Transparent diazotype material comprises a transparent support provided with a hydrophilic film layer of a hydrolysed cellulose ester or hydrolysed polyvinyl ester sensitised with a diazo compound where X is an anion, Y is Cl or Br and Z is dibenzylamino or N-ethyl or methyl-N-cyclohexyl- or benzyl-amino. Specified transparent supports are transparent paper or linen and synthetic resin film. Specified optional ingredients of the sensitised layer are acids, stabilizers, e.g. sodium salt of naphthalene 1, 3, 6 tri-sulphonic acid, and reducing agents e.g. thiourea. In Examples I and II surface hydrolysed cellulose acetate on transparent paper is sensitised with a solution of (I) 17. 7g 4-N, N- dibenzylamino-3-chloro-benzene diazonium chloride zinc chloride double salt and 5 g citric acid in a litre of 34% aqueous ethanol (I) and (II) 35 g. 4- (N-methyl-N-cyclohexylamino)-3-chloro-benzene diazonium chloride, 5g. tartaric acid and 30g. sodium naphthalene 1, 3, 6 trisulphonate in a litre of 24% aqueous ethanol. In Example III transparent paper is coated with a hydrophobic layer of cellulose nitrate and overcoated with a hydrophilic layer of 63% hydrolysed cellulose triacetate which is sensitised with a solution of 33g. 4-(N-methyl- N-benzylamino)-3-chlorobenzene diazonium chloride zinc chloride double salt, 6g. citric acid and 10g. sodium benzene-1, 3-disulphonate in a litre of 24% aqueous ethanol. The materials give translucent copies of which the image has a high absorp tion for ultraviolet radiation and which are suitable for intermediate originals for the production of further diazotype copies. They are particularly suitable for processing as described in Specification 957, 836 but may also be used under other processing conditions. Specifications 698, 040, 712, 606 and 726, 755 also are referred to.

It forms salts with inorganic and organic acids, e.g. hydrochloric, acetic, palmitic, pamoic, muric, glutaric and many others.  Lincomycin B is present in the fermentation broth obtained by the cultivation of Streptomyces lincolnensis var lincolnensis according to Specification 976,765.  It is recovered from the clarified broth by treatment with carbon at pH 8.0, elution with aqueous acetone and extraction of the concentrated eluate at pH 10.6.  The extract is concentrated, diluted with water adjusted to pH 1.0 and lincomycin hydrochloride precipitated by the addition of acetone. The mother liquors are concentrated adjusted to pH 9.5 and extracted with methylene chloride and a mixture of lincomycin base and lincomycin B base recovered therefrom. Lincomycin B is separated by counter current distribution of the above mixture in 1 : 1-butanol-water.  Further purification may be by chromatography on, e.g. Florisil and the formation of salts particularly the hydrochloride.  Lincomycin B or an acid addition salt thereof is an antibacterial for pharmaceutical and veterinary use; is a general disinfectant, a preservative for foods and an animal feed supplement. It may be used with other antibacterials, e.g. antibiotics.ALSO:The antibiotic lincomycin B or a salt thereof, either alone or in admixture with other antibiotics, may be used as a feed supplement to promote the growth of mammals and birds. Lincomycin B or a salt thereof may be used to prevent or delay the souring of dairy products such as milk and cheese.ALSO:Lincomycin B or a salt thereof is a disinfectant and may be added to wash solutions for domestic and industrial purposes.

Title: Improvements in or relating to balling guns
IPC: A61D7/00
Filed: 1948-03-11
Abstract: 651,524. Balling guns. MATHER, R., (trading as MINERVA LABORATORIES). March 11, 1948, No. 7491. [Class 81(ii)] In a balling gun for administering medicinal tablets to animals wherein a plunger slides within a barrel the plunger is given, by means of an operating handle, a stepby-step movement in order to eject, one by one, a plurality of tablets previously inserted in the barrel. As shown, the gun handle 16 and cylindrical plunger housing 17 is formed by right- and-left hand units 12, 13, having flat meeting faces which lie in a diametrical plane of the barrel 10 the units being clamped together by nuts and bolts 26, 24, the clamping also securing the barrel 10 which at its inner end abuts the flange 18 formed within the cylinder 17. The plunger 14, slidably mounted in the bearing bush 23, formed by the units at the end of the housing 17, and with its head sliding in the barrel 10 has a stem 28 of channel shape in cross-section notched at regular intervals as at 31. These notches are successively engaged by a spring controlled pawl 41 carried by one arm of the operating handle 15, which, in the shape of a bell-crank lever, is pivoted at 33. The other arm 36 extends into the handle 16 being connected to tension spring 37. The pawl 41 slides in a slot 32 formed by spacing apart the units 12, 13 between the flange 18 and end 21 of the housing 17 and in the position shown is held free of the plunger by co-operating surfaces 43, 44, on the pawl and housing respectively. To load the gun, tablets 47 are fed into the barrel from the muzzle end until the latter is full and by repeatedly moving the operating handle 15 smartly towards the handle 16 the tablets are ejected one by one. A rubber sleeve 45 is stretched over the muzzle end and by lightly gripping any tablet which lies within the reduced portion prevents it falling out if the barrel is inclined downwardly.

Title: Improvements in or relating to apparatus and method for affixing electric components
Inventor: BIRKBECK GUY
IPC: H05K13/00
Filed: 1957-03-07
Abstract: 824,020. Attaching electrical components to circuit boards. MULLARD Ltd. Feb. 5, 1958 [March 7, 1957], No. 7589/57. Class 83 (2). [Also in Group XXXVI] Electrical components 3 with wire leads are affixed to the periphery of a substantially circular platform 1 by rotatably supporting the platform relatively to a component supply station from which a component is moved by a feed member into a desired position on the periphery of the platform, the latter being thereafter rotated to a position for reception of the next component. A circuit unit, preferably for a computer, consists of a number of components 3 located between a pair of platform discs 1, which may have printed circuitry, with their wire ends located in notches 4 in the periphery of the discs and soldered therein. Contact pins 2 connect the unit to an external circuit. For assembling the components the discs are mounted between rollers 11, 12, 13, Fig. 2, with a flat portion 16 of an indicator shaft engaging in a slot 5 of one disc. Components are fed manually or automatically from one or more magazines, or from a turret, into guide slots 17. Upon depression of a spring-loaded handle 18, pivoted at 20, operating links 22 are moved downwardly about their pivots 23 and by means of links 25, cause a feed-arm 26 to pivot in the direction of arrow 28 about axis 27. Jaws 32, 33 of the feed-arm thus engage and shear-off the ends of the component wires against shearing edges 31 and then press the component into adjacent notches 4 of the discs. Upon release of the handle a pawl 46 on link 25 acts through a ratchet 45 and gears 47, 48 to rotate the discs through one notch spacing. After a number of components have been attached a cam 35, actuated by a pawl 39 and ratchet 40, raises a pair of solder baths 34 sufficiently for them to be engaged by a lifting hook 43 on the next operating stroke. This hook further lifts the baths for immersion of a portion of the periphery of the discs into the hot solder for soldering the components. The apparatus may alternatively be adapted for completely automatic operation.

Continued movement of the tools 24, 25, pivots the anvil downwardly against a spring 64 and the bent blank is driven into the receptacle 52 with the tools abutting the face of the die 44. A driving member 34 is driven between the tools into abutment with the bent blank to crimp it to a wire or wires previously located in the receptacle 52. The connector is shaped so as to be crimped to two bared wire ends and to be crimped to the insulation of one or both of the wires. Alternatively the connector may be formed as a terminal to be crimped to the end of a wire.
