Title: Improvements in or relating to closure means for vessels
IPC: B65D45/02
Filed: 1921-07-20
Abstract: 187,338. Hole, S. July 20, 1921. Closures completed by outstanding p a ck i n g rings; retaining-devices in receptacle neck above closure.-The lower edge of the lid of a milk churn or other vessel is formed with means for making a fluid-tight joint. Circumferential grooves C<2>, C<3>, Fig. 1, are formed on the lid, the higher one being adapted to register with a similar groove B<1> on the flared mouth of the can when the lid is closed. Above and below the groove B<1> are lips or projections B<2>, B<3> respectively. A ring D of elastic material such as rubber and preferably of circular section is placed in the lower groove C<3>, and on applying pressure to force down the lid the ring rolls over the body projection B<2> and becomes transferred to the upper lid groove C<2>, Fig. 2, lying compressed between that and the groove B<1> on the body. Recesses E<1> are provided in the flanged edge of the lid, through which recesses short levers can be inserted to prise up the lid when required to open the vessel. The invention may be applied to a lid adapted to fit outside the body, which would then be provided with the two grooves, the lid having a single groove. The lid may have additional securing means comprising spring catches H arranged behind the recesses E<1> and adapted to engage under an internal lip G formed at the mouth of the body. The spring catches can be pressed back by means of the levers introduced into the recesses E<1> to prise open the lid.

Title: The production of coatings of synthetic resin by electrostatic spraying
IPC: D06M10/08
Filed: 1960-06-03
Abstract: 956,564. Coating surfaces ; coated fabrics. POLYCHEM A.G. June 3, 1960 [June 3,1959], No. 19837/60. Headings B2B and B2E. [Also in Division D1] In a method of producing coatings of synthetic resins in which a composition of the resin is exposed to an electrostatic high tension field by means of which particles of the composition are separated and are transported to and deposited on a receiving surface, a small quantity of at least one compatible polar organic compound is incorporated in the composition to increase the electrical conductivity thereof. Examples are given of coating strips of paper and aluminium foil; the substrate may also be of textile or synthetic material. The coating material may be paraffin wax, polyethylene, or mixtures thereof; polyvinyl chloride ; or a ketone resin, plus plasticizers and solvents; the polar substance may be a salt, ester, or amide of a long chain organic acid of which numerous examples are given. A plurality of coats of the same or different compositions may be applied. Instead of a continuous strip the carrier to be coated may be a drum. The coating may afterwards be separated from the carrier as a self supporting film suitable for use as packing material or as a diaphragm. When the substrate is of insulating material a counter electrode may be arranged behind it. Coating apparatus. As shown, apparatus for coating a continuous web in transit from one spool to another spool 2 comprises a nozzle 10 fed by gravity from a tank 7 which may be heated by heaters 8, the nozzle being connected to one side of a high voltage supply 11. The other side of the high voltage supply and the strip 3 are earthed. The strip may be heated simultaneously with the coating process by radiant heaters 6. A counter electrode 12 may be employed comprising a band of foil; if this band is provided with cut-outs or other shapes the carrier strip will be provided with a correspondingly patterned coating when it is moved synchronously with the counter strip. Pressure additional to that provided by gravity may be applied to the coating material if desired.

Title: Improvements in and relating to pumps, especially priming pumps, of the liquid ring type
IPC: F04C28/06
Filed: 1956-06-27
Abstract: 810,845. Centrifugal pumps. GILKES & GORDON Ltd., G., and CLARKE, B. E. June 27, 1957 [June 27, 1956], No. 19909/56. Class 110 (1). In a liquid-ring pump in which the impeller is enclosed by a ported casing containing the working liquid, the casing can rotate freely to afford an idle condition, means being provided for retarding or stopping the rotation to afford a pumping action. A reservoir 22, Fig. 1, containing a filter 23, is provided at the discharge side of a centrifugal pump 24 so that it is filled automatically when the centrifugal pump is operating. When the centrifugal pump is idle, water from the reservoir 22 descends through a pipe 25 and passes through a valve seat 36 and a passage 29, Figs. 1 and 2, to the interior of the outer casing 1 of a liquid-ring priming pump. The water now filling the outer casing 1 cooperates with vanes 21 on the outside of a rotary inner casing 8 to retard the free rotation of the inner casing about the impeller shaft 4, so that the liquid-ring pump becomes effective to draw air from the suction of the centrifugal pump 24 through a pipe 35. The air passes through a passage 19 to a bore 17 of the shaft 4 and enters suction port or ports 12 of the inner casing 8 through radial holes 16. Delivery port or ports 11 discharge the compressed air into the outer casing 1. The air escapes downwardly through a discharge pipe 39 to a drain 31. Pipe 39 also acts as a water overflow. When the centrifugal pump 24 is fully primed, the delivery pressure acts on the underside of a piston 33 to raise it against the action of a spring 38. In its raised position, the piston rod 32 obturates the passage 19 to close the connection to the centrifugal pump suction, and a valve 28 is lifted from a seat 37 and closes the seat 36 to shut off the supply of water from the reservoir 22. The water in the outer casing 1 now drains through a passage 30 and the open seat 37 to the drain 31. The inner casing 8 is now free to revolve in air at nearly the same speed as the impeller 5, so that the liquid-ring pump idles. Water leaking past the piston 33 may be supplied through passages 43, 44 to bearing 3 for lubrication purposes. The control may be manual instead of automatic and may comprise a brake applied to the inner casing 8. Instead of being journalled on the shaft 4, the inner casing 8 may be mounted on reparate bearings. Specification 370,585 is seferred to.

Title: Method for the preparation of 4-hydroxy quinoline compounds
Filed: 1946-07-05
Abstract: 4-Hydroxyquinoline compounds are prepared by heating a substituted acrylate or the isomeric anil having the respective formula <FORM:0626472/IV (b)/1> wherein Y represents hydrogen or one or more monovalent nuclear substituents and R represents an alkyl radical, the temperature being sufficient to effect ring closure while the acrylate or anil is in solution in at least ten times its weight of an inert solvent having a boiling point of at least 200 DEG  C., e.g. in solution of at least twenty times its weight of said solvent.  The alcohol formed during the cyclisation may be permitted to distil from the reaction mixture, and heating is continued until the separation of the alcohol substantially ceases.  Y may represent hydrogen, or chloro, bromo, iodo, fluoro, dialkyl-amino, hydroxy, alkyl, e.g. methyl or ethyl, haloalkyl, carbalkoxy, e.g. carbethoxy, or alkoxy, methoxy or ethoxy radicals.  The process is particularly useful for the preparation of 7-substituted-4-hydroxyquinolines.  In an example, the substituted acrylic acid ester or its corresponding aril obtained by condensing m-chloroaniline with the methyl ester of formylacetic acid, is heated in diphenyl ether or a mixture of diphenyl ether and diphenyl to yield 4-hydroxy-7-chloroquinoline.  Substituted acrylic acid esters or their corresponding arils of the respective general formula <FORM:0626472/IV (b)/2> wherein R and Y have the above significance, are prepared by condensing aniline or a nuclear substituted aniline with a formylacetic acid ester.
