Filed: 1920-10-16
Abstract: 178,147. Boyd, F. A. Oct. 16, 1920. Sound magnifying and directing appliances. - A horn for a gramophone or megaphone is connected to the source of sound by a tube 2, 3 bent back on itself to form one or more adjacent bends. The connection between the tube and the horn is by a straight inclined tubular member 4. which is of unrestricted cross-section in passing from the tube to the horn. In the example, the horn is flattened and substantially at right-angles to the tube, and the axes of the horn and the tube intersect on the member 4 which is disposed at an angle of about 45‹ to each, the arrangement being adapted to fit in a rectangular box, for example, a gramophone casing.

Title: Improvements in the manufacture of esters from sperm oil
IPC: C11C1/04
Filed: 1951-12-17
Abstract: Neutral unsaturated fatty alcohol fatty acid esters are obtained by splitting the glycerides in sperm oil to form free fatty acids whilst leaving the said esters substantially unattacked by treating the sperm oil with water at a temperature not above 250 DEG C., and under pressure, in the absence of fat splitting agents, until substantially the whole of the glycerides contained in the sperm oil have been split, 200 DEG C. is the preferred temperature.  Glycerol is removed from the products as an aqueous layer and fatty acids removed from the organic layer by neutralization, solvent extraction (which also removes small amounts of fatty alcohols) or distillation.  During distillation the fatty alcohols may be re-esterified with the fatty acids and additional fatty alcohols may be added.  In examples sperm oil is autoclaved with water in (1) at 210 DEG C. for seven hours, aqueous glycerol removed and fatty acids extracted from the oil with methanol and in (2) at 200 DEG C. for eight hours, aqueous glycerol removed and fatty acids vacuum distilled from the oil.ALSO:Fatty acids, glycerol and neutral unsaturated alcohol-fatty acid esters are obtained by splitting the glycerides in sperm oil, whilst leaving the unsaturated esters substantially unattacked, by treating the sperm oil with water under pressure at a temperature not above 250 DEG C. in the absence of fat-splitting agents until substantially the whole of the glycerides of the sperm oil have been split.

[Also in Divisions B4 and B6] A double-crank flying press which may be fitted with tools 2, 3 for cutting, stamping, scoring, drawing or embossing metallic or non- metallic materials comprises tool carrying frames 4, 5 mounted on four pairs of cranks 6, 7, 8 and 9 carried on shafts 10, 11, 12 and 13. The crankshafts are inter-conneoted by gears 16, 17, 18 and 19, 20 and 21. The crank-shafts also carry balance weights 14 and 15, and have means for adjusting the throw of the crank-pins 66, Fig. 11 (not shown), and the radius of the balance weights simultaneously, comprising a right- and left-hand screw which is rotated by a shaft 58 through bevel gearing. In order to make the adjustment the machine is stopped and locked in the position in which the cranks are parallel to the frames 4 and 5, Fig. 12 (not shown), and a shaft 77 is rotated by a hand wheel. This shaft is connected by gearing to adjusting screws for the crank-pins and balance weights mounted on shafts 11 and 13. The movement of the crankpins is transmitted through the frames to the crank-pins mounted on the shafts 10 and 12. The outward movement of the crank-pins is limited by gauging blocks 67. Quick pitch screws connect the crank-pins and balance weights associated with the latter shafts so that the movement of the crank-pins produces a corresponding movement of the balance weights. There are feed rollers at the entry and exit sides of the machine. The feed movement is arrested by a gauging stop 45 rigidly mounted on the frame 5, Fig. 4 (not shown), and to prevent buckling of the strip it is held between clamps 47, 48 which are resiliently mounted on the frames 4 and 5 and which clamp the strip before the tools engage it. To maintain the clearance between the tools one of the frames has a tapered recess and the other has a mating peg which engages the recess as the tools approach the operating position and locks the frames in the correct relative positions. A stripper bar 102, Fig. 13 (not shown), is carried by brackets 103 which are hung on links 106 pivoted to the frame 4 and which are oscillated by eccentrics 105 and roller followers 104.

[Class 120 (ii)] In a yarn or like winding-machine stoppage is effected upon completion of the winding of the package by the engagement of the traverse guide carrier 8 with a lever 55 which is adjustably mounted on a pivoted stop-arm 42 and, when so engaged, is moved into contact with a toothed wheel 84 on the cam-shaft so that the stop-arm is unlatched from the stop lever 35 which is thereupon automatically operated to stop the machine. To ensure a sensitive operation a shoulder 9 on the traverse guide carrier is adapted to engage a cam surface 80 on the lever 55. The lever 55 is in two parts, one, 70, carrying the cam-shaped engaging-surface 80 and the other, 56, being adapted for engagement with the toothed wheel. A coarse adjustment of the mechanism is effected along the arm 42, and a fine adjustment by eccentric mounting of the part 56 and a screw connection of the parts 56, 70. The invention is described as applied to a conventional type of winding- machine, a drop-wire 85 pivoted on the arm 42 being adapted to engage the wheel 84 upon breakage or exhaustion of the yarn to effect stoppage of the machine, and the lever 35 operating to disconnect the spindle-driving clutch and to apply a brake.
