Abstract: A low wash and rinse temperature (120° - 140° F) warewasher accomplishes the same general washing and rinsing effectiveness as a conventional high temperature (150° F minimum wash, 180° F minimum rinse) warewasher without loss of productivity resulting from time lost between completion of washing and commencement of rinsing a given load of ware, through use of independent, dedicated wash and rinse systems, the latter of which includes a holding tank which enables independent batching of a predetermined volume of rinse solution from properly-proportioned fresh water and sanitizing agent while washing a given load of ware. The sanitizing independently of the fresh water line, and is therefore unaffected by a great range of water line pressures and the mineral condition of the water.

Abstract: PASSIVE DOSING DISPENSER     Robert S. Dirksing ABSTRACT OF THE DISCLOSURE         A passive dosing dispenser for issuing, for example, a predetermined volume of a toilet tank additive solution into a toilet tank as the water is draining there-from while the toilet is flushing.  A preferred dispenser comprises a reservoir for containing a quantity of a toilet tank additive type product and in which reservoir a solid type product can be dissolved to form a product solution.          In operation, while the water in the toilet tank is receding from about the dispenser, a predetermined dose-volume of toilet tank water is vacuum-transferred into the reservoir through an inlet conduit, and a substantially equal dose-volume of the product solution is dispensed through a discharge standpipe.  The dispenser may further comprise an internal baffle to precipitate mixing and agitation inside the dispenser which promote dissolution.  The dispenser also provides an air-lock when immersed in a full toilet tank which air-lock isolates the product and product solution from toilet tank water which surrounds the dispenser during quiescent periods.  In a particularly preferred embodiment, a dispenser which further isolates the solid type product from the product solution during quiescent periods is provided.          Plural product co-dispensers which embody the present invention are also disclosed.

Abstract: COOLING ARRANGEMENT FOR A REFRIGERATOR           MACHINERY COMPARTMENT               ABSTRACT OF THE DISCLOSURE          A refrigerator has a machinery compartment at the bottom for housing a motor-compressor unit and a condenser and has an air inlet opening at the front thereof extending substantially across the width of the compartment.  The machinery compartment includes a forward section for receiving the condenser and a duct at the rear portion thereof for receiving the motor-compressor unit.  The duct has an air inlet at one end for receiving air from the forward section.  The condenser extends generally horizontally from one side wall of the compartment across a substantial portion of the forward section.  A drain pan is supported above the condenser for collecting water draining from the interior of the refrigerator.  The drain pan additionally functions as a baffle to cause air entering the forward section to flow effectively over the condenser.  A fan is positioned at the inlet of the duct and the motor-compressor unit is so positioned in the duct that the compressor portion thereof is positioned adjacent to the fan so that substantially all of the air discharged from the fan is directed onto the compressor portion, thereby maximizing the heat transferred from the compressor to the air flowing through the compartment.

Abstract: INMPROVED ELECTRICALMECHANICAL PRESSURE TRANSDUCER                     ABSTRACT OF THE DISCLOSURE      An improved ceramic capacitive pressure sensor adaptable for use in automobiles is disclosed.  The pressure sensor comprises a thin flexible diaphragm disc having a capacitor electrode deposited on it.  A thick cylindrical base sub-strate has a top surface with a second capacitor electrode deposited thereon and the diaphragm is bonded to the top surface of the base substrate by an annular glass ring such that the first and second electrodes are separated from each other and face each other directly across an air gap.  The diaphragm, the top surface of the base substrate and the annular glass ring form an internal cavity in which a reference vacuum is stored.  In response to pressure changes outside of this cavity, the diaphragm will flex and thereby change the capacitance created by the first and second electrodes.  At least one channel portion is provided in the base substrate top surface which opens into the cavity storing the reference vacuum.  This improves the electrical and mechanical characteristics of the pressure sensor.  The diaphragm electrode is substantially larger than the base electrode and extends substantially over all of the central portion of the diaphragm within the glass annular ring and in this manner the electrode acts as a shield against con-ductive elements which are exterior to the internal cavity and are adjacent to the thin diaphragm.
