Abstract: 512,512. Dyes. BLOXAM, A. G. (Soc. of Chemical Industry in Basle). Dec. 22, 1937, No. 35500. [Classes 2 (iii) and 15 (ii)] Aminoanthraquinones containing at least once the atomic grouping in which X represents an organic residue containing at least 2 and not more than 7 carbon atoms are acylated in the OH group by treatment with an acylating agent derived from an organic acid containing at most 8 carbon atoms and at least two carbon atoms linked together and containing either at least two carboxyl groups or at least one carboxyl group and a sulphonic group. The products may be used to dye wool or acetate artificial silk blue-green or red tints or to produce pigments, or for dyeing' by the process of Specifications 482,184 or 512,664. The residue "X-OH" may be #-oxyethyl, gamma-oxypropyl, p-oxyphenyl, or an oxybutyl residue, or a hydroxy-acyl residue such as salicyl. Acylating agents may be halides or anhydrides of dicarboxyl acids or halides of sulphocarboxylic acids in which both the sulpho and the carboxy group or only the sulpho or only the carboxy group is in the form of its halide, e.g. the halides of sulphobenzoic, sulphophthalic or sulphoacetic acid. The reaction may be conducted in presence of a tertiary base such as pyridine, and the acidhalide used need not be isolated from the reaction product of the phosphorus halide, e.g. the tri- or pentachloride, and the acid. Also a mixture of the hydroxy-dyestuff and the acid may be treated in a tertiary base with phosphorus tri- or pentachloride. In examples, 4-sulphophthalic anhydride is reacted in pyridine with (1) 1-#-oxyethylaminoanthraquinone, (2) 1.4- or 1.5-di-#-oxyethylamino)-anthraquinone, (3) 1-gamma-oxypropylamino-anthrequinone (4) 1-#-oxyethylamino - 4 - bromanthraquinone, (5) 1.8-di-(#-oxyethylamino)-4.5-dibromanthraquinone, (6) 1-(gamma-chloro-#-oxypropylamino)-4- bromanthraquinone, (7) 1-#-oxyethylamino-4- anilidoanthraquinone, (8) 1-ethanolamino-4- hexahydroanilido-anthraquinone, (9) sulphosuccinic acid anhydride is reacted with 1.4-di- (#-oxyethylamino)-anthraquinone in pyridine, (10) quinolinic acid anhydride is reacted in pyridine with 1.4-di-(#-oxyethylamino)-anthraquinone or with 1-#-oxyethylamino-4-(4<1>-#- oxyethylamino) - phenylamino - anthraquinone, (11) benzoic acid m-sulphochloride is reacted in pyridine with 1.4-di-p-oxyphenylamino-anthraquinone. Specifications 480,358 and 506,526 also are referred to. 1-#-Oxyethylamino - 4 - (4<1> - #-oxyethylamino)- phenylamino-anthraquinone is obtained by the action of ethylene oxide on 1-amino-4-(4<1>- amino -phenylaminoantbraquinone

Title: Pressure devices for delivering liquids
IPC: F04F1/06
Filed: 1929-11-23
Abstract: 343,192. Delivering liquids. DEAN, G., 163, Cole Valley Road, Hall Green, Birmingham. Nov. 23, 1929, No. 35928. [Classes 102 (i) and 102 (ii).] In an oil or like liquid delivery system a delivery pump is placed near a service container which is arranged to communicate with a distant main tank and also from its lower end with the pump inlet. Means under valve control are associated with the pump whereby positive pressure can be applied to the tank and negative pressure to the service container. A service tank 17 is connected at the bottom by a pipe 11 with a liquid level device 4 which in turn is coupled by a pipe line 2 with a distant main storage tank 1. The tank 17 is also coupled by a pipe 37 with a delivery pump 35. The normal level 18 in the service container 17 is determined by a float 19 which is coupled to a valve 20 and opens or closes the container to atmosphere. The valve 20 is hollow, and holes 22 and a central passage form the connecting way from the atmosphere to the tank. The arm of the float is continued to engage and to actuate a second valve 24 which is coupled to a pipe line 25 so that a suction or negative pressure can be applied to the container to assist in inducing the flow from the main tank to the service tank. This action is controlled by a hand-actuated three-way valve 38 which can also be positioned so that it is possible to connect the pipe lines 12 with a valve gear on top of the main tank or on top of the float chamber so as to provide a positive pressure above the liquid in the main storage tank should such be required. When it is required to draw a quantity of liquid from the service tank the valve 38 is turned so as to cut off the air lines, and the valve 36 is turned so as to open up the supply pipe 37. Actuation of the piston 34 then results in liquid being drawn up to the pump 35 and ultimately being forced out through a delivery opening 41. The pump may be associated with a number of subsidiary chambers carrying different grades of lubricating oil. The subsidiary chambers may be grouped in the manner indicated in Specification 321,497, [Class 102 (i), Pumps &c.].

Patent GB-1124303-A (GB)
Title: Method for producing a transversely elastic fabric
IPC: D03D15/56
Filed: 1965-08-23
Abstract: A transversely elastic fabric is produced by dry spinning a yarn from a cellulose acetate solution at a temperature of from 40-45 DEG C, slowly extracting solvent from the yarn in a slow air stream, weaving a fabric incorporating such yarn in the weft, subjecting the fabric to a moist heat treatment and thereafter to a finishing treatment, all such treatments being carried out without tension.  The woven fabric is de-sized and is embossed at a temperature of 120-130 DEG C at a pressure of 4-7 tons per metre working width for a contact period of not less than 10 seconds before or after the moist heat treatment which is carried out by hot water at a temperature of 95-98 DEG C or by steam for a period of up to one hour.  The embossing rollers may be provided with a dot or crepe pattern and a counter pattern.  The fabric is heat set in a slack condition on a stenter at a temperature of 170-200 DEG C for a period of 20-30 seconds and is finished in steam at a pressure of 1.8-2.5 atmospheres for a period of 3-5 minutes.  The fabric may be dyed and heat treated for fixing the dye either before or after the moist heat treatment.  The moist heat treatment may be preceded by a swelling treatment effected by immersing the fabric in a 2-5% solution of acetone at room temperature for a period of 2 hours or a 10% solution of calcium chloride, zinc chloride or magnesium chloride at room temperature for 2-4 hours.  Examples disclose the treatment of a woven fabric having a secondary cellulose acetate weft yarn as specified above and a cellulose acetate warp yarn.

Patent GB-1192398-A (GB)
Title: Relief Moulding of Fibrous Pulp Webs
Inventor: HANKE KARL
IPC: D21J1/00
Filed: 1967-08-07
Abstract: 1,192,398. Embossing. K. HANKE. 7 Aug., 1967, No. 36203/67. Heading B6J. [Also in Divisions B8, D1 and D2] A web of fibrous pulp, still wet from a production process, is relief-moulded, by feeding it between a moving mould and an elastically flexible moving countermould. The surface of the countermould is a two-phase material comprising a matrix and inclusions of a substance more flexible than the matrix, each zone of included substance being separated from the others by the matrix. As shown, a web 1 of paper pulp, still wet from previous processing, is fed on to a roller 3a on which it lies slack and carried through the nip of this roller and another roller 4a. The surface of the roller 4a is of elastieally flexible material, e.g. neoprene, containing gas-filled pores. This surface is cut to leave sharp pore edges and so has a higher coefficient of friction than the surface of the mould. The moulding may be carried out in stages, the flexibility of the countermould decreasing from stage to stage. In Fig. 2 (not shown), the web is fed to the moulding machine by a conveyer belt (2), and a feeler device (15) resting on the web between the conveyer and the moulding machine controls the speed of the latter, and so the tension of the web. Three rollers 4a, 5a and 6a press on to the mould roller 3a, the first two being countermould rollers as shown in Fig. 2, and the last having a smooth and solid surface to smooth and compact the upper surface of the moulded web. These three rollers are all driven by contact with the mould roller. The web is heated by a jet of steam just before the first moulding stage, and a lubricant, e.g. water containing dissolved resin, is sprayed on at this stage. A suction device removes excess water expelled by the moulds. The web leaves the moulding machine by another conveyer, which feeds it to a dryer free of tension by means of a deflector (17) which is caused to oscillate about an axis (18) by a cam (19). This lays the web in small waves on the conveyer belt of the dryer to compensate for shrinkage. In another embodiment (Fig. 1, not shown), the mould and countermoulds are all endless belts.

Title: Improvements in or relating to planting machines
IPC: A01C11/02
Filed: 1929-11-26
Abstract: 344,349. Planting-machines. POMIERANIEC, I., 4, Eden Mansions, Gondar Gardens, Kilburn, London. Nov. 26, 1929, No. 36227. [Class 6 (i).] A plant-setting machine comprises a conveyer on which the plants are fed, and a series of devices for carrying the plants from the conveyer to the soil, the arrangement being such that the carrying devices are travelling at substantially the same speed and in substantially the same direction as the conveyer when the plants are transferred to them. The devices for carrying the plants to the soil may be mounted on an endless band k, Fig. 1, running over rollers r, r<1>. There may be one or more conveyers and each may comprise an endless band k<1> driven at the same speed as the band k and composed of articulated elements or links c, Fig. 2, forming platforms having walls along their front and rear edges. The forward roller supporting the conveyer is arranged somewhat to the rear of the roller r and is of smaller diameter, as described in Specification 333,614, [Class 6 (i), Cultivating implements &c.]. The band k consists of links or sections hinged together and each having rigidly connected to it an arm f carrying a laterally projecting arm e. The arms f are mounted tangentially to the band k so as normally to lie on one another but to separate as they pass round the rollers r, r<1>. A pin or jaw d carried by an arm d<1> co-operates with an upright pin z on the arm e to grip a plant. The arm d<1> pivots about an inclined or vertical pivot a and is moved into gripping position by the engagement of an extension h with a fixed cam x. The plants are placed across the conveyer k<1>, with the leaf portion overhanging a step on the link c. As the band k<1> turns downward round its front supporting roller the arm d<1> swings about its pivot and the plant is lightly gripped between the pins d, z and is turned through a right angle, being then separated more from the following plant and carried down to the soil with its root lowermost. It is deposited in a hole or in a furrow made by a share on the machine, and the soil is pressed down on the root by the wheels. Gravity, spring, or other means may be provided for releasing the plant by returning the arm d<1> to its normal position when the extension h leaves the cam x. In a modification the band k passes round three rollers. In another the arms f are at right angles to the band k and push the gripping-devices along an inclined rail. In the arrangement shown in Fig. 6 the arms e, d<1> are of equal length, the arms d<1> being provided with extensions h engaging a cam x and the arms e with projections engaging a guide. In another modification the conveyer consists of rods mounted on cranks on two crank shafts. According to the Provisional Specification the plant grippers may be carried by rotatable members instead of an endless band, and they may comprise platforms provided with walls with which walls on pivoted members co-operate, the plants being placed across the band carrying the grippers as well as across the conveyer band.
