Patent GB-889103-A (GB)
Title: Modified polyvinyl acetate powders and compositions
IPC: C08J3/12
Filed: 1960-09-22
Abstract: A process is described for making a polyvinyl acetate copolymer powder.  Vinyl acetate is emulsion polymerized with monomer(s) containing an acid group such as crotonic acid, maleic anhydride, itaconic acid, acrylic acid and methacrylic acid by the usual methods for polymerizing vinyl acetate.  If more than 10% of acid monomer is required in the polymer, the polymerization is preferably carried out in solution.  The degree of polymerization is preferably higher than 1,000.  Before drying the emulsion is mixed with an ammonium salt of a weak acid such as ammonium carbonate, acetate, oxalate, tartrate or benzoate, and an oxide and/or hydroxide of a polyvalent metal such as calcium or zinc. The mixture is then spray dried in a hot or warm stream of air. The powder can then be mixed with fillers and pigments which do not affect the alkalinity in the emulsion because the dispersability of the powder is critically dependent on the alkalinity.  Titanium oxide, mica, kaolin or talc can be used. Plasticizers such as tricresyl and tributyl phosphate can be used. Other paint additives such as carboxymethyl cellulose, methyl cellulose and urea-formaldehyde prepolycondensate powder can be added.  Examples are given showing how the process is carried out. Specification 753,173 is referred to.

Title: Fuel oil supply arrangement
IPC: F16K23/00
Filed: 1971-11-25
Abstract: 1379892 Valves C A BJORKLUND 25 Nov 1971 [7 Dec 1970 17 March 1971] 32827/74 Divided out of 1378863 Heading F2V [Also in Division F4] In a fuel oil supply arrangement comprising a cut-off valve in a line between a burner and a pump, the valve comprises a resilient element which is deformed by oil pressure in operation but relaxes, upon pressure drop due to pump shut down, to increase the volume of a chamber and reduce the pressure therein, thereby effecting suck-back of oil from the burner line. In the embodiment of Fig. 2 a rubber piston 66 is forced upwardly by the pressure of oil entering through line 62 to permit the oil to pass to burner line 64, the upward movement of the piston deforming the latter to fill the space 69 whereby, on pump shut-down, the space 69 is redefined to effect suck-back via passage 63. Another valve, Fig. 4, having an inlet 121, outlet 122 and return 123, comprises a diaphragm 125 and a split rubber body 129 which are moved by oil pressure into positions in which a hole 126 in the diaphragm is adjacent and aligned with passage 127 and the parts of the split body are deformed to remove the frustoconical suck-back space thereabove and are separated to allow oil flow to the outlet. Figs. 6 and 7 (not shown), illustrate a valve having a flexible diaphragm (173) with a central aperture (174). When the pump is stopped the diaphragm is turned inside out resulting in closure of the aperture and suck-back at the outlet. Fig. 10 shows a device which can be arranged between the cut-off valve and the burner to permit oil pressure build up whilst the burner's fans are reaching full speed, and comprises a valve 168 which closes return line 164 when the pump is operative, thereby causing diaphragms 166 to be forced against walls of chamber 165. Alternatively, the flexible diaphragm of the valve of Figs. 6 and 7 is connected downstream of a flexible sleeve valve (186), Figs. 8 and 9 (not shown). When the pump is operated flow to the outlet is established through the diaphragm and the sleeve valve closes a return passage (188) and causes oil to be stored in a rubber bladder (191). In Fig. 11 (not shown), a diaphragm (244) centrally supports a tapered member (245) having a bore (249) therethrough closed at its downstream end by a flexible sleeve (247) mounted on the member (245). When the pump is operated the diaphragm is deflected until the member (245) abuts against a seating whereby the volume of the chamber at the downstream side of the diaphragm is reduced. Thereafter the sleeve (247) is lifted away from the member (245) to establish flow through the bore (249) to the valve outlet. In another valve, Fig. 12, a hollow rubber ring 259 perforated at 263 is expanded by the oil pressure to eliminate the peripheral groove shown and thereby prevent flow to return 261, whereafter fuel forces its way past a rubber ring 256 to the outlet 252. Annular groove 260 provides the suck-back characteristic when the ring 259 contracts after pump shut down.
