Abstract: WELL TYPE REFRIGERATED CASE WITH DEFROST AIR INTAKE AND COLLIDING BAND AIR DEFROST                   ABSTRACT OF THE DISCLOSURE    A well type open top refrigerated display case has a primary air conduit extending around the cabinet and main fans for circulating air through the primary conduit and across the open top of the cabinet in the form of an air curtain.  A column extends upwardly from and above the well type region; defrost fans are located in a defrost conduit in the column. Defrost control means are provided for energiz-ing the defrost fans at the start of a defrost cycle to draw ambient air from above the refrigerated display case into the upper portion of the defrost conduit at a higher pressure than the air pressure in the region of the open top; a portion of the higher pressure ambient air is directed out of the defrost conduit to collide with the air curtain flowing across the open top, the flow of the air curtain being thereby reversed and caused to flow over the top of and outside the display case.  A further portion of amibient air is drawn downwardly by the main fans to flow through the primary conduit and assist in defrosting the coils.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to a two-part, improved composition comprising:  a first part comprising a solution of a chloro-sulfonated polyethylene in at least one polymerizable vinyl monomer; and a second part comprising an activator composition which is formed from the condensation reaction of butyraldehyde and aniline, and containing no more than about 50% by weight of a substituted dihydropyridine, wherein the improvement comprises enriching the content of N-phenyl-3,5, diethyl-2-propyl-1,2-dihydxopyridine (hereinafter DHP) to a concentration of at least about 70% by weight of said second part.  The other condensation products in the second part should not exceed 30% of the weight of the second part nor exceed 42% of the weight of the DHP.  This enrichment results in a novel purified form of the activator which can be obtained by a variety of isolation and separation techniques to reduce the slipperiness, oily texture, obnoxious color and odor of the prior art activators.

Abstract: ABSTRACT The disclosed device is a marine seismic source which produces a varying FM signal in the low end of the acoustic spectrum.  The seismic source uses stiff oscillating radiators to create a signal in the water.  These radiators are attached to devices acting as springs with a variable spring rate.  Variation of the spring rate as a function of the frequency permits the device to be tuned for maximum power output.

Abstract: ABSTRACT OF THE INVENTION       A closure assembly comprises two separable closure members which are pre-assembled in coaxially stacked relationship, with their top panels aligned in the same direc-tion.  The lower closure member of the stack assembly comprises locking elements which are engagable with cooperating locking elements on a container, thereby providing a child-resistant closure.  The upper closure is a simple snap cap, plug cap, or other closure which is not child-resistant.  The upper closure is removably attached to the lower child-resistant closure by an interference fit between resilient attachment members integrally formed as parts of the upper and lower closures.  The assembly can be separated, for use of the upper closure only for sealing the container, thereby providing a choice between a child-resistant and non child-resistant closure.

Abstract: CONTROLLED CURRENT SOLENOID DRIVER CIRCUIT     Abstract of the Disclosure A solenoid driver circuit for a solenoid-operated fluid dispenser in which a valve is operable to dispense a fluid under the control of the solenoid.  The driver circuit receives externally applied turn-on and turn-off signals and energizes the solenoid in response to these signals.  The driver circuit is responsive to a turn-on signal to couple a pull-in voltage across the solenoid to pull in a solenoid valve armature.  The driver circuit is also operable to sense the level of current in the solenoid.  When the solenoid current reaches a preset peak current level, the pull-in voltage is removed from the solenoid and replaced by a hold-in voltage.  When the hold-in voltage is applied to the solenoid, the driver circuit is operable to control the level of the hold-in voltage in order to maintain a preselected hold-in current in the solenoid.  The driver circuit controls the solenoid current so that it makes a gradual transition from the peak solenoid current level to a steady state hold-in current level.  The voltage applied to the solenoid to establish the steady state hold-in current is removed by the driver circuit in response to an externally applied turn-off signal.

Abstract: QUENCHED NYLON MULTILAYER CASINGS    Abstract of the Disclosure An exact fit tubular food casing for pressurized filling is provided that comprises  a  tubular polymeric laminate having an outer layer of crystallized and moisturized nylon and an interior moisture barrier layer.  In one advantageous mode, the nylon is heat crystallized from  a  substantially  amorphous  state and  simultaneously moisturized. Associated method and apparatus for making said casing are also provided. In use, the casing is stuffed to within its elastic limit so that radial deformation is uniform along the length of the tubular casing.  As the exposed nylon dries out, the casing shrinks, thus further elastically stretching tightly over the stuffed food roll contained therein.  This contraction on dryout yields,  in effect, an apparent increase in the elasticity of the casing.

Abstract: ABSTRACT OF THE DISCLOSURE     A parison is molded from a gob of molten glass by first increasing the volume of the interior of a cup-shaped main mold body by an extra volume. Then, the molten-glass gob is inserted through an upper opening into the interior of the main mold body.          A neck mold comprising a split neck ring is closed on the main mold body so that the neck  mold and the main mold body together define a mold cavity partly formed by the interior of the main mold body.  A plunger is inserted through the neck mold down into the gob in the mold cavity to displace molten glass and shape the gob into a parison.  The  extra volume of the interior of the main mold body is then decreased to zero at the latest until the time at which the parison  is finished, so that the molten glass rises in the mold cavity up to a level above the top of the main mold body.  Finally, the parison thus formed is demolded,  It is therefore, possible to put a relatively large gob in the main mold body without any possibility of it overflowing, and the mold cavity can be shaped more like the finished hollow glass article, so that the resultant parison can be blown into a higher-quality product.
