Lipoxa mycin is amphoteric and forms acid addition salts (e.g. toluene sulphonate, bromobenzenesulphonate, acetate oxalate hydrochloride and iodate) and base addition salts. The antibiotic is obtained from the filtered fermentation beer by extraction with water immiscible solvent, e.g. methylen chloride at alkaline pH, precipitation from the extract as an acid addition salt by adding an appropriate acid, e.g. H 2 SO 4 , recrystallization of the salt, e.g. from methanol and finally purified, after conversion to the free base form by counter-current distribution, e.g. between ethylacetate, ethylene glycol monomethyl ether water (2 : 1 : 1), and precipitated as the salt by adding an acid or isolated by evaporating the solvent. Alternatively the lipoxamycin may be adsorbed on an anionic, cationic or other resin or adsorbent and subsequently eluted with alkali, acid or solvent.  Pharmaceutical compositions haying antibacterial and antifungal activity comprise lipoxamycin or lipoxamycin mixture as defined above, or an acid-addition salt thereof together with an appropriate diluent or carrier.

Title: Improved fungicidal preparations containing a basic copper salt
Inventor: GLADSTONE MICHAEL NAIRN
IPC: A01N59/20
Filed: 1955-05-18
Abstract: An improvement in the fungicidal composition described and claimed in the parent Specification comprises alkaline earth metal, i.e. magnesium, calcium, strontium and barium carbonate particles, each coated with a continuous film of a fungicidal basic copper salt and preferably having the particles intimately mixed with the particles of a solid finely divided diluent such as calcium carbonate or phosphate, silica talc and kaolin.  The compositions are made by treating an aqueous solution of a water-soluble cupric salt, e.g. chloride, nitrate, acetate or sulphate with a quantity of finely divided alkaline earth metal carbonate in excess of that required to convert the cupric salt into the corresponding basic salt, so as to form an aqueous suspension of alkaline earth metal carbonate particles each coated with a continuous film of a fungicidal basic copper salt.  The aqueous suspension of coated particles may be employed as such as a spraying liquid, preferably after addition of a sticker and/or a suspending agent and/or a wetting agent but preferably, however, the coated particles are separated from the aqueous suspension and are washed, and are then made up with water into a paste or concentrated suspension, preferably with addition of a sticker and/or a suspending agent and/or a wetting agent.  In another embodiment the alkaline earth metal carbonate particles coated with the basic copper salt are recovered in dry form from the aqueous suspension in which they are first formed, and are used as a dusting powder.  Preferably this dusting powder is diluted with a solid finely-divided diluent, e.g. calcium carbonate, calcium phosphate, silica, talc, kaolin, and preferably in such an amount as to produce a dust bulk large enough to be spread evenly from a dusting machine at a desired copper rate per acre.

Patent GB-912091-A (GB)
Title: Process and apparatus for the desorption of charged absorbents
IPC: C10K1/12
Filed: 1959-04-27
Abstract: <PICT:0912091/III/1> Liquid absorbent, which has been used for selectively absorbing an ingredient of a gaseous mixture, is treated to expel the gas by passing humid air therethrough, the humid air being prepared by first passing air through liquid absorbent which has already been stripped of gas, and then treating the air with warm water so that it attains a humidity of 95-100% saturation and a temperature which is 5 DEG -15 DEG C. above the temperature of the unstripped absorbent.  The process is particularly suitable for the removal of gaseous weak acids (e.g. CO2, H2S or HCN) from their solutions, the absorbent liquid being, for example, an alkaline solution or an organic solvent.  Thus, the removal of H2S from sodium carbonate solution, and the removal of CO2 from potassium taurinate solution, are mentioned.  In the drawing, the liquid absorbent is sprayed down a packed column 19 and is stripped therein by a countercurrent of humid air which is produced in packed tower 1. Tray 7, having covered vents, divides tower 1 into two parts, air entering the lower part through pipes 9 and 10 and moist air leaving the upper part through pipe 23.  Stripped absorbent from column 19 enters the lower part of tower 1 through spray 3 and runs from the base of the tower into receiver 14.  Water from tank 17 is pumped by pump 16, through heater 15, to the distributer 6 in the upper part of tower 1, while water collecting in tray 7 flows back to tank 17. Make-up water, to replace that consumed in moistening the air, is fed into tank 17, the flow of make-up water being controlled by the level in tray 7.  Where the absorbent liquid is a solution, the passage of air through it, in the lower part of tower 1, alters the concentration of the solution.  The concentration may be maintained at the desired value by means of impulse transmitter 12 in receiver 14.  This transmitter, in response to changes in the concentration of the solution in receiver 14, operates the flow regulator 11, so that the proportion of air entering tower 1 through the pipe 9 is varied.

Title: Pencil
IPC: B43K21/02
Filed: 1922-05-22
Abstract: 199,913. Golby, F. W., (Dow, L. F.). May 22, 1922. Pencil-holders.-In pencilholders of the kind comprising inner and outer casings telescopically connected with freedom for longitudinal and rotary movement in respect to each other, the inner casing supporting the lead carrier is used as a receptacle for spare leads, and is circumferentially expanded along a portion of its length to increase its frictional engagement with the outer casing. The lead carrier comprises a metal sleeve 14, Fig. 2, folded around the stem of a pin 12 of less length, the lower end of the sleeve forming spring jaws 15 to hold the end of a lead 16. The upper and lower surface of the head 13 of the pin are preferably rounded and the stem is passed through a central hole in a washer 17 secured by an annular head 19 in the lower end of the inner casing 5. A disc 18 bearing upon the head of the pin is secured in position bv a similar bead 19. The outer end of the casing is expanded to form a socket 8 for an eraser 9 which is retained by a bead 10, and a shoulder 11 is provided at the lower end of the socket to limit the inward movement of the casing. The space between the eraser and the disc 18 in the casing 5 is used as the receptacle for spare leads. A longitudinal slot 20 forming a passage for the leads is provided in the expanded portion 21, Fig. 3, and arranged to be uncovered when the casing is drawn out to its full extent. The lower end 7 of the outer casing 6 is tapered to a hole of sufficient size to allow the lead to be moved freely therein without friction.

Abstract: 569,702. Belt gearing. WALTERS, F. J., and SMITH, W. S. Sept. 6, 1943, No. 14586. [Class 80 (i)] Consists in a right-angle belt drive in the form of a compact unit which may replace the usual gear-box with toothed gearing. Input and output shafts A, B respectively are mounted at 90 degrees to one another in bearings C, E adjacent and at right-angles to one another, and located in a casting F which completely encloses the entire drive. On the inner ends of the shafts A, B are mounted V-groove pulleys G, H, and further V-groove pulleys O, P are mounted on a countershaft J carried by a saddle K which is vertically slidable on guide rods L, M and is adjustable either automatically by a spring or by adjustment of a stud N. The pulleys in each stage of the drive are therefore inclined relatively at 45 degrees. All the pulleys may be of the same diameter or of different diameters, but in the latter case the sum of the diameters of the pulleys in the first and second stages of the drive is constant so that the same length of rope is used and the stretch is uniform.
