Patent CA-1194693-A (CA)
Inventor: OWEN JOHN A
IPC: F27D99/00

Granted: 1985-10-08
Abstract: ABSTRACT There is provided a method and apparatus for counteracting the tendency for outside air to be drawn into a continuous heat treating furnace in which a feeder pan extends through the charge end opening.  A problem commonly encountered is that the hot gaseous atmosphere within the furnace tends to escape through the charge end opening above the feeder pan, while outside air tends to be drawn into the furnace below the feeder pan.  This invention provides a vacuum seal which includes air-withdrawing means located adjacently outside the opening and under the feeder pan, adapted to withdraw sufficient air to counter-balance the tendency for outside air to be drawn into the furnace below the feeder pan.

Abstract: METHOD AND APPARATUS FOR REMOTE INDICATION OF FAULTS IN COAXIAL CABLE R-F TRANSMISSION SYSTEMS     ABSTRACT OF THE DISCLOSURE  .    A method for locating faults or failures in R-F coaxial cable TV transmission facilities is shown and described.  A fault locator signal frequency is inserted into  a  cable  system,  and  low magnitude  signals  are emitted by means of a band pass filter and radiating element.   The  radiated R-F  is  detected to determine coaxial cable system operation.  Band pass filters and radiating  elements  are  located  at  each  point  to  be tested.     An apparatus for emitting a controlled narrow band of R-F energy which utilizes a band pass filter and a radiating element is also shown and described.     This is the disclosure of intentional, controlled, discriminate R-F radiation used for fault detection and a coupler-band pass filter to accomplish it.

Abstract: ABSTRACT:         "Method of manufacturing a semiconductor device by means of plasma etching."          A method of manufacturing a semiconductor device, in which a layer of silicon nitride (3) overlying a silicon oxide layer (4) present on a substrate (2) is etched by bring-ing it into contact with substantially only uncharged con-stituents of a plasma formed in a reactor to which a sub-sgantially oxygen-free gas or gas mixture is supplied.          According to the invention, 0.1 to 25% by volume of a halogen different from fluorine or of a compound containing a halogen different from fluorine are added to this gas or gas mixture which contains fluorine or a fluorine compound.          Thus, a high etching selectivity of silicon nitride with respect to silicon oxide is obtained, which moreover, does not vary during etching.

Abstract: Abstract To measure the heat transfer coefficient of a sample, an element with temperature sensitive optical properties  is placed  in contact or  implanted  in  the sample.  The element is heated or cooled.  The temper-ature difference between the element and the unheated sample and the rate of heating or cooling indicate the heat transfer coefficient of the sample.  In one embo-diment, the element is heated or cooled at a constant rate.  The heat transfer coefficient of the sample is then inversely related to the difference in temperature between  the element and  the unheated  sample. Alter-natively, the element may be heated or cooled at such a rate that the temperature difference between the element and the unheated sample remains substantially constant. The heat transfer coefficient of the sample then varies directly with the rate of heating or cooling.  The heat transfer coefficient of a sample is a measure of its composition and other physical properties.  The compo-sition of gasses, liquids, the presence of bubbles in a liquid, and fluid levels can be detected by the optical technique.  Pressure and flow rates of fluids can also be detected.  The  technique  can  be  used  also  to  more accurately measure the thermal conductivity and temper-ature of small objects with small heat capacities.
