Title: Phosphonitrile polymers
Inventor: COATES HAROLD
IPC: C08G8/00
Filed: 1962-12-07
Abstract: Condensation polymers of good thermal stability are obtained by heating a cyclic aroxylhalophosphonitrile, PnNnXx(OR)y Wherein each X is F, Cl or Br; R is an aryl or substituted aryl group; n is an integer from 3 to 17 and x and y are integers such that x+y=2n and 2\sEx<y, with an organic polyhydroxy compound in the presence of a hydrogen halide acceptor.  A precondensate is first formed at 100 DEG to 250 DEG  C. or at the boiling point of a high boiling solvent and may be converted to the fully cured polymer by heating to 200 DEG  to 300 DEG  C. The precondensate may be purified by solvent extraction. The aroxyhalophosphonitriles may be prepared as described in Specification 1,013,463.  Preferred polyhydroxy compounds are polyhydric phenols and fluorinated aliphatic polyalcohols, many examples of these and other polyols being given.  The precondensate or a solution thereof may be used to form a laminate or impregnate a porous material and is then cured in situ.  In examples cyclic tetraphenoxydichlortriphosphonitrile is condensed with (1) diphenylolpropane, (2) hydroquinone, (3) 1,5-dihydroxynaphthalene, and (4) 2,2,3,3,4,4-hexafluoropentane-1,5,diol and cyclic tetra-)beta-naphthoxy)-dichlortriphosphonitrile is condensed with (5) diphenylpropane and (6) hydroquinone.

Abstract: 1,187,100. Coated lamp bulbs. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 23 Sept., 1968 [12 Oct., 1967], No. 46589/67. Heading B2K. [Also in Divisions C1 and H1] An electric discharge lamp comprises a fused silica envelope including having a transparent protective coating on the envelope interior consisting of aluminium oxide or boric oxide which has penetrated at least partially into the silica surface. The coating may be formed by heating the envelope surface to 800 to 1200‹C while exposed to a moisture free aluminium or boron halide vapour, alone or with hydrogen, or to a boron hydride vapour, the subsequent aluminium or boron deposition on the envelope surface producing discolouration thereof. The surface may then be heated in an oxidising atmosphere (e.g. air, oxygen or water vapour-inert gas (e.g. Ar) or N 2  mixture) to at least 800‹C until the discolouration is removed. The Al may be liberated from the vapour due to disproportionation (of aluminium monobromide for example), due to thermal dissociation (e.g. dissociation of boron halide, aluminium monobromide and boron tribromide at 1000‹C and boron from diborase vapour at 500‹C) or due to reduction (e.g. aluminium or boron trihalide with hydrogen).

Abstract: 1,160,318. Packaging seeds. WALDO ROHNERT CO. 30 Oct., 1967 [28 Dec., 1966], No. 49213/67. Heading B8C. [Also in Division D1] In manufacturing a seed tape from a tape of water soluble material the tape is initially moistened along at least one edge margin on one side of the tape to make it slightly tacky, seeds are deposited on to the tape at spaced intervals, the tape is closed on itself and adhered to itself by its own tackiness to encapsulate the seeds therein. The tape may be moistened over its whole surface so that each seed adheres to it. In the arrangement shown tape 10 of polyethylene oxide is drawn from reel 11 over a roller 26 and passes through a moistening device 27 and thence through a trough shaped cupping member 35 which folds the tape into a V formation. The tape in V form then passes beneath a dispensing station 40 which drops seeds at spaced intervals on to the tape. The tape then passes through another shaping member 41 which is more U-shaped than V-shaped and then between discs 12, 13 which seal the edges of the tape together. Discs 12, 13 also serve as means for pulling the tape through the apparatus and a counter 47a may be associated with one of the discs for measuring the length of completed tape. From the discs 12 and 13 the finished tape 14 is taken-up on a core 48. The dispensing means 40 consists of a rotating head 50 from which project a number of arms 51 each having at its end a nozzle 52 which is changeable. The arms are connected to suction means as they pass over and dip into a hopper 53 containing seeds so that each nozzle 52 picks up a seed and carries it around until it is over the tape 40. At this position the arm 51 is connected to atmosphere so that the seed is released on to the web. Between the seed dropping position and the seed picking-up position, the arm 51 is connected to a pressure source to clear the nozzle. The hopper 53 is vibrated to prevent formation of furrows in the seeds therein.

Abstract: 1,084,656. Semi-conductor switching circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. Nov. 22, 1965 [Nov. 23, 1964], No. 49554/65. Heading H3T. [Also in Division G4] Each stage of a counting chain has two semiconductor elements Ta, Tb, connected in series which have the property that they change from a high ohmic or non-conducting state to a low ohmic or conducting state when the voltage across them exceeds a threshold value and that they change back when the current passing through them falls below a low limiting value of current intensity. In the form shown when in one of the stages, e.g. S1, Ta and Tb are conducting, the voltage of 80 v. at source E1 results in a voltage of 70 v. at D1 in stage S1 and a voltage of 40 v. at F1. When a counting pulse of 30 v. is applied at A the voltage at F1 increases to 70 v. and consequently renders Tb in stage S2 conducting, this then decreasing the voltage at F1 to a lower potential so that To also conducts. The capacitor Ca has a value such that the point D2 is kept at a low potential long enough for point B to drop to a low potential to revert the elements Ta and Tb in the first stage to their non-conducting state.

Abstract: 1,081,169. Automatic alignment control. HEINZ MAHLO. Dec. 7, 1964 [Dec. 10, 1963], No.49626/64. Heading G3R. [Also in Division G1] Apparatus for detecting and tracking marks on webs of material e.g. textiles, paper or foils, involves a periodic circular scan across the mark and its surroundings by a detector element. The mark may be represented in the case of fabric web by a missing warp yarn or by a coloured yarn, seams &c. and is arranged to be parallel to the direction of movement of the material. In the described embodiment, a light source is arranged above the web 2 (Fig. 1) and the detector arrangement 4 mounted below on a spindle 5. The output of the detector gives an indication of how far displaced it is from the line of the mark 3 and is fed to a control circuit 7 which actuates the motor 6 to drive the spindle 5 and relocate the detector to line up with the mark. The detector element 4 includes a photo-cell (9, Fig. 2, not shown) arranged at the bottom of the hollow shaft (86) of a synchronous motor, which shaft is rotated about its own axis and carries a plate 8a having a pair of reflecting surfaces (10, 11) in the form of a bar prism. Thus, as the shaft rotates, that part of the light beam from the source, which is incident on reflector (11), in effect rotates about the axis of the shaft, such that light incident on the cell (9), which may be fixed, represents a circular scan by the cell. This scan may coincide with the mark on the fabric, in each case a pulse being transmitted to the control circuit. When the cell is lined correctly under the mark, pulses are obtained regularly, each half cycle of rotation of the shaft Figs. 3a, 4a, 5a (not shown), but if the cell is displaced by a small amount, two adjacent pulses followed by a long interval, are periodically obtained Figs. 36, 46, 56 (not shown). This pulse sequence is compared with a reference voltage related in phase with the detector rotation and a voltage representing the displacement is obtained, this being amplified and transmitted to motor 6 to restore the detector. If a mark is not detected at all after the detector has been arranged to track across the web along the spindles, the web can be stopped immediately, or an opticator acoustic signal be sounded. The arrangement can be adapted so that the whole web moves to line up the mark with the detector. A cutting tool may be operated by signals from a control circuit, to cut the fabric along the mark, and is arranged to be inoperative in the absence of these signals.
