Abstract: A system is disclosed for laminating surfacing materials, such as high and low pressure laminates, paper, wood veneers, metal foils and the like, to core material, such as plywood, particle board, flake board, hard board, rigid plastic foams and the like.The disclosure includes a machine for laminating, particularly utilizing high viscosity, hot melt adhesives within the ambient conditions of a factory. A sandwich is formed at ambient temperature with the adhesive between the laminate and core either as sheet material or precoated on the laminate or the core. The method employs a progressive heating of the adhesive and adjacent parts of the sandwich from ambient temperature through tackiness to an activating temperature followed immediately by a physical migration of the adhesive to wet out adjacent surfaces followed by a cooling of the sandwich to a mechanical bonding adhesive temperature.

Abstract: A collapsible container having two channel-like members which mate with one another to form an enclosure and two U-shaped brackets having inwardly facing grooves for receiving the edges of the channel-like members to secure them together. A method for forming the channel-like members from sheet metal or the like and the U-shaped members from elongated bars.

Abstract: A vacuum control system is disclosed consisting of a pedal actuated valve connected between a source of air under pressure and a Venturi tube where the valve and the Venturi tube are enclosed within a base and a treadle member pivotally mounted on the base for actuating the valve. The Venturi tube has a port in which a vacuum is created upon actuation of the valve to its open position. Air ejected from the Venturi may be noiselessly diffused by porous filler material disposed adjacent the output side of the Venturi. Further, the ejected air is directed away from the foot and leg of the operator by enlarging the clearance between the forward edges of the treadle member and base while decreasing the clearance between the rear edges thereof when the treadle member is depressed to actuate the system.

Abstract: Air flow control system comprising a pump having an air pressure outlet and a vacuum outlet; an air utilization device such as a desolderer; and a multi-position switch having first and second input ports respectively connected to the air pressure and vacuum outlets of the pump, the switch being positionable in a number of different positions whereby either one of the pump outlets can be selectively connected to the desolderer and the other vented to the atmosphere to prevent loading of the pump. In a neutral mode of operation, the desolderer is disconnected from the pump and both pump outlets are vented to the atmosphere to again prevent loading thereof. The switch also includes means for continuously varying the amount of air pressure applied to the desolderer.

Abstract: A solder removal device has air under pressure supplied thereto. The device has a hollow handle in which is disposed a Venturi structure for creating a vacuum where the vacuum is applied through a solder collection chamber also disposed in the handle and a solder extraction tube in communication with the solder collection chamber and extending outside of the handle. The air discharged from the Venturi structure is directed around the solder collection chamber and out an opening in the handle whereby heat is removed from the solder collection chamber, the heat having been generated by hot air and solder sucked into the chamber. Hence, the device may be used continuously for solder extraction without discomfort to the operator's hand.

Abstract: A desoldering device is disclosed which can be connected to a plurality of different pencil type soldering irons having a removable soldering tip. The device comprises a head member with an adaptor which can be secured to the soldering iron after the soldering tip has been removed. The head member has a through passage in which is positioned a hollow tube and copper tip. A base member is secured to the hollow tube and supports a glass container for receiving softened solder. A source of suction is connected to the base member for drawing the softened solder through the hollow tip and tube and depositing it in the glass container.

Abstract: A fushed eyeletting machine which constitutes an improvement over the structure disclosed by U.S. Pat. No. 3,739,141, the improvement features being in the upper setting tool mount structure.The upper arm of the C-shaped frame terminates in a pair of spaced apart tool support fingers, and a double stop toggle mechanism is mounted between the fingers, joined to a mandrel portion of the upper tool at a location thereon between the fingers.The electrical connection to the upper tool is adjacent the tool top and above the fingers.
