Abstract: Volleyball practice apparatus especially useful in training players in spiking the ball includes a lightweight, flexible support harness closely engaging and confining a volleyball, and a pair of flexible, elastically extensible lines having one end attached to the harness and their other end attached one to each of a pair of upwardly extending supports adjustably mounted on a lightweight structural frame adapted to be attached to the volleyball net to support the volleyball above and to one side of the net in position for spiking. The elastically extensible support lines permit the ball to be projected down and across the net in substantially the same manner as in spiking a free ball. The extensible lines then return the ball upward and back across the net into position to be spiked again.

Abstract: Air removal is completed and ascertained, in steam sterilization systems which use steam flow through a sterilizing chamber to facilitate air removal, by methods which enable steam-table values for a dependent variable relationship of pressure and temperature, as exhibited by confined saturated steam, to be utilized under steam flow conditions.Apparatus for controlling and measuring chamber conditions are provided so that such established steam-table values for confined steam can be readily and reliably used to establish and ascertain complete air removal while steam is flowing through the chamber.In a representative embodiment, chamber pressure is held substantially constant while the remaining variable chamber temperature is measured. Venting of chamber atmosphere is continuous during such control of chamber pressure with chamber temperature being measured until a value is reached corresponding to the steam-table value at the level of the chamber pressure being held.

Abstract: A nozzle and associated apparatus for controlling the thickness of liquid coating on continuous webs which produces a thin jet of fluid for impingement across the width of moving web having a liquid coating thereon, the fluid in the portions of the jet on either side of the center of the nozzle having components of motion toward the edges of the web. One form of nozzle structure for achieving such lateral movement of the fluid issuing from the nozzle has a centrally positioned fluid inlet port to an inner plenum chamber, the port having a cross sectional area at least several times the cross sectional area of the nozzle orifice. Another form of nozzle structure for accomplishing this purpose involves baffle means in the path of the fluid flowing through the nozzle which changes the direction of flow of the fluid so as to give the fluid on either side of the center of the nozzle a component of motion toward the edges of the nozzle.

Abstract: A single reflective afocal optical module collects and concentrates solar energy onto a receiving surface extending substantially parallel to the focal axis of the optical system and to the central axis of the module. The reflective surface of the collector is shaped to reflect incoming energy and distribute it uniformly over the full surface of the receiver, with the reflective surface preferably consisting of a plurality of discrete reflective surface portions each distributing its portion of reflected energy over the full receiver surface so that the energy portions from the respective reflective surface portions are superimposed on one another on the receiver. The reflector and receiver are housed in a sealed enclosure having a transparent window for admitting incoming energy, and heat extracting means removes excess heat from the enclosure.

Abstract: A method of and system for controlling the oil concentration in and the stability of an oil-in-water emulsion used as a coolant-lubricant in a metalworking operation in which a portion of the emulsion is circulated through a sensor to monitor its density and to generate a signal relating the density to the oil concentration. The signal is employed to control addition of oil to the emulsion to thereby control the concentration within close limits. Sensing means also monitors the stability of the circulated emulsion, and emulsifier is added, as required, either to the oil to be added or directly to the emulsion to thereby control both the oil concentration in and the stability of the emulsion.

Abstract: Method and apparatus in which moving metal strip is treated in a treating solution in an elongated tank having a granite bottom sloping upwardly on each side of the longitudinal center line of the tank and ultrasonic energy is directed downwardly through the moving metal strip to be reflected back and forth between the sloping granite bottom and the surface of the treating solution in a path that extends across the width of the tank and repeatedly intersects the moving metal strip. The minimum number of ultrasonic generating units are possible in an arrangement in which the ultrasonic generating units extend longitudinally of the tank along a line above a marginal portion of the moving metal strip. The sonic generators can be supported in liquid-containing receptacles which extend below the liquid level of the treating solution in the tank. The liquid-holding receptacles can be supported on cover members which extend across the tank and enclose the top of the tank.

Abstract: An improved dishwashing system includes operating methods and apparatus for water and energy conservation and elimination of spot-reducing chemicals in the rinse water. Return water from the rinse cycle is stored in insulated tanks and rinse water flowing to the dishwasher absorbs heat from the return water to thereby conserve the heat energy of the return water while simultaneously cooling the return water to a selected temperature in preparing a feed solution for membrane separation. A controlled quantity of make-up water is added to the feed solution which is raised to a selected pressure to provide for reverse osmosis purification and deionization. The reverse osmosis effluent is accumulated and, when needed, boosted in pressure to a desired operational dishwasher pressure, and heated to sanitizing level so as to achieve desired bacterial count levels during rinse cycles. Rinsing with the purified and deionized water results in film-free and spot-free dishes after drying.

Abstract: An electrolytic process and a cathode structure for use in the process for treatment of an elongated strip of metal as the strip is passed between an anode immersed in an acidic anolyte solution and a cathode immersed in a basic catholyte solution separated from the anolyte solution by an ion-permeable membrane. The cathode structure includes means for directing a flow of the catholyte solution through a chamber enclosing a negatively-charged cathode plate to cool the structure and to remove hydrogen gas which is evolved on the active cathode surface to increase the efficiency of the electrolytic process.

Abstract: A device for sampling heats of molten metal includes a mold cavity which has an inlet which may be in the form of a tube projecting outwardly therefrom with the open end of the tube being closed and sealed prior to the sampling step by a metallic cap which will melt in the molten metal heat. The sealed end of the tube is enclosed within a diffusion chamber having an inlet closed with a cap which will be melted or vaporized by the metal heat and which normally retains a quantity of a suitable oxygen-fixing agent such as aluminum or titanium, for example, within the chamber. Molten metal entering the diffusion chamber immediately melts the fixing agent which is quickly dissolved by and thoroughly diffused through the molten metal in the chamber before the metal cap on the end of the tube melts to permit the molten metal with the oxygen-fixing agent diffused therethrough to flow into the sample-forming mold cavity.

Abstract: Metal in sheet or strip form is electroplated in a continuous or semi-continuous process in which a running length of the metal is passed through a bath of electrolyte solution having an anode structure supported therein adjacent the surface or surfaces to be electroplated. The structure of the anode enables use of the apparatus to electroplate strips of various widths without encountering adverse side effects or streaking and enables substantial economies in electrical current. The anode structure is particularly useful in the production of strip steel having a zinc coating on one side only.
