Patent CA-2074196-A1 (CA)
Inventor: PIEPER JON R
IPC: B24D11/06
Filed: 1992-07-20
Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to endless coated abrasive articles, in particular, coated abrasive belts having a splice made by means of radiation curable adhesives.  The conventional method for making an endless coated abrasive article, i.e., a belt, involves the steps of cutting a coated abrasive sheet to the desired length, applying a splice adhesive over both cut ends of the side of the coated abrasive sheet not bearing abrasive, allowing the coated abrasive sheet to stand for a sufficient time to allow the solvent to flash off from the adhesive, abutting the two cut ends of the coated abrasive sheet to form a joint, applying a splice medium over the joint, and solidifying the splice adhesive.  The splice adhesive is typically solidified by heat and pressure.  The time required for the solvent to flash off can range anywhere from five to 60 minutes, thereby creating a bottleneck in the manufacturing process.  Furthermore, removal of the solvent gives rise to environmental concerns.   This invention provides a method of making the splice by using radiation curable adhesives, e.g., acrylated urethanes, and radiation energy to cure the adhesives. The radiation curable splice adhesive is essentially solvent-free.  Consequently, the time required for the solvent to flash off is eliminated and solvent removal is no longer an environmental concern.  By utilizing a source of radiation energy, the splice adhesive can be solidified in less than one minute.  Because the splice adhesive is fully solidified, coated abrasive belts can be packaged immediately after the splice is formed.   45568-7A.EPO

Title: Solutions of peracids
Inventor: BROUGHAM PAUL
IPC: C07C409/00
Filed: 1991-02-18
Abstract: A dilute solution of a lower aliphatic peracid such as peracetic acid, having an equilibrium composition, is produced by contacting hydrogen peroxide with a lower aliphatic acid each at initial high concentrations in an aqueous reaction mixture to rapidly form a reaction mixture containing, for example, up to 30% wt of peracid and diluting the reaction mixture with water and with any required quantities of lower aliphatic acid and/or hydrogen peroxide to reproduce the equilibrium composition of the dilute solution, the process being characterised in that the reaction mixture rich in lower aliphatic peracid is diluted before it has itself reached equilibrium, for example when it contains from 20 to 80% of its potential equilibrated content of peracid. The process provides a quick plant-efficient process for the production of stable dilute lower aliphatic peracid solutions for industrial disinfection purposes or for personal or domestic hygiene use.

Filed: 1992-11-10
Abstract: A media feed roll apparatus is provided for the transfer of articles such as envelopes, magazines and newspapers, one by one, from a stack to a transport which conveys these articles to a work station for printing or labeling.  The apparatus and methodology according to the invention allow for independent adjustment of the roller nip between upper drive rollers and lower facing rollers so that an article such as an envelope can be inserted into the nip with the roller pairs providing substantially equal nip pressure on the article.  Roller nip pressure is achieved through a mechanism allowing raising and lowering of the upper drive rollers, preferably by a pivotal action, which are independently suspended.  Upon being released from the mechanism, the rollers are biased toward the article thereby creating substantially equal nip pressure on the article even if the nip spacing is different as a result of the article having different thicknesses.

Abstract: A rigid three-dimensional preform is made by moving a plurality of webs of fibrous reinforcement material superposed and coplanar to a cutter, the webs being coated with an electromagnetic energy-curable binder and pressed together. Prior to cutting a blank in a two-dimensional development of the three-dimensional preform from the webs, the webs are tacked together at spaced local zones by locally curing the binder at those zones by locally applying the appropriate electromagnetic radiation (microwave, ultraviolet, electron) so that the webs travel as one to the cutter. After cutting of the blank, the blank is loaded into a mold to replicate the three-dimensional shape of the preform and the remainder of the binder is cured in the mold by the application of the appropriate electromagnetic radiation. An auxiliary member may be attached to the preform by applying an electromagnetic energy-curable binder to at least one location on the preform, moving the auxiliary member into a desired position and intimate contact with the binder-coated location and the binder cured at that location by the application of the appropriate electromagnetic radiation.

Title: Intelligent telecommunications network
Inventor: ISIDORO ALESSANDRO L
IPC: H04Q3/00
Filed: 1993-03-26
Abstract: INTELLIGENT TELECOMMUNICATIONS NETWORK          Abstract Telecommunications services are implemented on a public switched telephone network by one or more services network elements, which may be adjuncts or service control points. The services network elements send high level call configuration commands to one or more switching systems which connect calling parties to called parties. The high level call configuration commands direct the switching system to change from a n initial call configuration to a final target call configuration which fully effectuates a desired telecommunication service. The switching system contains a processor which converts the high level call configuration commands to low level primitive messages which directly manipulate call processing resources in a switching system. The design of services network elements and the nature of communications between those network elements and the telecommunications switching systems is simplified by the use of these high level call configuration commands. Also, new services are easily developed and detrimental interactions with existing switching system features is avoided.

Inventor: NATWICK VERNON R
IPC: F04B49/10
Filed: 1992-07-17
Abstract: A cam assembly and method for providing a substantially constant load to a motor that drives the cam assembly. A torque compensated cam assembly (142, 300) includes a plurality of tracks (140, 150, 152/310, 312, 314) that are profiled with a surface that varies radially as the cam rotates, thereby actuating cam followers, each of which rolls along a different track. A tangential force developed by the cam followers as they move over rapid radial changes in the surfaces of the tracks produces a total net torque that at times tends to aid the rotation of the cam and at times tends to impede its rotation. In the application of the torque compensated cam assembly disclosed, the cam is used in a volumetric pump (30) that accurately delivers a desired volume of fluid at a desired rate. To assist in maintaining the accuracy of these parameters, the torque compensated cam assembly presents a substantially constant load to a motor (146, 304) that drives the cam. In one embodiment, the cam assembly includes a torque compensation track (170/316) disposed at one end of the cam, and in another embodiment, the torque compensation track is disposed circumferentially around the cam. A torque compensation roller (172, 320) is biased against the torque compensation track by a flexure (174), providing a force that develops thre required compensating torque. The profile of the torque compensation track is defined so as to produce a torque that is substantially equal in magnitude, but opposite in the direction, that it tends to rotate the cam assembly, compared to the net torque developed by the cam followers.
