Abstract: Devices, methods, and computer program products providing user interfaces for visualization of user inputs may include generating a dynamic visualization interface for display, the dynamic visualization interface including indicia of selection, respective ones of the indicia of selection corresponding to variables associated with at least one contract; a plurality of increasing numbers corresponding to one or more of the indicia of selection; and a graphical indication that indicates a plurality of magnitudes of values that are dependent on the indicia of selection, monitoring one or more input devices of the computer system for adjustment to the one or more of the indicia of selection, and responsive to the adjustment to the indicia of selection, regenerating the dynamic visualization interface to reconfigure the graphical indication to adjust respective ones of the plurality of magnitudes of the values for respective ones of the plurality of increasing numbers.

Abstract: A process for annealing copper or copper-containing components, such as copper tubing, and/or for selecting copper with an appropriate grain size, such that potable water in contact with the properly treated and/or selected copper, has substantially decreased copper emissions, and may comply with ANSI/NSF 61. In one preferred embodiment, an ANSI/NSF 61-compliant water cooler may be constructed using a storage tank with wrapped copper water tubing treated and/or selected in this manner. The storage tank is preferably designed from non-copper components.

Abstract: The invention contemplates an improved poppet-type relief-valve construction which features an inlet-port configuration at upstream offset from the valve-closed seat region of the valve. To open the valve, a valve member must be moved by upstream pressure exceeding a predetermined threshold. This valve member integrally carries a specially profiled formation that (a) is upstream from the seat region and (b) coacts with a specially profiled region of inlet port. This action necessarily takes place upstream from the seat region and is such as to provide control of valve operation especially during that fraction of valve-member displacement that spans the "cracking" phase of valve operation. The net result is to avoid development of the "chatter" which customarily characterizes the "cracking" phase of valve operation.

Abstract: A jail-cell door is suspended from an overhead carriage, for horizontal displacement between closed and open positions, and an elongate slide bar has a horizontal lost-motion connection to the carriage. The slide bar mounts a reversible electric motor and is continuously engaged to the driven one of two rollers from which the carriage and its cell door are suspended; the shaft for the other suspension roller is journaled in the carriage. For driving the cell door in the door-opening direction, the outer lost-motion limit determines an expanded wheelbase of door suspension, and for driving the cell door in the door-closing direction, the inner lost-motion limit determines a slightly reduced wheelbase of door suspension. The slide bar carries cam formations at or near its respective ends for determining locking-bolt action only at the fully closed and fully open positions of the door, and a deadlock device is pivotally carried at one end of the slide bar, serving the door-closed condition.

Abstract: The invention contemplates a prestressed rolling mill incorporating a system of hydraulically operated load-transfer blocks, wherein the blocks are of unitary construction and bodily interposed between vertically opposed regions of upper and lower back-up roll chocks, at the respective inlet and exit sides of each axial end of the mill. Each load-transfer block is inherently self-adapting (at each of a plurality of force-application regions) to such small locally different deformations in the mill frame as result from the block's modulating contribution to net prestressing force; further, each load-transfer block includes its own hydraulic-control system with minimum-displacement actuators whereby a fast time constant of hydraulic response is achieved.

Abstract: The invention contemplates an electrically operated valve construction for control of fluid flow wherein an actuator module is adapted for detachable connection to a valve-body module which contains the valve member to be automatically positioned by a driver element of the actuator module. All electronic components for moving the driver element are self-contained in the actuator module, and these elements include a fluid-sensing transducer producing an electrical output, for closure of the control loop. The transducer has sealed exclusive exposure to fluid in the valve-body module via a special port within the confines of the interface between the modules, when the modules are assembled to each other; this port communicates directly with that part of the valve-body passage which is on the downstream side of the valve member.

Abstract: Rolling mills, especially for sheet metal, and also paper, rubber and similar rolling mills, require accurate control of the gap between the rolls since this determines the uniformity of the gauge of the material rolled by the mill. This invention provides a rolling mill with sensors that cooperate with the circumferential surfaces of the rolls, or rigid parts thereof, to detect relative movement of the rolls in directions that affect the roll gap and the gauge of the material being rolled. Response of the sensors operates a transducer to affect automatic correction of changes in the spacing of the rolls from one another.

Abstract: This gas pressure control system is intended primarily for testing gauges by providing an accurate static gas pressure over a wide range, preferably from zero to 10,000 pounds per square inch. The system is equipped with a pressure intensifier that operates automatically to raise the delivery pressure above the supply pressure when necessary. The supply may be a bottle of nitrogen under pressure of two thousand two hundred pounds per square inch, and the pressure intensifier is preferably a cylinder-and-piston motor-pump combination with a displacement ratio such as 70 to 1.
