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: An improved insulation system is used to insulate the roof of a metal building. The insulation system includes insulating boards which are suspended beneath roof panels by flexible sheets of material. The flexible sheets are attached to structural members, that is, to purlins beneath the roof panels. The flexible sheets have a width which is greater than the width of the insulating boards so that longitudinally extending edge portions of the sheets project outwardly from the edges of the insulating boards. The edge portions of the sheets are connected with the purlins at locations above the insulating boards so that the flexible sheets hang downwardly to suspend the insulating boards beneath the roof panels without compressing the insulating boards.

Abstract: A hand-held, manually-operated device for dispensing a viscous liquid in conjunction with a wiping action. Downward pressure on a handle causes expression of viscous material through one or more perforations or orifices in a flexible seal which is in abutting relationship with a surface to which the material is to be applied. As the device is slid across such surface the flexible seal provides both a sealing and a wiping action. When downward pressure is released, an expansion gap is created within the device, thereby relieving expression forces.

Abstract: An anti-drip caulking device is provided having a "floating" anti-kickback dog which engages the plunger shaft. When the forward motion of the shaft is stopped, the floating action permits recoil of the plunger and dog until a tension spring is sufficiently stretched to balance the recoil force, or until a mechanical stop is engaged. The floating feature is provided by a tension and compression spring acting in opposition.
