Title: Variable displacement radial piston pump
Inventor: HANSEN LOWELL DEAN
IPC: F04C14/22
Filed: 2005-12-16
Abstract: A radial pump (10) has a housing (12) with a cylinder ring (30) is pivotally mounted therein. The cylinder ring has a circular aperture within which a cam surface (42) is formed. A cylinder block (44) rotates within the cylinder ring aperture and has a plurality of radially extending cylinders (46) each having port which selectively communicates with a fluid inlet and a fluid outlet as the cylinder block (44) rotates. A plurality of pistons (48) is slideably received within the plurality of cylinders (46) and engages the cam surface (42). An actuator (33) operably coupled to produce movement of the cylinder ring (30), which alters the spatial relationship between the cylinder ring and the cylinder block (44) to vary the amount that the pistons (48) move within the cylinders (46). The amount of movement of the pistons within the cylinders is directly related to the magnitude of fluid flow delivered by the pump (10) and moving the cylinder ring (30) thereby controls the fluid flow. Rotation of the bearing ring (40) produces less torsional drag (parasitic horsepower loss) than the sliding motion of the pistons (48) on a stationary ring, which allows for increasing speed of operation and less performance losses.

Filed: 2004-04-09
Abstract: Human and mammalian skin undergoes a variety of changes associated with chronological aging. Various environmental factors, disease states and genetic disorders may accelerate both the appearance of aging skin and also the structural and functional changes associated with aging skin. Ultraviolet radiation from the sun is one of the classic known and well-defined means of accelerating or worsening the aging of the skin and this is frequently termed photoaging. Other environmental factors, such as oxidative stress, free radicals, environmental toxins such as ozone and cultural customs or habits such as tobacco smoking are other known probe accelerators in photo aging skin. A wide variety of other factors known and unknown contribute to accelerated or premature aging of the skin. This invention discusses methods where electromagnetic radiation, in particular, light, can be used to photobiomodulate the activity of living cells to delay, diminish, retard or even reverse the structural and functional effects of aging of the skin and other living cells and tissues. In particular methods described for improving the appearance, structure, function of aging skin, including up and down regulating the genotypic markers for the phenotype of aging skin.

Patent CA-2540933-A1 (CA)
Inventor: TAYLOR ROY G
IPC: G06F17/22
Filed: 2006-03-21
Abstract: A word processing method designed to improve computer word searching, word storage capacity and the speed of text message communication. Application of the method utilizes two types of word encoding methods. One method uses a set of twenty-five words with each word encoded by one alphabet letter as a code identifier for specific code words listed in descending order from the most frequently used word in the language to those of lesser frequency. The second coding method uses the twenty-six alphabet letters and four special character symbols as phonetic codes defining forty one speech phonemes to code all words in the language. Both methods require fewer characters than that used in the normal English script format and can be used together or separately as a form of short hand writing for computer text and email applications to gain operational efficiencies in data input, data storage, and data transmission.
