Abstract: 1479305 Furnace for cracking hydrocarbons STONE & WEBSTER ENG CORP 4 Oct 1974 [6 Nov 1973] 43232/74 Heading C5E A furnace 2 for thermally cracking hydrocarbons to produce olefins comprises process tubes through which the feed passes from the convection heated section 4, through a crossover section 8 and thence through the annular chamber 52 of the radiation-heated section 6; the radiation section is heated by a long flame burner 44 from which combustion gas is passed through the passage 58, through the chamber 52 (which has a cross-sectional area which decreases towards the burner 44), through the cross-over section 8 and through the convection section 4 to the outlet 22. As shown, the process tubes from the radiation section 6 pass into the annular chamber of a quench section 62 and the cooled cracked gases leave the furnace via the manifold 60; the combustion gas leaves the chamber 52 (e.g. at 1500 F.) and pass through the cross-over section 8 and through the convection section 4 together with combustion gas from the burner-32. Fig. 5 (not shown) illustrates ancillary apparatus in which the combustion gas (e.g. at 1200 F. and 5-15 atm.) leaving from outlet 22 is used to produce high pressure steam and is then used to preheat the hydrocarbon feed before being used as the quench medium in the quencher 62. Following use as quench medium, a portion of the combustion gas is passed to the burners 44 and 32 and a further portion is passed to a burner which powers a turbine. The cracked gas from the quencher is used to further preheat the hydrocarbon feed and then to produce steam for diluting the feed to be cracked.

Title: Improvements in or relating to processes for preparing tubeless pneumatic tyres for use and means for carrying out the process

Abstract: 1,249,175. Inflating pneumatic tyres. SCOVILL MFG. CO. 20 Sept., 1968 [20 Sept., 1967], No. 43991/68. Heading B7C. [Also in Division F2] A process for assembling a tubeless pneumatic tyre on a wheel rim includes the steps of mounting the tyre on the rim, the latter having a valve-stem-receiving opening with air-tight obstruction means blocking the opening, filling the tyre with air without disturbing the obstruction means, and engaging the obstruction means with an end of a valve stem to unblock the opening, and mounting the valve stem in the opening without permitting the escape of a substantial amount of air. The obstruction means may consist of a rubber grommet 12, Fig. 1, closed by a diaphragm portion 16 and having a groove 14 to engage the opening in the wheel rim. A brass or rigid plastics insert 18 has an internal thread 22 to receive a threaded projection 38 on the valve 34 after the latter has pierced the diaphragm 16. A skirt 36 clamps the upper end of the grommet against the insert when the valve is screwed home. The valve may have a projection 86 of a different shape as shown in Fig. 5 to pierce a diaphragm extending across the grommet below the insert 72. In place of the grommet, a thin metal disc 122, Fig. 9, may be adhesived or soldered to the rim 120 which is pierced by an extension on the valve, the extension having a slot 130 to form abrupt edges and corners. A rubber plug 144, Fig. 11, which is dislodged by a projection 148 during assembly of the valve or a rubber cup fitted within the boss 142 and pierced by a pin on the valve may be used. A rubber cap may also be used to enclose an inwardly projecting boss or a plug 204, Fig. 17, with a conical indentation 206 may be inserted in an opening 202 in the rim to be dislodged by a projection 208 on the valve 210. An 0-ring abuts a shoulder 216 to form a seal.

Abstract: 1,094,229. Automatic circuit breakers. GENERAL ELECTRIC CO. Oct. 19, 1965 [Oct. 22, 1964], No. 44182/65. Heading H2B. The bimetal tripping device of an automatic circuit breaker is arranged to compensate, at least partially, for the ambient temperature by coupling the bimetal 28 to the releasable latch 22 by a member 35 attached at one end to the free end of the bimetal and extending from the one end towards the fixed end of the bimetal so that upon a uniform increase in temperature of the bimetal clue to ambient conditions the latter bends so that the free end of the coupling member 35 moves further away from the bimetal and therefore does not trip the latch 22. On the other hand if heating is due to excess current the bimetal is heated non-uniformly the non- current carrying parts 34, 35, 36 acting as heat sinks while the conducting strap 29 acts as a heater so that the upper part of the bimetal bends rather more than the lower part and the free end of member 35 does not move appreciably away from the bimetal and thus the latch is released. In a modification (Fig. 6, not shown) the connection 36 is made part way along bimetal 28 so that only the upper half carries current. The bimetal carries a magnetic core 34 co-operating with an armature 25 formed on the latch member to release the breaker on short circuit. The core 34 may carry a wound coil in series with connector braid 36. In a modification (Figs. 7-10 not shown) the coupling member 35 forms the electromagnetic armature.

In a centrifugal strainer in which material for filtering is delivered by a pipe 41 to the lower end of a rotating frusto-conical filter basket 12 and solids are discharged over the upper end of the basket, the separated liquids thrown centrifugally from the basket are divided into two by means of a surrounding cylindrical wall 49, and wall 49 comprises an upper section 53, vertically telescopable about lower fixed section 52, whereby the relative proportions of the regions of basket 12 from which the two liquids are obtained may be varied. In centrifuging mossecuite, for example, it is arranged that green syrup is collected in compartment 50, inside wall 49, while wash syrup, produced by the action of wash water from spray 47 on residual crystals in the upper part of the basket, is collected in outer compartment 51. Upper section 53 comprises concentric shells 54, 55 joined by an upper ring 56 to define an annular space in which lower section 52 is received. Upper section 53 is vertically moved by three levers 64 spaced around the outer casing 18 of the strainer, which co-operate with scales and may be locked (Figs. 5, 6, not shown), and which turn shafts 59 bearing pulleys 58 round which are wrapped cables 61 attaohed at vertically spaced locations to section 53 (Figs. ,7, 8, not shown).
