  • Publication number: 20220112748
    Abstract: A multipoint door lock system comprises a door frame having a bolt opening and a secondary opening. A latch takes an activable position when the door is opened and a pre-armed position when the door is closed. A door-locking tip of the latch protrudes from the secondary opening of the door frame and into a secondary bore of the door when the door is closed. A transfer block moves from an inactive position to an active position upon insertion the deadbolt in the bolt opening. A biasing element causes a displacement of a translating member when the transfer block moves to the active position in the absence of a force sufficient to cause a compression of the biasing element. This action of the translating member locks the latch in its pre-armed position within the secondary bore.

  • Publication number: 20220112749
    Abstract: An adapter and interface permits a standard mortise lock to drive top and bottom latch mechanisms of a multi-point lock system. An actuator permits in situ adjustment of the top and bottom vertical latch projections of adjusting these projections while the door is hung in the door frame. An installation tool assists in the installation of the vertical rods in a door. A connector and carrier secures the vertical rods to the actuator and permits verification of retention of the rods in a multi-point latching system. A latch dogging indicator allows for end-user adjustment between a single-point lock and a multi-point lock system when desired. These different aspects may be employed in combination or separately with other locking systems.

  • Publication number: 20220112750
    Abstract: The invention consists of a novel cooler hinge construction that allows for the cooler's lid to be removed and reattached easily. One benefit of such an assembly is that either side of the lid may be used facing upwards, depending on what the user is doing at the time. The lid is attached to the hinge by a clamp assembly that pinches the lid and holds it in place. The jaws of the clamp are housed within identical grooves on the top and bottom of the lid, allowing the lid to be pulled out of the clamp when the cooler is open and to be subsequently reattached by sliding the lid back into the clamp. This functionality allows for the lid to be removed and reattached easily, but also holds it securely in place when the cooler is closed because the lid is unable to move laterally. The clamp also serves as a controlled fail point for the invention, allowing the lid to break away before the hinge or clamp are damaged.

    Abstract: System and methods for using channel quality reports to reduce inter-band interference are disclosed. Channel information is received at a first wireless communication device from a second wireless communication device. The first wireless device is operating in a first frequency range, and the second wireless device is operating in a second frequency range. The first frequency range is adjacent to the second frequency range. A channel quality report is generated at the first wireless communication device. The channel quality report indicates that particular sub-bands in the first frequency range have low channel quality. The particular sub-bands are selected using the channel information.

  • Publication number: 20220112778
    Abstract: Techniques described herein relate to a method for identifying downhole conditions during a drilling operation using a vibratory separator. The method includes calibrating a sensor system attached to the vibratory separator by periodically measuring the G-force acting on the vibratory separator functioning under steady-state operating parameters. The method also includes determining the relationship between the G-force acting on the vibratory separator and the flow rate and rate of penetration (ROP) for the drilling operation by measuring the G-force acting on the vibratory separator functioning under different non-steady-state operating parameters.

    Abstract: A method can include directing fluid flow longitudinally through a well tool connected in a tubular string downstream of a longitudinally compressed circulating valve assembly, thereby causing the well tool to operate, and longitudinally elongating the circulating valve assembly while the fluid flow is ceased, and then increasing the fluid flow, thereby causing the fluid flow after the elongating to pass outwardly through a housing of the circulating valve assembly to an external annulus. Another method can include directing a fluid flow through a well tool connected in a tubular string downstream of a circulating valve assembly, thereby causing the well tool to operate, and decreasing then increasing a flow rate of the fluid flow, thereby causing the fluid flow to pass outwardly through a housing assembly of the circulating valve assembly to an external annulus. Circulating valve assemblies are also disclosed.
