Title: Improvements in oil stoves
IPC: F24C5/18
Filed: 1935-12-02
Abstract: 466,585. Wick burners, SNELL, C. SCOTT-, and C.S.S., Ltd. Dec. 2, 1935, No. 33356. [Class 75 (i)] In an oil stove comprising a chimney less wick burner or burners to which air is supplied under pressure, oil is supplied to the wick burners from a reservoir situated at a lower level by means operative only so long as the air supply is maintained. Fig. 1 shows a stove comprising wick burners 2 supplied through a trunk 1 with air by a fan 3 driven by an electric or other motor 4. A centrifugal pump 16 also driven bv the motor 4 delivers oil in excess of requirements from a reservoir 5 through a pipe 12 to chambers 13 arranged inside the burners and communicating with the wick chambers 6. The excess oil overflows from the chambers 13 into a central chamber 7 from which it is returned by a pipe or pipes 14 to the reservoir. When the motor stops, the oil in the chambers 6, 13 drains back to the reservoir 5 through the pump 16 or a small leakage connection. The air entering the chambers 7 from the trunk 1 is regulable by means of rotatable apertured tubes 10 and is directed on to the flame by baffles 8. Instead of the centrifugal pump 16 an Archimedean screw or endless band elevator may raise the oil to the burner level.. Fig. 3 shows a modified burner construction in which the air is conveyed through a tube 46 to the space between a centring disc 17 and the baffle 8. Some air is also delivered to the chamber 7 through an aperture 18. Air may alternatively be supplied to the burner by a steam injector as described in Specification 431,849, and the oil pump may be operated by clockwork. A lever operated by an aneroid chamber traversed or heated by the steam opens a valve in the oil supply pipe, disengages a stop in the clockwork, and closes a burner drain pipe. Specification 454,304 also is referred to.

Title: Improvements in or relating to the manufacture of rubber compositions
IPC: C08L89/06
Filed: 1932-08-13
Abstract: Flocculent rubber precipitates of the "protected" type are admixed with granular, fibrous or divided materials, the amount of precipitate and the quantity of water being adjusted so that the product is of a crumb-like character.  The wet crumb may be converted into a substantially dry form as by drying under agitation. Flocculent rubber precipitates of the "protected" type are precipitates having a sufficiently hydrated layer to prevent the formation of a consolidated product on filtration. Precipitates containing aluminium silicate produced in situ are, however, excluded.  Such precipitates include those containing magnesium silicate produced in situ, or precipitates produced by the addition of zinc sulphate and magnesium sulphate to dilute rubber latices, provided that in each case a relatively large proportion of protective colloid is added.  The granular &c., materials include leather fibre, wood flour, cork dust, jute fibre, cotton flock, naturally short cellulose fibres and ground fibres.  Softening and adhesive agents may be incorporated, and the compositions may be rolled into sheets with, if desired, a fabric backing.  Colour effects may be produced by using differently coloured crumbs or by painting the surface with, e.g., cellulose colours.  Specifications 219,635, 290,313, [both in Class 70, Indiarubber &c.], 373,222, 373,263, and 396,159 are referred to.  The Provisional Specification describes also coagulation of the initial rubber latex with acids such as acetic acid; the use of coagulation restraining agents such as caustic potash, casein, sodium aluminate, glue and gum acacia; and gives an example of the use of a rubber precipitate containing aluminium silicate produced in situ in admixture with a mineral oil precipitate, cork dust, lithopone and iron oxide.
