Abstract: Refrigeration Purging System Abstract A purge system for use in a refrigeration system utilizing more than one condenser, each of which operates at different pressures. The purge system includes a purge chamber having a cooling coil connected to the evaporator and adapted to condense refrigerant vapor.  The purge chamber is connected to a main purge refrigerant line which includes a pressure reducing device.  Either condenser in the refrigeration system is provided with a secondary purge refrigerant line connected to the main purge refrigerant line and having a one-way valve to prevent refrigerant flow from one condenser to another condenser.  A pump is mounted in the system to remove the non-condensibles from the purge system.  The pump is operatively connected to a pressure switch arranged between two sampling pressure lines, one of which is extending to the purge chamber and another one is extending to the main purge refrigerant line at a point ahead of the pressure reducing device.  The pump is actuated when the pressure differential between the purge chamber and the main purge refrigerant line drops below a preset amount.

Abstract: APPLICATION FOR LETTERS PATENT                       FOR    METHOD OF MAKING A THREE-DIMENSIONAL LAMINATE                ABSTRACT OF THE DISCLOSURE    A heat-sensitive, three-dimensional thermoplastic layer is laminated to a thermoplastic substrate by a specific fusion bonding process which produces a laminate having substantially no thermal distortion.  This process employs  cooling to protect the three-dimensional structure from thermal damage and balancing of the heat flow from the substrate to prevent warpage.  In the preferred process a grass-like sheet of low density polyethylene is fusion bonded to a rigid high density polyethylene sub-strate.

Abstract: TITLE:   POWDER-ACTUATED TOOL WITH POWER ADJUSTMENT          AND ANGLE-FIRE CONTROL     INVENTOR:   Jean Ollivier DOCKET NO.:   R-1191 ABSTRACT OF THE DISCLOSURE    An improved indirect-acting powder-actuated fastening tool is provided wherein the power level may be continuously varied and wherein the tool may be discharged only if the muzzle is pressed against the work surface, with the tool substantially perpendicular thereto.  A barrel and a barrel breech are adjustably screwed together and telescopically carried by a slide assembly which, in turn, is telescopically carried by the tool receiver.  The slide assembly and the barrel are operably connected for corotation, whereby rotation of the slide assembly produces a joint axial displacement, of the barrel and the slide assembly, relative to the barrel breech, to vary the initial volume.  The axial relation between the slide assembly and the barrel is thus preserved during power level adjustment and this constant relationship is utilized to effect angle-fire control by means of a firing mechanism operable solely when the slidably mounted barrel and barrel breech are urged to the battery position against the bias of a spring.

Abstract: APPARATUS FOR FORMING A CONTAINER                    ABSTRACT          A bucket shaped container having a rim opening smaller than the diameter of the sidewall thereof is in-jection molded from thermoplastic material using a die set including a molding core which collapses to allow axial removal of the molded container from the mold.  The molding core comprises a plurality of individual, wedge shaped outer core sections which collectively form a continuous molding surface and are slidably mounted on a tapered inner core to allow axial sliding movement of the outer core sections relative to the inner core.  Each of the outer core sections is also mounted for radial sliding movement on a mounting plate which circumscribes the molding core and is mounted for reciprocating axial move-ment relative to the inner core.  Reciprocation of the mounting plate produces simultaneous axial and radial move-ment of the outer core sections throughout their entire lengths between an expanded molding position and a collapsed container releasing position.  A plurality of rim molding segments mounted for radial sliding movement on the mount-ing plate automatically shift between molding and release positions in synchronism with the axial travel of the outer core sections.

Abstract: SELF-ACTUATING VARIABLE RATE      WATER PIPE BLEEDER               Abstract of the Disclosure The pipe bleeder includes a small holding tank and a sample tube, both of which are filled with water and exposed to the ambient atmospheric temperature.  The water in the sample tube freezes first when the ambient temperature is at freezing, which in turn causes a piston and then a push rod in the sample tube to move, the top of the push rod acting against a small cover plate in the holding tank, moving it away from a drain connection.  When the cover plate is so moved, water from the water supply pipe will flow at a relatively slow but steady rate through the drain connection to the environment, maintaining a flow of water through the supply pipe and thus preventing the water in the water supply pipe upstream of the pipe bleeder from freezing.  An exterior thaw tube is also attached to the drain connection in the holding tank.  When the ambient temperature increases to a few degrees above freezing, the ice in the thaw tube will thaw, resulting in a spray of water from the end of the thaw tube, which is directed into an interior thaw tube which is inside the sample tube, thawing the ice in the sample tube.          The thawing of the ice in the sample tube results in the piston and the push rod retracting and the cover plate moving back into place, closing off the drain opening.

Abstract: ABSTRACT A method and an apparatus for the production of stamp or photo album leaves with slip-in pockets for the stamps. Two trans-parent sheets in web form are linearly bonded to one another, and slip-in pockets are stamped out of the bonded sheet material to form double sheet pockets joined along a linear edge. The slip-in pockets are stamped out of the double sheet web by a stamping tool assembly in a predetermined arrangement corresponding to the pocket placement intended for the album leaf, and holds them firmly in this arrangement by a partial vacuum. In the meantime, an adhesive has been applied to the album leaf in the places provided for the slip-in pockets. The album leaf is then brought into contact with the slip-in pockets held fast by partial vacuum on the stamping tool so that the pockets are secured to the album leaf.
