Title: Process for isolating tetracycline in crystalline form
Inventor: SVANHOLM GERT
IPC: C07C233/00
Filed: 1964-06-15
Abstract: Crystalline tetracycline substantially free from chlortetracycline is isolated from an aqueous tetracycline solution containing at least 5000 tetracycline units per millilitre and substantially free from calcium ions and other metal ions capable of forming complexes with tetracycline, by adding to the said solution an organic solvent which is immiscible or only slightly miscible with water and a di- or monoester of ortho-phosphoric acid or phosphorous acid soluble in said solvent, adjusting to pH 3 to 8 before or after adding the organic solvent and separating the precipitated tetracycline, The calcium and other metals ions may have been removed by ion exchange or precipitation or may be kept in complex form by the addition of a chelating agent having a stronger chelate-forming effect on said metal ions than has tetracycline, e.g. ethylene diamine tetra-acetic acid. Typical esters are di-(2-ethylhexyl)-ortho phosphoric acid, di-nonyl-ortho-phosphoric acid and monoester of decyl phosphite. Butyl acetate, chloroform, amyl alcohol and methyl isobutyl ketone are suitable organic solvents.  The precipitated tetracycline may then be converted to a salt e.g. the hydrochloride.

Patent GB-800705-A (GB)
Title: Liquid detergent compositions
IPC: C11D3/37
Filed: 1956-08-14
Abstract: A liquid detergent composition comprises a concentrated pourable substantially homogeneous suspension containing 0.1-2 parts by weight of an organic synthetic detergent to each part of a water-soluble inorganic polyphosphate.  The detergent, which is usually present in amounts of 5-15 per cent, may be either anionic, such as the sulphate esters of polyhydric alcohols incompletely esterified with higher fatty acids, the higher fatty esters of low molecular weight alkylol-sulphonic acids, the higher fatty acid ethanolamide sulphates, and the higher fatty acid amides of aminoalkylsulphonic acids, or non-ionic, such as ethylene oxide condensates with higher fatty acid alkanolamides, with higher fatty acids or alcohols, with tall oil acids, or with higher alkyl mercaptans or amides.  The preferred detergents, however, are the higher alkylaryl sulphonates such as dodecylbenzene sulphonate or the higher alkyl sulphates such as lauryl sulphate where the detergent is present as the sodium, potassium, ammonium, isopropanolamine, or mono- or tri-ethanolamine salt and contains 8-15 carbon atoms in the alkyl group, and the condensation products of ethylene oxide with alkyl phenols or with polypropylene glycols.  The polyphosphate, which is generally present in an amount of 15-45 per cent, may suitably be either the sodium or potassium pyrophosphate or tripolyphosphate, and is suitably a mixture of sodium and potassium tripolyphosphates in the range of 5:1 to 2:1 by weight. An acid tripolyphosphate may also be used.  Any suitable liquid medium may be employed, but it is preferred to use an aqueous medium such as water or an aqueous solution of a lower aliphatic alcohol such as ethanol, isopropanol, or propanol, to yield a solids content of at least about 40 per cent, and preferably 50-75 per cent, by weight so that a permanently non-caking suspension is formed.  Hydrotropic dispersing agents, for example the water-soluble lower alkylaryl sulphonates or naphthalene formaldehyde sulphonate, are preferably included in the compositions in amounts of 4-12 per cent.  Anti-redeposition agents such as the cellulose ethers, starch derivatives or polyvinyl pyrrolidone, but most suitably sodium carboxymethylcellulose, are generally incorporated in amounts of 0.25-5 per cent, and foam improvers such as higher fatty acid ethanolamides are customarily also included in amounts of 2-15 per cent.  Other fatty acid amides, perfumes, colouring matter, corrosion and tarnish inhibitors, germicides, bleaching agents, optical bleaches and fluorescent dyes may also be added in minor amounts.
Patent GB-599972-A (GB)
Title: Improvements in production of metal hydrides
IPC: C01B6/00
Filed: 1945-09-25
Abstract: Metal hydrides are obtained by heating a loose mixture of a hydride-forming metal compound, e.g., calcium, strontium or barium oxide, and aluminium in a reaction zone to a temperature <PICT:0599972/III/1> above the melting point but below the boiling point of aluminium, removing the refractory coating of aluminium oxide at least in part from the molten globules of aluminium in the charge, bringing unoxidised molten aluminium into contact with the metal compound, distilling the resulting reduced metal, condensing the distilled metal in a cooler part of the reaction zone, and then admitting hydrogen to convert the condensed metal to its hydride. The aluminium oxide coating may be removed by placing the heated charge under vacuum to expand the molten aluminium by heating the charge in the presence of a flux such as calcium or sodium fluoride, or by mixing and grinding the charge during the reaction.  A reaction vessel 10 is indirectly pre-heated by hot gases entering through a conduit 13, evacuated by a vacuum pump attached to conduit 29 and filled with an inert gas such as helium or argon through a valve 51. A charge of calcium oxide and aluminium is introduced through a trap 27, the temperature being raised by the heating gases to 950 DEG C. During the metal-forming reaction, a rotating mechanical mixing device 31 provided with opposing lateral arms 36, 37, depending oscillating supports 38, 39 and heavy blocks 42 close to the bottom of the reaction vessel mix and grind the charge.  The reduced calcium distills and is condensed as a ring at 55.  Hydrogen is then admitted through a valve 20 to convert the calcium to calcium hydride which is allowed to cool in a non-oxidising atmosphere before removal through the cover 15. p
Patent GB-481801-A (GB)
Title: Improvements in and relating to adding machines having multiple-zero keys
IPC: G06C7/10
Filed: 1936-09-14
Abstract: 481,801. Calculating - machines. TRIGGS, W. W. (Underwood Elliott Fisher Co.) Sept. 14, 1936, No. 24987. [Class 106 (i)] An adding-machine of the single-bank type has one or more multiple-zero keys, the depression of any one of which causes the repeated action of the setting mechanism to set a succession of zeros. The depression of a numeral key 49, Fig. 1, or of the single-zero key 49a, rocks a lever 52 connected by a link 53 to a lever 54, Fig. 2, pivoted at 55 and connected to a rod 65 slidable in a post 64, carried on a swinging frame 62 pivoted at 63. The rod 65 pushes out a corresponding stop 42 in a bank of stops carried in a stationary frame. A universal vertical bail 59 is engaged by any operated lever 54 and rocks a lever 58 connected to a rod 65a which thus swings a rack 69 against the action of a spring 71 and allows the post 64 to escape past a tooth of the rack so that the frame 62 can move a half-step clockwise under the action of its spring 68. The further movement is temporarily prevented by the engagement of the protruding end of the rod 65a with the rack tooth and the step of movement is completed when this rod is withdrawn. The set stops 42 limit the rise of rods 46 carried by members 45 hinged to type bars 3 which also actuate the totalizer 125. The rods 46 slide in a carriage 47 linked to the frame 62 to be moved thereby. The denominational position of the carriage 47 is indicated by a pointer 72 and scale 73. Multiple-zero keys and mechanism. Four multiple-zero keys 84 .. 87, Fig. 6, are provided. The depression of any multiple-zero key rocks a shaft 94 by a connection 92, 93, a pawl 81 on this shaft thus releasing a ratchet wheel 82 secured to a shaft 75 which is then driven clockwise by a spring 74 until a peg 95 in the shaft engages the end of a slot 98 in the hub of a ratchet wheel 90 free on the shaft 75. The ratchet wheel 90 is at this time locked by an arm 89 of the depressed keystem. There is a ratchet wheel 90 for each multiplezero key but the length of the slot 98 is different in the hub of each ratchet wheel being smallest in the case of the 00 key and largest in that of the 00000 key. The shaft thus rotates through an angle corresponding to the number of zeros on the depressed key. A toothed wheel 76 secured to the shaft 75 oscillates an escapement-like lever 77 bearing on the link 53 normally operated by the single-zero key, the link being reciprocated a number of times equal to the number of zeros on the depressed key, this number of zeros being thus set in the stop bank 42. When the depressed key is released a spring 91 secured to the ratchet wheel 90 and to the shaft 75 rotates the ratchet wheel 90 until the other end of the slot 98 engages the peg 95. The shaft 75 is restored anticlockwise and the spring 74 rewound by gearing 104, 105 driven by a link 100 from the main shaft. The wheel 76 is locked against backward motion by a detent (not shown) and is connected to the shaft 75 by a one-way coupling 108.

Title: Improvements relating to sewing machines
Inventor: MERRELL GEORGE LEONARD
IPC: D05B3/18
Filed: 1959-07-22
Abstract: 886,359. Sewing machines. STEELS & BUSKS Ltd. July 15, 1960 [July 22, 1959], No. 25135/59. Class 112 A sewing machine adapted to sew fastener tapes to garments comprises an element adapted to detect the presence of a fastener member at a position relative to the point of entry of the needle, a micro switch operable by said element when the latter meets a fastener member, and a solenoid controlled by said switch and operatively associated with the needle bar, the arrangement being such that on energization of the solenoid the needle bar, or a needle-carrying part thereof, is shifted to a position in which the needle in its next descending stroke will miss the fastener member. The machine sews on to garments a tape 1 carrying spaced fastener members 2. A finger 3, pivoted to one arm of a bell crank lever 4 pivoted at 5 to a fixed bracket 6, has a nose 9 biased by a spring 8 into engagement with the work beneath the needle 35. The latter is carried by a block 37 pivoted to a block 38 rigid with the needle bar 22. Bell crank lever 4 is pivotally connected by a link 10 to one end of a bar 11, the other end of which rests on an adjustable screw 16 carried by a bar 17 which rests on a rod 20 connected to the block 37. One end of bar 11 is thus raised each time the needle bar rises and the other end is raised, via the linkage 3, 4, 10, each time nose 9 rides over a fastener member 2. If the latter end is so raised when the needle bar is at its highest position, a flange 12 on bar 11 engages a leaf 13 to close a micro switch 14 to energize a solenoid 30. Bar 11 is held momentarily in its fully raised position by the engagement of a flange 26 thereon with a notch 25 in a bell crank lever 23 which rocks respectively anti-clockwise and clockwise, as link 10 rises and falls, under the influence thereon of a spring 27 and of a stud 28 on link 10. The armature 31 of solenoid 30 is pivoted to one arm 32 of a bell crank lever, the other arm 33 of which abuts a roller 34 on block. A spring 39, interposed between blocks 37 and 38, holds roller 34 against arm 34. When solenoid 30 is energized, arm 33 thereby swings block 37 clockwise to move needle 35 against the direction D of feed to a position 35<SP>1</SP>, whereby the needle avoids the fastener member on its next descent. A second needle 40 is carried on the fixed block 38.
