Title: Improvements in and relating to the production of petroleum-like hydrocarbons from fatty acids, glycerides and vegetable and animal oils
IPC: C10G3/00
Filed: 1924-06-18
Abstract: Oils resembling petroleum are obtained by distilling from copper, cast-iron or sheet-iron boilers, fatty acids, or animal, fish, or vegetable oils, or other glycerides mixed with one or more metal oxides or one or more metal chlorides or a mixture acting as a dehydrating and polymerizing agent, followed or not by similar treatment with zinc chloride or other of the above substances more active as a polymerizing agent.  Suitable chlorides and oxides are zinc chloride, calcium chloride, barium chloride, strontium chloride, magnesium chloride, sodium chloride, potassium chloride, tin chloride, quicklime, barium oxide, and strontium oxide.  The operation may be conducted under a pressure of several atmospheres. Reaction commences at 350-450 DEG  C., and the temperature is preferably raised to 500 DEG  C. The condensate is separated from water, neutralized by washing with dilute soda and water, and fractioned.  The still-residue is treated with superheated steam or a solvent to remove heavy oils, and then with water to dissolve out the metal oxide or chloride for reuse.  The residual carbon may be used to produce water-gas, which may be mixed with the reaction gases consisting of hydrogen, hydrogen chloride, and carbon oxides and used to heat the boilers.

Abstract: 354,795. Radiants for gas fires. FORSHAW, A., Gothic Works, Falkirk, MAIN, Ltd., R. & A., 48, Grosvenor Gardens, London, and GELDEREN, F. M. VAN, Enschede, Holland. May 14, 1930, No. 14892..[Class 126.] The inward projections 3 on the rear wall of a tubular radiant for gas fires are so arranged in relation to the apertures 4 as to direct part of the gases through them to the back of the radiant, thereby increasing the luminosity of the rear wall. In the radiant shown, the apertures 4 are of triangular form, and the projections 3 extend with a downward inclination from their upper edges. The radiants are made by filling a porous (e.g. plaster-of-paris) mould with clay slip, allowing the outer part of the slip in contact with the mould to solidify, and then pouring off the still liquid centre. The operator then pierces the plastic tube thus obtained with a spear-shaped tool, which forms the apertures 4 and presses up the projections 3. Projections 3 on the front of the radiant are similarly formed, after which the material at the sides of the ribs 1 is cut away with the tool. The ribs 1 and the herring-bone series of ribs 2 at the back of the radiant, shown in Fig. 3, are embossed on the tube by the mould, which may also form indications of the points where the tool is to be inserted.

Title: Improvements relating to liquid delivery apparatus
IPC: B05B1/12
Filed: 1941-11-25
Abstract: 552,596. Spray-producers ; nozzles. SMITH, F. Nov. 25, 1941, No. 15164. [Class 69 (iii)] Liquid delivery apparatus such as hose pipes, medical spray and jet apparatus is provided with a nozzle wherein the bore is associated with means for admitting air to the centre of the liquid stream, the air admission being induced by and proportionate to the volume and velocity of the passing liquid. As shown in Fig. 2, the liquid passes through orifices 13 in a fixed plug 7, passages 15 in a rotatable washer 14 and thence through the outlet nozzle 4. When the passages 15 register with the orifices 13 a jet of liquid, mixed with air entering through channels 8, 10, issues from the nozzle but this may be converted into a spray by rotating the washer 14 in either direction so as to obstruct the direct passage of the liquid and divert it along inclined recesses in the washer before passing through the passages 15. According to the direction of diversion, a spinning movement in one direction or the other is imparted to the spray. The rotatable washer 14 may be modified by providing it with two pairs of oppositely inclined passages instead of the straight passage 15 and inclined recesses. In a further embodiment, Fig. 8, the nozzle 4 carries a rotatable auxiliary nozzle 14 provided with a straight outlet bore 15 and with right and left hand helical bores each communicating with the bore 15. In the position shown, the liquid, entering at the bore 2 issues from the bore 15 in the form of a jet. To convert this jet into a spray having either a clockwork or counter-clockwise spin, the auxiliary nozzle 14 is given a partial rotation to cause the liquid to pass through one of the helical bores, splitting up the liquid into a rotating spray, air entering at the bores 8, 10. By adjusting the nozzle 4 backwards or forwards in relation to the air channel 10 the effective bore of the nozzle may be varied or the water stream completely cut off.

Movement of the support in one of the planes is resisted to a greater extent than movement in the other plane. A headset comprises an acetal resin headband 1 provided with two slidable metallic adjustment members 2. Two side arms 4 each support a mounting member 5, 5<SP>1</SP>. The side arms 4 can be rotated to be parallel with the headband 1 for transport purposes. The mounting members 5, 5<SP>1</SP> are retained on the side arms 4 by spring clips 6. Pips on the side arms 4 and a series of holes in the clips 6 permit adjustment of the side arms 4. Alternatively the mounting members 5, 5<SP>1</SP> may be fitted to spectacle side frames. A cable 7 for earphone and microphone transducers emerges from the lower face of mounting member 5 and carries a clothing clip 26. A microphone boom tube 8 is of fireproof material such as P.T.F.E. and carries a metallic member 9 for dissipating heat, e.g. from a cigarette lighter. The member 9 also retains an acoustic filter to reduce the effect of implosive sounds produced by the user. The tube 8 is rotatable about its mounting axis and can be slid vertically within a snout 25. The tube 8 may be removed from the snout 25 for cleaning, or for personal issue where the headset is worn by several users. The snout 25 couples the boom 8 to a microphone transducer 24 (Fig. 3). The support 10 (Fig. 2) is of moulded plastics and has a tubular extension 11 within which a metal tube 12 is a tight fit. The tube 12 is capable of rotation through about 200 degrees, determined by a stop pin 13 movable in a slot 14 in the support 10. At the outer end of tube 12 is a part-spherical metal member 15 which fits into a cavity 16 (Fig. 3) in the mounting member 5. The arrangement is such that the support 10 can be moved through a limited arc B-B (in use in the vertical plane) and can also be moved through a smaller arc (C-C), Fig. 3c (not shown), perpendicular to the arc B-B. Movement through the arc C-C is less stiff than movement through the arc B-B or rotational movement. The sound exit 17 of the earphone may be shaped for insertion in the user's ear but preferably is in use covered by a removable eartip 18 (e.g. of P.V.C.) which merely rests on the ear. The earphone has a red dot 22 (see Fig. 2b, not shown), which the user arranges to coincide with a cut-out 23 in the eartip 18. In use, the sound exit may be swung slightly outwards from the user's ear. Where, as shown, two mounting members 5, 5<SP>1</SP> are provided, only one carries a microphone.
