Title: Manufacture of sugar
IPC: C13B20/14
Filed: 1942-02-11
Abstract: 557,690. Purifying sugar juices. DORR CO., Inc. Feb. 11, 1942, No. 1824. Convention date, Jan. 31, 1941. [Class 127] Sugar juices, raw sugar solutions or dextrose solutions prepared from corn starch are purified by removal of ionic impurities by treatment first with an organic cation-exchange material and then with an organic anion-exchange material. Colloidal matter and colouring substance are also separated by passage through the exchange material. The juices may be preliminarily treated to remove coagulable matters by liming, heating, carbonating, clarifying and filtering and in the case of beet juice treatment with sulphur dioxide. The sugar solution is passed upwards through the exchange material which is regenerated by washing out the sugar by downward now of water followed by an upward flow to loosen the exchange material and remove impurities collected in it, and the regenerating solution may be passed upwards or downwards. Batteries of three or four vessels containing exchange material. are provided with pipe connections and valves so that one or more may be regenerated while the others are in use. Each vessel is provided with a pH indicator to show the degree of exhaustion of the bed, consisting of a bowl 191 carrying electrodes 192, 193 and supplied with juice or other liquid by a pipe 190 from the outlet pipe 189 of the exchange vessel 188a. Overflow from the bowl 191 is pumped back to the top of the vessel. As cation-exchange materials may be used those produced by treating lignite with concentrated sulphuric acid, by treating aromatic phenolic bodies such as tannin, with sulphuric acid, petroleum acid sludge, fuming sulphuric acid &c. or by condensation of aromatic phenols with aldehyde with or without subsequent introduction of acid sulphur groups. As anion-exchange materials may be used those produced by condensation of an aromatic amine which may be mixed with a mono- or di-saccharide with an aldehyde or those in which the active constituent is a basic dye stuff such as aniline black. Specifications 450,308, 450,309, [both in Group IV] and 633,385 are referred to.

Filed: 1947-01-22
Abstract: 629,004. Sewing-machines. AUSTLID, A. Jan. 22, 1947, No. 1982. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 23, 1947.] [Class 112] Feed, reversing and regulating. In a sewing-machine, particularly for buttonhole sewing, in which the position of the feed-control lever is determined by an adjustable screw thereon forming a stop to engage the machine frame, fine adjustment is obtained in the range of short stitches by forming the frame with a recess with inclined faces for engagement by the screw. The screw may be so mounted on the lever that it can be swung to an out-of-use position to allow a quick change to longer stitches and back to the same length of short stitches. In the form shown the feed-control lever 2 is pivoted so as to swing in the plane of the paper, its swing being limited, to determine its position of adjustment in either direction of feed, by engagement of the point of a screw 5, carried by the lever, with a part of the machine frame 4, and fine adjustment of the length of short stitches is obtained by making a recess in the frame, with inclined sides 12 with which the point of the screw 5 engages. In order to allow a quick change to longer stitches without disturbing the adjustment for short stitches the screw 5 is mounted in a block 8 pivoted to the lever 2, so that it can be swung clear of the recess ; a lug 10 on the lever prevents this swinging in one direction.

Title: Manufacture and use of polymerization inhibitors
IPC: C07C17/42
Filed: 1948-01-26
Abstract: Compounds of the general formula <FORM:0652992/IV (b)/1> (wherein R1-R5 represent hydrogen, hydroxy or substituted or unsubstituted hydrocarbon groups, provided that at least one of R1 and R3 must be hydroxy) are rendered more effective as inhibitors of the polymerization of vinyl aromatic compounds by heating them with a small amount (e.g. a catalytic amount), of stannic chloride, e.g. by refluxing in the presence of a solvent, the products may be used, individually or in admixture or in conjunction with other inhibitors, for inhibiting the polymerization of styrene, a -alkylstyrenes, nuclear alkylated styrenes, chlorostyrenes (especially nuclear dichlorostyrenes), divinylbenzene, and mono-and poly-vinyl-naphthalenes and -chloronaphthalenes.  Examples describe the treatment of: (1) 2 : 5-di-tert.-butylhydroquinone; (2) a mixture of dibenzylhydroquinones (obtained by refluxing hydroquinone with benzyl chloride in the presence of ferric chloride) and di-tert.-butylcatechol (obtained similarly from catechol and tert.-butyl chloride); (3) 4-mono-tert.-butylcatechol (similarly prepared); (4) catechol.  Additional starting materials specified are hydroquinone, pyrogallol, 4 : 6-di-tert.-butylpyrogallol, 4 : 5 - diamylcatechol, dichlorophenylethylhydroquinone and 2-tert.-butyl-5-dichlorophenylethylhydroquinone (obtained by condensing mixed chloroethyldichlorobenzenes with hydroquinone and tert.-butylhydroquinone respectively), 2 - phenyl - 5 - butylhydroquinone, 5-octyl-4-ethylcatechol, tributylhydroquinone, 2 : 3 - di - tert. - butyl - 6 - phenylhydroquinone and 2 : 5-di-p-tolylhydroquinone.  The Specification as open to inspection under Sect. 91 comprises also a reference to the treatment of di-tert.-butylchlorohydroquinone.  This subject-matter does not appear in the Specification as accepted.ALSO:Vinyl aromatic compounds, e.g. styrene, a -alkylstyrenes, nuclear alkylated styrenes, chlorostyrenes (especially nuclear dichlorostyrenes), divinyl benzene, and mono- and poly-vinylnaphthalenes and -chloronaphthalenes, are stabilized during distillation by the addition of a polymerization inhibitor obtained by heating a compound of the general formula <FORM:0652992/III/1> (wherein R1-R5 represent hydrogen, hydroxy or substituted or unsubstituted hydrocarbon groups, provided that at least one of R1 and R3 must be hydroxy) with a small amount (e.g. a catalytic amount) of stannic chloride.  The inhibitors may be used individually or in admixture or in conjunction with other inhibitors, it being advantageous to use one inhibitor which is substantially less volatile together with one which is slightly more volatile than the monomer being distilled.

Title: Radio-active gaseous gauging source
IPC: G21G4/06
Filed: 1957-01-22
Abstract: 815,401. Sources of radio active radiation. FOXBORO CO. Jan. 22, 1957 [Jan. 26, 1956], No. 2317/57. Class 98(1) A chamber, filled with radio active gas, has part of its walls contributed as a window permeable to the radiation emitted by the gas, the remaining part of the walls being substantially opaque to the rays. The gas may be krypton 85, and the radiation source may be used in apparatus for gauging the thickness or weight of material. As shown in Fig. 2, the tube is plugged at both ends by plugs 20, 21, and is provided with a tube 22 by which it may be filled with krypton 85. The tube, which is permeable to the radiation emitted by the gas, may be mounted in a shielding holder 25, Fig. 4, with mounting lugs 26. The assembled source 24 may be mounted on a support member 31, Fig. 6, mounted for rotation within a cylindrical shielding housing 27, with a radiation permeable window 29. The housing 27 may have mounting feet 28, and the movement of the support 31 is checked in a shielded and an unshielded position by a screw 37 engaging recesses 35, 36 in the support 31. If desired, two sources 24 may be mounted side by side of the support 31. The opening 30 for the window 29 may be closed by a sliding shutter, Where the ray source is required to be of smaller volume, the gas may be introduced into a recess formed in a cup 44, Fig. 11, and closed by a window 45 through a filler pipe 46. Alternatively, the cup may be filled from below, and the window may be corrugated so as to move on change of pressure. A method of filling an elongated chamber is shown in Fig. 16. The filler tube 22 is connected by way of a valve 49 first to a vacuum pump 48, and afterwards to a source of gas 47. The radiation may be measured, and when it reaches a desired intensity, the tube 22 is pinched off at 22<SP>1</SP>. If too much gas is supplied, the supply 47 may be cooled down to draw some of the gas back from the chamber. Alternatively, the tube' may be connected to a flexible bellows filled with the gas. A method of filling a number of sources at once is also described.
