A method of loading stacked strainers in a dispenser while minimizing strainer contamination is disclosed. The method includes providing a stack of strainers that is enclosed in a protective material to form a pod, placing the pod within a dispenser, and removing the protective material from the pod of strainers while the strainers are in the dispenser. The strainers dispensed from the thus loaded dispenser avoid being contamination during loading. The protective material may be perforated to facilitate removal from the stack, and include an extended portion to be grasped during removal from the dispenser.

A coating apparatus includes an open/close valve having a motor that allows control of opening operation and closing operation in accordance with electric signals applied from a controller. The coating apparatus further includes a suck back valve having a motor that allows control of a volume variation in a flow path for suck back that is in communication with an upstream side and a downstream side of a pipe in accordance with electric signals. The controller allows control of start of the closing operation of the open/close valve and start of suction operation of the suck back valve through application of the electric signals to the motors, respectively. This achieves simple adjustment of liquid cut-off.

A fluid dispensing apparatus includes a container defining an interior space for holding a fluid. The container is configured to separate the fluid into a liquid and a vapor such that at least a portion of the vapor is disposed above the liquid. The container includes a sidewall and a top wall connected to the sidewall. A fluid inlet and a fluid outlet are disposed in the sidewall. A plurality of vapor valves are releasably connected to the top wall. The top wall includes a plurality of recesses and a plurality of passageways connecting the plurality of recesses to at least one outlet in the top wall. Each of the plurality of vapor valves is disposed within one of the plurality of recesses, and the plurality of vapor valves is configured to regulate the flow of fluid through the plurality of passageways and exhaust vapor disposed above the liquid.

A suppression unit includes a nozzle, an actuator piston, a casing, and a biasing device. The nozzle has an exterior surface, an interior bore extending along a longitudinal axis, and a plurality of discharge orifices passing from the interior bore to the exterior surface. The actuator piston includes an interior channel in fluid communication with the interior bore, the nozzle separably attached to the actuator piston. The actuator piston and the nozzle are disposed within the casing and the biasing device is compressible between the actuator piston and the casing. The discharge orifices are protected by the casing in a biased passive condition of the nozzle, and the discharge orifices are moved longitudinally out of the casing in an active condition of the nozzle.

Removable and replaceable outlets for point-of-use showers or faucets, filter devices, and methods and systems including the outlets and/or filter devices, are disclosed.

A system is provided for a cup used to supply a liquid to a spray tool. The system may include a cup, a filter configured to mount inside of the cup, one or more supports extending across the filter, and a retainer configured to retain the filter.

Provided is a pump apparatus, having an upstream pump, a filter, and a downstream pump being inserted into a processing liquid flow path in this order. The downstream pump has an inlet higher in level than an outlet of the upstream pump and higher in level than an outlet of the filter. That is, the downstream pump is disposed higher in level than the upstream pump and the filter. Accordingly, this allows a processing liquid to flow upward. Even when air bubbles are generated in the processing liquid, buoyancy causes the air bubbles to move upward in the processing liquid flow path and collect the air bubbles on a downstream side. Consequently, the air bubbles are readily vented from the processing liquid flow path.

In one aspect, the present disclosure relates to a bowling lane conditioning machine. The bowling lane conditioning machine has a drive mechanism for moving the conditioning machine along a bowling lane, a fluid storage tank that stores a conditioning fluid; a dispensing assembly for dispensing the conditioning fluid about the bowling lane; and a pump for moving the conditioning fluid along a flow path between the at least one fluid storage tank and the dispensing assembly. The conditioning machine further includes contaminant sensing assembly positioned along the flow path of the conditioning fluid for detection of one or more contaminants in the conditioning fluid. Other aspects also are described.
