Patent GB-179613-A (GB)
Title: Improvements in and relating to electric arc welding systems and apparatus therefor
IPC: B23K9/12
Filed: 1921-02-04
Abstract: 179,613. British Thomson-Houston Co., Ltd., (General Electric Co.). Feb. 4, 1921. Heating by electricity.-Consists in an electricarc welding system of the type in which the are is struck and the feed of the electrode and work are regulated automatically and which is adapted for use with different types of supply circuits. The movable electrode is fed by an electric motor which when feeding the electrode is subject to the voltage between the electrodes, but when reversed to withdraw the electrode to strike the arc is subject to the difference between the voltage of the system and the potential difference across the electrodes. Fig. 1 shows diagrammatically an arrangement in which the work 3 is traversed automatically by a screw 6 rotated by an electric motor 7. The electrode 1 is fed from a reel 2 by rollers 9, 10, the latter of which is connected by a brush to an intermediate main 15. The welding current passes from the main 13 through a resistance 58 to the work and through the electrode 1 to the main 15. The feed-rollers are driven by an electric motor 11, the armature of which is in a shunt across the arc. The field 12 is independently energized from the main 13. The main 15 when the machine is in use, is coupled by a switch 18 through an adjustable resistance 17, to the main 16. To start the machine the push-buttons 20, 21 are closed to complete a circuit between the mains 13, 16, through a coil 19 which then closes the switches 18, 22 and short circuits the button 21. The current now flows round coils 25, 28, 34. The opening of switch 33 cuts out the coil 38 so that the switch 37 remains in the position shown and the motor 7 remains at rest. The rising of the switch 26 opens the circuit through the armature of motor 11, but as the field 12 is strongly energized the armature rotates slowly to feed the electrode 1. When the latter touches the work the coils 25, 28, 34 are de-energized. The closing of the switch 24 sends a reverse current through the armature to reverse the motor 11 and raise the electrode 1 to strike the arc. The coil 38 is then energized to raise the switch 37 and start the motor 7 to feed the work. A vibrator 31, 32 and resistance 30 control the current through the field 12 to regulate the speed of the motor 11 and so keep the length of the arc constant as described in Specification 139,919. In a modification, a welding circuit of the balancing type as disclosed in Specification 133,439 may be used. In another modification a welding-generator of the type described in Specification 159,374, [Class 35, Dynamo-electric generators &c.] may be used. Specification 145.330 is also referred to.

Title: Improvements in or relating to implements for the displacement of crop lying on the ground
IPC: A01D78/10
Filed: 1964-01-31
Abstract: 1,043,134. Haymaking machines. PATENT CONCERN N.V. Jan. 31, 1964 [Feb. 6, 1963; Sept. 3, 1963], No. 4296/64. Heading A1F. A haymaking machine comprises a plurality of tined rotors 4, 5, 6 and 7 adapted to be driven from a power-take-off of a tractor via a shaft 53, the rotors being supported in pairs on two frame members 2, 3 which are pivotally mounted on a further frame member 1. The rotors comprise four arms 45 each having tines 47, 48, 49, 50, the tines 47, 48 being relatively thick for displacing heavy accumulations of crop but short so that they are out of ground contact and the tines 49, 50 being relatively thin but long for contacting the ground. The drives for the rotors 4, 5 are derived from a shaft extending along the interior of frame member 2, this shaft also serving to drive through bevel gears and universal joints a shaft extending along the interior of frame member 1 which in turn drives a shaft in frame member 3 for the rotors 6, 7. The tow bar 81 is connected to the frame member 2 for pivoting in a vertical plane, the amount of pivoting, in the working position shown, being restricted in one direction by a lug 80 on the frame moving in a slot on the tow bar. Each frame beam 2, 3 can have limited pivotal movement with respect to the frame beam 1 about pivots 13 set in a U-shaped bracket 10 to accommodate for undulations in the ground but can be locked rigid with the beam 1. For transport the beams 2, 3 can be swung through 90 degrees relative to the beam 1, the beam being locked in position by a locking pin 28 on an arm 26 engaging in an aperture in the beam 1 and the beam 2 being free to pivot with respect to the beam 1 for steering purposes. During this relative movement of the beams, the beams 2, 3 turn about a longitudinal axis relative to the beam 1 whereby the tines are lifted clear of the ground. The machine can be combined with a tractor and a mower arranged so that as the mower cuts one swath, the machine engages the two previously cut swaths. In this combination the machine can be replaced by a drum tedder.

Abstract: 1,209,683. Photo-electric monitor of machined parts. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. Jan.30, 1968 [Jan. 31, 1967], No.4760/68. Heading G1A. In a method and apparatus for checking a surface of a machined part, in a series of moving parts, as regards its position and its smoothness, a light is focused on the moving surface, the reflected light is monitored as regards intensity, and an accept or reject signal is developed for sorting purposes. The surfaces a. b. c. d, of parts P Fig. 1 on a transparent conveyer which may be linear or rotary are monitored by light conveyed by fibre optics 9 from a common source 11, the light being focused by lenses 2 on to the planes of the desired respective surfaces and the reflected light being deviated by devices 3 on to photo-cells 4. The reflected intensity depends on the position of the surface relative to the source focus and the photo-cell output provides a signal which can be analysed to give surface level, roughness, and length. The reflected beam may be arranged to fall on two photo-cells by means of a halfsilvered mirror; the cells being behind a pair of apertures placed one in front of and one behind the focal points of the beams, so that a differential arrangement can be applied to detecting the position of the inspected surface. A circuit using a number of these two-cell stations for separate tests is described with reference to Fig. 5 (not shown), and they are used to control relays whereby the accept or reject signal is applied to the sorting device. One circuit may include a resonant circuit tuned to a desired cut-line frequency to provide the smoothness monitor. The workpiece may be accepted through a gating arrangement which functions if a number of surfaces are satisfactory. Gates may also be made to respond to a counter counting a number of machined holes. The system may use sequential tests and have a reject arrangement operative after each test.
