Patent CA-2260162-A1 (CA)
Title: Self-cleaning air filter assembly
Inventor: VIDOVICH JOHN C
IPC: B01D46/24
Filed: 1999-01-22
Abstract: An air filter and dust collector assembly includes one or more filter elements with an air pervious filter media for collecting particulate material or filter cake on the filter surface. An elongated flexible hose having a free distal end is suspended within the clean air space of the filter element and is fitted for coupling attachment to a source of pressurized air. The filter cleaning hose member preferably has elongated circumferentially spaced slit-like apertures for discharging pressurized air whereby the reaction force of air discharging through the slit-like apertures causes the hose to flail about and impact the filter element. The combined action of the reverse jet airflow and the impact forces exerted on the filter element by the random flailing of the hose member provides effective removal of dust and particulates from the filter media. A manual or automatically controlled valve is operated periodically to discharge pressurized air through the flexible hose.

Inventor: REINHARDT PAUL A
IPC: E21B41/00
Filed: 1999-01-29
Abstract: An apparatus and method for transporting a downhole tool in a borehole. A phase change material such as a shape memory metal is activated to engage the borehole and to transport the tool through the borehole. After the tool has been advanced in the borehole, the phase change material is deactivated to release from the borehole wall, and advances into position to continue the transport process. An extension can be engaged with the phase change material to extend the movement range of the phase change material. The phase change material actuator requires few moving parts and can be integrated with other tool components. The invention can operate in opposite directions within a borehole and can replace wellbore tractors and other locomotive tools.

Patent CA-2263277-A1 (CA)
Inventor: WONG SIU WAH
IPC: H04B7/185
Filed: 1999-03-02
Abstract: In a radio frequency communications system, a data carrier activation method is implemented such that the carrier is switched off when no data is available for transmission. If repeated signalling information is required to be transmitted, only a predetermined number of repeats is transmitted before the carrier is switched off. The data input for transmission are compared with an idle sequence with different bit alignments to detect the presence of idle signalling , and the carrier is switched off if a match is found. When more user data is received, the carrier is switched on and frames (SM) are transmitted in synchronization with the timing of frames (SM) transmitted before the carrier deactivation. After carrier reactivation, a constant power preamble (P) may be transmitted to assist in level control in the transmitter (27; 40).

Title: Copy generation management method, information signal reproducing method, information signal reproducing apparatus, and information signal recording apparatus
Inventor: OGINO AKIRA
IPC: G06F21/10
Filed: 1999-06-09
Abstract: A reproducing method and apparatus includes a system for controlling copy generation by adding a piece of copy control information to an information signal. The reproducing apparatus according to the invention can essentially disable reproduction of information signals from an illegally copied recording medium, and can prevent illicit copying effectively.  Accordingly, a reproducing and/or recording system is provided, in which copy generation of an information signal is controlled through the use of copy control information that is added to the information signal. The copy control information takes on at least one of three possible states, a one-copy allowed state, a more-copy prohibited state and a copy absolutely prohibited state. The system determines an initial copy control state for the signal being reproduced and determines the state of copy control information to be added to the reproduced signal based on at least the initial copy control information. During recording it may be determined that no further copy control information is to be added to the signal.
