Inventor: ALLEN RONALD
IPC: G11B5/84
Filed: 1986-11-12
Abstract: A robotic method is disclosed for connectively inserting a plug into a central aperture on a blank disk, moving the plugged disk to a panel which is conveyed to a position for coating a magnetic material on series of mountes disks, demounting the disks from the panel, removing the plug from the each processed disk and returing the plug for reinsertion into a subsequent blank disk. The robotic system includes a series of cassettes (55, 56) holding blank disks which are ejected in seriatim from each cassette and plugged by manipulation of robotic arms at that cassette position. Each disk is transported by a robotic arm and inserted into a series of disk-holding apertures (11) in a carrier panel (10) and, after processing of multiple disks in the panel, the processed disks are removed from the carrier panel by the robotic arm to a second cassette position where the plugs (20) are removed from the processed disk and the plugs conveyed by a pair of robotic arms (40, 41) or by the robotic arm (50) acting in conjunction with an auxiliary robotic arm for reinsertion into other blank disks. Sensor means are provided for accurately positioning the robotic arm with respect to the position of the carrier panel to be loaded. The robotic arms may be pro­grammed to tilt the grasped disk and plug with respect to the carrier panel to facilitate insertion or removal of the disks into the carrier panel.

Abstract: A first of a plurality of nodes in a multiprocessor system transmits a data packet to a second of the plurality of nodes over a data channel when the first node detects a predetermined sequence of bits on a control channel connected therebetween. The data packet is preceded on the data channel by a header which includes a plurality of fields informing the second node of the beginning of the data packet, the length of the data packet and the sequence number assigned to the packet. The data packet is followed by a field which enables the second node to determine whether the data packet was received correctly. If the second node determines that the data packet was received correctly, the data packet is stored in the node and an acknowledgement sequence is transmitted to the first node over the control channel. However, if an error occurs during the transmission of the data packet, the protocol enters an error state by removing all signal information from the data and control channels. Thereafter, a recovery processor, which is associated with each of the plurality of nodes, analyzes the state of the nodes at the time of the error in order to determine which corrective action needed to recover the respective node. The data link protocol also facilitates the transmission of a data packet from a first node through an intermediate node to a final node without storing the data packet in the intermediate node.

Abstract: First and second co-located axially and circumferentially extending RF coils (10) are displaced spatially with respect to one another by 90 degrees so as to produce a pair of RF signals from the enclosed generally cylindrical volume which are in phase quadrature. Each of the coils includes four spaced-apart and generally parallel leg sections (L, to L 4 ; L' 1  to L' 4 ). The same coils (10) or one of them may also be utilized for transmitting NMR RF signals into the same volume. The coils have a common open-end through which objects to be imaged may be inserted and a common "closed" end for convenient location of RF coupling and feeding structures. Each of the coils (10) has an RF feedline structure (14, 16) which extends across a diameter of common closed end and the two feedline structures are disposed substantially perpendicular with respect to one another so as to minimize cross coupling. The feedlines are also spatially configured to faciliate mounting of associated tuning (Cp, C f ) and coupling (C 1 , C 2 , C a , C b ) capacitors. A fixed coupling "paddle" provides cancellation coupling between the coils and a movably mounted coupling paddle is arranged to provide variable amounts of cancellation coupling between the orthogonal feedline structures. The phase guadrature RF signals emanating from the pair of coils are preferably amplified before being combined in a 90° RF hybrid circuit.

Abstract: Methods and apparatus for electrochemical extraction of a ligand such as molecular oxygen from a first fluid environment and for release of a ligand such as molecular oxygen, as well as ligand carrier compounds therefor comprising linear, pentadentate polyalkylamines and transition metal ions. The carrier compounds have the general formula:
     where:
     M is an electrochemically active transition metal ion;   R, and R 2  are each organic groups including a nitrogen coordinated to M;   m, n, o, and p are each 1, 2, 3, or 4; and   
     X is selected from the group consisting of 2,6-pyridyl, 2,6-piperidyl, 2,5-pyrrolyl, 2,4-imidazolyl, substituted heterocyclic amines, -O-, -S-, -P-, and -N-R, where R is hydrogen lower alkyl, or aralkyl. 
     By providing an electrocatalyst capable of rapid electron transfer and having an electropotential less than that of the carrier compound, low energy electron transfer between the carrier compounds and the electrode of the electrochemical cell is achieved. The use of electrodes having catalytically active surface sites leads to efficient electron transfer between the carrier compounds and the electrodes of the electrochemical cell, resulting in lower energy consumption and/or increased oxygen output.
