Title: Polyurethane films prepared by electrodeposition from polyurethane dispersions
Inventor: KOONCE WILLIAM A
IPC: B29K75/00
Filed: 2000-04-13
Abstract: A process for preparing polyurethane films is disclosed, comprising electrodepositing the film onto a substrate from a polyurethane dispersion.  One advantage of the electrodeposition process of the present invention is that there is no need for an additional step to remove coagulants from the films, as with conventional coagulation processes. Another advantage is that in using electrodeposition, the amount of water that must be removed during a dewatering step is minimized. A third advantage is that the resulting film demonstrates much greater uniformity in thickness as compared to films prepared by conventional coagulation techniques. The present invention has applicability in, for example, medical applications.

Title: Bag with reusable built-in closure tab
Inventor: SCHUETZ JEFFREY M
IPC: B65D30/02
Filed: 2002-02-15
Abstract: A bag having a built-in closure tab is defined. The closure tab is formed from the outer layer of the laminate which makes up the bag. When a user of the bag wishes to close the bag, the user folds or rolls the sides of the bag together down the side of the bag having the tab. The tab is partially separated from the rest of the outer layer of the laminate. A pressure sensitive adhesive disposed on the interior surface of the tab is used to affix the tab to the rolled down portion of the bag, preventing unwanted opening of the bag. The tab may be affixed and removed from the rolled down portion a number of times, thereby allowing the user to open and reseal the bag as many times as desired.

Title: Method and apparatus for bandwidth allocation
Inventor: STANWOOD KENNETH L
IPC: H04L12/56
Filed: 2000-05-19
Abstract: A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The inventive method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a "polling" method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a "poll-me bit" or, alternatively, it may be periodic. Another technique comprises "piggybacking" bandwidth requests on bandwidth already allocated to a CPE. In accordance with this technique, currently active CPEs request bandwidth using previously unused portions of uplink bandwidth that is already allocated to the CPE. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE. By using a combination of bandwidth allocation techniques, the present invention advantageously makes use of the efficiency benefits associated with each technique.

Patent CA-2380735-A1 (CA)
Inventor: SNELLING DAVID R
IPC: G01N21/71
Filed: 2002-04-05
Abstract: The laser-induced incandescence (LII) to analyze characteristics of submicron sized particles is described. LII is recognized as a good tool for determining the characteristics of small particles in a gas, e.g., volume fraction, particle size, and specific surface area. It uses the fact that transient cooling is dependent on the specific surface area of the particle, which is related to diameter of the particle. In LII, particles are heated by a pulsed laser light beam to a temperature where incandescence from the particles can be distinguished from ambient light. The surface temperature of particles and their volume fraction governs the incandescence. The temperature decay is proportional to the primary particle size. The invention uses an optical arrangement that ensures a near-uniform laser energy distribution spatial profile. The invention also uses a low fluence laser beam pulse to avoid evaporation of particles. Without significant evaporation and with a uniform energy profile, accurate and precise measurements can be conducted more easily and reliably.

Title: Anti-freezing and deicing composition and method
Inventor: BLOOMER TODD A
IPC: C09K3/18
Filed: 2002-06-25
Abstract: A composition is proposed for use in preventing the formation of ice or snow on outdoor surfaces, such as roadways or aggregate stockpiles, and also for deicing surfaces upon which snow or ice has formed. The composition is formed from a waste product of the process of removing sugar from molasses, also known as desugared molasses. As a byproduct of a widely used process for making edible sugar, the desugared molasses is readily available at a low cost.  Moreover, the composition is ready for use in conventional spraying equipment without the need for mixing agents, is environmentally friendly, and is able to perform at temperatures well below the freezing point of water. The composition is also non-corrosive and can be admixed with chloride salts, such as magnesium, calcium, or sodium chloride, to reduce the corrosiveness of the resulting solution while still providing effective deicing activity.

Abstract: A zeolite A or an A/X mixture having an LCC > 70 g liquid/100g zeolite (hydrated) and a cold water CER > 200 mg CaCO3/gram anhydrous zeolite (hydrated). The zeolite product may have a crystal size of 0.1-0.7 microns, a bulk density of 0.19-0.37 g/ml, and a median particle size of 1-5 microns. A process for making zeolite A or A/X  mixtures is also claimed, including mixing a sodium silicate solution, a sodium aluminate solution, and an amorphous aluminosilicate initiator gel in a mixing vessel to create an aluminosilicate synthesis gel, and crystallizing the aluminosilicate synthesis gel to form zeolite crystals. The sodium aluminate solution may be added gradually to at least the sodium silicate solution at a rate of about 1-5% of the total batch alumina per minute, and/or a percentage of the total batch alumina may be added as alumina trihydrate (ATH) powder. The amount of total batch alumina added as an undissolved source of soluble alumina and the presence or absence of initiator or "seed" gel determines whether the resulting zeolite product is an A/X mixture or only zeolite A. A process to augment the yield of a synthesis mixture is also claimed, comprising providing undissolved alumina in substantial excess of stoichiomeric requirements in a primary crystallization step, yielding a slurry of crystalline zeolite A in an alumina-enriched mother liquor, and then adding soluble silicate to initiate a second stage of very rapid crystallization.  Detergents containing zeolites of this invention are claimed.

Patent CA-2405165-A1 (CA)
Inventor: KIND LAWRENCE F
IPC: D06M101/04
Filed: 2001-03-29
Abstract: Specific transfer methods and articles to impart a metal-ion based antimicrobial finish to recipient textile surfaces. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. In particular, the inventive method involves the application of a solid, inorganic antimicrobial material to a donor substrate (such as a dryer sheet), and the subsequent placement of such a substrate within a tumble drying machine containing textile fabrics and operating the machine. The donor substrate, upon contact with the recipient textile fabrics, transfers antimicrobially effective amounts of the metal-ion based compounds to such recipient fabrics thereby imparting at least a temporary antimicrobial finish over at least a portion of such fabrics. The donor substrates, with either the antimicrobial compound alone or mixed with standard tumble dryer additives (such as perfumes, fabric softeners, fiber lubricants, and the like) are also contemplated within this invention.
