IPC: B65G17/00
Filed: 1964-07-02
Abstract: 1,067,125. Endless conveyers. INTERNATIONAL HARVESTER CO. July 2, 1964, No. 27335/64. Heading B8A.  Hay bales X after transport up a shoot 15 by the action of an endless chain conveyer 18 are engaged by faster moving endless conveyer chains 61, 61, and discharged on to a plate 70 which may be manually controlled to (1) lie at the inclination shown, (2) similarly inclined in the opposite direction, or (3) level. The chains 61, 61 and platform 70 are mounted on a carriage 23 (Fig. 2), which has wheels 42 in engagement with rails formed by frame members 13 of the conveyer 18. A pair of driving sprockets 31, 32 of the conveyer chains 61, 61 are driven by the engagement of the chain of the conveyer 18 as it passes over a sprocket 33 and under a pulley 34. The sprockets 31, 32 are smaller than the sprocket 33 to provide the faster speed of the chains 61, 61. The platform 70 is pivotally mounted about an axis A,A and is secured to a member 72. The latter is pivotally connected to links 73, 74 each of which at its lower end is slidably mounted between spaced members 39, 40. An outwardlyacting spring device 81 acts between respective intermediate points on the arms 73, 74. By pulling on a cable 90 secured at 85 to the lower end of the arm 73, the platform 70 may thus be caused to tilt into the position shown in Fig. 1. By pulling on a cable 89 the platform 70 may then be caused to jump back to a horizontal position, and then to an inclined position opposite to the inclination shown. The carriage is held in position relative to the frame 13 of the conveyer 18 by maintaining tension on the cables 89, 90, since when this tension is released, the carriage will tend to move under the action of the chain of the conveyer 18.

Abstract: 405,397. Changing gauge of wheels. COCHRANE, W., 62A, Dennington Park Road, West Hampstead, London. Oct. 3, 1932, No. 27367. [Class 103 (vi).] In railway vehicles of the type in which the lateral spacing of the wheels is adjustable to permit travel on differing gauge tracks the wheels are rotatably mounted on fixed axles or on non-rotating sleeves surrounding the axles. As shown in Fig. 2 the wheels a are slidable on an axle b by means of links c<1> connected to a lever c pivoted at c<2>. One arm of the lever c is provided with holes f adapted to be engaged by a spring plunger connected to a lever j pivoted to the vehicle and operated when a roller I at the end of the lever engages a ramp in the centre of the track. The rails of differing gauge are connected by tapering gauge provided with guide rails for the wheel flanges and the central ramp rail extends the length of the tapered gauge so that the spring plunger is withdrawn from one of the holes f at the entrance to the tapered section and inserted in another hole to lock the wheels when they leave the tapered section. The brake blocks are guided by the wheels along a splined shaft. A dynamo may be driven by a pulley slidable on a splined shaft, the pulley being driven from the boss of the vehicle wheel and slidable by an arm fixed thereto. In Fig. 11 the fixed axle b is provided with lugs n<3> forming guides for bolts n<1> connected by upper and lower straps n, n<4> the latter being fixed to a leg n<7> carrying the ramp wheel n<5>. Bolts are fixed to the strap n and engage in registering holes in flanges on telescopic axles carrying the rail wheels so that when the wheel n<5> rides on the ramp E the bolts are disengaged to allow the tubular axle to telescope and on leaving the ramp engage in other holes to lock the axle in its new position. In hand operated means for adjusting the gauge the wheels are mounted on sleeves which abut at the narrowest gauge but may be separated. One sleeve is provided with an outer sleeve having lugs holes in which can be made to register with holes in a flange carried by the sleeve of the other wheel and the two sleeves locked together by bolts passing through the registering holes.

Title: Heavy metal complexes of cephalosporin c and process for the isolation of cephalosporin c in the form of such complexes
IPC: A47F3/04
Filed: 1969-06-03
Abstract: 1,270,448. Metal complexes of cephalosporin C. CIBA-GEIGY A.G. 3 June, 1969 [14 June, 1968], No. 27942/69. Heading C2A. Novel complexes of cephalosporin C with a divalent heavy metal containing 1 mol. of cephalosporin C per 1 atom of the metal are prepared by adding a water-soluble salt of the metal to an aqueous solution of the cephalosporin C or a salt thereof to precipitate the said complex. The metal may be Hg, Cu, Cd, Co, Ni, Fe, Pb, Zn or Mn and it is added preferably in aqueous solution, in the form of a salt such as the halide sulphate or preferably the acetate. The cephalosporin C may be present as a salt of e.g. an alkali or alkaline earth metal, ammonium or an organic base such as triethylamine. The pH of the mixed solutions is preferably 3 to 7 e.g. 5 to 6, and the complex precipitates if necessary after seeding, cooling or addition of a water-miscible non-solvent (e.g. C 1 -C 5  alkanols or acetone) in a micro-crystalline easily filterable form. The complex may be purified by dissolving it in dilute acid and reprocipitating with a base. The formation of the complex is useful for purifying or isolating cephalosporin C from its impure and/or dilute solutions. The cephalosporin C solution may be a partially purified preparation from a fermentation medium, obtained by a conventional procedure such as absorption on charcoal or ion-exchange resin, or solvent-solvent partition, or by removing byproducts by biological or chemical destruction or absorption on ion-exchanger. The complex may be converted to the free antibiotic by decomposition with alkali or cation exchange resin or by precipitating the metal as the sulphide or an insoluble organic complex, e.g. with 8-hydroxyquinoline or 8- hydroxyquinaldehyde. Alternatively the complex may be used directly to prepare 7-aminocephalosporanic acid.
