Abstract: 551,076. Honing or lapping piston rings. WELLWORTHY PISTON RINGS, Ltd., and HOWLETT, J. W. Feb. 16, 1942, No. 2028. [Class 60] [Also in Group XXVI] In the surface finishing of piston rings, other than those formed by bending a length of wire the rings 11 are honed or lapped in a direction which is not parallel to the axis of the rings and is not in a plane at right angles thereto, either the honing stone or the lapping block being spring-pressed towards the ring periphery, or the ring being left resiliently free whereby the periphery, even when not cylindrical, presents a cross-hatched finish. A number of rings 11, Fig. 2, are mounted between end plates 12 on a mandrel supported between centres 13 and are slowly rotated while being treated by a spring- pressed lapping block 14 carried on a reciprocating slide 16. The rings may be closed to their own normal working dimension against steel inserts carried by the mandrel. A jig 17, Fig. 3, having a number of holes 18 for a lapping block 14 spring pressed at 19 may be provided, the jig being chamfered at 21 to facilitate entry of the group of rings when mounted on a mandrel. In operation the mandrel is rotated and either the mandrel or the jig is reciprocated. In a modification the blocks 14 define a cylindrical surface corresponding to the work surface of the rings and are fast in the jig 17 the rings being left resiliently free during lapping. Specification 488,687, [Group XXVI], is referred to.

Title: Improvements in and connected with the production of sound metal castings
IPC: B22D27/06
Filed: 1944-02-05
Abstract: 574,598. Thermo-aluminic mixtures. UDY, M. J. Feb. 5, 1944, No. 2168. Convention date, May 10, 1943. [Class 82 (i)] [Also in Group XXII] Piping is prevented by covering the metal with slag having lower fluidity than, and a higher temperature than the melting point of, said metal. This may be done by introducing into the hot top, gates and risers, after pouring, an exothermic reaction. mixture which will produce an iron oxide-bearing slag. A suitable mixture is sodium nitrate 25 parts by weight, ferro-silicon (75 per cent silicon) 25 parts, mill scale 70 parts, and charcoal 0.5 parts, ground in a ball mill to pass 95 per cent through a screen 100-mesh to the inch and mixed with 15 parts of coke which will pass a 4-mesh screen but be retained by a 20-mesh. The charcoal ensures rapid ignition and the coke reduces fluidity and absorbs heat, thus producing slag at about 2900‹ F. Sodium chlorate may be used instead of the nitrate, silicon, magnesium, calcium or aluminium instead of the ferro-silicon, and crushed electrode carbon or quartz instead of the coke.

Title: Improvements in or relating to apparatus for the bulk polymerisation of polymerisable compounds
IPC: C08F2/02
Filed: 1957-01-23
Abstract: <PICT:0852289/IV(a)/1> Vinyl chloride is continuously polymerised in the liquid phase by means of gamma rays in a process in which after separation of the polymer and unreacted monomer by filtration, the unreacted monomer is returned to the reactor.  In the illustrated apparatus, the monomer is stored as a liquid under pressure in reservoir 1 and passed to a tank 3 (where it joins the recycle stream) from which it is withdrawn via a compressor 4 and preheater 7 into the reactor 8.  The latter has a retractable source of gamma rays in a sheath 9 and an agitator in the form of a grid 13 controlled by rods 13a and 13b.  After reaction the mixture is passed to one of filters 17 and 18 and the monomer returned via line 23 and reservoir 25 to tank 3, if desired after a second filtration.  The polymer is discharged from the bottom of the filters after removal of monomer as vapour by means of pump 26 assisted by heating (by means of jackets 21,22) and agitation of the polymer by means of agitators 19.ALSO:<PICT:0852289/III/1> An apparatus for the continuous bulk polymerization of a monomer, the polymer of which is insoluble in the monomer, comprises a reactor, at least two filtering devices which may be alternatively placed in communication with said reactor for separating the polymer and monomer, and means to return the separated monomer to the reactor.  In the accompanying Figure, the monomer is passed from reservoir 1 into a tank 3 and thence after compression and preheating into reactor 8.  In the reactor polymerization proceeds under the influence of a retractable source of gamma rays in a sheath 9 and is assisted by agitation with a grid 13 controlled by rods 13a and 13b.  The product mixture passes via line 16 to one of the filters 17 or 18 where unreacted monomer is removed, recompressed and passed to reservoir 25: the monomer may alternatively if necessary be refiltered by passing through line 27.  The filtered monomer is returned to tank 3.  When the filter has reached capacity, the product mixture is diverted to the second filter, and the monomer remaining in the first filter (say 17) is removed as a vapour by pump 26: evaporation of the monomer is assisted by passing a hot fluid through jacket 21 and agitating the polymer by agitator 19.  Polymer is then discharged through the bottom of the filter.
