Title: Low energy fuse
Inventor: NOBLE ALAN
IPC: C06C5/04
Filed: 1991-03-12
Abstract: In a low energy fuse, the reactive composition on the inner wall of the tubing is substantially free of a metal fuel or quasi metal fuel and comprises a particulate secondary high explosive and a gas generating non-explosive particulate solid selected from barium peroxide, barium nitrate, potassium permanganate, potassium chloride or sodium azide.

Title: Navigation system and method therefor
Inventor: TSUYUKI TOSHIO
IPC: G08G1/0969
Filed: 1990-08-21
Abstract: A navigation apparatus and method designed chiefly for the drivers and also for pedestrians when no such instrument as a distance sensor or a bearing sensor is used. Upon receipt of data related to the passage along which one is now traveling, such as signals from transmitters installed along the passage, electromagnetic waves from an artificial satellite, or based on the distance sensor and bearing sensor, or upon receipt of information input by the user, the apparatus displays what would happen if one proceeds the passage without turning right or left or what would happen if one proceeds a predetermined lane. When a target is set, the apparatus displays both the target and the lane to travel, and further displays the passage leading to the target as well as a proper and suitable passage that leads from a major passage to the target. The data of passage are retrieved by attaching group code and common code to the links. <IMAGE>

Patent CA-2070762-A1 (CA)
Inventor: HINDLE PETER H
IPC: G01N21/86
Filed: 1992-06-09
Abstract: A sampling system includes a plurality of sensing means (3) mounted on one or more beams (2) which reciprocate, over a moving web  (1)  of material.     The sensing zones of adjacent sensing means (3) trace out scanning paths which periodically overlap in a sampling region.    One of the sensing means  (primary)  scans over a known reference to update its calibration periodically or continuously and this is  transferred to the other  sensing means  (secondary) effectively  via  the  travelling  material  (due  to  the overlap).    Calibration is performed by signal processing means, storing and comparing monitoring signal levels or corresponding digital values derived at positions of overlap and making computations for the purpose of calibration. With sufficient overlap of the scanning paths any one of the sensors can be made redundant.     Alternatives include sensing means which move relative to other sensing means as well as rotary arrangements.

Patent CA-2085842-A1 (CA)
Title: Neural network-based speech token recognition system and method
Inventor: COLE RONALD A
IPC: G10L15/16
Filed: 1992-12-18
Abstract: Improved system and method for speaker-independent speech token recognition are described.  The system is neural network-based and involves processing a sequence of spoken utterances, e.g. separately articulated letters of a name, to identify the same based upon a highest probability match of each utterance with learned speech tokens, e.g. the letters of the English language alphabet, and based upon a highest probability match of the uttered sequence with a defined utterance library, e.g. a list of names.          First, the spoken utterance is digitized or captured and processed into a spectral representation.  Second, discrete time frames of the spectral representation are classified phonetically using the spectral coefficients.  Third, the time-frame outputs are used by a modified Viterbi search to locate segment boundaries, near which such segment boundaries lies the information that is needed to discriminate  letters.     Fourth,  the  segmented  or  bounded representation  is  reclassified  using  such  information  into individual hypothesized letters.  Fifth, successive, hypothesized letter scores are analyzed to obtain a high probability match with a spelled word within the utterance library.  The system and method comprehend finer distinctions near points of interest used to discriminate difficult-to-recognize letter pair differences such as M/N, B/D, etc.  The system is described in the context of phone line reception of names spelled by remote users.

Patent CA-2089942-A1 (CA)
Inventor: OBATA KEN
IPC: H02G11/00
Filed: 1993-02-19
Abstract: A transmission device is equipped with a flat cable (11) which has a winding direction reversal section (11a) at the middle, and three dummy cables (21A through 21C) which are wrapped over the flat cable, the winding direction reversal sections (11a and 21a through 21c) of the flat cable and dummy cables being arranged in the circumferential direction at approximately equal intervals. The winding direction reversal sections which produce elastic reaction forces are distributed in the circumferential direction at approximately equal intervals, and hence the slack of the flat cable is suppressed when an inner case or an outer case performs reciprocal rotation, thus securely preventing troubles caused by the slack in the flat cable, whereby the possible case revolution number can be increased with a shorter flat cable, and the operation stability of the transmission device can be improved.

Title: Converter assembly for converting a drive-wheel tractor to a track-driven tractor
Inventor: CHRISTIANSON PETER J
IPC: B62D49/06
Filed: 1993-03-24
Abstract: ABSTRACT    A   converter   assembly   for   converting   a drive-wheel-driven  tractor  into a track-driven tractor, the  assembly  having  its  frame  separate  and unattached relative to the frame of the tractor and constructed and arranged,   together  with  a  continuous  track,  to  be positioned beneath the drive-wheel of  the tractor,  and within  the  track,  in  cooperating  position  with  the drive-wheel   and   track,   to   effectively   extend   the ground-engaging  area  of  the  tractor.     A  pair  of transversely  spaced,  relatively  light,  plate  members rotatably mount a pair of idler wheels, one ahead and one behind  the  drive-wheel  within  the  track.    A  pair  of alignment rollers are also rotatably mounted between the plate members in engaging and aligning relation ahead and behind the drive-wheel, whereby the converter assembly is maintained in aligned relation with the drive-wheel, and some of the weight is transferred from the drive-wheel, through the alignment rollers and plate members, to the idler rollers.  The plate members permit easy application of the converter  assembly to,  or  withdrawal  from,  the drive-wheel by merely jacking the latter into an elevated position and applying or removing, as the case may be, the converter  assembly  and  track  by  merely  removing  the outside  plate  member  before  applying  or  removing  the assembly form the drive-wheel, and re-applying same after the lower portion of the drive-wheel is extended into the track and assembly or is removed therefrom, as the case may  be.    The  entire  converter  assembly  is  otherwise entirely unattached relative to the frame of the tractor.

IPC: B26B9/02
Filed: 1993-04-23
Abstract: ABSTRACT       The  invention  relates  to  knife  blades  and  their methods of production.  Whilst it has long been known that the surface  hardness  and  wear  resistant  properties  of  metal objects  can be enhanced by a hard surface provided  on  them, the  effective employment of this in relation to knife  blades has proved difficult to achieve.   The object of the invention is  to  provide a knife blade with a cutting edge of a  harder material than the body of the blade,  and the objective is met by a construction comprising  a v-shaped cutting edge  formed on  a blank  and such that the cutting tip lies  substantially centrally  of the width of the blank characterised in that one side  face  of the v-shaped cutting edge is  provided with  a coating  of a material harder than the material of the  blank, the  actual  cutting  edge being formed wholly of  the  harder material,  and the coating having a columnar crystal structure that  extends  away from the surface of the blank and  to  the outer face of the coating.
