Title: Rotary log debarker with improved air management system
Inventor: POUSETTE RONALD D
IPC: B27L1/08
Filed: 1992-04-24
Granted: 1995-08-08
Abstract: An air-seal, air-cell rotary-ring-type log debarker which is capable of operating in two different operating modes. In one operating mode, the air seal is nonpressurized, and debarking tools in the debarker are under the actuation control solely of pressure-isolated charged air cells which are carried on the rotary ring in the debarker. In another operating mode, the seal between the rotor and stator is pressurized to allow fluid communication between the two, and tool actuation is under the combined control of the ring-carried air cells and of an external source of seletively variable fluid pressure.

Patent CA-2072535-C (CA)
Title: Equalizer for optically transmitted information signals
Inventor: HEIDEMANN ROLF
IPC: H04B10/2507
Filed: 1992-06-26
Granted: 1998-10-20
Abstract: To compensate for nonlinear signal distortions in analog optical communication transmission systems, caused by laser chirps and the chromatic dispersion of the optical fiber, an equalizer in the form of an LC component is known, whose capacitance is formed by a variable capacitance diode.  However, the known equalizer functions only when the capacitance has the proper polarity, which cannot be predicted because of possible polarity inversion during signal transmission.            According to the invention, the variable capacitance diode (C,) has another variable capacitance diode (Cb), with the opposite polarity, connected in parallel, and is equally biased in the high-resistance direction.  By adjusting the bias voltage of both capacitances, it can be achieved that one of the two variable capacitance diodes takes over the equalization function, and the other is practically inoperative.            Further developments of this solution concern keeping the frequency response constant during adjustment of the equalization, by means of a capacitance connected in parallel to the variable capacitance diodes (Ca, Cb), and the equalization of large bandwidth signals by an LC chain circuit with LC components according to the invention.

Title: Path testing and/or monitoring within a multiple node telecommunication system
Inventor: CHENG YING
IPC: H04L12/26
Filed: 1994-01-24
Granted: 1997-10-21
Abstract: A multiple node telecommunication system path identification technique enabling expedited path testing and/or monitoring, and providing rapid confirmation upon completion of a successful testing and/or monitoring function. The technique eliminates erroneous system alarms arising from a properly transmitted PID arriving at a given node prior to the receipt at that node of the correct PID from a system controller. This is accomplished by employing a memory at each system node capable of storing the most recent PID sent to the node by the system controller, the previous PID sent to the node by the system controller, and the PID received from another system node, or from a transmitter linked to a system transmission path. Each of the nodes within the telecommunication system facilitating the technique is further adapted to accept a PID received via a transmission path without triggering an alarm, if that received PID matches either the most recent or previous PIDs received from the system controller. The nodes are also configured to tolerate a mismatch between a PID received via a transmission path and the stored PIDs received from the system controller for a specified period of time before initiating an alarm, so that if the mismatch may be reconciled if it is merely an erroneous condition brought about by a delay incommunication between the node and the system controller.

Title: Carbonyl sulphide fumigant and method of fumigation
Inventor: BANKS HENRY JONATHAN
IPC: A01N59/04
Filed: 1993-01-15
Granted: 2003-04-29
Abstract: The gaseous chemical compound, carbonyl sulphide, has hitherto been unknown as a fumigant for the control of insects and mites. Experiments have shown conclusively that carbonyl sulphide can be used as such a fumigant, with fumigation propert-ies comparable to those of phosphine and methyl bromide. The effectiveness of carbonyl sulphide against insects (both adult and immature stages), mites, termites and moulds is demonstrated. In addition, its low absorption by grain, lower flammability than phosphine, lack of influence on seed germination, and apparent environmental safety make carbonyl sulphide particularly bene-ficial as a fumigant of stored grain. It may also be used to fumigate other stored produce (including perishable foodstuff), soil, timber and spaces (such as buildings) and any material likely to be infested by insects or mites, ar act as a source of such infesta-tion.
