Patent number: 5753819Abstract: A pressure sensor including a housing having an interior surface forming a cavity, and a fill passageway communicating with the cavity. The fill passageway has opposite ends defining an axis extending between the ends, and one of ends defines a fill port spaced from the cavity. A pressure transducer is mounted on said interior surface. The pressure sensor also includes a sealing member moveable across the fill port in a direction transverse to the axis between a first position allowing fluid flow through the fill passageway and a second position closing the fill passageway such that the fluid is sheared off at the fill port to seal said cavity. Preferably, the fluid pressure within the cavity before sealing is substantially equal to the fluid pressure within the cavity after sealing.Type: GrantFiled: September 18, 1996Date of Patent: May 19, 1998Assignee: SSI Technologies, Inc.Inventors: Paul B. Rozgo, Robert C. Cooney, Michael F. Mattes, Jeffrey A. Kuberka, William J. Day, James D. Seefeldt

Patent number: 5695285Abstract: A temperature sensor assembly for measuring ambient temperature and including a housing defining an enclosure. A temperature sensor is mounted within the enclosure. The housing includes a brass cap and a liner for conducting heat from the brass cap to the temperature sensor. The temperature sensor is mounted on the brass liner and is electrically insulated from the brass liner by a thermally conductive material.Type: GrantFiled: August 7, 1996Date of Patent: December 9, 1997Assignee: SSI Technologies, Inc.Inventors: Jeffrey A. Kuberka, Michael F. Mattes, James D. Seefeldt, William J. Day

Patent number: 4700133Abstract: A variable reluctance magnetic speed sensor senses the speed of a rotating gear (12). A ferrous outer cylindrical shell (22) extends axially and has a magnet (14) at one axial end and a coil (16) at the other axial end. An inner pole piece (4) in the coil (16) directs magnetic flux across a gap to the gear teeth (10), which flux is returned by the outer pole piece shell (22) to the magnet (14). Particular pole piece gap spacings are disclosed together with various pole piece constructions.Type: GrantFiled: February 28, 1986Date of Patent: October 13, 1987Assignee: SSI Technologies, Inc.Inventor: William J. Day

Patent number: 4598691Abstract: A gas oven having a broil burner recessed up into a chamber above the ceiling to provide more usable space in the oven cavity. A partition closely above or extending from the sides of the burner forms an upper chamber duct which extends from an exhaust flue at the rear to a passageway to the cavity at the front of the chamber. The products of combustion from the burner flow forwardly in lateral troughs to the passageway where they mix with other cavity vapors and then rearwardly in the duct to the exhaust flue. The duct functions to reduce the body temperature of the burner to prevent flashback and also enhances stack action.Type: GrantFiled: April 1, 1985Date of Patent: July 8, 1986Assignee: Raytheon CompanyInventors: Edward J. Herrelko, James E. Hurley, William J. Day

Patent number: 4527049Abstract: A microprocessor controlled electric range having a solid state switch selectively associated with each surface heating element and a solid state switch in series and common to the circuits of each of the selectively associated switches. Each of the switches is controlled by a microprocessor and, if one of the selectively associated switches fails to a short circuit, the subsequent energization of all heating elements is disabled.Type: GrantFiled: February 9, 1984Date of Patent: July 2, 1985Assignee: Raytheon CompanyInventors: Calvin J. Thomas, William J. Day

Patent number: 4431889Abstract: A combination microwave and convection oven in which a gas burner positioned outside the oven provides heated combustion products which are drawn from the burner area along with vapor from an outlet of the oven by a blower system and the combined output of the blower system is blown into the oven through an oven inlet region in the oven wall. Both the oven outlets and the oven inlet are formed of holes substantially less than one-half wavelength in diameter. A predetermined portion of the blower output system is blown through an exhaust vent thereby creating slight negative pressures in the oven and in the burner plenum to accurately control the air flow through the burner.Type: GrantFiled: July 14, 1983Date of Patent: February 14, 1984Assignee: Raytheon CompanyInventors: Domenick Saponara, William J. Day

Patent number: 4430541Abstract: A combination microwave gas convection oven having a tubular burner operating in an induced draft environment. A blower system draws air from a combustion chamber forcing it into the heating cavity. The slight pressure created in the combustion chamber draws in air from the heating cavity through perforations communicating therebetween completing the convection recirculation. The negative pressure in the combustion chamber also causes secondary combustion air to be drawn up along the sides of the burner which is positioned adjacent to an aperture in the floor of the combustion chamber. A plurality of top ports in the burner provides low port loading. The structure provides good flame characteristics with low noise of combustion.Type: GrantFiled: December 6, 1982Date of Patent: February 7, 1984Assignee: Raytheon CompanyInventor: William J. Day, Jr.

Patent number: 4392038Abstract: A microwave convection oven in which a gas burner positioned outside the oven cavity has its combustion products circulated through the oven through screens for preventing escape of the microwave energy from the oven cavity with the burner being of the multi-ported type providing high burner density and having secondary air closely adjacent all portions of the burner to reduce its incondescent flame length while permitting the burner to be positioned in a region between the screened vapor outlet region the oven and the inlet of a blower system for mixing the output of the burner with the vapor drawn from the oven thus the temperature of the vapor outlet region is maintained below that at which ionization of the vapor being drawn from the oven might produce leakage of microwave energy through the screen.Type: GrantFiled: November 10, 1980Date of Patent: July 5, 1983Assignee: Raytheon CompanyInventors: William J. Day, Bernard J. Weiss

Patent number: 4373504Abstract: A convection oven in which vapor is circulated through the oven by a pair of counter rotating blowers positioned in the rear of the oven which draw vapor from the oven along with combustion products from a multi-section ribbon burner which has a secondary air passage between the sections and which is positioned below the oven rear wall vapor outlet region and blow the combined vapor and combustion products into the oven adjacent the top surface. The blowers generate slight negative pressure in the combustion plenum by blowing a small portion of the output of the blowers out an output vent to control the amounts of primary and secondary air supplied to the burner system.Type: GrantFiled: December 22, 1980Date of Patent: February 15, 1983Assignee: Raytheon CompanyInventor: William J. Day

Patent number: 4331124Abstract: A gas-fueled oven which is capable of safely assuming high temperatures such as occur during pyrolytic self-clean cycles and which employs a single multi-purpose fan for directing cool air flows over wall surfaces, for providing aspiration and temperature dilution of hot flue products, and for providing combustion air for a power broiler burner.Type: GrantFiled: July 2, 1979Date of Patent: May 25, 1982Assignee: Raytheon CompanyInventors: Harry W. Seidel, William J. Day, Jr.
