Inventor: SLATTERY MICHAEL GERARD
IPC: A01C7/00
Filed: 1996-08-02
Abstract: A ground following opener comprises a support frame (20), a parallelogram arrangement (B, C, D and E) pivotably attached at (D) to the support frame, a tyne shank (14) supported by the parallelogram means at (C, B), and an opener means (10) supported at a free end of said tyne shank (14). The pivot at D is arranged to allow rotational movement of the parallelogram independent of the frame (tripping) so that the opener can pass over the surface of an obstacle in the ground. Furthermore, a ground following means (16) is attached to the tyne or the arm of the parallelogram to which it is attached. A single bias means (32) is pivotably attached at one of its ends to the supportframe (20) and also pivotably attached at its other end to an arm of the parallelogram so that the single bias means urges the opener means into the ground as well as biasing the return of the parallelogram, tyne, ground followerand opener means towards the ground after they have been rotated independent of the frame when the opener passes over the surface of an obstacle in the ground. To assist the operation of the invention the point of pivot of the biasing means to the parallelogram is offset from the axis of the pivotable attachment between arms of the parallelogram.

Abstract: Un procédé de préparation de poudre métallique de cobalt, comprenant : (a) la mise en réaction d'un sel de cobalt soluble avec une solution ou une suspension d'un carbonate ou d'un hydrogénocarbonate de métal alcalin, d'un carbonate ou d'un hydrogénocarbonate de métal alcalino-terreux, d'un carbonate ou d'un hydrogénocarbonate de cobalt, ou d'un carbonate ou d'un hydrogénocarbonate d'ammonium dans une plage de pH comprise entre 5,5 et 6,8 et à une température inférieure à 35 degrés C ; (b) la séparation du produit précipité de carbonate de cobalt de l'étape (a) et le lavage avec de l'eau du produit précipité de carbonate de cobalt jusqu'à ce que la pureté requise soit obtenue et le séchage du carbonate de cobalt lavé ; et (c) la réduction du produit de carbonate de cobalt de l'étape (b) en poudre métallique de cobalt. Les procédés de la technique antérieure mis en oeuvre à des valeurs de pH dans la plage comprise entre 7,0 et 7,4 entraînent la précipitation quantitative des ions Co présents dans la solution. Cela présente toutefois l'inconvénient de réduire l'efficacité avec laquelle le précipité peut être lavé, entraînant ainsi des teneurs accrues en Na, Ca et S dans le produit final. En revanche, le processus conformément à l'invention est mis en ouvre avec la valeur de pH réglée à moins de 6,8. De cette manière, un lavage beaucoup plus efficace du précipité est obtenu et la teneur en impuretés est par conséquent considérablement réduite.

Title: Method and apparatus for generating, recording and transmitting an errorproduct code block having an improved check code arrangement
Inventor: KOJIMA TADASHI
IPC: H03M13/15
Filed: 1996-04-08
Abstract: There is provided a method of processing data for generating an error correction product code block devised so as to maintain the current level of redundancy after the error correcting ability is modified as a result of advancement of simiconductor and data recording/transmission technologies. Unlike any known technique of configuring a Reed-Solomon error correcting product code block of (M+PO)x(N+PI) bytes for an information data of (MxN) bytes, an error correcting product code block data structure is obtained by configuring a (Kx(M+1)x(N+P))-byte Reed-Solomon error correcting product code block for (KxMxN)-byte data, making K variable to consequently make the entire size of the Reed-Solomon error correcting product code block variable. At the same time, the error correcting ability varies in proportion to the value of K without increasing redundancy.

Patent CA-2220209-A1 (CA)
Title: Torque splitting device using hydraulic clutches
Inventor: ASANO TETSUSHI
IPC: F16D48/12
Filed: 1997-11-05
Abstract: An improvement is made to a torque splitting device employing hydraulic clutches so as to avoid any discontinuity in the control even when the properties of the actuating oil such as the pressure and temperature thereof deviate from standard values. For instance, when the oil temperature is low, the target value of the oil pressure for each of the clutches is modified to a lower value. Thus, it becomes possible to make less pronounced any delay in the response of the torque splitting device which may arise due to the sluggishness of the oil as it flow out of the clutch cylinder. The oil pump is typically actuated by a member rotating at a speed proportional to the vehicle speed, and the pressure output of the pump may be inadequate in a low speed range. In such a case, the target value is again reduced so as to reduce any abrupt change in the property of the torque splitting device when the vehicle is accelerated from a low speed. Because the pressure output of the pump normally drops as the oil temperature rises, it is desirable to take into account the oil temperature in this control action as well.
