Title: Truck trailer body with sliding nestable canopies
Inventor: LEONI MICHAEL C
IPC: B60P7/02
Filed: 1999-11-12
Abstract: A truck trailer body system has an elongated cargo-supporting bed with front and rear bulkheads and sliding nestable rigid enclosure sections, called canopies, which are movable between the bulkheads. The canopies are positionable for completely enclosing and protecting cargo from environmental damage during transportation or storage, and also for selectively providing largely unfettered access to the cargo for any purpose, such as inspection, loading, and unloading, as desired. The enclosure sections or canopies ride on roller mechanisms for movement along tracks extending along either side of the trailer bed over its entire length.  The individual canopy sections, when unlocked, slide relatively freely along the length of the tracks. Locking systems are provided to secure the canopies in a fixed position on the trailer so as to prevent unwanted movement, and to prevent them from decoupling from one another.

Coils of wire are created as each pair of slots is wound. The invention will typically be used to form multiple coil windings on a single stator.
Patent CA-2295819-A1 (CA)
Title: Piezoelectric motor
Inventor: CUNNINGHAM JOHN
IPC: H01L41/09
Filed: 1998-07-07
Abstract: A piezoelectric motor including a motor body, a compliant layer in communication with the motor body, and a predetermined number of legs in communication with the compliant layer, which urges the legs into engagement with a substrate. Each of the legs includes a piezoelectric wafer, preferably operated in the shear mode. The actuation of a piezoelectric wafer causes the corresponding leg to be displaced relative to a substrate. This displacement results in the transfer of strain energy to the compliant layer. The energy stored in the compliant layer may be released, causing the motor to advance along the substrate. The legs may be capable of moving independently from one another and also may be capable of moving sequentially or in predetermined groups or units. The legs also may be arranged in pairs with the leg pairs being capable of simultaneous actuation. The motor is capable of maintaining a high holding force in the absence of a power input.

Title: Method for racemic biochemical resolution of cis- and trans- pyrrolopiperidine
Inventor: DREISBACH CLAUS
IPC: C07D471/04
Filed: 1998-08-01
Abstract: Cis- and trans-pyrrolopiperidines are advantageously separated into their optical isomers when monoacylating by enzymatic process a mixture containing (R,R)- and (S,S)-pyrrolopiperidine or (S,R)- and (R,S)-pyrrolopiperidine, thereby obtaining a mixture (I) containing (R,R)- and (S,S)-6-acyl-pyrrolopiperidine or (S,R)- and (R,S)-6-acyl-pyrrolopiperidine. Said mixture (I) is then again acylated by enzymatic process, thereby obtaining a mixture (II) containing (S,S)-1,6-diacyl- and (R,R)-6-acyl-pyrrolopiperidine or (S,R)1,6-diacyl- and (R,S)-6-acyl-pyrrolopiperidine; the enzyme and optionally the solvent and the excess acylating agent are then separated from the mixture (II), and the rest is treated with an aqueous acid and the (S,S)-1,6-diacyl-pyrrolopiperidine or the (S,R)-1,6-diacyl-pyrrolopiperidine is separated by extraction and the extraction residue is alkalinized, and the (R,R)-6-acyl-pyrrolopiperidine or the (R,S)-6-acyl-pyrrolopiperidine is separated by extraction. From these acylated isomer-free derivatives, the free base can optionally be prepared according to the usual methods for separating acylated groups.

Title: Method for data transmission of transmission channels in a digital transmission system
Inventor: BERENS FRIEDBERT
IPC: H03M13/13
Filed: 1998-07-29
Abstract: The invention relates to a method for data transmission on transmission channels in a digital transmission system, wherein turbo-coding for channel coding is carried out in a turbo-coder on the sender side and turbo decoding is performed with soft decision output signals on the receiver side. Service quality is determined on the basis of variances in the soft decision output signals in the turbo-decoder with the purpose of attaining improved service quality. The coding rate is adjusted by adapting dotting in such a way that a predetermined service quality is achieved. Alternatively, the number of decoding iterations is adjusted depending on the service quality. When a MAP  symbol evaluator is used in the receiver side, the variances .sigma.2LLR of the soft decision output signals of the turbo-decoder are determined and the bit error rate is estimated on the basis of the variances .sigma.2LLR to measure service quality.
Patent CA-2302194-A1 (CA)
Inventor: SCHAUDER COLIN DAVID
IPC: H02M7/521
Filed: 1998-08-26
Abstract: A three-phase dc-to-ac power inverter includes a dc power source with a first dc node for positive voltage, a second dc node for negative voltage, and a third dc node for zero voltage. A control circuit, responsive to an inverter voltage vector reference demand signal with a voltage magnitude reference demand component and a voltage phase reference demand component, generates pole control signals for the three-level pole circuits using logic circuitry which combines phase indexed digital waveform values stored in a pair of lookup tables (114, 116). The pole control signals (118, 120) force the threelevel pole circuits to generate a set of phase-shifted waveforms with zero voltage components. The phase-shifted waveforms are combined by a set of transformers to produce a three-phase output voltage with a harmonic content lower than the harmonic content of the phase-shifted waveforms.

Abstract: La présente invention concerne l'identification de sites d'amorce d'amplification et d'amorce de séquençage qui permettent le typage basé sur la séquence de chacun des gènes HLA classiques dans des réactions d'une solidité et d'une stabilité élevées sans perte d'allèle. Pour déterminer la séquence d'ADN, et par conséquent le type d'au moins un exon d'un gène HLA-A, HLA-B et HLA-C présent dans l'échantillon, on combine l'échantillon avec un mélange réactionnel d'amplification contenant les amorces d'amplification et on l'amplifie pour former un produit d'amplification comprenant l'exon 2 et l'exon 3 du gène dans un seul fragment. On combine alors le produit de l'amplification avec un mélange réactionnel de séquençage contenant un ou plusieurs oligonucléotides amorces de séquençage qui s'hybrident avec les régions conservées du produit de l'amplification. Les oligonucléotides amorces de séquençage produisent de façon efficace des fragments de séquençage de tous les allèles connus de l'exon 2 ou de l'exon 3 du gène dans des conditions appropriées à la production de fragments de séquençage. On évalue ensuite les fragments de séquençage pour déterminer la séquence de l'exon 2 ou de l'exon 3 du gène de l'échantillon.
