Abstract: An intake relief valve comprises a bronze sectional gate positioned within the valve chamber adjacent to an outlet section of the valve. A quick attachment coupler of the valve connects the outlet section typically to a pumper fire truck, and a hose from a hydrant or draft source connects to an opposite inlet section of the valve. When the valve is closed and the hose is disconnected from the valve with the valve connected to the pumper fire truck, there is no water remaining in the valve chamber. Any residual water is released by a pit drainage outlet on the bottom wall of the valve. Not having water stored in the valve eliminates corrosion problems within the valve, when the valve is connected to the pumper fire truck.

Abstract: A discrepancy in the model setting between controllers is definitely detected. When it is judged at S4 that the setting is a split vat model, the procedure then goes to S5 for determining the cooking menu at the right oil vat, S6 for processing data to be transmitted to a burner controller, and S7 for processing data received from the burner controller. When it is judged at S8 that the setting of the burner controller is a full vat model because the temperature of a thermistor at the right oil vat received from the burner controller is an FFFFH level (equivalent to 3609° C.), the discrepancy in the setting is displayed for notification at S9. Then, the burner controller is instructed at S10 for extinction.

Abstract: A fryer having an overheat protecting means for carrying out an operation test properly, thus improving the utility of the fryer. When it is determined that a high limit test is being performed a burner controller examines whether or not the temperature measured by a thermistor exceeds a preset level for the test determined by a fryer controller. If not, the combustion is continued and the burner controller repeats the test for overheating protection. When the temperature exceeds the preset level the burner controller tries to keep the temperature between the preset level and the preset level plus alpha. This is followed by turning off a high limitswitch and notifying the fryer controller for displaying a high limit abnormality.

Abstract: A control valve for a vessel gas water heater includes a single governor for controlling a wider range of the flow of gas from pilot supply to main supply. Once an ignition knob 1 is pressed and turned to open the magnetic valve V1 and ignite the pilot burner PB, the magnetic valve V1 is maintained open by the electromotive force of a thermocouple TC heated by a pilot flame c. When the ignition knob 1 is released from being pressed, and turned further to open the plunger valve V3, the boiler is shifted to the standby state for enabling the supply of gas to the main burner MB. Meanwhile, a sensor rod B is mounted in a reservoir A for contracting and expanding depending on the temperature of the hot water in the reservoir A to open and close the snap valve V5, thus controlling the combustion and its cancellation in the main burner MB. Accordingly, the temperature of the hot water in the reservoir A can automatically be controlled in the vessel gas water heater.

Abstract: A piezoelectric switch comprising an end surface which when pressure is applied, causes a piezoelectric element to switch and generate an electrical signal. In addition, the piezoelectric element provides audible feedback to an operator activating the switch. The piezoelectric switch comprises a plastic housing having the piezoelectric element adhesively attached to an inside surface of a top portion of the housing. Two wires from the piezoelectric element connect to a printed circuit board which is placed adjacent to the piezoelectric element and wires from the printed circuit board extend through a cap for external connections. When the piezoelectric element switches, an output pulse having a predetermined pulse width is generated along with a signal which is fed back to trigger an oscillator connected to the piezoelectric element causing it to buzz, thereby providing audible feedback from the same piezoelectric element.

Abstract: To make coincide cutting centers of two end surfaces of raw wood with the axis of spindles of a veneer lathe, at least two axial corrections which are performed in a state in which the raw wood is held by centering spindles are required. Conventional apparatuses suffer from too complicated structures and enlargement of the cost because of the complicated structures. A correction operation of an axial direction of correction operations in the two axial directions is performed such that only a movable centering spindle is moved in a direction intersecting a direction in which holding arms are extended/contracted. Another correction operation in another axial direction is performed by extending/contracting the holding arms.
