Title: Improvements in or relating to processes for the polymerization of 3,3-disubstitutedoxetane
IPC: C08G65/18
Filed: 1957-08-22
Abstract: 3,3-Disubstituted oxetanes are polymerized in presence of catalyst comprising aluminium alkoxides of the general formula Al(X)(Y)(Z) wherein X is an alkoxy group and Y and Z are alkyl, halogen or alkoxy, the hydrocarbon portion of the molecule being straight, branched, alicyclic, aromatic or substituted as in the formula Al(RS)2X where S may be halogen or alkoxy. Specified catalysts are aluminium methoxide, ethoxide, isopropoxide, butoxide, and diethoxy chloride, and diethyl or di-isobutyl aluminium pentaerythritol trichloride. Polymerization temperatures range from - 20 DEG  to 300 DEG  C., and reaction may be in open or closed vessels or in situ on a surface, e.g. a wire to be covered.  Anhydrous and anaerobic conditions are preferred.  Diluents, e.g. heptane, decane, dodecane, carbon tetrachloride, tetrachloroethane or trifluoro-1,1,2-tribromoethane may be added.  All the examples relate to polymerization of 3,3-bis-(chloromethyl) oxetane. Other di-substituted oxetanes are mentioned and it is said that di-substituted oxetanes may be copolymerized together or with oxetane or other substituted oxetanes.  Example 3 describes the use of 2,21-methylene-bis-(4-methyl-6-tert.-butylphenol) as a stabilizing antioxidant.

[Class 97 (ii)] A section of a road or the like is plotted by determining the distance from the surface of the road to the mean point of a number of points distributed over a length of the road as this length is displaced along the road. In the form shown in Fig. 2, an even number of rods a with rollers b at each end are connected twoby-two by larger rods c pivoted to the middle points of adjacent rods a. The rods c are similarly connected in pairs by rods d which are similarly connected in turn by a rod e so that the middle point m of the rod.e is substantially on a vertical line through, and at a uniform height above, the mean point R of the section of road surface between the outermost rollers b. The point m is connected by a parallelogram linkage p, Fig. 6, to a frame k supported by four wheels r. A roller n pivoted in the ends of arms s, which are pivoted at the other ends to the frame k, bears on the surface of the road vertically beneath the point m. A cable l fixed at one end to the spindle of the roller n passes over pulleys o<1>, o<2> to a counterweight q and carries a pen t in contact with a chart driven by chains v from the roller n. The pen t traces a vertical section of the road with reference to the locus of the mean point. The recording apparatus may be mounted on the bar e instead of on the frame k. In a modification, the oscillating rods may be replaced by an equivalent system of cables and pulleys.

Abstract: 951,810. Moulding hollow plastics articles. IMPERIAL CHEMICAL INDUSTRIES Ltd. July 4, 1962 [July 28, 1961], No. 27437/61. Heading B5A. Hollow plastics articles, e.g. tubes, washing machine tubs, &c., are made by compressing particulate material, in a mould, at a first pressure sufficient to consolidate it, heating the material to render it viscous and then shaping the viscous material in said mould by applying a second pressure greater than the first pressure and subsequently solidifying the material in the mould whilst still under said second pressure. Thermosetting materials such as urea or melamine formaldehyde are solidified by further heating the mould above the curing temperature. Tubes are formed from resin impregnated asbestos flock by first compressing and heating the flock 6 in a cylinder 1,4 by a piston 2 (see Fig. 2). The now consolidated viscous material is further compressed by the core 3 so that piston 2 moves back, thus forming the material 7 to a tube shape (see Fig. 3). By varying the shape of the piston and core and the length of travel of the core various shaped open and closed tubes may be made as in Figs. 4-6 (not shown). The material is subsequently cured by heating whilst maintaining the moulding pressure. In a modification, the mould parts are mounted between the platens 14, 15 of a press, as shown in Fig. 7, movement of the cylinder being prevented, during the primary compression and heating, by the stops 16 and 17. The stops are removed prior to the secondary compression so that the cylinder moves downward, the lower limit of its travel being determined by stops mounted on the lower platen (see Fig. 8, not shown).

Abstract: 829,427. Nuclear reactors. UNITED STATES ATOMIC ENERGY COMMISSION. Sept. 10, 1956 [Dec. 14, 1955], No. 27585/56. Class 39(4). Apparatus for detecting the approach to prompt criticality of a nuclear reactor comprises means for periodically varying the reactivity at a period large compared to the period of prompt neutrons but small compared to the period of delayed neutrons, means for detecting the reactivity in the form of an electrical signal, and means for amplifying and comparing the A.C. and D.C. components of the electrical signals. In Fig. 1 a control rod 105 is moved in and out of the reactor 101 at a frequency between 10 and 100 cycles per second, and the reactivity of the reactor is measured by a neutron flux detector 103, the output of which is fed to a detector stage 106. Part of the output of the detector stage 106 is fed to a filter 107 tuned to the frequency of oscillation of the rod 105 and thence to an amplifier 108 and comparator 110, whilst the rest of the output is fed through an amplifier 109 to the comparator 110. The output of the comparator is connected to an indicating instrument 111, and it is explained in the Specification that this output is proportional to 1/1-kp where kp is the multiplication   factor for prompt neutrons. The output of the comparator is also used to shut down the reactor rapidly by means of a control rod 116 if k p  exceeds a preset value. A manually operated control rod 114 is provided for the use of the operator. In an alternative arrangement, Fig. 2 (not shown), the indicating instrument 111 is replaced by a servo-system which operates a control rod in the reactor.

Abstract: 1357328 Laminated panel COX & WRIGHT Ltd 8 June 1971 [8 June 1970] 27678/70 Heading B5N A decorative tile or panel is made by uniting a face layer of flexible sheet material 14, and intermediate layer 13 and a back layer 12 by a cut/weld press operation in which an upper platen 16 carrying a bevel edge cutting knife 17 is employed wherein the edges of the layers 12, 14 are welded by high frequency electrical heating and in the same stroke of the press the edges of the panel are trimmed. The face layer may be embossed during pressing or it may be flocked, printed or grained. The face layer may be formed of polymers or copolymers of vinyl halides, vinyl esters, or vinylidene halides; polyvinyl acetals; polymers and copolymers of acrylonitrile; polymers and copolymers of acrylic and methacrylic monomers; polyamides; polyurethanes based on polyethers or polyesters; cellulose derivatives; polyethers; polyethylene; polypropylene; and polymers or copolymers of chloroprene, the films being oriented or unoriented and suitably plasticized if required. The face layer may also be of a textile material of woven, non-woven or knitted construction. The material of the base layer may be chosen from any of the materials employed for the face layer but need not be decorative. The intermediate layer 13 suitably consists of foam or cellular plastics material. In a preferred embodiment during the cut/weld operation the cutting knife 17 sinks into the material for a predetermined period of time without reaching the final cutting depth, the knife 17 remains at the same depth during a cooling period in which the high frequency heating is switched off and finally when the weld has hardened the cutting stroke is completed to trim the panel. Before welding two or more of the layers may be temporarily tacked together by means of an adhesive. The regions of the panel to be welded may have an adhesive coated on to them or applied as a separate film prior to welding in order to enable the welding to be effected. The panel may have a coating of pressure-sensitive adhesive applied to the outer face of the back layer, said adhesive being protected by release paper.
