Thioether-group containing, branched chain, mercaptan-terminated polymers are made by pyrolysing a polymeric xanthate ester of formula wherein R is an aliphatic, aryl, aralkyl or alicyclic radical, M is a unit of the monomer or monomers employed in forming the said ester and represents, in homopolymerization, the unit of a conjugated diolefinic aliphatic hydrocarbon and, in copolymerization, the portion of the polymer molecule that contains mol. fractions of a conjugated aliphatic diolefinic hydrocarbon and vinyl monomer(s) copolymerizable therewith such that the sum of such mol. fractions is equal to one, and n is an integer from 5 to 120, the pyrolysis being terminated when the polymer viscosity reaches a Brookfield viscosity of 20,000-50,000 centipoises measured at 27‹ C. The starting polymer may be made by emulsion polymerizing the monomer or monomers by a conventional redox recipe in the presence of a large amount of a xanthate chain transfer agent. Thereafter the polymeric ester is pyrolysed by heating the solid polymer, optionally in the presence of a catalyst such as phosphoric acid.
Patent GB-188656-A (GB)
Title: Improved process for the chloridizing volatilization of metals
IPC: C22B1/08
Filed: 1922-11-06
Abstract: Oxide or roasted sulphide ores are heated by direct, preferably oxidizing, heating to or above the temperature required for chloridizing, and then removed to another furnace, without substantial loss of heat, and mixed with chloridizing material such as calcium chloride.  The second furnace is heated indirectly or by a limited amount of gas within it, and a current of air or combustion gas is drawn through the furnace, preferably in counter-current so as to remove the volatilized chlorides without undue dilution.  The charge is agitated, for instance by vigorous stirring, by fast rotation of the furnace, or by forcing or sucking air or gas through the ore.  Both treatments may be effected in rotary furnaces, and the second may be heated by burning gas in helical passages in the wall of the furnace, part only of the furnace being thus heated, while in a part contiguous to the discharge end the cooling of the material by the counter-current of air or gas is facilitated.  In an example, the treatment of a copper ore with calcium chloride is described, the temperature being 820 DEG  C.  Specification 188,657 is referred to.

Abstract: 1440723 Mechanical counter J HENGSTLER KG 9 July 1974 [18 July 1973] 30330/74 Heading G4D [Also in Divisions H3H and H1N] Counters are detachably mounted in a main frame by means of adapters the counters being formed with code elements which co-operate with code detecting means in the adapters to prevent the insertion of a counter into the wrong section of the main frame. The counters can be removed to a reading station and have means whereby they can be read automatically. Each counter has a plurality of number wheels 1, 14, 15, 16 rotating in the same plane with transfer gearing 23-28 between them and a ratchet mechanism 12 and gears 13, 17-21 for resetting each wheel. The lower face of each number wheel is formed with cam surfaces (Fig. 1, not shown) which co-operate with an array (Fig. 3, not shown) or pins slidable in the bottom wall of the counter casing; when the counter is at the reacting station the pins co-operate with the plungers of switches 11 to signal the state of the counter. Further pins may be included in the wall of the counter and co-operate with a coding plate to signal a counter identifying code (Fig. 6, not shown). When the counters are inserted in the main frame, a drive wheel 22 of the counters co-operate with a gear 47 within the frame. The counters are held in the frame by means 48. The wrong counter is prevented from entering the various sections of the main frame by respective corresponding pins and notches 51-54. The switches at the reading station are formed on a printed circuit board (39, Fig. 7, not shown).

Title: Improvements in ribbon vibrator mechanisms for typewriting machines
IPC: B41J35/00
Filed: 1922-11-07
Abstract: 210,857. Brougham, F. J., (Addograph Co.). Nov. 7, 1922. Ink-ribbon mechanism; driving-mechanism.- A ribbon-vibrator, which may be adjustable for multicolour, stencilling, and case-shift, is actuated by a spring, and is retracted in opposition to the spring by means of a rotary motor. The vibrator 27 is carried by a bell-crank 28 engaging a push-bar 34 connected to a rocking frame 25 which is associated with the key-controlled devices described in Specifications 25038/13 and 210,894 for actuating type-levers, the devices comprising an actuating-spring 26, and a ratchetcoupling on a shaft driven by a rotary motor. On depressing the keys, the rocking-frame is released and actuates the vibrator and type-levers, whereupon the ratchet-coupling is thrown in, and theparts are retracted by means of the motor. A spring 36 retains the bell-crank in engagement when the push-bar is retracted, and serves also to cushion the forward movement of the pushbar. To compensate for platen-shift, a pivoted arm 31 supporting the bell-crank is connected by a link 38 to the push-bar 34, and by a link 39 to a member of the shift-mechanism, for instance to the rock-arm 40, forming part of the shiftmechanism described in Specification 208,767. For two-colour adjustment, the push-bar can be moved laterally to place either of two fingers 44 thereon in engagement with the bell-crank; or for stencilling, the push-bar is moved into a mid-position, neither finger being then in engagement. The push-bar is moved by means of a slide 47 which is actuated by a cranked shaft 48, and is formed with a slotted arm 46 engaging a finger 45 on the push-bar. The cranked shaft is operated by a knob having a finger arranged over a colour-indicating plate. The slide is provided with projections 47a for engaging a detent.

Title: Improvements in or relating to the manufacture of hydrocarbons and other products from carbon monoxide and hydrogen
IPC: C07C29/156
Filed: 1937-11-06
Abstract: 505,121. Synthesis of methane from carbon monoxide and hydrogen ; catalysts. DREYFUS, H. Nov. 6, 1937, No. 30509. [Class 1 (i)] [Also in Group IV] In the synthesis of methane from carbon monoxide and hydrogen the catalyst is submerged in a liquid which' boils completely within the permissible range of reaction temperatures under the pressure employed or partly within this range and for the rest above it. Part of the liquid vaporizes, the vapours being condensed, e.g. in a reflux condenser, and returned to the reaction zone. As the liquid medium, hydrocarbons may be employed, e.g. a purified petroleum fraction or an oil obtained by reduction of carbon monoxide. Nickel catalysts at 230-250‹ C. may be used, e.g. nickel activated with alumina, prepared as described in Specification 465,157. Similarly prepared cobalt or iron catalysts yield liquid hydrocarbons. The reaction temperature can be regulated by adjustment of the pressure and thereby of the boiling point of the liquid medium. Preferably the ratio of hydrogen to carbon monoxide is greater than 1, e.g. 2: 1 to 4 : 1, by volume. Nitrogen, carbon dioxide or hydrocarbons, e.g. those boiling below the reaction temperature and produced from carbon monoxide and hydrogen, may be added as diluents in amounts of say 1¢-10 or more volumes per volume of carbon monoxide. The gases may be passed through a plurality of catalyst zones or recycled through a single zone. Specification 468,434 also is referred to.
