A clamp mountable on a corner of a bin to secure a bag to the bin includes a top portion and a bottom portion moveable in a sliding relationship relative to the top portion. The top portion has a first and second inner clamp members arranged orthogonally relative to one another. The first and second inner clamp members extend downward from a bottom surface of the top portion and are configured to be located on adjacent inner walls of the bin. The bottom portion has a first and second outer clamp members arranged orthogonally relative to one another. The first and second outer clamp members extend downward from a bottom surface of the bottom portion. The first and second inner clamp members are aligned with the first and second outer clamp members, respectively, to pinch a wall of the bin.

An oval gear set for use in a flow meter comprises first and second gears that are identical to each other and that are configured to engage at a fixed center-to-center distance such that the first and second gears mesh at all angular positions. Each gear of the oval gear set comprises a hub and a plurality of gear teeth. The hub comprises an oval body having a major axis and a minor axis extending through a center of the hub, and a root profile wall circumscribing the major and minor axes. The plurality of gear teeth extend from the root profile wall. Each of the gear teeth has a pair of contact surfaces with circular involute curve profiles.

A valve comprises a valve cartridge, a valve stem and a valve seal. The valve cartridge comprises a generally cylindrical cartridge body, a bore extending longitudinally through the cartridge body, and an outlet passage and intermittent inlet passages extending through a side wall of the cartridge body to intersect the bore. The valve stem comprises an elongate body configured to slide within the bore, and a neck and a seal channel circumscribing the elongate body. The valve seal is seated within the seal channel. The valve stem slides within the bore to move the seal channel past the inlet passages. Portions of the cartridge body between the inlet passages retain the valve seal within the valve channel until the inlet passages are open to the neck. In one embodiment, the inlet passages form a crenelated edge. In another embodiment, the inlet passages form a ported end.

Seal-retaining valve for fluid metering device

A hand-held flow metering device for dispensing a pressurized fluid comprises a valve, a flow meter, a trigger lever, a trigger release mechanism and meter electronics. The valve is connected to the pressurized fluid to regulate flow of the pressurized fluid through the device. The flow meter is disposed within the flow of pressurized fluid to measure volumetric flow of the pressurized fluid. The trigger lever is configured to be manually displaced to mechanically open the valve. The trigger release mechanism is connected to the trigger lever and is selectively actuated to mechanically prevent the trigger lever from opening the valve when the trigger lever is displaced. The meter electronics is connected to the flow meter and the trigger release mechanism to actuate the trigger release mechanism based on output of the flow meter.

Lubrication dispense valve

Lubricant dispenser

Airless spray pump

The nozzle is designed for fitting on the end of a metered dispense valve which is used in fluid delivery systems such as lubricant dispensers for use in vehicle servicing and the like. The device in this application accommodates thermal expansion between the meter and nozzle by providing an air pocket which may absorb the thermal expansion.
