Filed: 1998-11-18
Abstract: In the pinned connections between frame members of articulated machines, it is typical to utilize one or more pin assemblies that have one or more spaces between the various components in the pin assembly. The present invention comprehends a pin assembly (10) that utilizes a first plurality of fasteners (82) to secure a first lock plate (72) to one of a pair of frame members (12, 18). A first shim assembly (86) is included to remove any space between components along a first path of force transfer. A second plurality of fasteners (92) is utilized to mount a second lock plate (90) to a pin member (44). A second shim assembly (94) is included to remove any space between components along a second path of force transfer. The fasteners (82, 92) work in conjunction with one another to greatly reduce flexing, and thereby the tendency for the fasteners to loosen, that occurs in a pin assembly (10) due to the transfer of forces therethrough.

Patent CA-2283279-A1 (CA)
Title: Appareil de communication sans fil et procede
Inventor: SOLIMAN SAMIR S
IPC: H04W48/18
Filed: 1998-03-04
Abstract: L'invention concerne un appareil (100) de communication qui se commute automatiquement et en continu à un système de secours disponible lorsqu'il est incapable d'établir une tentative d'émission d'appel sans demander à l'utilisateur de prendre des actions positives en vue de sélectionner le système de secours ou de recommencer une émission d'appel. L'appareil (100) de communication sans fil comporte un poste émetteur-récepteur (104) et un processeur (104). Le poste émetteur-récepteur (107) émet et reçoit des messages et des signaux. Le processeur (107) génère un premier message de signalisation, destiné à être transmis à un premier système de communication, et génère un second message de signalisation destiné à être transmis à un second système de communication au cas où le poste émetteur-récepteur ne reçoit pas de message d'accusé de réception du premier système de communication. Ce procédé fait diminuer le pourcentage d'appels infructueux en assurant un retardement des tentatives d'émissions d'appels en attente jusqu'à ce que le service soit finalement obtenu. En cas, soit de dépassement du nombre maximum de séquences d'accès (liaison de retour limitée), soit de la non obtention de la liaison aval du système de communication préféré (liaison aval limitée), on ne demande pas à l'utilisateur de recommencer l'émission d'appel, ce qui transforme ainsi un appel infructueux potentiel en un succès.

Title: Method to lower the formation of clods and the clustering tendency of reducible iron containing agglomerated material, in particular pellets
Inventor: KLEMO ROGER
IPC: B01J2/00
Filed: 1999-01-14
Abstract: The invention relates to a method for reducing the formation of clods and the clustering tendency of reducible iron-containing agglomerated material, particularly so-called pellets, whereby the reducible iron-containing agglomerated material, following a desulphurisation process that takes place after a sintering process during the manufacture of the said pellets, is given an outer layer of clustering-reducing material in the form of a liquid suspension of particulate material. According to the invention, a more even distribution of the coating on the surface of the agglomerate is achieved in that the application of the liquid suspension takes place during tumbling in a drum that is designed so that the agglomerate together with the liquid suspension can essentially pass freely through it.

Inventor: CHEIKH NORDINE
IPC: A23L19/18
Filed: 1998-06-16
Abstract: Fructose-1,6-bisphosphate aldolase (FDA) is an enzyme reversibly catalyzing the reaction converting triosephosphate into fructose-1,6-bisphosphate. In the leaf, this enzyme is located in the chloroplast (starch synthesis) and the cytosol (sucrose biosynthesis). Transgenic plants were generated that expess the E. coli fda gene in the chloroplast to improve plant yield by increasing leaf starch biosynthetic ability in particular and sucrose production in general. Leaves from plants expressing the fda transgene showed a significantly higher starch accumulation, as compared to control plants expressing the null vector, particularly early in the photoperiod, but had lower leaf sucrose. Transgenic plants also had a significantly higher root mass. Furthermore, transgenic potatoes expressing fda exhibited improved uniformity of solids.

Abstract: Transcriptional activators which differ in their activation potential by more than 3 orders of magnitude are provided. The transactivators are fusions between a DNA binding protein (e.g., a Tet repressor) and minimal transcriptional activation domains derived from Herpes simplex virus protein 16 (VP16). Substitution mutations at amino acid position 442 within the minimal VP16 domain provide transactivators with differing transactivation ability. Moreover, chimeric activation domains comprising both wild type and mutant minimal VP16 domains provide additional variants with differing transactivation ability. Various aspects of the invention pertain to nucleic acid molecules, vectors, host cells, fusion proteins, transgenic and homologous recombinant organisms and methods of regulating gene transcription.

Inventor: HEIKKILAE GUNNAR
IPC: H04W24/00
Filed: 1998-06-23
Abstract: An improved method and system of measuring the perceived speech quality in mobile telecommunications network are disclosed herein. In an embodiment of the invention, the method uses both radio link parameters and an objective measuring technique performed on received signals to estimate the speech quality perceived by the end-user. A radio link processing stage extracts temporal information from a set of available radio link parameters such as the BER, FER, RxLev, handover statistics, soft information, and speech energy.  Concurrently, a speech processing stage is used to process a sequence of original signals and received signals, obtained from the output of a telecommunications system. The signal sequences are processed by an objective measuring technique such as Perceptual Speech Quality Measure (PSQM). The outputs from the radio link processing and speech processing stages are utilized to calculate an estimate for speech quality.
