Abstract: MINIATURE LIGHTWEIGHT FISHING REEL         Abstract of the Disclosure The disclosure relates to an improvement in closed face type spinning reels, in particular the design and construction of such reels to provide for a high degree of miniaturization and lightness in weight, without sacrifice of operational features A reel is disclosed which includes a generally cylindrical reel housing containing the working mechanism. A central frame, of generally cylindrical form, mounts substantially all of the work-ing parts, and cylindrically shaped front and back.reel casings are removably mounted on the central frame to completely enclose the mechanism. The rear casing mounts a thumb lever for actu-ating the reel mechanism during casting. An offset, hypoid type gearing arrangement is provided for the winding handle, enabling the main drive gear to be offset within the reel housing, in order to accommodate the presence, in a convenient position, of an adjustable drag control element of conventional but advanta-geous form. The central housing member includes an arrangement of inwardly projecting ribs, which effectively close the space between the housing wall and the line spool, while maintaining the weight of the housing at a relative minimum. The reel also includes, among other features, improved lightweight, economical arrangements for mounting of a line pickup pin in the spinner head and for securing a mounting tang to the central housing mem-ber. With minor modifications, the reel can be adopted for mount-ing above or below the fishing rod.

Abstract: ABSTRACT OF THE DISCLOSURE         A method for liquefying natural gas comprises heat exchanging a pressurized natural gas with two independent coolant circuits.  The first coolant circuit pre-cools the compressed natural gas.  After the natural gas is pre-cooled in the first circuit, a major portion is liquefied in heat exchange with the coolant in the second circuit while the remaining minor portion is liquefied in heat exchange with the flash gas formed when the so liquefied natural gas is expanded.  Subsequent to the flash gas being heat exchanged with the divided minor fraction of natural gas, it is compressed and then at least partly liquefied in heat exchange with the coolants in the first and second circuits and subsequently expanded in the separator containing said flash gas.

Abstract: ABSTRACT     A method of quenching anode effect when producing aluminium by electrolytic reduction, characterized in that the anode, when anode effect has started, is placed in an inclined position, so that the wearing surface forms an angle of up to 20  with the horizontal.  This method is called anode rocking and has obvious advantages: 1)  The surface of the bath remains at the same level.  The bath will merely flow from the one end to the other.  This can be advantageous for mixing of low and high alumina concentration in the bath. 2)  The wearing face of the anode will be inclined, so that the gas and the gas film can more readily escape, 3)  It is not necessary to make the cathode shells higher  in order to contain the bath. 4)  The energy consumption is kept down because the thermal insulation efficiency of the crust is not impaired by its being mixed with molten bath and alumina. 5)  The loss of energy through molten bath flooding over the crust is avoided. 6)  There is no spilling of bath onto the floor.

Abstract: ABSTRACT OF THE DISCLOSURE A connector for high tensile load attachment to an elongated rod, such as a resin bonded, glass reinforced rod, includes a high strength, elongated, metal cylindrical retainer having an internal shoulder formed at one longitudinal end and a plurality of outer peripheral threads formed at the other longitudinal end for the threaded attachment of a hook or other load bearing device.  The connector further includes a plurality of metal collets or rings, whose inner peripheral profile configurations are that of a pair of truncated cones placed base-to-base, serially, longitudinally received within the retainer.  The slopes of the cones of the collets rec-eived within the retainer are independently, variably preselectable to achieve optimum results. The junctions or edges defining the intersections of the bases of the cones are rounded off to avoid excessive stresses being transmitted to the rod.  In mounting the connector onto an end of an elon-gated rod, the retainer is placed around the rod and a desired number of the collets, depending upon the tensile load anticipated, are serially placed within the retainer and abut against the shoulder of the retainer.  An elastomeric O-ring seal is positioned securely about the rod and beneath the underside of the retaining cylinder.  An organic potting compound, for example an epoxy resin, is poured into the space between the rod and the collets and is held therein by the O-ring seal.  After the potting compound has set, the O-ring seal is removed and a suitable load bearing device or attachment may he threaded onto the threaded end of the retainer.

Abstract: ABSTRACT OF THE DISCLOSURE    A load monitoring system for monitoring loads that are cyclically applied to a force carrying member is disclosed.  The load monitoring system comprises a transducer for sensing the loads exerted and a differential load monitoring circuit which receives the transducer signals, generates a normal load reference signal relating to previous load signals received and compares the normal load reference signal to the present load signal to determine when the present load exceeds the previous load by a predetermined amount for successive cycles of operation.  The differential load monitoring circuit also includes an inhibit circuit which, during initial start-up of the cyclical load serves to inhibit the operation of the differential load monitoring circuit until such time as the normal load reference signals can be established.    Furthermore, an absolute load monitoring circuit is provided which detects when the loads in the force carrying member have approached the capacity of the force carrying member or any predetermined maximum load.

Abstract: HIGH CONTINOUS CURRENT CAPACITY OIL EXPULSION FUSE     Abstract of the Disclosure An oil expulsion fuse has multiple rupture-resistant fuse wire arc bores for providing fault current protection in high voltage distribution circuits in the 25-35 KV range.  In preferred forms, the fuse has a Teflon core defining three discrete, small diameter cylindrical bores, each containing a respective fuse wire, whereby sufficient deionizing gas flow is generated upon fusing of the wires to effectively extinguish arcs formed in the bores, even in the face of high recovery voltage rates associated with distribution voltages above 15 XV.  The multiple bores communicate with common chambers at respective ends thereof which are vented to allow connective oil flow through the fuse during normal operation. One chamber has a larger effective vent area than the other and the chambers at opposite ends of the fuse intercommunicate so that upon sequential melting of the fuse wires which occurs during fault interruption, the greater resistance to gas expulsion at one end of the fuse than the other causes gas to be directed down through the bores to prevent arc restrike.
