Patent CA-2223635-A1 (CA)
Title: Method of reconditioning used wood
Inventor: BOEHME CHRISTIAN
IPC: B27K3/00
Filed: 1997-05-22
Abstract: The invention relates to a process for separating the surface layer from the core of a piece of wood. During said process, the surface of the piece of wood receives prior mechanical damage, e.g. it is roughened, and subsequently the resultant piece of wood is immersed in water or a water solution until the level of dampness in the surface layer of the wood is at least 30 %. The resultant piece of wood is subsequently steamed at a temperature of from 120 to 160~ Celsius, and the surface layer to be removed is consequently superficially etched to such an extent that it can be detached from the piece of wood in a subsequent stage.

Title: Method for improving the coupling response of a water-bottom seismic sensor
Inventor: GAISER JAMES E
IPC: G01V1/16
Filed: 1998-03-02
Abstract: A receiver consistent deconvolution operator models the damped oscillatory wavetrain that is related to geophone coupling to the water bottom.  The operator is a best-fitting function that endeavors to describe the difference in coupling response between a well-coupled in-line geophone relative to an imperfectly-coupled cross-line geophone.  The operator is applied to the cross-line signals to compensate the signals for the distortion due to imperfect cross-line ground coupling.

Inventor: DUNN JAMES M
IPC: G06F19/00
Filed: 1996-12-12
Abstract: A virtual DNA sequencer combines a plurality of individual DNA sequencers. Samples of DNA or other nucleic acid from subjects are prepared and allocated in real time to particular lanes or sets of lanes in electrophoresis plates of the individual sequencers, with records kept of the allocations. The data resulting from the electrophoresis runs is collected and collated according to the identities of the subjects. The individual sequencers are networked, and each individual sequencer is preferably equipped with a data buffer large enough to accommodate all or substantially all of a data run, thus protecting the virtual sequencer from loss of valuable data in the event that the network is disrupted for some portion of the time of the data run. In this way, a plurality of sequencers is virtually the same as a single sequencer with a very large number of tracks each of which can run for a much longer sequencing run than an individual sequencer.

Filed: 1997-05-22
Abstract: The invention relates to a method and apparatus for channel hopping between mobile stations (MS1-MS3) and a base station (BS1) in a radio communications system. A channel allocation means (211) within the base station (BS1) generates channel hopping sequences that are transmitted via a control channel (SACCH) to hopping sequence lists (204-206) in the mobile stations (MS1-MS3).  The hopping sequences are also transmitted to corresponding hopping sequence lists (201-203) in the base station (BS1). A channel hopping sequence is divided into a number of sequence intervals (Ti) corresponding to the time between two adjacent channel hops within a channel hopping sequence. In the channel allocation means (211) the attenuation (.delta.) of the connections (F1-F3) and the interference (I(channel,t)) of the channels are continuously being observed within each sequence interval (Ti). The channel allocation means (211) generates channel hopping sequences according to the principle that a connection that has poor connection quality will be allocated a channel hopping sequence with channels of high channel quality and connections with successively better connection quality are allocated channel hopping sequence having successively poorer channels.
