Abstract: ABSTRACT OF THE DISCLOSURE         A grid system for supporting a plurality of individual panel members generally in the same plane.  A grid is formed of a plurality of structural beams or grid members which are disposed in intersecting relationship to each other in a pre-determined geometric relation.  More specficially, the grid system is adapted to be suspended from the superstructure of a building and includes a plurality of spaced, parallel grid members.  Each pair of such grid members are adapted on their opposite sides to support the marginal edge portions of ceiling panels while the adjacent sides of each pair of grid members are appropriately spaced and formed to receive an outlet portion of an air handling conduit for conveying conditioned air from a plenum-like structure disposed between the grid system and the overhead building superstructure into the room below the grid structure.  In this regard a pair of grid members is dis-posed only in a longitudinal  orientation over the room.  In this embodiment, single grid members are disposed transversely to the pairs of spaced, parallel grid members 80 as to provide support for the corresponding transverse edges of supported ceillng panels.  Bridging clip means are assembled to the pair of grid members to maintain them in spaced, parallel disposition with respect to each other.

Abstract: ELECTROCHROMIC DISPLAY APPARATUS          Abstract of the Disclosure The specification discloses an electrochromic display apparatus which comprises a container for an electro-chromic solution, a pair of electrodes, namely an indication electrode and a counter-electrode, disposed in the container, and an electric circuit for impressing a D.C. pulse across the electrodes and thereafter for short circuiting the electrodes together.  By means of the short circuiting, a color indicating substance formed on the indication electrode by the electrochemical reduction reaction or the electrochemical oxidation reaction is dissolved from the indication electrode into the solution so as to erase the indication.  The short-circuiting avoids the usual contamination of the indication electrode produced by the prior art method of erasing by means of impressing a pulse of inverse polarity across the electrodes.          A longer life for the apparatus can thus be achieved in com-parison with conventional apparatus since the contaminating substance on the indication electrodes of the prior art apparatus actively reduces the life thereof.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention is a resilient clip for connec-ting an electrical cable associated with medical equipment to a conventional male electrode.  The prior art includes snap-on terminals and terminals comprising a pair of pivotal plates movable to provide passage of an enlarged portion of the male electrode   Upon subsequent release, the plates tend to retain the clip on the male projection.   However, with prior systems, insulation of the clip conductor elements has not been provided, allowing possible electrical disturbances through inadvertent contact with the male electrode.  Further, the prior art clips may be inadvertently tilted, causing a cam action tending to force the clip off of the electrode.  The clip of the present invention solves these problems by providing a clip constructed of a dielectric resilient plastic material in a generally V or wishbone configuration in which the arms are integrally molded to each other at one end and diverge to a spaced relationship at the other ends.  Resilient wire loops are provided on each of the arms at points spaced from the one end and generally facing each other in a condition to overlap when the arms are biased by an external force towards each other.  The clip is provided with means preventing accidental contact with the male electrode when the clip is in position thereon, and with means preventing undesired tilting of the clip thereby minimi-zing unintentional disassembly of the clip from the electrode.

Abstract: VISCOUS OIL RECOVERY METHOD       (D#73,500-RCA-35-F) ABSTRACT OF THE DISCLOSURE         Viscous petroleum may be recovered from viscous petroleum-containing formations such as tar sand deposits in a process employing a cyclical injection-production program in which first steam is injected and fluids are produced without restriction until live steam production occurs at the production well, followed by steam injection with production throttled until the formation pressure at the production well rises to a value between about 60% to 95% of the steam injection pressure, after which fluid production is permitted without restriction and steam injection is reduced to 50% or less of the original injec-tion rate.  The process should be applied to a viscous petroleum formation in which adequate communication exist or in which a communication path is first established.          Optimum results are obtained if the pressurization and drawdown cycles are initiated shortly after the beginning of the steam injection program, and the benefits include substantially increased oil recovery efficiency at all values of steam pore volumes injected.

Abstract: Abstract of the Disclosure An arrangement including an automatic transfer switch, a bypass switch, and mutually cooperable pairs of contacts for electrically connecting the two switches. The entire transfer switch is movable as a unit toward and away from the bypass switch to engage and disengage, respectively, the cooperable pairs of contacts, disengagement of the contacts serving to isolate the transfer switch from the bypass switch and from the power sources and load. The transfer switch cannot be isolated from the bypass switch when the latter is open. The bypass switch can only be closed in a direction which connects the load to the same source of power to which the load is connected through the transfer switch. Each mutually cooperable pair of contacts engage each other solely by friction. There are at least three cooperable pairs of contacts, for connecting the transfer switch to a normal source of power, to an emergency source of power, and to a load, respectively. The two pairs of contacts for connecting the trans-fer switch to the sources engage before the pair of contacts for connecting the transfer switch to the load when the transfer switch is moved from a position in which all the cooperable pairs of contacts are disengaged toward a position of engagement.

Abstract: BE 19'022 MOLDED CASE FOR RETURNABLE BEVERAGE BOTTLES                           Abstract Of The Disclosure The disclosed case is of the type integrally molded from thermoplastic resin and rectangular, with a lattice floor.          The outer bottom side of the floor is so formed as to facili-tate nesting of the case on another. Four pillars extend vertically in two facing pairs from the floor, for separating bottles in the case sufficiently to prevent breakage in hand-ling. The pillars of a pair are separated by a slot so that bottles can be accepted together with a carrier, with a wall of the carrier being slid into the aligned slots of the pillar pairs. The improvements in the case include that the pillars are open on their facing sides; there are inner longitudinal reinforcement ribs spaced to both sides of their spines, mid-way between the spine and the edges; a short web of material fills the gap between the facing edges of the pillars in the slot on each side of the slot adjoining the floor; the pillars are anchored to the floor lattice by anchoring points which include at least points located on the outside of the pillars directly opposite the inner reinforcement ribs. These features stabilize the spacing between the pillars, so that they do not pull toward each other as a result of stresses developing after removal from the mold.

Abstract: ABSTRACT OF THE DISCLOSURE In order to prevent damage due to frost heaving of a refrigerated gas pipeline which traverses frost-susceptible soil resulting from horizontal ice lense formation beneath the pipeline, heat pipes are located in diame-trically opposed pairs, one on either side of the pipeline.  Frost bulbs are formed in the soil around each heat pipe adjacent to the pipeline, causing the horizontal ice lenses to be formed further below the pipeline. Heaving rate is reduced due to the lower temperature gradient in the vertical direction, a greater overburden above the horizontal ice lenses and a reduced water supply directly beneath the pipeline.  Also, lateral expansion of the frost bulbs provides opposing horizontal forces to counteract the upward force of the horizontal ice lenses.
