Abstract: Application for Letters Patent of MILTON HALSTED and TIM M. UYEDA for SHOWER SPRAY APPARATUS     ABSTRACT OF THE DISCLOSURE     The shower spray apparatus has a hollow housing with three spray exit openings in a common face, two for normal spray and the third for pulsating spray.  Incoming pressurized water is fed into a diverter which includes a slide valve adjustable to proportion the flow of water along either of two paths exclusively, or in a continuous variable range between the two paths.  The first path of fluid flow from the slide valve terminates in the two normal spray exit openings, while water flowing along the second flow path drives a turbine and exits via openings in the pulsating outlet.  The rotating turbine includes a mask which sequentially covers and uncovers the spray outlet to provide the pulsating output.  A knob on the spray apparatus housing is adjustably rotatable to operate a slide valve throughout a full range of adjustment, providing either all normal spray, all pulsating spray or any ratio therebetween.  Adjustment of the slide valve adjusts the normal spray outlet to compensate for the change in water supply thereto and thereby provide a substantially uniform spray pattern and spray particle size.

Abstract: ABSTRACT OF THE DISCLOSURE             Reduced decarburization production of steel is achieved by the process provided herein. It includes the step of preliminarily cleaning and roughing the exterior of a steel workpiece, and then applying an adherent removable protective surface coating of metal material onto the exterior of a steel workpiece to be heated, e.g., by providing a metallized, e.g., aluminized, adherent removable protection surface coating on that cleaned surface of the steel workpiece, Then the process involves carrying out such heating of the hereby protected steel workpiece, such heating including at least one hot working step, e.g., by heating for hot-working and/or annealing, e.g., of the semi-finished billet. Then the resultant metal material coating is removed. Novel metallized coating products are thereby fabricated. Thus, by this invention, an efficient and economical process for heating tool steel substantially protected against attendent decarburization during such heating is provided. This avoids the problems of conventional heating techniques.

Abstract: TRAY WASHER APPARATUS              Abstract of the Disclosure A machine for washing articles which are of greater height than width dimension when supported by an article receiving rack includes a cabinet of generally rectangular horizontal cross-section capable of accommodating the horizontal dimensions of the rack.  The cabinet defines a washing chamber and a front access opening of sufficient height to accommodate lateral movement of a rack containing upright articles into the washing chamber.  A lower door is pivotally mounted on the cabinet adjacent to the lower edge of the access opening for movement from a vertical closed position to a horizontal open position.  The lower door includes a rack supporting surface and is dimensioned to correspond in size to the rectangular horizontal cross-section of the cabinet.  An upper door is mounted for vertical movement from a lower position covering the remaining upper portion of the access opening to an upper position uncovering the upper portion of the access opening.  A mechanical linkage interconnects the upper and lower doors and coordinates opening and closing movement of the doors.

Abstract: ABSTRACT OF THE DISCLOSURE       A thermal energy converting assembly including a support housing rotatably supporting a central hub with a plurality of temperature sensitive metal alloy strips extend-ing radially from the hub for coacting with a cam which sinus-oidally strains the strips during one phase and allows the unstraining of the strops during a second phase.  The strips are made of a material which undergoes a thermoelastic, marten-sitic phase transformation whereby in a relatively cold condition it takes less energy to strain the strips than is produced from the strips as they become unstrained when subsequently subjected to a hotter condition  In the first embodiment the strips are strained by torsional twisting as a result of lever arm attached to the ends of the strips and reacting with the cam whereas in the second embodiment the strips are strained by bending as push rods are associated with the distal ends of the strips and have rollers thereon for coacting with the cam.
