Title: Production of high viscosity index lubricants
Inventor: MARLER DAVID O
IPC: B01J29/06
Filed: 1992-07-23
Abstract: Petroleum wax feeds are converted to high viscosity index lubricants by a two-step hydrocracking-hydroisomerization process in which the wax feed is initially subjected to hydrocracking under mild conditions with a conversion to non-lube range products of no more than about 40 weight percent of the feed. The hydrocracking is carried out using an amorphous or mesoporous crystalline catalyst which preferentially removes the aromatic components present in the initial feed. The hydrocracked effluent is then subjected to hydroisomerization in a second step using a low acidity hydroisomerization catalyst which contains a hydrogenation component, on a mesoporous support material. The mesoporous support material (for the first or second steps) comprises an inorganic, non-layered, porous, crystalline phase aluminosilicate material which exhibits a benzene adsorption capacity of greater than about 15 grams benzene per 100 grams at 6.7 kPa (50 torr) and 25 ·C and which, in its preferred catalytic form, has a uniform, hexagonal arrangement of pores with diameters of at least 1.3 µm (13 Å) and exhibiting, after calcination, an X-ray diffraction pattern with at least on d-spacing greater than 1.8 µm (18 Å) and a hexagonal electron diffraction pattern that can be indexed with a d100 value greater than 1.8 µm (18 Å) which corresponds to at least one peak in the X-ray diffraction pattern.

Abstract: A watering system for use in a greenhouse has a hose carrier that is supported entirely on a single track, the track having a rectangular cross-section.  The hose carrier is connected by a cable that winds through a series of pulleys to a drive system so that the carrier moves at one-half the speed of the drive system as the drive system moves along the track in either direction.  The water supply and electrical supply are connected at the approximate mid-point of the track and the hose carrier distributes the hose and electrical conductor among support brackets located along the track so that neither the hose nor the conductor become tangled. The tension on the hose and conductor is minimal as each support bracket has rollers thereon and the hose and/or conductor are not used to apply force to the hose carrier to move it along the track.  The support brackets on one half of the track can be much smaller than the support brackets on the other half of the track as the hose carrier travels on one-half of the track only.  Previous systems have used double tracks, which are more complex and more expensive.  Also, it is much more difficult to move a watering system from one track to another track when the track is double than it is when the track is single.

Title: Optical waveguide and method of fabricating the same
Inventor: HIROSE CHISAI
IPC: G02B6/136
Filed: 1994-01-13
Abstract: ABSTRACT OF THE DISCLOSURE    In the method for forming an optical waveguide according to this invention, an optical waveguide comprising a core of quartz as a main component, and a cladding layers surrounding the core is formed by deposition of glass fine particles by flame hydrolysis deposition and vitrifying the glass fine particle layers.          This method includes a step of transiently increasing a feed amount of phosphorus to a flame burner in forming glass fine particle layers to be the cladding layers.          Feeding phosphorus in this step for the first time after a glass fine particle layer is deposited without feeding phosphorus to the flame burner, whereby generation of foreign objects near the core can be suppressed.  The method for fabricating an optical waveguide according to this invention is for fabricating a core 132a or cladding layers 122 142 surrounding the core 132a by flame hydrolysis deposition and is characterized in that the glass fine particle layers are vitrified after the deposition of the phosphorus-content glass fine particle layer, whereby glass films 122a, 122b with a thickness of below 10 µm are formed.  This glass film forming step is repeated twice or more times to form the core or the glass layers to be the cladding layers surrounding the core.          This invention can suppress inhomogeneous vitrified films and especially can make phosphorus concentrations in the cladding layers uniform.  As a result, prapagation losses can be made small.

Title: Remote fiber optic electrical switch
Inventor: MULALLY DANIEL J
IPC: G02B6/42
Filed: 1992-12-24
Abstract: A remote switch (12) system for controlling electrical devices, such as electrical lights, from a remote switch (12) location using a single optical fiber to communicate the controlling signal from the remote switch (12) to the device. Typically, the remote switch (12) may be added to a normal switch (12) near the device during modification or remodeling of a building, automobile or the like or installed in during original construction. The fiber (24) optic system includes both an emitter and a detector (58) at the first end of a fiber optic (24). The emitter sends a light signal through the fiber (24) and the detector (58) detects a reflected signal coming back through the fiber. Conventional switching circuits or relays turn the electrical device, e.g. a light, to a different state, such as "on" or "off" in response to a pulse of light or the presence or absence of a returning signal. The remote switch (12) is located at the second end of the fiber and includes means for moving a retroreflector (52), preferably a sheet having a large number of very small, closely spaced, cube-corner or spherical lens retroreflectors (52) past or into and out of an operative position relative to the fiber end. Thus, the switch (12) can be used in a pulsed or a continuous reflection mode. Since the fiber is very small, it can be simply taped to wall surfaces and painted over, eliminating the need to feed wires through the wall. Additional remote switches may be added as needed simply and at little expense. Safety is enhanced, since no wires carrying electrical current extend to the remote switch (12).

Title: Acetylene converter moderators
Inventor: SLIM DAVID R
IPC: C10G45/34
Filed: 1993-05-12
Abstract: A process for removing acetylene from a hydrocarbon stream comprises exposing the stream to a hydrogenation catalyst in the presence of an acetylene converter modifier which substantially remains on the catalyst and does not unsubstantially migrate into the stream. Exposure is under conditions which are effective to support acetylene hydrogenation with enhanced selectivity. The moderator, which may be arsine or phosphine, is used at a low concentration level and serves to prevent temperature runaway during the exothermic acetylene hydrogenation reaction. By controlling the presence of moderator levels to such a relatively low level, temperature runaway during the highly exothermic acetylene hydrogenation reaction is prevented while maintaining acceptable catalyst activity levels for purposes of the acetylene hydrogenation reaction.
