Title: A method for production of a polyethylene laminated metal sheet
Inventor: OKAMURA TAKAAKI
IPC: B32B15/08
Filed: 1992-06-18
Abstract: ABSTRACT OF THE DISCLOSURE    A polyethylene film is heat bonded to a metal sheet provided with a layer of hydrated chromium oxide, and possibly a layer of metallic chromium under the oxide layer.  The laminated metal sheet is  then  rapidly  quenched,  and  the  polyethylene  laminate  is irradiated  with  an  electron  beam,  gamma  rays,  or  X-rays.          Alternatively, the polyethylene film may be irradiated prior to lamination.    The laminated metal sheet exhibits excellent resistance to steam  and  hot water  and  does  not  delaminate  during  forming operations such as can-making.

Patent CA-2081917-A1 (CA)
Title: Carbon canister purge system
Inventor: COOK JOHN EDWARD
IPC: F02M25/08
Filed: 1991-04-26
Abstract: A pulse width modulated solenoid-actuated valve (12) and a vacuum-actuated valve (14) are cooperatively associated such that the purge system possesses both accurate control at low purge flows and the capacity for handling much higher flows. The two valves are in parallel paths between the canister and the manifold. Below a certain duty cycle of the solenoid-actuated valve, only its path is open. At higher duty cycles, both flow paths are open. An orifice (46) is provided in the flow path containing the solenoid-actuated valve so that as this valve increasingly opens, a vacuum signal at a tap (44) between the orifice and the solenoid-actuated valve also increases. This vacuum signal is applied to a control port (34) of the vacuum-actuated valve to cause the latter to open upon attainment of a certain flow through the solenoid-actuated valve.

Title: Induction heating tool
Inventor: MCGAFFIGAN THOMAS H
IPC: H05B6/10
Filed: 1993-04-13
Abstract: A jaw-like cylindrical tool for producing a strong electromagnetic field for causing a Curie point heater to be energized having a curved cross-section that brings the two edges of the jaw-like structure into contact, Closely spaced conductors lie along the inner surface of the structure transverse to its axis while widely spaced conductors lie transverse to said axis along the outer surface of the structure.  The inner surface of the structure has a plurality of axially extending ferrite rods lying immediately adjacent the inner surface conductors.  The inner and outer surface conductors are connected so that the currents flow in opposite directions, the outer conductors reducing electromagnetic radiation while the ferrites and inner conductor spacing produce a strong central magnetic field irrespective of the field created by the opposing field produced by the outer conductors.  The tool may be manufactured by laying each ferrite rod longitudinally along the flat surface of a D-shaped mandrel with the rods lying side by side transversely.  Conductors are wrapped transversely around the curved surface of the mandrel and over the ferrite rods.  The rods and conductors are bonded to one another, removed from the mandrel and the resulting structure curved until the longitudinal edges of the structure are in contact with one another.

Title: Broadband antennas
Inventor: PODGORSKI ANDREW S
IPC: H01Q13/20
Filed: 1993-05-13
Abstract: A structure for use in an antenna or as a broadband electromagnetic field simulator having an open horn TEM waveguide coupled to launch energy in a strip line formed between a forwardly extending plate section and a ground plane. When used as a simulator the test volume is located outside the horn between the forwardly extending plate section and the ground plane. The plate section which functions gas a radiating element initially extends parallel to the ground plane and then curves downwardly to terminate adjacent it. In alternative embodiments the plate section extends upwardly, initially with an exponential configuration. In a simulator embodiment it may then terminate at a vertical, grounded wall faced with anechoic material. The horn contains a flat conductor plate positioned parallel to and spaced from the top edge defining an asymmetrical transmission line within the horn. This plate conductor can be coupled to the forwardly extending plate section directly, by means of an RLC coupling network or by means o~ an array of literally spaced conductors.
