摘要： Waxy distillates, or raffinates containing from as little as 10% wax but more typically about 30% wax or more are upgraded by a process comprising the steps of hydrotreating the waxy oil under conditions which convert less than 20% of the feed into products boiling lower than the feed to reduce the sulfur and nitrogen content of the oil followed by hydroisomerizing the hydrotreated waxy oil to reduce the wax content and increase the viscosity index. This oil having a waxy content of less than 30%, preferably less than 25%, can now be more easily dewaxed using conventional solvent dewaxing procedures. The advantage of the present process resides in the increased yield and/or stability of oil as compared to other upgrading, dewaxing processes which convert wax to light products. The isomerization catalyst is preferably a low fluorine content catalyst, more preferably a noble metal on 0.1 to less than 2 wt % fluorine on alumina catalyst, most preferably a noble Group VIII metal (e.g. Pt or Pd) on low fluorine content (less than 2 wt % fluorine) on small particle size alumina (less than 1/16 inch diameter) catalyst. The most preferred alumina support is a 1/20 inch trilobe.

摘要： A valve seat (28) having a generally saddle-shaped, eccentric surface (52); a groove (50) of constant depth and width formed in the eccentric surface, having sidewalls (70) perpendicular to the eccentric surface and a base (72) parallel to the eccentric surface; and a flexible O-ring (54) retained by friction within the groove. The groove sidewalls and base have a surface finish in the range of about 32 to 125, which provides sufficient smoothness to retain the O-ring in the required non-planar shape.The valve seat groove (50) can be produced according to the disclosed method, which is preferably implemented in a numerically controlled four-axis horizontal milling tool system. The valve seat part (100) is mounted in a fixture (102) on a rotary table (104) such that the part axis (56) is aligned with the longitudinal axis (Z) of the tool (106). Once the initial penetration position and depth of the tool (106) is established on the eccentric surface (52a) of the part (100), the only required machine movements are table rotation (104) and tool vertical axis movement (Y).

摘要： A method of preventing permeability damage due to clay swelling, disintegration and migration in subterranean formations producing oil and gas, where such formations are to be the subject of enhanced oil recovery techniques using anionic or caustic flood chemicals. Prior to the use of such enhanced oil recovery techniques, a cationic organic polymer capable of stabilizing clays is introduced into an oil reservoir treatment area followed by introduction of a sufficient amount of a non-anionic aqueous spacer fluid to cause the cationic organic polymer to reorient itself on the reservoir clays in a substantially monomolecular layer and manner such that it will continue to stabilize the reservoir clays but will not substantially react with the anionic or caustic flood chemicals to form permeability damaging precipitates or to decompose thereby reducing its clay stabilization effectiveness.

摘要： A one way draw curtain rod assembly providing either a left or right hand draw cord location. A pulley assembly on the curtain rod is invertible into either of two positions to enable the relocation of the draw cords with respect to the curtain on the rod. Triangularly disposed pulleys serve to rotatably support the draw cords with the pulley-cord relationship being changed upon curtain rod inversion so as to function in a like manner in either position. The pulley assembly is affixed to the larger telescopic rod member to partake of the added strength of said member. A master carrier includes a detachable component removable upon curtain rod inversion and reattachable to locate a curtain bar to receive the outer segment of the curtain.

摘要： A pulse multiplier includes a polarizing beam splitter, a wave plate, and a set of mirrors. The polarizing beam splitter receives an input laser pulse. The wave plate receives light from the polarized beam splitter and generates a first set of pulses and a second set of pulses. The first set of pulses has a different polarization than the second set of pulses. The polarizing beam splitter, the wave plate, and the set of mirrors create a ring cavity. The polarizing beam splitter transmits the first set of pulses as an output of the pulse multiplier and reflects the second set of pulses into the ring cavity. This pulse multiplier can inexpensively reduce the peak power per pulse while increasing the number of pulses per second with minimal total power loss.

摘要： A personal digital key (e.g., which can be carried by a human) contains a memory having different service blocks. Each service block is accessible by a corresponding service block access key. As the personal digital key (PDK) moves around, it is detected by sensors. The sensors report position data, thus enabling location tracking of the PDK. The sensors also provide a data path to various applications. An application that has access to a service block access key can therefore access the corresponding service block on the PDK. The sensors themselves may also contain service block access keys.
