Abstract: The present invention a siding panel made from injection molded materials and having positioning relief to facilitate installation. The siding panel includes a plurality of decorative elements with formed with a top edge disposed above a row of decorative elements. Apertures are formed in the panel below the top edge and on the rear side of the siding panel. The panel includes a plurality of tabs, each narrower than the apertures to provide the positioning relief, which depend downward from the rear side, with the tabs being spaced in intervals corresponding to the apertures. The decorative elements are arranged in upper and lower rows which are offset to define relatively discontinuous side edges. The panel is formed from polypropylene, and the decorative elements comprise a simulated wood grain finish to be used as cedar shake shingles. The tab is about one half the width of each aperture, with the apertures being disposed through the siding panel at an angle extending downward. The panel also includes a second pair of tabs disposed on the rear of each of said upper and lower rows of decorative elements on the side edge to define a pair of discontinuous grooves. A pair of tongues extends from the other side edge, with the grooves structured and arranged for receiving tongues of a horizontally adjacent panel, with the tongues being longer than the second pair of tabs and the tongues and tabs having complimentary interlocking channels. The method of installing a wall covering formed of plurality of horizontal courses of siding panels involves installing first and second panels such that said first panel and said second panel are disposed relatively diagonally so said first panel is lower and laterally offset from said second panel. The third panel is installed by either: (A) inserting the tabs on the rear of the third panel into apertures of the lower panel and shifting the third panel horizontally to engage grooves of the third panel with tongues of a second laterally adjacent panel;  or (B) initiating engagement of grooves of the third panel with tongues of a second laterally adjacent panel and concurrently inserting tabs on the rear of the third panel into apertures of the lower panel, while concurrently completing engagement of grooves of the third panel with tongues of the laterally adjacent panel.

Abstract: The invention provides clay-free, preferably biopolymer free, well drilling and servicing fluids comprising an aqueous divalent cation-containing water soluble salt, a bridging agent, and a pre-gelatinized crosslinked amylopectin starch suspending agent and fluid loss control additive. The concentration of the starch derivative is sufficient to provide the fluid with the following charactersitics: (a) a low shear rate viscosity less than about 10,000 centipoise; (b) a high shear rate viscosity at 511 sec-1 in the range from about 15 to about 70 centipoise measured at 120°F; (c) a fluid loss less than about 10 milliliters as measured at 185°F and 250 psi differential pressure across a 5 micron disk for 30 minutes; and (d) anti- settling characteristics as exhibited upon static aging the fluid for 16 hours at 185°F. The low shear rate viscosity of the fluids can be increased without increasing the high shear rate viscosity above about 70 centipoise by incorporating magnesium oxide and/or dipotassium hydrogen phosphate in the fluids. The invention also provides a method of making the clay-free well drilling and servicing fluid and a process of drilling, completing, and working over a well with the clay-free fluid.

Abstract: A motor base for use in vibratory apparatus. The vibratory apparatus includes at least one eccentric drive having a driven shaft rotatably mounted on a moveable exciter. A motor is provided having a motor shaft which is spaced from the eccentric drive and coupled to the eccentric drive by a drive belt. Rotation of the motor is transferred by the drive belt to the eccentric drive, which generates a vibrational force. The vibrational force moves the exciter in various directions during operation of the vibratory apparatus. The motor base comprises a rigid support, such as an arm, having a free end adapted to carry the motor. The arm is supported to move about an axis of the driven shaft, so that the arm maintains a center distance between the motor shaft and the driven shaft. A resilient support, such as a compression spring, is attached to the free end of the arm, below the motor, to absorb any resulting forces acting on the arm from the movement of the exciter. The motor base maintains a center distance between the motor shaft and the driven shaft, thereby increasing drive belt life by minimizing tension variations in the drive belt.

Granted: 2007-07-24
Abstract: The invention pertains to a process for preparing spherical oxide particles comprising the steps of shaping a starting material comprising an oxide hydrate into particles of substantially constant length by leading the material to a set of two rolls rotating towards each other followed by leading the material to a roll equipped with grooves to form rod - type shapes, cutting the rod-type shapes into particles of substantially constant length, converting the thus formed particles into spheres, and heating the particles to convert the oxide hydrate into an oxide. The process results in particles in which there is substantially no difference in density between the core portion and the shell portion of the particles, which results in a high abrasion resistance. The particles prepared by the claimed process are particularly suitable for the preparation of hydroprocessing catalysts, more in particular for the preparation of hydroprocessing catalysts suitable for the hydroprocessing of heavy hydrocarbon feeds.

Granted: 2009-07-21
Abstract: The invention relates to a method and a device for reducing the speckle that is formed on a projection display when a coherent light source (1) is used.  Before being projected, the light coming from the light source strikes an electrically controllable optical element (4) with a spatially inhomogeneous index of refraction and penetrates said optical element, whereby the index of refraction within the period of projection is temporally altered. This leads to the averaging out of the speckle pattern on the projection screen (6). A multimode light source is preferably used for illumination and/or the light coming from the light source is split into several spatial modes in order to increase the effect. The light from the light source is preferably split by being coupled into a multimode light-conducting fibre. Said optical element is advantageously a liquid crystal element consisting of at least two liquid crystal layers, to which a position-dependent voltage is applied in order to produce a position-dependent index of refraction and whose birefringence is compensated by the appropriate alignment of the layers in relation to each other.
