Title: Improvements in or relating to fuel cells
IPC: H01M4/86
Filed: 1962-04-30
Abstract: A sintered fuel cell electrode or filter having a layer of fine pores and a layer of coarse pores of controlled porosity is formed by adding powdered carbon of the required fine particle size into a ring with a lip of the required depth of the layer, placing a second ring over the first assembly and adding powder of the required coarse particle size to this ring to form the second layer, compacting the two powder layers together and then sintering.  The powder may be compacted at 500-8,000 p.s.i. either by pressure or by vibration and sintering is effected at 1200-2400 DEG  F. in an atmosphere of 90% argon-10% hydrogen.ALSO:A sintered fuel cell electrode or a filter having a layer of fine pores and a layer of coarse pores of controlled porosity is formed by adding powder of the required fine particle size into a ring with a lip of the required depth of the layer, placing a second ring over the first assembly and adding powder of the required coarse particle size to this ring to form the second layer, compacting the two powder layers together and then sintering.  The preferred powder is Ni metal powder but metals of Group VIII and Ib of the Periodic Table and also carbon may be used. The powders are compacted at 500-8000 p.s.i. either by pressure or by vibration and sintering is effected at 1200-2400  DEG F. in an atmosphere of 90% argon-10% hydrogen.  The metal powders are selected with a particular mean particle size and size range which depends on the required pore size of the sintered product.

Title: Improvements in chucks
IPC: B23B31/00
Filed: 1943-10-12
Abstract: 568,227. Chucks and sockets; mandrels ; stud-boxes. THORNHILL, G. Oct. 12, 1943, No. 16694. [Class 83 (iii)] Chucks or mandrels for holding work - pieces having screwed engagement therewith are provided with a thrust member which takes the end thrust of the work during the operation and which is backed up by an abutment that can be moved to free the thrust member and permit easy removal of the finished work. The body of the chuck 1, Fig. 3, is fitted with a back plate 2, Fig. 1, for screwing onto the nose of the lathe &c. spindle. Mounted in a taper bore 3 is a mandrel 4 for receiving internally-threaded members, such as the rod 5. Externally-threaded work is screwed into a mandrel 4 that is internally threaded. In each case an interchangeable adapter 7 carried by thrust member 6 receives the end thrust. The member 6 has a limited movement on the body 1 as controlled by a slot and screw 16. Bores 10 in the body receive pins provided with cam heads 8 having tails 11. Flats 14 and 15 are at different distances from the axis, the flats 14 holding the member 6 forward in operative position. When the cams are rotated, the flats 15 allow the member 6 to recede, thus freeing the work 5. The tails 11 engage notches in a spring-controlled ring 13 that normally rotates all the cams into operative position. Rotation against the spring to cause release may be effected by rotating the ring directly or by rotating one of the cams as by a tappet head 23, the ring then transmitting rotation to the other cams. An arch-shaped member secured to the .lathe &c. headstock carries two trip pawls held in either operative or inoperative position by a spring-controlled slide. One pawl acts on each end of the tappet head 23, and when the work is to be released, the appropriate slide is pushed in, rendering the corresponding pawl operative, according to the direction of rotation of the work.

[Class 100 (ii).] In order to prevent deformation of the flexible flongs during casting of printing- surfaces, they are provided with a heat-resisting flexible backing composed of a vulcanizable material. The backing is mainly composed of rubber, guttapercha, balata, or the like, and can be applied either in the form of a plasticized sheet or an artificial or natural aqueous dispersion. In the former case, a thin unvulcanized sheet of rubber is placed on the back of the flong and the two are embossed together, vulcanization being ejected either simultaneously or subsequently. The aqueous dispersions may be applied by pouring, spreading, painting, or spraying, and may comprise dispersions of coagulated rubber, vulcanized rubber, synthetic rubber, waste, or reclaim to which known compounding-ingredients or concentrates obtained according to Specifications 290,313 or 291,635, may be added. In an example, a composition containing rubber, sulphur, zinc oxide, zinc diethyl-dithiocarbamate, barytes, and limestone dust is employed.

Abstract: Tolyl alkanes are made by continuously introducing toluene and a polymer boiling essentially between 338 DEG  and 437 DEG  F., and having the molar structure resulting from the polymerization of propylene to a reaction zone in the ratio substantially of from 0.8 to 4 molar proportions of toluene to one of polymer, reacting the polymer with the toluene in the presence of sulphuric acid containing 0 to 10 per cent by weight of water at a temperature of 0 DEG  to 70 DEG  F., preferably about 35 DEG  F., while the acid is maintained in the reaction zone in an amount substantially of 1 to 5 volumes per volume of hydrocarbons, and recovering the hydrocarbon reaction product.  Preferably reaction is effected at about 20 DEG  to about 50 DEG  F. and at a space time, i.e. the volume ratios of sulphuric acid and hydrocarbon feed charged per minute, of about 20 minutes to about 80 minutes.  Polymers are derived from the catalytic polymerization of propylene alone or with its simple polymers including hexenes and nonenes, preferably in the presence of a solid phosphoric acid catalyst at about 150 DEG  to about 350 DEG  F. and about 100 to about 200 p.s.i. pressure.  A preferred aromatic starting material is a straight-run naphtha containing at least about 10 per cent, preferably at least about 30 to about 70 per cent, of toluene.  Preferably the aromatic charge consists entirely of toluene and the aromatic olefine ratio is 1.5 to 4 molar.  High yields are obtained when from about 0.1 to about 0.8 parts by weight of fresh sulphuric acid catalyst is added per part of alkylating agent introduced.  Preferably the acid contains not more than about 6.5 per cent of water.  Used sulphuric acid isolated after stratification of the products in a settling zone is recycled.  Tables are given illustrating the beneficial results obtained when operating within the above reaction conditions.  Specification 666,642 is referred to.
