A second quantity of bits is used for coding one or more pixels of a second subband image signal. This second quantity of bits comprises one or more bits of the first quantity not used in coding pixels of the first subband image signal. One or more pixels of the second subband image signal are coded using one or more of the second quantity of bits. The second subband imagesignal reflects image object motion information of the color component of the image signal sequence. A third quantity of bits is provided for use in coding one or more pixels of a third subband image signal. The third quantity of bits comprises one or more bits not used in coding either the first or second subband image signals.

Granted: 2001-08-21
Abstract: A method of measuring the inner diameter of a pipe, includes the steps of continuously transmitting electric waves in a predetermined frequency band from an antenna of a transmitter located inside of the pipe to be inspected, receiving the electric waves by an antenna of a receiver located inside the pipe, the antenna of the reciver being spaced apart from the antenna of the transmitter by a predetermined distance, detecting a frequency at a change point where an intensity of the received electric wave changes greatly, substituting the frequency at the change point into a formula: d=c/1.706f (where d is the inner diameter of the pipe, c is the velocity of light, end f is the frequency of the change point) which shows the relation between the inner diameter of the pipe and the frequency to obtain a minimum inner diameter of the pipe.

Title: Explosive powder charge operating setting tool (ii)
Inventor: JOCHUM PETER
IPC: B25C1/14
Filed: 1994-04-19
Granted: 2001-04-17
Abstract: An explosive powder charge operated setting tool contains a channel (7) located between an inner piston guide (2) for a piston (1) and an outer housing part (6). At the rear end of the tool, the channel (7) continues in a carrier (3) and can be in communication with a cartridge receptacle (4) in the carrier (3).      In its front region, the channel (7) is connected via a first opening (2c) in the piston guide (2) with a guide bore (2a) for the piston (1). Towards the rear end of the channel (7) there is a valve arrangement for forming a propellant gas storage space connected through the first opening (2c) to the guide bore (2a).      Propellant gases within the storage space are compressed by the piston (1) driven in the setting direction and, after completion of the driving or setting procedure, serve to return the piston (1) back into its rear starting position by expansion of the storage space gases. After the driving operation, a second opening (3a) communicating with the ambient atmosphere vents the space rearwardly of the piston (1) so that the piston (1) can move without interference back into the rear starting position and, in addition, any residual gases can escape through the second opening into the ambient atmosphere.

Patent CA-2153186-C (CA)
Inventor: SENSENIG DARRYL L
IPC: E04B1/86
Filed: 1995-07-04
Granted: 2000-12-26
Abstract: This invention describes two products both with a plain, fine textured, nonperforated surface visual consisting of a fiberboard substrate with or without a laminated porous nonwoven scrim and then a finished painted surface. The finished painted surface decorates or finishes the board, but most important, must remain acoustically transparent to retain the sound absorption properties of the fiberboard prior to painting. The fiberboard substrate is made to be porous or modified with hole perforations to cause it to be a good sound absorber. If the fiberboard substrate is sufficiently porous without hole perforations, then the sprayable, high solids, porous paint can be directly applied. If hole perforations are used to improve the sound absorption properties of the board substrate, then a porous, nonwoven scrim is attached and painted using the same high solids porous paint. This painted scrim must be sufficiently optically opaque to hide the hole punched board, yet sufficiently open to render it acoustically transparent.
Patent CA-2162745-C (CA)
Inventor: JONES RICHARD EVAN
IPC: B65D65/28
Filed: 1995-11-14
Granted: 2005-08-23
Abstract: Improved detaching of perforated roll products of paper or nonwovens is achieved by selectively reducing strength of the sheet along the perforation line at the edges of the sheet. This is achieved by lowering the bonded length (the sum total of the distance between perforations) at the edges of the sheet relative to that within the central portion of the sheets. Greater bonded lengths in the middle of the sheet enable the sheet to pass through converting operations with minimal breaks, while having lower bonded lengths at the outer edges allows the user more easily to start a tear in the sheet at the perforation and to reduce the number of "ears" left on the roll as a result of detaching.

The removable shoulder (4) makes the nut (5) and shoulder replaceable, and makes possible an additional shoulder (10) on the tube connecting end of the removable-shoulder lug (9) to keep the nut (5) from slipping onto the tube (11).
