Abstract:
A method and apparatus for coating the interior edge of an open ended container with an adhesive strip or band. An open rim of a container abuts a flat surface on an adhesive applicator head. A flowable adhesive passes radially outwardly and thence axially, between the inner container rim surface and a part of the head, to deposit a band of adhesive, such as a hot melt adhesive, on the container inner surface. The flat surface of the head functions both to position the container relative to the head and to form a seal to thus permit adhesive coating up to the edge of the open container end.
Abstract:
Apparatus for removing liquid from or evenly distributing liquid over magnetically attractible articles by using centrifugal forces. The articles are fed to a non-magnetic rotating drum, a helical series of magnets being arranged inside the drum adjacent the inner surface thereof.
Abstract:
A positive displacement pump for metering liquid chemicals and applying such chemicals into grains such as seed being conveyed through a screw conveyor, the pump including a reciprocating rod operated by an eccentric cam on the screw conveyor shaft, the pump rod having a shoulder and a stop carried by the housing to limit the length of movement of the rod, the stop being a rotary cam having flat surfaces, of varied distances from the cam axis and controlled by a hand operated knob.
Abstract:
The device comprises a body member having a liquid reservoir therein, a manually operable pump in communication with the reservoir, and an applicator post mounted on the pump. A metered amount of liquid is applied to the inner surface of a portion of a tubular member by manually placing the tubular member portion over the applicator post and then pressing inwardly of the device.
Abstract:
Apparatus is disclosed for impregnating a wall or the like with damp-proofing fluid. The apparatus comprises a conduit through which the fluid passes and carrying a sealing element designed to seal against the wall automatically under the pressure of the damp-proof fluid. Generally the sealing element comprises a grommet which is deformed into sealing contact with the wall, the deformation being effected either by the direct action of the damp-proofing fluid on the grommet or through an intermediate member such as a piston in a cylinder carried on the conduit.
Abstract:
Apparatus for forming articles by making a base of stretchable fabric, holding the base in stretched condition at opposed ends, rotating the base and coating the base with a curable plastic material.

Abstract:
Plastic dispensing apparatus in which charges of plastic material are deposited in successive caps carried by a conveyor, the plastic material being metered and delivered by a blade which executes coordinated rotational and translational movement to controllably deposit the plastic charges in deeply recessed caps.
Abstract:
A method and apparatus for interior painting of a pipe, particularly of small diameter, is characterized by filling of a pipe with both ends open with paint, hanging the pipe vertical and passing a ball of a diameter smaller than the inside diameter of the pipe from the upper end of the pipe to fall down by its gravity through the pipe and strip off excessive paint so as to form a film of uniform thickness of paint of the inner surface of the pipe.
