Abstract: This invention provides a carrying case made up of two sections of molded plastic which are identical except at their outer edges which meet when the case is closed. One edge includes a tongue with reinforcing ribs which enters a groove in the outer edge to engage a gasket and form a fluid seal as well as strengthening the case. Nothing penetrates the wall of the case, the latches being connected to supports spaced outwardly from the case wall. Sockets on the bottom of the case receive spaced support members projecting from a luggage cart, and can receive connecting elements to enable the cart to carry more than one case. The sockets also can receive wheel units so that a single case may be mounted on wheels, or a plurality of cases may be connected and supported on a set of wheels. The case includes integral feet on the bottom wall to support it, and bosses on the inner walls for connecting items to the interior of the case.

Abstract: This invention provides a fastener having a shank with a relatively abrupt transition from an unthreaded portion to a full thread dimension, the thread runout occupying no more than one pitch length of the thread in the axial dimension, and circumferentially extending no more than about one-fourth of the circumference of the thread at its pitch diameter. The counterbore of the nut is reduced in length in light of the short transition section of the shank. The threads are rolled on the shank by opposed dies having ridges complementary to the thread to be produced which run out at one edge of the die with spaced, generally symmetrical end walls which are relatively short axially of the ridges so that the full thread dimension is achieved abruptly.

Abstract: A syringe for sampling blood has a handle driven plunger in which is mounted an air permeable filter in communication with a valve chamber. In the chamber is mounted a gravity driven steel ball that is heavy enough to enable the syringe to be used in aspiration, with the ball remaining seated to block the air flow through the valve, and yet light enough to be used in taking of a normal pressure arterial blood sample during which air flow through the filter will drive the ball from its seat.

Abstract: The fastener includes a nut, a basket, and a sleeve, the latter being received in an opening in a workpiece with its outer end flared to form an attaching flange. Spaced rounded lobes on the sleeve extend the full length of the opening and become embedded in the wall of the opening. The sleeve includes a corner surface adjacent its head which compresses and deforms the workpiece at one corner of the opening. A tool having an annular bulge is forced into the sleeve to expand it against the wall of the opening. When the end of the sleeve is flared to form the attacking flange, the other corner of the opening in the workpiece is compressed and cold-worked. The forces exerted by the sleeve on the workpiece greatly increase the fatigue life of the workpiece.

Abstract: This invention provides a hanger supporting device for a garment bag which will accommodate both ordinary hangers and luggage-type hangers. The device includes a plate attachable to a garment bag, a first channel connected to the plate, a second channel carried by the first channel, a third channel pivotally connected to the second channel, and a rail connected to the second channel. The rail is adapted to engage luggage-type hangers. A pad having a notched surface is carried by the third channel and adapted to support ordinary hangers. A latching arrangement releasably holds the third channel adjacent the first channel to retain the hanger in the notches in the pad.

Abstract: A building temperature control system is velocity based, employing the velocity of air flowing into individual zones of temperature control to control temperature of the individual zones, total amount of air supplied to all zones from the air supply system, and the number of heating or cooling units in operation. Set point temperature for a particular zone is compared with actual temperature to generate a target velocity signal proportional to the temperature error. The target velocity signal is compared with actual flow velocity measured by the zone velocity sensor, and the difference between target and sensed velocity is employed to operate an air flow control damper valve until velocity of air flowing into the temperature control zone is equal to the target velocity.

Abstract: A launching system is provided having a launch cylinder with an open bottom and propulsion means in the form of a rocket motor attached within the cylinder adjacent the top thereof. The cylinder is formed of a lightweight material which floats with a substantial portion thereof beneath the surface of the sea. The spacecraft is attached to the upper end of the cylinder in a vertical position for launching. Water cooling apparatus is provided for cooling the cylinder walls in proximity to the exhaust gases. On initial firing of the rocket motor, the hot exhaust gases from the rocket motor are confined therebelow and create expanding pressure within the cylinder in the space above the water surface, while generating steam, which also expands, thus lifting the cylinder and spacecraft from the water until approximately three-quarters of the cylinder is out of the sea. Thereafter, the engines of the spacecraft are ignited, while release of the craft from the cylinder is effected.

Abstract: An emergency potable water supply system including a generally cylindrical water tank seated on a base member, with the tank having opposite dome-shaped portions. An inlet and discharge fitting is received in an opening in the uppermost part of the upper dome shaped portion, and a drain fitting is received in the lowermost part of the inverted dome-shaped bottom portion. All external connection fittings are conventional garden hose fittings, with the inlet fitting adapted for coupling, via a hose, to a standard exterior residential faucet. A check valve is provided at the inlet fitting, to serve as an anti-siphon valve in the event of a pressure drop at the inlet, and to serve as a vacuum release for discharge of the contents of the tank when needed. A garden hose is coupled to the outlet fitting for continual replenishment of the supply of water during use of the garden hose for normal tasks such as watering plants and shrubs.

Abstract: A safe construction having a liner configured for forming a valuables chamber with an access opening, the liner being positioned within a cavity in the ground with rebar assemblies adjustably connected to a framework secured to and supporting the liner within the cavity, the rebar assemblies each including first and second rebar sections with a rust resistant coupler interconnecting the two, the coupler being formed preferably of plastic with axially aligned but separated openings, each opening being configured for receiving an end of one of the rebar sections. The rebar assemblies are driven into the ground with the coupler at a position for being totally, or at least partially embedded in the poured concrete for deterring the formation of rust on the rebar sections within the concrete.

Abstract: A pilot-operated diaphragm valve in which the diaphragm seats on a valve seat having an unconstricted flow annulus therearound, and support regions are provided on the valve seat and on the valve body for support of the diaphragm when in closed position. The support region on the valve seat further performs important sealing functions, as does a sealing lip disposed radially-inwardly of the sealing and support region of the valve seat. To stabilize the diaphragm at various partially and fully open positions, and to augment sealing action when the valve is closed, a spring-pressed poppet is disposed above the diaphragm and is guided by a valve stem and bearing. A peripheral region of the poppet bears a certain relationship to the sealing portions of the valve seat.

Abstract: A safe having a valuables chamber with an access opening with inwardly extending ledges for placement of a plate-shaped separate steel door thereon, and a set of grooves formed on opposing walls retaining the door therein, the width of the grooves being a distance slightly more than the thickness of the door, with one groove being substantially greater than the depth of the other, with one edge of the door being inserted on a slight angle into the deeper groove while the other edge is pivoted toward the ledge, the door then being laterally displaced until the latter edge is in abutment with the seat of the shallower groove. A lock assembly on the reverse side of the door has the latch bolt engaging a detent in a metal bar for prevention of lateral movement with reinforcing bolts adjacent the lock bolt preventing force on the lock mechanism in the event of forceful intrusion attempts.
