Abstract: Work Surface Support System Abstract A modular laboratory furniture system includes free-standing tubular frame modules and free-standing table arranged about a room in a pre-planned configuration.  The system further includes mobile carts movable about the room.  The frame modules and tables each mount a horizontal work surface.  Pairs of spaced-apart common support means mount the work surfaces and also are used to construct the carts.  The common support means includes a hollow vertical leg, a bracket member and means for securing one portion of the leg to the bracket member.  The base portion of the bracket member has a perimeter which mates with that of the leg.  Detachably secured to the legs of the spaced-apart support means are  rails. The rails support at least one storage component on the frame module, table and carts.  The common support means allow for mounting of work surfaces to the frame modules and tables and the construction of carts using a minimum of parts and provide for versatility in making changes in the system.

Abstract: Abstract of the Disclosure The invention relates to an acetylene gas reactor, preferably for fueling a combustion engine of a motor vehicle.  In a sturdily constructed cylindrical housing of the reactor there is, in vertical coaxial alignment, a lower annular water supply container which contains at its center a sludge collecting receptacle that broadens upwardly funnel-fashion and surrounds a sieve basket that is filled by gravity from a calcium carbide supply container above the sieve basket.  Encircling the sieve basket there is an annular spray nozzle arrangement that is fed from the water supply container and sprays the sieve basket and the calcium carbide contained in it.  The filling opening for calcium carbide is in the upper surface and the sludge removal opening is in the lower surface of the cylindrical housing.  The  acetylene gas, withdraw from the reactor housing through a connecting nipple, after suitable mixing with combustion air, is conducted to the gas intake nipple of the combustion machine to be operated, or of a similar consumption device, for example a burner nozzle.

Abstract: ABSTRACT OF THE DISCLOSURE         A device is provided herein for stabilizing, with reference to surrounded terrain, a cable splice therein.  The device includes a stabilizer rail adapted to be positionable in a supporting position adjacent the splice enclosure.  A spacer base member is slidably positionable longitudinally on the stabilizer rail and is adaptable to support a cable component of a cable splice enclosure.  Strap means are adaptable to hold the cable splice enclosure in position against the stabilizer rail.  Thus, it now has been discovered that a cable joint may best be protected from damage by enclos-ing the cable splice within a cable splice enclosure and securing the cable splice enclosure and adjacent portions of cable in an immobile position in relation to each other and at least stable or substantially immobile in relation to the surrounding terrain or to extended portions of the cable.

Abstract: ABSTRACT OF THE DISCLOSURE A  hermetic  rafrigerant  compressor  having  an electric motor and compressor assembly in a hermetic shell is cooled by oil which is first cooled in an external cooler 18 and is then delivered through the shell to the top of the motor rotor 24 where most of it is flung rad-ially outwardly within the confined space provided by the cap 50 which channels the flow of most of the oil around the top of the stator 26 and then out to a multiplicity of holes 52 to flow down to the sump and provide further cooling of the motor  and compressor.  Part of the oil descends internally of the motor to the annular chamber 58 to provide oil cooling of the lower part of the motor, with this oil exiting through vent hole 62 also to the sump.  Suction gas with entrained oil and liquid refriger-ant therein is delivered to an oil separator 68 from which the suction gas passes by a confined path in pipe 66 to the suction plenum 64 and the separated oil drops from the separator to the sump.  By providing the oil coolin of the parts, the suction gas is not used for cooling purposes and accordingly increase  in  superheat is  substantially avoided in the passage of the suction gas through the shell to the suction plenum 64.
