Title: Tubular Combustion Chamber.
Inventor: TYRRELL ALBERT RALPH
IPC: H02K44/12
Filed: 1966-08-06
Abstract: 1,195,023. Heat exchange tubes. ROLLSROYCE Ltd., and CENTRAL ELECTRICITY GENERATING BOARD. 7 Aug., 1967 [6 Aug., 1966], No. 35294/66. Heading F4S. [Also in Division F1] A tubular combustion chamber constructed from flat-sided tubes extending longitudinally of the chamber and sealingly secured together side-by-side throughout their lengths has an upstream end perpendicular to the longitudinal axis of the chamber and a downstream end oblique to this axis, the tubes being shaped to define the longitudinal profile of the chamber so as together to define the cross-sectional shape of the flow path of the chamber throughout its length and also having cross-sectional shapes and flow areas differing along the lengths thereof. Fig. 1 shows a combustion chamber for an MHD power plant, having a square upstream end and a rectangular downstream end, the latter being inclined at 45 degrees to the longitudinal axis of the combustion chamber. The transition between the two shapes is produced by decreasing the height while maintaining the width substantially constant. The combustion chamber is formed from flat-sided tubes 1, 2  welded or brazed &c. together along their abutting sides, coolant (e.g. water) being passed through the tubes to a common downstream manifold. Structural and bursting loads are taken by an outer casing (not shown) bounding the tubes. The reduction in height between the upstream and downstream ends of the combustion chamber is accommodated by tapering the tubes 2 over the region EF (see also Fig. 10) to change their cross-sectional shape from that shown in Fig. 11 to that shown in Fig. 12. To allow for the fact that the tubes 2 of the far side wall of the combustion chamber are shorter than those on the near side, they are supplied from an inlet manifold with coolant at a lower pressure than that supplied from a separate inlet manifold to the near side tubes 2 and the tubes 1. The tubes 1 are of constant width but they are tapered in height over the region BD, Figs. 1 and 5, by the introduction of a depression 4, Figs. 6 to 9. Variation in length of the tubes 1 is compensated for by varying the position of the point B, as indicated by the oblique chain line, in Fig. 1. The downstream ends of the tubes 1, 2 are curved outwardly (as shown in Fig. 1 for the tubes 1) to reduce turbulence of the coolant flow into the downstream manifold (not shown). A tube 3 forming part of the wall of the manifold forms a downstream continuation of the outwardly curved ends of the tubes 1 and the tubes 2 of the far side wall of the combustion chamber to assist in turning the coolant into the manifold. Coolant, e.g. water, is passed through the tube 3.

Filed: 1922-12-29
Abstract: 213,334. Frost, W., and Frost & Co., Ltd., H. Dec. 29, 1922. Automatic circuit-breakers.-In thermostatically-controlled apparatus the time during which the heat is applied is regulated by the combination with the heat-generator and its controlling thermostat of a supplementary controlling-device which is automatically operated to diminish or stop the supply of heat after a predetermined number of operations of the thermostatic controlling device. In the arrangement shown, the supply of electricity to the heater 1 is controlled by a switch 3, 5 operated by a capsule or other form of thermostat, while the supplementary controlling-device consists of a switch 7, 8 normally held in a closed position by a spring controlled detent 11, but adapted to be opened after a predetermined number of operations of the switch 3, 5 by a spring 10 which comes into action when the detent 11 is swung aside through the medium of a cumulative mechanism such as a pawl and ratchet wheel 15, 16 carrying a pin 18 adapted to engage the detent 11 and to be set to any required initial position. A lamp, bell and similar indicator 20 may be actuated by the opening of the switch 7. 8. Owing to the fact that, if the rate of cooling is rapid, the apparatus will cool quickly when the heater is off and heat up slowly when the heater is on, while, if the rate of cooling is slow, reverse conditions hold, the time during which any required temperature is maintained is approximately proportional to the permitted number of operations of the thermostat. Specification 191,143, [Class 70, India-rubber &c.], is referred to.

Title: Improvements relating to hydraulic apparatus for lifting, lowering and supporting winding beams in textile machines
IPC: D02H13/38
Filed: 1953-12-22
Abstract: 745,418. Lifting and supporting web rolls. SUCKER GES., GEB. Dec. 22, 1953 [Jan. 2, 1953], No. 35580/53. Addition to 745,164. Class 100 (1). [Also in Group XXIX] An hydraulic apparatus for lifting, lowering, and supporting a textile winding beam and compacting the material wound thereon has a telescopic piston that applies the lifting, supporting and compacting force to the surface of the wound textile material, the supporting and compacting force being transmitted from the piston to the surface of the wound material through a device which includes a valve which relieves the hydraulic pressure acting on the piston when this force exceeds a predetermined value. A cylinder 1, Fig. 1, has a telescopic piston comprising sections 2, 3, the top section 3 carrying a slidable head 4 provided with a ball 4A which engages a wound roll supported in fixed bearings during winding. An escape pipe 6 is connected to the section 3 and to a pipe 7 leading to a reservoir 8. Hydraulic liquid is supplied from the reservoir 8 via a hand pump 9 or an electric pump 10 to the cylinder 1. The section 3, Fig. 2, has a base-plate 11 having a seating 13 for a valve 12 urged upwardly by a spring 16 engaging a nut 14 threaded to the stem of the valve 12. If a force in excess of the loading of the spring 16 acts on the head 4 the valve 12 is moved from its seating 13, thus allowing liquid to pass via a passage 15 to the pipe 6. Thus, the valve 12 remains depressed until the force acting on the head decreases sufficiently to allow the valve 12 to lift. The spring pressure may be adjusted by rotating the nut 14 by means of a bar inserted in a bore 17. Alternatively, the pressure at which the valve 12 opens may be controlled in accordance with a variable quantity, e.g. diameter of the roll being wound as determined by a feeler engaging the roll. Instead of causing an adjustment of the nut 14, the feeler may cause an adjustment of a regulating valve in the escape pipe leading from the valve 12, thus varying the back pressure exerted on the valve 12. A three-way valve 21, Fig. 1, controls lifting, lowering, and supporting and compacting, such that during lifting the escape pipe 6 is connected to the pipe 7, during supporting and compacting the pipe 6 is connected to the pipe pumps 9 and 10, while during lowering the pipe 6 and pumps 9 and 10 are connected to the pipe 7. An air vessel 18, Fig. 1, is included in the pipe between the pumps 9 and 10 and cylinder 1 to absorb shocks caused by irregularities in the winding of the roll.

Title: Method for purifying crude benzene
IPC: C07C7/00
Filed: 1953-12-22
Abstract: Crude benzene comprising about 5 per cent of impurities is purified by contacting with strong sulphuric acid, separating, contacting the acid treated benzene as a liquid with alkali metal hydroxide at a temperature within the range of 250-350 DEG  F. for at least 20 minutes, and distilling the thus-treated benzene in a distillation zone in which a bottoms fraction containing contaminants, higher boiling than benzene, is removed, and a side stream containing a higher purity benzene is withdrawn as product. In an example, a crude benzene containing 4.5 per cent of olefines, and 0.5 per cent of paraffins was initially treated with 30 lbs. of 98 per cent H2SO4 per barrel and after removal of the acid sludge, the benzene was treated at 265 DEG  F. under pressure so that it was still liquid with NaOH of 20 DEG  B<\>e for 30 minutes.  After settling, the benzene layer was treated in a distillation column at a pressure of less than 2 atmospheres absolute, 5 per cent by volume of flux oil being added at the base of the column.  The benzene was withdrawn as a side stream with a purity of 99.8 per cent and the aqueous impurities passed off as an overhead stream, and the bottoms, containing up to 1 per cent of benzene, could be reworked.
