Title: Alkenyl succinic anhydride size emulsification with a natural gum for paper products
Inventor: NOWICKI ROMAN J
IPC: C09K23/56
Filed: 1999-04-06
Abstract: A natural gum is used to provide improved emulsification of alkenyl succinic anhydride (ASA) sizing agents for paper products.  The natural gum can be nonionic, cationic, anionic, amphoteric, oxidized, derivatized, or modified. The preferred natural gum is from the family of galactomannan gums in which guar gum is a primary example. The alkenyl succinic anhydride (ASA) size emulsion formed with the natural gum improves stability and the film formed is evenly distributed, thereby promoting more uniform sizing of the paper product.  The ratio of the ASA to natural gum in the emulsion ranges from 0.01:1 to 100:1, and preferably 0.1:1 to 20:1. The amount of ASA size is 1 lb./ton to 10 lbs./ton of finished paper product and preferably 2 lbs./ton to 8 lbs./ton. A surfactant may be used to further improve the stability of the emulsion.

Title: Binder with elastic gusset
Inventor: MOOR MARC L
IPC: B42F7/14
Filed: 1999-04-05
Abstract: The invention provides a binder or portfolio (10) for carrying looseleaf paper, books, school supplies, etc. wherein said binder includes an expandable gusset (18) attached to the front (12) and back covers (14) of the binder. The covers (12, 14) of the binder are foldably attached to a central spine (16) and the gusset is split into two sections running along the periphery of the inner sides of the covers. The gusset is provided with a means for releasable attachment (24) such that when the front cover of the binder is folded over the back cover of the binder, the two sections of the gusset may be attached to one another, thereby securing the contents of the binder inside.  Preferably, the gusset is made from an elastic material such as neoprene and the releasable means of attachment is a zipper-type closure. This construction of the gusset from an expandable material allows oversized objects such as larger textbooks to be placed in the binder without damaging the structural integrity of the gusset and the binder when the binder is fastened shut. An embodiment is disclosed wherein the covers are provided with a window also substantially formed from an elastic material, further increasing the expandability of the binder. Means for securing such a gusset to a binder are also provided, specifically a means for biasing the gusset outward of the binder so that the gusset does not interfere with the insertion of items into the binder. This outward biasing of the gusset also facilitates the securing of the two portions of the gusset by the releasable closure means.

Title: A hydro-mechanical transmission planetary carrier support system
Inventor: PUETZ CRAIG ALLEN
IPC: F16H47/04
Filed: 2001-04-17
Abstract: In a hydro-mechanical transmission having a hydrostatic unit and a mechanical gear train, the hydrostatic unit is resiliently mounted in the transmission housing to reduce the transmission of noise and vibration to the housing. Movement of the hydrostatic unit is facilitated by mounting the planetary carrier on a ball bearing instead of taper roller bearings. The ball bearing allows the carrier limited movement transverse to the axis of rotation of the carrier. To further reduce wear of the gear faces, one or more of the meshing gears at the point of relative movement have crowned gear faces rather than straight gear faces. This avoids a single line of contact of the meshing teeth at the tooth edge.

Title: Slurries of abrasive inorganic oxide particles and method for adjusting the abrasiveness of the particles
Inventor: PRYOR JAMES NEIL
IPC: C09D163/00
Filed: 1999-10-21
Abstract: Autoclaving slurries of porous, inorganic oxide particles results in an increased abrasiveness of the particles as reflected in increased removal rates of a polished substrate at standard polishing conditions in chemical mechanical polishing operations. Slurries having novel abrasion properties, especially for silica-based slurries, are created. The increase in particle abrasivity strongly correlates with a decrease in particle surface area as determined by N2 adsorption (BET method). As a result, methods for obtaining  a desired abrasivity for a slurry can be practiced by heating a slurry of inorganic oxide particles to a BET surface area previously identified as associated with the abrasivity desired. The resulting slurries can be used i n conventional polishing machinery. The method is particularly suitable for preparing silica-based abrasive slurries.

Title: Electrostrictive fiber modulators
Inventor: KINO GORDON S
IPC: G02F1/01
Filed: 1999-10-28
Abstract: An apparatus modulates the phase of an optical signal. The apparatus includes an optical medium (110) for propagating the optical signal. At least one electrode (130, 132) is positioned in proximity with the medium (110). The electrode induces an electric field within the medium in re-sponse to an AC voltage to produce varia-tions in the index of refraction of the optical medium (110) through the electrostrictive effect. Preferably, the phase of the optical signal is modulated such that polarization components of the optical signal parallel to and orthogonal to the electric field experience an equal phase shift. In certain embodiments, a DC voltage is supplied to the optical medium. Alternatively, the DC voltage within the optical medium may arise from poling the optical medium. Certain embodiments of the present invention include two electrodes positioned on opposite sides of the optical medium. The apparatus is used in an interferometer to form modulation device or switching device.

Filed: 1999-11-09
Abstract: Cranberries are utilized at certain phases of development, prior to full red  color development, which are typically characterized by an acid profile conducive to producing flavorful, high-value products, such as juices. At select phases of development, the berries have a quinic acid content (216, 220) which is similar to fully red berries, but contain a citric acid conten t which is much higher than fully red berries. As a result, the juice from the se berries can be used with less need to add citric acid or citric acid juice, like lemon juice to modify flavor. The berries at the select phase of development typically have a light color, from pink to white, which can be quantified based on the anthocyanin level in the fruit or the resulting juic e.
