A liquid rocket engine assembly comprising a thrust chamber, a nozzle, and a joint structure. The joint structure attaches the thrust chamber and the nozzle and comprises at least one seal element and an attachment ring interposed between the thrust chamber and the nozzle. Fasteners extend between the nozzle and the thrust chamber through the at least one seal element and the attachment ring. Materials of the thrust chamber and of the nozzle comprise different coefficients of thermal expansion. A method of forming a liquid rocket engine assembly is also disclosed.

A table may include a table top that is capable of being folded-in-half. In particular, the table top may include first and second portions that are capable of being moved being moved between a folded position in which the first portion is disposed proximate the second portion and an unfolded position in which the first portion and the second portion are generally aligned in the same plane. The table may also include first and second legs that are movable between an extended position and a collapsed position relative to the table top. In addition, the table may include a handle that facilitates carrying of the table. The handle may include a gripping portion that is sized and configured to be gripped by a user and the handle may be attached to the table top. The table may further include a handle retention assembly that secures the handle in a fixed position.

Handle for a portable table

A table may include a table top with a first portion that is movable relative to a second portion between a folded position and an unfolded position. The table may also include a retainer that is sized and configured to retain the table in a folded position so that the table does not unintentionally unfold when the folded table is being carried, transported and/or stored. To help retain the table in a folded position, the retainer may include a first end that is connected to the first portion of the table top and a second end that is connected to the second portion of the table top. In particular, the retainer may be connected to portions of the table such as the lower portion of the table top, the frame, one or more connecting rods or support members, and the like.

A chair including a backrest and a chair seat is disclosed. The back rest and the chair seat are preferably constructed from blow-molded plastic and an opening or hole may be disposed through a portion of the chair. The opening is preferably formed in the backrest and the opening may extend completely through the backrest. Advantageously, the opening may form at least a portion of a handle and the opening may be formed during the blow-molding process. The chair may also include a frame and one or more legs that support the chair seat and backrest above a surface such as the floor or ground. In addition, the chair may include a first groove formed in the lower portion of the chair seat and a second groove formed in the lower portion of the chair seat, and a first crossbar may be at least partially disposed within the first groove and a second crossbar may be at least partially disposed within the second groove. The crossbars and/or grooves may be sized and configured to increase the strength and/or rigidity of the chair seat.

Blow molded plastic structures are provided for use in various structures such as, but not limited to, tables, chairs, walls, backboards, storage bins, sports equipment and the like. The blow molded plastic structure has a first surface and a second surface extending between a first end and a second end and forming a chamber there between. A plurality of depressions is formed on the second surface and extends into the chamber. The depressions are usually unitary structures formed by a depression wall. Generally, the steeper the depression wall, the more strength is provided to the structure. In addition, where the plurality of depressions has a low profile and a greater density, increased strength is provided to the structure. The depressions may or may not be joined to the first surface.

An inflator is provided that can reduce the occurrence of virtual and masked leaks in inflator testing. The inflator may have an outer wall surrounding a main internal compartment containing compressed inflation gases. Additionally, the inflator may have a pyrotechnic assembly containing a generant, or pyrotechnic material, and an initiator configured to ignite the pyrotechnic material upon receipt of an electric signal from a vehicle's electrical system. The initiator may be separated from the pyrotechnic material, and from the compressed gases, by a pressure dome that effectively creates a cavity around the initiator. The initiator may be accessible to outside contact through an opening in the outer wall. An insert may be positioned around the initiator to control flows of gas leaving the cavity through the opening. Thus, during testing, residual gases within the cavity are able to escape the inflator within a predictable time period, so that the inflator can reliably be checked for gases exiting the main internal compartment. The insert may have a porous design so that gases escape from the cavity at a controlled rate during testing, but are unable to escape in any destructive manner during ignition of the pyrotechnic material.
