Abstract: Apparatus for tightly wrapping a package such as disposed on a pallet in a thin film such as for shipping or storage includes a rotating deck adapted to receive the pallet and package to be wrapped. The deck is directly coupled to and supported by a gear box driven by an electric motor. The apparatus further includes a film wrap supply in the form of a roll which lets out the film for wrapping around the package as the deck and package rotate. A manually adjustable tensioner allows for adjusting the stretch of the wrapping film on the package, while the film wrap supply may be adjusted vertically to permit wrapping the package over its entire vertical dimension regardless of the width of the roll of film wrap. A foot control allows an operator of the apparatus to rotate the deck and the package being wrapped while vertically moving the film wrap supply roll to fully enclose the package within the wrapping film.

Title: Catadioptric one-to-one telecentric image combining system
Inventor: CHEN CHUNGTE W
IPC: G02B27/00
Filed: 1997-03-04
Granted: 2001-05-15
Abstract: A catadioptric one-to-one optical relay system which is telecentric in both object and image space. The system includes three modules, which include a spherical primary mirror, a spherical secondary mirror with a zero power doublet for axial color correction, and an X-prism for spectral division. The chromatic aberration generated by the X-prism is compensated by the zero power doublet corrector. Because the system is telecentric in both object and image space, the coatings associated with the X-prism are simplified. The system can be used in telescopes, optical systems with sensor protection, and color CCD assemblies.

Title: Efficient synthesis of musical tones having nonlinear excitations
Inventor: SMITH JULIUS O III
IPC: G10H5/00
Filed: 1996-05-10
Granted: 2006-12-05
Abstract: An efficient digital waveguide synthesizer is disclosed for simulating the tones produced by a non-linearly excited vibrational element coupled to a resonator, such as in a piano. In a preferred embodiment, the synthesizer creates an excitation pulse from a table containing the impulse response of a piano sound board and enclosure. Alternately, this excitation pulse can be synthesized by filtering white noise. The excitation pulse is fed into the filter that simulates the collision of the piano hammer and string. Because the hammer-string interaction is nonlinear, the characteristics of this filter vary with the amplitude of the tone produced. The filtered excitation pulse is then fed into a filtered delay line loop which models the vibration of a piano string. Because the excitation pulse already contains effects of the resonator, the tone produced by the delay line loop does not require additional filtering in order to model the resonator.

Granted: 2007-01-02
Abstract: An apparatus and method are disclosed that allow for downhole expansion of long strings of rounded tubulars, using a technique that expands the tubular from the top to the bottom. The apparatus supports the tubular to be expanded by a set of protruding dogs which can be retracted if an emergency release is required. A conically shaped wedge is driven into the top of the tubing to be expanded. After some initial expansion, a seal behind the wedge contacts the expanded portion of the tube. Further driving of the wedge into the tube ultimately brings in a series of back-up seals which enter the expanded tube and are disengaged from the driving mandrel at that point. Further applied pressure now makes use of a piston of enlarged cross-sectional area to continue the further expansion of the tubular. When the wedge has fully stroked through the tubular, it has by then expanded the tubular to an inside diameter larger than the protruding dogs which formerly supported it. At that point, the assembly can be removed from the wellbore. An emergency release, involving dropping a ball and shifting a sleeve, allows, through the use of applied pressure, the shifting of a sleeve which supports the dog which in turn supports the tubing to be expanded. Once the support sleeve for the dog has shifted, the dog can retract to allow removal of the tool, even if the tube to be expanded has not been fully expanded.

Title: Chew toys for domestic carnivorous animals and method for making same
Inventor: SHERRILL LES R
IPC: A01K11/00
Filed: 1997-09-25
Granted: 2004-03-09
Abstract: Chew toys (10) for domestic carnivorous animals having rawhide (11) and jerky sheets or members (12). The jerky sheets (12) are wrapped in a rawhide sheet (11) by either rolling or folding. This provides an outer layer (18) of rawhide containing jerky therein. A seam (19) is created in rawhide outer layer (18) by the rolling or folding of the rawhide sheet (11). The jerky (12) preferably extends through this seam (19) to provide an initial attractive odor and taste for the dog and provide an immediate starting point for chewing. The benefits of the jerky (12) and the rawhide are maximized throughout the entire chewing process of the chew toy (10). Dogs are highly attracted to the scent and taste of jerky (12), which causes the dog to chew on the rawhide (11) for extended periods of time. This better satisfies the dog's instinctive urge to chew, channeling it in a healthy direction, while simultaneously reducing the tartar on their teeth. The jerky (12) is positioned with respect to the rawhide (11) to enable the odor and taste sensations of the jerky (12) to always be present and fresh to the dog.

Title: Multiple drain method for recovering oil from tar sand
Inventor: SCHMIDT BRIAN H
IPC: E21B43/30
Filed: 1999-05-21
Granted: 2008-09-30
Abstract: A thermal method is described for recovering normally immobile hydrocarbon oil from a subsurface tar sand deposit. The procedure comprises: (a) establishing at least one substantially vertical production bore hole extending from the surface of the earth to at least the bottom of said subsurface formation; (b) providing a plurality of bore holes extending downwardly from the surface of the earth through the tar sand formation to substantially the bottom thereof and then substantially horizontally at or near the bottom of the tar sand formation and converging radially inward to each bore hole, each radial bore hole containing a perforated or slotted tube; (c) continuously injecting steam downwardly through the perforated or slotted tubes whereby the steam discharges through the perforations or slots and into the tar sand formation to reduce the viscosity of the normally immobile oil, with a substantial proportion of the steam being injected into the formation via the portion of each tube extending downwardly through the tar sand formation whereby the steam reduces the viscosity of the normally immobile oil over an area extending substantially between the perforated tube and the top of the tar sand formation with this viscosity reducing area expanding radially and moving axially inwardly toward the vertical production bore hole thereby creating an expanding generally conical-shaped production chamber; and (d) draining the less viscous oil and steam condensate thus obtained downwardly by gravity to the bottom of the production chamber and then through the horizontal tubes into the bottom of the vertical production bore hole for collection.
