Abstract: Apparatus is described for welding of thermoplastic parts and the like where the heat to melt the surface or surfaces to be joined is produced by friction during high frequency rubbing. The parts are adapted to be placed on a platen which enables the mating surfaces of the parts to be brought into clamping engagement in a welding head. The welding head includes a seismic mass. Stiff flexural members support a plate, against which the parts are clamped with respect to the seismic mass, and which provides for relative vibratory motion of the mating surfaces to be joined. A hydroacoustic driver is coupled to the plate and causes the plate to execute linear vibratory motion at a high frequency, where the stiffness of the flexural members is resonant with the mass of the vibrated portions of the head. Due to the stiffness of the flexural member and the high frequency of vibration, the relative displacement of the mating surfaces to be joined during vibration can be extremely minute.

Abstract: A self-contained dry wall taper has a hollow elongated body for holding mastic and supports a roll of tape with tape feeding means to deliver the tape to tape applying wheels that in turn apply it to cover a joint between two wall board sections.A piston is slidably mounted in the hollow body and is automatically moved by a mechanism actuated by the rotating wheels, as they are moved over the wall board surface, to force a layer of mastic onto the tape just prior to it being applied to the surface. Novel tape feeding and tape cutting means are actuated by a single sleeve which is moved forwardly on the hollow body to initially feed the tape into engagement with the tape applying wheels and is moved rearwardly to actuate the tape-cutting mechanism for cutting the tape.

Abstract: A method for manufacturing large disposable specialty drapes, particularly surgical drapes such as cystoscopy sheets and lithotomy sheets. Two strips of various stock material are automatically drawn to length from separate supplies, processed, and mated in the required configuration. The processing includes making of one or more fenestrations and, for those drapes requiring it, attachment of a filter. The material is then cut to length to provide the finished sheet. The work stations, at which the fenestrations are made, the filter attached, and the sheet cut, are spaced to permit these operations to be performed simultaneously on different sheets in a line. A control unit synchronizes and controls these operations. The finished sheet is provided with an improved filter which is attached to the sheet body by a heat sealing process, thus avoiding the separation of the filter due to excessive exposure to fluid in the course of a surgical procedure.

Abstract: The present invention constitutes a vacuum press for mounting and laminating graphic art objects such as photographs and the like. The press utilizes two pliable airtight membranes, a first membrane attached to and supported by a base frame and a second membrane positioned over the base frame, arranged to form an airtight chamber containing the workpiece. The second membrane is specifically chosen so as to have a contour-defining capability. Thus when the chamber is evacuated, exterior atmospheric pressure will collapse the chamber and compress the workpiece between the two membranes, and at the same time, the second membranes will image the upper surface contour of the workpiece so as to reveal any undesirable surface irregularities such as wrinkles or bubbles which might exist in the workpiece. This indication gives the operator an opportunity to remove the irregularities before mounting or laminating occurs.
