Abstract: 1,158,251. Cross-linked polymers. NATIONAL RESEARCH DEVELOPMENT CORP. 24 April, 1967 [26 Jan., 1966], No. 3481/66. Addition to 1,094,181. Headings C3R and C3T. A cross-linked polymer is obtained by reactin a polymer having aromatic nuclei with an aralkyl ether that comprises an aryl group or groups having at least two attached methoxymethyl groups, whereby methyl alcohol is eliminated and the polymer is cross-linked directly between aromatic nuclei with residues of the aralkyl ether, the reaction mixture also containing a minor proportion (relative to the aralkyl ether) of an aralkyl halide having at least two halogenomethyl groups (other than fluoromethyl groups) each attached to an aromatic nucleus. The polymer which is cross-linked may have been obtained in a preceding stage in which a compound having at least one aromatic nucleus is reacted with an aralkyl ether having two methoxymethyl groups each attached to an aryl group, the polymer being formed by elimination of methyl alcohol and aromatic nuclei being linked by residues of the aralkyl ether; a minor proportion of a di(halogenomethyl) aromatic compound may be included in the reaction mixture. A Friedel- Crafts catalyst may be included in the reaction. In examples cross-linked polymers are obtained by reacting p-di(methoxy) xylylene with terphenyl, and by reacting p-di(methoxy) xylylene with octaphenylcyclotetrasiloxane, p-dichloroxylylene and stannic chloride being added to both reactions. Other compounds having at least one aromatic nucleus from which the polymer may be prepared, are naphthalene, triphenyl phosphate, diphenyldiphenoxysilane, N-triphenyl borazole, diphenyl oxide and diphenylene oxide.

[Class 40 (iii).] A light-valve, of the kind in which magnetic polepieces define a light-transmitting slot across which a ribbon vibrates, is provided with a ribbon-supporting frame which is slidably carried by supports on a main frame which houses the magnetic structure of the valve. The main frame 1 supports the permanent magnets 2, 3, as shown by Fig. 1, which is a sectional view of a sound-recording apparatus including the light-valve of the invention. The magnets 2, 3 have polepieces 10, 11, respectively, provided with light-transmitting slots, and are located to form an air gap 12. The vibrating ribbon 40, Fig. 2, is supported on an auxiliary mounting frame 17 which carries a pair of ribbon-suspending bridges comprising supporting elements 20, 21 and 22, 23, on which are provided insulated locating pins 24, 25 and 26, 27, respectively. One free end of the ribbon 40 is secured to a tension spring 28 from whence the ribbon passes over the supports 20, 22 to a tension spring 29. The springs 28, 29 are adjustable by screws 30, 31 respectively, to give the ribbon the desired tension, and the spacing of the two parallel sections of the ribbon is controlled by adjusting screws 36, 37 which cause the supports 20, 21 and 22, 23, respectively, to approach or recede from each other. The springs 28, 29 are electrically connected to terminal plugs 32, 33. The frame 17 is provided with grooves 18, 19 which register with tongues 15, 16, respectively, provided on projecting arms 13, 14 of the main frame 1. The frame 17 has a rectangular portion 38 cut away to a depth sufficient to receive the pole-piece 1C as the frame 17 slides into position by means of the tongue and groove connection, when the plugs 32, 33 enter jacks 34, 35 on the main frame 1 to provide electrical connection for the ribbonoperating current. In an alternative construction, Fig. 5, the ribbon is supported by a slidable frame 70 of right-angled formation and the ribbon 71 passes from a tension spring 72 over a bridge 73, around an anchor plate 76, back to the bridge 73, and thence to a tension spring 77. The anchor plate 76 comprises two thicknesses 78, 79, Fig. 6, of duralumin and the thickness 78 has a projecting ear 80 to separate the two sections of the ribbon passing around the anchor plate. The bridge 73 is adjustable by screws 89, 90 to give the proper spacing of the sections of the ribbon and the tension springs 72, 77 are electrically connected to plug members 82, 83.

Each of the toothed number wheels 7 of the counter is coupled by teeth 1 to a wheel 1a which carries a cam 10 for operating contacts in a zero position; each wheel 1a carries a second registering wheel 1b. To set the selected number all wheels are first returned to zero position by a reset button 11; the wheels 1a, 1b can then be rocked by a lever 3a to a setting position. Here each of the pairs of wheels 1a, 1b can be stepped, to select the number, by a respective push-button 13 having a tooth 14 engaging pairs of teeth 8 on the two wheels. On release of lever 3a the wheels are returned by a spring to a position in which the wheels a are driven by the counter wheels while the wheels 1b are locked by abutments 16. Operation of the counter then causes wheels 1a to be stepped back towards zero when they actuate the contacts, while wheels 1b continue to display the selected count.

[Classes 40 (iii) and 40 (v)] A receiving arrangement for re-constituting pulse signals from two short marking pulses, Fig. 2, sent at the beginning and end of each signal pulse, comprises means for differentiating the marking pulses so as to derive from each, two differential pulses of opposite sign, Fig. 3, which are used to switch a device from one stable condition to another. As shown in Fig. 1, the received pulses are applied at 2, 3 to a differentiating circuit CR, and the differential pulses created across the resistance R are applied across the gas discharge tube 1 to the output terminals 5, 6. Normally, the tube is non-conductive ; it is triggered 'by the first positive pulse 27, Fig. 5, and its anode voltage drops to the level 30, where it remains until the arrival of the second negative pulse which blocks the tube. The anode voltage then rises along the curve 32 until the second positive pulse arrives and raises the voltage to normal 35. The tube may have its cathode biassed positively by a potential divider across the H.T. source, and it may be provided with a grid earthed through a resistance (Fig. 4, not shown). A resistance may be inserted between the anode and the upper end of the resistance R. In a modification, the differential pulses are applied to a pair of cross-connected hard valves arranged in known manner to have two stable conditions. The pulses may alternatively be arranged to control a mechanical polarized relay, the armature of which re-constitutes the pulses. Time-modulated pulses and synchronizing pulses in a television system may be sent and re-constituted by the circuit arrangements described.
