Patent GB-954342-A (GB)
Title: Aircraft heating system
Inventor: GOODE ARCHIE E
IPC: B64D13/08
Filed: 1962-11-02
Abstract: 954,342. Ventilating aircraft; heating aircraft. LOCKHEED AIRCRAFT CORPORATION. Nov. 2, 1962, No. 41515/62. Headings F4U and F4V. A warm air heating system for an aircraft compartment heats both the interior and the floor of the compartment. As shown, hot compressed air bled from the engine compressors passes through a gallery line 3 to a valve 5, which maintains a substantially constant mass flow into the heating system, and then into branch ducts 6 and 7. Branch 6 is controlled by an " on-off " valve 8 and leads to further branches 10 and 11 located in a chamber 13 beneath the floor 14 of the compartment being heated. Branches 10 and 11 each have a jet pump 12 drawing in a secondary air flow from the chamber 13, the mixed air passing into manifolds 15 for discharge through nozzles 18 into a shallow space 16 formed between the compartment floor 14 and a panel 17 constituting the top of the chamber 13. Some of the air then passes back to the chamber 13 through holes in the panel 17, while the rest passes into the main compartment through side vents. The branch 7 has a throttle valve 9 and leads to a cooling unit 22 having a by-pass line 23 controlled by a valve 24 which operates in response to signals from a thermostat 28 to maintain the compartment temperature substantially constant. Air from the cooler 22 and by-pass line 23 passes to an overhead manifold 26 in the compartment, and through nozzles 27 into the compartment. A thermostat 30 in the chamber 13 controls the valve 9 so that if more hot air is required for floor heating, the valve 9 will move in a closing direction, and vice versa, thus avoiding throttling the air supply to the jet pumps 12, which need the maximum supply pressure for efficient operation. An orifice in the throttle valve 9 ensures a minimum air flow in the branch 7 at all times. The valve 8 is controlled by an " on-off " switch, so that if the floor is not to be heated, all the air passes to the branch 7 for compartment heating. Air from the compartment is exhausted to ambient through a relief valve 31.

Title: Improvements in the treatment of cotton yarns and threads
IPC: D06M13/252
Filed: 1962-11-12
Abstract: The tensile strength, lustre, dye receptivity, smoothness, antistatic properties and crease resistance of yarns and threads are improved by immersing them in an aqueous colloidal dispersion of silica and then subjecting them while in the wet condition to the caustic soda of a mercerization bath so that the yarns and threads are mercerized and the silica simultaneously deposited thereon.  The colloidal dispersion which preferably contains 1% by weight of silica may be maintained at a temperature of 200 DEG F. and a pH of 11.  The colloidal silica bath may contain 0.1-5% by weight of a wetting agent, e.g. the sodium salts of alkylated benzene sulphonates, sodium lauryl sulphate, the sodium salt of methyl stearamide ethionic acid, dioctyl sodium sulphosuccinate and higher sodium alkyl sulphates, e.g. C4H9CH (C2H5) C2H4CH (SO4Na) C2H4-CH (C2H5)2.  Instead of or in addition to adding a wetting agent to the colloidal silica bath the thread or yarn may be passed through squeeze rolls to enhance the impregnation step.  The yarn or thread may be treated with a bath containing 1% by weight of caustic soda and a wetting agent and rinsed with water at 190 DEG F. prior to treatment in the colloidal silica bath having a pH of 9.8 and mercerization. Alternatively the yarn or thread may be first treated with water at 190 DEG F., treated with the colloidal silica, then treated with a 1% by weight caustic soda solution and mercerized or first treated with a 1% by weight aqueous solution of a wetting agent at 150 DEG F., treated with the colloidal silica bath at 190 DEG F. and mercerized.  Prior to, during or after treatment with the colloidal silica but before mercerization the yarns or threads may be treated with the alkali metal or magnesium salt of an inorganic acid, e.g. sodium chloride, magnesium sulphate, magnesium phosphate and sodium phosphate, a higher fatty amine salt, a quaternary ammonium, sulphonium and phosphonium compounds or an alkali metal salt of an ethylene diamine tetracarboxylic acid.  Yarns and threads comprising cotton alone or blended with other fibres, e.g. viscose rayon, may be treated.
