Patent CA-2516507-C (CA)
Title: Sleeve piston fluid motor
Inventor: HARTWICK PATRICK W
IPC: E21B4/02
Filed: 2004-02-19
Granted: 2011-08-23
Abstract: The present invention is a cylindrical linear fluid motor (10) comprising a plurality of reciprocating rotary piston sleeve (42) intermediate an inner coaxial hollow drive shaft (20) and an outer cylindrical housing (30).  Rotating disc valves (71) at both ends of the sleeve piston (42) control the sequential flow of high-pressure and low-pressure fluid through ports in both the drive shaft (20) and housing (30). High-pressure fluid acts on one end of the sleeve piston causing the piston to travel laterally along the drive shaft, with an inner set of roller balls (25) in linear raceways (24,46) ensuring no rotation between each piston and the drive shaft. The linear motion simultaneously affects exhausting of low-pressure fluid at the other end of the piston. Outer balls (50) are seated in the housing and a sinusoidal circumferential raceway (48) of each piston, to affect rotation in the piston from the lateral motion. As a piston reaches the limit of its linear travel the rotating disc valve (71) on one end closes inlet ports (15) and opens exhaust ports (17), while another rotating disc valve closes exhaust ports (17) and opens inlet ports (15) at the other end, causing the high-pressure fluid to reverse the piston's lateral direction of movement. The multiple pistons of a motor are rotationally sequenced to create consistent power production throughout 360-degree rotation, of the pistons.

Abstract: An apparatus for forming waste containing packs from a length of flexible tubing is formed of a housing having a top portion, an intermediate portion and a lower portion. The top portion displays an opening to receive waste material therein and a cassette containing a package of a flexible pleated tubing. The intermediate portion has a retractable guillotine-type member sealingly contacting the tubing dispensed from the cassette and extending downwardly into the lower portion of the housing. Retraction of the member causes waste material received in the tubing of the upper and intermediate portions of the housing to be dispensed in a closed end tubing in the lower portion of the housing.

Filed: 2004-08-27
Granted: 2009-11-24
Abstract: A method and apparatus for a beverage dispensing nozzle equipped with at least one flow director dispenses at lower flowrates. In a first embodiment, a single flavor beverage dispensing nozzle equipped with at least one flow director segments the flow and reduces the cross sectional area of the fluid stream, thereby forcing product to move downward. A second embodiment provides an improvement to an existing beverage dispensing nozzle, by adding at least one flow director in an annular channel of the beverage dispensing nozzle. The addition of the at least one flow director in the annular channel provides the beverage dispensing nozzle with the ability to dispense product at lower flowrates by increasing the velocity component of the exiting product. The exiting product now has sufficient energy to separate from the beverage dispensing nozzle. Methods for using the beverage dispensing nozzles with the at least one flow director are also presented.

Abstract: L'invention concerne un moule pour la coulée horizontale de métal liquide comprenant un corps de moule formant une cavité de lingotière à extrémités ouvertes présentant une extrémité d'entrée et une extrémité de sortie. Un élément à paroi perméable, annulaire, est monté dans le corps de moule de manière adjacente à l'extrémité d'entrée de la cavité de moule, une face intérieure dudit élément formant une face intérieure du moule. Une plaque de transition réfractaire est montée au niveau de l'extrémité d'entrée de la cavité de moule, ladite plaque de transition possédant une ouverture d'entrée de moule présentant une section transversale inférieure à celle de la cavité de moule, formant ainsi un épaulement annulaire au niveau de l'extrémité d'entrée de la cavité. Des moyens permettent l'alimentation en aluminium liquide dans l'ouverture d'entrée. Des conduits séparés permettent également l'alimentation en gaz dans l'épaulement et via des moyens à parois perméables afin d'obtenir une couche de gaz entre le métal et la face intérieure du moule. Un gaz qui est plus réactif avec de l'aluminium liquide est alimenté dans l'épaulement et un gaz moins réactif est alimenté via la paroi perméable. Les réactions avec l'aluminium liquide créent une peau ou coquille sur l'aluminium, ce qui assure un passage régulier dans le moule et permet un refroidissement secondaire plus rapide du lingot émergeant.
