Abstract: Disclosed is a high pressure flow line connection. The connection includes a tubular male member, a tubular female member and a seal ring positioned between the male and female members. The male and female members have mating frusto-conical tapered surfaces, with the angle of taper of the female member being less than that of the male member. The seal ring has inner and outer tapered surfaces having angles of taper equal to those of the male and female members, respectively. The seal ring includes a radially outwardly extending lip adjacent the maximum outside diameter thereof. The male member, female member, and seal ring are cooperatively figured such that the seal ring lip remains spaced apart from the female member but optimum sealing engagement is achieved.

Abstract: A method of reducing the porosity of a casting (e.g. aluminum or al alloy) by subjecting the casting at elevated temperature to isostatic compression comprising the following steps:
 (a) locating the casting (10) in a surrounding container (11) having at least one wall provided with at least one through-going channel (13),
 b) heating the container with the enclosed casting
 c) placing the heated container with the enclosed casting in a press chamber (20) of a fast-acting press, as for example a piston press,
 d) filling said press chamber with a liquid pressure medium at a lower temperature than that of the heated container and casting, and
 e) rapidly applying pressure to the liquid pressure medium. 
<??>Thus the liquid pressure medium is rapidly forced through the channels in the walls of the container and thereby heated up by extracting heat from the walls of the container.

Abstract: A night vision viewing system (13a or 13b) suitable for mounting on an observer's headgear (11) wherein light rays from a forward scene pass to the observer's eye (E) via a path comprising a forward looking objective lens (19), a first inclined reflector (23) which directs the rays upwardly onto the input face of a downward-looking image intensifier (25). Intensified rays from the image intensifier pass, in turn, via a fibre optic stub image rotator (27), a second inclined reflector (29), a relay lens arrangement (31) and third and fourth inclined reflectors (33) and (35), the fourth reflector directing the rays downwardly into an eyepiece (15) which is in the observer's forward line of sight. The eyepiece (15) incorporates an internal surface (39) having both light reflective and light transmissive properties which directs rays entering the eyepiece (15) from the intensifier (25) to the observer's eye. The fibre optic stub serves to effect rotation of the intensified image to present an intensified image of correct orientation to the observer. The configuration of the system allows the possibility of achieving an optimal position for the centre of gravity of the system in relation to the neck pivot position of the observer.

Abstract: A method and a device for detecting oscillations in the core of a boiling-water nuclear reactor (BWR) comprising a plurality of neutron detectors, wherein instability is detected based on oscillations in the output signals of the neutron detectors. For each one of a number of selected neutron detectors, oscillations in the output signals of the neutron detectors are detected. The oscillations are detected on the basis of an oscillation signal (SS) which indicates that an oscillation criterion is fulfilled. An alarm signal for remaining oscillations Ka is generated if the oscillation signal (SS) remains during one delay interval (T3). A first alarm signal (LR) is generated if the oscillation signal (SS) indicates that the oscillation criterion is fulfilled at least once, during each of a predetermined number of consecutive alarm intervals (T1). An alarm signal for intermittent oscillations (Ra) is generated by blocking the first alarm signal (LR) when the alarm signal for remaining oscillations (Ka) is present. (FIG.

Abstract: The heat in an electrical heating wire is transferred by way of radiation, or conduction, or convection. Especially in the case of highly rated elements operating in air, where the temperature of the environment is relatively cold, heat transfer by radiation is predominant. In order to achieve as low element temperature as possible at a given surface loading, it is desirable to raise the emissivity coefficient. The surface coating on an element of which the base material is an alloy containing 10-30 weight % Cr, 2-10 weight % Al, maximum 5 weight % of other alloying elements and balance Fe, according to the present invention consists of metal, metal alloy, metal compound or metal oxide with an emissivity coefficient which is higher than that of aluminium oxide. Different metals could be considered for the surface coating, most suited are nickel, cobalt, chromium and iron. In addition to the increase of the emissivity coefficient also other advantages are achieved, for example improved deformation stability at operating temperature.

Abstract: In an antenna system having an array of antenna elements (10, 10') and circuitry (111, 14) for controlling the phase of each element an arrangement (113) is provided for correcting the phase setting of each element as a function of the position of each element within the array expressed in polar co-ordinates. The phase correction is proportional to the sinusoid of the angular position of the element and proportional to an odd polynomial of radius having at least one term of third order or above. The resulting beam pattern includes low side-lobes in the lower hemisphere and gives rise to only limited and acceptable power loss on transmission. Furthermore, the implementation is rendered very simple, as the phase correction may be calculated element by element.
