A container for storing and dispensing respiratory mask liners includes a housing defining a cavity therein and a cover arranged to be received on the housing, the cover including an upper face having an opening formed therein. The container further includes a lever having a first end and a second end, the lever first end pivotally connected to the cover for engaging and dispensing respiratory mask liners stored within the container through the opening.

A system and method for determining a liquid level in a vessel is described. Embodiments of the system can include a liquid level measuring assembly, a user device, and a vessel. The liquid level measuring assembly can include an ultrasonic sensor assembly, a control module, and a mount body configured to place the ultrasonic sensor assembly proximate a bottom of a vessel. Typically, the system can be implemented with a vessel having a substantially cylindrical shape and including a chime. The mount body can be adapted to removably couple to the inside of the chime of the vessel.

A cable and pulley or guide apparatus for accurately tuning and securing a tunable vibrating membrane on a cylindrical shell by means of a plurality of either fixed-angle pulley or guide assemblies not parallel to the top-bottom axis of the shell, or adjustable-angle pulley or guide assemblies not parallel to the top-bottom axis of the shell, built into or attached to purpose built hoops, attached to hoops with protruding flanges through holes or slots, or attached to a claw or hook apparatus which secures over the edge of annular hoops, through which a cable is laced and fed into the tensioning mechanism(s) to increase or decrease the tension on the cable, thus tensioning the vibrating membrane or heads against the shell, the angles of the pulley or guide assemblies adjustable to conform to the natural angle of the cable traversing the circumference of the shell.

A cable and pulley operated membrane tuning system suitable for drums and other musical instruments, as well as other applications requiring tunable membranes. The cable is threaded through pulleys or guides attached the mounting assembly of the membrane, and tightened by means of a tensioning mechanism. The system tensions membrane by varying the tension on the cable. The system may be employed in single-membrane systems or in multiple membrane systems.

A liquid delivery device for killing weeds. The liquid delivery device includes a main tube, a handle, and a pump housing that includes a pump chamber. A reservoir is disposed in the main tube, and a plunger is connected to the reservoir and positioned in the pump chamber. The plunger is operative to push a liquid contained in the pump chamber through a check valve and dispensing orifices when a user moves the reservoir with respect to the main tube and pump housing. The device also includes a spike extending from the pump housing and an annular stand-off surrounding the spike. The spike is adapted to disrupt the soil and damage the root structure of a target weed.

The invention provides a method by which high moisture low rank coal or other carbonaceous material may be transformed into a high-energy, water resistant product. The raw feed is comminuted then mechanically compacted by a roller press with rolls of a specified profile to mobilize the inherent moisture and collapse most of the interstitial pore space. The mobilized moisture is then removed by low-temperature drying and the material is sized and shaped to form a product that is resistant to re-absorption of water or other liquids. The present invention will promote the use of low rank coal for liquefaction and gasification.
