine or by supplying air to a braking turbine on the same shaft. The supplementary air supply is governed by one of a series of regulating valves 35, one member of the series being supplied with air for each position of a plug valve 46 on the end of the shaft 20. A four-way plug valve 11 delivers pressure fluid to a reversible motor for operating gear for discharging precipitate from the filter. At the time for this operation, the air supply to the turbine 28 is automatically diverted to an auxiliary turbine from which the pneumatic operation of the valve 11 is controlled. A dial plate is provided with scales to indicate the point in the series of operations reached at any particular moment, and others by means of which the positions of the valves 16, 32 and 35 are indicated and can be regulated. Modified apparatus is described in which passages in the plug valve 46 perform the functions of some of the valves 1.

Title: Improvements in or relating to preparation of monomeric glycol terephthalates
IPC: B29C35/02
Filed: 1956-10-23
Abstract: Polyalkylene terephthalates may be produced by the esterification of terephthalic acid with a glycol of the formula HO(CH2)nOH, where n is 2-10, in the presence of titanium dioxide in 0.01 to 0.2 per cent by weight of the terephthalic acid, as a catalyst and then further heating the monomeric terephthalate so formed, preferably with the application of a vacuum, without the addition of another catalyst. An example describes the preparation of a high molecular weight polyester using 0.025 parts of titanium dioxide per 50 parts of terephthalic acid, and heating with 300 parts of ethylene glycol to 195-196 DEG  C., removing the water and excess ethylene glycol and then further heating to 275 DEG  C. for one hour at a pressure of 15 mm. and a further 2 1/2 hours at a pressure of 1 mm.  Other glycols which may be used are trimethylene glycol, butanediol-1,4, and decanediol-1,10.ALSO:Terephthalic acid is esterified with a glycol of the formula HO(CH2)nOH, where n is 2-10, in the presence of titanium dioxide as a catalyst in 0.01 per cent to 0.2 per cent by weight of the terephthalic acid.  The reaction may be carried out batchwise or continuously.  Terephthalic acid is preferably heated with an excess of glycol in the presence of titanium dioxide at a temperature of about 110 DEG -260 DEG  C. after which the excess glycol is removed by distillation.  The titanium dioxide may be employed in a finely divided or powdered form and dispersed directly into the reaction mixture, or may be dispersed in the glycol which may then be admixed with the terephthalic acid.  The titanium dioxide can also act as an ester interchange catalyst thus the esterification and polymerization to high molecular weight polyesters may be carried out concurrently. Examples are given of the esterification of terephthalic acid and ethylene glycol. Other useful glycols are trimethylene glycol, butanediol 1,4 and decanediol-1,10.

Title: Improvements relating to the supply of sump vapours to the mixture intakes of internal combustion engines
IPC: F02M25/06
Filed: 1939-12-16
Abstract: 535,438. Supplying sump vapours to charge. ANNESLEY, G. Dec. 16, 1939, No. 32364. [Classes 7 (ii) and 7 (iii)] The supply of sump vapours to the induction pipe is controlled by a valve 11 actuated by a plunger 12 and electromagnetic coil 14 supplied from the engine dynamo through a relay switch which cuts off the supply of current to the coil 14 when the engine is idling, owing to the reduced voltage from the dynamo. As soon as the engine attains a pre-determined speed, the dynamo voltage is sufficient to close the relay, switch and supply current to the coil 14 to open the valve. A thermostat may be included in the circuit so as to prevent the valve from opening until the engine reaches a certain temperature. The sump vapours may be heated on their way to the induction pipe by strapping the pipe through which they pass to the exhaust pipe, or by forming it into a coil within the exhaust pipe or within a box communicating therewith, or by passing the vapours through a chamber secured to the exhaust pipe and fitted with baffles. The casing of the valve 11 may be integral with the carburetter or induction manifold, with its outlet pipe 8 forked so as to supply the vapours to opposite sides of the induction pipe, if desired tangentially. In a modification, the stem of the valve 11 may pass through the plunger 12 with some axial lost motion, so that the plunger initially moves alone and attains some momentum before striking a stop on the valve stem to lift it.
