Abstract: Apparatus and a process for bonding a core member to a housing member, particularly, in instances in which the members do not mate in a contiguous fashion. The invention includes some manual and some semi-automatic functions, but is largely automated and computer controlled. A conveyor carries an assembly of an initially joined but unbonded core member and housing member along a series of discrete stations. After some preparatory steps in the process, an initial continuous bead of sealant is first applied on one side of the assembly to close off the space between the members and thereby form a cavity between them. The bead is cured, then the assembly is inverted and the cavity is filled with an anaerobic bonding material. A second continuous bead of sealant is then applied on the other side of the assembly to close off the remaining space between the members as well to isolate the bonding material within the cavity.

Abstract: Modular positive displacement apparatus for dispensing precise quantities of a fluid product including a dispensing unit and an actuator unit. A housing of the dispensing unit defines a reservoir, a chamber and closure valve. The reservoir is divided into a plurality of sub-reservoirs, which contains the product. The walls dividing the reservoir into a plurality of sub-reservoirs provide guide surfaces for self-alignment of a product piston in the reservoir. A deformable diaphragm isolates the reservoir from the mechanism which actuates the valve to prevent undesirable entry of the product. The dispensing unit is readily removable from the actuator unit and can be readily replaced with another dispensing unit. Different nozzle sizes can also be accommodated. The extent of the closure opening is adjustable in discrete increments.

Abstract: A material dispensing valve finding particular application in the robotic dispensing of sealants, adhesives, etc. in a desired pattern on a workpiece. The dispensing valve comprises a unique actuating arrangement wherein back to back pancake cylinders are moveably arranged within a housing and, depending upon how the cylinders are actuated, three or four dispense rate positions can be provided. The dispense rate positions of the valve are preferably coordinated with the rate of movement of the robotic system so that the dispense rate is appropriate for the rate of movement.

Abstract: A card for mounting and displaying snack foods and other products packaged in bags is provided, which has a matched pair of locking tabs defined therein. The tabs are forwardly deflected to receive the reversely folded end flange of the bag therebehind, and are then forced rearwardly through the plane of the card to position the upper corners of the bag therebehind. This will provide secure, two-point support for the product bag, while also permitting ready removal at the point of sale. Generally, a multiplicity of bags will be mounted on the card, arranged in rows and shingled columns thereon. In certain embodiments, the tabs are desirably formed with nibs on their upper edge to deform and thereby better grip the bag, as is most desirable when the bag is made of a flaccid material.

Abstract: In order to form a band of coating material around the shanks of a plurality of headed articles, an arrangement is provided for conveying each article along a conveying path with a predetermined orientation past a coating applicator. The articles are initially supplied by a feeding device which emits, via a transfer device, the articles with the desired orientation onto the conveying path. The transfer device receives the articles from the feed device, accelerating them to a predetermined speed and transfers them to the subsequent conveying path with a predetermined minimum distance between each article. The subsequently arranged conveying path is formed by a pair of relatively horizontal and generally parallel conveyer elements, which elements are supported in a spaced relationship with a drive arrangement being provided for moving one of the elements relative to the other in a direction along the conveying path.
