Title: Improvements in or relating to chlorinated polythene compositions
IPC: C08K3/22
Filed: 1947-07-25
Abstract: A chlorinated polythene composition adapted, upon heating, to be converted to a less soluble and fusible form, comprises soluble chlorinated polythene, a lead oxide, and an aromatic per-acid, an ester thereof or an aromatic peroxide.  By "soluble" is meant soluble in boiling trichlorethylene.  The compositions are preferably produced by mixing the ingredients at a temperature below the decomposition temperature of the peroxy compound and then heating above this temperature until at least 55 per cent of the chlorinated polythene is insoluble.  The mixing may be done on heated rollers with or without solvents and the final heat-treatment completed in a mould or a press or at ordinary pressures in an oven.  Alternatively, the chlorinated polythene may be mixed with the lead oxide and extruded on a wire which is then immersed in a solution of the peroxy compound in a medium which swells but does not dissolve the polymer. The solvent is then evaporated and the wire heated above the decomposition temperature of the peroxy compound.  Any lead oxide, e.g. litharge, red lead or lead dioxide, may be used, preferably in amounts of 1-60 per cent by weight of the chlorinated polythene. Suitable peroxy compounds are tert. butyl perbenzoate, di(tert. butyl) diperphthalate, isopropyl perbenzoate, diethyl diperphthalate, benzyl perbenzoate, lauryl perbenzoate, monoperphthalic acid, perbenzoic acid, benzoyl peroxide and phthalic acid peroxide.  The amounts normally used are from 1-5 per cent by weight of the polymer. Before the heat-treatment, there may be mixed with the compositions small proportions of lubricants, e.g. microcrystalline hydrocarbon wax and paraffin wax, plasticizers, fillers, pigments, stabilizers and natural and synthetic resins.  The heat-treated compositions may be used in the form of sheets, films, filaments, coatings and moulded, impregnated and laminated structures for the manufacture of a variety of articles.  Specifications 471,590 and 481,515 are referred to.

Wedge-shaped articles 2 from a furnace are carried by trolley 1 which is fed sideways and horizontally into the position shown in Fig. 1 (plan), and piston 9 is operated to push the line of six articles shown towards the right on to slideway 5. The slideway is curved as shown so that each article which is standing on its end is moved into a horizontal position so as to rest on its wedge side and is then further orientated by dropping over step 12 on to conveyer 11 which conveys it base-downwards to turntable 14 which turns on a vertical axis. Alternate articles are thus displaced through 180 degrees so that they arrive on packing table 15 compactly positioned and are further displaced by pusher 16 on to pallet 17. Guide 6 pivoted at 7 ensures alignment for the six articles. At 13 a man inspects the articles and ejects imperfect ones by means of an hydraulic cylinder.

[Also in Division F1] A fluid joint between two adjacent coaxial surfaces comprises a deformable resilient sealing ring making sealing contact with both surfaces and formed with an annular groove in which is engaged an annular projection on one of the members, the axial height of the groove in the unstressed condition of the ring being less than the axial height of the projection. In the embodiment disclosed, a lid 13 of a pressure vessel 10 (see Division F1) fits within the pressure vessel and has an annular projection 34 engaging a groove in a sealing ring 30. Since the height 42 (Fig. 3, not shown) of the projection is greater than that of the groove in the unstressed condition of the sealing ring, the ring becomes deformed (Fig. 3, not shown) on entry of the projection. Thus the sealing ring is pressed firmly against the container 10 to form a firm seal when the lid is held inside the container. A joint between a tube 23 and a curved surface 10 is shown in the lower half of Fig. 1, but not described in detail.

(Specific examples given.) The mol. fraction of the element or compound of Group V-B may be 0.05 to 0.50 and that of the compound of Group III-B may be 0.01 to 0.15, but preferably less than the mol. fraction of the Group V-B element. The temperature of the reaction may be 400-1500 DEG  C. Either the Group III-B compound or the Group V-B compound or element may be doped to give specific conductivity types.  The substrate may be formed of (a) a compound from elements of Groups III-B and V-B, (b) a compound from elements of Groups II and VI, (c) a compound from elements of Groups I and VII or (d) Si, Ge or a metallic conductor. All the binary AIII-BV compounds are specifically referred to, and GaAs, GaP, InP, AlAs, AlSb and InAs are prepared in the examples.

In the system described both driving and non- driving wheels are provided with pulse generators whose outputs pass through shaping circuits 21-24 to up/down counters 25, 26. Each counter accepts the output from a driving and non-driving wheel such that when " no slip " occurs the counter remains at zero. When slip occurs the number of positive pulses counted in a given time exceeds the number of negative ones and when a threshold count is reached, OR gate 27 transmits an output pulse to multivibrator 28. Under normal conditions contact breaker 31 directly controls ignition circuit 10 through circuits 32 and 38. The output from multivibrator 28 disables this connection and causes the ignition signal to pass through a delay circuit consisting of monostable multivibrators 34, 35, gate circuit 36 and bi-stable multivibrator which retards the engine ignition by a fixed amount.
