Patent CA-2320093-A1 (CA)
Inventor: NOSENCHUCK DANIEL M
IPC: A47L5/12
Filed: 1999-02-04
Abstract: A vacuum cleaner has a vacuum pump with a housing (102) including a lobed chamber (104) having an epitrochoidal planform. The chamber has outlet ports (116o) and inlet ports (116i) in each lobe of the chamber, and a central stator gear (110). A triangular rotor (140) with curved sides is disposed for eccentric rotation in the chamber such that an inlet port and an outlet port in each lobe of the chamber are always in direct fluid communication during a portion of rotor travel, which prevents excessive pressure build-up at the chamber inlet ports, and a central rotor gear meshed with the stator gear. A drive disc (164) fits within a circular opening (149) in the rotor (140) and is mounted eccentrically to a drive shaft (162) driven by a motor to impart rotational motion to the rotor to generate air flow from the inlet ports (116i) to the outlet ports (116o) of the chamber (104). A ducting system connects the inlet ports of the chamber to a debris-collecting compartment. The vacuum cleaner supplies adequate cleaning power at lower rotational speeds and at lower air flow velocities, thus providing significant noise reduction.

Patent CA-2325376-A1 (CA)
Title: Modular foam dispenser
Inventor: CORRIGAN JOHN JOSEPH III
IPC: B29B7/76
Filed: 1999-03-12
Abstract: A dispenser for mixing foam precursor chemicals and dispensing the foamable mixture includes a first module (28) containing shutoff valves (42, 44) and a second module (30) containing a dispensing valve assembly (54). The dispensing valve (54) assembly includes a valve body (82) of a self-lubricating material and a valuing rod (56) which is reciprocatingly retracted in a valve passage (84) of the valve body (82) to uncover orifices (86, 88) which supply the precursor fluids into the valve passage (84), from which the mixed chemicals are dispensed. The dispensing valve (54) assembly includes a die spring (94) which urges a washer (90) to compress the valve body (82) along its axis to help prevent cold flow of the valve body away from the valving rod (56). The valving rod is scraped by inner surfaces of the hole (92) in the washer (90) through which the valving rod (56) is retracted and extended. The die spring (94) is preloaded and retained by a load cylinder (96) which is fixed in the bore (52) in the second housing (50) which contains the dispensing valve (54). An end portion of the load cylinder (96) extends from the bore (52) and carries a thrust ring (180) which engages grooves (184) in the first and second housings (32, 50) for preventing relative movement between the two modules (28, 30) along the axis of the bore (52). A cap (72) secured within the dispensing end of the bore (52) forms an annular solvent receiving chamber (190) surrounding an end portion of the valving rod (56). The valving rod tip (186) is rounded and is exposed to the annular chamber (190) when the valving rod (56) is in a non-dispensing position, so that solvent flowing into the annular chamber (190) flows outwardly over the tip (186) to clean foam chemicals therefrom. The cap outer face (198) and rod tip (186) are coated with a release material such as TFE.

Title: Pipe connection gasket
Inventor: ZIMMERLY ROBERT D
IPC: F16L23/22
Filed: 1999-04-01
Abstract: A gasket (70) is provided for joining lengths of pipes (12, 14) having dissimilar end faces (28, 46) which are of approximately equal diameters and which are substantially normal to the longitudinal axis of the pipes (12, 14).  The end faces (28, 46) each include a circular recess (34, 49) which are of differing diameters. The gasket has a first side which has a surface contour which is a mirror image of one of the faces and the opposite side has a surface contour which is a mirror image of the other end face. The outer periphery (72) of gasket (70) is of a substantially lesser thickness than its inner marginal portion (74) so that compression during use of the thicker inner marginal portion is minimized.

Abstract: A fume hood control apparatus for controlling the flow of air through the fume hood in a manner whereby the effective size of the total opening to the fume hood, including the portion of the opening that is not covered by one or more sash doors will have a relatively constant average face velocity of air moving into the fume hood. The apparatus includes a simple and reliable sash door sensing means for sensing the position of the moveable sash door by using a rotary position sensor with a lever arm mechanism which translates horizontal or vertical movement to rotary movement for determining the position of the sash door. The apparatus compensates for nonlinearity that result from the translation.

Patent CA-2335811-A1 (CA)
Title: Method and apparatus for the production of purified plasma proteins
Inventor: SHANBROM EDWARD
IPC: C07K14/745
Filed: 1998-06-23
Abstract: Enhanced production of cryoprecipitate is produced by dehydrating an individual unit of plasma prior to a low temperature step used to produce cryoprecipitate. This dehydration is accomplished either by placing a water absorbing material within a blood bag so that plasma occupying the bag will become dehydrated or by placing the water absorbing material within a cartridge so that plasma becomes dehydrated upon flowing through the cartridge. The preferred water-absorbing material is a cross-linked chromatographic gel having pores too small to admit clotting proteins, but large enough to admit water molecules. Suitable gels are made from carbohydrates or polyacrylamide. Carbohydrate gels such as Sephadex®, produced by Pharmacia-Upjohn, are particularly preferred in the present invention. An alternative embodiment of the invention replaces the simple water-absorbing gel with one that also has ion exchange capabilities, such as DEAE (diethy-aminoethyl) Sephadex® which has a special affinity for a number of blood clotting factors collectively known as the prothrombin complex. Following the dehydration step the DEAF Sephadex® is eluted to produce prothrombin complex.

Title: Air-routing system, particularly intake system of an internal combusion engine
Inventor: SCHOLL HANS-PETER
IPC: F02M35/10

Abstract: The invention relates to an air-routing system, especially a suction system of an internal combustion engine. The inventive system makes optimal use of the  available installation space by integrating a bypass channel (25) into the suction module. The volume of the bypass channel also provides an acoustic shield for the collector chamber (22). The free screwing area (13) behind th e fastening flange (11) that is required for mounting the suction module (11) is used by an air intake hood (14) which can be placed on the filter housing (1 5) after the suction module has been mounted. This ensures that there is a greater volume available in the filter housing (15), hereby reducing the muzzle noise on the air intake part of the suction module.
