Patent GB-872995-A (GB)
Title: Process for purifying silicon or a ferro-silicon alloy
IPC: C01B33/025
Filed: 1957-11-04
Abstract: Molten silicon or ferro-silicon of more than 95% purity is purified by intimate contact with an oxygen-containing gas, optionally in the presence of a flux, e.g. an alkali metal salt. Titanium, iron, aluminium, calcium, and carbon may thereby be oxidised.  The oxidised metal impurities may be removed as a surface slag.  Purification may be effected by bubbling air or oxygen through the molten silicon from a graphite tube, or by directing a flame produced by burning oil in an excess of air into a vessel being filled with molten silicon from a production furnace (the Figure, not shown).

Title: Improvements in or relating to ampoules
IPC: B65D81/32
Filed: 1929-11-11
Abstract: 343,075. Ampoules. MENZIES, J., Clayton Works, Little East Place, Kenning- ton, London. Nov. 11, 1929, No. 34427. [Class 81 (i).] Double ampoules, of the kind comprising two glass containers separated by a fragile partition, are made by separately forming the two containers and then fusing them together so that part of one container forms an easily breakable partition between the containers but does not extend to a substantial extent within the other container. The container A<1> is formed with a neck portion a<1> drawn out to a thin-walled point a2. The neck a<1> is inserted in the open tubular end a<5> of the container A and the two parts are heated to form a, fused joint. After removal of the neck portion a<3> of the container A, the point a2 may be broken by means of a glass rod or closed tube B, previously enclosed in the container A, to allow the liquid in the container A to enter the container A<1>, which may have been exhausted before sealing, or formed with a drawn out point a<6>, Fig. 3, adapted to be broken, to facilitate flow of the liquid. The glass rod B may be replaced by a heavy glass ball adapted to break the point a<2> on being shaken, thus obviating the need to open the container A before causing the contents of the two containers to mix. One or both of the containers may be made of coloured glass.

Abstract: 968,609. Cooking in fat &c. DCA FOOD INDUSTRIES Inc. Sept. 26, 1961 [Aug. 28, 1961], No. 34445/61. Heading A4D. In an apparatus for frying doughnuts, cakes &c., a doughnut forming device 78 sliding on a track 76 discharges doughnuts into a tray 51 immersed in hot fat in a tank 11 and after partial trying the tray is tilted up and over by a handle 60 to discharge the doughnuts into a grid-tray 39, also in the tank, where frying is completed. The tray 39 is then tilted up and over by a handle 50 and the doughnuts discharged on to a draining grid-tray 119, fat running down a sloping pan 129 therebeneath back into the tank. Grid-tray 117 is then tilted up and over by a handle 122 and the doughnuts dumped on to a gridtray 132 in a glazing receptacle 123 and removed therefrom by operating a handle 138 which lifts up the tray 132 and locks it in an upward and forwardly inclined draining position for subsequent removal of the finished doughnuts. When frying cakes, these are placed on a tray 98 which is fixed in position on a flat panel 86 which is tilted by a handle 97 to slide the cakes into tray 51. When the latter is emptied more doughnuts or cakes may be fed into it so that at any one time each tray may contain doughnuts in a different stage of preparation. Each of the trays is fully separable from the apparatus by disengagement of the ends of the rods 84, 58, 40, 118, 133 defining the pivot axes of the trays. Trays 86, 51, 39 are journalled between grooved brackets 19, 20 supported by and dependent from the side edges of the tank, and trays 117, 132 are journalled between brackets extending forwardly from the front wall of the tank. The fat in the tank is heated by an element 65 connected to a control box 69 located on a support bracket 70 resting on the tank edge, by legs 67 passing between brackets 70 and 20.

An internal shoe-drum brake comprises a plurality of wedge-shaped members pivoted at their broad ends to links which are pivoted to arcuate levers displaceably secured to a backplate, on braking the levers are forced apart to bring the wedge-shaped members into contact with the drum so that friction forces them between the drum and stops secured to the backplate. Arcuate levers 5, pivoted at 8 to backplate 1, carry links 4 to which wedge members 3 are pivoted, the links 4 being biased by springs 7 to maintain the members 3 in contact with stops 6 fixed to back-plate 1. On braking, the levers 5 are separated by an hydraulic motor 10 or mechanically by a Bowden cable 11, to bring members 3 into contact with a brake drum, friction then moving, and firmly wedging, the members 3 between the stops 6 and the brake drum. Similar wedge members 13 face in the opposite direction to members 3 for braking on reverse rotation of the drum. The wedgeshaped members may be used to brake a linearly moved plane surface.

Title: Nozzle for producing an intermittent jet of gas or liquid
IPC: B05B1/08
Filed: 1947-12-30
Abstract: 631,653. Sprayproducers. BROUSSARD, G. L. Dec. 30, 1947, Nos. 34580 and 34581. Convention dates, Dec. 3, 1945 and May 27, 1946. [Class 69 (iii)] A nozzle for fluid under pressure has means actuated by the fluid for interrupting periodically the fluid outlet flow to produce an intermittent jet. In one embodiment, Fig. 1, air entering a nozzle 1 at 2b passes through an orifice 6 into a chamber 3 when a valve 2 is held by the hand in the lowered position. An oval-shaped metal rotor 5 is forced by the air to rotate anti-clockwise within the chamber 3, thereby closing alternately the inlet orifice 6 and the outlet orifice 8 to produce an intermittent jet. A shallow groove 7 in the chamber wall facilitates rotor motion from its initial position. A nozzle for liquid, Fig. 3, has a circular rotor, and liquid passes into a chamber 3 via a valve 6a and a passage 6. Fig. 4 shows a liquid nozzle which can give an intermittent or continuous jet depending on the position of a three-way cock 11. A further embodiment, similar to Fig. 3, is described, wherein a tubular portion is formed on the chamber wall and contains a finger portion which may be inserted within the chamber 3 to stop the rotor and thereby effect a change-over to a continuous jet.

When the latter is removed, insert 18 is retained by releasable latch springs (25), 26 engaging a flange 24. When a negative of different size is to be used, insert 18 is removed and replaced by a similar insert having a different condenser, suitable for the new negative size.

Abstract: An antifungal antibiotic designated NC 1968, is obtained from the mycelium formed on fermentation of Streptomyces coelicolor var. aminophilus NRRL 2390 nov. spec. in an aqueous nutrient medium under aerobic conditions of submerged or surface growth. The medium contains a source of (a) carbon, e.g. starch, dextrin, glucose, maltose, inulin, ribose, levulose, galastose, glycerol, mannitol and cellobiose, (b) organic nitrogen (inorganic nitrogen is not utilized) e.g. beef extract, yeast extract and peptone, and (e) mineral salts, e.g. sodium chloride, potassium dihydrogen phosphate and potassium monohydrogen phosphate.  Temperature of cultivation is 15 DEG  to 40 DEG  C. and preferably 20 DEG  C., duration is 10 days.  The <PICT:0828792/IV (b)/1> and <PICT:0828792/IV (b)/2> broth is filtered, the mycelium washed to remove water-solubles and then extracted several times with an alcohol especially methanol, preferably after rupturing the cells of the mycelium. The mycelium may be agitated with the methanol for several hours at room temperature, filtered, filtrate evaporated, the residue taken up in water and lyophilized.  Further purification is by chromatographic absorption.  The crude antibiotic is placed in a column packed with wood pulp cellulose and is resolved with a mixture of propanol, water, benzene and glacial acetic acid and the active fractions collected.  Antibiotic NC1968 is a yellow amorphous substance soluble in pyridine and dimethylformamide; soluble (with the addition of a little water) in methanol, ethanol, propanol, butanol, acetone and dioxan; practically insoluble in water, carbon tetrachloride, ethyl acetate, methyl isobutyl ketone, ether, benzene and hexane; contains 64.70% carbon, 7.93% hydrogen, and 2.46% nitrogen; in 70% aqueous n-propanol system has an Rf value of 0.8 to 0.9, and exhibits an infra-red absorption spectrum as shown in Fig. 1 and an ultra-violet absorption spectrum as shown in Fig. 2.  It is distinguished from the antifungal antibiotics ascosin, candicidin and trichomycin.
