Abstract: 748,916. Liquid-electrode apparatus. GENERAL ELECTRIC CO., Ltd., and MORRIS, C. H. Nov. 3, 1953 [Nov. 3, 1952], No. 27640/52. Class 39 (1). A vapour electric arc converter having a pool-type cathode 8 and arc ignition means including a plunger 6 arranged to eject cathode material from the pool towards another electrode 15 has magnetic means separate from the arc ignition means positioned to attract magnetic particles and prevent them reaching the plunger. The magnetic means can comprise a ring 12 of permanent magnetic material such as a permanent magnet placed around a part of the converter vessel above the cathode pool and/or a ring 14 of permanent magnetic material placed in the cathode pool around the axis of operation of the plunger 6. The ring 12 is apertured or grooved at 13 and a cylindrical filtering baffle 16 of molybdenum is placed around the ring 14 so as to project above the cathode pool.

Title: Improvements in and relating to a method and apparatus for generating hydrogen from liquid hydrocarbon feedstocks
IPC: B01D53/22
Filed: 1966-06-24
Abstract: 1,156,563. Hydrogen. UNITED AIRCRAFT CORP. 24 June, 1966 [3 Aug., 1965], No. 28253/66. Heading C1A. [Also in Division C5] In the preparation of substantially, pure hydrogen, a hydrocarbon feedstock in tank 2 and water in tank 4 are mixed via valve 14 and the mixture pumped via 16 into optional feed preheater 20. From here it passes on to tube 26 in boiler 24 where the temperature is raised to 205‹ to 510‹ C. The feed stream then passes on to pre-reactor 30 which contains a dehydrogenation catalyst 32 which is heated by a fluid passing through tubing 34 so as to maintain a predetermined increasing thermal gradient from the inlet to the outlet of the catalyst bed so as to avoid catalyst poisoning the outlet temperature of the bed being 370‹ to 650‹ C. and where initial conversion of the feedstock occurs to produce methane, hydrogen and oxides of carbon. The product stream passes on to primary reactor 36 where under the influence of dehydrogenation catalyst 38, further reaction occurs to give hydrogen and CO from the methane originally present, the catalyst being heated to a temperature of 700‹ to 990‹ C. by the burner 40. The product stream then passes back to pre-reactor 30 and becomes the fluid which passes through tubing 34 to produce said predetermined thermal gradient in catalyst 32. Passage through 34 decreases the temperature of the gas stream which is then passed through catalyst 42 in shift converter 44 wherein CO reacts with steam to produce more hydrogen. The converter 44 is coupled to the hydrogen purifier 46 so as to supply heat thereto and the gas stream is passed from the converter into contact with one side of a membrane 48 which is selectively permeable to hydrogen which diffuses through and is collected from the opposite surface. The waste gas from purifier 46 is burnt in burner 40 to supply heat to bed 38, and combustion gases from 40 supply heat to boiler 24 through tube 28. The heat from the substantially pure hydrogen stream is utilized in preheater 20 via tube 22. The system operates under a pressure of 7 to 28 kg./cm.<SP>2</SP> and items 50, 62, and 64 represent valves controlling and permitting exit from this pressurized system. A compact apparatus in which boiler 24, prereactor 30 and reactor 36 are combined in a single vessel is described and claimed (Fig. 5, not shown), and in a preferred arrangement the shift converter 42 is arranged as an annulus around the purifier 46. To start up the reactor, the burner 40 may be fed with fuel and air from an alternative source, e.g. fuel tank 56 and air supply 68. All the various items mentioned may be assembled in a single container (Figs. 2 and 3, not shown).

[Class 132 (iii).] A toy which simulates the feeding of an infant or animal by means of a nursing bottle is provided with an inner resilient or flexible container communicating with a mouth opening which is adapted to receive a liquid receptacle, means being provided to permit the necessary displacement of air when liquid is transferred from the receptacle to the container by suction upon the compression and release of the container. As shown in Fig. 1, a rubber bulb 9, situated within the body of a doll 5 and connected to the mouth 6 by a flexible tube 8, is accessible through an aperture 10 in the wall of the body to enable its compression and release, to force liquid into a bottle 11 and to suck it therefrom, respectively. Holes 15, 16 are formed in the bulb to enable the pressure within the bulb to be balanced with that of the atmosphere. In modifications, the bulb is situated within the head of the doll or may be comprised by the head of the doll. In a further modification, Fig. 5, the nipple 35 of the bottle 40 is surrounded by a flexible sleeve 36, and the bottle is formed with an air vent 39, that, during the sucking operation, admits air to the bottle with a sucking noise. Instead of forming the air vent in the bottle itself, it may be formed as a duct or ducts in the neck of the bottle, in the sleeve 36, or in the nipple 35, the effective area of the duct being variable by adjustment of the nipple within the neck of the bottle. Alternatively, the sleeve may be formed of porous material.

The sine bar is fixed on a shaft 11 which carries a rotatably-mounted pinion 14 meshing with a rack 133 on the underside of the table; laterally-adjustable stops on the sine bar are settable by screws 21 to prevent or limit the reciprocation of the table when the pinion is turned by a handle 15. The machine is used primarily for dressing grinding wheels (see Division B3) by fitting a dressing tool carrier 16 to the table, a radiused edge being produced when the stops 9 lock the tables against reciprocation, and the pinion 14 is oscillated to rock the sine bar and cause the diamond tool 173 to sweep through an arc, and an angular edge being formed by inserting a peg 26 in registering holes 104, 129 in an upright 101 and a quadrant 125 forming part of the sine bar so that the latter is then fixed in desired angular position and then reciprocating the tables 13 by the pinion 14. Alternatively, for angular dressing, the sine bar is turned until one of the setting rollers 123 engages an appropriate gauge block positioned on a strip 102 on the machine base and a clamp 231 is then arranged to lock the quadrant 125 against the adjacent upright 101. In the use of the machine for work-setting or work-checking a gauge 31, Fig. 7, is mounted on the table 13 which together with the sine bar can then be adjusted as described above.
