Abstract: 1,199,735. Laminates including carbon fibres. ROLLS-ROYCE Ltd. 23 April, 1968 [16 May, 1967], No. 22542/67. Heading BSN. [Also in Division F1] A laminate comprises a plurality of layers of carbon fibre reinforced resin material, the fibres of all the layers being parallel, and a plurality of layers of a material having substantially isotropic strength and stiffness properties as compared with those of the fibre reinforced resin layers. As shown, six layers 16a-16f, each of resin, reinforced with a parallel array of carbon fibres, are arranged in three pairs, the pairs being interleaved with four layers 17a-17d of steel. The laminated material may be formed into a compressor blade for a gas turbine engine, Figs. 1 and 2 (not shown), in which case the individual layers may be of differing lengths and/or widths. Some of the layers, for example, may extend further towards the tip of the blade than others, Fig. 2 (not shown).

Abstract: 745,463. Stop mechanism. FAIRBAIRN LAWSON COMBE BARBOUR, Ltd. July 21, 1954 [Aug. 17, 1953], No. 22592/53. Class 120 (2). [Also in Group XXXVII] A textile drawing or like machine is provided with at least one rotatable drum-type switch adapted to be engaged by a sliver as it passes between the drawing and delivery rollers and arranged to open or close electrical contacts should its rotation cease. The making or breaking of the contacts is used to stop the machine. As shown, the switch comprises a central shaft 1 mounted by two insulating bushes in a tube 34 so that electrical contact can be established between the shaft and the tube by balls 17, 18. A ball race 8 is mounted on the tube 34 and has a drum 10 mounted thereon. Pins or vanes 15, 16 project inwardly from the drum to provide housings for the balls 17, 18. When the drum is being rotated by a sliver contacting its peripheral surface the balls 17, 18 are flung outwards by centrifugal force and there is no connection between the shaft 1 and the tube 34. Should rotation of the drum cease, however, due to the sliver breaking or bunching up at least one of the balls falls inwards and establishes contact between shaft 1 and tube 34 and completes an electric circuit through a connecting tag 7, sleeve 9 and bracket 12. The switch may be adapted to operate in a vertical position.

Abstract: 603,726. Automatic frequency-controlling systems. BELCHER, J. C. Sept. 12, 1945, No. 23519. [Class 38 (iv)] A method of stabilizing the output of a calibrated variable frequency oscillator A consists in feeding the signals therefrom, preferably after amplification by a buffer amplifier B, to a mixer C, where they are mixed with harmonics of stable oscillations from a low-frequency oscillator E, feeding the mixed output to a low-pass (audio frequency) filter F which attenuates all but one controlling lowfrequency of known value produced by the beating of the generator frequency with a harmonic of the oscillator E, and then, at G, mixing the controlling low-frequency with the output of a calibrated audio-frequency oscillator H which is set to produce zero beat therewith in the mixer, the output from the mixer G being fed to a frequency or reactance modulator I which, in turn, feeds its output to the tuned circuit of the signal generator A, thereby controlling or locking the resonant frequency of the signal generator. The final stabilized radio frequency oscillation is obtained from the buffer amplifier B.

In a rotary printing press having a swinging ductor roller between, and to one side of the common axial plane of, a fountain roller and a transfer or distributing roller, the gap between the latter being substantially less than the amplitude of swing of the ductor plus its diameter, and actuating means having a constant stroke being connected to the pivoted bracket or brackets on which the ductor swings, the ductor axis is adjusted in position with respect to the bracket or brackets to vary the contact with one of the other two rollers, and may be swung in an arc concentric with the axis of this roller to establish the desired contact with the other of the two rollers. As shown, each end of the shaft C of the ductor 3 is mounted in an eccentric bearing 8, Fig. 3, having pinholes 16 to receive an adjusting tool, and releasably clamped in a bracket 7 pivoted at its mid-point on a shaft D; a link 9 is pivoted at E to the lower end of the bracket and at F to a crank 10 on a shaft 11 given a constant amplitude oscillation by cam &c. mechanism; not shown; the shaft D projects from an internally threaded block 18 vertically adjustable in fixed guides 20 by a screw 19 (the axes A, B of the other two rollers being in the same horizontal plane). The links 9 are of length equal to the sum of the radii of the ductor 3 and roller 2 (e.g. the fountain roller), and the points F are arranged so that with the cranks 10 at that end of their oscillation to bring the ductor 3 into contact with the roller 2, and the centre lines of the pivoted brackets 7 vertical, the links 9 are inclined by the same amount as, but in the opposite sense to, the line BC. With this arrangement vertical movement of the pivots D will cause the shaft C to move in an arc concentric with the roller 2; thus, the accurate setting of the ductor relative to the roller 2 by means of the bearings 8 will not be disturbed when the pivots D are thus subsequently adjusted vertically, after the cranks 10 have been moved to the other end of their oscillation, to establish the correct setting of the ductor relative to the roller 2.
