Compact fast nuclear reactor using heat pipes

A fast nuclear reactor is described which comprises a conical reactor core surrounding an embedded array of heat pipes of, per se, novel structure, carrying either moderator or nuclear fuel material as part of their working fluid. This reactor system is self-regulating, because an excessive increase in reactivity drives the fuel or moderator working fluid out of the conical core region, thereby reducing reactivity. The heat pipes are protected against burnout by a novel heat pipe envelope shape and internal wicking structure designed to increase the working fluid circulation speed with increasing heat transfer loads.

Underground nuclear power station using self-regulating heat-pipe controlled reactors

A nuclear reactor for generating electricity is disposed underground at the bottom of a vertical hole that can be drilled using conventional drilling technology. The primary coolant of the reactor core is the working fluid in a plurality of thermodynamically coupled heat pipes emplaced in the hole between the heat source at the bottom of the hole and heat exchange means near the surface of the earth. Additionally, the primary coolant (consisting of the working flud in the heat pipes in the reactor core) moderates neutrons and regulates their reactivity, thus keeping the power of the reactor substantially constant. At the end of its useful life, the reactor core may be abandoned in place. Isolation from the atmosphere in case of accident or for abandonment is provided by the operation of explosive closures and mechanical valves emplaced along the hole. This invention combines technology developed and tested for small, highly efficient, space-based nuclear electric power plants with the technology of fast-acting closure mechanisms developed and used for underground testing of nuclear weapons. This invention provides a nuclear power installation which is safe from the worst conceivable reactor accident, namely, the explosion of a nuclear weapon near the ground surface of a nuclear power reactor.

Axial-flow fan

AXIAL-FLOW FAN Abstract An axial-flow fan comprises a stepped housing defin-ed by an inlet part and an outlet part, the outlet part having the inside diameter smaller than the inside dia-meter of the inlet part, the inlet part having adjoined thereto an inlet tube of an inside diameter substantial-ly equal to the inside diameter of the outlet part of the housing. The outlet part of the housing accommodates a ro-tor having blades arranged such that their forward tips are located in the inlet part of the housing, a ferrule being secured at a certain distance from the inlet tube coaxially with the housing to form with the housing an annular chamber having on the side of the rotor an inlet passage and on the side of the inlet tube an outlet pas-sage. Rigidly affixed in this chamber are guide vanes pointing by their heels to the inlet tube. The heels of the guide vanes extend to the inlet tube and are radial-ly curved at a portion between the inlet tube and the fer-rule to form an annular radial grill.

Temporary/portable nuclear fallout shelter

ABSTRACT OF THE IVENTION Significant, life-saving protection from airborne, radio-active (fallout) particles due to nuclear explosions, nuclear reactor accidents, and other releases of radioactive particulate is provided by a double-wall tent structure quickly erectable over a central trench hole. The tent structure includes tight-ly woven, rip-resistant fabric panels supported by tensile rods or wands, a tub floor extending into and lining a central trench or hole, and an exterior, light-reflecting, metalized, semi-transparent disposable membrane. The bottom circumferential edge of the outer membrane extends into a shallow trench or-ditch, excavated around the perimeter of the inner tent structure. Dust particles settling onto the smooth exterior surface of the mem-brane slide off and are captured in the shallow ditch, thus minimizing direct or indirect radiation into the central trench or hole and its occupants. The perimeter of the outer membrane contains pockets for the storage of potable water and for anchor-ing of the outer membrane. The tub floor lining extending below the ground surface includes sealable pockets suitable for the storage of refuse and human waste during occupancy. Also de-scribed is a light-weight single membrane, plastic, portable tent, suitable for low-cost mass production.

Electroslag melting of shaped castings

ABSTRACT OF THE DISCLOSURE A method and plant for the electroslag melting of shaped castings by remelting a consumable electrode in a slag bath with the concurrent fusing of an element, at the initial stage the fusion process is carried out by introducing the element to be fused into the slag bath to 0.2-0.5 of the depth of the slag bath by using a consumable electrode with a cross section that is at least equal to that of the element being fused. The use of the above outlined method and plant make it possible to diminish materially the production costs in making shaped castings and to rule out welding from a technological process.

An elongate, longitudinally oriented outer sleeve includes an outer sleeve surface defining a radially oriented proximal sleeve border, a radially oriented proximal sleeve rim intersecting the outer sleeve surface at the proximal sleeve border, an outer sleeve body enclosed by the outer sleeve surface and the proximal sleeve rim, and an elongate, longitudinally oriented stem-receiving cavity formed in the outer sleeve body and intersecting the proximal sleeve rim to define a stem-receiving aperture. A joint articulating member includes an elongate, longitudinally oriented stem, an articulating surface, and an interface rim. When the stem is at least partially inserted into the stem-receiving cavity, the proximal sleeve rim and the interface rim interact to change a longitudinal relationship between the outer sleeve and the joint articulating member responsive to relative radially-oriented rotation between the stem and the stem-receiving cavity.

Method of fixing a fish as to the position thereof in a fish processing machine and a machine for performing said method

An apparatus and a method for separating fish heads from the remainder of the fish are provided. The apparatus includes a cutting blade, a conveyor movable in a predetermined path past the cutting blade and tapered pins extending through and each having a free end protruding from the conveyor. The pins gradually narrow along the direction towards their free ends. The free end of each pin passes through the eyes of a fish to thereby fix the position of the fish relative to the cutting blade. The feature of tapering determines how far along the length of the pin the fish will be impaled; a smaller fish with relatively smaller eyes will be carried on the pin at a relatively higher level above the conveyor than a larger fish. Such a variation of the positioning of the fish relative to the size of the fish promotes considerable conservation of the food quality portions of the fish body as wastage is more exactly limited to the discarding of the head. A method for separating the fish head from the remainder of the fish is also provided.

System for providing lift and propulsion to an air cushion vehicle

The system for providing lift and propulsion to an air cushion vehicle contains, according to the invention, an annular fitting (1) in whose inlet part an axial blower is arranged whilst a thrust jet (4) is attached to the outlet from the annular fitting (1). The thrust jet (4) is equipped with a reversing and control device (5) with independently adjustable control blades and reversing blades (8) which are arranged in the walls of the thrust jet (4) behind the axial blower. The side walls of the reversing and control device (5) are constructed as a multi-face grille-like surface which is formed by grilles (7), which are permanently attached in each individual face, of the reversing blades (8) with arcuate profile, the control blades shutting off the outlet cross-section of the thrust jet (4) during the thrust reversing process and forming an obtuse angle ( gamma ) with one another whose point faces the axial blower. The invention can be used with air cushion vehicles, automotive transport platforms and gear in which the propulsion is provided by thrust produced by the expelled jet of air. <IMAGE>
