Abstract: A water inlet device for an automatic clothes washer is provided which provides a flow of water against an interior surface of a wash basket and onto a clothes load within the basket through a wide range of inlet water pressures while preventing excessive splashing against the basket wall at high water pressures. The inlet device has a downwardly angled front wall which redirects the inlet water into the wash basket, and the wall has a varying downward angle along its length to provide the automatic pressure compensation. A central portion of the lip is angled downwardly toward the basket wall and the lateral edges are angled downwardly away from the basket wall such that at normal water pressures most of the inlet water is directed at the central portion, and thus toward the basket wall, and at higher pressures more water is directed toward the lateral edges which direct the excess water away from the basket wall and directly onto the clothes load.

Abstract: The invention provides an air operated film-handling or stabilizing device that can be used with most thin flexible films or webs, such as plastics, paper, thin metal, etc. The configuration of the device depends upon the shape of the sheet and, for example, is flat for flat sheets and ring-shaped for use in blown plastics film production to surround the blown bubble. The device provides two opposite orifices which discharge respective streams of air in opposite directions over respective surfaces which are parallel to the face of the film to be handled and/or stabilized. A third surface is disposed between the two orifices also parallel to the film face, but spaced further from it than the two first-mentioned faces, resulting in a zone of lower air pressure that urges the film toward the third surface, but without the possibility of touching it, or the other two surfaces, so that the film is held by the force in a stable location relative to the device.

Abstract: This invention, titled Paraboloidal Drinking Fountain Attachment, provides a novel means for redirecting a stream of water from a faucet into an arc convenient for drinking. The invention is for use with a movable faucet and, when provided with an extension, also can be used with a stationary faucet.

Abstract: This disclosure relates to a new apparatus and spray head for fluid dispersion for use in removing particulate matter from air. The spray head comprises a rigid spray plate bent to a predetermined configuration with two head side plates attached to said spray plate, and two spray side guide bars attached to said side plates.

Such a spray head apparatus would typically be located at the base of a scrubbing unit connect to a paint spray booth or the like, said scrubber containing baffles through which contaminated air is passed and cleaned prior to emitting the remaining particle-free air to the atmosphere.
