Abstract: ABSTRACT DUAL PORT ACCESS CIRCUIT Two microprocessors, which may be operating asynchronously, share a random access memory (RAM) array; that is, at any one moment of time, either microprocessor can seek access to the RAM but only one of them can actually gain access at a time.  Priority of access to the RAM is controlled by a dual port contention-resolving access circuit which enables such access alternately to the two microprocessors when both are seeking (overlapping) access, subject to the stipulation when neither microprocessor is accessing the RAM that the very next access will be allocated by the circuit on a first-come first-served basis, and will be allocated to a preselected one of the microprocessors if both microprocessors will commence to seek access precisely at the same time.

Abstract: Abstract A switching network for selectively supplying current to a clamping capacitor comprises a pair of output transistors with outputs coupled to the clamp capacitor, a pair of control transistors respectively coupled to the output transistors, and a pair of equal value bias resistors included in output circuits of the control transistors for determining the bias of the output transistors.  When the control transistors conduct, the control transistors conduct equal output currents, equal currents flow in the bias resistors, and bias voltages developed across the bias resistors exhibit equal rates of change with a sense for rendering the output transistors non conductive simultaneously.

Abstract: PROCESS FOR THE PREPARATION OF     Abstract of the Disclosure A process for the preparation of 2-hydroxy-4-methylthiobutyric acid is disclosed.  2-Hydroxy-4-methylthiobutyronitrile is hydrolyzed with mineral acid to produce an aqueous hydrolyzate containing 2-hydroxy-4-methylthiobutyric acid and substantially free of unreacted 2-hydroxy-4-methylthiobutyronitrile and 2-hydroxy-4-methylthiobutyramide.  2-Hydroxy-4-methylthiobutyric acid is recovered from the hydrolyzate by extraction.  Extraction may be carried out without prior separation from the hydrolyzate solution of any substantial fraction of solids present therein, and 2-hydroxy-4-methylthiobutyric acid may be recovered from the extract by steam distillation.  The extraction solvent has a boiling point of between about 60°C and about 200°C, and the distribution coefficients for 2-hydroxy-4-methylthiobutyric acid between extract and raffinate, and between extract specimen and wash water, favor transfer to and retention of the acid product in the organic phase.

Abstract: Abstract of the Disclosure A multiple frequency adaptive filter system for filtering undesired periodic and/or correlated interference signals contained in the same frequency band as a desired input signal.  The filter system is capable of filtering at least two sinusoidal interference signals and incorporates a negative feedback loop having a trans-for function of that of narrow band-pass multiple filter.          The feedback loop using interference frequencies generates a corresponding interference enhanced output signal.  This enhanced output signal is combined with the input signal whereby to produce an error signal which corresponds to the desired signal contained in the input frequency band.          A double or quadruple filter system is also described as examples of the present invention.  The filter system is suitable for removing modulated sinusoidal interference and particularly for reducing TV co-channel interference.

Title: Shell for can
Inventor: BACHMANN HENRY C
IPC: B21D51/44
Filed: 1985-01-07
Granted: 1989-02-28
Abstract: The disclosure relates to a novel shell such as used in the manufacture of can ends, and to a method and tools for making such a shell. A non-circular blank having rounded corners is cut from thin metal. The blank is oblong in a direction transverse to the grain of the metal. A first set of tools separates the blanks and forms a substantially flat central panel and an upward-extending chuck wall about the edge of the panel to produce a partially formed shell. The junction area between said panel and said chuck wall has a relatively large radius of curvature at this time. A second set of tools forms in the blank a lip extending outward from the upper end of the chuck wall and generally parallel to said panel; then the panel and the chuck wall are separately gripped, followed by relative movement between the panel and the chuck wall while wrapping the junction area around a forming punch to form a panel wall in said junction area extending upward from the inner part of said chuck wall. Then the lip is formed into a curl edge section which ends in an inner curl diameter that is round and concentric with the chuck wall, and has progressively lesser radii of curvature from upper end of the chuck wall to the inner curl diameter. The resulting shell is characterised by a curl diameter being round and concentric with the chuck wall and essentially uniformly spaced therefrom, and by having an essentially constant thickness throughout the central panel, the panel wall and chuck wall and the curved section therebetween.

A coaxial coil heat exchanger is also provided, along with appropriate conduits for coupling the exchanger to the tank fitting housing and boiler respectively.

Abstract: ABSTRACT OF THE DISCLOSURE         A tool for positioning and retaining boiler pipe sections in aligned, spaced relation enabling the boiler pipe sections to be joined by heliarc welding incorporating a split block having opposed recessed therein which cooperate to define a passageway that is open at one side for receiving the adjacent ends of boiler pipe sections to retain the boiler pipe sections in alignment together with a spacing arrangement engaged with the opposed ends of the boiler pipe sections to retain the adjacent ends in adjustably spaced adjacent relation to enable heliarc welding of a portion of the adjacent ends of the boiler pipe sections.          After the initial heliarc welding process has been completed around a portion of the periphery of the boiler pipe sections, the block is re-moved and the heliarc welding is completed around the periphery of the boiler pipe sections with the radial depth of the heliarc welding being substantially less than the radial thickness of the boiler pipe sections thus leaving a peripheral groove which is filled with conventional resis-tance type welding material using conventional welding techniques.  The tool also includes an overcenter pulling device to pull the boiler pipe sections into aligned adjacent relation to that the block can be associated with the adjacent boiler pipe section.
