Patent CA-2249918-A1 (CA)
Inventor: HENGEVELD L DAAN
IPC: A01G23/00
Filed: 1998-10-09
Abstract: A slack puller has symmetrical sheave assemblies on each side of a cable path. The sheave assemblies each include a driven sheave mounted on an arm. When the sheaves are engaged with the cable by an actuator, tension in the cable pulls the sheaves in a way which tends to increase the compressional forces exerted by the sheaves on the cable.      The self actuating nature of the slack puller allows compressional forces on the cable to be kept small until the cable comes under tension. The sheaves are driven by positive displacement hydraulic motors connected in series with a hydraulic pump. This permits the sheaves to turn quickly when the cable is not under tension and slows the sheaves as tension in the cable increases. The slack puller operates more quickly and causes less cable damage than conventional slack pullers. The slack puller has particular application in skyline logging operations where its compact size is an additional advantage.

Title: Segmented screw traversing mechanism
Inventor: CARSTENSEN PETER T
IPC: F16H25/24
Filed: 1997-06-24
Abstract: The linear traversing apparatus (10) includes a lead screw (12) formed from a plurality of lead screw segments (14, 16, 18) which are supported at regular intervals, that is, at the intersection of adjacent lead screw segments, along a span by fixed hollow cylindrical splice points (20, 22). The lead screw segments (14, 16, 18) include external threading which engages the internal threading of a C-shaped spanning nut (28). The C-shaped spanning nut (28) has a circumferential portion removed so that the spanning nut (28) can clear the fixed hollow cylindrical splice points (20, 22) and associated support structure (24, 26) as the spanning nut (28) traverses the lead screw (12) in response to the rotation of the lead screw (12) and the inhibition of rotation of the spanning nut (28). The rotation of the spanning nut (28) is inhibited typically by mechanical communication with an instrument or other device which is engaged by a rail or a slot parallel to the longitudinal axis of rotation of the lead screw (12).

Abstract: A method and system for delivering location identification information (name of country, city, street address, etc.) to a calling party or to a called party is described.  Location identification information may be stored in a database resident at a Service Control Point (SCP) in a CCS7 network. By making use of AIN and its triggering capabilities, a request for location identification information from an SCP is made by an SSP at the initiation of a call from a calling party to a called party.  The location identification information retrieved by the SCP can be delivered to either or both of the calling and called parties.  Alternatively, there is provided at least one database containing location identification information resident at the central office switch SSP to which an end user's Customer Premises Equipment (CPE) is connected. When a call is initiated, the calling party's location identification information would be delivered to the called party's CPE.  Concurrently, location identification information concerning the called party would be retrieved by the called party's SSP from a local database, and delivered to the calling party's CPE.
Patent CA-2256987-A1 (CA)
Inventor: LING PETER
IPC: H01M50/172
Filed: 1998-12-23
Abstract: A terminal assembly for sealing and electrically isolating a conducting terminal from a container of an electrolytic device uses a lock nut and a single-piece deformable gasket. When the lock nut is threaded down the terminal, an inwardly tapered sleeve of the lock nut cooperates with an outwardly tapered zone of the gasket to force the gasket to surround the opening of the container and to seal the terminal before compression is applied. Reliable sealing and electrical insulation are provided because predetermined axial and radial compression forces are generated on the opening of the container. A robust sealed terminal is provided while over compression of the single-piece gasket is prevented.

Title: Molten metal immersion bath for wire fabrication
Inventor: COWIE GORDON BERNARD
IPC: B05C3/10
Filed: 1999-02-03
Abstract: An apparatus and related process for immersing a moving wire within a both of molten metal is applicable to wire forming processes. A flat-bottomed tray has at one end a nozzle for dispersing molten metal across the floor of the tray, from a first end to a second end, in a sheetlike flow. The nozzle preferably includes a slot-like opening, and is associated with a chamber for receiving a supply of pressurized molten metal for discharge through the slot. The metal is discharged with sufficient velocity to create a hydraulic jump or standing wave, whereby the crest of the wave is elevated above the tray end walls. Within the wave, molten metal experiences a turbulent flow in a direction against the travel of the wire array. The wire array passes through the wave, thereby experiencing immersion while being drawn through the apparatus in a straight path without substantial declination. An arrangement of pumps, heaters and a reservoir for the metal permit the metal to be recirculated through the device and maintained in a molten state.

Title: Movement-resistant horse rug
Inventor: MACGUINNESS THOMAS PETER
IPC: A01K13/00
Filed: 1996-12-18
Abstract: A horse rug (10) comprises a front closure means (14) which can be engaged to secure the rug to a horse when the opposed front edges (15, 15') of the rug (10) are brought together, the point of closure being positioned, in use, not lower than the point of shoulder of the horse. The rug (10) is provided with strips of webbing (17, 18 and 17', 18') on each of its front edges (15, 15') respectively, which webbing forms part of the closure means (14). The strips of webbing (17, 18 and 17', 18') define an angle of between 40~ and 70~ causing the front of the rug to exhibit a collar effect about the neck of the horse, said angle being adapted to accommodate at its interior the point of shoulder (16) of the horse, such that the closure (14), and thereby the front (11) of the rug, is maintained in position relative to the point of shoulder (16) while the horse undergoes its normal movements. The horse rug (10) is designed so as to accommodate the structure of the shoulder of the horse and thus obviates the problems of rubbing and interference with the natural movement of the horse observed with conventional horse rugs.

Abstract: An elementary two-stream transport multiplexer provides for the addition of services contained in a transport stream to a pre-existing transport stream.  The elementary multiplexer includes a pair of transport demultiplexers, a processor and a transport remultiplexer. The demultiplexers demultiplex a pair of input transport streams to their constituent service components and service control information tables. The service control information tables are routed to the processor which combines and reconfigures the information within the tables to provide a single set of output service control information tables.  The demultiplexers filter the service components based on the output service control tables. The transport remultiplexer multiplexes the output tables with the filtered streams to provide an output transport stream.

Abstract: On détermine un niveau de lit de boues (18) dans un décanteur pour traitement d'eaux résiduaires (10) en faisant intervenir des réflexions d'impulsions soniques. Il est, de surcroît, possible en utilisant des techniques similaires de déterminer la limpidité des eaux résiduaires. On envoie une impulsion sonique dans les eaux résiduaires et des échos (15) sont produits lorsque l'impulsion (14) rencontre des déséquilibrages d'impédance représentatifs de changements dans la densité de l'eau. Ces échos (15), dont l'atténuation est compensée en fonction de la durée du trajet dans l'eau et la perte d'énergie due aux réflexions de crête antérieures, corrigée, sont traités, par corrélation, afin d'éliminer des signaux aléatoires. Un lit de boues (18) est sélectionné à partir du signal d'écho compensé en fonction des dimensions et de l'emplacement des crêtes d'écho. On détermine, de surcroît, la limpidité en fonction de la zone sous signal d'écho entre deux points correspondant à des niveaux prédéfinis dans la cuve du décanteur (10).
