Abstract: A fluid powered rotary actuator having a body with first and second ends. The body has a generally cylindrical interior sidewall with a grooved, inwardly facing circumferential portion. The body is adapted for coupling to a first external member. A drive member extends generally coaxially within the body and is supported for rotation relative thereto. The drive member has an end flange positioned toward the body first end adapted for coupling to a second external member, and a shaft rigidly attached to the end flange. The shaft has a grooved, outwardly facing circumferential sidewall portion positioned within the body toward the body second end and a smooth, outwardly facing circumferential sidewall portion positioned within the body between the end flange and the shaft groove sidewall portion. The end flange extends laterally outward beyond the shaft smooth sidewall portion and the shaft grooved sidewall portion has an outer diameter equal to or less than the outer diameter of the shaft smooth sidewall portion. The shaft grooved sidewall portion is formed as an integral part of the shaft, and the end flange as an integral unit with the shaft. The actuator further includes an annular piston sleeve positioned within the body and having a central aperture receiving the shaft therethrough. The piston sleeve is mounted for reciprocal axial movement within the body in response to selective application of pressurized fluid to a piston portion thereof in sliding sealed engagement with the shaft and body smooth sidewall portions to define fluid compartments to each side thereof. The sleeve portion has a grooved, inwardly facing circumferential sidewall portion engaging the shaft grooved sidewall portion, and a grooved, outwardly facing circumferential sidewall portion engaging the body grooved sidewall portion as the piston sleeve reciprocally moves within the body to translate axial movement of the piston sleeve into rotation of the drive member.

Title: Volumetric pump with bi-directional sphincter seal
Inventor: JACOBSEN STEPHEN C
IPC: H01F7/02
Filed: 1998-01-22
Granted: 2008-07-22
Abstract: A volumetric pump comprises a housing having an elongate cavity with open and closed ends. A resilient sheet of material having two branched portions forming an aperture is disposed over the housing. A pump shaft is slidably disposed through the aperture such that one branched portion toward the cavity and the other branched portion extends away from the housing such that a sphincter seal is formed about the shaft. An inlet conduit leading from a fluid source passes through the housing into the cavity near one end thereof, and an outlet conduit leading to a fluid sink passes through the housing from the cavity near the other end thereof. The shaft is driven back and forth in reciprocating motion, to alternatively produce a positive pressure forcing fluid out of the outlet conduit to the fluid sink, and a negative pressure forcing fluid from the fluid source through the inlet conduit.
Patent CA-2228586-C (CA)
Inventor: HOYER FRIEDRICH
IPC: B01J2/24
Filed: 1998-02-04
Granted: 2001-01-23
Abstract: In the method, calcium chloride scales (75) are produced on a cooled surface (20), namely through the application of a layer (70) consisting of an aqueous CaCl2 solution (7) to the cooled surface, solidification of the layer and stripping off the solidified layer. The solution contains less than 70 % CaCl2 by weight, preferably less than 65 % CaCl2 by weight. The layer thickness is set to a maximum of about 1 mm. A relative speed between the point of application of the solution and the cooling surface is produced so that a specific production rate of at least 20 g/s m2 is connected with this relative speed. The heat is carried off so rapidly through the cooling surface that the solidified layer remains largely free from calcium chloride dihydrate, CaCl2~2H2O. Dry scales thus arise.
