Granted: 2000-02-08
Abstract: Une sortie A et une sortie B d'un fichier (16) de registres sont reliées chacune à un multiplexeur (18, 20) associé. Chaque multiplexeur comporte à titre d'entrée supplémentaire, un bus (CB00:31) acheminant un résultat provenant d'une unité arithmétique/logique (UAL) (22) par l'intermédiaire d'un décaleur (28) d'UAL. Les sorties des multiplexeurs sont reliées à des entrées A ou B de l'UAL. Chaque multiplexeur est commandé par un comparateur (24, 26) d'adresses de fichier de registres associé. Les comparateurs d'adresses disposent chacun, à titre d'entrée, d'adresses correspondantes de mise à jour et d'accès de fichier de registres A et B. Les comparateurs d'adresses comparent leurs adresses de mise à jour et d'accès de fichier de registres associées, afin de déterminer si le registre du fichier de registres sélectionné pour être sollicité, est égal au registre du fichier de registres sélectionné pour être mis à jour. Si ces deux adresses s'avèrent égales, il est indiqué que le résultat d'une opération de l'UAL, pendant un cycle N d'instructions, est utilisée comme opérande pour une opération d'UAL pendant un cycle N+1. Lorsque cet état est détecté, la sortie du comparateur d'adresses associé permet à l'entrée de sélection correspondante du multiplexeur de transmettre le résultat de l'UAL directement à l'entrée correspondante de l'UAL, contournant ainsi effectivement le fichier de registres.

Patent CA-2073284-C (CA)
Inventor: BOGEMA EDWARD JOHN
IPC: F16H57/00
Filed: 1992-07-07
Granted: 1998-11-03
Abstract: An improved vehicle transmission (10) which substantially reduces the noisy rattle normally produced by interengagement of the input shaft (12) and the input drive gear (14) of the transmission when the engine of the vehicle is operating at idle speed and the transmission is in neutral.  The input shaft (12) and the input drive gear (14) are in constant driven relationship.   In the inventive structure, the interengageable spline teeth (70 and 71) of the input shaft (12) and the input drive gear (14) of the transmission (10) are provided with a greater backlash  (75)  than is normally used.   The intermittent firings of the engine (E) normally cause non-synchronous rotation of the input shaft  (12)  relative to the input drive gear  (14)  with attendant engagement of their respective spline teeth (70 and 71). The increased backlash  (75)  provides greater spacing between the interengaging teeth which substantially eliminates the engagement of the spline teeth and attendant rattle noise.

Abstract: In a hydrocyclone the separation chamber (2) has a cir-cumferential wall (3) provided with at least one turbulence creat-ing member (12), which extends along the circumferential wall and crosses a helical path (10), along which a liquid stream is generated during operation. According to the invention, the turb-ulence creating member is formed by a set-off (12) on the circum-ferential wall (3). The set-off is formed and dimensioned such that said liquid stream substantially looses its contact with the circumferential wall, as the liquid stream passes the set-off. As a result turbulence is created in a layer of the liquid stream situated closest to the circumferential wall, without the liquid stream be-coming any substantial flow component directed inwards in the separation chamber.
