Patent CA-2126732-C (CA)
Inventor: SBALCHIERO FEDERICO
IPC: H01R43/14
Filed: 1994-06-24
Granted: 2005-09-20
Abstract: commutators of armatures for electric motors or other dynamo-electric machines are finished by subjecting them to inspection and turning operations.     The first inspection operation determines the minimum amount of material that can be cut while producing a high quality armature. This determination may indicate that no formal turning is required, only finishing.      The turning operation, if applicable, cuts the commutator to a substantially cylindrical shape which is substantially concentric with the axis of rotation of the armature. The finishing operation, which may be performed by the same mechanism as the turning operation, imparts a desired axial roughness to the. cylindrical commutator surface. The commutators may be inspected after the turning and finishing operations to generate data useful for such purposes as automatically modifying the turning and finishing operations performed on subsequent commutators.

Title: Anti-fraud credit card dispatch system
Inventor: SEILER DIETER G
IPC: G07F7/12
Filed: 1993-12-24
Granted: 1999-07-13
Abstract: An anti-fraud system for the dispatch of credit cards to customers, rendering the renewal credit card useless to anyone other than the intended customer. Validation of the renewal credit card is accomplished at aay retail outlet by means of a timed sequence at the transaction processing computer which ensures that any first-time sales authorization request under the renewal credit card is followed immediately within a prescribed time interval by a processing of the old credit card number and expiry date. The system also operates if the old credit card is tendered first at a sales outlet after the renewal credit card has been issued. This unique sequence of events will then automatically invalidate the old credit card, validate the renewal credit card, and indicate to the credit card issuing company that the customer has acknowledged receipt of their renewal credit card. Since both the old credit card, and the renewal credit card are required in order to validate the renewal credit card, an unauthorized party in illegal possession of the renewal credit card only, cannot use it.

Title: Two component external mix spray gun
Inventor: FRITZ ALAN H
IPC: B05B7/12
Filed: 1995-10-30
Granted: 1999-03-30
Abstract: A two component external mix spray gun having a pneumatically operated valve for controlling the injection of a catalyst into pattern shaping air passages in the gun. The catalyst is contacted with the atomized fluid externally to the spray gun. A trigger sequentially operates air and fluid valves to provide atomization air and pattern shaping air prior to opening the fluid valve. The pneumatic catalyst valve is responsive to an increase in the air pressure downstream from the air valve to inject the catalyst into the pattern shaping air prior to the opening of the fluid valve. The catalyst impinges on the atomized fluid externally to the spray gun along with the pattern shaping air. The invention may be incorporated in either a hand held spray gun with a manual trigger or an automatic spray gun with a controller.

Title: Spin-stabilized projectile with a payload
Inventor: ETTMUELLER PETER
IPC: F42B12/36
Filed: 1996-06-18
Granted: 2000-02-01
Abstract: A  spin-stabilized  projectile  containing  a  payload  is presented.   The projectile includes a projectile body with a payload chamber that may be laterally defined by a projectile casing, on top by an axial fixing device for a payload disposed in the payload chamber, and on the bottom, by a dividing wall.  The projectile casing may include axial grooves on the inside, which on the contribute to the fixing of the payload and include intended break zones for freeing the payload.  Below the dividing wall, an opening charge may be disposed, which includes complete radial contact and is axially spaced apart from the dividing wall by a damping device.   The detonation of opening charge causes the projectile casing to immediately split open at the intended break zones to release,  by centrifugal force,  the payload from the payload chamber.   The damping device prevents the payload from being damaged in the region of the dividing wall and prevents the release of the payload from being interrupted.

Abstract: Compression seam welding process and apparatus, wherein two plate-like workpieces (12) having different thicknesses are fed and guided by a guiding device (14, 18U, 18S) such that a length WH of contact of a thick plate-like workpiece (12H) with one (20U) of two roller electrodes (20) is smaller than a length WM of contact of a thin plate-like workpiece (12M) with the other roller electrode (20S)S. In this arrangement, the amount of compression of the thick plate-like workpiece (12H) by the roller electrode (20U) is greater than that of the thin plate-like workpiece (12M) by the other roller electrode (20S), so that an interface (G) of the two plate-like workpieces is positioned intermediate between the pair of roller electrodes, so that a weld nugget (N) formed intermediate between the roller electrodes extends across the interface, permitting the weld to have sufficient strength because a nugget ratio RN, which is a ratio of a width dimension WN of the weld nugget in the direction of the interface to a width dimension WG of the interface, is increased.

Abstract: A method and apparatus for generating cryptographic keys for use in a cryptographic system includes a key generator for generating a subset of reduced key space keys from a larger B-bit cryptographic key. The subset of keys is distributed randomly over a B-bit key space according to a secret hash or distribution key to provide cryptographic keys with a larger apparent work factor. The work factor depends on the number of possible different keys for a given key bit length, and provides a corresponding level of decoding difficulty to a hostile attacker. Without knowledge of the secret hashing key, the work factor of the cryptographic key appears to be up to S=2B, and an attacker must make up to 2B guesses to determine a specific key with certainty. This level of difficulty will typically be too computationally intense for the attacker to break the system. However, with knowledge of the secret hashing key, the work factor is significantly lower. Thus, the work factor of the key can be reduced to a level which is small engough to satisfy governmental export or import requirements without reducing the protection level or strength of the system. A single cryptographic key generator (engine) can be easily adapted for use in different countries, where different work factors are required.
