A dispensing assembly is provided for a container of fluent material. A hand-operable dispenser cartridge is adapted to be mounted to the container. An actuator, which may include a nozzle or spout, is mounted on the cartridge. A locking sleeve is mounted around the cartridge and has an upper abutment edge and a recess. The locking sleeve can be rotated between a first rotated position preventing actuation of the dispensing assembly and a second rotated position permitting actuation of the dispensing assembly.

A tamper evident cap assembly, more particularly a combination of vial and cap assembly, assures the integrity of a specimen and of the specimen collection process. The screw cap is locked to the screw threads of a vial, when the vial is empty, with one of two latches that are integral to the cap assembly and can lock the cap to the vial. The lock is broken in the presence of the specimen donor or in the presence of a witness who can testify as to chain of custody, a specimen is placed in the vial, following which the cap is locked to the vial with the other of the two latches, which is broken when received by a testing laboratory. A loop formed to encircle the vial is connected by a tether to the cap and slipped onto the vial. At least one restraining rib on the vial is spaced below the screw thread top and is sized to permit the loop to be forced upwardly thereover to be restrained from downward movement. In addition, a limiting flange on the vial is spaced below the screw thread and above the loop restraining rib sufficient to accommodate the loop, and is sized to limit upward movement of the loop. In a specific embodiment, latch staples extend from the cap which can be inserted into, and irreversibly lock with, respective hasps extending from the loop.

An aircraft cargo carrier restraint device that is constructed so that it cannot be accidentally moved from extended, pallet locking position to a retracted position. The device embodies locking pawls of unique design that positively preclude movement of the pawls into a retracted position unless a specific sequence of operation is followed. One of the locking pawls includes a locking notch and the other of the locking pawls includes a locking protuberance, which is closely received within the locking notch so as to positively prevent accidental downward movement of the pawls into their lowered position.

A dispensing assembly is provided for a container of fluent material. A hand-operable dispenser cartridge is adapted to be mounted to the container. An actuator with a lateral projection, which may be a nozzle or spout, is mounted on the cartridge. A locking sleeve is mounted around the cartridge and has an upper abutment edge and a recess. The locking sleeve can be rotated between a first rotated position preventing actuation of the dispenser and a second rotated position permitting actuation of the dispenser.

A catch member (14) extending in the width direction of a seat cushion (1) is arranged inside a front portion of the seat cushion (1) and is supported so as to be vertically movable. There are also provided a torsion spring (16) for urging the catch member (14) to move upward and a pendulum member (18) for operating with an inertial force upon an abrupt deceleration to inhibit vertical movement of the catch part. When a passenger sits on the seat cushion (1), the catch member (14) moves downward to preclude deterioration in seating comfort. When the passenger's rear end (22) starts to move forward upon an abrupt deceleration, the catch member (14) is locked and the rear end (22) is caught by the catch member (14). This makes it possible to suppressed the forward movement of the passenger with reliability, and allow lightweight and low-cost configuration with simple configuration.

The adjusting lever is moved along with the basket. Consequently, in the present invention, the thumb of a user is not caught in the basket and injured when the user rotates the adjusting lever.

A manual seat height adjuster mechanism for a seat of a vehicle includes a freewheel brake mechanism having a rotatable output pinion to engage and rotate an adjustment component of the seat to adjust a height of the seat and a locking mechanism selectively engagable and disengageable with the freewheel brake mechanism to allow the height of the seat to be adjusted and to prevent the height of the seat from moving once the height has been adjusted.

A latch for mounting a suppressor to a firearm is disclosed that allows interfacing with and securely attaching to the weapon's flash hider without the need to use threads and the rotational movement commonly associated with attaching suppressors to a firearm. The latch consists of a primary latch and a secondary latch. The primary latch moves in a vertical plane, fits into the grooves on a standard flash hider, and is rotationally indexed to the flash hider when locked. The secondary latch attaches to the top of the primary latch, securing the primary latch when it is fully locked by pivoting around and downwards, and locking to the suppressor. The primary latch compensates for the considerable tolerance range of the outside diameter of the flash hider. The latch has minimal thermal coupling to the suppressor and engaging / disengaging the primary latch plate and the secondary latch can be accomplished with one hand.

A watercraft lift for raising and lowering a watercraft in water, including a buoyant pontoon, a lifting cradle and at least one pivot arm. The lifting cradle includes at least one air tank and a support bunk configured to receive and support the watercraft. The air tank has an internal chamber configured to receive and release pressurized air. The internal chamber has sufficient internal volume that when sufficient pressurized air is received therein the air tank has sufficient buoyancy to lift the lifting cradle to a raised position with the watercraft out of the water when positioned on the support bunk and that when sufficient pressurized air is released from the internal chamber the air tank loses sufficient buoyancy to sink the lifting cradle to a lowered position sufficiently submerged to receive and deploy the watercraft. The pivot arm is pivotally connected to the pontoon and pivotally connected to the lifting cradle to guide movement of the lifting cradle between the lowered position and the raised position.

A ladder rest and restraining device is provided for the edge of a roof or other elevated structure which is regularly or periodically accessed by means of an extension ladder or other similar device.

To help hold a trailer bed of a truck steady at a loading dock as the truck is being loaded or unloaded of its cargo, a yieldable vehicle brace exerts a substantial, but limited, reactive force upward against the trailer's rear impact guard to resist the trailer's downward movement. In some embodiments, the brace holds the trailer bed stationary up to a certain load limit and provides the trailer bed with a controlled or dampened descent when the load exceeds that limit. In some cases, the reactive upward force exerted by the brace increases with the downward velocity of the trailer bed. The reactive force can be created by one or more pressure relief valves, hydraulic fluid passing through a flow restriction, a brake, a spring, or various combinations thereof. Some embodiments of the brace include provisions for accommodating horizontal movement of the rear impact guard.
