Title: Method and apparatus for recording phase-modulated control signals
IPC: G11B20/20
Filed: 1966-01-31
Abstract: 1,098,048. Programmed control. BENDIX CORPORATION. Jan. 31, 1966 [Feb. 8, 1965], No. 4199/66. Heading G3N. A reference signal and at least one command signal, which are phase-modulated, are recorded on separate tape channels and during playback control signals are generated from the recorded signals, a compensation for skew being effected by recording on a separate tape channel a signal having a known phase displacement with respect to either command or reference signals and detecting during playback variation from the known phasedisplacement and modifying the control signals in accordance with the variation. Information relating to the desired motion path of an output member is coded in digital form on a punched tape which is passed through a reader to produce axis command pulse signals which are recorded on a magnetic tape, together with a composite reference signal, comprising a square wave sequence with superimposed 90‹ phase shifted marker pulses, and a pulse signal derived from the square wave and designated as a skew signal. During playback, as shown, a magnetic tape 38 is read by playback heads 60 and a reproduced composite reference signal 62 is fed to a discriminator 78, Fig.5 (not shown), wherein the square wave and marker pulses are separated. The outputs of the discriminator flip-flops 84, 88 energize stator windings 96, 98 of a resolver 100, a manually positionable rotor of which, having windings 102, 104, is connected to the stator windings 106, 108 of a feedback resolver 110 the rotor 112 of which is positioned by an X-axis servomotor 114. The square wave output of the rotor 112 is fed through a filter 115, passing the fundamental frequency, to a detector keyer 118, Fig. 7 (not shown), having as a further input square wave signals derived from a flip-flop 120 triggered by the reproduced X command signal on line 64. The detector keyer 118 determines the phase relationship of the inputs and develops an output signal, proportional in magnitude to the deviation of phase angle from 90‹, which is along the X-axis. The error signal is fed through a summing resistor 126 and filter 128 to a servoamplifier 130 controlling the servomotor 114. A signal, compensating for the skew of the tape 38 across the playback heads 60, is fed to a summing resistor 132, to modify the error signal to amplifier 130, from a detector-keyer 134, responsive to the 90‹ reference signal pulses from flip-flop 88, and pulses from a flip-flop 136 triggered by the skew signal on line 70. The detector-keyer 134 develops additional skew compensating signals 140, 142 which together with signals on lines 66, 68 are fed to the Y and Z axis positioning arrangements.

Title: Improvements in flash removing apparatus
IPC: B23K37/08
Filed: 1952-02-18
Abstract: 703,214. Trimming welded joints. BAILIS, R. Feb. 18, 1952, No. 4287/52. Class 83 (4). [Also in Group XXIII] Apparatus for removing flash from both sides of the weld seam of two butt-welded metal sheets 18, 20 comprises upper and lower rotary grinders 10, 12 mounted in housings 22, 23 vertically adjustable, by screws 30, on a carriage 28. The carriage 28 has lateral tongues 32 received in grooves 34 in a base housing 36, and is moved relative to the housing by a screw 44 operated .by a handwheel 47. The rotary grinders are driven by motors M which may be electric but are preferably air motors, the supply of compressed air being controlled by a valve 76 operated automatically or by a foot pedal 78. The sheets 18, 20 are clamped between a stationary lower jaw 52 secured to the housing 36 and a movable upper jaw 54 carried by a lever 60 pivotally mounted at 68 on the housing 36 and actuated by a double-acting air cylinder 80 under the ,control of valve 83 operated by a handle 86. To ensure tight clamping the jaw 54 is secured to the lever 60 by pivot pin 62 so as to seat itself properly on the sheet; it is tightened on to the sheet by turning screw 66. The jaws 52, 54 are each in two pieces with the juxtaposed edges bevelled to accommodate the grinders. The valve handle 86 is operated by a rocker arm 89 pivoted at 90 and loaded by spring 92,; the other end 94 of the rocker arm has a set screw 96 to co-operate with the rear edge 98 of the carriage 28; when the carriage 28 is in its narrowest position the valve 83 is thus automatically actuated to raise the jaw 54, but as soon as the carriage 28 is moved forwardly from this position the spring 92 contacts the valve 83 to lower the jaw 54 to damping position. After grinding one seam, the sheets are moved, so as to bring the next seam into correct position to be ground, by auxiliary clamping jaws 100, 102 carried by a sliding carriage 104 having a pinion 110 meshing with a fixed rack 108 and operated through gears 110b, 112 by a handwheel 114; movement of the carriage 104 is limited by adjustable stops 116, 117.

Title: Improvements in autogenous welding and blowpipes therefor
IPC: F23D14/54
Filed: 1920-02-12
Abstract: 162,431. Percival, S., (Davis-Bournon- ville Co.). Feb. 12, 1920 Uniting by fusion. - In butt-welding by fusion the longitudinal seams of prismatic or other tubes, barrels, or plates, &c., the portions to be united are heated and fused progressively by a collection of jets extending lengthways and spread transversely of the seam. In one form, a tube a, Fig. 2, with edges held open in proper alignment by a rib or one of a pair of rolls and closed 'by rolls b, is passed beneath an oxy-acetylene or like torch having two rows of jets e parallel to the welded seam, and set back from the edge of the seam and comprising prebeating-jets and jets for fusing the seam at f, the fused metal forming a wave g behind the jets and -piling up at the end of the ridge h. The rows of jets parallel to the welded seam in this form divarge from the converging parts of the open seam and the preliminary jets thus act on or about the edges of the seam. The inner cone of the flame is used for heating and fusing the seam, and the envelope which is of lower temperature and has a reducing action is divided, part entering the interior of the tube to prevent oxidation and to preheat or anneal the tube and part playing round the exterior of the tube. Separate annealing of the tube after welding is thus avoided. In a form in which the edges of the seam are passed through the apparatus in a closed condition the rows of jets are parallel to and on opposite sides of the seam. One or more central jets may be placed in rear of the other jets for smoothing down the wave of molten metal. In a further modification the rows of jets may converge as shown in Fig. 19, or the initial jets may be parallel to the seam and the latter jets converging. In another modification, pairs of jets set back from the seam may alternate with central jets. A further modification shows a form in which the initial jets are set back further from'the seam than the other jets. As shown in Fig. 17, two rows of initial jets T are used. The jets may be replaced by a pair of longitudinal slits or by a series of transverse slits as shown in Fig. 22. Jets set bach from the seam may also be arranged behind the central jets if desired, for heating the metal without fusing it to assist the central jets. If desired, more ahan two rows of jets or slits may be used. The preheating jets may be supplied with cheaper gases than the oxyacetylene mixture. Either the work or the torch may be moved to effect the welding.

Abstract: 1463115 Temperature sensitive magnetic switch CHEMETRON CORP 31 Jan 1974 04475/74 Heading H1N [Also in Divisions H3-H5 and A4] Heating operations in a microwave oven are controlled by a ferromagnetic sensor 308 which is removably positioned in the oven to cooperate with a detector 924, 926 mounted outside the oven cavity, the detector 924, 926, reacting to the loss of magnetism of the sensor 308 when it has absorbed sufficient microwave energy to exceed its Curie point and causing a control circuit to de-pressurize the oven. The sensor 308 is mounted in one comer of a rectangular tray 300, which may be segmented as shown, which is guided into its correct orientation in the oven cavity by an angled member 109 secured to the floor 108 of the cavity. The sensor 308 is in the form of a ferrite disc and is positioned over the top of a magnetic reed contact unit 926 (Fig. 5) when the tray is in place. The contact unit 926 rests on a plastics plate 928 which in turn rests on a magnetic plate 930 for concentrating the flux of a permanent magnet 924 in the contact unit 926 and causing the unit to close. When the ferrite sensor is overhead the contact unit 926 and below its Curie point it shunts the flux away from the contact unit 926 so that it opens. When the sensor 308 exceeds its Curie temperature, the permanent magnet flux closes the contact unit 926 with consequential de-energization of the oven. The magnetic reed contact unit detector may be replaced by a detector comprising a pivoted adjustably spring-biased permanent magnet carrying a mercury switch (Fig. 14, not shown). The permanent magnet is attracted to the ferrite sensor on the tray so long as it is present and below its Curie point. Once the Curie point is exceeded, the magnet pivots away from the sensor and closes the mercury switch.
