Patent GB-723109-A (GB)
Title: High-speed printing presses for printing in different colours
IPC: B41F3/42
Filed: 1951-09-05
Abstract: 723,109. Printing-machines. NELKI, G. Sept. 5, 1951, No. 20993/51. Class 100 (2). A reciprocating flat-bed printing press comprises a device for supplying ink to a sub-forme inserted in a main forme and vertically movable between two positions so as to be level with main forme or a lower level, the device having at least one ink fountain below the main forme level, an ink roller, means for displacing the roller, such that the roller is guided in contact with the sub-forme when traversing the sub-forme. Printing-surfaces.-The main forme 2 is supported on a reciprocating bed 1, while an auxiliary forme 4 which prints in a colour different from that of the forme 2 is inserted in a chase 3 within the forme 2. The chase 3 is supported on rollers 5d secured to pivoted levers 5a carrying rollers 5e engaging the undersides of a pair of cams 7a. The forme 4 is normally depressed below the surface of the forme 2 by springs 6, but is raised when the cams 7a are depressed by an impression cylinder 21. Inking-apparatus.-The main forme 2 is inked by rollers 22a, 22b, while the forme 4 is inked by contact with a roller 13 supported in slots 9a of a pair of oscillating arms 9 urged into vertical position by springs 9b. The arms 9 are adapted to be held in extreme positions in which the roller 13 dips in ink reservoirs 14 or 15 by locking pins 17a or 17b engaging notches 16. The arrangement is such that the impression cylinder 21 releases the pins 17a, 17b by engagement with knobs 18a and 18b respectively. As shown, the cylinder 21 has just depressed the knob 18a, thereby releasing the arms 9. Further movement of the bed 1 in the direction A causes the arms 9 and roller 13 to be swung into their left-hand position by engagement with rollers 22b, such that the locking-pin 17b engages the appropriate notch 16. During the reverse stroke of the bed 1, the cylinder 21 depresses the knob 18b to release the pin 17b, thus releasing the arms 9 which return to their vertical position.

The washing water may flow in the same or in the opposite direction to the material. In the form shown the container 1 is divided into two longitudinal compartments a and b by a central partition 8 which carries obliquely disposed blades 14 on both sides which form troughs to pass the material along the container. The container is also divided transversely by a ring 13 and, to prevent surges of water, the blades 14<1> adjacent the ring in the second section and those adjacent the feed end in the first section are higher than the rest of the blades. The blades 14 adjacent the ring in the first section and adjacent the discharge opening in the second section are curved to direct the material, as shown in Fig. 1. Agitating members 18 projecting at right-angles from the wall of the container are also provided. A feed box c and a discharge compartment d are formed by rings 9 separating the divided and bladed portion of the container from the apertured end plates 4 and 5 respectively. The opening 6 in the end plate 4 is preferably surrounded by a perforated ring 7 to strain the outflowing water, and the feed box is provided with scoops 10 which are attached to the partition 8 which projects a short way into the feed box. The scoops are shaped so as to feed material alternately to the compartments a and b. In the discharge compartment d the washed material is raised by scoops 21 and discharged through the aperture 6<1> into the innermost of a series of concentric conical screens 22, 23 where it may be rewashed by sprays of water. Water is supplied to the container by a pipe 19 which enters the discharge compartment d and which may be connected to a conduit which discharges the water directly into the lowermost of the compartments a, b.

Patent GB-748801-A (GB)
Title: Improvements in or relating to new chemical compounds
Inventor: TAYLOR REGINALD JAMES
IPC: C07D315/00
Filed: 1952-08-08
Abstract: The invention comprises lactones of aliphatic epsilon-hydroxy saturated straight-chain carboxylic acids containing 9 to 14 carbon atoms.  They may be prepared by dehydrating the appropriate acid or de-alcoholating the alkyl ester.  The acid or ester may be formed by reducing the epsilon-keto acid or an alkyl ester thereof with, for example, aluminium isopropylate.  The lactones may also be prepared by directly oxidizing the a -alkylcyclohexanone by use of Caro's acid or a mixture of sulphuric acid and hydrogen peroxide.  In the example: cyclohexanone is condensed with butanal and the product is dehydrated by heating with oxalic acid to give butylidene cyclohexanone.  This is reduced with hydrogen in the presence of palladized charcoal to give butyl cyclohexanone which is oxidized with Caro's acid and the product saponified with alcoholic KOH to give epsilon-hydroxy decanoic acid.  This is lactonized in boiling benzene in the presence of p-toluenesulphonic acid.  The compounds are used to impart a butter-like flavour to foodstuffs.  The epsilon-keto-acids may be prepared by the following methods:-(1) By hydrogenating the condensation product of a di-alkyl ester of sodium malonic acid and adipic acid anhydride. (2) Condensing a di-ester of sodium malonic acid with an alkyl gamma-halogenated butyrate, condensing the product with an acid halide, hydrogenating, saponifying and acidifying.  (3) Condensing the butyrate of (2) with an alkyl acyl-acetate, saponifying &c. (4) Condensing a dialkyl sodium malonate with a monohalogenated methyl ether, reacting with an alkyl acyl-acetate, saponifying &c. (5) The condensation product of an alkyl-acetyl acetate and an alkyl-gamma-chloro-butyrate is condensed with an acid halide, followed by reaction with ammonia and hydrolysis.  (6) Condensing an adipic alkyl imide with an alkyl magnesium halide, saponifying &c.  (7) Treating a 2-alkylcycloheptanedione with an alkaline solution.  (8) Oxidizing an alkylcyclohexene obtained by dehydrating the alkylcyclohexanol.  (9) Oxydizing an a -alkylcyclohexanone with chromic acid in sulphuric acid.  (10) Replacing the halogen atom in adipic acid mono-alkyl estermonoacid halide with an alkyl group and saponifying &c.  The epsilon-hydroxy acids may be prepared, in addition to the reduction of the keto-acids, by (1) condensing a 1-halogenated-4-hydroxyalkane with a dialkyl sodium malonate to form an epsilon-hydroxyalkyl malonic ester which is saponified and acidified; and (2) subjecting the oxime of an a -alkylcyclohexanone to a Beckmann conversion to form a lactam, hydrolysing to an epsilon-amino-acid and treating with nitrous acid.  The a -alkylcyclohexanone may be prepared as in the example or by transforming a dialkyl pimelate into carbalkoxy-cyclohexanone which is converted via its alkyl derivative and saponification. Specification 748,764, [Group VI], is referred to.

Filed: 1928-07-26
Abstract: 319,103. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 26, 1928. Porous compositions.-Porous building materials are made by mechanically working cold or hot mixtures of hydraulic binding media, water and foam-producing agents comprising sulphonation products of organic compounds containing at least six carbon atoms in the molecule, or salts thereof, and casting the foamy mass in moulds. Examples of foam-producing agents are Turkeyred oil, sulphonation products of tall oil and sulphonic acids of long chain fatty acids such as stearic, oleic and ricinoleic acids, of mineral and tar oils or fractions thereof, and of alkylated aromatic hydrocarbons and salts thereof for instance the sodium salt of an isopropylated naphthalenesulphonic acid. In an example 100 parts of Portland cement and 400 parts of aggregate such as pumice, slag, sand, gravel, sawdust &c., are mixed dry with 0.1 part of the sodium salt of an isopropylated naphthalenesulphonic acid and the mixture is thinned with water, stirred or beaten to a froth and moulded. The foam producing agent may be first worked up into a froth with water and then mixed with the cement and aggregate.
