Title: 球墨铸铁的高频等温淬火
IPC: C21D5/00
Filed: 1986-10-15
Abstract: 本发明提供一种新的球墨铸铁的热处理方法以及相应的球墨铸铁材料。其特点是：用高频加热、等温淬火的方法获得表面层为贝氏体组织，其余部分为铁素体基体或铁素体—珠光体混合基体的球墨铸铁。由于表面组织为贝氏体，所以表面韧性比马氏体高，裂纹倾向较小。方法是表面加热，节省了能耗，缩短了生产周期。由于内部不淬硬，所以比普通等温淬火又具有心部易加工，减噪性好的特点。因此这种材料对于仅仅表面受接触载荷的工件，从性能和经济方面考虑都是适用的。

Abstract: 1,047,423. Cooling and controlling reactors. INSTITUTT FOR ATOMENERGI. May 17, 1963 [May 18, 1962; March 22, 1963], No. 19719/63. Heading G6C. In a boiling water reactor, circulation of liquid and vapour is effected by a nozzle inside the reactor vessel which receives both pressurized water from an external source and liquid and vapour from within the shell. In the embodiments described, the reactor supplies steam directly to a turbine, the condensate from which is pumped back into the shell through the circulating nozzle. The action of the pressurized condensate has the effect of drawing water and vapour from the upper part of the vessel and discharging it, in the form of a jet, in the lower part, upwards through the reactor. Both the nozzles described incorporate mixing chambers where the condensate and the fluid already in the vessel are mixed. Reactivity control is effected by adjusting the pressure and temperature of the injected condensate so as to vary the coolant flow rate through the reactor core.

The assemblies A, B and C may be in one housing adjacent to the electrodes and remote from the assembly D. There may be more than two circuits each having a different value standard resistor, to extend the measuring range.

Abstract: 1,225,824. Making fibrous lace-like webs by film fibrillation. EASTMAN KODAK CO. 14 March, 1968 [20 March, 1967], No. 12367/68. Heading B5B. A fibrous product formed from an oriented film of a crystalline cellular thermoplastic synthetic organic material comprises a plurality of strands integrally connected with one another at points along their lengths, a plurality of fibrils integrally connected with one another and integral with and connecting adjacent strands between said points of connection, the strands and fibrils forming a lace-like web in which substantially all of the fibrils and strands have both their ends integral with and connected to the web whereby to provide less than 20 loose ends per square inch of web. The web may be twisted into cord-like form. The average diameter of the cells formed in the film may be not greater than the thickness of the film. The thickness of the film may be between 1À0 and 5À0 mils. The celular material may be a polyolefin such as polypropylene. The fibrous product may be made by melt extruding a mixture of the thermoplastic material and a small proportion (e.g. not exceeding 0À35% by weight) of a blowing agent to form a flat cellular film, stretching the film in the longitudinal direction at a draw ratio which is within the range of 3:1 to 15:1 and which is sufficiently high to render the film fibrillatable, and thereafter subjecting the oriented film to a fracturing force to separate the film into strands and fibrils. The stretching of the film may be effected in an oven maintained at a temperature within the range 300‹ to 375‹ F. The fibrillation of the film may be effected by subjecting the film to pulsating jets of air at 5-90 p.s.i. applied to both sides of the film at the same time.

Abstract: 1,227,758. Fuelling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 19 July, 1968 [16 Aug., 1967], No. 37819/67. Heading G6C. A fast reactor having a core 1 immersed in a pool P of liquid sodium in a vessel (not shown) has an annular store 16 for receiving new or spent fuel assemblies in sockets 23. The store 16 has a flange 18 at its upper end supported by bearings 19 whereby it may be rotated to align a selected socket 23 with an extension 21 of a charge/discharge machine 22. The machine 22 is carried by a rotatable shield 7 supported by bearings 10 and this shield remains stationary whilst the machine is operated whereby the machine may be used whilst the reactor is operating to transfer fuel assemblies between the sockets 23 and an external facility. A further fuelling .machine 24 is carried by a shield 8 rotatably mounted by bearings 12 in an eccentric aperture in the shield 7. After shut-down of the reactor an extension 25 of the machine 24 may be aligned with a selected part of the core 1 by rotating the shields 7, 8 whereby fuel assemblies may be transferred between the core and the sockets 23.

Abstract: 1,228,259. Vehicle roofs. M. F. ROBERTSHAW. 16 Oct., 1969 [18 Oct., 1968], No. 49647/68. Heading B7B. [Also in Divisions E2 and F4] A roof ventilator for a caravan, boat or building comprises a frame 12 each side of which is connected to a cover 8 by an adjusting mechanism. In the form shown, the frame 12 is positioned in a roof opening from below and a weather shield 16 is provided. In another embodiment, the frame is positioned from above and each side is of inverted channel-shaped cross-section. A drain water outlet may be provided for the channel between the frame 12 and shield 16. In another embodiment each adjusting mechanism is cam operated. The frame is made of extruded polyethylene or aluminium alloy and the cover 8 of transparent or translucent plastics material which may be tinted. A gauze screen may be provided for the frame.
