Abstract: 1285704 Line-followers BRITISH OXYGEN CO Ltd 30 Dec 1969 [30 Sept 1968] 46305/68 Heading G3N A path is unambiguously traced by photo-electric line-followers by the use of two or more complementary patterns which are traced in sequence. As shown, a Fig.3, the shape of a forme, to be used in cutting carton blanks, is represented by the heavy black lines and reproduced on three transparencies, each of which has a pattern comprising straight lines joined by radiused curves and denoted by different symbols. The transparencies are aligned by marks 30, 31 and, when superimposed, the patterns join outside the forme shape as at intersection 29. When scanning the prepared pattern the cutting device is inhibited during traverse of the portion of a pattern lying outside the forme by a photo-cell scanning a line parallel to the external portion. The output of a photo-electric scanning head, 18, Fig.1 is used to control co-ordinate positioning motor 10, 14, for a table 8 on which the patterns 2 are mounted, and supply encoders 20 producing position signals and inhibiting signals, which are fed to a punched or magnetic tape recorder 22. The signals stored in the prepared tape are used to control a laser cutting-machine grooving a plywood sheet. For production of a sheet containing a number of similar formes the signals from the tape-recorder 22 are fed into a tape-recorder 26 through a switching device 24 in synchronism with position transfer signals from a tape recorder 28. The produced grooved sheets are completed by inserting sharpened steel strips into the grooves.

Title: Apparatus for finding and drawing off the thread start of a textile bobbin
IPC: B65H67/08
Filed: 1962-12-11
Abstract: A pneumatic apparatus for withdrawing a length of yarn F from a bobbin 1 includes means that detects the presence of the thread in the air stream.  In Fig. 1 (not shown) the bobbin nose 2 is inserted in a suction tube 3 having a reverse bend.  The inner wall of the bend is slotted, as at 5, so that when a thread is drawn into the tube it will be drawn across the slot to deflect a feeler 6. Deflection of the feeler 6 energizes a solenoid 13 to cause a valve 19 to close the tube 3 and prevent further withdrawal of yarn from the nose 2.  The time constant is such that the free end of the yarn will be trapped by the valve 19 as it moves to its closed position. In a modified construction, Fig. 2 (not shown) the feeler 6 is replaced by an electrical condenser the capacity of which is varied by the presence of the thread.  In a further construction the feeler 6 is replaced by a photo-electric thread monitoring device.

In order to frequency modulate a laser for use in a transmission system as described in the Specification 1,218,421, an electro-optical crystal is placed in the path of the laser beam, the capacitance of the crystal being included with the capacitance of a voltage responsive variable capacitance element in the frequency determining circuit of an oscillator. The output frequency of the oscillator is a function of a signal applied to the variable capacitance element. The Colpitts oscillator of Fig. 5 includes in its tank circuit varactor diode 26b and electro-optical crystal 27, the latter being positioned in the optical cavity of crystal laser 33a. A modulating signal applied at input 30 varies the capacitance of varactor 26b and hence the frequency of the oscillator and the subsequent voltage across the plates of Pockels cell 27. The variation in refractive index of the Pockels cell results in frequency modulation of the laser beam in accordance with the frequency of the oscillator. The output 36 from the laser is transmitted to detectors by dispersion optics 37. Instead of providing a laser crystal with Brewster angle face 35 a Rochon prism may be employed, Fig. 6 (not shown). If crystal 27 is a phase-shifting cell the laser may be switched on and off, Fig. 7 (not shown).
