Abstract: A process for the production of alumina by the Bayer process includes a precipitation process having an agglomeration stage and a growth stage. In the agglomeration stage, selected process parameters are controlled to limit the bound soda content of the slurry, whilst still maintaining conditions for high yield. In the growth stage, selected process parameters are controlled to controll the soda pick-up during growth so that a continuous decrease of soda content is obtained. Preferably, the growth stage is divided into a number of separate precipitation vessels and the temperature drop from one precipitator to the next is from 1 to 3 °C. The temperature of the liquor leaving the final precipitator is preferably about 55 °C. The agglomeration stage is preferably operated at 75 - 85 °C.

Abstract: The total alkalinity of an aqueous metalworking fluid is monitored and controlled by a continuous titration method that continuously supplies a stream of the metalworking fluid, at a known, controllable flow rate, to a flow through chamber having therein a static mixing element. Simultaneously and separately a stream of acid titrant, of known acid concentration is injected into the flow through chamber at a known controllable flow rate. The acid titrant and metalworking fluid mix and react in the chamber and the reacted metalworking fluid exiting the chamber passed over the tip of a pH electrode. The pH of the reacted metalworking fluid is continuously monitored and the output of the pH electrode used to adjust the flow of acid titrant to the chamber until an endpoint pH value (typically a pH of 4) is reached. The total alkalinity is then determined from a) the known flow rates of the aqueous metalworking fluid and acid titrant and the known acid concentration of the titrant or may be determined from calibration curves for XY coordinate plots of volume of titrant vs known metalworking fluid concentration.

Abstract: An electronic golf scorecard has a casing which can be opened to expose a keypad and a display.  The keypad can  be used to enter players' initials, handicap data and each player's score on individual holes during a game of golf.   Circuitry within the scorecard, processes and stores the entered data and displays appropriate information so that each player's score can be visually determined.  The scorecard keeps a cumulative total of the players' scores after each score entry.  When the game of golf has been completed, the net scores for all players are automatically calculated and are displayed by selecting the appropriate key on the keypad.  Unused memory locations can be used to keep track of other golfing data such as for example, the number of putts per hole, the holes won or lost during the match or the stroke holes in the match, to name but a few.  This other golfing data can be displayed by selecting appropriate keys on the keypad.

Title: Draw tape machines and methods

Filed: 1996-12-11
Granted: 2006-02-14
Abstract: This invention pertains to draw tape equipment, and methods for incorporating draw tapes into plastic and like bags. In general, a continuous plastic web is slit at a slitting station to form layers, and respective free edges. The web then passes to a hole forming station where holes are formed in the top and bottom layers adjacent the free edges. After holes are punched, edge regions of the top and bottom layers are separated from each other, followed by forming of hems in the separated layers at hem forming stations arranged in parallel with each other. Concurrent with forming of the hems, continuous draw tapes are fed to the hem forming stations and the hems are formed about the draw tapes. The formed hems, with the draw tapes incorporated therein, optionally pass through transverse stretching apparatus and/or through electrostatic pinning apparatus and/or through first temperature control stations where the temperature of the plastic web is controlled to a desired temperature before hem sealing. The formed hems are then sealed to the main bodies of the respective top and bottom layers. The sealed hems optionally pass through second temperature control stations to cool the web. The edge regions of the layers are then rejoined, in face-to-face relationship with each other.

Abstract: This invention is directed to the repair of cast composite vehicle wheel hubs used specifically on trucks.          Such hubs typically have a plurality of spokes extending from a boss with webs extending between the spokes.  The hubs are cast of composite metal alloy material which cannot be repaired by conventional welding methods due to the metallurgical make-up of the hubs.  Damaged outer spoke portions are repaired by fitting an annular band by removing a portion of each outer spoke surface.  The band is secured to the spokes by using an intermediate bracket of weldable material secured by mechanical fasteners to the spokes of the hub.
