Abstract: 270,812. Arnold, C., (Lyons Manufacturing Co.). Feb. 15, 1926. Contents, delivering; fittings, internal; covers. -In a cigarette case in which the cigarettes are delivered one by one through an opening in the case by ejector mechanism comprising levers operated from the exterior of the case, the plate upon which the ejector mechanism is mounted is made independently of the cover of the case, and is adapted to be firmly and detachably secured in the body thereof. As shown the plate 12 has flanges 58 engaging grooves formed by outward projecting ribs 54 on the side walls of the body 10 of the case which is closed by a cover 11 having ribs 40 slidably engaging the ribs 54. The plate has bosses 13 which rest on the bottom of the body 10 and the plate may be held in position by a finger 59 which is sprung under a lug on one of the end walls of the body. The ejector levers 15, 16 have ribs 17 which ride against the adjacent surface of the body and prevent movement of the levers in a direction parallel to the axes of the pin 25 connecting them; the lever 15 is pivoted to the plate 12 by a pin 24 and is formed at its outer end with a push piece 22 which engages the cigarettes and ejects them through the opening in the case when a finger plate 20 on the lever 16 is actuated, a spring 27 returning the levers to their normal position. In a modification the lever 15 is pivoted to the plate 12 and has a rounded end engaging the lever 16 which has a slot engaging a headed pin fixed to the plate. The cigarettes 30 are held in alignment in the case by a flexible strap 31 the ends of which project around and under the, plate 12 between pairs of bosses 13 while a spring 29, acting upon a follower 28 having a slot through which the strap passes, moves the cigarettes towards a pocket 61 in the plate 12 opposite the discharge opening of the case. The sliding movement of the cover 11 is limited by a stop 39 on an angular plate 36 having feet 34 disposed between the bottom of the body and the plate 12 and prevented from moving laterally by the bosses 13 or, alternatively, one of the walls of the plate 12 may be formed with a stop lug which projects into the path of the cover.

Title: The manufacture of aliphatic and cycloaliphatic aldehydes and ketones
IPC: C07C45/00
Filed: 1951-02-27
Abstract: Aliphatic or cyclo aliphatic aldehydes or ketones containing at least 3 carbon atoms are prepared by dehydrogenating the corresponding primary or secondary alcohols in the gaseous state at a temperature between about 350 DEG  C. and about 400 DEG  C. in the presence of an alloy consisting of 65 to 75 per cent of copper, 25 to 35 per cent of zinc and a total of 0.1-1 per cent of iron and/or aluminium and/or bismuth.  The catalyst is preferably used in a reaction tube made of or lined with brass.  A continuous method operated at atmospheric pressure comprises feeding alcohol to an evaporator and passing the resulting vapours to a contact tube containing the catalyst; the reaction product comprising carbonyl compound is led into a film evaporator associated with a distillation column via which the aldehyde or ketone passes to a condensing system and the residue of by-products is recycled from the film evaporator to the feed evaporator.  The hydrogen also produced is withdrawn to desired use. Examples describe the production of butyraldehyde from n-butanol, iso-valeric aldehyde from iso-amyl alcohol, propionaldehyde from propanol, n-hexanal from hexanol, n - heptanal from heptanol, acetone from isopropanol, isobutyraldehyde from isobutanol, cyclohexanone from cyclohexanol, and n-octanal from octanol.  Other alcohols mentioned include n-decanol, n-dodecanol and alkyl cyclohexanols. Specifications 392,652, [Group III], and 610,397 are referred to.ALSO:Alloys for use in catalytic dehydrogenation of alcohols to aldehydes and ketones (see Group IV (b)) consist of 65 to 75 per cent of copper, 25 to 35 per cent of zinc and a total of 0.1 to 1 per cent of iron and/or aluminium and/or bismuth.

IPC: B61H15/00
Filed: 1920-02-17
Abstract: 140,381. Redford, J. E. March 14, 1919, [Convention date]. Compensating for wear.-In an automatic device for taking up slack due to wear of brake blocks, of the type in which relative movement between two elements of the brake rigging is permitted in one direction only on a screw-threaded rod, rotation of the nut is effected by a longitudinal thrust on the rod. The brake levers 1, 2 are connected bv a rod 5, screwed preferably with both right and left hand threads 6, 7 and sliding in a sleeve 4. Inward movement of the rod 5 on applying the brakes is prevented by dogs 10, in the form of spring-controlled rollers, locking the nuts 8, 9 which engage with the threads 6, 7. An additional rod 11, having a frictional fit in a sleeve 12 from which, on application of the brakes, it is drawn out to an extent dependent on the wear of the brake blocks, provides a fulcrum for the wear-compensating outward movement of the rod 5 from the sleeve 4 on release of the brakes. By employing two reversely-operating nuts 8, 9, any tendency of the rod 5 to rotate is prevented.
