Title: Hydrocarbon conversion catalyst and process for producing the same
Inventor: MEISINGER ERWIN ELMER
IPC: B01J27/24
Filed: 1960-11-01
Abstract: A hydrocarbon conversion catalyst, used for the polymerization of olefins particularly to obtain the dimer-(2-methyl-2-pentene) and trimer from propylene-as well as for side-chain alkylation of alkylaromatic hydrocarbons and isomerization of unsaturated hydrocarbons to shift a double bond, e.g. in butene-1 or 2-methyl-1-pentene to a more central position without further olefic polymerization, comprises an alkali metal amide on an anhydrous metal oxide support (e.g. Al2O3 and particularly its g -, c - and #q-modification) of surface area 25-500 m2/g, the metal oxide having been promoted by compositing with an alkali metal or compound thereof.  Other specified olefines which may be polymerized are ethylene, butene-1 and -2, 1 : 3-butadiene, 2-methyl-1 : 3-butadiene, pentadienes and hexadienes. The alkylaromatic hydrocarbons must contain at least one replaceable a -H atom and include, e.g. toluene, the xylenes, ethyl-, propyl, and butyl-benzene and the diethyl- and dipropyl-benzenes.ALSO:A hydrocarbon conversion catalyst comprises an alkali metal anide on an anhydrous metal oxide support (e.g. Al2O3 and particularly its g -, c - and #q-modifications) of surface area 25-500 m.2/g., the metal oxide having been promoted by compositing with an alkali metal or compound thereof.  The alkali metal of both the amide and the promoter may be Li, Na, K, Rb or Cs, but preferred ingredients are Li2O and KNH2. In one example, the catalyst apparently also contains ferric oxide.

Abstract: 1,130,777. Elastomeric springs. GESELLSCHAFT FUR TECHNISCHEN FORTSCHRITT m.b.H. 22 Aug., 1966, No. 37478/66. Heading F2S. A spring with a relatively large compression path comprises a ring 1 made of solid, natural, or synthetic rubber and located, without bonding, between load plates 2, 3 the ring 1 having a greater curvature on the outside than on the inside and the rubber material, which remains constant in volume, being displaced outwardly under load so that the ring 1 rolls over the spring plates 2, 3 and the line of action of the load, which is initially nearer to the internal than to the external diameter of the ring, is progressively moved outwards as the loading increases and more parts of the ring come into contact with the bearing plates 2, 3. Bosses on the insides of the plates 2, 3 centre the spring. In an alternative arrangement a plurality of rubber rings are stacked vertically, one above the other, with intermediate plates provided with centring bosses on both sides. In another arrangement several stacks of springs are arranged concentrically one within the other, intermediate plates with bosses on both sides being provided.

Title: Automatic three-ratio speed change bicycle hub
IPC: B62M11/14
Filed: 1968-08-07
Abstract: 1,239,794. Change-speed gear. SHIMANO KOGYO K.K. 7 Aug., 1968 [12 Aug., 1967], No. 37675/68. Heading F2D. A three ratio cycle hub planet gear has its ratio shifted automatically by input and output driven centrifugal governors 33, 44. The gear has planet pinions 17 on a carrier 20 meshing a fixed sun gear 16 and a ring gear 12 on a carrier 15. The planet carrier 20 and ring gear carrier 15 are selectively connected to a block 8 fast with a driving sprocket 11 by ratchet clutches 25, 22 and to a driven hub 2 by ratchet clutches 28, 31. The ratchet clutches 25, 31 are held disengaged by the centrifugal governors 33, 44 when the input and output speeds are below predetermined values. For low ratio, with the ratchet clutches 25, 31 disengaged, the block 8 drives the hub 2 through the ratchet clutch 22, ring gear carrier 15, planet gear 12, 17, planet carrier 20 and ratchet clutch 28. When the speed of driving block 8 exceeds a predetermined value the governor weights 33a, 33b pivot outwardly against the bias of a spring 43 to release the pawl of the ratchet clutch 25, whereupon the gear upshifts to direct-drive with the block 8 driving the hub 2 through the ratchet clutch 25, planet carrier 20 and ratchet clutch 28. The ratchet clutch 22 overrunning. When the speed of the hub 2 exceeds a predetermined value the governor weights 44a, 44b pivot outwardly against the bias of a spring 54 to release the pawl of the ratchet clutch 31, whereupon the gear upshifts to overdrive with the block 8 driving the hub 2 through the ratchet clutch 25, planet carrier 20, planet gears 17, 12, ring gear carrier 15 and rachet clutch 31. The ratchet clutches 22, 28 overrunning. The speeds at which ratio shift occur may be varied by adjusting the strength of the springs 43, 54. When the input and output speeds fall below the predetermined values downshifts are prevented until a torque reversal occurs (i.e. back-pedalling) to bring the pawls of the ratchet clutches 25, 31 into a position in which they are held disengaged by the governor weights. The governors 33, 44 may be adjusted so that the ratchet clutch 31 is engaged before the ratchet clutch 25 in which case the block 8 drives the hub 2 through the ratchet clutch 22, ring gear carrier 15 and ratchet clutch 31 for direct-drive. The other ratios being as specified above.
