Title: Recycling process, apparatus and product produced by such process for producing a rubber extender/plasticizing agent from used automobile rubber tires
Inventor: MUNGER JOSEPH H
IPC: C08K5/00
Filed: 1991-07-19
Granted: 2006-02-28
Abstract: A preferred embodiment of the process and apparatus for recycling used automobile rubber tires is described in which small pieces of rubber tires are progressively fed into a vertical reactor of the counter-flow type in which the material progressively descends downward through the reactor with process gases passing upward through the downwardly descending material to decompose and volatilize the rubber material. At the lower portion of the vessel, oxygen-bearing gas is injected into the reactor to burn a portion of the rubber carbon to generate hot combustion gases that ascend upwardly to pyrolitically decompose the rubber pieces, and to volatilize such material.      The amount of oxygen is controlled in an oxygen-deficient manner to maintain the temperature in the combustion zone at a temperature of less than 500 °F. The gases and volatilized rubber materials and oils are removed from the reactor at a temperature of approximately 350 °F at an elevation below the top layer of the rubber pieces in a high velocity stream to maintain the oils entrained in the air stream. The air stream is directed into condensers for condensing the rubber process oils. The raw rubber process oils are subdivided to obtain a residue heavy fraction rubber oil material having a flash point of greater than 340 °F and greater at one atmosphere and a boiling point of greater than 450 °F at 20 mm Hg for use as an extender/plasticizing agent in rubber compounding in which such agent has shown to exhibit unusual and unexpected results. The oxygen-baring gas is initially maintained at a temperature of between 40 and 60 °F and is then passed through the condenser as the cooling agent before it is passed into the reactor. Consequently, the air-bearing gas serves as the cooling agent in the condenser and also as the oxidizing agent for burning a portion of the carbon in the reactor to generate the desired temperatures.

Abstract: The most commonly available operating systems over the last two decades have had a monolithic kernel architecture. These operating systems often employ windowing systems or graphical user interfaces (GUI's) but adding complex functionality to the monolithic kernel itself. Microkernel operating systems offer a superior architecture, but heretofore, where not available with an effective GUI. While monolithic operating systems support complex instructions such as "drawing"or managing an input device, microkernel architectures seek to operate with a minimal set of primitives, delegating the more complex tasks to external processes. The invention provides an effective GUI for managing the interaction of a plurality of programs, by defining a three dimensional "event space" in which the programs operate. Each program has a set of characteristics, which define its location in the event space. This paradigm allows a microkernel operating system to manage the programs by managing this small set of characteristics.

Title: Microprocessor-controlled strobe light
Inventor: KOSICH JOSEPH
IPC: H05B41/34
Filed: 1994-04-12
Granted: 2002-04-02
Abstract: A flash tube power circuit includes a switch which in a first position regulates the storage over time of energy in a first energy storage device and in a second position allows the transfer of energy from the first energy storage device to a second energy storage device. A microcontroller receives the input voltage and then samples and digitizes it for input into a lookup table. The microcontroller repeatedly cycles the switch between flashes by controlling the time the switch is in its first position. The lookup table output provides the signal for determining the time the switch remains in its first position. The time interval from the last flash controls the time the switch is in its second position. The cycling of the switch is controlled accordingly such that the second energy storage device acquires the predetermined amount of energy for the flash just as the triggering circuit is initiated by the microcontroller. Moreover, the microcontroller controls the switch in a way such that the time the switch is in its first position is maximized and the time the switch is in its second position is generally decreased relative to the time since the last flash. This helps to minimize the peak current drawn by the first energy storage device. In addition, the strobe light circuit is capable of determining if the input voltage is D.C. or is full wave rectified and controls the switch accordingly.
