Abstract: 1,026,836. Clutch control. A. W. JEFFERY. Jan. 13, 1965 [Jan. 13, 1964], No. 1481/64. Heading F2L. A tractor clutch operating mechanism is so arranged that the clutch may be engaged for a predetermined time interval or tractor travel and then automatically disengaged, and may be modified to provide for fully automatic cyclic engagement and disengagement of the clutch. The arrangement shown provides for both semiautomatic and fully automatic operation, a motor 28 under the control of a switch 27 driving three rotary cams 29, 33, 45 controlling switches 32, 30, 44, cam 29 opening the normally closed switch 32 once per revolution, while cams 33, 45 respectively hold the normally open switches 30, 44 closed for approximately one-third or one-half of a revolution. For semiautomatic operation a master switch 37 is moved from the open position shown to close a first pair of contacts, when the motor 28 rotates the cams 29, 33, 45. A selector switch 46, 48 enables either of the cams 31, 35 to be rendered effective according to the desired time of clutch engagement, at the end of which switch 30 or 44 is opened to disengage the clutch. A switch 27 is momentarily closed to restart the motor 28. For fully automatic operation switch 37 is rotated further to close a second pair of contacts and short circuit switch 32 so that motor 28 and the control cams rotate continuously for cyclic clutch engagement and disengagement. The cams 31, 45 control a solenoid valve operating a pneumatic or hydraulic piston and cylinder actuator coupled to the clutch control lever, Figs. 2 and 3 (not shown).

Title: Process for separating di-acetylene from gases containing acetylene
IPC: C07C7/11
Filed: 1933-01-17
Abstract: Gases, produced by the thermic treatment of hydrocarbons which contain acetylene and small quantities of diacetylene are freed from the latter by washing them at temperatures between 0 and -30 DEG  C. with ketones or mixtures thereof with other solvents, e.g. aldehydes, the quantity of solvent only being sufficient to dissolve a small proportion of the acetylene.  In an example, a dry gas mixture containing acetylene, hydrogen, methane, nitrogen and diacetylene is washed with acetone, the quantities of acetylene and diacetylene dissolved being stated.  By reducing the pressure on the saturated solvent or by passing a stream of nitrogen through it, the acetylene and diacetylene are recovered. The diacetylene may also be separated by freezing, or by raising the temperature of the solution.  The gases may be treated in immersion columns in which the gases and solvent flow in countercurrent.ALSO:Gases, produced by the thermic treatment of hydrocarbons which contain acetylene and small quantities of diacetylene are freed from the latter by washing them at temperatures between 0 and - 30 DEG  C. with ketones or mixtures thereof with other solvents, e.g. aldehydes, the quantity of solvent only being sufficient to dissolve a small proportion of the acetylene.
