Filed: 1958-07-04
Abstract: <PICT:0876639/IV (b)/1> <PICT:0876639/IV (b)/2> A new antibiotic, antifongine 4915, is obtained by extraction from the mycelium or culture broth residue after removal of antibiotic 4915, prepared by cultivating Streptomyces paucisporogenes (ATCC 12596; NCIB 8790) or a mutant thereof in accordance with Specification 826,756.  The dry mycelium may be extracted by means of methanol or ethanol containing 10% calcium chloride.  Crude antifongine is precipitated by adding water and removing the solvent from the extract.  After removal of antibiotic 4915, the broth residue is extracted with methanol or ethanol, water is added to the extract and then n-butanol.  The n-butanol extract is concentrated, filtered and crude antifongine precipitated by the addition of acetone-petroleum ether (1:2). The precipitate may be dissolved in aqueous methanol and passed through a column of a sulphonic cation exchange resin, e.g. "Amberlite" (Registered Trade Mark) 1R120 (acid form) and then through an anion exchange resin Amberlite 1R4B (OH form), the percolate, concentrated, taken up with C-butanol and the solvent removed.  Further purification may be obtained by adsorption on activated alumina and elution with dioxane-water-butyl acetate containing 5% acetic acid. It may also be crystallised from pyridine-dioxane-waterbutyl acetate. Antifongine 4915 is a yellow powder decomposing at 100 DEG C.; it is sparingly soluble in water, hydrocarbons, ketones, chlorinated solvents, alcohols up to 3 carbon atoms and carbon disulphide; it is soluble in propylene glycol, isoquinoline, pyridine, triethylamine and dimethylformamide; it contains C=63.6%, H=7.8%, N=2.8% and oxygen (balance); it gives a blue or green in concentrated acids, turning to yellow on dilution with water; the ultra-violet absorption spectrum in acetic methanol (Fig. 1) shows maxima at <FORM:0876639/IV (b)/1> ; <FORM:0876639/IV (b)/2> ; <FORM:0876639/IV (b)/3> ; <FORM:0876639/IV (b)/4> and <FORM:0876639/IV (b)/5> ; infra-red absorption spectrum (Fig. 2) shows maxima at 3.1, 5.86, 6.15, 6.27, 6.4, 8.5, 8.84, 9.0, 9.32, 9.6, 10, 11.24, 11.28, 12.60, 12.98 and 13.2 microns.  It is active against a wide range of fungi and may be used in human and veterinary medicines to combat mycosis and also in agricultural compositions (see Group VI).ALSO:A fungicidal composition comprises the antibiotic antifongine 4915 (see Group IV (b)) and an inert carrier.  A powder is produced by incorporating an ethanol solution of antifongine 4915 and 2,6-di-tert-butyl-p-cresol in calcium carbonate, talcum, clay or colloidal silica and removing the solvent. An emulsifiable concentrate is obtained by mixing antifongine 4915, ethoxyethanol, calcium chloride, 2,6-di-(t-butyl)-p-cresol and polyoxyethylated alkyl phenol which is mixed with water to form a stable suspension.  The composition is active against a wide range of fungi and may be used in human and veterinary medicines to combat mycosis and also in agriculture as a general fungicide.

Title: Improvements in or relating to aerosol or atomizer devices, and the like
IPC: F24F6/12
Filed: 1957-07-09
Abstract: 859,114. Spray-producers. HESSION, J. W. July 9, 1957 [July 11, 1956], No. 21643/57. Class 69 (3). A portable atomizer has a housing 20 containing an electric motor 29 which drives a fan 30 whereby air is drawn into the housing through slots 32 and delivered to an atomizing nozzle assembly 33. Liquid is drawn from a tank 25, via a tube 35, into the nozzle assembly by the flow of air therethrough and sprayed. The assembly comprises a hollow annular body 54, Fig. 6, into which the liquid is drawn, closed at its rear end by a flexible diaphragm 61. A nose portion 56 extends into the throat of a Venturi tube 43, and has a liquid passage therethrough, the outlet of which is controlled by a valve 68 on a stem 70 attached to the diaphragm. A spring 75 normally closes the valve, but during spraying the air pressure on the rear of the diaphragm opens the valve and liquid is drawn into the Venturi tube where it is acted upon by a primary whirling air stream fed into the tube between circumferentiallv spaced vanes 52 within a stator member 50. The atomized particles flow along the diverging section of the tube towards the sharp edged opening 39 in an orifice plate 36 attached to the housing wall, and are acted upon by a secondary whirling air stream flowing between similar vanes 42 in a stator member 40. The two air streams whirl in opposite directions and the movement of the particles from the orifice is axial. Axial movement of the valve is limited by the abutment of a head 80 on a stem 76 with a screwed knob 77, and by rotating the knob this axial movement is adjusted. Toggle clamps interconnect the tank and housing; legs 83 on the housing base enable it to be supported independently and fed with liquid from a different source. In Fig. 12 a nozzle assembly support 85 is rotatably mounted in an opening in the housing, and the nozzle assembly has a modified mechanism for adjusting valve movement. A U-shaped member 89 is attached to the diaphragm 61 and a pin 90, which is eccentrically mounted between the shafts 91, 92, Fig. 13, passes through the member 89. The shafts are journalled in the nozzle support and by their rotation by a handle 95 the pin position is changed thereby controlling the movement of member 89 and its associated valve. In a further modification, the valve and its control are omitted, and the diaphragm is replaced by a solid wall, and the liquid flow is controlled by a valve in the feed line to the nozzle assembly.

Abstract: 291,262. Nardone, U. Aug. 17, 1927. Propelling by means other than adhesion driving-wheels and racks.-In tractors of the type driven by vertical blades 18 mounted on a chain, the working part of the latter has two inclined sections A, B, without an intervening horizontal section, so that the distances between the blades remain constant. The chain is carried by a frame 2 mounted on one side of a main wheeled chassis 1 carrying arcuate arms 12. The arms 12 rest on supports 11 loose on the axles 10 and may be retained in various positions to regulate the depth of working of the blades by teeth 29 operated by ropes 15. The blades are mounted on the pivots 19 of the chains, Fig. 4. They are held in rigid working position by engagement of an integral pin 21, Fig. 5, with a recess 22 in the links 17, a ball 21<a>, and a spring-pressed bolt 23. Change of inclination of the links relative to the blades after the point C has been passed is allowed by the withdrawal of the bolt 23 by means of a shaft 25, Fig. 4. This is formed with a helical rib 25<1> and carries a toothed wheel 27, which engages a rack at the point C and is thereby rotated. ' Rotation of the rib moves the bolt 23 axially. At the point D teeth 28 on the ends of the blades engage a second rack and cause the inclination of the blades to change as shown. In the new position the bolts 23 resume their former places and relock the blades. The power required for raising the frame 2 is obtained by driving the chassis 1 from left to right, Fig. 1.

[Class 40 (iii).] Received signals are recorded in one or more tracks with variations of width which are an amplification of the movement of the recording chisel M. The depth variations in the tracks are less than the width variations. The recording-chisel moves at right angles to the surface 3 of the record carrier, and the cutting-edges of the chisel are at an angle alpha of 15‹ with the carrier surface. Two cutting-edges in a V are used with an angle of over 150‹ between the two edges. The carrier comprises a layer 2 of gelatine, wax, or metal at least 0.012 mm. thick, covered by an opaque, coloured layer 3 of colouring matter, a developed photochemical emulsion, ink, or colloidal graphite, and backed by a reflecting substratum 1 of paper. Parts of the layer 3 are removed by the chisel together with parts of the adjoining layer 2. The record may be made in metal, such as copper. The amplitude of the movements of the chisel is the same for all signal currents of the same intensity, whatever the frequency. A high frequency of 6,000 cycles is superposed on the received signals. The chisel and associated mechanical system has a natural frequency of 3,000 to 5,000 cycles. A plurality of registrations are made, each corresponding to scanning the same picture with cells sensitive to a different colour. According to modifications : a plurality of tracks is cut, Fig. 4 (not shown) ; the track is cut in ridges in the carrier by a chisel with a horizontal edge, Fig. 5 (not shown).

Abstract: 1340617 Electroluminescence WESTERN ELECTRIC CO Inc 19 April 1971 [16 Feb 1970] 21830/71 Heading C4S [Also in Division H1] A semi-conductor device comprises a semiconductive, electroluminescent, charge carrier storage medium, a means for storing the carriers at a first site in the medium, and a means for transferring the carriers to a second site, a radiative output being obtainable on the recombination of the carriers with the bulk carriers of the medium. Electrode and insulator materials and thicknesses are given. The principle of operation is shown in the shift register of Fig. 2 wherein a series of electrodes 22a, 23a &c. overlie the medium 20 on an insulating layer 21. Carriers at the input 25 migrate to the depletion region 27a under electrode 22a, formed by suitable biasing, and is thereafter sequentially transferred to depletion regions sequentially formed under the next electrode by suitably timed voltage pulses on 22<SP>1</SP>, 23<SP>1</SP> and 24<SP>1</SP>. The carriers may alternatively be generated not only at the input, but along the entire device, by light or other ionizing radiation incident upon the medium, movement of the charges towards the output (by means of suitable voltage pulses to the electrodes), resulting in a video signal corresponding to the image on the medium. Alternatively a video signal may produce an image if the video signal is fed into the device, and when all the sites have been charged, or not, by the signal, a bias on the electrodes may cause the carriers to recombine forming an image in the electroluminescent medium. Fig. 10 is such a device, in which in a medium of N type GaAs P type regions 117a, 118a &c. are formed. The electrodes 115a, 116a &c. form the gate electrodes, effectively, of a series of IGFETS, the drain of one FET forming the source of the next. By applying alternating clock pulses to the electrodes, charge carriers can be caused to travel from site to site sequentially, the channels being opened and closed sequentially. When the final site is reached, all the carriers may be forced to recombine simultaneously with the bulk carriers of the medium producing an image in the medium. This image may be applied to a photo-cathode of a CRT to form an image on the screen. Figs. 5A-5C (not shown) illustrate various output devices. Specifications 1,340618 and 1,340,619 are referred to.
