A gas regulator is of a modular construction, having a base providing coupling to a gas supply system and a body in which the pressure regulation elements are located. The base and body form a plug and socket type connection, the body being removable from the base, for repair or replacement without the base being disconnected from the gas supply. Inlet and outlet ports in the base align with corresponding inlet and outlet chambers in the body to provide a gas flow path through the regulator with the base and body connected.

The LED tube for a lighting fixture has a transparent peripheral portion, internally disposed grooves for receiving an LED array board opposite the transparent portion and externally disposed longitudinally extending slots to slidably receive connectors for the mounting of the fixture. Multiple tubes can be grouped together in arrays of two or more without requiring different fixture enclosures.

An air evacuation system is used for lining a container with a flexible liner. The air evacuation system includes a platform for supporting the container in a formed state, the container including the liner in an unseated position within the cavity. The platform includes a base and a floor extending substantially parallel and spaced apart from the base such that a first air gap is formed between said base and said floor. The floor includes at least one opening therethrough and at least one spacer tab extending therefrom. The vacuum assembly is coupled to the platform and includes a pump in airflow communication with at least one inlet positioned in said base, said vacuum assembly is configured to draw air from the cavity such that the liner is positioned substantially adjacent to the interior surface of the container in a seated position.

The invention involves a two-piece seat for a passenger-carrying vehicle with the seat being capable of complying with the federal requirements with reduced complexity. A steel plate is rigidly attached to the rotating seat back. The steel plate will prevent the seat back from rotating during normal use. If the bus were in a collision, a belted occupant would apply load to the rotating seat back through the seat belts. The steel plate would deform, allowing the rotating seat back to come forward. The fixed portion of the seat back remains in position to act as a passive restraint for any passengers seated behind this particular seat. Utilizing deformable steel plates to retain and control the operation of a rotating seat back equipped with 3-point restraints is a unique aspect to this invention. The plates will retain the rotating seat back in normal use to prevent vandalism to the seat belts, and can be easily removed so the seat back can be rotated forward for servicing the seat belts and upholstery covers.

The caster leg assembly has a slidable collar mounted on a shank that is threaded onto a stud fixed within a hollow table leg. A resiliently deformable ring is positioned between a shoulder on the shank and an inwardly turned end of the leg. A locking nut is threaded onto a threaded portion of the collar to abut the inwardly turned end of the leg. After the shank has been adjusted along the length of the stud, the locking nut is threaded against the end of the leg to cause the collar to be drawn in a direction out of the leg thereby compressively deforming the ring to frictionally engage the collar and leg. This, in turn, locks the shank against rotation relative to the leg.

A paste-the-wall wallcovering has a deep emboss paper ply (10a) adhered to a flat plastics ply (16) having perforations (22). The ply (16) can restrain the ply (10a) against any significant expansion in the course of hanging and paste drying. The perforations (22) are regulated on the one hand so that weight loss from the hanging paste is not so excessive that the paper ply becomes softened and, on the other hand, so low that tacking of the wallcovering to the surface on which it is to be adhered is not unduly delayed.In making the wallcovering the paper ply is moistened and embossed and allowed to dry just below ambient humidity prior to laminating it to the plastics ply. The wallcovering may be decorated in the course of manufacture or after hanging.

The housing of a panel fastener is provided with pockets along the upper edge of the elongated recess that receives a hook assembly or a pin assembly and pairs of locking elements are mounted in selected pairs of oppositely disposed pockets to engage adapters used in the foamed-in-place molding of a wall panel.
摘要:
An air evacuation system is used for lining a container with a flexible liner. The container has a plurality of walls defining a cavity with an open top, and each wall has an interior surface and an exterior surface. The air evacuation system includes a platform for supporting the container in a formed state, wherein the container has the liner in an unseated position within the cavity. A vacuum assembly is coupled to the platform. The vacuum assembly includes a pump in airflow communication with at least one inlet positioned adjacent to the exterior surface of a first container wall. The vacuum assembly is configured to draw air using the at least one inlet from the cavity through the first container wall such that the liner is positioned substantially adjacent to the interior surface of the container in a seated position.
