Title: Apparatus for and a method of forming a continuous series of substantially parallel filaments or threads
IPC: D04H3/045
Filed: 1971-09-01
Abstract: 1354559 Producing weft arrays and fabrics reinforced thereby RENHURST INDUSTRIES Pty Ltd 1 Sept 1971 [4 Sept 1970] 40779/71 Heading D1R A weft thread array (which may 'be combined with one or two warp thread arrays to form a scrim or deposited as reinforcement on a backing layer) is formed by supplying continuous thread (filament or yarn) to a plurality of outlet points 42 around the periphery of one or both of angularly disposed wheels 21, 22, rotating said wheels in the same direction, gripping each thread in turn as the outlet point 42 to which it is supplied moves adjacent the periphery of the other wheel, drawing the filament or thread to span between the peripheries of the wheels as they rotate, and severing each length of drawn out filament or thread to provide a weft threads array. Preferably the periphery of each wheel contains equally spaced outlet points 42 interspersed with gripping devices 43, the wheels being out of phase by one interval so that each outlet 42 passes point 27 simultaneously with a gripping device 43. Threads 39 (preferably glass fibre yarns or fusible material) are drawn from bobbins 38 supported on tubes 37 which convey the threads through the wheel to tubes 41 which connect with outlets 42. As the outlets approach point 27 a blast of compressed air is applied to eject the thread ends. Each gripper 43 comprises a pair of fingers 44, 46, each having a sleeve 51. Finger 44 is fixed whilst finger 46 is biased into contact with 44 by spring 49 but is forced away from finger 44 for a portion of the wheel's rotation terminating at point 27 by the action of cam 52 or 53 upon cam follower 48 attached to finger 46. The weft thread array is cut by disks 56, spring biased against roller 60. As shown the cutting device is diametrically opposite adjacent point 27 in order to maximise the length of the cut thread. This length can also be varied by altering the angle between wheels 20, 21, the support frame 26 being pivotable for this purpose.  An adhesive coated base web (63, Fig. 11) may pass around roller 60 to pick up the cut threads (66). These threads may be laid in contact with each other or at a spacing determined by the rotational speed of wheels 20, 21 relative to roller 60 and by the number of thread outlets. Warp threads (64) may be laid onto the cut weft. Non-woven scrim may be produced by replacing web (63) by warps (67, Fig. 13, not shown), which may be coated with adhesive. Further warps (68) may be laid on top. Preferably the two warp arrays are staggered so that successive warps are above and below the weft layer, to give a "semi-woven" scrim. Fusible fibres may be heat-bonded.

Title: Improvements relating to the preparation of metal arsenides and/or phosphides
Inventor: ANDERSON JAMES THOMSON
IPC: C01B25/06
Filed: 1960-12-02
Abstract: Phosphides and arsenides of aluminium, gallium and indium, for use as semiconductors, are prepared by reacting the vapours of the volatile halides, excluding the fluorides, of these metals with vaporized phosphides and/or arsenides of cadmium and/or zinc, the reactants and unwanted reaction products being more volatile than any of the desired products. Gallium chloride is vaporized by heating to 150 DEG C. in a silicon boat and the vapour is carried by an inert gas into a silica reaction chamber maintained at 1000 DEG  C. Another inert gas stream carries zinc arsenide, produced by heating Zn3As2 to 850-900 DEG  C., through a second inlet tube into the reaction chamber, whereby gallium arsenide is deposited on the walls of the reaction chamber, zinc chloride and the surplus reactants being carried away by the combined gas streams to be condensed in a cooler part of the system. Excess GaCl3 and Zn3As2 still remaining in the product may be removed by soaking it in dil HCl, washing with water, and subsequently heating to effect volatilization. A halide which disproportionates to the metal and a halide which is non-volatile at the temperature of the reaction cannot be used, but one disproportionating to the metal and a volatile halide may be used, the metal produced reacting with the phosphide and/or arsenide as disclosed in Specification 949,945.

Abstract: 434,206. Colour photography. I. G. FARBENINDUSTRIE AKT.-GES., Frankforton-Main, Germany. Feb. 28, 1934, No. 6493. Convention date, Feb. 28, 1933. [Class 98 (ii)] In a process of printing a lenticular film by projection on a lenticular blank film, a diaphragm is inserted in the path of the light so as to appear at a distance from the original equal to that at which the multicolour band filter or its virtual image was spaced from the original during taking and at a distance from the copy equal to that at which the filter or its virtual image will be spaced from the copy during projection and the films are moved for printing each component colour record so that the line from the centre of the picture field to the centre of the corresponding filter strip coincides with the optical axis of the printing objective. In the form shown, one of the lateral images is being printed from the film A onto the film L, both the films having been turned round axes parallel to the lenticular elements, the line NH, EH joining the centres of the image fields to the centre of the filter strip H coinciding with the optical axis. If the embossed sides of the films are turned in the same direction the films A, L, are also turned in the same direction round their axes. Instead of a rotation the films may be moved in parallel planes. In Fig. 6 is shown the apparatus for carrying out the process. The original and copy film pass through gates 1, 2 pivoted at 3, 4 the position of the gates being controlled by arms 6 carrying bolts 7 moving in slots 8 in which they can be locked. Light from the source 9 illuminates a ground glass pane 10, and the film in the gate 1 and the image is projected on the film in the gate 2 by an objective 11 having a diaphragm 12, a shutter 13 being also provided. Specification 402,902 is referred to.

In a sawtooth waveform generator comprising a capacitor in series with a transistor, the waveform is made more linear by connecting an inductor in parallel with the capacitor, the resonant frequency of the circuit being less than the repetition frequency of switching pulses fed to the transistor. As shown, negative line or frame pulses are passed via an emitter follower 3 to render transistor 11 conductive, charging capacitor 17. At the end of each switching pulse the energy stored in circuit III is discharged into a load comprising deflection coils 25. The discharge is linearized by inductor 18, the linearity being further improved by a series circuit 20, 21, tuned to half the repetition frequency. The resonant period of capacitor 17 and inductor 18 is preferably twenty times the repetition period. Inductor 26 is included to avoid charge storage and temperature effects. Variable resistor 15 allows the effective load resistance to be adjusted when circuit I feeds camera tubes via lines of different length. Component values and waveforms are included.
