Described is a keypad and its method of manufacture. In one embodiment, a keypad is provided that includes a substrate having a plurality of donut-shaped recesses located at each site of a button for inputting user information, a plurality of cushions each filled with an incompressible fluid (e.g., water), a flex circuit layer, a plurality of metal membranes and an over-molded thermoplastic elastomer layer. During the over-molding of the thermoplastic elastomer layer, the plurality of cushions filled with an incompressible fluid prevents collapse of the space between the flex circuit layer and the plurality of metal membranes. After the layers of the keypad are assembled, the incompressible fluid is removed which leaves a space between the flex circuit layer and the plurality of metal membranes.

Over-molded keypad and method of manufacture

A keeper and a latch secures a first member such as a door panel against a second member such as a corresponding frame. The keeper is adapted for attachment to the second member and engages the latch in a fastened position.

Latch

A latch secures a first member such as a door panel against a second member such as a corresponding frame. The latch comprises a housing for mounting in the first member, a pawl adapted for engaging a keeper in a latched position on the second member and latch actuating means for selectively moving the pawl into a position away from the keeper in order to allow the first member to be opened.

A fastener connects panel members in a flush position. The fastener includes a pair of connecting members which are snap-fit within apertures provided within each of the panel members for securing the panel members together. The fastener also disconnects the panel members when secured together. For this purpose, at least one of the connecting members is removable from the panel member aperture to disconnect the panel members. The fastener allows the panels to be assembled together and disassembled quickly and with little or no tooling.

Snap-in fastener for panels

Apparatus for effecting high temperature catalytic conversion treatment of exhaust gases flowing in a large volume exhaust path comprising a plurality of separate catalyst panel assemblies, and a panel support assembly arranged to be mounted within the exhaust path and to separately removably support each of the plurality of catalyst panel assemblies so that high temperature exhaust gases within the exhaust path will flow therethrough in operation and each panel assembly can be conveniently serviced by simple removal. The panel support assembly includes an outer ambient temperature peripheral frame structure, an inner high temperature peripheral frame structure mounted within the outer peripheral frame structure for temperature responsive expansion and contraction with respect thereto, and an expansible and contractible high temperature resistant peripheral seal assembly between the inner and outer peripheral frame structures for maintaining a flow preventing seal therebetween. Each catalyst panel assembly is supported by an arrangement which includes doors openable to permit the catalyst panel assemblies to be removed. Each panel assembly includes a guarded high temperature resistant peripheral seal assembly for insuring that the flow of high temperature exhaust gases within the exhaust path is solely through the catalyst passages thereof.
