Title: Artificial phosphor and method of producing it
IPC: C09K11/78
Filed: 1963-02-06
Abstract: A phosphor consists of yttrium oxide activated with trivalent europium oxide.  The concentration of the europium oxide in the yttrium oxide amounts to between 3 and 8, preferably 4, mol. per cent.  The phosphor can be prepared by mixing yttrium oxide, or compounds which produce yttrium oxide on being heated, with trivalent europium oxide or compounds which produce trivalent europium oxide on being heated, and firing the mixture in a closed vessel or in a stream of forming gas consisting of 20% by volume of hydrogen and 80% by volume of nitrogen at a temperature exceeding 1500 DEG  C., preferably between 1600 DEG  C. and 1650 DEG  C.  In a particular example yttrium carbonate is mixed with trivalent europium oxide and fired four times for one hour in a stream of forming gas at about 1630 DEG  C.  In a modification europium carbonate can be used.  A particular phosphor referred to is Y2O3.0.04Eu2O3.  When energized by the mercury resonance line 253.7 mm  the #qmission spectrum shows a narrow-band spectrum in the range from 590 mm  to 710 mm  with a strong maximum at 615 mm .

Abstract: 955,095. Knitting-machines. MATTHEWS & BIRKHAMSHAW Ltd. Feb.13, 1961 [Feb. 12, 1960], No.4975/60. Heading D1C. A straight bar rib machine is provided with points 3, 3<SP>1</SP> which engage the loops on the machine needles 2 and extend them as illustrated in Fig. 8 to enable the frame needles to pass upwardly through them. Thereafter the frame and machine needles go through a knitting motion without taking yarn, the frame needles not being pressed but the machine needles being pressed so that the loops are completely transferred to the frame needles. Plain knitting is then continued on the frame needles only and an adjustment is made to the quality control to enable the plain knitting to simulate the quality of the rib. The points are mounted in two bars 4, 4<SP>1</SP> and are symetrically disposed so that they move in opposite directions to transfer their loops, the two central machine needles having their loops transferred to the same frame needle. To permit this transfer the bars 4, 4<SP>1</SP> are relatively offset to allow for overlapping movements with the result that the loops on the two innermost points are transferred to the same frame needle.

In a vibrating reed type viscometer, a reed 2, Fig. 1, is mounted at the end of a probe 1 which consists of two parts arranged at right angles, the part carrying the probe being surrounded by a tube 4 carrying the liquid under test, the tube having a tapered portion in the vicinity of the probe and generally cylindrical portions extending therefrom. The liquid enters at the larger diameter end of the tube 4 which may be flared, and the annular space 5, between the tapered portion of the tube and a conical casing 3 on the surrounded portion of the probe, may itself reduce in size towards the reed 2, or may be constant in size. Laminar flow of the liquid at the reed is achieved in spite of turbulence at the input of the tube by selecting the dimensions of the tube to give the required Reynolds number.

Title: 6-demethyl-6-deoxytetracycline and the 4-epimers thereof
IPC: C07C/
Filed: 1958-02-18
Abstract: The invention relates to 6-demethyl-6-deoxytetracycline having the formula:  <FORM:0855170/IV(b)/1> the 4-epimer thereof, and salts of these compounds with an acid or a base and complexes with metal salts, e.g. aluminium, magnesium and calcium, e.g. aluminium gluconate.  The base is obtained by catalytically reducing by means of hydrogen a 6-demethyltetracycline of formula: <FORM:0855170/IV(b)/2> wherein Z is hydrogen, chlorine or bromine, or the 4-epimer thereof, in a solvent solution in the presence of a substance which forms a chelate ring with a peri-dioxygenated hydro-naphthalene, e.g. boric acid, boron trihalides such as boron trifluoride, aluminium salts such as aluminium chloride and magnesium salts such as magnesium acetate.  Where Z is hydrogen one mole of hydrogen is used and where Z is chlorine or bromine 2 moles of hydrogen are used.  The reduction is carried out at temperatures of 0 DEG C. to 100 DEG C. and preferably at room temperature to 50 DEG C. and at hydrogen pressures of 1/2 to 100 atmospheres.  The catalyst may be a metal of the platinum family especially 5% palladium hydroxide on charcoal.  Specified solvents are water, dioxane, glacial acetic acid, 2-ethoxyethanol and ethyl acetate; a mixture of water and dimethylformamide (1 : 1) containing perchloric acid is preferred.  The 4-epimer of 6-demethyl-6-deoxytetracycline is produced by allowing a concentrated solution of 6-demethyl-6-deoxytetracycline to stand at pH 3 to 5 and preferably 3,5 to 4,5 for 1 to 7 days.  A suitable solvent is methanol, ethanol, butanol, acetone, 2-ethoxyethanol, 2-methoxypropanol, glacial acetic acid, tetrahydrofuran dimethylformamide and mixtures thereof.  A suitable buffer is sodium dihydrogen phosphate.  Acid salts are prepared by treating the 6-demethyl-6-deoxytetracycline with an acid, e.g. hydrochloric, sulphuric, phosphoric and trichloroacetic at pH below 4.  Alkali metal and alkaline earth metal salts are obtained by treating the 6-demethyl-6-deoxytetracycline with a base such as sodium hydroxide, potassium hydroxide, calcium hydroxide or barium hydroxide at a pH above 6,0.  The free 6-demethyl-6-deoxytetracycline may be obtained by adjusting a solution of the salt to pH 4 to 6. 6-demethyl-6-deoxytetracycline aluminium gluconate complex is produced by mixing 6-demethyl-6-deoxytetracycline with aluminium gluconate in aqueous solution.  6-demethyl-6-deoxytetracycline is a broad spectrum antibiotic more active against staphyloccus aureus than tetracycline and possessing some stability in acid and alkaline aqueous media.  Specification 855,169 is referred to.

With both valves closed, fluid cannot flow between the cylinders of each pair so that both shafts 10, 11 rotate at the same speed. Opening one or other of the valves permits fluid to flow through its passage so that the transmission of power to its associated shaft is reduced or stopped to steer the vehicle. The pistons are provided with seals 19.

Title: Machine for the manufacture of moulded perforated articles
IPC: B28B7/18

Abstract: 866,707. Moulding perforated tiles &c. INSULWOOL PRODUCTS PROPRIETARY Ltd. Feb. 16, 1960 [Feb. 19, 1959], No. 5445/60. Class 87(2). In an apparatus for moulding perforated articles on a series of stripper plates 5 which move intermittently to a moulding position, a mould is constituted by, a stripper plate 5 which fits over a base 1 provided with pins 3 to form the lower moulding surface for the article, a movable flask 11 which can seat on or around the stripper plate to form the mould sides, and an upper plate 18 which forms the upper surface of the mould, the apparatus being provided with a mould filling means 20, means such as a ram 2 to apply pressure to the material, and means to move the stripper plate from the moulding position, after the pins 3 have been withdrawn, so that an adjacent stripper plate will be brought into this position. At this position, shown in Fig. 6, the stripper plate 6 is guided by rollers 22 which are mounted on spring rods. The ram actuated spiked base 1 lifts the stripper plate and the flask 11 until the latter abuts the bridge 16 which can resist the upward movement by means of hooks 25. The flask 11 and the stripper plate 6 are then lowered a small amount and the mould is filled from the hopper 20. The bridge 16, supporting the hopper and the upper mould plate 18, is mounted on rollers, and is subsequently moved by a ram 21 until the mould plate 18 is positioned above the stripper plate. The moulding material is then compressed by means of the ram 2 and the spiked base is subsequently withdrawn, lowering the stripper plate on to the slideway 9, Fig. 6. A pawl 23, Fig. 1, is subsequently lowered to engage between two successive stripper plates so that the hopper 20 and an empty stripper plate can be brought over the moulding position simultaneously by means of the ram 21. In a modification the ram 2 and the spiked base 1 are moved whilst the hopper 20 and the upper mould 18 remain stationary.
