Patent CA-2183395-C (CA)
Inventor: OZAKI YASUO
IPC: A47B53/02
Filed: 1996-08-15
Granted: 1999-04-06
Abstract: A method of the invention detects a machining load acting on a tool during a machining process,  computes estimatingly an abrasion quantity of the tool on the basis of the machining load and a tool abrasion characteristic registered in advance in a memory, and changes automatically a tool position compensation quantity on the basis of the tool abrasion quantity.  The estimating computation of a tool abrasion quantity is performed by, for example, obtaining in advance a tool abrasion coefficient on the basis of a tool abrasion quantity per unit time in case of taking a main spindle load current value as a reference machining current value, and integrating for a machining time the product of a ratio of a main spindle load current value during an actual machining process to the reference current value and said tool abrasion coefficient.

Title: Improved catch basin
Inventor: MONTEITH JOSEPH GORDON
IPC: E03F5/04
Filed: 1997-05-28
Granted: 2001-06-26
Abstract: An improved catch basin is constituted by a cylindrical container with a partition dividing the internal volume into a lower compartment and an upper compartment. The partition includes an intake region and an outlet region, each communicating with a vertical pipe extending downwardly from the partition and opening into the lower treatment chamber at an intermediate location therein, the intake region and the outlet region being diametrically opposite one another.  The partition defines a central, oblique ramp which urges entering liquid in the direction of the intake opening of the intake region. Thus, under conditions of low liquid flow into the catch basin, all entering liquid will be directed to the intake region, descending along the intake conduit and into the lower compartment.  Conversely, under conditions of high liquid flow into the catch basin, a portion of the liquid will overrun the ramp and gain direct access to the outlet region, from which it will exit the catch basin.

Title: Thermoplastic polymer composition and method of molding parts with reduced shrinkage
Inventor: MCALPIN JAMES JOHN
IPC: C08L23/08
Filed: 1995-12-14
Granted: 2006-10-31
Abstract: A thermoplastic polymer composition incorporating at least about 50 wt.% polypropylene, at least about 20 wt.% of an elastomer such as EP rubber and at least about 4 wt.% plastomer. The plastomer is preferably a single site catalyzed ethylene based copolymer having a density less than about .915 g/cm3. By adjusting the amount of the plastomer in the composition, considerable control is secured over post-mold shrinkage of components produced through injection molding operations utilizing the composition. The composition can be prepared as a reactor blend or a melt blend. The composition is particularly useful in producing large components such as bumpers and exterior trim fascia for automobiles.

Filed: 1996-04-15
Granted: 2001-01-16
Abstract: An eddy current drive (711) has an electromagnet (15, 17) and an armature (19). Either one of the electromagnet or the armature is coupled to a motor shaft (31) so as to rotate therewith, while the other is coupled to a load portion (21). The motor can rotate at a continuous speed, while the speed of the load portion can vary by varying the energization of the electromagnet, so as to vary the coupling between the electromagnet and the armature. The electromagnet is energized by way of bearings (613, 615). The bearings provide a rotary coupling. In another embodiment, an electrical generator (713) is provided. The rotation of the motor shaft (31) generates electrical current that is used to energize the electromagnet. The amount of the electrical current that is provided to the electromagnet can be varied to vary the output speed of the load portion.

Abstract: Cryptographic methods are disclosed, which allow a prover party, who holds a number of secrets, to demonstrate satisfiable formulas of propositional logic, wherein the atomic propositions are linear relations between the secrets. The demonstration reveals no more information than is contained in the formula itself. Some implementations allow an unlimited number of such demonstrations to be made, without revealing any additional information about the secrets, whereas other implementations ensure that the secrets, or some of the secrets, will be revealed, if a demonstration is performed more than a predetermined number of times.

Title: Cryptographic method and apparatus for restricting access to transmitted programming content using program identifiers
Inventor: WOOL AVISHAI
IPC: H04N7/16
Filed: 1998-07-28
Granted: 2002-01-08
Abstract: A system for restricting access to transmitted programming content is disclosed, which transmits a program identifier with the encrypted programming content. A set-top terminal or similar mechanism restricts access to the transmitted multimedia information using stored decryption keys. The set-top terminal preferably receives entitlement information periodically from the head-end, corresponding to one or more packages of programs that the customer is entitled to for a given period. Each program is preferably encrypted by the head-end server prior to transmission, using a program key, KP, which may be unique to the program. The set-top terminal uses the received program identifier, p, together with the stored entitlement information, to derive the decryption key necessary to decrypt the program. Each of the k-bit program keys, KP, used to encrypt transmitted programs is a linear combination of a defined set of k-bit master keys, ml .... mn. The head-end server preferably generates a new set of master keys for the matrix, M, once per billing period. Since each program key. KP, is a linear combination of the set of master keys, M, a customer desiring r programs, obtains access to the smallest linear subspace of programs, U, that contains those r programs. In addition, a package consists of (2i - 1) program identifiers for some i less than n, which need not all be assigned to programs. An optional check matrix, C, allows the set-top terminal to determine,  in advance, whether a received program is in the entitled subspace, U.
