Abstract: 1284949 The antibiotic espinomycin NIKKEN CHEMICAL CO Ltd 6 Aug 1970 [9 Aug 1969] 38010/70 Heading C2A The novel antibiotic espinomycin comprises espinomycins A and B characterized as follows:- and is prepared by cultivating Streptomyces fungicidicus var. espinomyceticus (ATCC 21574) or an espinomycin-producing mutant or variant thereof aerobically in a nutrient medium. Espinomycin is a basic macrolide type antibiotic forming acid-addition salts and having antibacterial activity against gram-positive bacteria. It may be isolated from the whole fermentation beer or its filtrate, by acidification followed by extraction with a water-immiscible solvent, e.g. alkyl esters, chloroform, butyl alcohol or methyl isobutyl ketone. The separated extract is evaporated to low volume and back extracted with aqueous acid; the solution is then neutralized or made slightly alkaline to precipitate the espinomycin. Alternatively the neutralized solution is extracted with benzene, and the extract evaporated to low volume and cooled, when espinomycin B crystallizes out. Espinomycin A is obtained by evaporating the mother liquor from this crystallization to dryness. Espinomycin may also be isolated by absorption on carbon or ion-exchange resin followed by elution with aqueous acid or a solvent. Espinomycin A is further purified by chromatography on alumina and then on silica gel; the pure product is converted to its tartrate salt. Pharmaceutical compositions having antibacterial activity against gram-positive bacteria comprise espinomycin or its components A or B as defined above or a non-toxic acid-addition salt thereof, together with a pharmaceutically acceptable diluent or carrier.

Title: Television system
IPC: H04N7/16
Filed: 1959-11-10
Abstract: 939,930. Coin feed television apparatus. BRITISH TELEMETER HOME VIEWING Ltd. (Paramount Pictures Corporation). Nov. 10, 1959, No. 38127/59. Class 27. [Also in Groups XXXIX and XL (b)] In a coin-freed mechanism for a subscription television system the price to be paid for each programme is initially set-up under the control of pulse signals from a central transmitter which rotate the price wheel 310, Fig. 7, from a blank setting (viewed in a window, Fig. 3, not shown) downwardly, in price from a maximum price indication, until the price to be paid appears in the window. This (clockwise) rotation is effected by a ratchet wheel 307 the co-operating pawl member 305 of which is operated by electromagnets 300, 301, the former, in response to each received control pulse, stepping the ratchet wheel through an angular distance corresponding to one tooth and the latter 301 stepping it through a distance corresponding to five teeth. After the price has been set-up the insertion of coins in the mechanism causes operation (by means not shown) of either, or both, of electromagnets 300, 301, depending on the value of such coins, which rotate the ratchet wheel, in the same direction as that which sets up the price demand, until the end of the price scale has been reached and the word " paid " appears in the viewing window. The coin slot is now closed by a door to prevent the insertion of further coinage. In this position the cam 306 operates switch 209 connected in the " scrambling " circuits of the system and allows the programme to be viewed. At the end of each programme a release electromagnet 302 is operated to allow the ratchet wheel to return to its normal stand-by position such rotation occurring in a counter clockwise direction. The central transmitter also transmits, inter alia, pulses which serve to identify each programme and pulses representative of " voting " identification data. The former are recorded on magnetic tape in the coin-box whenever a programme has been paid for whilst the latter are only recorded if the subscriber operates a push-button to indicate a preference (to whatever is being shown) in response to a transmitted request in the programme. The coin-box also contains a switch which operates by breakage of the magnetic tape to prevent operation of the system and additionally a " tilt " switch is fitted to prevent fraudulent operation e.g. by tilting the coin box to cause a coin of a given value to operate the circuit associated with a coin of a higher value, such switch operating to prevent any operation by the deposited coin. U.S.A. Specification 2,843,655 is referred to.

Patent GB-372830-A (GB)
Title: Improvements in suspensions for road vehicles
IPC: F16F7/04
Filed: 1930-12-19
Abstract: 372,830. Vehicle suspension; shockabsorbers. CARWARDINE, G., 17, Macaulay Buildings, Bath. Dec. 19, 1930, No. 38276. [Classes 108 (ii) and 108 (iii).] Frictional restraint, the amount of which is dependent upon the relative movements between the sprung and unsprung parts of a vehicle, is provided in connection with suspension systems of the 'kind in which a resilient device is employed to assist or oppose movements of the main suspension springs on one side or the other of their normal position. Such resilient devices, when used in conjunction with the more or less simple harmonic forms of suspension, are intended to provide a resultant system of constant periodicity whatever the vehicle load, as referred to in Specifications 263,925, [Class 108 (ii), Road vehicles, Undercarriage details &c. for], and 349,582. In the construction shown in Figs. 1 and 2, the arms 20, 8 are pivoted respectively to the frame and the axle and are connected to one another by the pivot 24. A strong helical compression spring 18 is interposed between the pivot 7 at the end of the arm'20 and a pivot 9 towards one side of the arm 8, the position of the pivot 9 being such that the pivots 7, 9, 3 are in lines as shown when the vehicle is normally loaded The helical spring 18 acts so as to raise or lower the frame according to whether it is above or below the neutral position. Angular movement of the levers 28 is resisted by.friction disc devices 27, 28, 29 clamped by a star-shaped spring 26 and a centre bolt 24 between the two parts of the arm 20. The friction between the discs increases with the angular movements of the arms 20, 8, this result being achieved by a number of balls 32 interposed between the plates 23, 30 and entering recesses as shown in Fig. 3. Relative.rotation of the plates 23, 30 in either direction causes the balls to roll up the sides of the recesses and separate the plates thus increasing the pressure between the friction discs 27, 28, 29. The recesses in the plates 23, 30 may be unsymmetrical so as to obtain greater pressure on the rebound than on the compression of the main springs. The friction between the discs may be controlled by the absolute movement of the apparatus, i.e. independently of the relative movement of the frame and axle. With this object rotation of the plate 30, Figs. 7 and 8, is controlled by the inertia of a heavy mass 36 on the end of an arm extending from the plate. Friction may be introduced between the abutment of the spring 18 and the pivot as shown in Fig. 6, Angular movement of the spring 18 causes a roller 34 mounted on a pivot to engage: either of the friction faces 35.

Abstract: 1360007 Liquid polyurethane compositions DULUX AUSTRALIA Ltd 17 Aug 1971 [17 Aug 1970] 38482/71 Heading C3R Liquid polyurethane compositions essentially free of polymer particles visible under an optical microscope and comprising a self-stabilized dispersion of gelled urethane polymer in an organic liquid are prepared by reacting a polyisocyanate and a polyhydroxy precursor at a total concentration of reactants not exceeding 30% by weight in an inert organic liquid in which the reactants are essentially soluble at the reaction temperature with the limitations that (a) the polyisocyanate comprises on average at least 1À5 isocyanate groups per molecule, (b) the polyhydroxy precursor comprises on average at least 1À5 OH groups per molecule and at least 30% by weight of pendant chains having a structural backbone of at least 10 covalently linked carbon atoms, the said chain being solvatable by the inert organic liquid but inert with respect to the urethane gel-forming reaction, (c) the polyisocyanate and polyhydroxy precursor in combination shall comprise at least 15% by weight of the pendant chains and (d) the mixture of polyisocyanate and polyhydroxy precursor is selected to be a gellable composition which at a concentration of at least 50% by weight in the inert organic liquid reacts to form a visible polymeric gel. The polyisocyanate may be aliphatic or aromatic and may be tolylene diisocyanates, hexamethylene diisocyanate, pphenylene diisocyanate or diphenylmethane-4,4<SP>1</SP>- diisocyanate. Suitably the pendant chains of the polyhydroxy precursor are hydrocarbon chains which may be saturated or unsaturated. Such precursors may be (1) polyhydroxy partial esters of a fatty acid and a polyol, (2) an ester of a fatty acid and an epoxy resin or (3) an alkyd resin containing unreacted OH groups. The inert organic liquid preferably at least in part is a drying oil. Paint compositions may be prepared by dispersing pigments in the liquid compositions. Conventional paint vehicles, e.g. solutions of alkyd resins in a volatile liquid may also be added to the compositions. In typical examples a polyhydroxy precursor is prepared by reacting soya oil fatty acids with a polyhydric alcohol, dipentaerythritol, pentaerythritol, sorbitol, glycerol, tripentaerythritol and trimethylolethane, diluted with xylene and reacted with tolylene diisocyanate.

Title: Improvements in the dry spinning of cellulose ester filaments and the like
Inventor: CAMPBELL NORMAN BERNARD
IPC: D01F2/30
Filed: 1958-12-01
Abstract: Filaments &c. are produced by dry spinning a solution of a cellulose ester into an atmosphere maintained above the boiling point of the solvent and consisting of the superheated solvent vapour alone or mixed with up to an equal volume of air or other inert gas.  The solvent may be acetone but more particularly the esterifying mixture in which the cellulose acetate is produced. In such a mixture the solvent may consist wholly of an aliphatic acid (particularly an aliphatic acid containing 2 to 4 carbon atoms) or may also contain a small proportion of water after the ester has been ripened, or may consist of a mixture of the acid with the acid anhydride used to esterify the cellulose.  The invention is most advantageously applied to the production of filaments &c. from triesters of cellulose in solution in the mixture of acid and anhydride in which they are produced.  The atmosphere into which the ester solution is spun may then consist of the super-heated aliphatic acid and/or aliphatic acid-anhydride.  In an example, a solution of cellulose acetate in an esterifying mixture boiling at 123 DEG C. and consisting of acetic acid and acetic anhydride in which the sulphuric acid catalyst has been neutralized with magnesium acetate is extruded at 100 DEG C. through a conventional spinning jet into a closed spinning cabinet heated electrically to 180 DEG C.  The cabinet is sealed except for a small aperture for the withdrawal of the yarn and a vapour exit line to a condenser.  The spinning is conducted without admission of air using normal take-up equipment and a feed roller speed of 135 metres per minute.  The process of the invention has the advantage over conventional dry spinning into heated air that the solvent can be recovered by simple condensation.  Specification 791,367 is referred to.

Abstract: 1,068,044. Boots &c. RO-SEARCH Inc. Oct. 3, 1963 [Oct. 3, 1962; Nov. 26, 1962], No. 38953/63. Heading A3B. [Also in Division B5] A method of moulding soles on to shoes and lasting the upper at the same time comprises closing a mould cavity by an upper on a last, exerting pressure through elastomeric material in the cavity to move the last heightwise in relation to the upper to tighten the upper on the last and holding it tightened while the elastomeric material is moulded and cured. The upper may be tightened on the last by holding the supper stationary and forcing the last uwards under the pressure of the elastomeric material. The elastomeric material may be a natural or synthetic rubber and pressure may be applied by expanding the material e.g. by heating with or without a blowing agent or by injection moulding the material in the form of a plastisol. In a first embodiment (Fig. 1) the upper 1 is held stationary by a perforated strip 4 attached to the edge of the upper and which is clamped between mould halves 5, 6. A rubber mix 3 containing a blowing agent is expanded to force the last upwards to stretch the upper. The rubber mix flows through the perforated strip 4 to form the side of the sole. The upper may have a sock lining 2. In a second embodiment the upper is connected by a perforated strip or an extension of the upper to a tread sole and again a rubber mix is expanded to force the tread sole against the bottom of the mould and to force the last upwards. In a third embodiment (Fig. 7, not shown) the upper is held stationary by a lip (32) on the mould engaging a folded seam (33) on the upper or a cord (not shown) sewn along the edge of the upper. When assembling the upper a pocket may be sewn to the counter and/or toe of the upper so that the elastomeric material may flow into the pocket during moulding to form a counter and/or toe stiffener which is integral with the sole. When assembling the upper having a tread sole atached the upper may be made by the turnshoe method.
