Patent CA-2155339-A1 (CA)
Title: A method for measuring temperature, molecular composition or molecular densities in gases
Inventor: B TH LARS B
IPC: G01N9/24
Filed: 1994-02-03
Abstract: A measuring technique and method are provided to simultaneously determine the molecular density of several molecular species and the temperature within a closed process room in a melting or combustion process. In such processes in the industry, e.g. in metallurgic process industry, it is important to determine the temperature and the contents within the gas or flame without physically connect to or disturb the process. This has shown to raise large problems especially at high temperatures. The radio signal over a frequency band is measured on the outside of the process room through a window in the mantel covering as a function of frequency and registered on a computer as a radio spectrum. The system is calibrated by using a known signal transmitted through the process room. The spectral lines are identified by their frequency from a database. The temperature is determined from several lines of the same molecular specie and the molecular densities are determined from the intensities of the lines. The method is suitable to determine vibrational and rotational excitation of molecular species in the radio wavelength range of 500 m et 30 µm. The densities of molecular species and the temperature can be imaged in three dimensions inside the process room or exhaust channel if interferometers are used for simultaneous two dimensional imaging from several azimuth directions.

Title: Pesticide spray system for barns and the like
Inventor: OLDHAM MICHAEL J
IPC: A01M1/24
Filed: 1995-08-31
Abstract: A system for thoroughly spraying the interior of barn-like buildings with a pesticide. A truck carries a tank of liquid pesticide, a hose on a reel and a pump for pumping pesticide into the hose.  A cart including a tube having a first end for connection to the hose and a second end carrying one or more spray heads is placed at the far end of a building with the hose extending the length of the building and out a door to the truck.  The tube is mounted on at least two wheels, with a sled member supporting the end of the tube adjacent to the hose connection.  The spray heads produce a pattern in approximately a vertical plane perpendicular to the length of the tube and hose. As the hose is reeled up, the cart is pulled across the floor of the building, with the fan-like spray pattern fully treating the building interior.

Title: Method and apparatus for the deacidification of library materials
Inventor: LEINER LEE H
IPC: D21H25/00
Filed: 1994-08-10
Abstract: A method and apparatus for deacidification of cellulosic materi-als such as the pages of books, mag-azines, newspapers, documents and the like are provided which ensure that substantially the entirety of each page is treated. The method in-cludes placing the materials within a carrier (64) such that the pages are free for exposure to the treating medium. The carrier (64) is sub-merged in a vat (12) preferably con-taining a dispersion of treating mate-rial including particles of an alkaline metal oxide, hydroxide or salt. The vat (12) includes a support frame (51) which supports the carrier (64) and is slidably mounted on the vat (12) such that the carrier (64) and materials it holds may reciprocate in a generally horizontal direction. The reciprocation of the support frame (51) causes the pages of a book (72), for example, to fan out, and the treating material in the medium thus comes into contact with each page of the book, magazine or other doc-ument. After reciprocating the support frame (51) at a preselected speed and stroke length for a preselected length of time such that each page of the book is treated, preferably in its entirety, the carrier (64) is removed from the bath and transferred to a dryer (140). The dryer (140) includes a flexible meshed webbing (142) which is loosely draped over a series of support rods (144) mounted on a frame. The cellulosic materials are placed on the meshed webbing (142) and preheated air is passed through the dryer (140) to evaporate any excess residual treating medium.

Abstract: A radiation shield (5) includes an aper-ture (15) connected to an edge of the shield by a slit (20), which is held closed by a re-leasable flap (25). Instrumentation can be in-serted through the aperture to contact a patient over which the shield (5) is draped. By re-leasing the flap (25) and thereby opening the aperture (15) toward the edge of the shield, the shield (5) can be removed from the patient without removing the instrumentation inserted through the aperture (15). A secondary shield (37) is releasably secured over the aperture (15), affording further protection.  Because the shield is placed within the septic field dur-ing use, the shield includes a sterilizable outer covering (155).
