Abstract: 1439277 Welding by pressure PRODUCTION TECHNOLOGY Inc 4 Sept 1973 [5 Sept 1972] 41579/73 Heading B3R In inertial friction welding, the relative axial movement between the workpieces after initial engagement is continuously monitored to determine the upset, the actual upset is continuously compared with an upset range known to provide an effective weld, the relative speed of rotation between the workpieces and the axial pressure under which they are engaged are similarly continuously monitored and compared with ranges known to provide an effective weld and if the upset, speed or pressure fall outside their ranges the welding process is interrupted. An inertial welding machine 11 has a rotatable spindle 13 in a frame 12 and a non-rotatable spindle in a movable tailstock 14. The spindle 13 carries a replaceable flywheel 18 and is rotated by an hydraulic motor 19 supplied from an hydraulic power source 21 and the tailstock is driven by an hydraulic ram 22. The hydraulic source 21 and the ram 22 are regulated by an automatic control assembly at 28 with an electrical power source 29 including manually operated switches to initiate and terminate welding operations. Transducers 31, 32 and 33 monitor axial upset, relative rotating speed of the workpiece and axial pressure between the workpieces and signals therefrom are conditioned by analog to digital converters 34, 36, 37 and a computer input logic interface 38 for transmission to a digital computer 39. A signal corresponding to each of the monitored conditions is instantaneously displayed on an oscilloscope 41 and a permanent record is provided by digital tape recorder, typewriter or digital recorder and a computer output logic interface 43 operates lamps 44, 46 and 57 to provide instantaneous indication of quality. The computer 39 can interrupt operation of the machine when operating parameters indicate an unsatisfactory weld. Information including time of commencement of welding, time at which upset pressure is developed and time at which weld is completed is delivered to the computer 39 and may be used to reset or adjust the machine control for a new operation. The shield 61 of the oscilloscope has dashed lines 62, 63, 64 which indicate an acceptable range for signals corresponding to speed, upset and pressure.

Title: Superposed sheet detection
IPC: B65H7/12
Filed: 1972-09-12
Abstract: 1396560 Feeding sheets XEROX CORP 12 Sept 1972 [16 Sept 1971 21 Oct 1971] 42325/72 Heading B8R [Also in Division G1] In apparatus for monitoring the thickness of successively conveyed sheets of material, e.g. in a printing press or a copy reproducing machine, signals representing the thickness of the corresponding sheets are generated and an initial one of the signals is compared with each successive signal. In a copy reproducing machine, Fig. 1 (not shown), sheets from a stack are conveyed to the machine via a thickness monitoring station. The monitoring station shown in Fig. 2, consists of a fixed roller 42 which carries a belt for conveying the sheets to the machine, and a rotatable member 101 which rotates anticlockwise to allow a sheet through the space between the roller 42 and member 101. The member 101 co-operates with a strain gauge 105 as shown, the gauge being arranged in a D.C. bridge circuit, Fig. 3, In an alternative, Fig. 4, a light source 110 co-operates with a photo-resistor 111 so that its resistance varies with the position of impingement of light thereon. In further alternatives, a variable capacitor or variable inductor may co-operate with member 101, in which case an A.C. bridge is utilized, or a rotary potentiometer may be used, or the strain gauge may co-operate with any suitable device responsive to the thickness of sheet material. As shown in Fig. 3, the bridge output is connected to a switch 308 which may contact either a terminal 309 or a terminal 310. Upon detection of the leading edge of the first sheet conveyed to the machine, e.g. using a mechanical switch or a photo-cell, a switch control 318 causes switch 308 to contact terminal 309, the bridge output, which represents the thickness of this first sheet, then being stored at 311. The detection of the leading edge of the next sheet then causes switch 308 to contact terminal 310 and switches 315, 317 to close for a preset time. During this time the bridge output, which represents the thickness of the next sheet, is compared with the stored signal in a comparator 316. If the difference does not exceed a threshold, monitoring of the next sheet proceeds as above. However, if the difference does exceed a threshold, indicating that a sheet is too thin, too thick or comprised of superposed sheets, a switch 319 is operated which causes the sheet or sheets to be rejected and a switch 313 to be closed whereby the storage device is discharged. This completes a cycle, and a new cycle may then be initiated. Means are provided in the machine for detecting whether the first sheet supplied thereto is composed of superposed sheets whereby a switch 314 is closed to discharge the storage means. The output of the bridge may be applied to digital circuitry, Fig. 5 (not shown), for comparing the thickness signals.
