IPC: F23D1/00
Filed: 1928-02-21
Abstract: 308,054. Prior, A. C. Feb. 21, 1928. Mixing fluids in flow.-Apparatus for mixing streams of fluid in flow, of the kind described .in Specification 203,794, comprises means for projecting a main stream in the form of a converging cone, a second stream in the form of a diverging cone emanating from within the main stream, and a third stream as a cone converging on the main stream, all three streams being given a rotary motion, and the supplies of both the central stream and the inner converging stream being adjustable; the apparatus may be used as a burner for firing a boiler. The main stream flows from a chamber C between converging surfaces 4, U, each provided with inclined vanes H, T to impart a rotary motion to the fluid, which may consist of pulverulent fuel in a stream of gas or air. The member U may be adjusted by means of a worm wheel X engaging screw threads P thereon. The second stream issues from a tube V in the end of which is a flared member 0 and inclined vanes S. The tube may be adjusted longitudinally by means of a rack 12, and the flared member 0 moved to vary the orifice by means of a hand-wheel K; the second stream may be air, and impinges on the first to deflect it outwards. The third stream issues from a channel Y past deflectors N, which may be fixed, or, as shown, be pivoted and simultaneously adjusted by means of connections 7 to a rim 9.

Abstract: 478,461. Hair - curling appliances. VOLKEL, E. Feb. 26, 1937, No. 5914. Convention date, Feb. 27, 1936. [Class 131] A hair-curling device comprises a winding rod provided with means for the temporary attachment of an extended elastic band or cord for binding the wound hair before the winding rod is removed, and a handle projecting beyond the position of the extended binder. As shown in Fig. 1, the curler is of scissors-like form and the elastic cord 2 is attached to one limb by means of a fixed hook 4 and a slidable hook 6 engaged by a loop and a hook on the elastic cord. One end of the strand of hair is gripped between the limbs of the curler and the strand is wound thereon. The elastic cord is detached from the hooks 4, 6 and its ends are hooked together to retain the curl, and the curler is then removed. In a modification, Fig. 2, the curler is of U-shape and the elastic band 2 is stretched between a slot 14 and a stud 16, the ends of the band being provided with a button 13 and a loop 15. An additional slot 14<1> is provided to receive the loop 15 for securing a wound curl. In a modified use of the curler shown in Fig. 2, a second elastic band 2a is stretched between a slot 19 and the stud 16, and the hair is wound between the open limbs 12, 18 in the form of several superimposed figure-of-eight coils, and the two bands are then joined together crosswise. The curler is withdrawn and the hair, retained by the bands, exhibits a wavy formation. In a further modification the U-shaped limbs are crossed and are normally pressed together by the resiliency of the device. In a modified elastic band a small celluloid tube is carried by the central part of the band to impart stiffness thereto.

[Also in Group XIII] A fire-detecting device comprises a protective housing 1 containing a microswitch 2 actuated by movement of a lever arm 3 attached to a pivot shaft 4 projecting through a housing wall 6, the operating movement being obtained from the differential expansion of a rod or bar 10 and a base member 11 of dissimilar material. Member 11 is a cast-iron bar bolted to an external web 19 of the housing 1 and screwed at 9 to one end of a brass bar 10, the other end of which is screwed at 8 to a lever arm 7 carried by the pivot shaft 4. Differential expansion of bar 10 and member 11 causes a rocking movement of arm 7, the movement being magnified and transmitted through the longer arm 3 to actuate the plunger 15 of the microswitch 2. The operating temperature is adjusted using an abutment screw 16 carried by the arm 3. The housing 1 has a front cover-plate 12 giving access to the microswitch and a side cover-plate 13 giving access to an extension 14 of the housing for terminal leads. In another embodiment (Figs. 3-5, not shown), the expansion bar 10 has a protective wire grill and the switch device is mounted in a further circular casing attached to a wall or ceiling.

Title: Organopolysiloxane compositions for rendering cellulosic materials non-adherent
IPC: D21H27/00
Filed: 1955-03-04
Abstract: A liquid composition for rendering cellulosic materials non-adherent consists of an aqueous emulsion of a liquid organo-polysiloxane containing at least 1 per cent by weight of aluminium hydroxide or aluminium silicate, based on the organopolysiloxane and a water-soluble salt of titanium, zirconium, tin, lead, zinc or nickel in a quantity which provides at least 0.1 per cent by weight of the metal constituent of said water-soluble salt, based on the weight of organopolysiloxane. The organopolysiloxanes include those of the general formula <FORM:0792845/IV (a)/1> where R is a monovalent hydrocarbon radical x is from 1 to 1.5, y from 0.75 to 1.25 and x+y from 2 to 2.25; those of general formula <FORM:0792845/IV (a)/2> where a is not less than 3, e.g. polysiloxanes of formula <FORM:0792845/IV (a)/3> Water-soluble metal salts specified are zirconium tetrachloride, zirconium sulphate, zirconium oxychloride, zirconium nitrate, zirconium acetate, zirconium ammonium carbonate, zirconium oxybromide, stannous chloride, zinc acetate, zinc nitrate, nickel sulphate, nickel acetate, nickel chloride, titanium oxychloride, titanium nitrate, titanium oxalate, stannous gluconate or organic or inorganic complexes thereof.  Dispersing or emulsifying agents, e.g. sulphonated condensation products of fatty acids with organic amines, sulphonated aromatic or alkyl aryl sulphonate derivatives and emulsion stabilizers, e.g. oleic acid may be added. In the examples: (1) a methyl polysiloxane was made by hydrolysing a mixture of trimethyl chlorosilane, methyl trichlorosilane, dimethyl dichlorosilane and mixed chloromethyl disilanes, the product being neutralized with sodium carbonate, filtered, stripped and mixed with water, oleic acid and an emulsifying agent to form a master emulsion which was mixed with water, sodium carboxy methyl cellulose, aqueous stannous gluconate and aluminium hydroxide to form a treating emulsion; (4) the master emulsion of Example (1) is mixed with stannous gluconate and an aluminium hydroxide gel; (7) as in Example (1) with the omission of the sodium carboxymethyl cellulose and the substitution of aluminium silicate for aluminium hydroxide.  The treating emulsion are used for coating cellulosic materials, e.g. kraft paper, glassine paper, parchment paper, linen rag paper, regenerated cellulose, sulphite cellulose paper or sheeting or box materials.

Abstract: 1,141,481. Making tube reducing rolls; electro erosion. INDUSTRIAL TOOL ENG. CO. 16 Feb., 1966 [13 Sept., 1965], No. 6858/66. Headings B3A and B3V. A roll such as 42 for reducing tubes has tapered grooves 32 formed thereon by electroerosion using tapered electrodes 81. Two similar rolls 42, 43 supported on rollers (47), Fig. 8 (not shown) and located axially by end stops (53), (54), Fig. 7 (not shown), have each three pre-formed grooves eroded simultaneously by parallel electrodes 81, Fig. 9 (not shown). The electrodes are each mounted between a lower pin 77 and an upper adjustable pin 76, the pins being supported on arms 75, 74 connected by columns 65, (66) to form a vertical movable carriage. This carriage is moved vertically by an hydraulic jack (60), Fig. 10 (not shown). A vertical rack 82 on arm 72 drives a pinion (85), Fig. 8 (not shown) meshing with gears (87), (88) on the rolls 43, 42 whereby the latter are rotated to correspond with the movement of the electrodes. The gears (87), (88) are removably secured to the rolls by split clamping rings (90), Fig. 12 (not shown). Movement of the carriage may be arrested by a cable (116), Fig. 14 (not shown) wrapped around column 65 and which can be tensioned by an eccentric (128) operated by a handle (127). The electrodes operate in an oil bath 99, the ends 101 of which have openings 102 with oil seals 103 enveloping the rolls. The latter are made from forged steel and after machining parallel grooves (32), Fig. 3 (not shown) and keyways (38), the rolls are heat treated before the grooves are tapered by the electro-erosion process.
