Title: Tyre inspection machines
IPC: G01N23/18
Filed: 1975-03-27
Abstract: 1511161 Tyre inspection machines USS ENGS & CONSULTANTS Inc 27 March 1975 [11 April 1974] 12979/75 Heading B7C In a tyre inspection machine, a tyre is moved along a support (i.e. rollers 27) into an inspection station where it is accurately located by sensing means. Subsequently means (i.e. flanges 35, 36 of spools 31, 32) are moved towards one another at identical speeds axially of the tyre to engage the tyre shoulders and position the tyre with its equatorial plane coincident with a predetermined plane. Then an X-ray source 83 is positioned to direct X-rays through the wall of the tyre, and the X-ray images may be presented for visual and/or automatic tyre inspection. The illustrated machine further includes bead spreaders 75. In operation, with the tyre in the inspection position the spreaders and X-ray source are lowered to the position of Fig. 16 prior to being positioned as illustrated in Fig. 2. The X-ray source is rotatable to three positions to direct X-rays successively to screens 91, 90, 92. The distances the spools 32 and flanges 35, 36 are moved are sensed, and control respectively the times of each energization of each of a plurality of stepping motors (not shown) for intermittently rotating the spools 31, 32 and the spreading apart of the tyre beads by spreaders 75. The image from each screen 90-92 are stored on one third of a storage tube for subsequent display of the complete tyre sector image or a television monitor. During such display the tyre is stepped and the images of the new sector are stored on a second storage tube. Whilst the completed image of the second tube is being displayed, the image of the third sector is being stored in the first tube and so on. A defective tyre is marked by manual operation of a marking device. The tyre may be rotated continuously where regularity of such a structure as the breaker is to be determined. In an alternative, automatic inspection mode the machine may include photocells programmed to signal variations in tyre density such as result from cords being too close or too far apart. In visual or automatic inspection, the intensity of the X-rays emanating from source 83 may be automatically varied so that the intensity of the beam after it has passed through the tyre may be maintained constant. Visual and automatic inspection may occur simultaneously. Reference has been directed by the Comptroller to Specification 1,420,527.

Abstract: 1467202 Frequency multipliers INTERNATIONAL STANDARD ELECTRIC CORP 1 April 1975 [10 April 1974] 13205/75 Heading H3T A circuit for producing a sinusoidal output which is a harmonic of an input square wave, comprises means C1, R1 for differentiating the input of U e  to produce a train of pulses, said pulses being applied to the bases of a pair of transistors Trs1, Trs2 of opposite conductivity type having their emitter-collector paths in series between the terminals of a D.C. source, a transformer having a primary winding divided into halves W1, W2, each of which is connected in the emitter-collector path of a respective one of the transistors, the transformer having a single secondary winding W3 tuned by a capacitor C3 to resonate at the harmonic frequency, and a capacitor C2 connected between the mid-point of the transistors and one terminal of the D.C. source. With the circuit shown, when the square wave goes positive Trs1 is turned on producing a pulse in W1 and charging C2; when the square wave goes negative Trs2 is turned on producing a pulse in the same direction in W2, charge being drawn from C2. Thus two pulses of the same polarity occur in W3, (a2), Fig. 2 (not shown), for each cycle of the input and consequently an even harmonic may be produced, the tuned circuit having a high Q. In another embodiment, Fig. 1b (not shown), the primaries W1, W2 are polarized so that alternate pulses of opposite polarity occur in W3, (b2), an odd harmonic being produced. In other embodiments, Figs. 3a and 3b (not shown), the emitters of Trs1, Trs2 are connected respectively to the +ve and -ve supply terminals, and the collectors are coupled together via the series combination of W1 and W2, separate differentiating circuits (C1<SP>1</SP>, R1<SP>1</SP>, and C1<SP>11</SP>, R1<SP>11</SP>) being provided for Trs1 and Trs2 respectively. As before the circuit may be arranged to produce either an even, Fig. 3a (not shown), or an odd harmonic, Fig. 3b (not shown). The D.C. supply may be either unbalanced, Figs. la, 3a, or balanced about earth, Figs. 1b, 3b, in the latter case C2 having one plate earthed. The capacitance of C2 may be either large so that its potential is almost constant, or small so that its potential changes considerably during each pulse.
