The first spring mechanism (30A) includes at least one combination of two springs (31a, 31b) arranged in series with each other. The two springs (31a, 31b) have a different spring constant or a different maximum angular stroke. Thus, a spring constant (K) of the first spring mechanism (30A) changes at a predetermined torsional angle (ϑ R ) whereby the torque capacity of the flywheel is greatly increased.

Abstract: A conceptual decision analysis tool for production release planning displays management parameters and objectives and prompts the user to define priorities. This encourages the user to plan based on management criteria. The user keys in the priorities and the system automatically analyzes the impact of planned release on the manufacturing process using a simulation process and re-evaluates the order release priorities and sequence. This capability is used before any order is actually released to manufacturing. The system also provides the capability of analyzing the impact of the orders even after the user pre-sets priorities to release certain orders. The system calculates the revised sequence and produces impact statements on such management criteria as manufacturing throughput, work-in-process inventory and cycle time.

Abstract: Range and focus conditions are detected by comparing the current separability factor of a light beam impinging upon a detector (62) and the separability factor of the detector. Signals from independent portions (A, B, C, D) of the detector are processed to yield a given separability factor to the detector. When the light beam impinging on the detector has a comparable separability factor a zero signal results, other­wise signal amplitudes and polarities signify degree of differences in the separability factors which are relatable to range hence focus conditions. Detector output signals are normalized in an antithetical manner and then compared to a certain comparison of the separability factors of the detector and impinging light beam.

Abstract: A sheet feeder (10) has a supply station (16) wherein signatures fresh from the printing press are stacked. The stack is supported such that the signatures are in an arched, non-planar configuration. A sheet stripper (18) extracts signatures successively from the stack and feeds them in a constant stream to a transfer conveyor (20). The stripper grips the sheets with a suction device which applies a constant but locally intermittent vacuum. The transfer conveyor carries the signatures to a delivery station (22). The delivery station includes fingers (116) which arch the signatures. Arching the signatures in the supply and delivery stations prevents rolling of the signatures.

Abstract: In a metal vapor discharge lamp of the type comprising a translucent outer bulb (4) that houses an arc tube (1) and a starter which is connected in parallel to the arc tube (1) and which includes a nonlinear capacitor (2), at least one of the lead wires (9a,9b) of the nonlinear capacitor (2) is connected to a support line (10b) whose thickness is such that it does not obstruct the oscillation due to any electrostriction of the nonlinear capacitor (2) and such that it fuses whenever a large current flows through the nonlinear capacitor. Due to this construction, the oscillation of the nonlinear capacitor is not obstructed, so that a high-voltage pulse can be generated and the noise level lowered Furthermore, since the support line is designed to be fused by a large electric current, thus breaking the electric circuit, any burning of the ballast can be prevented.

Abstract: The floating point computation unit for providing a sign/­magnitude subtraction operation, uses propagate/generate logic (10, 11, 12) responsive to the subtraction operands (A and B) to produce intermediate and final propagate and generate outputs (P and G). First carry computation logic (13) is responsive to the final propagate and generate outputs (P and G) and to a carry-in bit (C₆₃) to produce final carry outputs (C₁₅, C₃₁, C₄₇) and a carry-out bit (C o ). The latter outputs are used (14, 15, 17) to produce a first subtraction result (R). Second carry computation logic (18) responds to the intermediate propagate and generate outputs (P and G) to produce second final carry outputs (C′₁₅, C′₃₁, C′₄₇). The latter outputs and selected intermediate propagate outputs (P) are used (19, 20, 21) to produce a second subtraction result ( -R ). The carry-out bit (C o ) then selects (22) one of the two subtraction results as the final subtraction result (R or  -R ). 
     The floating point unit can further normalize an exponent result in conjunction with a mantissa result which is formed as a plurality of data slices. The number of leading zeros in each data slice is determined and each number of leading zeros is subtracted from the exponent result to produce a plurality of subtracted results. One of the subtracted results is then selected as the normalized exponent result.

The ball and shaft are part of a removable bonnet (14) assembly with the ball inserted into the flow bore through an aperture (50) in the valve body. A one-piece seal (56) in the aperture provides a static seal between the valve body and bonnet and a dynamic shaft seal.
