Title: Process for purifying and hydrogenating naphthalene
IPC: C07C7/148
Filed: 1934-06-23
Abstract: Crude naphthalene is purified with a view to subsequent hydrogenation by vaporizing, and conveying without cooling, through two purifying chambers in series, of which the first contains iron, copper, nickel, cobalt or chromium, disposed so as to afford an extensive contact surface as in the form of gauze or wire, and the second contains a mixture of porous carbon and calcium iron, copper nickel cobalt or chromium, advantageously obtained by calcining the compounds resulting from the action of acetylene on these metals or carbon and the oxides of the said metals at a temperature of 250--400 DEG  C. The purifying apparatus may be in duplicate, one series being regenerated by a current of air through the first chamber and of steam and hydrogenating gas through the second while the other series functions as a purifier. The purified naphthalene may be hydrogenated by known means, preferably by a hydrogenating catalyst of nickel or an organo-metallic nickel compound in presence of an industrial hydrogenating gas containing not less than 30 per cent of hydrogen. The naphthalene hydrides are condensed and may be used as solvents for waxes, resins, gums or as stabilizers for industrial alcohol in gasoline, increasing the latter's resistance to detonation.

Title: Method of and means for separating membranes of animal intestines
IPC: A22C17/14
Filed: 1949-07-18
Abstract: 664,731. Sausage skins. CASTELOW, A. H. July 18, 1949, No. 18901/49. Class 28 (ii). [Also in Groups VIII and XXV] The inner membrane or skin 8 of beef intestines is separated at least, partly, from the tougher outer skin 7 by crushing and rupturing the intervening: fibrous tissue 9, the crushing &c. being done by a beating roller, after which a solid separator or pressure fluid is passed between the skins to separate, them, partially or completely. The inner skin 8 is then used as sausage skins while the outer skin 7, or the tougher upper part only, may be made into string gut. The crushing may be done by simple pressure between rollers, and pressure water may then be forced between the skins to effect separation. The separation may also be effected either by a single ball or two balls forced between the skins as described later. The rupturing of the intervening fibrous tissue 9 may be effected in the machine in Fig. 2 in which an intestine is manually pushed over a spreading cage like end 20 of a carrier bar 19, 21, after which it is gripped between fluted rubber rollers 12, 13 and so fed along the bar and pulled along also by like end rollers 16, 17. The roller spacing is adjusted by turn screws 36. In its passage over the bar 19 the intestine is beaten and scraped by rubber &c. blades 38A mounted tangentially or radially on a rotated roller 38 which thus breaks up the fibrous tissue 9 between the membranes. The beater roller 38 is adjustable towards and from the mandrel. The bar 19 is shaped with an under channel 25, Fig. 5, to prevent the weaker underpart of the intestine and its adjoining rib 10 of fat from being broken up. Water pipes 48 spray water within the machine, the water being run off over drip trays 50. The bar 19 has a short detachable guiding end 23 with end prongs for plugging in on the bar. The machine may be constructed with a number of carrier bars 19 to receive a number of intestines simultaneously. The rubber beating blades 38A may be replaced by a set of small beating rollers on the periphery of the roller 38. In a simplification the rollers 12, 13 only are used which are adjusted to gear together and crack and break up the fibrous tissue 9 when the intestine is passed between them without being threaded on a carrier bar 19. In another modification the bar 21 is round so that peripheral crushing of the intestine takes place except at the side gaps when the rollers do not quite meet. After breaking up the fibrous tissue 9 pressure water may be forced between the outer and inner membranes to separate them wholly or only partly around the periphery. Alternatively the intestine with one or more balls located between as in Fig. 6 and 7 is pulled over the balls whereby spaced parallel blades 59 cut an upper strip from the outer membrane which is the best quality for making string gut. The inner membrane with remaining attachments is pulled away between the legs 54, Fig. 6, of the device, and later becomes the sausage casing.

Class 103(1) In a fabricated brake shoe, the working surface of the brake lining when not under load is of transversely and outwardly concave form, so that it becomes transversely flat under full load due to deflection of the shoe head. The brake shoe comprises 'a web portion 10 to which an arcuate head plate 11, of transversely and outwardly concave form, is secured by welding at 12. Secured to the head plate 11 is a brake lining 13 of complementary shape and uniform thickness. When light rubbing loading is applied, only the longitudinal marginal edge portions of the working surface 14x of the lining 13 make contact with the brake drum 15. As the loading increases, the surface area of the lining in contact with the drum will increase as the concavity of the brake lining 13 is in full contact with the drum 15. An alternative arrangement is described where the head plate 11 is transversely flat and only the working surface of the lining 13 is of transversely and outwardly concave form.
