Title: Improvements in or relating to the recovery of ammonia and amines from their salts with organic acids
IPC: C01C1/08
Filed: 1934-04-04
Abstract: Aliphatic amines or ammonia are recovered from their salts with organic acids by heating the salts to temperatures at which the basic and acidic components are set free, removing one of the components concurrently with its liberation and separately removing the other component either simultaneously with or after the removal of the first component.  The components may be separated by simple, fractional or azeotropic distillation, the last method being employed if the difference in volatility is small, when a substance forming an azeotropic mixture with either the acid or the base is added to the mixture.  Suitable salts comprise the acetates of ammonia, methylamine, and ethylene diamine ethylamine and ammonium propionate. In the case of the acetate of ethylene-diamine, the separation is facilitated by this addition of toluene or tetrachlorethylene which form an azeotropic mixture with the acid.  The salts may be decomposed in aqueous solution or in suspension in other inert liquids; decomposition temperatures of 80--160 DEG  C. may be employed.ALSO:Ammonia or aliphatic amines are recovered from their salts with organic acids by thermally decomposing them and separating the components by simple fractional or azeotropic distillation.

Abstract: 200,911. McLachlan, N. W. April 20, 1922. Relays.-A contact-making arrangement whereby a small movement due to an automatic telegraph transmitter, such as a Wheatstone transmitter, produces a large movement of a contact arm, comprises a continuously-driven fly-wheel A fast to a clutch-member C adapted to be engaged by a second clutch-member D carrying a contact arm N when the member D receives a small longitudinal movement. The member D, rotatably mounted but held against longitudinal movement on a rod F, is normally kept out of engagement by a spring G. The other end of the rod F is secured to a band I with blocks K in contact with a driven drum J. Normally, the friction is insufficient to move the rod to the right, but the friction is increased when the signalling current impulse passes through a coil, not shown, carried by the drum J, the operation being as described in Specification 176,932. The clutch-members may carry coils Q, R, a direct current being supplied to one coil, and the signalling current passing through the other, whereby the frictional engagement of the clutchmembers is increased. Contact N is normally held away from the co-operating fixed contact 0 by a spring P. A modification is described employing an expanding clutch operated by the rod F.

April 9, 1930, No. 11275. Convention date, April 16, 1929. [Class 29.] Absorption machines.-In control devices, particularly for absorption machines, wherein the pressure of the cooling-liquid on a diaphragm serves to actuate an electric switch, gas valve, or other means controlling the supply of energy to the apparatus, the diaphragm is also adapted to control directly or indirectly a pressure-reducing valve for the cooling-liquid. In one arrangement, Fig. 3, cooling-water flows through a connection 2 and conduit 89, controlled by a thermostatic valve 87, and then passes through the reducing valve 66 to the connection 62 to the apparatus, the pressure of the water acting on a diaphragm 18 to actuate a gas valve in a fitting 52 or a tilting switch. The diaphragm 18 is connected to the valve member 66 by straps 67 and its movement is transmitted to the gas valve, switch, &c., by a second diaphragm 19. The thermostatic valve is yieldingly mounted in a casing carried by a bellows 83, connected by a tube 82 to the feeling- member of the thermostat. The thermostat control may be cut out by a manual valve 93 in a byepass. A modification without thermostatic control is described. In the arrangement shown in Fig. 4 the pressure reducing valve 104 is operated by a diaphragm 103 connected by a conduit 107 to the water inflow 100. The pressure in conduit 107 is regulated by a valve 109 controlled by a diaphragm 18 thus giving this diaphragm indirect control over valve 104.

In inking mechanism having an ink transfer roller 12 rotated alternately in opposite directions and feeding ink via a distributer roller 11 at one side thereof to a reciprocated inkreceiving surface 10, means are provided for moving the distributer roller out of contact with the transfer roller (in synchronism with the inkreceiving surface movements) at the required times to prevent a downwardly-directed spray. The roller 12 may be longitudinally vibrated; as shown, in a cylinder press having a reciprocating type-bed from one end of which the table 10 extends, and with a set of forme rollers (not shown) to transfer ink from the table 10 to the type, the roller 12 is supplied from a fountain roller 16 by a ductor roller 13 carried by arms on a shaft 15 oscillated in timed relation with the type bed; a rider roller 17 is also provided, and the size and arrangement of the rollers 11, 12, 13, 17 is such that the roller 17 catches any upward spray from between the rollers 11, 12 or 13, 12, while the rollers 11, 13 catch lateral spray from between the rollers 17, 12; the bearing sockets 35 of the roller 11 are each supported by a block 31 adjustably mounted on the press frame, by a set-screw 33 passing through a horizontal slot 32, for adjusting the roller 11 parallel to the table 10 into contact with the roller 12. As the roller 13 approaches the roller 12 at the start of the printing stroke an arm 18 on the shaft 15 at each side of the press acts through an adjusting screw 20 and thrust-link 21 to rock an arm 23 on its shaft 24; this lifts an arm 26 whose nose 27 bears upwards on a lever 29 pivoted on a stud 30 on the block 31; an adjusting-screw 48 in the lever 29 moves the bearing socket 35 up a sloping face 34 on the block 31 against a spring 36 to disengage the roller 11 simultaneously from the roller 12 and table 10. The roller 12 is now rotated anti-clockwise to take up ink from the roller 13. At the start of the return stroke of the bed the ductor roller 13 is swung towards the fountain roller 16, and the roller 11 falls into contact with the roller 12. As the table 10 approaches (Fig. 3), the roller 12 is rotated clockwise to transfer ink stored on the roller 17 to the roller 11 and thence to the table. The impression cylinder trip-shaft 43 may carry an arm 42 with a pin 41 engaging the lower end of an arm 40 on the shaft 24, to keep the roller 11 disengaged when the impression cylinder is tripped.
