Abstract: ABSTRACT          The invention is directed generally to elec-trical connectors and, more particularly, to a connector for providing a plug-type interconnection between a solid wire conductor and a wire-wrap terminal post, such as on a panelboard.  At present, temporary connections of individual wire conductors to a terminal post are made by simply wrapping the stripped end of the wire conduc-tor around the terminal post.  This operation is ex-tremely time-consuming and labor-intensive.  Furthermore, the winding of the wire conductor around the terminal post seriously weakens the conductor and, therefore, the conductor must continually be cut back and re-stripped on succeeding operations, resulting in consider-able waste.  The connector of the present invention includes an elongated insulating housing having first and second openings respectively dimensioned to conform to the terminal post and the solid wire conductor.  The housing contains two spaced-apart electrical receptacles interconnected by a conductor or a circuit element, such as a diode, each receptacle having a pair of spaced-apart spring contacts with the pairs of contacts respec-tively disposed adjacent to the two openings in alignment therewith for receiving and electrically contacting the terminal post and the solid wire conductor.  The housing carries a strain relief member adjacent to the conductor opening for receiving the insulated portion of the con-ductor.

Abstract: ABSTRACT OF THE DISCLOSURE           A container is disclosed for receiving a stack of articles to be sequentially removed from a dispensing station of the container.  A stack positioning element in the container is movable fowardly in the container into engagement with an article stack to urge the forward-most article forwardly toward the dispensing station.  As articles are removed the stack positioning element normally moves fowardly by an amount equal to the thickness of each article that is removed.  However, means are provided for increasing the positioning element's movement in response to removal of the last article, whereby a sensing means can more readily detect such movement to thereby cause an indication of an empty container.

Abstract: A B S T R A C T       An underground storage reservoir for LNG or other fluids at cryogenic temperatures comprises an under-ground cavern 10, usually insulated, in which the cryogenic fluid is stored, an inner circulation system surrounding the cavern and comprising a plurality of passages in or adjacent the cavern wall or in the ground immediately surrounding the wall, and an outer circulation system comprising a plurality of ducts surrounding and spaced from the inner circulation system.  During operation of the reservoir to store a cryogenic fluid, a heat exchange medium is circulated through the passages of the inner circulation system so that the temperature of the cavern wall and the ground immediately surrounding the wall is maintained within a pre-determined temperature range higher than the temperature of the stored fluid, and so that water vapour which enters the passages from the surroundings is absorbed and removed by the heat exchange medium.          In addition, a heat exchange medium is also circulated through the ducts of the outer circulation system so that water in the ground surrounding the ducts is frozen to form a frozen zone in the ground spaced from and encircling the cavern and the inner circulation system.  This frozen zone halts the otherwise continuous drainage of water into the reservoir area from the surrounding ground both during construction of the cavern and the inner circulation system and during subsequent operation of the reservoir.  In addition, the operation of the inner and outer circulation systems serve to substantially reduce the rate at which water vapour migrates through the ground in the reservoir area towards the storage cavern.    The inner and outer circulation systems of the reservoir can also be used to perform other functions, such as the sealing of cracks in the ground within the reservoir region by distributing sealing substances under pressure, collecting and removing any stored product which may have leaked into the ground from the cavern, and perhaps also, by suitably adjusting the operating pressures, causing gas to diffuse outwards through the ground to the outer circulation system in counterflow to water vapour migrating inwards.

Abstract: METHOD AND APPARATUS FOR PUMPING FLUIDS FROM BORE HOLES    ROBERT L. CRAMER     ABSTRACT OF THE INVENTION   Well pumping method and apparatus by means of which the liquid level and, correspondingly, the hydrostatic pressure in a bore hole or well casing, is controlled by means of a vertically adjustable sump for receiving liquid from the bore hole or casing before it is pumped to the surface, the sump having therein a pump which is actuated by the liquid level in the sump so that liquid cannot rise in the bore hole or casing above the top or inlet of the sump, as the liquid enters the sump at this point and is pumped to the surface from the sump, the operation being such that the liquid level in the bore hole or casing is controlled by vertically positioning the sump so that the height of the column of liquid in the casing or bore hole above the point where liquid is coming from the formation can be maintained at a minimum with consequent increase in the differential hydro-static pressure between that in the well bore and that in the formation in the direction of the well bore, enabling the maxi-mum rate of liquid entry into the well bore. The sump prevents water from the lower portion of the formation from coming into direct contact with the pump and being pumped directly to the surface to exclude oil from being pumped to the surface.    Using the sump, the action of the water entering the casing or bore hole is such that the water will rise in the annulus between the outer sump wall and the inner wall of casing or bore hole and pass over the lip and into the sump without impeding the flow of oil from our of the upper portion of the formation, the oil also passing into the sump and also being pumped to the surface together with the water.
