Abstract: The spray head for a pre-rinse assembly includes a discharge cover having a plurality of ports for discharging water and a diffuser within discharge cover having a circumferential wall with at least one slot for directing a jet of water onto the fins of a rotatable impeller within the diffuser. The impeller has a plurality of tabs disposed relative to the ports whereby a respective tab momentarily covers a respective port to prevent passage of water therethrough during rotation of said impeller thereby effecting a pulsating stream of water through a respective port.

Abstract: The panel fastener has two components, each of which is mounted on an end piece of a wall panel and which are slid together to secure adjacent wall panels together. The two components have mating shapes that cause the components to move towards each other as components slide together in order to move and secure the pair of panels together in a tightened manner.

Abstract: The valve assembly employs a remotely located button to open normally closed solenoid valves in the cold water line and hot water line via an electronic control module. In response to a second signal from the button, the control module causes the solenoid valves to close. A metering valve senses the flow rate of cold water and issues a signal in response to the flow rate being below a minimum flow rate to the control module to close the solenoid valves to block further delivery of water.

Abstract: The hinge has a bracket for mounting on a door frame, an adjusting plate for securement to a door, a flange pivotally mounted on the bracket and disposed over the adjusting plate and captive nut assemblies for securing the flange to the adjusting plate in a releasable longitudinally adjustable manner. Loosening of the captive nut assemblies allows the door to be moved laterally of the frame before tightening of the captive nut assemblies fixes the door relative to the frame.

Abstract: The leg socket has a plurality of circumferentially spaced apart ribs extending along an interior wall. Each rib has a concavely curved surface extending longitudinally and disposed on a common radius of the wall to provide contact with a cylindrical table leg over a surface.

Abstract: The panel fastener has two components, each of which is mounted on an end piece of a wall panel and which are slid together to secure adjacent wall panels together. One component has a longitudinally disposed T-shaped slot and the second component has a T-shaped projection that slides within the slot of the first component to secure the wall panels together.

Abstract: The leg socket has a plurality of circumferentially spaced apart ribs extending along an interior wall. Each rib has a concavely curved surface extending longitudinally and disposed on a common radius of the wall to provide contact with a cylindrical table leg over a surface.

Abstract: An adjustable portable power tool guide having a base plate, a base plate cutting edge to define a cut line, an adjustable tool guide rail for guiding a portable power tool cutter adjacent to the cutting edge, and an adjustable control bar that defines a reliable and predetermined angle between the cutting edge and the control bar.

Abstract: A milk monitor with a sensor positioned near the milker unit to monitor milk conditions and adjust a variety of dairy facility operations in response to milk conditions. The milk monitor is programmable to provide flexibility, real-time adjustment of dairy operations, and trend analysis and control to optimize milk production and herd health.

Abstract: A livestock sorting system that uses an activity-based controller for receiving sort signals, opening a sort gate in response to each of said signals, and closing the sort gate only when no sort signals are pending.
