Title: Improvements in gas producers
IPC: C10J3/72
Filed: 1942-03-24
Abstract: 554,053. Fluid-pressure servomotor-control systems. POWER-GAS CORPORATION, Ltd., RIXON, F. F., and RUSCHIN, K. March 24, 1942, No. 3864. [Class 135] [Also in Group XII]  The control of operating variables such as the air, steam or fuel supply to a gas producer is effected by use either of the pressure in the air blast, or in the clean producer gas, by allowing leakage of a variable amount of the air or gas to occur through a pilot valve, operated in accordance with variations in the variable, which pilot valve controls indirectly a regulating device for the variable, said regulating device being actuated either by the air blast, or the producer gas. A gas producer 1 having a jacket boiler 2 and gas outlet 4 is supplied with an air blast from a blower, steam being fed to the blast through a valve 9 automatically regulated by the air blast under the control of an expansion element 31 in the blast main. The element 31, by a Bourdon tube 32, opens or closes a valve 33 which allows a proportion of the air to leak to atmosphere and, with the valve closed, the air pressure exerts maximum pressure on a diaphragm 11 which throttles the valve 9 admitting steam to the air blast. Thus, with increase in blast saturation temperature, less steam in proportion to air is admitted and vice versa. Air from the blast main passes at 27 to a diaphragm chamber 15 and control valve 26 operated by diaphragm 24 under the influence of pressure from the gas outlet 4. Thus, an increase in pressure at the outlet decreases the air flow through valve 26, increases the pressure on diaphragm 16 and throttles valve 14 in the air flow main. In a modification, the temperature of the outgoing gases may be made to control the fuel supply, and the carbon dioxide content the steam supply to the air blast. In this case the pyrometer needle and the carbon dioxide recording needle are each connected to a disc 64 free to move between nozzles 68, 69, nozzle 68 being connected to a pressure gas supply, and nozzle 69 to diaphragm chambers, so that interruption of the jet by movement of disc 64 controls the pressure in pipe 69 and in the appropriate diaphragm chamber.

Abstract: 879,521. Preserving timber piles. LIDDELL, O. E. Feb. 4, 1959, No. 3982/59. Class 68(2). A method of protecting timber from marine borer attack by limiting the circulation of water around the timber to a rate insufficient to maintain marine borer life within the vicinity of the timber, comprises enclosing the timber in a continuous sheath. Fig. 1 shows a pile 22 being encased by a sheet B cut off a roll of p.v.c., rubber, neoprene or woven fabric and which finally extends from above the water level to about two feet down into the sea bed. On each edge of the sheet is a bead 28 so that the two edges of the sheet can be gripped by a corrosion-resisting metal tubular member 30 with a longitudinal slot which is an easy fit over the double sheet thickness but is less in width than the combined thickness of the double bead. A space 38 is cleared by jetting, the sheath is slid down the pile and tightened on to the pile by rolling the tubular member, in the direction of the arrow in Fig. 4, to take up any slack. The member 30 is fixed in position by a pin 40 (Fig. 5 not shown). In a modification the sheet is cut to length before fitting to the pile and has a'rigid reinforcement of semi-circular cross-section attached to each long edge. The ends of the reinforcements are fitted into sockets at top and bottom so that the edges of the sheets can be rolled round as before to tighten the sheath, and pinned to prevent further movement. An additional piece is also provided on the lower end of the sheath to wrap round the pile and protect the lower end of the pile and reinforcing members.

Abstract: 1,040,531. Dispensing milk bottles. WESTINGHOUSE ELECTRIC CORPORATION. Feb. 3, 1964 [Feb. 25, 1963], No. 4488/64. Heading B8S. In a vending machine having three stacks of milk bottles B, a stack of bottles rests upon two bars 15 carried by levers 16 pivoted at 17 and connected by levers 19 to bar 18 so that vertical movement of the bar 18 causes consequential movement of bars 15 to release a bottle. Actuation of bar 18 (Fig. 5, not shown).- Frame 26 is reciprocated by a motor to move in a vertical direction. Additionally, solenoid 33 is energized so that its rod 36 by engagement at 34 causes lever 30 to rotate about 29 to bring finger 31 into aperture 32 of bar 18. Consequently as frame 26 moves fingers 31 engages the end of slot 32 to cause the upward movement of bar 18. This releases a bottle. In order to ensure that bar 18 does not move when not required claws 43 are provided pivoting at 42 on fixed member 21. The claws 43 are also provided with spring 44 and abutment 46. Normally claws 43 engage in recesses 45 in bar 18 to keep it fixed. However, during the said upward movement of frame 26 nose 31 engages abutment 46 to free claws 43 from the slots of bar 18 to permit the consequential movement of the bar, the claws falling into recesses 47 to hold the bar 18 at the end of its upward movement. When frame 26 moves downwards element 38 therein engages with element 37 on bar 18 to push the latter downwards, the bar being freed by the engagement of tabs 48 with claws 43. Additionally, de-energization of solenoid 33 pivots finger 31 to restore the mechanism to its original position. Should solenoid 33 fail to operate, finger 31 is restored to position by engagement with abutment 46 of claws 43.

Poly-(2,6-dimethyl- 1 4-phenylene ether) is obtained by (a) reacting oxygen with impure 2,6-xylenol containing 1 to 5% by weight of phenols other than 2,6-xylenol, while dissolved in a solution of an amine-basic salt complex until the polymer formed has an intrinsic viscosity of from 0À2 to 0À3 decilitres per gram when measured in chloroform at 25‹ C., (b) separating the polymer from the reaction mixture, and (c) dissolving the separated polymer in a solution of an amine-basic cupric salt complex and reacting the polymer in solution with oxygen until the required high molecular weight poly-(2,6-dimethyl-1,4-phenylene ether) is obtained. The impurities and their oxidation products remain in solution in the first step and are not present in the second oxidation so that higher molecular weight products may be obtained than would be possible if the impurities remained throughout the whole polymerization process. The oxidation in the first step may be carried out in a solvent in which the polymer is soluble, the polymer being precipitated when the intrinsic viscosity is the above range by adding a precipitating liquid, or the first step may be carried out in mixture of a solvent and a non-solvent for the polymer chosen so that the polymer precipitates when its intrinsic viscosity is between 0À2 and 0À3 decilitres per gram. In examples 2,6-xylenol containing impurities is reacted with gaseous oxygen in mixtures of toluene and isopropanol containing dimethylamine and cuprous chloride, the polymer precipitates, is filtered off, dissolved in toluene containing tetramethyl ethylene diamine, trimethylamine and cuprous chloride, and again reacted with gaseous oxygen to obtain the final polymer.
