Abstract: An adhesive dispenser for metering very small quantities of viscious liquids (grease-like materials) or thick pastes (putty-like materials) and transferring the metered material as a hemispherical or conical dot to a substrate at a high rate of speed. This device can be used to place adhesives between the conductive lands of a printed circuit board to adhere "chip type" electronic components between the conductive lands of the board. The dispenser comprises an outer cylinder carried in a support housing for movement toward and away from the board, the outer cylinder carries an adhesive metering device which places a dot of adhesive on the board.

Abstract: A form of stamp in which a height/diameter ratio of a drop of glue can be achieved which is larger than one fifth, for providing drops of glue on printed circuit boards or components in assembling electrical chip components. A projection having a height between one-tenth and one-half the largest stamp end face dimension, and a cross section less than one-quarter the end face area, projects from the center of the end face. These stamps reduce the effect of machine stoppage on the shape and dimension of the drops of glue.

Abstract: Apparatus is provided for handling gasket-forming material. This material is usually supplied in tubular cartridge form and is dispensed to a screen with a porous pattern which shapes the material to the desired gasket-configuration. The material is spread on the screen and forced through to the other side where the gasket pattern is applied to an adjacent transfer surface of a transfer pad. This pad with the pattern on the transfer surface is moved to a mateable surface of a workpiece located on a support spaced from the screen. The gasket-forming material is then transferred to the mateable surface. The gasket-forming material is dispensed from the cartridge with the aid of a cartridge holder having an opening at one end to receive a spout of the cartridge and having a plunger at the other end with a plunger rod extending outwardly therefrom. A fluid-operated cylinder is aligned with the plunger rod and has a piston connected with the rod.

Preferably, the actuating means is pneumatic. Preferably, the die means is characterized by ease of convertibility of differing sizes, shapes and styles of work pieces.

Abstract: A plastic tubular member, open longitudinally along one side, is compartmented across its width to receive a plurality of media for supporting different bacteria cultures; and is equipped with an inoculating wire which extends axially along the tubular member through aligned intramural openings between the compartments. To prevent contamination between compartments, and maintain them in a sterile condition before introduction of bacteria cultures, the intramural openings are sealed with drops of wax in a two-step process. In a first step, the inoculating wire, which extends beyond the ends of the tubular member, serves to support the tubular member with the compartment openings directed downward over a vat of molten wax. A reciprocating comb having a plurality of prongs is mechanically moved from a lower position in which it is immersed in the molten wax, to an upper position, in which the prongs engage the compartment openings.

Abstract: Apparatus is provided for applying a bead of gasket-forming material to a mateable surface of a workpiece. The apparatus includes a source of gasket-forming material and a screen having a predetermined pattern conforming to the desired bead of the gasket-forming material. A spreader applies the gasket-forming material to one side of the screen and the gasket pattern is then formed on an adjacent transfer surface of a transfer pad on the opposite side of the screen. Means are provided for moving the pad with the pattern on the transfer surface and engaging it with the mateable surface of a workpiece mounted on a support spaced from the screen, thereby forming a bead of gasket-forming material on the mateable surface. The transfer surface is moved through an arc of 180.degree. when moving between the screen and the workpiece surface.

Abstract: A liquid pick-up, transfer and deposit system achieves controlled thickness, reproducible deposits of viscous liquid, such as epoxy, on a substrate, for subsequent attachment of microscopic size dies, by maintaining a layer of uniform, thickness of the viscous coating in a receptacle and moving an applicator stamp, back and forth between the receptacle and a substrate constituting the workpiece. The deposit area and thickness of coating on the tip of the applicator is kept uniform by a gravity actuated plunger yieldable rearwardly opposed only by its own weight. The plunger tip accommodates itself to the surface it contacts.

Abstract: A quantity of solder cream is contained in a rotatably supported receptacle. An elongated dispensing spindle is rotated slowly about its axis and introduced into the solder cream. Upon removal from the receptacle, a swirl of solder cream adheres to the end of the spindle and is transported on the spindle to the desired workpiece. The solder cream swirl is brought into contact with the workpiece thereby depositing a controlled amount of solder cream at the selected location. Means reposition the receptacle before reintroduction of the spindle into the solder cream.
