Title: Method and device for selfregulated welding in the manufacture of longitudinally welded metal tubes
IPC: B23K13/02
Filed: 1969-09-29
Abstract: 1287453 Automatic control of welding DALMINE SpA and G DRECHSLER 29 Sept 1969 [28 Sept 1968 9 Nov 1968 16 Nov 1968 21 May 1969] 47798/69 Heading G3R In a system for producing metal tubing by longitudinal seam welding a plurality of ratios between electrical signals corresponding to welding variables are compared with predetermined ratios and any differences added algebraically to control the welding. In Fig.1, metal 1, formed into a tube by applying pressure to rolls 5, is fed past seam welding electrodes 9, 9' supplied from an electrical source 8. An electrical signal dependent on the pressure applied is produced at 7. An electrical signal dependent on the rate of feed, is produced at 4 by a tachometer alternator 3. An electrical signal dependent on the temperature of the weld is produced at 17 by the effect on the mutual inductance of water cooled transformer windings 15, 16. Electrical signals dependent on the welding voltage and total current are produced at 10 and 11 and an electrical signal dependent non welding current in zones adjacent to the welding zone is produced at 13 by the effect on a magnetic detector 12. By multiplying the voltage signal with each of the two current signals, values of total and non-welding power are obtained so that, by subtraction, the welding power is obtained. In one control system described ratios of the pressure, welding power and temperature signals relative to the rate of feed signal are compared with pre-set optimum ratios and any differences combined in adjustable proportions to control welding. In a modification, ratios of the welding current and temperature signals relative to the rate of feed signal, and the ratio of the welding power signal relative to the pressure signal are compared with pre-set optimum ratios and any differences combined in adjustable proportions to control the welding current.

Title: Electrophotographic copier
IPC: G03G21/00
Filed: 1968-10-09
Abstract: 1,236,056. Photo-electrostatic copier. ADDRESSOGRAPH MULTIGRAPH CORP. Oct. 9, 1968 [Oct. 16, 1967], No. 47881/68. Heading G2H. An apparatus for the production and development of electrostatic images and their transfer to copy sheets uses an organic photo-conductive layer on a drum or a continuous belt which allows rapid recycling without plate fatigue and without the need for plate cleaning. A continuous belt 24 carrying an organic photo-conductive layer 26, mounted on rollers 28, 30, 32, 34 is sensitized by corona charger 70, receives the originals to be copied through guide 14, is imagewise exposed using lamps 86 or 88, passes through a magnetic brush developing station 104, and meets copy sheets 16 at a transfer station 120. The developing station 104 is insulated from the rest of the apparatus so that it may be raised to a potential of the same polarity as the charge image equal to or slightly greater than the charge potential in the exposed areas of layer 26. Alternatively the conductive support of the belt may have a potential of the opposite polarity but of the same magnitude. By this means the long 'toe' portions of the light decay curves (Fig. 1) are effectively eliminated and also residual toner on the layer 26 from a previous cycle is reattracted to the brush while toner transfer to the image areas proceeds. Transfer of the developed image to the copy sheets 16 is effected by means of a conductive rubber pressure roll 124 operating in conjunction with roll 30. The pressure between the rolls, preferably in the range 2-100 pounds per lineal inch, is adjustable by a spring 142 and adjusting nut 144. Substantially all of the material image is transferred and the amount that remains does not interfere with the charging or exposure steps. Other types of developing means may be used e. g. cascade development using conductive glass beads.

Title: Calibration and proving of meters
IPC: G01F25/00
Filed: 1967-10-20
Abstract: 1,200,796. Photo-electric calibration of meters; measuring fluid-flow. ESSO RESEARCH AND ENG. CO. Oct. 20, 1967 [Oct.31, 1966], No.47887/67. Headings G1A and G1R. A meter for measuring volume of liquid or gaseous flow is calibrated by passing the fluid leaving the meter through a pipe whose volume between the stations is accurately known and comparing the meter reading accumulated during the time a fluorescent marker takes to flow between the stations with the known volume. The volume of the pipe can be calibrated in a similar way against a standard meter. The fluorescent marker is a gas or liquid injected at one station and detected at the other. In Fig. 1 either a standard meter 16 or a meter to be calibrated 34, which deliver via generators 18 and 35 pulses per incremental volume flow, are connected to counters, 20 and 21. Counter 20 starts counting and counter 21 stops when a sample of fluorescent marker is injected at 29 into the flowing fluid stream which dispenses in the stream during its passage down the pipe section 39. Detector 31 upon detecting a predetermined level of fluorescence at station 32 stops counter 20 and starts counter 21, then stops 21 when the fluorescence falls below the predetermined level; The volume of the pipe section 39 between stations 29 and 32 equals the meter reading of counter 20 plus half that of counter 21. The pipe section can thereby be calibrated against the standard meter 16 then the uncalibrated meter against the pipe. The control circuitry 27 automatically causes another injection of fluorescent marker and restarts counter 20 when the detected fluorescence falls below the predetermined level. The average of a series of runs is then taken.

A circuit-breaker tripping and reclosing arrangement comprises a current sensing means 101 inductively coupled to a or each phase of a distribution network, time delay circuits 103, 104 to provide a signal after time delays of differing lengths, a pick-up circuit 102 for preventing operation of the time delay circuits until the current in the network reaches a predetermined magnitude, a tripping circuit 105 connected to the time delay circuits for tripping the circuit breaker 106, 107 and means for disabling the delay circuit 104 having the shorter time delay. In the arrangement shown, the tripping circuit 105, in addition to tripping the circuit-breaker, steps a programmer 108 to its next step. On the opening of the circuitbreaker 107 a close circuit 110 becomes operative and under the control of a reclose timing circuit 111 controls the time elapsed before the energization of the circuit-breaker closing coil. At the same time the close circuit 110 enables a timing circuit 113 to time out to render a reset circuit 114 effective to reset the programmer 108. If however a fault persists in the network, the pick up circuit 102 prevents the circuit 114 from resetting the programmer 108. Switch means 116 determines the number of fast timedelay tripping operations and a switch means 117 determines the number of reclosing operations which will occur before lock-out is reached. The arrangement is a static circuit using various semi-conductor devices and is described in detail in the Specification.
