  • Patent number: 9709189
    Abstract: A valve, including a diaphragm valve, is provided featuring a cover in combination with at least one inner housing component. The cover may be configured with a biased-pin mounted therein. The at least one inner housing component may be configured with a hole or slot formed at a predetermined location where the biased-pin is at when the valve is calibrated to be at a final position. The cover may be configured to rotate and cause an axial translation between the cover and the at least one inner housing component so that the biased-pin engages the hole or slot when the valve is at the final position so as to stop any further axial and rotational movement.

  • Publication number: 20150075647
    Abstract: A lockable pipe cover includes an inner cap and an outer cover which are selectively coupled together for axial rotation. When the cap is locked, the inner cap and the outer cover are free to rotate independently from one another thus rotation of the outer cover will not remove the cap from the pipe. In the unlocked position, the inner cap and the outer cover are coupled for rotation and thus rotation of the outer cover results in rotation of the inner cap.

  • Publication number: 20150014065
    Abstract: A valve assembly for use in an inner tube member of a core barrel head assembly positionable within a drill string of a drilling apparatus. The valve assembly works using two separate surfaces and a biasing element with a force. When hydrostatic pressure is present forces are created on these surfaces, these forces have a direct relationship with pressure, as an increase in pressure will increase the force and vice versa. The surface areas are designed such that the valve will maintain closed while under a predetermined fluid pressure, indicating to the driller that the inner tube has landed. When the driller relieves the fluid pressure and the pressure decreases, the force difference between the respective forces decreases until the valve opens for drilling through the force from the biasing element.

  • Patent number: 8893534
    Abstract: A yard hydrant locking collar has two C-shaped steel hardened plates connected together at one end by a rivet. The rivet acts like a hinge and allows the top and bottom plates to swivel open and closed. The other end of each top and bottom plates has a locking hole. A one inch tapered slot is cut into the top plate near the locking hole. The top and bottom plates are rotated so the collar fits around the hydrant pipe. The locking holes and slot are positioned near the hydrant locking hole and the collar locking holes are aligned. A padlock is opened and tilted away from the pipe and the free arm of the padlock is placed through the locking hole of the hydrant handle and positioned over the locking holes of the collar. The padlock is then tilted back towards the pipe. The tapered slot allows the padlock to move towards the pipe so that the free end of the padlock can move through the locking holes. Once the free end of the padlock passes through the collar locking holes, the padlock can be raised and locked.

In one embodiment provided, the removable lockable cap is lifted from the dump station inlet line by a remote foot pedal—this allows for a cleaner and more efficient means for inserting the hose from the waste tank of a vehicle into the dump station inlet line. Money payment can be either made by cash or by credit or debit cards. The operation of the dump station is made more efficient and requires fewer interactions between those who need to transfer waste from their vehicle waste tanks, such as operators of campers or recreational vehicles, and the dump station operator. Remote sensors can also be deployed to minimize the possibility of spillage or over-fill of the dump station if the dump station is not hooked up to a sewer system.

    Abstract: The latching gas ON/OFF assembly includes a housing with a female threaded bore for receiving a male threaded neck of a gas tank cylinder having a tank valve with a pin. A bonnet is slidably connected to the housing and slides between a forward OFF position and rearward ON position. A pin depressor connected to the bonnet with a transverse latch button for locking the bonnet in the ON position and for releasing the bonnet from the ON position. When the bonnet is slid to the rearward ON position it causes the pin depressor to contact the pin of the tank valve to permit gas to flow therefrom. The latching button is spring-biased toward a locked position where a plate on the free end thereof removably resides in a complementary seat in the housing.

  • Patent number: 7874311
    Abstract: A locking device for water valves having an actuation mechanism that couples to the water valve nut to secure the water valve. The actuation mechanism is contained within a container to limit access. The actuation mechanism is activated by a member that can be positioned in engagement with the actuation mechanism or out of engagement with the actuation mechanism. When position out of engagement with the actuation mechanism, the member can be secured to inhibit unauthorized access to the water valve nut.

  • Patent number: 7845367
    Abstract: A lock device includes a first bracket 34 fixed to a screw element 33 and formed with a lock hole 34b; a second bracket 35 which has a fitting portion 35a fitted to the turn-type control lever 30 of an operation pattern selecting valve 16 and which is formed with a lock hole 35f; and a lock 36. The screw element 33 is screwed into a threaded hole 32 formed in an end plate 29 of the operation pattern selecting valve 16 to secure the first bracket 34 to the end plate 29. The fitting portion 35a of the second bracket 35 is fitted to the turn-type control lever 30 to connect the second bracket 35 to the turn-type control lever 30. The lock 36 is insertably attached to the respective lock holes 34b and 35f of the first bracket 34 and second bracket 35 for locking the turn-type control lever 30. With such a structure, the lock device can be manufactured relatively easily without the necessity of processing the operation pattern selecting valve.

  • Patent number: 7771381
    Abstract: A locking assembly is provided to simply and effectively prevent any unintentional adjustment of the adjustable valve mechanism in a fluid flow control device, without compromising the function of the device. The locking assembly generally includes at least one gripping arm for frictionally engaging at least a portion of the adjustable valve mechanism, and an actuating mechanism for controlling the deployment and release of the gripping arm. The locking assembly prevents unintentional adjustments that can adversely affect the pressure settings of the fluid flow control device. In particular, the locking assembly prevents unintentional adjustment, such as may be caused by the presence of a strong external magnetic field. The locking assembly can be easily disengaged, such as through the application or removal of an external mechanical force, to allow a clinician to adjust the pressure settings of the fluid flow control device as necessary.

  • Publication number: 20090205722
    Abstract: An apparatus is provided which prevents the removal of a companion fitting when the valve is open. Thus, for example there is disclosed a load line apparatus comprising a housing, a valve, a cam lever, or more likely a pair of cam levers, and a locking device. The housing has an interior bore, the interior bore defining a flow-through passage. The valve has a surface shaped to close the flow-through passage when the valve is closed. The cam lever is pivotally attached to the housing, and the locking device is movable by the cam lever. The cam lever is operable between a locked position and an unlocked position. In the locked position, the locking device forms a stop to prevent the valve being opened. In the unlocked position, the locking device is retracted from the locked position. The cam lever is operable from the unlocked position into the locked position only when the valve is closed. The load line apparatus disclosed prevents the valve from being opened unless the cam lever is the unlocked position.
