Abstract: New highly stable, elastomeric polymers are prepared under mild reaction conditions by chain extension of hydroxy-terminated liquid prepolymers such as polyalkylene oxides or polybutadienes with anhydrides such as tetrahydrofuran tetracarboxylic dianhydride, pyromellitic dianhydride, and benzophenone tetracarboxylic dianhydride. Chain extension at 60*C was provided in the presence of ferric acetyl acetonate as catalyst. The anhydride reactants are difunctional as anhydrides but tetrafunctional under conditions selected that lead to the reaction of all carboxyl groups. Thus, chain extension can be effected and then followed by cross linking via the residual carboxyl groups.

Abstract: Apparatus for welding a continuous insulated wire to numerous terminal pins of a circuit board, including a solid central electrode which presses the wire against the terminal pin to rupture the insulation and then weld the wire to the pin. A concentric second electrode has a pair of openings on diametrically opposite sides of the center electrode for closely guiding the wire across the face of the central electrode, one of the openings being a hole that completely surrounds the wire and the opposite opening being a slot which is open at its bottom end. After each point of the wire is welded to a terminal pin, the electrodes are lifted and then initially moved parallel to the axis of the wire portion that is welded to the previous terminal pin, and only then is the direction of electrode movement changed to carry it to the next terminal pin.

Abstract: A wideband digital pseudo-gaussian noise generator includes a register network comprising N multistage binary shift registers, with a total number of n stages. The input to each register is the modulo-2 sum of the outputs of at least two stages of the network, at least one stage being from a different register. The last stages of all the registers are used in controlling the inputs to the various registers. The characteristic polynomial of the network is primitive. The registers are clocked at a selected clock frequency. The output of one stage from each register is used to provide a binary voltage. The N voltages are summed and filtered to provide a pseudo-gaussion noise which is flat to about + OR - 0.5dB over a band equal to not less than one third the clock frequency.

Abstract: A solid-state triode is provided from a wafer of near-intrinsic semiconductor material sliced into filaments of rectangular cross section. Before slicing, emitter and collector regions are formed on the narrow sides of the filaments, and after slicing gate regions are formed in narrow strips extending longitudinally along the midsections of the wide sides of the filaments. Contacts are then formed on the emitter, collector and gate regions of each filament individually for a single filament device, or in parallel for an array of filament devices to increase load current.

Abstract: A compact, efficient, portable gas chromatograph system is disclosed in which the gas chromatographic column is disposed in a closed loop with an electrolytic hydrogen generator-separator. The output from the column containing the bands of analyzable materials dispersed in hydrogen carrier gas is passed through the tubular anode of the generator-separator. The hydrogen passes through the wall of the anode, across the electrolyte through the wall of the cathode and is collected and returned by way of the sample inlet to the inlet to the column. The analyzable material remaining stalled within the anode tube is swept into the detector by an auxiliary electrolytic hydrogen generator. A pressure transducer downstream from the anode develops an increased voltage signal in response to pressure drop which is applied to the controller for the auxiliary hydrogen generator to maintain a constant flow of hydrogen carrier gas within the closed loop circuit while also maintaining a flow of hydrogen sweep gas to the detector.

Abstract: Manganese bismuth films having improved characteristics for recording information by Curie-point switching, and especially for Curie-point recording of information in analogue form, can be produced by a vacuum deposition of Bi and Mn with an atomic ratio of Mn to Bi between 2 and 3.5 or 1.4 and 1.6, followed by a specialized heat treatment which includes very brief exposure to a temperature between about 275* and 300*C. Similar MnBi films can be produced more reliably and reproducibly if the initial Bi layer is annealed prior to deposition of the Mn layer. Such an annealing step renders most other factors of the processing relatively non-critical. Deposition of both initial layers is preferably carried out in a vacuum approaching 10 8 Torr, but at least traces of oxygen are then made available to the reaction site prior to the subsequent reaction of the Mn and Bi layers to form ferromagnetic MnBi.

Abstract: A priority interrupt system is disclosed comprising four registers including a push pop register. In the system, designed to accommodate up to n interrupts of different priority levels, each of the registers is of n bits, with the orders of the bits in the registers corresponding to the priority levels of the different interrupts. The highest order set bit in the push pop register indicates the priority level of the interrupt for which a sub-routine is being executed. Any lower order set bit indicates the priority level of an interrupt for which a subroutine has been previously started and thereafter interrupted to service a subsequently received interrupt of a higher priority level. The sub-routines are structured so that when a sub-routine is completed the highest order set bit in the push pop register is reset and the controlled computer automatically returns to complete the sub-routine associated with the next highest order set bit in the push pop register. The other registers are used to receive the various interrupts, to compare the highest priority level of any of them with the highest order set bit in the push pop register to determine whether or not the computer''s operation should be interrupted.

Abstract: Snake-cage resins are described where a phenol is absorbed as a counterion along the cationic sites of a crosslinked threedimensional matrix of a strong base anion-exchange resin initially in the hydroxide form. The absorbed phenol is then polymerized linearly by refluxing in 1:1 mole ratio with formaldehyde in aqueous solution, thus producing a ''''snakecage'''' configuration. Redox polyelectrolytes are derived from polyphenols, and resins capable of binding the monoborate ion from polyphenols or o-hydroxymethyl substituted phenols. The redox capacities of the polyphenolic resins were found to approach theoretical at between 5.1 and 5.4 meq/g. The hydroxymethyl substituted resins are certain of the polyphenolic resins show a marked specificity for absorption of borate ions.
