Patent CA-2166248-A1 (CA)
Inventor: AL-KARMI ABDEL NASER
IPC: G06V30/10
Filed: 1995-12-28
Abstract: A method and apparatus for optical character recognition particularly suitable for cursive and scripted text in one or more of several languages follows the tracings of the script and encodes them as a sequence of directional vectors.  It reads a preprocessed word or sub-word of interconnected characters as a unit and the characters are accepted in a specific language only if all characters in a unit have been recognized by testing against a first set of language-specific rules without leaving a remainder of any vectors in the unit. If there are vectors remaining unused, it moves a character marker to utilize more or fewer vectors for the current sub-word in order to obtain recognition. If the vectors do not form a character in a first language, the invention consults a second set of language-specific rules and follows similar steps to obtain recognition of one or more characters against the second set of language-specific rules. Also disclosed is a computer-usable medium, for example a magnetic or optical storage diskette, containing code means to execute the invention.

Title: Electromagnetic induction heating coil
Inventor: CROFTS DAVID
IPC: H05B6/44
Filed: 1996-01-11
Abstract: Open-sided electromagnetic induction heating coil having overlapping coil sections (20, 21, 22, 23, 24, 25 Fig. 2) which are electrically connected in parallel to one another enabling relatively large coils to be constructed from conveniently bendable narrow copper tubing while keeping the coil impedance low enough for incorporation in a resonant tank circuit at frequencies watched to a remote high-frequency generator so as to minimise power losses in the leads connecting the tank circuit to the generator. Methods of induction heating using the coil, especially in blocking of wiring harnesses, are also described.

Title: Elastic mounting for track pivot pins in caterpillar tracks
Inventor: WIESNER HAGEN HEINZ
IPC: B62D55/21
Filed: 1995-01-25
Abstract: In hinge  tracks with rubber mountings (5) in which rubber-lined tubular steel bushes mount track pivot pins (20), the pin ends are usually provided with screwthreaded projection portions so that the steel bushes (10) are motion-free braced relative to each other and relative to the track pivot pins (20) by means of nuts.  In order to improve  the  useful  life  of  the  rubber  mounting  (5)  and  reduce maintenance,  a rubber-lined spreadable bush (10) with at least one dividing gap (11) is proposed instead of the tubular bush.  The internal width (25) of the bush (10) which is pressed into position is less than the diameter (27) of the track pivot pin (20).  The inserted track pivot pin (20) expands the bush (10) which is pressed into the chain link member (1).  In that case the track pivot pin (20) is braced in the bush (10)  and  is  fixed  in  its longitudinal  direction  by  frictional engagement and in the peripheral direction by frictional engagement and/or positively locking engagement. The screw means for bracing the bushes  (10)  are eliminated and an increase in the rubber mounting surface is achieved by virtue of using the screwthread space of the screwthread arrangement. That affords an increased service life for the rubber mounting in a maintenance-free design configuration.

Title: Device for damping vibration of rotor
Inventor: OKUMA KIYOSHI
IPC: F16F15/315
Filed: 1994-10-13
Abstract: The present invention provides a vibration damping device capable of effectively damping the vibration during the rotation of rotor without disturbing the miniaturization of the peripheral structure of the rotor. The vibration damping device (10) is provided with a support member (20) fixedly secured to a rotor shaft (14) and a vibration damping member (22) nipped between a main mass (12) of the rotor and the support member (20). One axial end surface (26a) of a flange (26) of the support member (20) is positioned generally perpendicular to an axis of the shaft (14). The vibration damping member (22) is made of a visco-elastic material and fixedly connected, respectively, with one axial end surface (12a) of the main mass (12) and with the axial end surface (26a) of the support member (20) arranged in parallel and opposite to the former axial end surface (12a) apart therefrom at a distance. When the vibration occurs during the rotation of the rotor, the vibration damping member (22) nipped between the axial end surfaces (12a) and (26a) deforms in a visco-elastic manner to mitigate and rapidly damp the vibration.

Abstract: A leverage insertion assembly for inserting and removing a carrying pipe from a main pipeline in which a fluid is flowing.  The leverage device includes a hollow positioning pipe in which the carrying pipe is inserted.  The positioning pipe is connected to the main pipeline with a gate valve attached to the positioning pipe designed to open and close the positioning pipe.  Formed on the outer surface of the section of positioning pipe on the side of the gate valve opposite the main pipeline is a spiral cut-out.  Handles are attached to the sides of the carrying pipe positioned inside the positioning pipe and extend through the spiral cut-out.          During operation, the carrying pipe is moved longitudinally inside the positioning pipe when the handles are forced to follow the spiral cut-out. When the carrying pipe has been moved a sufficient distance inside the positioning pipe to clear the gate valve, the gate valve may be closed thereby closing the positioning pipe.  The carrying pipe can then be removed from the positioning pipe.

Abstract: This invention provides a driver attachment for a collated screwstrip in which a slide body is slidable in a housing parallel a longitudinal axis about which drive shaft is rotatable. The slide body has a nose portion. A screw feed activation mechanism coupled between the housing and the slide body translates relative sliding movement and positioning of the slide body relative the housing.
