IPC: C08G8/00
Filed: 1949-05-30
Abstract: Aromatic polyphosphate polymers wherein the repeating unit is <FORM:0679834/IV (a)/1> are prepared by condensing an aryloxyphosphoryl dichloride of formula POCl2(OR1), where R1 is a diphenyl or substituted diphenyl radical, with a dihydroxy aromatic compound of formula R11(OH)2, both hydroxy groups of which are nuclear and attached to non-adjacent carbon atoms, R11 being a radical having at least one aromatic nucleus.  Specified phosphoryl dichlorides are ortho- and para-phenylphenoxy-phosphoryl dichlorides (see Group IV (b)). Specified dihydroxy compounds are hydroquinone, resorcinol, chlorinated hydroquinone, 4 : 41-dihydroxy-diphenyl, 4 : 41-chlorinated dihydroxy-diphenyl, 4 : 41-dihydroxydibenzyl, and 4 : 41-dihydroxy-diphenyl ether.  The polymers are soluble in chloroform, dioxane, benzene, toluene and mixtures of benzene and alcohol.  They may be used as coatings or adhesives for metals, glass, wood or rubber and for making gramophone records.  The reaction may be carried out in an inert atmosphere, e.g. nitrogen or carbon dioxide, in presence of a hydrogen chloride elimination catalyst, e.g. tin, and preferably suction is applied towards the end of the reaction to remove hydrogen chloride.  Condensation may also be effected in a common solvent, e.g. ether, benzene or chloroform in presence of a hydrogen chloride acceptor, e.g. pyridine.  In examples: (1) para-phenyl-phenoxy-phosphoryl dichloride and hydroquinone are heated whilst excluding water and absorbing evolved hydrogen chloride. Purification is effected by dissolving the crude resin in benzene and precipitating with ether; (2) ortho-phenyl-phenoxy-phosphoryl dichloride and hydroquinone are heated first alone and then in presence of tin; (3) para-phenyl-phenoxy - phosphoryl chloride and 4 : 41-dihydroxy-diphenyl ether are reacted as in (2). Specifications 524,510 and 644,468 are referred to.ALSO:Para- and ortho-phenyl-phenoxy-phosphoryl dichlorides are prepared by treating para-phenyl phenol, or ortho-phenyl-phenol, at raised temperatures with more than one molar proportion of phosphorus oxychloride, preferably in presence of calcium chloride or iron.  The products are condensed with aromatic dihydroxy compounds to produce resins (see Group IV (a)). Specification 524,510 is referred to.

Patent GB-711429-A (GB)
Title: Improvements in apparatus and methods for uniting layers of thermoplastic material
IPC: B29C65/14
Filed: 1951-06-21
Abstract: 711,429. Seaming non-metallic sheets. PACKS. PTY., Ltd. June 21. 1951 [June 27, 1950], No. 14768/51. Class 42 (1) A method of uniting layers of thermoplastic material comprises holding at least two restricted area portions thereof lapped in mutual contact while leaving an outer surface of the lapped portions uncovered, maintaining the parts of the layers beyond the said portions below the fusing temperature of the material of the layers, and exposing the said uncovered surface to a heat radiating element, thereby to fuse the portions, without mechanical contact between them and the said element. As shown in Figs. 2 and 5 the layers 19 may be held between a stationary member 13 having a cavity 15 which contains a heat radiator element 16 such as an electrical resistor wire, and opens as a slot in the upper surface of the member 13, and a member 17, mounted on arms 22 which are mounted on a rod 23 pivoted in brackets 24 on the base plate 14, and biased upwardly by a spring 26 acting on an arm 25. The member 13 may be cooled, as by circulation of liquid through a pipe 21, or by blowing air on to it. A latch 30. acting on a lug 28 is provided to hold the member 17 in lowered position, and is connected by a link 33 to the armature 34 of a solenoid 35, by actuation of which it may be released. Lowering of the member 17 operates the arm 37 of a switch' 36 ; closure of the switch 36 allows current to flow through the heater 16, and puts into operation an electronic circuit, which, after a time delay, allows current to flow through the solenoid 35, releasing the latch 30 and thus permitting the member 17 to rise, the switch 36 then reopening. In alternative constructions the anvil member may be unslotted, and the heat radiator may be included in a groove in the holding member; both members may be straight, or they may be rollers or pulleys between which the layers are passed, or the holding member may be rolled over the stationarily-held layers. The cavity in the-holding member may straddle a projecting tongue on the anvil, which may be mounted cantilever fashion. Or, the layers may be held by hand or by clamps across a support and a heating member brought closely adjacent to. the portions lying thereover, without contacting the same, or the heater may be included in a cavity in the support; or both methods of heating may be used. In a further modification (Fig. 11), the layers 64, to be joined, are passed between a belt 60, driven by a pulley 59, and a pulley 61, consisting of two spaced cheek discs, forming between them a groove. A heating element is mounted on a stationary carrier between the discs. Two or more closely spaced seam lines may be made during a single operation, e.g. by providing the holding member 13, Fig. 5, with two slots 15, each furnished with a heating element 16 ; the member 17 may then be provided with two tongues such as 18.

Abstract: 746,008. Sewing-machines. SINGER MANUFACTURING CO. May 20, 1954 [June 1, 1953], No. 14800/54. Class 112. [Also in Groups XXVI and XXXIV] Lubricating.-The bed-shaft 12 is mounted in bearings 13 . . . 16 and provided at one end with an axial bore 42, and lubricant is delivered to this end and fed along the bore as the shaft 12 rotates, by means of a helical spring 49, and thence through radial holes 43, 44, 45 to bearings 46, 47, 48. The shaft 12 is formed with a crank 19 for actuating a connecting rod 20 which is provided with a lubricant splasher 21 dipping into lubricant in a sump 22. As the shaft 12 rotates, the splasher distributes lubricant within the standard 11. Some lubricant collects in a trough 23 and flows into a fitting 24 which supplies a main tube 25 for distribution to tubes 29, 30, 31 leading to bearings. The tube 30 at one end is provided with a wick which extends into a fitting secured to the bearing 16 and supplies lubricant through an opening in a bushing 33 surrounding the end of the shaft 12. One end of the bushing is closed by a cap 40, and a chamber 41 is formed between the end of the cap and the end of the shaft 12, the chamber being partly filled by a wick 50 which is coiled around the spring 49. The spring is fixed at one end to the cap 40. As the shaft rotates the spring 49 acts as a screw pump to force the lubricant along the bore 42. A helical groove 56 is formed on the outer surface of the shaft 12 to prevent escape of lubricant along the inner surface of the bushing 33.
