Title: Improvements in and relating to laundry ironing machines
IPC: D06F65/08
Filed: 1948-10-01
Abstract: 654,010. Ironing-machines. NAAMLOOZE VENNOOTSCHAP MACHINEFABRIEK REINVELD. Oct. 1, 1948, No. 25600. Convention date, Oct. 27,1947. [Class 138 (ii)] In a laundry ironing-machine comprising means for varying the pressure between a roller 4 and bed 5, the roller or the bed being associated with a lever system whereby they can be moved towards and away from one another by means of a shaft 12 associated with mechanism for imparting rotary movement to the shaft, all members of the lever system are rigid and a resilient element is interposed in the mechanism. In one example (Fig. 2), bearings 6 for the roller 4 are mounted on horizontal arms 13 pivoted to the frame, and crank-rods 8 are pivotally connected at one end to the bearings and at the other to cranks 10 keyed to the shaft 12. A toothed segment 14 is keyed to the shaft 12 and meshes with a worm 16 keyed to a shaft 15 movable lengthwise in bearing-blocks 17, 18. A collar 19 on the shaft 15 abuts against bearing 18 and a spring 20 is interposed between bearing 17 and the worm 16. By turning a hand wheel 15a on shaft 15 in one direction the roller may be lifted away from the bed 15 in a circular path about the axis of rotation of arms 13, and by turning the hand wheel in the other direction the roller is urged by the spring 20 against the bed. A scale 21 enables the operator to read the distance from collar 19 to block 18 corresponding to the length of spring 20, this being a measure of the pressure between the roller and bed. In a second example (Fig. 3, not shown) the collar 19 on shaft 15 is replaced by a spring interposed between the worm 16 and bearing 18. In a modification the two springs are replaced by a single spring which through part of its stroke is under tension and through another part is compressed. In further modifications the cranks 10 may be replaced by eccentrics and the coiled springs by rubber buffers. In an alternative construction the roller is supported in stationary bearings and the bed adapted to be moved towards the roller by means of the lever system and mechanism described. The Specification as open to inspection under Sect. 91 comprises also the replacement of the coiled springs by counterweights. This subjectmatter does not appear in the Specification as accepted.

Title: Means permitting of evaporating or of de-gasifying in vacuo continuously a liquid contained in any vessel or apparatus
IPC: B01D1/30
Filed: 1932-09-15
Abstract: Liquids are evaporated or degasified by drawing the liquid from a tank 20 up through a pipe 4 into an evacuated vessel 1 so that the liquid passes through a heater element 7 and then impinges on a baffle 9, finally falling downwardly over perforated plates 8. The vapour and gases evolved are drawn through a pipe 3 and air condenser 10 by a pump 21.  Residual liquid passes in heat exchange with the cold liquid through a vessel 19 and is pumped by a <PICT:0392044/III/1> pump 16 to a receiver 22, the action of the pump being increased by recirculating part of the liquid through an injector 17. Liquid level in the vessel 1 is maintained constant by a float 6 actuating a clack valve 5.
Patent GB-755485-A (GB)
Title: Improvements in or relating to the method of treating low boiling tar acids
Inventor: NEUWORTH MARTIN BRANDT
IPC: C10C1/18
Filed: 1954-09-06
Abstract: Thiophenols are removed from tar acids boiling below 230 DEG  C. by passing a solution of tar acids containing thiophenols in an organic polar solvent, e.g. aqueous methanol, at a liquid hourly space velocity of less than 3 in contact with an anion exchange resin which derives its exchange activity from strongly basic (e.g. quaternary ammonium) groups, for a period which is longer than that required for the resin to become saturated with acids, but not longer than that required for the resin to become saturated with thiophenols, and recovering the effluent solution containing the purified tar acids, which may be isolated by removing the solvent.  Where the tar acids are contaminated by oxidation products of thiophenols such as disulphides, the tar acids may be pretreated by passing an acidic solution thereof through a zinc reductor to reduce the oxidation products to thiophenols, after which the purification process is carried out as above.  The effluent solution which has been purified by treatment with an anion exchange resin may be freed from bases and traces of the anion exchange material which have been carried into solution, by subsequent treatment with a cationexchange resin.  The preferred method of carrying out the invention, described by reference to accompanying drawings comprises continuous removal of the thiophenols by passing a solution of tar acid in an aqueous organic polar solvent such as ethanol, acetone, methyl ethyl ketone or preferably methanol through an anion exchange resin which derives its exchange capacity from quaternary ammonium groups, passing the resulting effluent solution through a cation exchange resin which drives its ion exchange activity from sulphonic or carboxylic groups, removing the solvent from the effluent by distillation and separating the tar acids from the residual mixture of water and tar acids, by decantation.  The anion exchange resin and the cation exchange resin may be regenerated by washing with aqueous alkali and a solution of a strong acid in an organic polar solvent such as methanol respectively.  Examples describe the application of the invention to commercial crude tar acid and to a synthetic mixture of a phenol and thiocresol.

Title: Improvements in or relating to the production of dl-histidine and to intermediate therefor
IPC: C07D233/64
Filed: 1945-10-04
Abstract: Compounds of the general formula <FORM:0599481/IV/1> where R represents an alkyl group, Z an aliphatic acyl group having a maximum of six carbon atoms, and Y a cyano or carbalkoxy group, are manufactured by condensing a 4 - (halomethyl) - imidazole or a hydrohalide thereof with an alkyl lower aliphatic acylaminomalonate or acylaminocyanoacetate in the presence of an alkaline condensing agent, and are converted into dl-histidine by treatment with a strong mineral acid.  The histidine is obtained as the salt of the mineral acid employed, which may be, for example, hydrochloric acid, but is preferably sulphuric acid, since the sulphate is more readily converted into the free amino acid by removal of the sulphate ion as barium sulphate.  In examples: (1) ethyl cyanaceturate is condensed with 4-(chloromethyl)-imidazole hydrochloride in the cold in the presence of a solution of sodium in excess of anhydrous ethanol to produce ethyl 2 - acetamido - 2 - cyano - 3 - (4 - imidazole) - propanoate, which is refluxed with dilute sulphuric acid and the product treated with barium hydroxide to liberate dl-histidine; (2) the ethyl cyanaceturate in (1) is replaced by ethyl acetamidomalonate, the intermediate product being ethyl 2-acetamido-2-carbethoxy-y 3-(4-imidazole)-propanoate.  Methyl propionyl-aminomalonate is specified as an additional starting material and sodium methoxide, potassium or calcium ethoxide and sodamide as condensing agents.
