Abstract: A liquid dispensing nozzle has an annular member of a relatively soft material at one end of a bellows, which is disposed in spaced relation to the spout of the nozzle to form an annular vapor return passage therebetween, to engage the fill pipe to form a seal therewith when the spout is disposed therein so that the vapors flow from the tank to the annular vapor return pasage of the nozzle. The soft seal member is removably fastened to the end of the bellows for easy replacement. The spout has a pair of latch rings thereon spaced from each other with each having a retaining lug to enable the spout to be retained within any type of fill pipe since one of the lugs on one of the latch rings is always capable of being retained by the lip of the fill pipe opening.

Abstract: The bolt of a latching mechanism is spring actuated toward a latching position relative to the latch-receptive slot of a latch-catch which is pivotally mounted on the vertical member of a swing gate, and movement of the bolt from a fully latched position to a retracted non-latching position is controlled by a pendulum stop which is normally and gravitationally disposed in interfering relationship with the bolt, whereby an intentional, deliberate, pendulum-stop-displacing action is required on the part of an attendant in order to enable the bolt to be shifted from an advanced, locked position to a retracted position.

Abstract: A tightly coiled, substantially cylindrical wick of compressed, dehydrated, sponge-like material having sufficient rigidity to be inserted endwise into an ear canal will, when hydrated, uncoil and expand radially whereby to substantially engage the inner surface of the ear canal for applying medicament to said inner surface while securing it against accidental or unintentional dislodgment therefrom. When hydrated, a central opening is provided through the uncoiled member through which opening sound waves may freely pass en route to the ear drum.

Abstract: A variety of substances are known which induce or alter host resistance to coccic and bacillic infections. It is also known that treatment is complicated by the ability of such organisms to develop resistance to antimicrobials. Numerous strains are known which elaborate enzymes in response to these drugs and thus remain insensitive to them. Hence there appears to be a never-ending demand for anti-coccic and anti-bacillic factors. Certain substituted para-aminobenzoic acids are shown herein to render the host immune to such strains.

Abstract: An automatic shut-off nozzle has its valve, which controls liquid flow from its inlet to its outlet, arranged to provide a minimum flow rate to prevent recycling of fuel irrespective of the angle of the fill pipe.

Abstract: In an automatic shut-off nozzle, the vacuum chamber, which has its vacuum increased when flow through the nozzle is to be stopped in response to a predetermined condition such as the tank being filled to a predetermined level, for example, has the reduction in the vacuum therein controlled so that the automatic shut-off mechanism cannot be returned to its latching position by the attendant for a predetermined period of time after having been activated. A check valve allows removal of air from the chamber to increase the vacuum in response to the predetermined condition while preventing flow of air into the chamber. The flow of air into the chamber to reduce the vacuum therein must be through metering means so that a predetermined period of time must elapse until the vacuum in the chamber has been reduced by the air flow through the metering means to enable the shut-off mechanism to be latched.

Abstract: An automatic shut-off nozzle has a venturi effect, which causes automatic shut off of the liquid flow through the nozzle body by causing a main poppet valve to be closed when the tank is filled, created by two aligned passages of different diameters in either the resiliently biased bleeder poppet valve, which opens in response to the pressure of the fluid flowing through the nozzle body, or the seat ring for the bleeder poppet valve. The smaller diameter passage has the liquid enter its inlet with the liquid exiting through the outlet of the larger diameter passage with the larger diameter passage also communicating with the vacuum chamber in which the vacuum is increased by the venturi when the tank is filled to cause automatic closing of the main poppet valve in the nozzle body.

Abstract: A tennis racket and stringing method are disclosed wherein the resulting racket has a more uniform main string to cross string tensioning. The uniform tensioning provides a consistent playing surface throughout the entire stringed area. The center main strings are first tensioned and the remaining main strings are tensioned by working outwardly from the center strings toward the sides. The cross strings are interwoven with the main strings beginning from the center and working outwardly.

Abstract: Liquid flow through an automatic shut-off nozzle is automatically stopped when liquid is present at a predetermined location in the vapor return means. The automatic shut-off nozzle also stops flow in response to the tank being filled to a predetermined level with liquid or the pressure in the tank exceeding a predetermined pressure.

Abstract: A swivel connector comprises three hollow members with the first and second members rotatably connected to each other for rotation about a first axis and the second and third members rotatably connected to each other for rotation about a second axis at an angle to the first axis. The first member has adjustable members for connection to the gasoline supply and vapor return passages of a gasoline dispensing nozzle body. The third member has the gasoline supply and vapor return hoses, which are connected to the pump pedestal, connected thereto. A hollow tubular member is supported in the first and third members and extends through the second member to provide the passage for the gasoline supply within the swivel connector while the space between the inner walls of the first, second, and third members and the outer surface of the hollow tubular member provides the vapor return passage within the swivel connector.

Abstract: An air purification system accepts foul air from a source of high pressure and treats the air so as to deliver an acceptable breathable air usable in any life support package. The components of the system are mounted on a portable cart. The foul air passes through a plurality of stages in going from the foul to the usable condition. The air is monitored at the various positions along the system to insure that the system is operational.

Abstract: A swivel connector between a flexible hose and a nozzle has a reduced portion of a first body secured to the nozzle and an enlarged portion of a second body secured to the hose with the first and second bodies, which have an enlarged portion of the first body overlapping a reduced portion of the second body, providing aligned passages therethrough to provide communication between the hose and the nozzle. A plastic thrust bearing is disposed between a metallic ring secured by set screws to the enlarged portion of the first body and a metallic ring mounted by flats on the ring cooperating with flats on the reduced portion of the second body so that each of the rings rotates with the body to which it is connected.

Abstract: An indicating gauge has dual floats to measure the levels of two liquids contained in the same tank. A separate measuring tape is controlled by each float to provide an indication of the liquid level through a single viewing window above the tank. In certain situations, a single float and measuring tape is used to provide an indication of the level of one liquid within the tank. A wiper is engageable with the viewing window to permit cleaning of the inside surface of the window.

Abstract: A vapor recovery adapter has a housing supported on a storage tank having a volatile liquid therein. The housing is connected to other tanks, which also are vented by the adapter in addition to the tank on which the housing is mounted, through an inlet port perpendicular to an inlet port communicating with the tank on which the housing is mounted. Diametrically disposed to the inlet port to the other tanks is a first outlet port through which all of the tanks are vented when not being filled and through which any of the tanks can receive air when liquid is being withdrawn therefrom. The first outlet port is blocked by slidable valve means in the housing when any tank is to be filled and a second outlet port at the top of the housing is opened to allow the vapor to be vented from any tank being filled to a truck tank from which the tank is being filled so that there is no exhaust of vapor to the atmosphere.
