Patent GB-363948-A (GB)
Title: Improvements in or relating to the manufacture of alkali metal acetates
Filed: 1931-05-18
Abstract: Hydrogen is produced by the action of acetylene and steam on alkali hydroxide.ALSO:Alkali metal acetates are obtained by the action of acetylene and water on alkali metal hydroxides at a moderately elevated temperature and at atmospheric or elevated pressure, from 1-4 molecular proportions of water being used with each molecular proportion of acetylene.  The water may be introduced as vapour, liquid, or alkali solution, and the acetylene may be diluted with indifferent gases such as hydrogen, nitrogen, methane, or other gaseous hydrocarbons.  Using sodium hydroxide, temperatures between 275-325 DEG  C. should be employed, while temperatures between 200-350 DEG  C. may be employed when potassium hydroxide is used. The reaction may be carried out with a fused or a solid, comminuted reaction mixture.  With sodium hydroxide, it is preferred to allow the reaction to proceed until two-thirds of the alkali is converted to acetate, whereupon the product is dissolved in water, the acetate crystallized out, and the excess of hydroxide reconcentrated and returned to the process; this mode of operation may also be continuous.  A mixture of sodium hydroxide and potassium hydroxide may be used in any desired proportion and, conveniently, in the liquid state.  In this case, the acetate may be recovered solely as sodium acetate by adding sodium hydroxide to the dissolved reaction product, or by stopping the reaction when the amount of acetate formed is equivalent to the sodium hydroxide taken, and then crystallizing from water.  Examples are given.  Hydrogen produced by the process may be recovered for use elsewhere.  The Specification refers to the production of acetates (a) by the action of acetylene on anhydrous alkalies, and (b) by the action of diluted acetylene under pressure on dilute aqueous alkalies.

Title: Improvements in and relating to buttonhole sewing machines
IPC: D05B3/06
Filed: 1930-05-20
Abstract: 354,420. Buttonhole sewing-machines. HUGHES, R. M., 72, Cannon Street, London.-(International Button Hole Sewing Machine Co.; 502, Harrison Avenue, Boston, U.S.A.) May 20, 1930, No. 15459. [Class 112.] A buttonhole sewing-machine is provided with an attachment by which a flybar buttonhole may be made with or without an " eye " at the end opposite the flybar. The double lateral movement involved in making the " eye 3, Fig. 8, may be eliminated so that when the stitch-forming mechanism comes to the end of the buttonhole, it simply makes its usual rotation, making the end as at 5, Fig. 9. The work is held in the usual clamps 12. The relative feeding movement of the work between the clamps 12 and head 13 is effected by the usual cam mechanism 17. The cam 17 is driven from a worm gear fast on the shaft 20. The cam housing 18 is formed with a boss 21 in which is journalled a stud 22, the upper end of which has an arm 23 carrying a shoe 24 engaging a groove 25 in the frame 11. The lower end of the stud has a lever 26 carrying a follower 66 engaging the groove 27 in the cam 17. This groove is of the usual shape for forming a flybar buttonhole with an eye as in Fig. 8, the cam portions 28, 29, 30 effecting the necessary feed displacements. To make the buttonhole without the eye, as in Fig. 9, the pin 66 is withdrawn from the groove 27, so rendering the double cam portion 30 which carries the eye ineffective. The mechanism for effecting this is as follows. A lever 31 is pivoted to the lever 26 and connected to the follower 66. The pin 66 is mounted to slide vertically in a boss 34 on the lever 36. The pin 66 is withdrawn from the groove to miss the cam 30 by a lever 31. The lever 31 carries a pin 35 engaging the recess 37 in the cam housing 18 so that when the pin 66 is withdrawn from the groove 27, the cam housing and head 13 are held from lateral vibrating movement and can move only in the direction of the length of the buttonhole. Automatic effecting of this effect is ensured by the cam face 43 acting on a spring-pressed pin 39 on the arm 45.
