Abstract: A distance measuring device for use with a reel mounted on a fishing rod, has a series of electrically conductive portions spaced from one another along the length of a line carried by and unwound from the reel. A conductive sensor is adapted to be fixedly mounted on the rod along the path of movement of the line such that an electrical circuit is completed each time one of the conductive portions of the line passes by the sensor. The number of tires the electrical circuit is completed is counted, and a calculator coupled to the counting means converts the counted number of completed circuits to a proportional distance measurement.

Patent CA-2350951-A1 (CA)
Title: Crop material processor
Inventor: HRUSKA KEVIN
IPC: A01F29/02
Filed: 1999-09-17
Abstract: A baled crop material processor for disintegrating baled crop material comprising a container, a disintegrator, a discharge opening and means for manipulating the crop material for disintegration by the disintegrator. The container, receives and contains the crop material. The disintegrator comprises a flail roller that is mounted within the container and has a number of flails pivotally mounted about it. The flail roller rotates about its own longitudinal axis in either a clockwise or counter-clockwise direction. The discharge opening is at the bottom of one of the side walls to discharge the disintegrated crop material either to the left or to the right of the processor and in a bidirectional processor, the operator may alternate between sides. The manipulation means comprises manipulator rollers having paddles positioned at an angle to the length of the roller to rotate the crop material without substantially breaking the crop material apart. The paddles are channel shaped with outwardly curved ends to grasp the baled crop material for rotation and then to pull out of the crop material due to the curved end as the roller is rotated. Further, the angled paddles guide the crop material longitudinally toward the centre of the crop material processor away from the front and back walls. Moreover, the sidewalls of the container are shaped to have a protrusion projecting into the container in close proximity to the paddles, a spacing below the protrusion to prevent the accumulation of loose material, and outwardly sloped wall portions above the protrusion.

Patent CA-2353053-A1 (CA)
Inventor: DOETSCH PETER
IPC: F04B1/20
Filed: 2001-07-13
Abstract: A marine steering system operable in either power steering or manual hydraulic modes. The system employs a modified helm pump having a single rotatable input shaft connectable to a steering wheel and dual hydraulic and electronic output. An encoder, such as an optical incremental encoder or hall effect device, is mechanically coupled to the input shaft for generating an electronic steering control signal representative of the change in position of the steering wheel. In the power steering mode, the electronic steering signal is processed by an amplifier controlling the operation of an auxiliary pumpset connected to the rudder steering cylinder. A bypass manifold disposed between the helm pump and the steering cylinder disables the hydraulic steering system in the power steering mode. In the event of power failure, the bypass manifold valves are opened and the system automatically switches to manual hydraulic steering.

Title: Indicateurs de suivi thermique
Inventor: TESTER RICHARD
IPC: G01K3/04
Filed: 2000-02-10
Abstract: L'invention concerne un indicateur de suivi thermique destiné à être fixé sur des marchandises. Un changement de phase lié à la température dans un matériau de l'indicateur donne une indication sur l'occurrence d'une température élevée. En configuration préférée, un colorant hydrosoluble et insoluble dans les lipides est immobilisé dans un lipide dont le point de fusion correspond à une température particulière et dont tous les éléments constitutifs sont à base de matière comestible. A la fusion, le colorant se dissout dans l'eau présente dans une phase secondaire ou les marchandises elles-mêmes donnent une indication visuelle. Selon une autre configuration, un premier réactif dans un lipide solide et un second réactif maintenu dans une phase secondaire font que la fusion du lipide permet au premier réactif de réagir avec le second réactif, donnant ainsi une indication d'occurrence de température élevée. L'invention concerne également des configurations dans lesquelles les indications sont diachroniques.

IPC: H04N5/44
Filed: 2002-01-18
Abstract: A home entertainment system has a switching matrix having supply ports that are connected to a plurality of TV tuners and at least one video camera.  Each TV tuner demodulates a high frequency carrier signal to provide a specific channel to a supply port. Control signals that change the channel output of each TV  tuner are transmitted upstream from the supply port to a corresponding TV tuner. The switching matrix has consumer ports that connect to terminals with consumer devices such as TV monitors located in different rooms of the home, each terminal receiving a signal of baseband frequency (no demodulation required) that may represent a television channel or a camera view and each terminal having a control that delivers signals to the consumer port to select a TV channel or select the camera. The switching matrix enables different ports to be coupled together, so that, for example, a camera in baby's room can be coupled to a television monitor in another room. All of the TV tuners and the switching matrix are located in the hub that lies in one room of a home, while the monitors are in different rooms, and the distribution of signals around the system takes place at baseband frequencies.

Abstract: An interface (52) is provided between a satellite telephone system (4) and a cellular telephone system (5) for allowing calls to a user's cellular telephone to be diverted to a satellite telephone (25) when the user is unable to use his cellular telephone, for example when on board an aeroplane (2) fitted with a satellite telephone system (20). The user inserts a card (which may be the SIM of his mobile phone, or a card compatible with existing satellite telephone equipment) into a suitable reader in the satellite telephone (20), which causes the satellite ground station's card verification system (42) to connect to a host cellular network (50). The host cellular network has an interface unit (52) which emulates the operation of a normal base station, so that the host cellular system (50) acts as if the mobile user's terminal is roaming on the host network, but is currently "busy". The interface (52) also resets the user's existing call diversion instructions so that when the host cellular system (5) receives a busy tone frome the base station emulator (52), it routes calls to the directory number of the terminal (20).

Abstract: A can lid structure, with an opening tab providing improved practicability, enhanced opening function and improved sanitariness, is disclosed. This can lid structure is preferably used with easy open cans with one-touch type opening means, or with a so-called "stay-on tab". In the above can lid structure, an opening tab (30), locked to a can lid using a rivet (24), is levered up by a user so as to break the seal of an opening piece (22) along a depressed seam (21) on the can lid when it is necessary to open the lid prior to emptying a can (10). In order to open the can lid, the free end portion (31) of the tab 30 is primarily raised up from the top surface (20) of the can lid while forming an appropriate gap between the tab (30) and the can lid by pressing the tab (30) downwardly by a finger. The tab (30) is, thereafter, levered up to break the seal of the opening piece (22) along the depressed seam (21). The above object is accomplished by a thumb pushing part (36), a thumb-operable resilient bulge (33), and/or a depressed linear portion (38) in the form of a groove, respectively formed on predetermined positions of the tab (30). This can lid structure thus accomplishes a desired sanitariness, operational convenience and operational reliability of cans (10).
