Patent CA-2171056-A1 (CA)
Title: Conveyor-displacing system and method for mining operation
Inventor: WUESTEN KLAUS
IPC: B65G41/00
Filed: 1996-03-05
Abstract: A bulk conveyor system has a longitudinally extending conveyor belt, devices at the ends for tensioning and relaxing the belt and for advancing the belt, a carriage movable along the belt between the ends, and a transverse conveyor cooperating with the belt, mounted on the carriage, and extending from the belt to a pickup/deposition location.  This conveyor is laterally shifted through a predetermined turnover distance by first  displacing the carriage longitudinally along the belt from one of the ends to the other end while lifting the belt and deflecting it trans-versely at the carriage along an S-path through the turnover distance thereby leaving the belt offset transversely at the other end by the turnover distance from the one end.  Then the belt is arrested and transversely shifted at the other end of the belt by the carriage through twice the turnover distance.  The belt is then relaxed and the device at the other end is shifted transversely by the carriage through twice the turnover distance. the belt is then retensioned and its advance is restarted while the carriage is displaced longitudinally along the belt from the other end to the one end while lifting the belt and deflecting it transversely along an S-path through the turnover distance.  Then the belt is relaxed, arrested, and transversely shifted with the end device at the one end by means of the carriage through a distance equal to twice the turnover distance.  Thereafter these steps are repeated sequentially.

Patent CA-2171476-A1 (CA)
Title: Reduced misting oven cleaner
Inventor: LENTSCH STEVEN E
IPC: C11D1/38
Filed: 1994-08-04
Abstract: Spray-on cleaners that can be delivered by pump or pressurized gas aerosol spray head have been known to cause respiratory distress in the form of a chocking mist. The chocking mist associated with aerosol use can be reduced or eliminated by formulating surface cleaning compositions that can be dispensed through a spray head resulting in an aerosol or mist droplet having a mean particle size greater than about 200 µm. We have found that typical spray-on cleaners have a mean particle size less than about 175 ~,m and, depending on the concentration and degree of irritation of strong base or strong acid components, can cause severe respiratory distress. Preferred thickeners have been found for use in the non-chocking aerosol or mist compositions.

Patent CA-2177352-A1 (CA)
Inventor: TANAKA RYOICHI
IPC: F23L15/02
Filed: 1994-12-01
Abstract: The present invention provides a regenerative heat exchange system which performs heat exchange by alternately passing combustion exhaust gas as high-temperature fluid and combustion air as low-temperature fluid through a fixed regenerator, and a regenerative burner which carries out combustion using preheated air having a high temperature which is obtained by the regenerative heat exchange system. The regenerative heat exchange system comprises: a permeable regenerator  1 partitioned into three or more chambers in the circumferential direction; double-pipe outlet/inlet means 6 partitioned into a supply chamber 6a and an exhaust chamber 6b: and changeover means 3 which isolates the regenerator 1 from the outlet/inlet means 6, and by which the regenerator 1 selectively communicates with the outlet/inlet means 6 by a supply communicating hole 5 and an exhaust communicating hole 4 which are provided with such a positional relation that the supply communicating hole 5 and the exhaust communicating hole 4 do not simultaneously exist in any of partitioned chambers 9, 10 and 11 of the regenerator 1 and a vacant chamber 10 through which the fluid does not flow is formed to at least one position between the chamber through which the exhaust gas flows and the chamber 12 through which the air flows. Further, the regenerative burner is constituted by providing to the regenerative heat exchange system a fuel nozzle 31 piercing through the center thereof so that fuel is continuously injected while the high-temperature combustion air is injected from the regenerator around the fuel. Also, a heat exchange system in which a flowing direction of fluid does not change can be realized by providing outlet/inlet means 6 and changeover means in front of and at the rear of the regenerator 1 without using the fuel nozzle 31.

Title: Adaptive filter with disabling circuit for fast tap weight convergence
Inventor: IKEDA SHIGEJI
IPC: H03H21/00
Filed: 1997-02-27
Abstract: An input signal is supplied to a tapped-delay line adaptive filter to produce tap signals which are equally divided into groups. The tap signals are selectively coupled on a per group basis through a switch to coefficient generators where tap-weight coefficients are produced. The selected tap signals are weighted respectively by the coefficients and summed together to produce a correction signal, which is combined with an output signal which is a replica of the input signal. The coefficients are updated with a residual error of the correction signal. Using the coefficients, the hopping order for selecting a tap group and the dwell time of the tap group are determined. Total power of the selected tap signals is monitored. When the monitored power is lower than a threshold value, the determination of the hopping order and dwell time is disabled and the residual error is nullified for fast convergence.
