Abstract: ABSTRACT            The Specification concerns a refuse disposal system in which a refuse compacting unit located adjacent a wall of a building has a refuse input accessible from inside the building and a refuse output accessible from outside the building for dischar-ging compacted refuse into a removable container.            In order to permit a high degree of freedom in the placement of the container the unit is mounted on wheels for mobility and is located in an aperture in the wall, the aperture being substantially wider than the unit.  The unit is disposed between a pair of sliding doors mounted for movement parallel to the wall, the doors being coupled to opposite sides of the unit by upwardly directed rollers on the doors engaging inverted channels along opposite sides of the unit.  This arrangement permits free movement of the unit in a horizontal plane within the dimensional limitations of the arrangement, while ensuring that substantially the full width of the aperture in the wall is occupied by the combination of the unit and doors.

Abstract: (40 189 b)  INVENTION:  AN INSULATED OUTER COATING OF WALLS OF                       BUILDING STRUCTURES                     ABSTRACT OF THE DISCLOSURE The insulated outer coating of walls of building structures includes a cured foamed insulation material applied in a flowable state and an outer plaster means.         Metal plates forming the moulding form for the injected foamed insulation material  are connected by means of threaded bolts with the wall  of the building structure, whereby a space is defined between the outer surface of said wall and the inner surface of each metal plate. A flowable insulation material containing urea-formaldehyd is injected into this space and cured therein. Each metal plate comprises protrusions and perforations. The perfora-tions extend through the protrusions as well as through the metal plate. The plaster material applied on the outer face of the metal plates penetrates in its flowable state the penetrations and when cured is anchored by means of the protrusions and the penetrations. This arrangement allows the application of a not adhering or not sticking, respectively, insulation material, whereby the plaster is not carried by the insulation material but rather by the building wall itself. Conclusively, the insulation material is not subject to any forces stemming from the gravity of the plaster.

Abstract: REGENERATION SYSTEM FOR A               HYDRAULIC INTENSIFIER UNIT              Abstract of the Disclosure A hydraulic intensifier for oil well fracturing and/or erosion drilling, having a pair of intensifier units including a pair of sequentially operated  reciprocating  ram  assemblies  powered by hydraulic  cylinder  motors  which  are  operated  to maintain a substantially uniform output fluid pres-sure from the intensifier unit.  Each cylinder motor is supplied from a main source of hydraulic fluid under high pressure which operates  on the working faces of the pistons of the cylinder motors.  Hyd-raulic  fluid  is also supplied  to  the  return  face side  of  each  piston  in  the  hydraulic  cylinder motor.  The return face side of the pistons have a smaller operative area than the working face sides and each can be connected to the main source of sup-ply of hydraulic fluid to the working faces so that as the pistons are driven to their extended posi-tions by application of hydraulic pressure  to the working face, the fluid on the return face side can be expelled from the cylinder motors and returned to the working face side  to either  reduce  the  fluid flow from the source while maintaining the same cyc-ling  rate  or maintaining  the  same  flow  from  the source  by  increasing  the  cycling  rate and  thus increasing  the  total  volume  flow.   An  adjustable pressure relief valve is provided to permit control of the pressure in the well  to a maximum desired limit by relieving pressure of the infeed fluid to the hydraulic cylinder motors.

The pin is driven firstly through the tag, secondly through the merchandise, thirdly through the merchandise again, fourthly through the tag again, and fifthly through the tag again, and thereupon the movable pin guiding and pin crimping member is moved again to crimp the pin.  A bottom tag in a stack is separated by feeding it toward the pinning zone in one machine cycle and the separated tag is positioned between the anvil and the plunger during the early part of the next machine cycle.  The tag feeding device for separating the bottom tag and the tag feeding device for positioning the separated tag at the pinning zone move relative to each other during the pinning cycle.  A cycle of machine operation can only be initiated when manually operable actuators disposed on opposite sides of the anvil and plunger are both actuated.

Granted: 1984-01-10
Abstract: Aluminum laminae are heat-sealed onto the inside of flat-bottomed plastic bags so that, by bending the lamina double after the bag has been cut open to remove part of its contents, the bag can be reclosed. The apparatus for sealing the laminae on can be incorporated in an existing bag-filling installation. An aluminum strip is supplied to a punching device from a supply roll. A punched-out aluminum lamina is placed upon the upper part of a conveyor lever. The lever is rotated through 180.degree. so that the aluminum lamina to be sealed on comes to be positioned between two layers of a web of plastic material fed by rollers. The ends of the lever are preheated by heating elements in order to accelerate the sealing-on operation. The aluminum lamina is heat-sealed onto the inside of the folded web in such a way that the longer edges of the lamina form an angle of about 45.degree. with the flat bottom of the bag. The rate of production of the existing filling installation can be maintained despite incorporation of the sealing-on apparatus.
