Title: I/o system for off-loading operating system functions
Inventor: PEACOCK RICHARD B
IPC: G06F12/0866
Filed: 1987-11-03
Granted: 1992-08-11
Abstract: ABSTRACT        An  I/O processor  and a memory where a number of queues or linked control blocks (IOCB 1 and IOCB 2)  are maintained   for   each  device  connected   to   the   I/O processor.   There is a control block for every operation to be performed by a particular device.  A device may be an I/O bus, a controller unit or a peripheral unit.  The I/O processor maintains a table of different combinations of buses and peripheral controllers that may be used to access   a   given  peripheral  unit   and   selects  that combination with the least frequency of use.  A portion of main memory is assigned as a single cache so that when the I/O processor accesses a data segment in one of may disk drives,  the entire disk drive track (59a,  b & c)  being accessed is read into the assigned cache portion of main memory since following data requests would most likely be made therefrom.  The I/O system is provided with a task control processor which provides for the scheduling of the different  central  processors  for  the  highest  priority processes to be run. When an initiate I/O operation is detected,  the respective processor is  released from the process that it is currently running and can be assigned to the next highest priority process.  When the requested I/O  operation  has  been  completed,  the  Task  Control Processor is signalled so that the Task Control Processor can put the requesting process back into the priority list of processes to be run by the main central processors.

Title: Apparatus for separating a contaminated portion of bulk material from a flow of bulk material
Inventor: SANDI ROLAND
IPC: B07C5/34

Granted: 1992-10-06
Abstract: TITLE OF THE INVENTION            APPARATUS FOR SEPARATING A CONTAMINATED PORTION OF BULK MATERIAL FROM A FLOW OF BULK MATERIAL            ABSTRACT OF THE DISCLOSURE     Contaminated portions of bulk material are removed from a flow of bulk material with the aid of a flow or drop pipe in a casing that is movable back and forth between a discharge position and a normal flow position.  The flow or drop pipe is equipped with baffle plates or bends for sufficiently retarding the free flow of the flowable bulk material to enable a detector and control mechanism to respond to the presence of contaminations and to then move the casing for the discharge of a contaminated portion of bulk material.  The movement of the casing of the flow pipe assures that a slide gate or a portion of the casing closes the upper inlet to prevent the further flow of bulk material when the casing is in a discharge position.  Due to the retardation of the free flow of the bulk material, it is possible to con-struct the apparatus with a substantially shorter structural height than was possible heretofore. 2164/ar

Abstract: METHODS AND SYSTEMS FOR RETROGRADE PERFUSION IN THE BODY FOR CURING IT  OF A DISEASE OR IMMUNE DEFICIENCY                          Abstract Catheter feedback methods and systems are disclosed for optimizing the  infusion of a drug,  such as a chemotherapeutic agent via retrograde perfusion through the venous side of the vascular network to a selectively determined portion of a solid tumor.  Monitoring and regulatory capability are provided for controlling the outflow of the drug and thereby for controlling the dose rate, the duration of exposure of the drug, the leakage factor, and the level of systemic toxicity, all critical factors in the successful treatment of solid tumors.  A feedback loop for practicing the method comprises two concentric  balloon  catheters  capable  of  extensive maneuvering and selective placement within the venous drainage of the vascular system, creating a third in-vivo space for repeated perfusion of the selected portion of a diseased organ as often as desired, providing maximum exposure of the chemotherapy to the tumor with minimum exposure to any other portions of the patient's body.

Title: Triaxis stabilized platform
Inventor: PADERA CHARLES J
IPC: G12B5/00
Filed: 1988-02-03
Granted: 1994-10-18
Abstract: TRIAXIS STABILIZED PLATFORM            ABSTRACT OF THE DISCLOSURE    A stabilized platform having five degrees of freedom utilizes a platform supported on a base by a spherical bearing which permits movement about roll, pitch and yaw axes.  A triaxis torquer has a non-magnetic stator depending from the platform, permanent magnet rotors disposed on the base which produce a magnetic field through the stator, and a set of electrical windings attached to the  stator. Energizing the windings selectively produces torque in roll, pitch and yaw.  A mirror gimbal and drive system on the platform provides movement in elevation of a mirror.  A motor is provided for rotating the base in azimuth relative to its mounting in a vehicle or the like.  A set of rate gyroscopes mounted on the platform and a set of resolvers provide rate of movement of the platform and gimbal, and position information to a servo system which controls the torquers and drive systems to stabilize the platform in roll, pitch and yaw, and to position the mirror in elevation and azimuth.  Laser and infrared optical devices may be mounted on the platform and coupled by the mirror to a desired line of sight.

Granted: 1992-05-12
Abstract: MIXING APPARATUS AND METHODS OF FABRICATING SAME         Abstract A mixer which provides axial flow in a non-uniform flow field, such as may be established by gas which is sparged into a medium being mixed in a tank, and provides large axial flow volume without flooding and withstands variable loads on the blades thereof, thereby providing for reliable operation.  The mixer impeller is made up of paddle shaped blades, which near their tips (e.g., at 90% of the radius of the impeller from its axis of rotation) are of a width at least 40% of the impeller's diameter.  The blades also having camber and twist.  They are formed by establishing bending moments which form the blades into sections which are curved and flat, with the flat sections being at least in the center area of the base of the blades.  The hub for attaching the blades to the shaft of the mixer has radially extending arms with flat surfaces.  The base of the blades are spaced from the shaft to define areas therebetween.  These areas are reduced in size, thereby limiting the passage of sparging gas between the blades and the shaft and the strength of the coupling between the blades and the shaft are enhanced by backing plates of width greater than the width of the arms,  These backing plates are fastened between the arms and the flat sections of the blades.  Bolts extending through aligned holes in the arms, backing plates and blades provide strong and secure attachment of the impeller blades to the shaft so that the impeller will operate reliably in the environment which provides variable loads on the blade.
