Abstract: 107,569. Grier, T. April 13, 1917. Hand and like lanterns.-An outdoor or like lantern is provided with a large flame chamber D having an exhaust flue and semi-air-tight means for supplying an imperceptible amount of cold air. A small chamber J is arranged above and behind the flame chamber and communicates with air chambers H, K and with the cowl of the lamp. Almost the whole of the air supply for combustion passes from the chamber H through the burner cone 5¢ to the flame. Air passes through the perforated base-plate and through apertures 20, 12 to a chamber K and thence upwards through ducts 12¢ in a plate 11 to the chamber H and the chamber J. Perforations in the rear of the chamber H allow the passage of air from the chamber J to the chamber H. The apertures 20, 12 may be closed by means of shutters. The oil reservoir 7 carrying the burner 5 may be formed in one with a vertical plate 3¢ and a horizontal plate 6 so that, when the reservoir is inserted from the rear into the guides on the plate 11, the plate 3¢ closes apertures in the rear of the flame chamber and the plate 6 closes the top of the chamber H. The plates 3¢, 6, may, however, be hinged or otherwise attached to adjacent parts. A very small quantity of cold air can pass between the plates 3¢, 6 and their seatings when the plates are in their normal positions. The rear end of the lantern is provided with a sliding door 1 having a sliding cover for enabling the flame to be inspected through a glass pane in the rear wall of the flame chamber.

Lantern shutters.-A plurality of mirror; 21 - - 25 are mounted on vertical pivots in a casing 3 arranged in front of the lamp face and are actuated either by hand or by the turning of the vehicle to cause the beam to sweep to either side. The casing is provided with lugs 5 carrying a band 6 adapted to encircle the lamp 1 and be tightened by a nut and bolt 7. A glass front 8 and a flange 9 to the rear compressing a ring 10 of rubber against the frame of the lamp render the casing weather-tight. Crank arms 28 fixed to the lower spindles 13 - - 17 of the mirrors are linked together so that the mirrors move in unison, and the spindle 13 passes through the bottom 12 of the casing and carries a bell crank lever 27 actuated by a rod 31 from the steering gear drop arm 38 through a slotted curved arm 37. A link 30 connected to the other arm of the bell crank lever 27 communicates motion to the mirrors of the other lamp. The rod 31 may be raised to any point in the slot of the curved arm 37 to vary the deflection by a cord 43 connected to a control handle 40 provided with a ratchet 41, and by lowering the rod 31 so that its end coincides with the axis of the drop arm 38 the deflecting mechanism is put out of action. A stop may be arranged to limit the movement of the mirrors so that with maximum deflection a small amount of light still passes in the forward direction. The rod 31 may be disconnected from the bell crank lever 27 by removing a screw 36 and the mirrors worked by hand through a Bowden wire such as 44. The mechanism connecting the mirrors with the steering gear may be constructed as described in Specification 278,464, [Class 75 (iii), Lamps &c., Details of], to turn the mirrors of one lamp only at a time. The mirrors are made reflecting on both sides and may be arranged to occupy a circular casing instead of the rectangular casing shown.

Title: Improvements in the process for the manufacture of d./-nerolidol
IPC: C07C33/025
Filed: 1924-03-17
Abstract: d-1-Nerolidol is prepared by reducing methyl-ethinyl-homogeranyl-carbinol by means of hydrogen in the presence of finely divided nickel, platinum, or palladium. Nerolidol is thus identified as methyl-vinyl-homogeranyl-carbinol.ALSO:d-l-Nerolidol is prepared by condensing dihydro-pseudo-ionone with acetylene to form methylethinyl-homogeranyl-carbinol and reducing this compound; nerolidol is thus identified as methyl-vinyl-homogeranyl-carbinol. In an example the condensation with acetylene is effected by means of sodium amide or powdered sodium in absolute ether; in place of sodium amide and acetylene, sodium acetylide may be used: the reduction of the acetylene bond is effected by adding sodium and water to the ether solution; it may also be effected by sodium and alcohol or by hydrogen in presence of finely divided nickel, platinum, or palladium.  The nerolidol is converted by acid agents such as acetic anhydride into farnesol and by oxidation with chromic acid into farnesal which can be identified by means of its semicarbazone. Nerolidol may be used as a perfume or for the preparation of other perfumes.
