Abstract: A device to monitor tension in a fastener assembly such as a stationary bolt and a moveable nut for securing elements therebetween. The device is in the form of a washer for use in the assembly between the nut and the elements or the bolt head and the elements. In one example, a slot is provided in the surface of the washer and extends radially outwardly from the inner periphery thereof. A recess is formed in the bottom of the slot, creating at least one fulcrum point in the slot. A monitor and indicating strip, for example a spring steel, is located in the slot and, under tension from one of the fastener assembly members, the distal end of the strip rises from the slot to provide a visual and measurable monitor of tension in the assembly. In another example, the monitor strip is located on the surface of the washer and the fulcrum is located on one of the fastener elements, such as on the underside of the nut, for engaging the strip under pressure, causing its distal end to rise.
Abstract: A novel method has been discovered for the pretreatment of cellulose with acetic acid and acetic anhydride under pressure, resulting in uniformly activated cellulose fibers. The improved process for producing cellulose diacetate comprises the steps of: (1) pretreating and activating the fluffed cellulose fibers in a solution of glacial acetic acid and acetic anhydride at room temperature and elevated pressure for a specific time; (2) mixing the activated cellulose containing acetic acid and anhydride further with a mixture of glacial acetic acid, acetic anhydride and sulphuric acid catalyst and acetylating the cellulose at specific initial and end temperatures to form primary cellulose acetate; and (3) partially neutralizing the sulphuric acid catalyst and destroying the excess acetic anhydride by adding an aqueous solution of magnesium acetate with dilute acetic acid to provide an excess of water in the reaction dope for hydrolysis at elevated temperature and pressure conditions.
Abstract: A method is described for improving the removal of toxic resin acids and fatty acids from pulp and paper effluent and from other streams containing resins and fatty acids. The addition of an anionic material, such as albumin, gelatin, alginate or alginic acid prior to clarification with conventional or state of the art cationic coagulation clarification or retention will improve the removal of resin acids and fatty acids.
Abstract: This invention relates to a lift to assist persons to stand or walk, where they have insufficient strength in their legs. The lift includes a supporting frame having a front portion extending in front of the person and side portions on each side.

Abstract: Systems for interchanging information, for example, obtaining cash from a terminal by use of a portable device such as a credit card are well-known but suffer from being vulnerable to fraud. In the invention a highly secure information interchange system is achieved by utilizing an intelligent card as the portable device which verifies that the terminal is a valid one and the terminal in turn verifies that the card is valid. Unauthorized users are screened out by means of a physical characteristic scan of the user such as a fingerprint which is then compared with comparable data stored on the portable device. If an invalid terminal attempts to communicate with the card, the card erases the data and programs from its memory. All programs and data in the terminal are stored in memory which loses its contents when power is interrupted, thus improving the security of the system by making unauthorized use of a terminal very difficult.
