Title: Improvements in or relating to the feeding of molten glass to shaping or forming machines
IPC: C03B7/092
Filed: 1920-01-23
Abstract: 161,001. British Hartford-Fairmont Syndicate, Ltd., and Bunge, J. H. 0. Jan. 23, 1920. Discharging. - Relates to a modification of the apparatus described in Specification 105,672 which adapts it to deliver automatically charges of molten glass to two or more machines requiring charges of different weights. According to the invention an auxiliary cam 9, positively driven from the main cam-shaft 3 is provided. A roller 10, adjustably mounted on the lever 6, is engaged by the cam 9, thus lifting the lever 6 and reducing the immersion of the paddle 1 in the molten metal and hence the weight of charge delivered by that particular stroke. The frequency of these reduced impulses can be varied by altering the ratio of gearing between the shaft 3 and cam 9.

Title: Modified zeolitic molecular sieves, their production and use
IPC: B01J20/18
Filed: 1964-01-20
Abstract: Three-dimensional crystalline sodium A zeolitic molecular sieve, which may be in the form of agglomerates, either with or without binding materials, for example sodium silicate or clay, is contacted with steam at a temperature of from 250 DEG  to 650 DEG  C. for 0.5 to 200 hours to give a steam-treated molecular sieve containing pores of a reduced apparent pore size, which pore size remains unaltered on heating to the activation temperature for sodium zeolite A.  The steam-treated sieve retains the water capacity and crystallinity originally possessed prior to steam treatment but has an oxygen adsorption capacity after reactivation of less than 10.6 weight per cent measured at -183 DEG  C. and 700 mm. Hg pressure.  During the steam treatment, the water vapour pressure of the steam should be greater than 25 mm. Hg for non-agglomerated sieve, greater than 25 mm. Hg and preferably greater than 100 mm. Hg for sodium silicate-bonded sieve, and greater than 700 mm. Hg and preferably greater than 760 mm. Hg for clay-bonded sieve.  After treatment with steam, the sieve or an agglomerate thereof is exposed to the activation temperature for sodium zeolite A.  The steam-treated sieve or an agglomerate thereof may be contacted with a gas stream containing water and halogenated ethane and methane derivatives to thereby adsorb water from the gas stream without decomposing the halogenated derivatives.ALSO:Water may be removed from halogenated and partially halogenated ethane and methane derivatives, whilst avoiding decomposition of these derivatives, by contacting a gas stream containing water and such derivatives with a steam-treated three - dimensional crystalline sodium A zeolitic molecular sieve, which sieve may be in the form of agglomerates, either with or without binding materials, for example sodium silicate or clay.  The treatment of the sieve with steam gives a sieve which retains the water capacity and crystallinity possessed prior to steam treatment but which contains pores of reduced apparent pore size, the reduced pore size remaining unaltered on heating the sieve to the activation temperature for sodium zeolite A.  The reduced apparent pore size allows selective adsorption of water to thus purify, for example, a refrigerant system containing halogenated hydrocarbon.

Title: Process for the production of sulphohalogenated polymers and co-polymers of olefins
IPC: C08F8/34
Filed: 1962-01-29
Abstract: Vulcanizable sulphohalogenated polymers of olefines are produced by reaction of a sulphuryl halide or a gaseous mixture of halogen and sulphur dioxide with solid finely divided polymer in the presence of a nitrogen containing organic compound as anti-static agent and at a temperature above or equal to the starting temperature of the endothermal fusion phenomenon of the polymer.  The homo- or co-polymers may be derived from ethylene, ethylene/propylene or ethylene/butene and may contain a filler, e.g. carbon black, or litharge, stearic acid.  The sulphohalogenation may be carried out in two stages, the polymer being partially halogenated at a temperature below the above endothermal temperature and then completing the conversion in the presence of the antistatic agent at a temperature above or equal to the above endothermal temperature. The antistatic agent, e.g. 0.5-5%, may be a quarternary ammonium salt or a tertiary amine, e.g. dimethyl benzyl lauryl ammonium chloride, dibenzoyl hexadecyl amine or CH3(CH2)xN[CH2CH2O)yH] [(CH2CH2O)zH] where x is 1-20 and y and z are each 2-25. The treated polymers may be vulcanized to produce microcellular sponges by incorporation of 2-3% of a swelling agent.
