Title: Process for the recovery of an organic acid from the manufacture of a cellulose ester
Inventor: JONES STEPHEN C
IPC: C07C51/48
Filed: 1996-04-24
Abstract: The present invention is directed to a process for the recovery of an organic acid.  The organic acid is generated from the manufacture of a cellulose ester.  The first step of the process is to remove the organic acid from the manufacture of cellulose ester.  The acid is in the form of a weak acid stream comprising of the organic acid and water.  The weak acid stream is resolved, via a solvent extraction, to form an extractor overhead stream and raffinate stream.  The raffinate stream comprises solvent, water, and alcohol.  The alcohol is produced in the recovery process by hydrolysis of the solvent after the solvent extraction.  The raffinate stream is resolved into a overhead stream and a bottom stream.  The overhead stream comprises water, alcohol, and solvent.  Excess organic acid is added to the overhead stream to form a feed stream.  The feed stream is catalyzed, via ion exchange resins,  whereby a portion of the alcohol is esterified to the solvent.  The solvent, thus produced, is recycled into the recovery process.

Abstract: Process and Apparatus for a fully automated magnesium melt system.  Raw magnesium ingots are moved through a preheater chamber heated by radiant heat panels where they are thoroughly dried by being controllably heated to a temperature range of about 150°C to 250°C preferably 200°C to 225°C before they are introduced into a melt cell also referred to as a furnace.  The ingots, are monitored for temperature by an infra red temperature sensor or a direct contact type thermocouple and this determines whether the ingot is ready to be charged into the furnace.  A furnace metal level probe monitors the metal level and a control unit causes ingot charging as determined by a process level set point or temperature overshoot.  The melt cell, or furnace uses a closed loop P.I.D. (Proportional Integral Derivative) equation that is enhanced in a PLC (Programmable logic controller) program by introducing variables that are interactive with an ingot being charged to the furnace metal bath, the die cast machine being started and placed into automatic cycle or semi-auto, and also by which furnace control mode the operator has selected via the operator computer interface. The two furnace control modes are run mode (production) and idle mode (non-production, weekend). There are two zones of heat in the furnace with each zone supplied by its own 3 phase zero cross fired silicon controlled rectifier firing boards which are gated by A 4-20mA gating signal. This controls how much the SCR's are allowed to conduct. The amount of error between the metal bath set point and the actual metal bath temperature automatically determines how much of the 4-20mA gating signal is required to maintain the predetermined metal bath temperature.  Liquid magnesium is transferred from the furnace to the die cast machine shot sleeve pour hole by a siphon transfer tube which has two sets of electrical heating elements. The melt cell upon receiving a request from the die cast machine for material will, as long as all conditions are met in the melt cell PLC program, allow the transfer tube to lower to the die cast machine pour hole. The transfer tube valve then opens for the length of time set by the operator via the operator computer interface.  Providing all safety conditions are met and sensor activated for signal to PLC.  Upon completion the valve closes and the transfer tube raises to its home position to be ready for the next cycle.  The signal to the die cast machine that the pour is complete is given as soon as the valve closes and the tube begins to raise. Interactive communication between the die cast machine computer, a control computer and other monitoring or remotely located computers provide complete process control and information.          This provides total control of the temperature of the magnesium at all times, for safe operational quality and cost effective casting.

Inventor: COLLIER ALAN
IPC: B01J19/12
Filed: 1996-12-03
Abstract: A device for improving combustion efficiency of carbon based fuels and decreasing resulting pollution emissions by treating the fuel before it enters a combustion device. This is accomplished by applying a strong magnetic field across the fuel flow line close to the point of combustion. The magnetic field is applied by extending the polarity of a strong, cross-polarized, permanent magnet with steel polarizer bars. The bars are situated parallel to each other with the fuel line running in between. This magnetic polarization device can also be used to apply a magnetic field to a water line to dissolve and prevent scale build up inside pipes, valves, water heaters, etc. This device requires no external power source and is maintenance free.

Abstract: A piston velocity control and stability control system is provided for a combustion powered tool having a self contained combustion engine. The system includes a ring that may be adjusted relative to exit ports in a cylinder of the combustion engine. The ring includes openings which may be incrementally aligned between a completely exposed, and a substantially closed position relative to the exit ports. Displaced air volume within the cylinder exits through the exit ports as a piston advances down the cylinder, and the velocity of the piston will be greatest when the exit ports are completely exposed. User initiated reduction of the effective size of the exit ports by adjustment of the ring will reduce piston velocity as described per application. A nosepiece used to guide the driver blade and position the blade over a fastener is isolated from the cylinder so that the nosepiece remains stable relative to the workpiece upon combustion and until the driver blade strikes the fastener.
