Abstract: 552,187. Window opening and closing apparatus. WILMOT-BREEDEN, Ltd., and BREEDEN, C. L. Dec. 9, 1941, No. 15883. [Class 20 (iii)] [Also in Group XXXVII] Electrically operated means for opening and closing a window, and adapted for use on road vehicles, comprises an electric motor d operating the window b through mechanism a, the motor being controlled by a manual switch f and a delayed action automatic switch arranged in series, the latter interrupting the supply of current to the motor after the window has reached its fully closed position. When the reversible switch f is operated to raise the window, a contact I is closed, and current from the source e passes through a coil j heating a'deformable strip g which separates the contacts h, i, and breaks the circuit through the motor d. The switch I may be dispensed with, and its leads connected as at x. In a modification, the thermally operated switch may be replaced by an electromagnetic switch.

Title: Improvements in the production of metallic bodies
Inventor: WORN DAVID KENNETH
IPC: C22C1/10
Filed: 1960-05-12
Abstract: In the production of a metallic body consisting of an alloy hardened by a dispersion of fine particles of a non-metallic phase, particularly an oxide, and in which a minor proportion of the matrix alloy is a metal or metals which form oxides having at 18  DEG C. a heat of formation in excess of 80 K.cal./gm.atom of oxygen, small porous agglomerates of a powder mixture of the non-metallic phase and the major component of the matrix alloy are heated in the presence of vapour of the minor component or a compound thereof and in the absence of oxygen whereby the minor component is caused to deposit on and diffuse into the major component.  The mass is then consolidated. Metals used in the initial powder mixture may be nickel, cobalt, molybdenum, iron, copper or tungsten and elements deposited thereon may be chromium (which may be deposited from the fluoride), aluminium, silicon, beryllium, magnesium, cerium and carbon.  The dispersed phase is generally an oxide such as that of thorium, aluminium, magnesium or rare-earth metals, but other materials inert to the matrix such as sulphides of cerium, thorium, calcium, and molybdenum disilicide.  The initial powder mixture is preferably made mechanically as by ball-milling, but may be obtained by partial reduction of mixed oxides, as by reduction in hydrogen of mixed oxides resulting from the ignition of mixed calcium and nickel formates.  The agglomerates may be produced by compacting the powder mixture by pressure or by light sintering at 400-1000  DEG C., followed by crushing to a particle size preferably of 500-800 microns.  A further treatment at 400-1000  DEG C. in a reducing gas preferably follows to eliminate oxygen. The rate of deposition of the minor matrix component should not be greater than the rate of its diffusion into the major component; the former rate may be controlled by the admission of inert gas into the vaporization zone.  As exemplified, nickel powder and thoria were ball milled together, compacted at 35 tons/sq.inch, and crushed.  The agglomerates were then mixed with chromium granules of substantially greater size, and heated in a rotary cylindrical furnace for 16 hours at 400  DEG C. in dry hydrogen.  The furnace was then evacuated, argon admitted to a pressure of 50 mm. mercury and the temperature raised to 1200  DEG C. for 60 hours.  The mixture was then sieved to remove the chromium granules, consolidated at 35 tons/sq. inch, sintered at 1200  DEG C. in hydrogen for 16 hours, sheathed in nickel and extruded at 1100 DEG C.
