Patent CA-2306309-A1 (CA)
Title: Harvesting machine
Inventor: CLAUSS STEFFEN
IPC: A01F29/10
Filed: 2000-04-20
Abstract: A harvesting machine includes a crop intake arrangement including either a reel or a crop hold down which operate to aid in the advancement of harvested crop into the machine for further processing. In the event of a jam or the presence of metal occurring, the crop intake arrangement may be operated in reverse so as to expel the jam and/or sensed metal. An actuator is provided for moving the reel or crop hold down between non-operating and operating positions and a first sensor for sensing a jam condition and/or the presence of metal is provided which sends a signal when such a condition exists, this signal being used to effect automatic operation of said actuator so as to move the reel or hold down to a non-operating position so as not to interfere with the expulsion of the jam and/or metal. Other controls are provided and other parameters are sensed for delaying and/or overriding the automatic positioning of the reel or crop hold down in their non-operating position. One such parameter is provided by a timing device which prevents automatic positioning of the reel or crop hold down when the signal indicating a jam or the presence of metal does not endure for a pre-selected time interval. Another parameter is provided by a sensing device which determines whether or not the machine is traveling in the forward direction.  If it is, after a jam or the presence of metal is sensed, then a signal is issued which causes the reel and/or hold down to be returned to its operating position.

Title: Use of a membrane reactor for hydrogen production via the direct cracking of hydrocarbons
Inventor: AMIRIDIS MICHAEL D
IPC: C01B3/50
Filed: 1999-02-19
Abstract: A process for producting substantially pure hydrogen by contacting a stream of a hydrocarbon gas with a nickel containing catalyst in a membrane reactor. The membrane reactor combines a hydrogen permeable membrane and a catalyst capable of producing hydrogen via the direct cracking of hydrocarbons. The stream of a hydrocarbon gas is contacted with the catalyst at a temperature in the range of about 400 to 900 ~C which results in the conversion of the gas to substantially pure hydrogen, which selectively permeates through the membrane wall.

Title: Method and system for supporting wireless communications within an internetwork
Inventor: KORPI MARKKU
IPC: H04Q7/24
Filed: 1999-02-22
Abstract: A system and method for supporting communications among multiple intercon-nected networks (10, 12, 13, 14) include assigning multiple dynamic telephony addresses to each wireless communication device (34) that registers in more than one network. The networks assign the addresses independently of each other.  When an incoming call is directed to a particular wireless device via a first network, if the wireless device is beyond the transmission range of the first network, a locate-wireless-communication-device message may be single-cast, multicast or broadcast to remote networks, with instructions to return dynamic telephony addresses assigned to the device. While the telephony addresses are different in each network, each wireless device is associated with a device identifier that is universally applied in the internetwork.  Upon receiving a telephony address from a remote network, the address is stored in local memory at the first network, thereby allowing access for subsequent incoming calls.

Title: Hapten-carrier conjugates for treating and preventing nicotine addiction
Inventor: FATTOM ALI IBRAHIM
IPC: A61K47/48
Filed: 1999-12-01
Abstract: Novel hapten-carrier conjugates are capable of inducing the production of antibodies, in vivo, that specifically bind to nicotine. These conjugates comprise a nicotine hapten conjugated to an immunogenic carrier protein. The  novel conjugates preserve the chirality of nicotine in its native (S)-(-) state, and have good stability properties. The conjugates are useful in formulating vaccines for active immunization, that are used to prevent and treat nicotine addiction. The antibodies raised in response to the nicotine hapten-carrier conjugate are used for passive immunization. These antibodies  are administered for prevention and treatment of nicotine addiction.
