Patent GB-668612-A (GB)
Title: Method of producing coarsely crystalline sodium carbonate monohydrate
IPC: C01D7/35
Filed: 1950-08-09
Abstract: Coarsely crystalline sodium carbonate monohydrate is produced by mixing sodium carbonate from the ammonia soda process, preferably immediately after calcination and while still hot, with the water required for the formation of the monohydrate, e.g. 20-50 per cent preferably in the form of steam, the mass being kept in motion at 70 DEG C. while maintaining the water content, suitably by working in a closed apparatus.  Excess water is preferably used which may be removed by passing a current of warm air over the mass at completion. The resulting coarse grained monohydrate may be calcined at about 130 DEG C. to give coarse grained sodium carbonate.  An example relates to the treatment of calcined ammonia-soda with steam in a closed rotating drum until 20 per cent of water has been absorbed.  The temperature rises to 105 DEG C., the steam is cut off and the temperature maintained between 90 DEG -100 DEG C. for 50 minutes. Air is passed over at 40 DEG -60 DEG C. to remove excess water.  A further example relates to treatment with water at 80 DEG C.  It is stated in the Specification to be known that granulated dense soda may be produced by mixing soda of low bulk density with 16 per cent of water in a screw mixer and subsequently drying at 135 DEG -190 DEG C., the steam from the drier being condensed and recycled to provide the 16 per cent of water required for hydration.

Title: Improvements in keyboard impulse transmitters for use in teleprinting systems
IPC: H04L15/16
Filed: 1934-07-06
Abstract: 423,155. Type - printing telegraphy. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. July 6, 1934, No. 19935. Convention date, July 6, 1933. [Class 40 (iii)] In a keyboard transmitter in which contact members corresponding to the characters co-operate with a rotating contact cylinder, the operation of a contact member into engagement with the contact cylinder locks the contacts of all the other characters out of engagement with the cylinder until the transmission of the impulses of the character has been completed and the contact has been positively disengaged from the cylinder by a device which produces said disengagement independently of whether the corresponding key has been released or not. A key 3 can be depressed when a locking bar 16 common to all the keys and carried on a pivoted arm 5 moves to the right by the engagement of a roller 9 with a flat surface 11 of a constantly rotating cam. When a key is depressed a projection 18 on a pivoted member 17 individual to a key depresses a pivoted member 19 unlatching a spring biassed contact member 7 which is held from engagement with the contact cylinder by the bar 16 until the roller 9 engages the cylindrical portion 10 of the cam. The bar 16 on returning to the position shown allows the contact member 7 to engage contacts corresponding to the key depressed, locks the unoperated keys by entering the recesses 8 of the members 17 and by actuating to the left, the arm 17 of the depressed key releases the arm 19 from the projection 18. When the impulse combination has been transmitted the roller 9 again engages the flat surface 11 so that the locking bar 16 frees the keyboard and moves the lower end of the spring 7 to the right so that it is latched by a nose 20 on the member 19. No further impulses are transmitted until a key is depressed and this depression may be effected if the previous key has not returned to its inoperative position.

In a conveyer which is rotatable about a pivot 9 at one end whilst simultaneously moving rectilinearly to a small extent, the pivot 9 comprises a pin passing through a bore, the pin and the bore being separated by a bush 11 of resilient material which is compressed or relaxed to allow the required rectilinear movement to occur. As shown, the conveyer frame 6 is mounted on a main frame 10 by rubber-bush mountings 9. In a modification (Figs. 5 and 6, not shown) a link (12) may be disposed at each side between the frames 8 and 10, there being a rubber bush mounting at each end of the link (12). The invention may be applied to the stacking apparatus described in Specification 1.239,441.
