Patent GB-787607-A (GB)
Title: Toxin-inactivating substance and preparation
IPC: A61K36/06
Filed: 1955-11-18
Abstract: An antibiotic with an antibacterial spectrum closely related to that of penicillin is produced by the surface culture of Penicillium cyaneofulvum ATCC 11923 on a beef infusion broth containing 1 per cent glucose at 20-25 DEG  C. for 7 days.ALSO:The invention relates to noxiversin which is a protein substance derived from the albumen fraction of a culture of Penicillium cyaneofulrum ATCC 11923 free of mycelium and globulin, effective in detoxifying toxins, effective as a toxoiding agent, non-dialysable, non-antibiotic, non-antigenic, non-toxic, its detoxifying and toxoiding activity not being interfered with by Clarase (penicillin inactivating substance), thermolabile, free of copper sulphate precipitated material, free of dialysable substances, its toxin inactivating activity being attributable to its capability to act directly upon the toxia molecule in contrast to a blocking action.  P. cyanco fulrum is surface cultured on glucose beef infusion broth for 7 days at 20 DEG to 25 DEG  C.  Less suitable is a medium containing malt extract, neopeptone and glucose.  The mycelium is filtered off, the pH of the culture filtrate adjusted to pH 7.0, ammonium sulphate added to 48 per cent concentration and the precipitated globulin removed by centrifugation.  The clear liquid is saturated with ammonium sulphate and the active albumen fraction precipitates and is removed.  This is suspended in saline and dialysed against saline for 48 hours at 5 DEG C. and negative pressure of - 6 mm. Hg. The dialysed albumen fraction may then be lyophilized and stored in ampoules at 4-10 DEG  C. Alternatively, a ten-fold purification is obtained by adding 1 per cent copper sulphate to an aqueous solution of the above albumen fraction and removing the inactive precipitate which is toxic to animals.  The supernatant fluid is dialysed against saline to remove excess copper sulphate. Noxiversin is thermolabile, being completely inactivated in solution after 30 minutes at 70 DEG  C.  It is inactivated by fresh normal serum.  It is used in the preparation of toxoids and antitoxic sera for medicinal and veterinary use.

Title: Improvements relating to electric alarm systems
Inventor: ADAMS FRANCIS JOHN
IPC: H04M11/04
Filed: 1964-08-14
Abstract: 1,065,974. Alarm systems. PYRENE CO. Ltd. Nov. 15, 1965 [Aug. 14, 1964], No. 33250/64. Heading G4H. A local fire station connected to risk  premises has a magnetic tape deck, the magnetic tape having a first track on which a primary alarm message; e.g. the word " fire " repeated several times, is recorded together with a secondary message, e.g. the address of the risk premises. In the event of as fire, the first track is read by head 16 and the primary and secondary messages are transmitted via amplifier 24 to a central station. If a test or fault condition exists, the primary alarm message is replaced by a message from the test or fault track of the tape, but the secondary message is still transmitted. The normal, fire and test conditions are detected by respective relays A, B, C, none of these relays being energized if a fault condition exists. A fourth track on the tape carries a tone signal over a portion corresponding to the primary alarm, test and fault message portions of the other tracks. When a test or fault condition exists, the tone signal picked up by head 19 energizes relay E which cuts out the primary alarm message, contacts of relays B, C substituting the test or fault message. A fire, test or fault condition causes a resistor to be connected intermittently across lines leading to the central station which acknowledges the call by reversing the polarity of the lines, this in turn causing the tape deck to start running. When the transmitted message is understood at the central station, the polarity of the lines is again reversed, and the tape deck stops at the end of message point.

Abstract: 1331168 Spot-type disc brakes KELSEYHAYES CO 15 July 1971 [19 Aug 1970] 33278/71 Heading F2E A rotatable disc is braked by a pad having a pin extending parallel to the disc axis, journalled in and axially slidable relative to a supporting member so that the pad pivots and moves in a direction parallel to the disc axis and parallel to the direction of disc rotation, the pad having means transmitting the pivotal pad movement into movement parallel to the disc axis. A cable operated lever 26 is fixed to the pad 25 to pivot the pad about the pin 27. Pivotal movement of the pad 25 causes a tilting pin 37 to tilt from its original axial position. Tilting of the pin 37 increases the distance from the base of the pin in a tapered seating to the head which engages the pad 25, thus moving the pad against the disc 12. Another pad 29 engages the offered face of the disc 12 by means of a caliper 17 constituting the supporting member floating by means of a pin 31 in elongated slots in a fixed member 32. Wear adjustment is made by a nut 57 threaded in the caliper 17 to adjust the position of the base of the pin 37. The pads are released by springs between the lever 26 and the caliper 17 or around the cable.

Title: Extraction of metal values from complex ores
Inventor: REDMAN MICHAEL J
IPC: C22B5/00
Filed: 1971-07-16
Abstract: 1362683 Copper and nickel recovery KENNECOTT COPPER CORP 16 July 1971 [16 July 1970] 33601/71 Heading C1A Copper and nickel values are obtained from iron containing deep sea manganese nodules or an equivalent complex ore by reducing the ore with a gaseous reducing agent at 249C. to 899 C., leaching the reduced ore (substantially free of metallic iron) with an aqueous solution of ammonia and an ammonium salt and separating off the leach solution containing the copper and nickel values (Co and Mo values may also be contained). The reducing gas may be synthesis gas, a CO/CO2 mixture, a CO/H2 mixture, water gas, and combustion gas from the controlled burning of fuel oil and natural gas. A weaker reducing gas may be used at the higher temperatures, e.g. by adding a diluent such as CO2 or water vapour. The reduction may be carried out in a fluidized bed, a static bed of deep sea nodules where the reducing gas percolates upward or downward, or on a travelling gate wherein the gas passes over the nodules. Prior to leaching the reduced nodules may be cooled in an inert atmosphere and subsequent to leaching if ammonium carbonate is used the metal values may be precipitated as basic carbonates by stripping off ammonia and CO2. The examples also describe the use of aeration or an inert atmosphere during leaching, and of grinding the ore prior to reduction. Other ammonium salts include ammonium chloride and ammonium sulphate.

Abstract: 1,146,862. Coining. L. SCHULER G.m.b.H. 28 July, 1966 [30 July, 1965], No. 33953/66. Heading B3Q. A horizontal coin-press comprises displaceable punches 42, 38, Fig. 5, a die-ring 35, means 61, 63, Fig. 4, for holding blanks 58 in alignment with the die-ring, means for feeding the blanks in a supply plane 73 into alignment with the die-ring, and means for ejecting finished coins in an ejection plane (66, Fig. 6, not shown) spaced from, but parallel to, the supply plane, both planes being perpendicular to the punchaxes. The minimum distance between the planes 66, 73 corresponds to the thickness of the thickest blank to be used. A drive shaft 1 for the press is driven, through a belt, by a motor and carries an eccentric 5 and a sprocket-wheel 13. A connecting rod 6 on the eccentric 5, through a toggle linkage 7, 8 reciprocates the front punch 42, the rear punch 38 being moved, against a return spring (32, Fig. 3, not shown), by a rod 31 operated by a lever 22 which is rocked by a cam 18 on a shaft driven by a chain 14 from the sprocket-wheel 13. Another cam (17, Fig. 1, not shown) on the shaft 16, through a lever 21, operates a spring-returned rod 24 the end 25 of which bears against a pivoted carrier 29, Fig. 4, for the moving jaw 63 of the workholder so as to raise the jaw against the influence of a return spring 28. Also on the shaft 16 is a further cam 47 the follower 48 of which, through a shaft 50 and a lever 51, operates a single slide 54 for feeding blanks and also ejecting finished coins. A recess 57, 60 in the slide receives a blank 58 from a shoot 62, Fig. 4, and delivers it to the work-holder 59, 63 which holds the blank in front of the die-ring When the front punch 42 engages the blank to carry it into the die-ring for the coining operation, the jaw 63 is raised by the rod 25. After coining. the front punch is withdrawn, followed by the rear punch 38 moving in the same direction (Fig. 6) to remove the workpiece from the die. The delivery slide is then advanced so that its leading end 67 strips the coin off the rear punch or off the withdrawing front punch 42 and ejects in the ejection plane (66, Fig. 6). The rear punch then withdraws until its front face is co-planar with the front face of the die-ring 35, to facilitate location of the next blank, before completing its withdrawal. Alternatively, the withdrawal strokes may be uninterrupted. In a modification, Fig. 7 (not shown), the coins are ejected by a lip (72) on the work-holder jaw (63). In this case, the camshaft 16 may be arranged to effect downward, ejection movements of the jaw.

Abstract: 742,167. Spray-producers. INSTITUUT VOOR TUINBOUWTECHNIEK. Dec. 7, 1953 [Dec. 8, 1952; July 13, 1953], No. 33988/53. Class 69 (3). A method of atomizing liquids comprises the creation of a local zone of high air velocity in an air stream, the zone being followed by a local zone with violent vortexes and introducing the liquid as a thin film in the high velocity zone in a direction making an obtuse angle with the main direction of the air stream. In Fig. 1 a hollow body 4 in the mouthpiece 2 of an air duct 1 is supplied with liquid at 7, and the liquid flows from a slitshaped orifice 5 to the edge 6 where it is atomized by air flowing around said edge. In Fig. 2 the liquid is fed through ducts 14 to a chamber 11 between conical parts 8, 9 and flows from an annular outlet 12 to the edge 13 where it is atomized. The part 9 may be hollow to allow air to pass through it axially, and the parts 8, 9 may be urged together by a spring to close the liquid outlet, which outlet is opened by the liquid pressure in a chamber formed between the parts. In Fig. 6 the liquid flows from a duct 49 and through openings 53 to an annular outlet 52 between parts 47 and 50, and flows to the edge 54 where it is atomized by air which is given a rotary movement by vanes 56 and which passes about a cylindrical member 55. Alternatively, the parts providing the annular outlet therebetween are arranged so that the outlet debouches at the atomizing edge.
