  • Patent number: 4027708
    Abstract: A control system for a gasoline dispensing nozzle which includes a locking system for placing the nozzle in an inoperative mode once the nozzle automatically shuts off. Resetting of the locking system is then required before operation of the nozzle can again be commenced. The locking system includes a biased member which maintains the automatic shut-off system in its disabling mode once it disables the nozzle. This locking system is designed primarily for use on a dispensing nozzle with a vapor receiving system and is used to discourage an operator of the nozzle from overfilling a gasoline tank, which results in increasing the risk of spilling gasoline or forcing gasoline back through the vapor return line. An alternative embodiment using magnetic locking means is also provided.

  • Patent number: 4028473
    Abstract: Liquids and semiliquids, such as thixotropic gels, oil and greases, are delivered to a discharge means according to a method and through the use of an apparatus powered by hydraulic fluid under pressure which is controlled by a valve for passage to a hydraulic motor that is, in turn, coupled to a pump used to withdraw and pressurize the material for delivery by a conduit line to the discharge means having a discharge orifice that is either nonclosable or synchronously opened. The material is discharged by controlled pressurization which is initiated and terminated by controlling the flow of hydraulic fluid to the hydraulic motor in response to actuation of a trigger or switch on the discharge means. A discharge gun and a lubricator collar are two preferred forms of the discharge means.

  • Patent number: 4024995
    Abstract: The invention contemplates an aerosol container construction, and in particular a dispensing cap construction for integration with or assembly to existing aerosol containers, whereby safety features are incorporated to materially reduce the hazard of child dispensing of harmful contents. The construction makes it necessary to follow a particular sequence of two different deliberate actuating displacements before any contents of the container can be dispensed, and the size and placement of manual-access surfaces for performing these displacements are such that a small child cannot make the requisite actuations with the fingers of one hand; on the other hand, these size and placement proportions are such as to readily accommodate adult use, with the fingers of one hand.

  • Patent number: 4023709
    Abstract: In an apparatus for the discontinuous dosing of a constant quantity of fluid into an analysis device, the fluid feed system is connected by means of a three-way valve on the one hand via the dosing valve and a shut off valve arranged downstream and on the other hand via a by-pass to the fluid discharge system. A compressed air source for the production of a constant air pressure is connected between the three-way valve and the dosing valve. All the components of the system are controlled by a programme control unit, so that the fluid flow through the dosing valve is temporarily interrupted by closing the shut off valve and switching over the fluid feed to the by-pass and at the same time releasing the connection of the compressed air to the dosing valve. Thereafter the compressed air source is switched off by the control unit and the interruption of the fluid flow at the dosing valve is cancelled.

  • Patent number: 4022355
    Abstract: A cartridge for containing and dispensing caulking compound comprises an elongated tubular member, generally cylindrical in configuration, one end of which has a fixed end wall including a dispensing opening therethrough and a spout attached to the end wall, while the other end of the tubular member is closed by a resilient, annular, floating member slidably mounted within the tubular member. The floating member is impervious and is made of a flexible material. When employed in conjunction with a standard caulking gun of the plunger type, the force of the plunger bears directly on the floating member which thereby expands in diameter and decreases in width and transmits pressure to the caulking for dispensing. When the plunger is suddenly withdrawn, the expansion of the floating member effectively absorbs the pressure forces within the cartridge thereby minimizing the amount of undesirable leakage of the caulking from the cartridge.
