Patent CA-2023754-C (CA)
Title: Building block
Inventor: BERGERON DENIS
IPC: E04B2/02
Filed: 1990-08-22
Granted: 1994-10-04
Abstract: The building block comprises spaced apart outer and inner concrete walls and a pair of tie members for interconnecting these two walls.  Each tie member has a first T-shaped end embedded into the concrete of the outer wall.  A solid and cubic body is made of wood and is fastened to a second end of each tie member.  For that purpose, each body has a hole therein, and the second end of each tie member is forked to define first and second branches embracing a portion of the body and having respective free ends bent to penetrate the hole through its two ends, respectively.  The cubic body defines edges having a length equal to the thickness of the inner wall, and it is embedded in the concrete of this inner wall with a surface thereof exposed on the two sides of the latter wall.   Nailing and/or screwing through the cubic body is therefore enabled from the outer side of the inner wall with the nails and/or screws extending in the space between the outer and inner walls.  Also, a wall constructed with building blocks in accordance with the invention comprises an inner, empty space that can be easily filled with loose fill insulation.

Title: Coaxial dual primary heat exchanger
Inventor: WILSON JAMES C JR
IPC: F28D7/10
Filed: 1991-05-13
Granted: 1994-05-10
Abstract: ABSTRACT OF THE DISCLOSURE   Basically the present invention in it's most simple form or embodiment is directed to a heat exchanger which provides for at least two heat exchange surfaces and which has the combustion of the fuel, which generates the heat, take place within the heat exchanger rather than the heat of combustion being introduced into the exchanger from an external combustion chamber and wherein the flame is directed into an opening of a truncated cone which cone has a shape approximating the shape of the flame and wherein the tips or ends of the flame "play" on an arcuate surface which is in thermal energy transfer communication with fluid to be heated which is at the unheated or ambient temperature. Additionally, note that the fluid, air in the case of a hot air system, is introduced into the passages where heat exchange will take place, and directed toward the hottest region of the combustion chamber. This is, the coldest air comes into thermal contact with the hottest region providing for maximum heat exchange. The flame is introduced into the combustion chamber in a direction which is essentially parallel to the axis of the cylindrical device. As a consequence the flame does not impinge onto any substantially flat or planar surface. Because of the nature of the construction of the nozzle etc., the flame forms into a cone configuration allowing thorough mixture with the combustion air and thus providing for complete and efficient combustion. The structural details and the pressures that are developed within the combustion chamber and the combustion region, cause the flame to "play along the conically configured walls of the truncated portion defining the combustion chamber and to impinge onto the curved/arcuate surface which conductively transfers heat to the air or fluid entering the first heat exchange volume or space. The heat of the combustion gases is given up to the fluid in basically five (5) heat exchange volumes of the device.

Title: Multichannel device for measurement of weak spatially and temporally varying magnetic fields
Inventor: AHONEN ANTTI ILMARI
IPC: A61B5/05
Filed: 1991-12-10
Granted: 2001-05-08
Abstract: The invention concerns a superconducting device used to measure temporally and spatially varying magnetic fields generated by sources inside the object to be investigated. The invention consists of a body divided into separate and easily interchangeable self-supporting modules, interconnected by connectors. The superconducting magnetometer or gradiometer elements (12) have been attached by means of connectors (11) to the cross-connection/support element (6); this element (6) is attached to a connecting element (4) by means of connectors as well. The connecting element (4) contains also the electric components (5) necessary for connecting the SQUIDs to the room temperature electronics (14).  The connecting element (4) is attached to the neck plug (3), comprising a stiff thermal isolation preventing convection and a ribbon cable made of parallel twisted pairs.      The element (3) is self-supporting and it farms an integral part of the magnetometer support structure. The cables in the neck plug have been made out of wires having a relatively high resistance in order to minimize the heat leak between the room temperature and the cryogenic environment of the magnetometers; the excess noise caused by the resistive leads has been compensated, for example by increasing the SQUID gain using positive feedback.

Abstract: A fracturing tool for connecting rods has a first and second body prepared from material with a grain direction, each body having a semi-cylindrical protuberance with an axis substantially parallel with the grain of the material.  The two protuberances together define a substantially cylindrical mandrel which can be placed within the large bore of a connecting rod which is to be cracked.  The bodies are mounted so that one of them is slidable toward and away from the other in a direction perpendicular to the axis of the mandrel.  The method of making the tool includes mounting the bodies on a rotary table having an axis of rotation coaxial with that of the mandrel.  The rotary table rotates while a grinding wheel finish grinds the mandrel surface.
