Patent CA-2009232-A1 (CA)
Inventor: BARTLETT MATTHEW
IPC: F28D1/047
Filed: 1990-02-02
Abstract: Abstract of the Disclosure A heat exchanger assembly comprises a pair of header members and a plurality of heat transfer tubes passing between the headers members.  The heat transfer tubes are adapted to transfer heat between fins on the exterior of the tubes and a working fluid in liquid or gaseous phase within the tubes.  A pressure drop minimizing tube passes between the headers and has a cross sectional area significantly larger than the heat transfer tubes.   The pressure drop minimizing tube is adapted to carry the working fluid in a gaseous phase either as an inlet, when the heat transfer assembly is utilized as a condenser, or as an outlet, when the heat transfer assembly is utilized as an evaporator.   A member connects the pressure drop minimizing tube at one end to at least two of the heat transfer tubes for condensation to a liquid, when the assembly is utilized as a condenser,  or transferring gaseous working fluid from the heat transfer tubes to the pressure drop minimizing tubes,  when the assembly is utilized as an evaporator.   A plurality of header tubes connect the heat transfer tubes to one another to carry the working fluid through the assembly.   The pressure drop minimizing tube is preferably within the heat transfer tube array and within the fin pattern imposed on the heat transfer tubes.

Title: Method of manufacturing resin overlay plate
Inventor: MATSUMOTO MITSUO
IPC: B32B27/12
Filed: 1990-05-09
Abstract: ABSTRACT OF THE DISCLOSURE     In forming a polyolefin resin film on the surface of a wood plate, the polyolefin resin film is first formed on a non woven fabric, to manufacture a composite sheet having the polyolefin resin film formed on the non woven fabric.     Then, this composite sheet is superimposed on the wood plate through adhesive with the non woven fabric being on the side of the wood plate and then, pressed to bond the composite sheet to the wood plate.     The composite sheet having the polyolefin resin film formed on the non woven fabric is manufactured, and this composite sheet on the side of the non woven fabric is bonded to the wood plate.  Accordingly, reactive curing adhesive commonly employed can be utilized for bonding the composite sheet to the wood plate.  Furthermore, in bonding the composite sheet to the wood plate by heating, the non woven fabric, on the side of which the composite sheet is bonded, in the composite sheet becomes an escape route of water vapor emitted from the wood plate, thereby causing no bubble troubles.  Consequently, in the processes of manufacturing the wood plate such as plywood, a particle board or a wafer board, the composite sheet can be bonded to the wood plate simultaneously with the manufacture of the wood plate.

Title: Angling device
Inventor: SCHMIEGEL HUBERT
IPC: A01K91/10
Filed: 1991-05-31
Abstract: ABSTRACT    An angling device in which a spring  inside  a housing  is loaded by an arm connected to the spring and movable along a main slot in the housing.  The arm is movable into a lateral slot so as to hold the spring in loaded condition.  Guide apertures are provided exteriorly of the housing and also upon an outward extension of the arm to enable a fishing line to be attached easily and the line may extend as a single length through the apertures to a fishing hook.  A fish pulling upon the hook will cause the arm to return into the main slot thereby releasing the spring to force the arm back along the main slot and jerk the line.  As the guide apertures are exteriorly of the housing, no internal line attachment is required and the housing may be completely closed except for the slots thereby resisting entry of contaminants into the housing.
