Title: System for controlling mass flow rates of two gases
Inventor: SMITH DAVID H
IPC: G05D11/13
Filed: 1987-08-14
Abstract: A control system for internal combustion engines, including a first conduit for the flow of intake air, and a second conduit for the flow of natural gas to be mixed with the air for combustion. The flow of the air is variable over a range of mass flow rates during operation of the engine and an air mass sensor is positioned to sense the mass flow rate in the first conduit and generate a first flow rate signal indicating the mass flow rate. A natural gas mass sensor is positioned to sense the mass flow rate of the gas in the second conduit and to generate a second flow rate signal indicating the mass flow rate of the natural gas. The first and second flow rate signals are compared in an electronic controller that generates a control signal if the first and second flow rates vary from a predetermined ratio. The ratio is selected to provide a substantially stoichiometric ratio of air and natural gas. A valve is provided to adjustably control the flow rate of the natural gas in response to the control signal to maintain the preselected ratio. A sensor and shutoff valve are also provided for terminating the flow of the natural gas when its pressure falls below a predetermined pressure, allowing immediate flow of gasoline to the engine, thus assuring smooth, continued operation of the vehicle. A throttle body has a natural gas distribution ring in the throat of the body and provides a curtain flow of gas.

Title: Improved mechanical end face seal
Inventor: WASSER JAMES R
IPC: F16J15/40
Filed: 1993-06-03
Abstract: A double, back to back oriented mechanical end face seal (10) for use in sealing toxic or corrosive fluids having an intermediate buffer fluid chamber (26) into which a relatively inert gas, such as nitrogen, is provided for use as a buffer fluid. The nitrogen gas is maintained at a pressure which exceeds the process fluid pressure by at least 10 p.s.i. and, in a preferred embodiment, spiral pumping grooves (44,74) in the mating rings (40,60) of each of the seals (22,24) are shaped and dimensioned to pump the nitrogen buffer gas through the first seal (22) from the intermediate chamber (26) into the process fluid chamber (12) and through the second seal (24) from the intermediate chamber (26) into the environment external to the housing (12) and sealing area, thereby avoiding the escape of the process fluid into the intermediate buffer chamber (26) and to the atmosphere. Contamination of the process fluid by the buffer gas may be tolerated. The buffer gas may be any relatively inert gas, a gas which is non-hazardous to the environment and also is compatible with the process fluid used; appropriate examples are nitrogen, carbon dioxide, air or one of the noble gases. The seal (10) can be used to seal a process fluid which is either a liquid or a gas. <IMAGE>

Title: Apparatus for a particular food product
Inventor: HANSEN EJNER BJORN
IPC: A47J36/38
Filed: 1998-05-08
Abstract: A chamber serving for a heat treatment of a particular food product, which for example can be pre-processed potato pieces which are to be prepared as French fried potatoes, and therefore have a content of evaporable substances, such as fat. In the chamber is a grid for, during operation, carrying the product, and one or more quartz lamps for generating heat for the process. The chamber is furthermore fitted with an exhaust channel which via a filter device connects the chamber to the open. Above the grid is placed a cabinet which is open at the bottom, for mounting the quartz lamps. The cabinet is via an inlet duct connected to the open. In the inlet duct is placed a ventilator for sending an air flow into the cabinet via the inlet duct. The air acts as a shield which keeps for example fat vapors at a distance so that they cannot come into contact with the quartz lamps and disintegrate in the high temperature of these. Thereby, it is prevented that unhealthy and malodorous substances are produced during the process. The air shield furthermore cools the quartz lamps, which thereby will attain a long life.

Title: Method and apparatus for automatically identifying a program including a sound signal
Inventor: FARDEAU MICHEL
IPC: H04B17/00
Filed: 1992-09-22
Granted: 1996-04-10
Abstract: A method and apparatus for automatically identifying a program broadcast by a radio station or by a television channel, or recorded on a medium, by adding an inaudible encoded message to the sound signal of the program, the message identifying the broadcasting channel or station, the program, and/or the exact date. In one embodiment the sound signal is transmitted via an analog-to-digital converter to a data processor enabling frequency components to be split up, enabling the energy in some of the frequency components to be altered in a predetermined manner to form an encoded identification message, and with the output from the data processor being connected via a digital-to-analog converter to an audio output for broadcasting or recording the sound signal. In another embodiment, an analog bandpass filter is employed to separate a band of frequencies from the sound signal so that energy in the separated band may be thus altered to encode the sound signal. The invention is particularly applicable to measuring the audiences of programs that are broadcast by radio or television, or that are recorded.
