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 as to isolate the bonding material within the cavity. The second bead of sealant is also cured after which the fully bonded assembly is removed and replaced with a fresh assembly to be operated upon.

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.

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.
