Abstract: A container, for dispensing two substances simultaneously, that includes a neck portion having two orifices therein, a shoulder portion connected to the neck portion, and an elongated body portion connected to the shoulder portion, the body portion including two adjacent chambers sharing a common wall wherein each chamber is in fluid communication with an orifice in the neck portion, and wherein the two chambers are formed from different materials. The size and shape of the orifices can be varied to independently adjust the rate of dispensation of each of the two substances, or to compensate for variances in viscosity between the substances. The sizes of the two chambers can be varied independently from one another. Further, the two chambers can extend beyond the width of the common wall, to promote even and predictable deformation of the chambers when pressure is applied.

Abstract: A dry disconnect coupling connects the transfer hose from a fuel oil storage tank and the fill pipe of a tanker truck to form a continuous flow path between the storage tank and the tanker truck. The coupling includes an adapter, a coupler, and means for returning fuel residue to the flow path or to an external reservoir. The adapter is attached to the fill pipe of the tanker truck on one end and to the coupler on the other end. The free end of the coupler is attached to the transfer hose from the storage tank. The adapter and the coupler each define a flow passageway therethrough which is sealed by a poppet valve having an end face. The fuel returning means includes a reservoir for collecting fuel residue that accumulates on the end faces of the adapter and the coupler during transfer operations. In a preferred embodiment, the returning means includes a venturi vacuum for suctioning the fuel residue out of the reservoir and into the flow passageway defined by the coupler.

Abstract: A non-hydraulic injection blow molding machine for making hollow plastic articles. The machine has a parison mold having top and bottom portions for injecting a parison onto each of a plurality of core rods, and a blow mold having top and bottom portions for blowing the parisons into hollow work pieces. The articles are removed from the core rods at an eject station. The core rods are mounted on a turret. The turret rotates to advance the core rods from the parison mold to the blow mold, and from the blow mold to the eject station. The machine has a rotating crank shaft. A translating mechanism translates the rotation of the crank shaft to a vertical reciprocating motion. A clamp beam is connected to the translating mechanism and is actuated by rotation of the crank shaft to move between raised and lowered positions which are separated by a fixed stroke.

Abstract: An overfill prevention device for storage tanks includes an elongate tubular housing having a liquid flow passageway. A normally open main valve and a normally closed vapor retaining bleed valve are associated with the fluid passageway. Closure of the main valve interrupts the primary flow of liquid through the passageway and closure of the bleed valve prevents any further liquid from entering the tank and also prevents the escape of vapors from the tank. Operation of the main valve is controlled in significant part by a valve latch assembly which is carried by the housing and a relatch assembly which is carried by the main valve. The relatch assembly ensures operative engagement of the main valve with the valve latch assembly upon movement of the main valve from the intermediate position to the open position. Operation of the main valve and vapor retaining bleed valve is also controlled indirectly by a plurality of floats which are maintained in a float chamber extending adjacent the liquid passageway.

Abstract: A partially PTFE laminated rubber closure for pharmaceutical vials which resists undesired removal prior to placement of an aluminium over-cap on the vial and closure. The rubber closure includes a flat circular head which protrudes over the end of the pharmaceutical vial. Secured to the underside of the head is a cylindrical sealing portion which is partially laminated with PTFE at its lower end. Above the end of the PTFE on the outside of the sealing portion is a protruding ring of rubber. This ring allows good high friction contact between the closure and the vial which prevents the closure from dislodging during transportation of the vial after application of the closure and prior to application of an aluminum overcap. A method for making the closure is also provided.

Abstract: A fuel dispensing nozzle is disclosed and includes a main body portion containing a fuel passageway and a main valve controlling the flow of fuel through the fuel passageway. A lever extends from the body portion which is operable by the hand of a user holding the nozzle to open the main valve to allow fuel flow through the nozzle and a lever guard is attached to the body and extends around and under the lever. A hold-open clip is pivotally mounted to the lever guard. The lever includes notches which are positioned relative to the hold-open clip so that when the hold-open clip is rotated by the user into its operative position it may engage a notch in the lever and hold the lever in a position where the main valve is opened to allow fuel flow without requiring the user to continue to hold the lever. A removable lockout member is attached to the lever to prevent operation in the automatic hold-open mode by preventing engagement of the hold-open clip with a notch in the lever.

Abstract: A float chamber located in generally parallel, laterally spaced relationship to the main liquid flow passageway contains superimposed floats that move along a substantially linear path of travel. The floats cooperate with other control components to effect closure of a main valve assembly when the liquid level adjacent the mechanism reaches a preselected first elevation, and to close a bleed valve assembly when the liquid level reaches a second, higher elevation. The main valve assembly includes a movable plate valve that is spring biased toward an open position and that is biased toward a closed position by the force of liquid adjacent thereto and upstream therefrom. A latch and associated catch prevent movement of the valve plate to its closed position until such time as the liquid level reaches the first elevation.

Abstract: A fuel dispensing nozzle for refueling vehicles is disclosed. The nozzle provides a poppet valve for manually controlling the flow rate through the nozzle and an automatic flow control regulator for limiting the maximum flow rate through the nozzle to a predetermined maximum flow rate. The illustrated embodiment provides the automatic flow regulator in an existing passage within the nozzle body downstream from the poppet valve. Therefore, the regulator can be retrofitted into existing nozzles without separate fasteners or the like. The regulator includes a polymeric sleeve having lateral ports and a piston slidable in the sleeve providing an orifice around the operating rod of the poppet valve. A spring normally maintains the piston in its full open position. When flow rates approach the maximum desired predetermined flow rate, a pressure drop occurs through the orifice, producing a force overcoming the spring and causing the piston to move down and partially cover the ports in the sleeve.
