Patent CA-1324688-C (CA)
Title: Detector for radon
Inventor: YODER ROBERT C
IPC: G01T1/178
Filed: 1989-06-06
Granted: 1993-11-23
Abstract: ABSTRACT OF THE DISCLOSURE            A detector member having the property of forming damage tracks along the paths traversed by impinging alpha particles is provided with at least two opposing detection surfaces exposed on respective opposite sides of the detector member.  The opposing detection surfaces enable the detector member to form damage tracks by alpha particles impinging either of the detection surfaces which are simultaneously exposed to irradiation. Conventional cellulosic film such as cellulose nitrate can be employed with both sides of the film serving as detection surfaces.The dual-surfaced film can be framed and packaged in a compact configuration convenient to use in homes or offices.  The damage tracks from both of the irradiated surfaces can be simultaneously counted using preferred spark counting techniques.

Abstract: Abstract Of The Disclosure Variations in the relative humidity of the air present within a housing of a scale (10) particularly a high accuracy scale utilizing a capacitive transducer (16) mounted at the interior of the housing, are controlled by a combination of (i) a mechanical partial seal (34) of the housing which resists a flow of moisture (by diffusion and air flow) through the seal, and (ii) a supply (42) of a desiccant located within the housing which both absorbs and desorbs moisture from the air held within the housing.  The partial seal (34) is preferably located at an opening (18) in the housing for a shaft (20) mounting a weighing pan (22) external to the housing.  For low motion, a face seal of a few mils provides the appropriate flow resistance.  For high motion or low capacity scales, the partial seal (34) is a radial seal formed by the shaft and a surrounding sleeve mounted with a small annular clearance is used.  The desiccant (42) is preferably silica gel.  The values for the flow resistance and desiccant supply for a given interior volume produce a very slow change in the relative humidity in the housing over time, typically several years.  In use, the relative humidity within the housing varies within ?5% of a steady state value despite much larger variations in the temperature and humidity of the ambient air surrounding the housing.

Abstract: Abstract of the Disclosure An improved curb section of a predetermined length sub-divided into modules by transverse grooves which give the appearance of shorter blocks and provide for fracturing the curb  section at  those locations.          Each module of the curb section includes a rearward fastening projection having a vertical bore for passing a nail to engage the curb section to pavement or other base.    Such linear mold sections  are all  that are required when a curve is dictated.  The mold sections are sub-divided into the modules to form the curve.   A method of forming the curb section is provided which includes  an  open  frame  moving vertically  against  a platform  and  mold  shoes  for  pressing  down  on  the concrete when poured in the mold frame, including plugs for forming the tops of the fastening projections.  The plugs are removed after the mold frame is lifted,  and then the shoes are removed to leave the  formed curb sections on the bottom wall.

Title: Method and apparatus for setting-up rolling mill roll  gaps
Inventor: TSUGENO MASASHI
IPC: B21B37/58
Filed: 1989-09-19
Granted: 1993-09-21
Abstract: ABSTRACT In setting roll gaps of a rolling mill having a stands arranged in tandem, a resistance to deformation of a workpiece in each of the stands is calculated on the basis of a cumulative strain in each stand with strain of the workpiece which is in an entrance side of the mill and  in  a  soaked  state  being  0.    The  resistance  to deformation of the soaked workpiece is obtained in each stand,  so  that  the  accuracy  of  estimation  of  the resistance to deformation is improved and thus a precise roll gap setting becomes possible,  resulting in that a product thickness is made coincident with an objective thickness at high accuracy.

Abstract: There is disclosed a method for making a self-supporting ceramic composite article having a porous core bearing a dense surface layer formed integrally with said core. A preform comprises a filler material and parent metal distributed therethrough, wherein the volume percent of parent metal is sufficient to form a volume of oxidation reaction product exceeding the total volume available within said preform. The parent metal is molted and reacted with an oxidant to form an oxidation reaction product filling the spatial volume and leaving voids. The reaction is continued to further transport molten parent metal through the oxidation reaction product to at least one surface of the preform to form oxidation reaction product on said surface substantially free of voids thereby forming a relatively dense surface layer.

Granted: 1994-08-02
Abstract: The telephone includes a touch sensor which may be attached on a handset.  When the telephone receives a call meant therefor, the telephone alerts the user to the call by outputting a ringing tone through a speaker.          In response to the call, the telephone also transmits a signaling tone to a base station which may be connected to the telephone over a radio channel and to a public switching telephone network.  If the user touches on the touch sensor in response to the ringing tone, the telephone stops the signaling tone and thus informs the base station that the user has responded to the call.

Granted: 1995-02-14
Abstract: An optical communication system in which transmission of information with a pumping light beam acting as the carrier, in addition to transmission of information with a signal light beam, is made possible is disclosed.  This optical communication system includes an optical fiber amplifier adapted to amplify a signal light beam by having the signal light beam and a pumping light beam propagated through its rare-earth-doped fiber doped with a rare earth element and a modulating circuit for modulating the pumping light beam with a high-frequency modulating signal having a period shorter than the life span of fluorescence resulting from an excited state.  In the case where the signal light beam and the pumping light beam are propagated in the same direction through the rare-earth-doped fiber, the transmission of information with the pumping light beam acting as the carrier can constitute a transmission of supervisory signal for an optical repeater, and in the case where the signal light beam and the pumping light beam are propagated in the directions opposite to each other through the rare-earth-doped fiber, a two-way transmission can be achieved by the transmission of information with the signal light beam and the transmission of information with the pumping light beam.

Abstract: An air intake system for a snowmobile which comprises an internal combustion engine having an induction system.  A body is provided which cooperates in defining an engine compartment wherein the engine and induction system are contained.  This body has an opening for inducting air from the atmosphere and is in communication with a passageway which defines an air flow path from the opening to the induction system so that air flows from the opening to the induction system without accumulating in the engine compartment.  A filter element is positioned between the opening and the induction system across the air flow path such that the air flows in a generally upward direction through the filter element.  The filter element not only prevents snow and ice from being sucked into the induction system but also prevents these elements from clogging the filter, while still allowing for adequate air flow to the induction system.
