Title: Automatically controlled change-speed device for lathes and like machine-tools
IPC: G05B19/06
Filed: 1945-04-24
Abstract: 607,688. Driving machines. SOC. E.P.I.C. (ELECTRICITE PRODUITS INDUSTRIELS & CHIMIQUES). April 24, 1945, No. 10290. Convention date, Jan. 20, 1943. [Class 83 (iii)] A self-acting spindle speed control device for a lathe or like machine tool which may be manually operated if desired, is characterised in that a control member is connected to the turret or other tool-holder so that setting the tool into the working position operates electromagnetic change speed gearing to give the spindle speed most convenient for the particular tool operation. The arrangement includes a transformer 24, the primary circuit of which receives current from a network and the secondary circuit of which comprises two windings, one energizing a series of contactmaker coils 6<SP>11</SP>-17<SP>11</SP>and 20, and the other feeding current to a rectifier 25 delivering direct current to electromagnets in a speed change gear-box B. The latter is connected to a series of push-button controls 6-17 with which are associated indicator lamps 6<SP>1</SP>-17<SP>1</SP>, this enables manual operation of the speed changes if desired. Automatic speed control is derived from a rotating arm 2 mechanically coupled, in the example described, to the turret of an automatic lathe, this arm makes contact with a number of studs 3 corresponding to the different tool stations of the turret. Wander leads 4 connected to the contact studs at one end may be inserted in sockets 5 in the switchboard secured to the headstock according to the set of speeds required to machine a particular work-piece. A push-button 18 is provided for starting up the automatic operation and this immediately disengages any previously engaged speed. A braking pushbutton 19 is provided for stopping the machine when required. The wiring is also arranged to prevent the simultaneous switching on of more than one speed and is effected by feeding current to a relay 21 and electromagnet 23 for releasing all the speed change switches. Normally, the current in this circuit is too small to operate the relay. When, however, two or more push-buttons are inadvertently pressed, two or more of the resistances R1-R13 are short-circuited and the current is then sufficient to operate the relay, the braking relay is energized at the same time to stop the machine

Title: Apparatus for sensing a misalignment between an object movement and a beam of radiation
IPC: G01D5/26
Filed: 1969-02-27
Abstract: 1,261,924. Measuring alignment photoelectrically. PHILIPS ELECTRONIC and ASSOCIATED INDUSTRIES Ltd. Feb. 27, 1969 [March 2, 1968], No. 10549/69. Heading G1A. The misalignment between the direction of movement of an object relative to a direction defined by a collimated beam of radiation is measured by rotating a plane parallel transparent block in the path of the beam and detecting the intensity variations of the beam, the detector or a member in the light path being attached to the object. In the arrangement of Fig. 1, the block 7 is mounted with its rotation axis just outside the boundary of the beam 2 from a laser 1. When the detector 2 attached to the object under investigation (a slide 4) is on the axis of the beam, its output, as the block is rotated, gives a symmetrical waveform of intensity against angle of rotation of the block, Fig. 2a (not shown), which can be displayed as an oscilloscope. If the axis of movement of the slide 4 (and thus the detector) moves off the beam e. g. such that its axis 6 is angularly displaced relative to beam 2, the detector output is asymmetrical, the amount of asymmetry being representative of the displacement. In other embodiments, the detector is fixed, the object under investigation having mounted thereon a rectroreflector and lens (13, 12). In one, this reflects the beam back via a plane mirror (14) to the detector, Fig. 3 (not shown) and in the other back via a half-silvered mirror (18) in the beam from the laser.
