Patent CA-2149814-A1 (CA)
Title: Pump oil mister
Inventor: ROCKWOOD ROBERT E
IPC: F04D29/06
Filed: 1995-05-19
Abstract: A  pump   including   a  pump   shaft   bearing lubrication system having a main lubrication chamber and a pair of auxiliary lubrication chambers,  the auxiliary chambers being disposed on opposite sides of said main chamber.  Pump shaft bearing assemblies (single or double row)  are  sandwiched between each auxiliary lubrication chamber  and  the  main  chamber  so  that  each bearing assembly has  its  inner  and outer  sides  simultaneously lubricated  by  fluid  in  the  main  and  corresponding auxiliary   chamber   respectively.      Each   auxiliary lubrication  chamber  is  provided with a pair  of  fluid passageways interfacing the auxiliary and main chambers so that the lubricating fluid can be circulated from the main chamber to the auxiliary chambers and then back into the main chamber again,  thereby constantly lubricating the bearing assemblies with cool,  clean,  and effective lubricating  fluid.    Furthermore,  a  lubricating  fluid dispenser is mounted on the pump shaft within the main chamber,  the dispenser being positioned entirely above the  lubricating fluid level  such that heat  generation within  the  main  chamber  is  reduced,  the  dispenser dispersing the lubricant throughout the main chamber by way  of  an  air-flow  created by  vanes  defined  in  the dispenser.  This design also allows the lubricating fluid level within the main chamber to be maintained below the moveable portions (i.e. bearing balls and rotating frame portion)  of  the  shaft bearing assemblies  so  that  the bearings run at lower temperature thereby extending the working life of the bearing assemblies.

Patent CA-2154677-A1 (CA)
Title: Electrochemical controlled dispensing assembly and method
Inventor: HORRES CHARLES R JR
IPC: A61M5/142
Filed: 1994-02-01
Abstract: A pump assembly (20) employs electrochemistry to selectively control the delivery rate of a dispensing fluid (21) from a dispensing reservoir (24) by selectively controlling the flow rate of a driving fluid (19) from a driving reservoir (23) to a receiving reservoir (33). A partition (25), separating the driving reservoir from the receiving fluid reservoir, includes at least one aperture (28) which is opened or closed depending upon an electrical signal from a remote programing unit. Flow into the receiving reservoir deflects a barrier member to expel dispensing fluid from the dispensing reservoir. The dispensing fluid flow rate can be programmed to provide an appropriate steady or varying flow rate; user-initiated pulses of dispensing fluid can also be provided. A method of controlled infusion of an infusate employing electrochemistry is also provided.

Title: Method of producing image data, image data processing apparatus, and recording medium
Inventor: TANAKA MASAYOSHI
IPC: G06T15/00
Filed: 1995-11-28
Abstract: A method and apparatus includes a geometry transfer engine (GTE) 61 acting as a coordinate transforming means for converting three-dimensional image data of TMD format into  two-dimensional  image  data  by  perspective  view transformation, and a graphics processing unit (GPU) 62 acting  as  a  drawing means  for  transferring  the two-dimensional  image  data  in  a  given  transmission standard to draw an image on a two-dimensional display screen.  A structure of the three-dimensional image data, excluding  the  information  to  be  perspective  view transformed, is arranged identical to that of the given transmission standard of the two-dimensional image data. Accordingly,  in  the  GTE  61,  the  information  to  be perspective view transformed is discriminated from the other data of the three-dimensional image data wherein the  structure  is  identical  to  that  of  the  given transmission standard of the two-dimensional image data, subjected to the perspective view transformation, and is combined with the other data wherein the structure is identical to that of the given transmission standard for production  of  the  two-dimensional  image  data.    An original format file including data to be transformed is thereby easily converted into a file having a new format.

Inventor: WILSON JOSEPH G
IPC: B60Q1/44
Filed: 1996-02-01
Abstract: A vehicle deceleration warning light is disclosed that includes a pressure switch in fluid communication with the master hydraulic brake cylinder. When the pressure reaches a predetermined level that is representative of panic or emergency braking, the pressure switch activates a delayed and latched switch that, after a suitable interval, turns on a contrastingly colored flashing warning indicator on the rear deck of the motor vehicle to warn a following driver of the rapid deceleration. The flashing indicator continues its flashing for a predetermined amount of time, even after the pressure on the pedal has been released.

Patent CA-2169305-A1 (CA)
Title: Board drying process and device
Inventor: BAHNER FRIEDRICH
IPC: F26B15/12
Filed: 1994-07-27
Abstract: In order to dry boards, the boards are guided on racks through a drier and brought into contact with drying air in two stages. In a stage A with a higher drying power, the drying air is supplied at a higher temperature and with an at least average humidity, and in the other stage B, it is supplied at an average temperature and with a low humidity. The waste heat of the outgoing air from stage A is used for preheating the drying air. This process should reduce the consumption of primary energy. For that purpose, a process is known that consists in also using the outgoing air condensation heat. This has the inconvenient, however, of requiring substantially more secondary energy, as important air mass flows are required to transfer heat because of the low condensation temperature. Primary energy should be reduced by using condensation beat without substantially increasing secondary energy requirements.  According to the invention, the outgoing air from stage A is supplied to stage B through a heat exchanger arranged in the rack of the drier. The drying air of stage B is supplied in counter-current through the drier with a low humidity and temperature, so that the boards are dried in stage B both by condensation heat and by radiant heat. Thus only a reduced mass flow of drying air is required to transfer the condensation heat. The consumption of primary and secondary energy is low. This invention is suitable for drying boards, in particular boards for buildings, such as gypsum plaster boards and fibre boards.

Le changement de vitesse s'effectue par la déflexion axiale des secteurs élastiques (15', 15'') de façon que les rangées de dents des couronnes adjacentes (2, 3, 22, 23) soient réciproquement alignées, ce qui permet de transférer une chaîne à rouleaux (5) entraînée autour d'une couronne dentée (22, 23) vers une couronne (23, 22) adjacente d'un diamètre de cercle primitif différent, en vue de modifier le rapport de transmission. Un système de commande (8, 99, |00, 101) est mécaniquement accouplé à un mécanisme de déflexion de secteur élastique (30, 39, 40, 41). Ce système de commande (8, 99, 100, 101) détermine automatiquement laquelle des couronnes d'entraînement (3, 21, 22, 23) et laquelle des couronnes entraìnées (2, 21, 22, 23) est en prise avec la chaîne (5) et sélectionne soit l'empilage (3) de couronnes d'entraînement, soit l'empilage (2) de couronnes entraînées pour effectuer le changement de vitesse, permettant ainsi à un cycliste d'augmenter ou de réduire a volonté le rapport de transmission.
