Patent CA-2452197-A1 (CA)
Inventor: STRATICO GIANFRANCO
IPC: H02K15/095
Filed: 2003-12-08
Abstract: The present invention concerns forming wire coils by simultaneously winding a plurality of wires onto a dynamo-electric machine component. In order to maximize the amount of wire that can be placed in the spacings of the dynamo-electric machine component, the turns of the wire coil must be regularly disposed without twisting the plurality of wires onto each other. Current winding apparatus may allow certain portions of the wire turns to unevenly accumulate and locally bulge outward from the collection of wire coils. Such bulges, especially in consideration of the limited spacings available on an dynamo-electric machine component, may interfere with or access to the spacings by a wire dispensing member during the winding process. The present invention proposes to perform multiple-wire winding processes that avoid wire twisting and improper disposition of the wires.      Further, the present invention proposes to improve the ability of the wire dispensing member to traverse the spacings on the component. As a consequence, the winding processes performed with the present invention are less likely to be hindered by interference and are capable of obtaining more wire fill within the component spacings and higher winding speeds.

Title: Economically armor a military vehicle
Inventor: HASSAN ELGOHARY
IPC: F41H5/04
Filed: 2003-12-31
Abstract: A new method to economically armor a military vehicle enabling it to endure more developed, accurately directed and lethal piercing weapons, bombs and mines than what the best-armored vehicles can endure presently with a minimal increase in its weight (because of armoring).    To armor the vehicle we use similar groups of cylinders that have a common center (The cylinders with bigger diameters placed outer to those with less diameters).    We use three rows of similar groups of cylinders placed between four sheets of metal. Both the sheets and cylinders are made of the hardest Manganizesteel alloy known with a thickness that depends on the diameter of the cylinders (Outer cylinders being thicker than inner ones). The maximum diameter of the outer cylinder in each of the inner rows should be half the diameter of the outer cylinder in the row outer to it.    We armor the area between the engine and the rest of the vehicle, the rear, the two sides, the floor and the sealing of the vehicle to insure the maximum possible protection of the crew fired on by different kinds of weapons.
