Title: Improvements in or relating to the manufacture of vinyl chloride
IPC: C07C17/08
Filed: 1942-10-13
Abstract: In the production of vinyl chloride the by-products of the dehydrochlorination of ethylene dichloride (for instance as described in Specification 573,532) are partially, but not completely, freed from saturated organic chlorine compounds so as to reduce the content thereof to less than 15 per cent by volume of the gaseous product, and the partially purified hydrogen chloride so obtained is reacted with acetylene to produce more vinyl chloride.  The partial purification of the hydrogen chloride p  may be effected by cooling or by washing with a solvent such as vinyl chloride, toluene, xylene, and chlorinated hydrocarbons boiling up to about 150 DEG  C. including ethylene dichloride. Detailed examples are given.

Filed: 1927-05-28
Abstract: 272,203. Ducart, G. June 4, 1926, [Convention date]. Packeting by wrapping-up. - Relates to mechanism for folding wrappers over the ends of cylindrical boxes, tins, &c. The wrapper 25, Fig. 1, is applied to the box 24 so as to form a tubular covering extending at each end, and the whole is placed on a platform 27 so that the upper edge of the box is level with folding blades 13. Carriages 8 for the blades 13 move in radial slots 4 in a table 1 and are moved radially by the engagement, of pins 9 in cam slots 7 in a plate 5 adapted to be rotated by a handle 6. Each blade 13, Fig. 5, is mounted on a shaft 12 rotatable in the carriage 8 and is adapted to be turned through a right angle at the appropriate moments by the engagement of a pin 14 with a slot 18 - - 21, Figs. 1 and 9, in a plate 17. In use, after the box and wrapper have been placed in the position shown in Fig. 1, but with the upper edge of the wrapper still projecting upwards, and with the carriages 8 and blades 13 retracted to their outer positions, the handle 6 is turned so as to cause the carriages to move inwards. During the inward movement, the pins 11 engage the straight. portions 19 of the grooves and the blades therefore occupy vertical planes and form a number of pleats. Towards the end of the movement, the pins ride up the portions 21 and turn the blades down flat turning all the pleats dl - - d<7> into the positions shown in Fig. 15, the. blades momentarily lying between the folds so formed. The handle 6 is now moved in the reverse direction to retract the carriages 8. The pins 14 engage the upper straight portions 18 of the grooves and the blades therefore disengage themselves radially from the folds with a smoothing action, being turned again into a vertical position towards the end of the stroke by the action of the portions 20 of the grooves.

Title: Method and apparatus for automatically controlling a fuel cell
Inventor: WILSON JAMES ALLAN
IPC: H01M8/04
Filed: 1968-03-26
Abstract: 1,210,958. Automatic 'control systems for fuel cells. ESSO RESEARCH & ENG CO. April 26, 1968, No.14446/68. Heading G3R. A fuel cell operating with a liquid electrolyte wherein the fuel is dissovled has automatic control of the fuel supply to maintain the fuel concentration within a predetermined ranged compatible with a maximum permissible fuel cell current corresponding to a particular concentration. To this end a sample of the fuel electrolyte mixture in the cell is fed to an analyser cell 1 through which is periodically passed a current having a linear ramp function whose rate is dependent on the current passing through the fuel cell. During each current scanning period the voltage across the platinum electrodes 2, 3 is compared with a reference value which exceeds the electrode voltage when the peak current is on or below the characteristic relating fuel cell current to fuel concentration, Fig.1 (not shown), this condition corresponding to de-energization of a D.C. motor 9 which drives the fuel pump and is controlled by the voltage comparator and switch 6 through a circuit 7. Should the peak current exceed the characteristic during a scanning period (a condition producing severe anode polarization in the fuel cell), the electrode voltage exceeds the reference value and causes energization of the motor to supply fuel to the cell until the end of the particular current scanning period. The length of these periods and of the "OFF" periods between them is determined by a cycle generator 8 in the form of a low frequency multivibrator comprising a conventional arrangement of resistors, capacitors and transistors. Circuits 6, 7 and 8 together with the detector and amplifier 4 and the current scanning ramp generator 5 are described in detail, Fig.3 (not shown). The fuel cell may supply the D.C. power required for the control circuit of Fig.2.

Filed: 1965-04-06
Abstract: 1,103,962. Air-cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. 1 April, 1966 [6 April, 1965], No. 14614/65. Heading B7K. [Also in Division F4] A gas-cushion vehicle for operation over water has means for taking in water from beneath the vehicle and means for heating the water and means for raising the pressure of the water to prevent it boiling-off when heated and discharge means for discharging the heated and pressurized water into the cushion space whereby it flashes into steam. The craft 1, which may be propelled by water screws, is formed with sidewalls 6 which, with the bottom 23, enclose a cushion space 4, the space being sealed at both ends by water curtains. In alternative constructions the sidewalls may be flexible with provision for discharging water curtains (Fig. 6, not shown) or the walls may be flexible with water intake scoops and ducts spaced from the walls (Fig. 5, not shown). The rear water curtain may be dispensed with and a vertically-adjustable transverse baffle may be used to control the outflow of cushion gas, thereby providing a controllable propulsive thrust (Fig. 4, not shown). The system for generating cushion steam comprises a gas-cooled nuclear reactor 10, the cooling gas being helium circulated in two identical closed circuits 14 by pumps 15. Each circuit 14 includes a heat-exchanger 16 and pumps 15 are driven by gas turbines 46 using reactor coolant bled from circuits 14 by tappings 19. Water is drawn in through intake ducts 17 in the sidewalls by pumps 18 driven by gas turbines 47 and delivered through the heat exchangers 16 and ducts 22 to spray nozzles 24 in the cushion space 4 where it flashes into steam. In operation an air-cushion is initially formed by releasing high-pressure air from bottles 26 by means of valves 28 and subsequently the air-cushion is replaced by a steam cushion. In a further embodiment (Fig. 3, not shown), free water in the cushion in the form of spray is collected by scoops (30) and drawn through ducts (31) by pumps (32) to further heat exchangers (33) and thence to further spray nozzles (37) in the cushion space 4. The front and rear end curtains may be formed by steam instead of water.

Filed: 1920-06-01
Abstract: 146,939. Trent, W. E. June 25, 1919, [Convention date]. Generating by direct contact of combustion products. - In a process for treating ores, chemicals, minerals, and the like, broadly applicable to oxidizing, reducing, volatilizing, chloridizing, and other processes, by a heat treatment, or a combined heat and chemical treatment, the fineiydivided material is introduced directly into a heating blast, the nature, composition, and temperature of which can be regulated to meet the required conditions, and undergoes rapid treatment while travelling in suspension through the flame, after which the products are cooled by water and the gases separated from the condensed material. The drawing shows a convenient form of apparatus. An outer metal jacket 3 is widened at one end to form a cooling-chamber 4. An inner chamber 10 lined with fire-brick and having a metal casing 10<1> at one end and a thicker casing 13<1> at the other, is connected to an air pipe 7, oil pipe 8 and treating-agent pipe 9 with valves 7' and has a discharge-opening 15. Water under pressure is supplied through a pipe 9<1> to the chamber 4 and water-jacket 25 and passes out through a pipe 9<a>. Combustion of the fuel, which may be oil or pulverized coal, and air supplied by the pipes 8 and 7 is started by means of a spark-plug 16<1> and the temperature of the flame is regulated by the water-jacket 25 and the addition of water through a spray 27 controlled by a needle-valve 28. Finely divided material, preferably liquefied by the addition of water or fuel oil, is introduced through the pipe 29 and is carried along and acted upon, by the blast, containing any required treating-agent introduced through the pipe 9, through the treating zone XX. Water is added through the spray 30 controlled by the valve 31 and the mixture of steam, air and ore passes through the condensing coil to a tank 19 where gases are removed through a pipe 21 and sludge through, a pipe 23.

Abstract: 492,543. Coke - oven heating - flues. KRETZ, T. May 29, 1937, No. 14957. Convention date, May 30, 1936. [Class 51 (ii)] In a coke-oven heating-wall the heating-gases are directed from a metal-walled pressure chamber 5 through orifices 9 in a large number of high velocity jets which strike the metal heat-interchange wall 1 separating the heating- gases from the charge and rebound therefrom. In the movable heating-wall shown in Figs. 1 and 2 the gases enter and leave by the connections 3, 14 respectively and the chamber 5 is subdivided by vertical partitions 6. The walls 8 of the chamber 5 diverge from the outer walls 1, and the lower end of the chamber is stepped to provide for the increasing volume of heating- gases to be accommodated. The heating-wall may be built up of U-shaped sections 15, Fig. 3, and perforated metal inserts welded together. Alternatively the pressure chambers may be formed by one or two rows of perforated tubes inserted vertically in the heating-wall as shown in Fig. 6, the spaces 25 in this case serving for the escape of the heating-gases. The orifices 9 may gradually increase in size or their spacing may be decreased in the direction of travel of the gases, and they are preferably flared to decrease eddy current losses. The temperature of the gases escaping through the passages 12, 13 may be kept up by admitting gases direct from the pressure chamber.

Abstract: 497,312. Loom dobbies; pattern cards. MASCHINENFABRIK BENNINGER AKT.- GES. May 19, 1938, No. 14959. Convention date, May 21, 1937. [Classes 142 (i) and 142 (ii)] The shaft raising means A is located under the shafts 1 and the card apparatus Ka and the shaft driving means Sch at the side of the loom, the former above the level of the warp and the latter on the floor. A vertical shaft 51 driven by gearing 52, 53 from the crank-shaft K carries (a) a cam 64, Fig. 90, which with a spring 65 periodically lifts all the feeler levers 55, (b) a cam 66 for intermittently rotating the card drum 78 through reversing gearing 69, 74, Fig. 11, and 69, 75, 76, (c) a cam 50 for moving selected lifters 22, 221, Figs. 1, 3, away from the knives 23, 23<1>, and (d) a wheel 89, Fig. 11, for driving an eccentric 92 which through a lever 94 vibrates all the feeler levers 55 laterally so that they can read the zigzag rows of holes a ... e in the cards. Each lever 55 carries a feeler pin 57 and is lowered by a spring 59. All the feelers are mounted on the shaft 56 of a lever 62 and are raised together by a rod 60 and the cam 64. The shaft 56 is also turned to lift all the levers 55 by a lever 81, Fig. 13, and a cam 79 on the starting handle 72 when this is in the stop or the reverse drive position. The cam 50 oscillates a shaft 46 on which are pivoted a number of levers 45, one end of each of which is adapted to be engaged by a catch 54 on one of the levers 55 and the other end of which is connected by a rod 44 lever 43, rod 41 to a lever 40. When the pin 57 of a lever 55 enters a hole in the card 58 the catch 54 is lifted clear of the corresponding lever 45 and the cam 50 does not move the corresponding lever 40 and the corresponding shaft 1 is raised as described below. When the pin 57 of a lever does not enter a hole in the card 58, the corresponding catch 54 engages the lever 45 and the corresponding lever 40 moves a bar 36 horizontally. This bar carries pins 37, 37<1> which engage the cranked parts 35, 35' of the lifters 22, 22', so that they are clear of the oppositely moving lifting knives 23, 23'. These knives are oscillated about a pivot 26, vertically below the fell of the fabric being woven, by two eccentrics 32, 321 on the main shaft W, which act through levers 29 and adjustable rollers 27 on the hooked ends of the knives. The knives are mounted to slide at 25 on their pivot 26 and carry a roller 34 working in a guide slot 33, e.g. as shown, to ensure that the part of each knife at the middle of each bunch of lifters 22, 22<1> moves vertically in a straight line. Each pair of lifters 22, 22<1> acts on a cross lever 20 pivoted to one end of a lever 17 the other end of which is connected through a rod 16, lever 9, and rack 2 with one of the shafts 1. The shafts 1 are pivoted at 3 to their racks, and are guided between rods 5 and fixed and spring- pressed collars 6, 7 on these rods.
