Abstract: A filter element is fitted into a filter can and a mass of hot-melt adhesive between the filter element and the can is thermally activated and allowed to cure to hold this filter element in place. A bead of hot-melt adhesive is applied to the rim of the can and the edge of a cover is applied over this bead which may be heated to its softening range. Thereafter the rim of the can is bent over the edge of the cover and this bent-over rim is heated to the melting point of the hot-melt adhesive so as to secure the two together once the hot-melt adhesive has cured.

Abstract: An electromagnetically actuated fuel injection valve includes a coaxial assembly of a connection tube, a bushing, a housing extension and a nozzle body. All seals between adjacent faces and edges of these elements are age-resistant metal-to-metal seals. The seal between the housing extension and the nozzle body is formed by pressing the overlapping end of the housing extension over annular edges on the nozzle body. The remaining seals are welds or solder-joints.

Abstract: The glass panel of a windshield is installed in an opening of the sheet metal car body by first placing on the edge of the sheet metal about the opening an elongated sealing strip of hook-shaped cross section and laminar structure, a core layer of metal being enveloped between two surface layers of elastomeric material. The sheet metal edge is received in the groove of a channel portion of the sealing strip, and a plate portion projects at right angles from the channel portion forward and outward of the opening, thereby permitting the glass panel to be placed in abutting engagement with the channel portion. The part of the plate portion projecting forward beyond the glass panel is enveloped in a loop-shaped rubber tube and folded over on the glass panel by inflating the tube. The folded-over strip firmly holds the glass panel under the pressure of the metal core.

The inner race member has a distal flange registering with the outer race member distal end and a tubular proximal section projecting through the end wall and base plate openings and having its end upset into engagement with the rear borders of the base plate opening.

Abstract: A double acting fluid pressure operated linear motor has an extruded cylinder member with a head endwall and mounting tang formed integrally thereon and has an annular step formed in the interior chamber at the rod end. A piston within the cylinder member is connected to a rod which extends through an end cap fitted against the annular step, the ends of the cylinder member being deformed inwardly to retain the end cap, rod and piston in place. This construction enables such devices to be manufactured extremely economically so that it is practical to discard and replace the actuator, if necessary, rather than performing repairs.

The method includes forming bottles from the same basic mold using different neck inserts with the nonaerosol bottle being formed with a continuous thread portion and both bottles including a transfer bead. A standard decorative overlay is formed. A resilient adapter ring is formed and permits the assembly of the overlay to the nonaerosol container in cooperation with the transfer bead. A valve retainer cap cooperates with internal ribs formed as part of the overlay to secure the overlay in the aerosol application.

Abstract: A glass container is molded with a recessed outlet end having a sharp outer edge and an enlarged lip. The outside surfaces of the lip of the container from a point adjacent the recessed opening are straight in part and convexly shaped in another part and terminate in a portion of reduced diameter at the neck of the container. A closure assembly centrally housing an aerosol "or pump-type" valve is formed with a depending flange, an annular stepped portion adjoining the central housing, and a concave surface portion connecting the stepped portion and the depending flange. A liquid elastomeric resin lining is flowed onto the concave surface and depending flange portions and cured to form a resilient liner. The closure assembly is then mounted upon the recessed open end of the glass container forming an inwardly diverging channel between the recessed outlet and enlarged lip of the container on the one hand and the stepped and concave portions of the closure assembly on the other hand.

Abstract: A method for manufacturing an oil seal element from polytetrafluoroethylene and the like. A tubular billet of polytetrafluoroethylene or the like is provided with an outer cylindrical surface of the desired diameter and an inner cylindrical surface approximating but slightly smaller than the desired diameter, and an end wall is faced off perpendicular to the cylindrical surfaces. A series of washers of a desired thickness is then sliced from the billet. The flat washer is then first assembled with a metal case and then a desired hydrodynamic shape, such as a spiral groove, is coined in. Preferably, the inner pierce is completed at this time. Each washer may then be formed under pressure to permanently deform the radially inner portion thereof to a frustoconical shape. The assembled seal may be held on a shaft-size mandrel during application of a coating to the metal case.
