Abstract: An air washer comprises upper and lower plenum chambers which are separated by a panel which carries tubes. A spray nozzle above each tube is oriented to direct the conical spray it forms into the tube to wet the lower half of the bore of the tube. An inlet duct communicates with the lower plenum chamber. A tank is provided below the lower plenum chamber. Filter apparatus is provided in the tank. A fan communicates with the upper plenum chamber and draws air from the inlet duct via the plenum chambers and the parallel paths through the tubes. The air is washed by the spray formed by the nozzles which are fed with liquid drawn from the tank through the filter apparatus.

Abstract: Each line of a multi-line machine tool installation is provided with a sluiceway for receiving coolant/lubricant liquid drained from the machine tools of the line as well as for receiving swarf from those machine tools. Flushing jets are mounted at intervals along the line for flushing swarf along the sluiceway. Liquid supply to each flushing jet is controlled by a respective shut-off valve which is normally closed. A pump drains liquid from a stream of such liquid that is being fed under pressure to the machine tools for use as coolant/lubricant during machining, and feeds that liquid to the shut-off valves under an increased pressure. The shut-off valves are opened automatically one at a time in a predetermined sequence.

Abstract: An industrial washing machine for washing each of a continuous flow of production components in turn has a group of jets mounted in a respective manifold casing at each of one or more washing stations. Each manifold casing is hinged to fixed structure and is held in abutment with a locator stop by a toggle lever latch. Each jet is precisely located in position for use by the combination of the respective locator stop and hinge and can be swung from that position when the respective latch is released in order to facilitate access to the jets for cleaning and/or access to a production component which is supported at the respective washing station for cleaning so that, if such a production component should be displaced, relocation is facilitated. The jets in each manifold casing have a smaller diameter and longer bore than do the remaining jets in the washing section of the machine.
