Patent CA-2221447-A1 (CA)
Title: Mobile telephone system
Inventor: MUNDAY PETER ROBERT
IPC: H04M3/22
Filed: 1996-07-17
Abstract: A mobile telephone system consists of a base transceiver station (BTS) that provides radio communication with a mobile handset (MS) and also communicates with a control station (BSC) through a communication link in the form of a leased line which provides a first communication path (P1) with a predetermined bandwidth for signals communicated between the BTS and the BSC.  A communication network in the form of an ISDN is used to provide a selectively connectable second communication path (P2) between the BTS and the BSC so as to augment the bandwith available for the signals during periods of peak demand. In order to accommodate different call connection times in the system through the leased line and the ISDN, the BSC/BTS are arranged to produce call connection signals (CLI1, CLI2) that initiate billing at the same time irrespective of the path P1, P2 used to make the call connection.
Patent CA-2222835-A1 (CA)
Inventor: ARROWSMITH PETER
IPC: G01N27/22
Filed: 1997-11-28
Abstract: There is provided a detector for detecting conductive contaminants entrained in an airflow. The detector comprises first and second electrically conductive meshes mounted in a spaced apart relationship to provide an operational gap. Each of the meshes is sized to provide a relatively large surface for substantially intersecting the airflow and is sufficiently porous so as not to substantially attenuate the airflow. The meshes form part of an energizable electric circuit wherein the operational gap constitutes a discontinuity of the circuit. The detector includes a capacitor connected in parallel to the portion of the circuit containing the operational gap. There is a release of a charge stored in the capacitor through the circuit discontinuity when one of the conductive contaminants simultaneously contacts the first and second meshes. The detector further provides for indication of the discharge of the capacitor and thereby the presence of one of the airborne conductive contaminants entrained in the airflow.

Title: Radio location with enhanced z-axis determination
Inventor: SANDERFORD HUGH BRITTON JR
IPC: G01S5/06
Filed: 1996-06-06
Abstract: An enhanced system for calculating the Z-Axis, or relative height or altitude, of a radio beacon. The present invention uses a barometric pressure sensing device co-located with the radio emitter (203) to transmit data representing relative altitude. To further enhace the Z-Axis determination, one or several barometric sensors, located at known heights, are positioned around the city to provide real time barometric data. The real time data is used to form a differential correction factor which is compared to the time varying barometric sensor co-located with the radio emitter, thereby yielding Z-Axis accuracies of up to one (1) foot. Since the altitude essentially becomes a "known", this information can also be used in the least squares fit algorithm to enhance the X and Y determination as well.

Inventor: WHITEHEAD STEPHEN
IPC: C07K14/31
Filed: 1996-06-06
Abstract: L'invention porte sur un nouveau système de clonage et d'expression de gènes dans des bactéries gram positives. Le système d'expression se base sur le fait que de nombreuses bactéries gram positives effectuent le tri de protéines de la surface des cellules à l'aide de séquences de signalisation N-terminales à activité cis et de régions d'ancrage C-terminales. En particulier les signaux de tri des cellules de la protéine streptococcique M6, molécule superficielle bien connue, servant à construire le système d'expression gram positif SPEX (Streptococcal Protein Expression). L'expression s'obtient par clonage du gène d'intérêt dans une cassette SPEX appropriée qui est ensuite introduite de manière stable dans un hôte bactérien tel qu'un commensal humain du type Streptococcus gordonii. Selon le vecteur SPEX utilisé, il est possible d'ancrer des protéines de recombinaison à la paroi cellulaire avant leur libération par clivage endoprotéolytique spécifique ou sécrétées dans le milieu de culture pendant la croissance des bactéries. Le recours à des bactéries sans protéases extracellulaires devrait protéger les protéines sécrétées de la dégradation protéolytique. Plusieurs vecteurs d'expression du système produisent également des protéines de recombinaison à marquage spécifique permettant la purification en une seule étape du produit résultant.

Abstract: A suitable automatically operating apparatus is proposed for producing reinforcing cages (3, 4) for rectangular pipes made of concrete. Longitudinal-wire sections (5), which are parallel to the pipe axis, are held together in a framework (9). The latter essentially comprises a perforated frame (13), which cannot be moved in the longitudinal direction, and a receiving frame (18), which can be displaced relative to the perforated frame. Rectilinear transverse-wire sections, angles or bent brackets are welded onto the longitudinal-wire configuration, to be precise onto the respective side surfaces of the longitudinal-bar configuration in a freely selectable manner. Fitting apparatuses which can be displaced perpendicularly with respect to the longitudinal-wire sections are used for this purpose. In addition to the wire thickness, it is also possible to select the spacings between the transverse-wire sections provided in each case. In the example, the framework (9) can be rotated about a vertical axis on a carousel (10), in each case two mutually opposite fitting apparatuses interacting with two welding apparatuses arranged transversely thereto.      The necessary transverse-wire sections are finished off in each case during the welding operation. The completed reinforcing cages (3, 4) are removed, and inserted one inside the other, by crane (19 to 25).
