Title: Tool for toquing and crimping
IPC: F16B19/05
Filed: 1972-01-25
Abstract: 1344776 Riveting HUCK MFG CO 25 Jan 1972 [4 Feb 1971 14 Sept 1971] 3538/72 Heading B3U A nut torquing and crimping tool comprises a plurality of crimping jaws 32 mounted in a collet 26, a draw bar 34 having one end connected to the jaws for axial movement of the jaws relative to the collet, and a rotatable housing 62 connected to the other end of the draw bar 34 in such a way that rotation of the housing relative to the draw bar causes the draw bar to move axially. In operation a rotatable power tool is applied to the housing 62 via the hexagonal end 78 and, due to inertia and friction, the housing will, intially rotate relative to the draw bar 34. The relative rotation causes the jaws 32 to grip the nut because the collet 26 is moved forwardly relative to the jaws due to the screw threaded engagement of the draw bar with the housing. As the jaws grip the nut, the force required to rotate the draw bar 34 relative to the housing 62 increases resulting in the entire tool rotating and the nut being threaded on the bolt. As the nut is tightened against the workpiece, the torque required to turn the nut further increases so that, on increase of torque at the end 78, the housing 62 is again rotated relative to the jaws 32. The alternative sequence of nut running and crimping will continue until the material of nut is crimped into the threads of the bolt after which any further increase in torque results solely in a crimping action. The amount of crimp is controlled by the amount of relative axial movement between the draw bar 34 and the housing 62, the latter amount being adjustable by means of an annular bushing 80. In a second embodiment (Fig. 6, not shown) the relative axial movement is effected by a camming action. In a third embodiment (Fig. 7, not shown) the relative axial movement is effected by a helical recirculating ball assembly (122) and the torque is applied via a planetary gear assembly.

Title: Fractionator control system
IPC: C07C67/00
Filed: 1966-01-27
Abstract: 1,102,393. Fractionating columns, automatic control. FOXBORO CO. 27 Jan., 1966 [2 Feb., 1965], No. 3810/66. Heading B1B. [Also in Division G3] In a control system for a fractionator, the feed rate is measured, the feed composition is analyzed, and the material balance resulting from changes therein is computed. The results of the computation are used to control the distillate flow rate, thereby maintaining the desired material balance. As shown, fractionator 10 has a fixed heat input, feed 11 containing variable percentages of propane and isobutane. Voltage signals on leads 17, 18 associated with analyzer 16 respectively represent the concentrations of propane and isobutane, these signals being converted to current signals by units 19, 20. Feed 12 has a constant composition containing a known concentration of isobutane and a negligible amount of propane. Flow rates of feeds 11, 12, are measured by meters 23, 24, having outputs proportional to the square of the flow rate which are passed through square root extractors 25, 26. The signal representing isobutane concentration is multiplied by a constant in unit 27 and is summed by unit 29 with the signal representing the concentration of propane in feed 11. The summed term is multiplied by the signal representing the flow rate in feed 11, and the resultant signal is applied to lead-lag unit 34. The signal representing the flow rate in feed 12 is multiplied by a constant and added to the signal at input 33 to unit 34. An isobutane analyzer 40 on side stream 13 provides negative feedback to unit 34, whose output is subject to delay compensating for the lag between feed composition change or flow change and the resulting effect upon the distillate output. In addition, output 37 is modified dynamically to compensate for the difference in response between a feed change and a distillate change. The output of unit 34 regulates flow controller 43 associated with flow meter 45.

Title: Method of charging constant volume explosion chambers particularly of explosion turbines and explosion turbine plants
IPC: C22B4/04
Filed: 1937-02-09
Abstract: 476,001. Gas turbine plant. HOLZWARTH, H. Feb. 9, 1937, No. 3824. [Classes 110 (ii) and 110 (iii)] [Also in Group XII] Air and gas for a constant volume explosion chamber are compressed in rotary piston compressors. When the air and gas are compressed in more than one stage, rotary piston compressors are used for the last stage, and turbo-compressors for the earlier stages. The quantity of air and gas delivered may be regulated by varying the speed of the turbocompressors and by synchronizing the rotary piston compressor with a rotary distributer associated with the combustion chamber described in Specification 8578 /07, [Class 110]. Air and gas are compressed in turbocompressors 18, 19 and 20, 21 and delivered to rotary piston compressors 15, 16 which delivers to a gas turbine 17. The turbine exhaust passes to a turbine 22 driving the stage compressors 18, 20 and thence to a heatexchanger 25. Feedwater for a vaporizer 27 is heated in the exchanger and is further heated in the jacket of the turbine 17. Steam so generated passes to a turbine 31 which drives the stage compressors 19, 21. The primary regulation of the plant is effected by controlling the steam passing to the turbine 31. Steam in excess of the requirements of turbine 31 passes to a turbo generator 33. The vane pumps 15, 16 are driven by an electric motor 35 which is synchronized with an electric motor driving a rotary distributer. Fig. 1 shows the disposition of the ports 4, 5 and vanes 3 in the rotary piston compressor.
