    Abstract: A machine for the manufacture of relatively thin sheetlike forms from a plastic material. A pair of belts is passed between a pair of mold members while having a charge of plastic material located between the belts to produce a desired form. The molds are brought together with the material and the belts located therebetween, at least one of the belts being employed to carry the material to, and away from, the mold members.

    Abstract: A CONTROLLED DEFLECTION ROLL HAS A NON-ROTATIVE SHAFT AND A SUPERIMPOSED ROLL SHELL WITH RADIAL SPACE BETWEEN THE TWO. END AND AXIALLY EXTENDING SEALS ARE CONNECTED TO THE SHAFT AND BEAR AGAINST THE INSIDE OF THE ROLL SHELL TO DIVIDE THE SPACE INTO TWO COMPARTMENTS, INTO ONE OF WHICH LIQUID IS INTRODUCED UNDER PRESSURE SO THAT WHEN THE ROLL SHELL IS WORKING AGAINST A COUNTER ROLL UNDER PRESSURE, THE DEFLECTION OF THE ROLL SHELL IS CONTROLLED BY THE PRESSURE ON THE LIQUID WITH CONSEQUENT OPPOSITE BEAM DEFLECTION OF THE SHAFT. ONE OR MORE OF THESE SEALS, AND PREFERABLY ALL OF THEM, IS FORMED BY A PISTON WHICH RECIPROCATES IN A RECESS IN THE SHAFT TO AND FROM THE INSIDE OF THE ROLL, THIS PISTON HAVING AN OUTER SURFACE FACING THIS INSIDE AND IN WHICH A RECESS IS FORMED TO FORM A HYDROSTATIC BEARING PAD COOPERATING WITH THE INSIDE OF THE ROLL, THIS INSIDE FORMING WHAT IS IN EFFECT A HYDROSTATIC BEARING RUNNER. THERE IS A FLUID CONNECTION BETWEEN THIS RECESS AND THE BACK OF THE PISTON AND A SOURCE OF FLUID UNDER PRESSURE IS CONNECTED TO THE RECESS THROUGH A FLOW RESTRICTOR SO THAT THE PISTON FORMS A SEAL ACTING LIKE A HYDROSTATIC BEARING. THE SOURCE OF SEALING PRESSURE MAY BE SEPARATE FROM THAT SUPPLYING THE ROLL DEFLECTION PRESSURE, EITHER IN THE SENSE OF BEING LITERALLY A SEPARATE SOURCE OR A SOURCE WORKING THROUGH A PRESSURE CONTROLLING SYSTEM, WHEREBY THE SEALING PRESSURE MAY BE VARIED INDEPENDENTLY OF THE ROLL DEFLECTION CONTROLLING PRESSURE.

    Abstract: When employed for driving fasteners or the like the tool has a muzzle end yieldably engageable with the work and a hinged housing carrying an element for striking the charge. A barrel breech end receives the charge when the housing is open and holds the charge for ignition when the housing is closed. Safety mechanisms controlled by a hand grip releasably locks the housing in operative position relative to the barrel and prevents firing of the charge unless the muzzle end is first thrust against the work by means of the grip.

    Abstract: An explosively actuated device for driving pins and studs, for instance, by using only one hand. Compact and simple in structure, the tool preferably employs an impact-ignitable primerless charge for generating gas pressure, a simple means for advancing successive charges from a supply source on the tool into firing position, and safety features preventing premature ignition. The loaded tool may be manually pushed against the locality of a workpiece which is to receive a fastener in order to initiate the explosion resulting in the fastener driving.
