Title: Process for producing a hydrogen-rich gas
IPC: C10G11/20
Filed: 1975-03-26
Abstract: 1516362 Reforming hydrocarbons STONE & WEBSTER ENG CORP 26 March 1975 [9 April 1974] 50559/77 Divided out of 1516361 Heading C5E A process for generating a hydrogen-rich gas comprises the steps of (a) passing a hydrocarbon/ steam mixture through catalyst-filled reformer tubes at a pressure of 200-300 p.s.i.a., the tubes being located in a convection heating zone of a furnace having a combustion zone and a burner section, (b) heating the mixture in the tubes to 1000F-1550F by convected heat with gases generated in the furnace combustion zone, (c) preventing radiant heat from the combustion zone from directly heating the reformer tubes by providing a barrier between the combustion zone and the convection zone, and (d) maintaining the pressure of the combustion gases in the convection zone in contact with the reformer tubes between 100 and 180 p.s.i.a. An example is described in which methane is steam-reformed, but the process is also of particular use in the catalytic reforming of higher hydrocarbons such as propane, hexane or naphtha. Specification 1,516,361 relates to a furnace for performing the process.

Abstract: 1,132,073. Coating. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 30 Nov., 1965, No.50788/65. Heading B2K [Also in Division H2] In a method for producing a laminated stator core for a dynamo-electric machine such as a squirrel cage motor, the stack of laminations 4 are clamped together, a layer of epoxy resin is applied only to the walls 16 of slots 12, 14 formed in the laminations and to regions of each end face 8 of the stack and the resin is hardened so that on removing the clamps the core remains secured together solely by the hardened resin. The laminations are clamped in a jig (Fig. 2, not shown), by rings (24, 26) which have spaced apart lugs (25, 27) arranged in a staggered formation so that when the ring (26) is rotated by a bar passed through lug (28) the ring (26) is forced downwardly to clamp the lamination. Masking of the stack ends at 4, may be obtained by rubber tubes positioned within the jig. Also a masking member is placed in the centre bore 116, to prevent a deposite on the bore. The jig is heated and immersed in a fluidised bed of resin and after removal and further heating the resin hardens. Alternatively the resin may be applied to the core by electrostatic spraying.

Abstract: 1,135,028. Endless conveyers. T. FUJITA. 10 Dec., 1956 [10 Dec., 1964], No. 52658/65. Heading B8A. At least two conveyers 2, 10 (Fig. 1), operating at respective different speeds are connected by at least one further conveyer 4, the speed along which progressively changes so that the further conveyer(s) 4 form a smooth transition between the two conveyers for loads which comprise load supporting plates 29 (Figs. 12, 13) each of which is adapted to be driven along by the action of frictional engagement between the plate 29 and moving surfaces of the conveyers. In Fig. 1, a pair of roller conveyers 10 are arranged to run at a speed (30 metres per minute) slow enough for passengers to board a chair 10 carried by (each plate 29) from a platform 26 (Fig. 15). Each conveyer 10 feeds, or is fed by, one of the conveyers 4. An assemblage of conveyers 2, 4, and 10 are arranged to form a closed circuit-Fig. 1 and Fig. 2 (not shown). Each conveyer 4 comprises laterally spaced rubber tyred rollers (7) (Figs. 6-8, not shown), carried by each of a longitudinally spaced series of roller drive shafts (6). The driving connection between the shafts (6) and the rollers (7) is through an over-run ratchet clutch (Fig. 9, not shown). Each shaft (6) is connected to the next downstream shaft (6) by a speed changing chain drive, the final downstream shaft (6) being connected to a drive motor. This results in a progressive increase or decrease in driving speed of the conveyer along its length. Where a conveyer section has a curve of small radius (11, Fig. 1) only the radially-outer roller (7) of each shaft (6) is driven (Fig. 10, not shown). A single endless belt may provide the conveying circuit for two side by side conveyers 2 which are intended to convey in opposite directions. In order to suitably return the belt back and forth it is twisted into a vertical plane in runs (A) (Fig. 4, not shown). Each chair 29 is pivotally mounted at 28 on its respective plate 19. A pair of rollers 31 engage rails 33 the height of which are suitably varied to keep the chair 29 in a correct attitude even on inclines. Rollers 32 mounted on a vertical axis, co-operate with rails 34 to maintain directional stability. A section of the rails 33 may be deflectable (Fig. 16, not shown) so as to enable the rollers 31 to escape therefrom.
