Patent CA-2149113-A1 (CA)
Title: Reversible plough
Inventor: TOPHAM PETER DOUGLAS TEMPLE
IPC: A01B15/14
Filed: 1993-08-19
Abstract: A reversible plough is disclosed in which a plurality of plough bodies are pivotally supported from a beam (8) which itself is inclinable in opposite directions relative to the direction of movement of the plough, together with adjustment of the plough bodies, so as to permit the plough to produce right-hand or left-hand turning of the soil as required, to enable the plough to go back and forth producing similar furrows across a field. A particular linkage is provided in order, automatically, to adjust the direction of extent of the plough bodies, relative to the beam (8), the direction of extent of the plough bodies normally being at a slight angle to the direction of movement of the plough in order to compensate for the asymmetric pull of the tractor on the inclined beam (8). As disclosed, the plough bodies themselves comprise rotary-inversion-wheel-type ploughing discs, the inclination of the axis of rotation of the ploughing discs being inclined to opposite sides of the length of the plough body, depending on whether a left-hand or right-hand furrow is required.

Inventor: SMITH ROBERT C
IPC: A61B1/00
Filed: 1995-07-18
Abstract: Valve assembly for sealed reception of an elongated object includes a valve body having at least one opening configured and dimensioned to permit entry of an elongated object and defining a central longitudinal axis, an elongated seal member formed of a resilient material and defining an aperture in general alignment with the opening of the valve body whereby the aperture is configured and dimensioned such that insertion of the object into the aperture causes the resilient material defining the aperture to resiliently engage the outer surface of the object in a substantially fluid flight manner, and at least one elongated guard member disposed within the seal member in supporting contact with the inner surface thereof. The guard member is positioned to engage the elongated object upon at least partial insertion of the elongated object into the valve body. The guard member includes at least a first substantially rigid portion adapted to be displaced relative to the longitudinal axis to facilitate expansion of the aperture of the seal member upon entry of the object therein and a second portion having less rigidity than the first portion of the guard member to enhance passage of the elongated object through the valve body.

Title: A method and a system in a distributed operating system
Inventor: M LOEY JON PAUL
IPC: G06F9/46
Filed: 1994-02-02
Abstract: For establishing two-way communication links between processes in a distributed operative system, the processes are provided with ports through which communication between the processes is performed.  The processes and the ports make possible for the operative system to keep a check on processes having links and to use these links also if the process per se is terminated, and to discover an error in the process and terminate it.  For enabling the operative system to be able to transmit via the links information regarding process or computer drop out and thus be able to propagate this information through the whole chain of linked processes, and to report this information to applications executed in the linked processes in order to enable for these to undertake application specific measures, a code is used which is called at link abortion and communication errors.  The function of this code includes terminating an erroneous process and reporting the error to an error handling code. The first mentioned code is always executing in a process to which an error has been reported.

IPC: B65B57/20
Filed: 1996-04-18
Abstract: A system for sequentially establishing  batches of predetermined numbers of items is disclosed.  The system includes a feeder for continuously dispensing items serially and one at a time.  A counter counts items as they aredispensed by the feeder and emits a batch  control signal  each time a predetermined number of items has been dispensed by the feeder.  An item accumulator/separator separates items fed on a continuous basis into batches. The separator includes a diverter for diverting items forming each succeeding batch to a collection location separated from the location of items in the batchimmediately  preceding each separated batch while maintaining  all items along a flow path from the feeder to a collection station.  The diverter is operative to establish diversion of items of  a succeeding  batch in response to each such batch control signal. A collector is positioned at the collection station for sequentially collecting such batches and maintaining  them in such separated condition.

Patent CA-2177301-A1 (CA)
Inventor: KIMURA EIICHI
IPC: F02N15/02
Filed: 1996-05-24
Abstract: In an engine starter comprising a pinion slidably fitted on the output shaft for driving a ring gear of an engine that is to be started, and a one-way clutch having a first end secured to the pinion and a second end which is engaged by the output shaft via spline means, a compression coil spring is interposed between a stopper secured to the output shaft and an annular shoulder defined in a cylindrical extension of the second end of the one-way clutch. Therefore, even when the pinion is forced into a high speed rotation by the engine which has been started by the engine starter, the pinion simply rotates freely, and no friction is applied to the compression coil spring or the stopper. Also, by receiving the compression coil spring in an annular space defined between the cylindrical extension of the second end of the one-way clutch and the output shaft, the compression coil spring can be protected from the centrifugal force which acts upon the compression coil spring when the output shaft of the engine starter rotates at an extremely high speed.

Title: Method and Apparatus for Pinch Perforating Multi-Ply Web Material
Inventor: SCHULZ GALYN
IPC: B26D7/26
Filed: 1996-10-17
Abstract: A method and apparatus for pinch perforating multi-ply web material to increase the perforation ply bond and/or perforation ply bond retention by pinching the multiple plies of web material together and then perforating the material using an anvil and perforator blade design provided on a perforating apparatus. Specifically, the apparatus comprises a roll mounted contoured perforator blade which cooperates with a beveled anvil to produce perforation ply bonds perpendicular to the length of the multiple plies of web material. The desired anvil/perforator blade interface angle between 0° and 20° is provided by beveling the anvil. A 15° beveled anvil is preferred to provide a 5° anvil/perforator blade interface angle. By pinching and bonding the leading edges and other predetermined points of the multi-ply tissue paper together before cutting, the likelihood of ply separation, missing plies and plymismatch is greatly reduced.
