Title: Belts for compliant calendering
Inventor: DAVENPORT FRANCIS L
IPC: D21F7/08
Filed: 1997-08-08
Abstract: A calender belt for the compliant calendering of a paper web includes an endless base substrate, a staple fiber batt attached to at least the outside of the endless base substrate, and a polymeric resin material totally impregnating the fiber/base composite structure comprising the endless base substrate and the staple fiber batt to a substantially uniform depth. That depth may be such that the polymeric resin material does not reach the base substrate, or partly or completely impregnates the base substrate.      A layer of polymeric resin material is built up upon the staple fiber material to a predetermined thickness. Once the polymeric resin material is cured, it is ground to a desired smoothness without exposing any fiber on the ground surface. That the penetration of the polymeric resin material into the staple fiber batt, and possibly into the base substrate, is to a uniform depth enables the calender belt to provide a uniform pressure pulse as it passes with a paper web through the nip in a compliant calender.

Title: Process for preparing a storage-stable mixture of polyisocyanate and phosphate
Inventor: FERENCE DONALD M
IPC: C08G18/38
Filed: 1996-03-26
Abstract: A process for preparing a liquid, storage-stable composition containing an organic polyisocyanate and an acid phosphate is disclosed. The process includes the steps of (1) heating a mixture of a polyisocyanate and an acid phosphate at a temperature in the range of from 60 ~C to 190 ~C for a time such that no phase separation occurs upon cooling the reaction mixture to ambient temperature, the mixture containing dissolved gases; and (2) subjecting the mixture to a negative pressure sufficient to remove at least a portion of the dissolved gases therefrom. The negative pressurization significantly slows the rate of carbon dioxide evolution thereafter and therefore enables much longer term storage-stability than is obtainable when the negative pressurization step is not performed, beacause it reduces problems associated with pressurization of containers.
Patent CA-2218689-A1 (CA)
Title: Binding assembly
Inventor: MILLER-BRUNS MARY KAY
IPC: B42F11/00
Filed: 1996-04-04
Abstract: A binding assembly including (1) a plurality of support strips; (2) layers of pressure sensitive adhesive (which could be repositionable, removable or permanent pressure sensitive adhesive) along front surfaces of the support strips; and (3) layers of release material on a rear surface of the support strips. The support strips are adhered together to form a support strip stack with inner edges of the support strips in alignment, with the layers of pressure sensitive adhesive on the support strips adhered to the layers of release material on adjacent support strips, and with the front surfaces of the support strips uppermost in the support strip stack. The binding assembly further includes binding means along the inner edges of the support strips that affords separation of the support strips and revolving of the support strips relative to each other around axes generally parallel to their inner edges. Only tension applied through a paper sheet adhered along the full length of the layer of pressure sensitive adhesive on the uppermost one of the support strips adhered in the support strip stack can be used to separate that one support strip from an adjacent support strip adhered to the layer of release material on the front surface of that one support strip and cause revolving of that one support strip away from the support strip from which that one support strip was separated.

Abstract: The invention is a small radio modified with mounting screws and a "momentary on switch" connected to the battery wires of the radio. When attached to the outside of the bathroom door frame it is activated when the door is closed.      My wife complained about the noise made by occupants of the bathroom. She suggested turning the water on or taking a radio in with you and turning it on. This had two drawbacks: 1. The added noise was in the bathroom which did little to muffle the noise outside. 2. Even if you had a radio you would forget to bring it in or turn it on.      The modified radio is mounted on the outside of the bathroom door frame. By closing the door the switch is activated to turn the radio on. As the switch automatically activated you do not have to turn the radio on. As the music is outside the bathroom it is heard by those outside which muffles the bathroom noise.

IPC: A23L3/10
Filed: 1996-10-15
Abstract: A thin walled, easily crushable container (11) with an integral or seamed-on bottom is filled with an edible material (10) which requires sterilization. The empty container has one end attached or integral that may have a concave slope relative to the inside of the container. A liquified or solidified inert gas is then inserted into the container. The container is then sealed with a concave shaped end (13) before the inert liquified or solidified gas has completely vaporized. The ends do not bulge under the pressure left after sterilization, which pressure is due to the pressurization effect of the inert gas and which pressure is enough to overcome the vacuum caused by the cooling of hot water vapor or steam above the edible material and gives the can the required rigidity.
