Abstract: This invention provides a novel bracket for shock mounting a bulb within a housing for a lamp that is particularly intended for use with motorized vehicles, such as over-the-road trucks and the like. Basically, the novel bracket of the present invention comprises: a serpentine strip having polygonal apertures provided at its opposite ends and a bulb-receiving socket generally centrally located therein, the radial center of which socket is offset from the long central axis that extends between the apertures in the strip. Preferably, the strip is connected to the lamp housing by fastener means, portions of which are respectively passed through the polygonal apertures in the strip and prohibit pivotal movement of the apertures thereabout. It is also desirable that the fastener means portions comprise a pair of studs projecting from the lamp housing and being complementary in size and shape to the polygonal apertures in the strip through which they are respectively passed.

Abstract: In a fast reactor having a diagrid structure supported on the bottom wall of a reactor vessel containing the core and liquid metal coolant, a core catcher serves in the event of core melt-down to prevent hot debris carried down by the liquid metal from coming into contact with the vessel walls. The core catcher comprises a single collecting tray having a large area, a central chimney and a bearing shell extending parallel to the bottom wall of the reactor vessel. An enclosed space is formed between the bottom wall, the diagrid support structure and the diagrid and contains the collecting tray. Under melt-down conditions, the temperature differences produced by the molten fuel deposited on the tray and the presence of the central chimney have the effect of setting up a natural circulation of liquid metal and consequently of cooling the fuel.

Abstract: Disclosed is a tubular housing having a threaded-base lamp bulb at one end and a "penlite" battery within the housing with its positive terminal stud separated from the bulb's positive terminal by a helical compression spring. The spring coils receive the lamp base and the spring is bottomed and centered in an annular retainer disc encircling the positive terminal stud of the battery. A conductive strap engages the endmost coil of the spring and extends the length of the battery to its base providing electrical continuity from the battery negative terminal to the bulbs threaded base. A push button, accessible at the end of the housing, moves the battery so that its positive terminal engages the positive terminal of the bulb.

Abstract: The primary coolant fluid is circulated within at least one primary loop between a steam generator and a pressure vessel. Within the steam generator, the primary fluid flows through a tube bundle and exchanges heat with a secondary fluid which is admitted in the form of water and discharged in the form of steam. After expansion within turbines and recovery in a condenser, the steam is then returned into the generator. The primary fluid circulating pumps are each driven by a turbine which is fed with steam taken directly from the steam generator or from the main outlet duct of the generator. The essential objective of the invention is to dispense with the use of an electric motor for driving each primary fluid circulating pump.

Abstract: The shade assembly for use in a lighting fixture is characterized by a knockdown construction so that it may be easily disassembled for purpose of storage or transport. The shade assembly is in the general form of a regular polyhedron and includes a set of at least three flat trapezoidal windows arranged in a closed figure with their short sides on top and their long sides on the bottom. A base member is centrally disposed in the region above the windows. There are also a set of at least three ribs, each rib extending along the juncture of two of the windows and having its upper end removably secured to the base member. Each window is removably secured to the two adjacent ribs.

Abstract: A water-cooled nuclear reactor is provided with a passive emergency shutdown and core cooling capability by providing it with emergency fuel element dispersal means operable from internal energy contained within the reactor pressure vessel for dispersing the core fuel content into an adjacent heat sink. In a preferred embodiment, the reactor is provided with especially designed fuel elements and fuel element guides to permit passive emergency core dispersal. The reactor shutdown mechanism also facilitates reactor refueling and permits selective on-line refueling during normal reactor operation.

Abstract: An altar includes a plurality of candle holders for candles formed from glass containers having wax and a wick therein. The candle is placed on a base which is relatively wide to provide stability. A cover is placed over the candle which partially covers the top opening of the candle. The cover is formed from a ring having a chimney extending upward from the inner diameter of the ring and a conical flange extending downward and outward from the outer diameter of the ring. The chimney has a plurality of holes spaced around its base. A pair of holding rods connect the cover to the base so that the candle is held beween the cover and base to form a semi-rigid stable assembly.The cover, which may be used separately from the base, functions to prevent air currents over the top of the candle from causing the flame to flicker and smoke the inside of the glass container. The cover also keeps heat contained in the candle to melt the wax evenly across its surface.

The assemblies each comprise a stack of spaced sacrificial plates mounted on a graphite column which collectively support the core.

Abstract: An electromagnetic filter of the type provided with a magnetizable packing and placed in the water circuit of a nuclear reactor is cleaned by a method which first consists in isolating the filter from the circuit, then subjecting it to a series of washing and draining-off cycles. The washing operation consists in withdrawing a fraction of water from the circuit and introducing it substantially at the temperature and pressure of withdrawal and under such conditions as to impart turbulent flow to the water within the packing. The draining-off operation consists in discharging the wash water contained in the filter.

Abstract: A home entertainment system and lighting cabinet simulates the sound and lighting effects of a discotheque. Light rays from a bank of differently colored lights are directed both to a mirrored rotating globe and to a rear reflecting panel behind the globe. A plurality of reflecting part-spherical domes and pyramidal-like projections are arranged on the rear panel and are configurated to reflect at least some of the impinging light rays back to the globe for subsequent reflection therefrom. The light rays reflected off the globe, domes and projections are projected about the room in which the system is located in a very dense pattern of reflected differently colored images. A stereo music system is mounted on the cabinet to combine a discotheque sound effect with the above-described lighting effect.
