When the chair is folded for storage, the back and seat are rotated toward each other to a fully closed position.

Abstract: A covering for an expansion joint of a building is formed from an extruded thin vinyl strip having a relatively thick expanded plastic insulating strip secured to one side of the vinyl strip. A reinforcing strip of material may be bonded securely to the vinyl between the vinyl and foam insulating strip in a sandwiched configuration to provide dimensional stability for the assembly and particularly to resist shrinkage of the assembly in a longitudinal direction. The vinyl strip is wider than the foam insulating strip to define longitudinal marginal flanges extending along the length of the strip. Metal nailing strips are embedded in the longitudinal flanges to facilitate attachment of the flanges to the spaced building sections which define the expansion joint. The nailing strips are formed to define a weakened, longitudinally extending line to facilitate longitudinal bending of the flanges along the nailing strips directly at the construction site without the use of heavy bending equipment.

Abstract: An improved composite concrete and steel construction system for floor framing members using composite action open web steel joist and concrete slab construction, composite beams; unpunched corrugated decking and composite joists at columns only. All beams are composite and all joist ends are composite at the beams. Joists between the columns are standard open web joists. This composite system results in the columns having floor supporting members in both major directions that are composite with the poured in place concrete slab, thus providing superior bracing of the columns and direct duplication of the horizontal forces in the slab to the column through the supporting members. This design utilizes less composite joists, allows greater leeway in the spacing of the composite joist webbing and is economical. The floor slab will still act as a diaphram in both major directions due to the composite beams and the composite joists at the columns acting at right angles to one another.

Abstract: Moisture entrapped within roofing systems of the type wherein a layer of normally low-permeance, cellular plastic insulation board (e.g. foamed polystyrene) is employed in conjunction with at least one layer of moisture-bearing construction material (e.g. lightweight insulating vermiculite concrete) is made able to be vented from within the system by providing the board with a plurality of openings therethrough and further preventing the fluid construction material when placed upon the board from entering and filling the openings. Such prevention of filling of the openings may be accomplished by making the dimension of the openings such that the fluid construction material will not flow therein yet moisture will pass, or by covering the openings with a material (e.g. paper) which will prevent such filling, the material however being permeable by any moisture later entrapped within the roofing system.

Abstract: An electronic watch having a time counter for counting a time standard signal to develop a count representative of present time, a recurrent alarm time memory circuit for storing a recurrent alarm time, and a single alarm time memory circuit for storing a once-occurring alarm time. A setting circuit is operable for clearing the contents of the single alarm time memory circuit. A coincidence detecting circuit detects coincidence between the contents of the time counter and the contents of both memory circuits, and develops an output signal when coincidence is detected. Alarm time clearing circuitry responds to the output signal of the coincidence detecting circuit for enabling the setting circuit to clear the single alarm time memory after the once-occurring alarm time has occurred. An alarm circuit is responsive to the output signal of the coincidence detecting circuit for developing an alarm each time the contents of the time counter coincides with the contents of one of the memories.

Abstract: In a vehicle having an engine which derives power from a reaction of NaK and water in the presence of air, NaK hydroxide is a reaction product in the form of particulates suspended in an exhaust gas consisting principally of nitrogen with some water vapor. In order to release the exhaust as a harmless gas to the atmosphere and to retain the NaK hydroxide in the vehicle for removal during a fuel stop and subsequent reduction back to NaK metal, several stages of separation of the particulates from the gas are provided. A first stage, preferably based upon impingement of the NaK hydroxide particulates on a molten NaK hydroxide surface, separates a substantial portion of the particulates. A final stage of separation comprises filtration wherein two filters are used alternately, one filter separating the water soluble NaK hydroxide particulates from the exhaust gas while the other filter is being flushed with water as a solvent to dissolve accumulated NaK hydroxide thereby regenerating the filter.

Abstract: The air hammer is of the type employing a body having a first portion with a central bore and a piston reciprocable in the bore by pressurized air under control of an automatic valve. The body has a second or muffler portion which embraces the first portion and is operative to muffle the noise created by exhaust air from the bore. The muffler portion is provided with pressurized air passage means through which the pressurized air must pass for causing operation of the piston. The passage means are so arranged that removal of the muffler portion from the body disrupts the supply of pressurized air to the piston and thereby renders the hammer inoperative. Headers are provided on the ends of the body and are drawn tightly against the ends of the muffler portion by tie bolts which extend through through-passages, respectively, in the muffler portion.
