Patent CA-2160375-A1 (CA)
Title: Improvements in or relating to continuously-variable-ratio transmissions
Inventor: GREENWOOD CHRISTOPHER JOHN
IPC: F16H37/06
Filed: 1994-04-14
Abstract: A continuously-variable ratio transmission comprising a ratio-varying unit ("variator"), and an epicyclic unit having three outputs arranged concentrically. Two of those outputs are connected respectively in fixed ratio to opposite ends of die variator, so that as the variator ratio changes, the speed of one of these outputs always rises and that of the other falls. These two outputs are also connected by appropriate gearing and clutches to die CVT output shaft. Successive regimes of operation, so extending the overall ratio range of die CVT, are obtained by alternatively connecting each of the two epicyclic outputs to the CVT output. Ratios and other parameters are chosen so that regime changes are synchronous.

Title: Working Chamber for an Electrically Operated Domestic Kitchen Appliance
Inventor: REBORDOSA ANTONIO
IPC: A47J43/07
Filed: 1994-06-21
Abstract: The invention is directed to a working bowl  (1)  for an electrically powered domestic kitchen appliance, in which, among other tools, a relatively fast-spinn;ng, blade-like working tool (25) is to be able to rotate, wherein the inner wall (3) takes the form of a substantially regular polygon having at least five and preferably fifteen sides (4).   The axis of rotation of the blade-like tool (25) lies at the center (20) of the circumcircle (21) of the respective polygon.  As a result, food items such as parsley,  onions,  etc.  are fed back to the blade particularly effectively,  thereby enabling the food to be comminuted espe-cially rapidly.

Title: Method for recognizing a spoken word in the presence of interfering speech
Inventor: SCHALK THOMAS B
IPC: G10L21/02
Filed: 1994-08-15
Abstract: A method for recognizing a spoken word in the presence of interfering speech beings by echo-cancelling the voice prompt and any detected speech signal to produce a residual signal (60).  Portions of the residual signal that have been most recently echo-cancelled are then continuously stored in a buffer (62).  The energy in the residual signal is also continuously processed to determine onset of the spoken word (64).  Upon detection of word onset, the portion of the residual signal then currently in the buffer is retained, the voice prompt is terminated, and the recognizer begins realtime recognition of subsequent portions of the residual signal (66).  Upon detection of word completion (68), the method retrieves the portion of the residual that was retained in the buffer upon detection of word onset (70) and performs recognition of that portion (72).

Title: Filter apparatus
Inventor: JOHNSON RONALD L JR
IPC: B01D33/048
Filed: 1996-05-31
Abstract: An improved filter apparatus (10) for removing debris from a free flowing water system (100) is described The apparatus has a rail (12) which is mounted adjacent the water supply intake opening (102) and extends upward from the floor (100A) of the water system at an incline. The apparatus has a continuous belt (36) made of chain links (38) and connectors (44) which mounts around an upper sprocket cylinder (26) at the top (12B) of the rail and around a lower sprocket cylinder (32) spaced above the bottom (12A) of the rail. The chain links allow for openings (42) in the belt which enable the belt to collect debris from the water flowing through the belt. The connectors have lifters (50) which move the debris collected on the front side 36A of the belt. The belt is loosely mounted around the sprocket cylinders which allows the lifters to tilt and dump any debris of excess weight back into the water system. The size and length of the connectors and the lifters is varied in order to change the weight limit at which the lifters tilt. The belt is moved upward by a motor (54) which rotates the upper sprocket cylinder. As the belt moves upward, the debris collected on the belt and by the lifters is moved out of the water system toward the top of the rail. As the belt moves over the upper sprocket cylinder, the upper sprocket teeth (28A) of the upper sprockets (28) extend through the openings of the belt loosening the debris trapped on the front side of the belt which falls into the collection trough (104). The upper sprocket teeth also scrape the sides of the openings in order to remove all debris and built up deposits. As the connectors move over the first sprocket cylinder, the lifters are turned upside down which dumps the debris into the trough beneath the top of the rail. A water pressure jet (60) sprays the remaining debris from the belt as the belt moves downward back into the water system.

Abstract: Soupape linéaire à gaine (11) comportant une plate-forme (33) et un couvercle (21) lui étant adapté. La plate-forme (33) de soupape peut comporter un canal d'entrée (39) et un canal de sortie (45) amenant un liquide dans la soupape et hors de celle-ci. Une membrane d'élastomère (29) est maintenue sous tension entre le couvercle (21) et la plate-forme (33) de manière à commander le débit entre les canaux. Le couvercle (21) comporte à sa surface (22) une zone d'expansion contiguë à la membrane (29) et située entre l'entrée (39) et la sortie (45). Le liquide ne peut traverser la soupape que s'il est sous une pression suffisante pour repousser la membrane (29) dans la zone d'expansion, ce qui crée entre la membrane (29) et la plate-forme (33) de la soupape un passage reliant l'entrée (39) à la sortie (45). La disparition de la pression du liquide amène la membrane (29) à fermer l'entrée (39) et la sortie (45) et à empêcher tout écoulement entre elles.
