In one embodiment, 35-50% of the mother liquor obtained by separation of the precipitates is recycled to provide a liquid : solid ratio of material entering the reactor of between 2À5 : 1 and 5 : 1, and such that the liquid phase in the reactor is between 60 and 70% of the total mass. Barium carbonate may be added to the mother liquor to precipitate residual SO 4 =. In operation, vessel (1) is fed with metered phosphorate (2), Na 2 SO 4  (3) and 98% H 2 SO 4  (4). The ingoing liquid phase is mixed with wash water (5) issuing from filter (6) and mother liquors (7) in pipe (8). The remainder of the mother liquor is fed via (9) to tank (10) for subsequent polymerization. Water from (11) washes the filter cakes of gypsum, which are expelled at (12).

[Class 98 (i)] [Also in Group XXIV] A slidable rod 1 carrying a fluorescent screen in an X-ray apparatus is associated with a locking member which either allows free sliding of the rod, or allows movement in one direction only, or locks the rod against all axial movement. The locking member comprises a ring 2 surrounding the rod with a small amount of clearance, pivoted at 4 to a supporting carriage 6 and spring- pressed at 11 into engagement with the edge 10 of a groove 8 in a rod 9. As shown, the rod 1 can slide freely, but on moving rod 9 slightly to the left the ring 2 will be spring held in engagement with rod 1 to allow it to slide to the right, but increasing the locking pressure on movement to the left. Further movement of rod 9 will bring edge 14 of groove 8 into contact with ring 2, and press it into engagement with rod 1, which is then locked against all axial movement. Rod 9 may be moved by a rotating cam, or may be replaced by a cam acting directly on ring 2.

Title: Improvements in telephone exchange systems
IPC: H04M9/00
Filed: 1923-12-28
Abstract: 230,573. Western Electric Co., Ltd., (Capek, A., and Broeck, F. van den). Dec. 28, 1923. Addition to 228,593. Manual exchange systems. -The parent Specification relates to a local operator's cord circuit, Fig. 2, in which the talking circuit is completed by sleeve relays 31, 47 which are not energized when the associated plug is put into a busy jack. The present invention consists in a toll operator's cord circuit, Fig. 1, with means whereby the toll operator after plugging into a local connection, can break it down at will by releasing relay 31 or 47, a characteristic signal being given to the local operator. If the calling plug 200 is put into an idle line, relays 201 - - 203 pull up in series from the sleeve and lamp 207 glows, ringing key 206 is then thrown, and when the called party replies, relay 209 puts out lamp 207. If the wanted line is busy with a toll call, a special busy tone 210 will be connected to the sleeve. If it is busy with a local call, the plug 200 is inserted, but only relays 201, 202 pull up, relay 203 being unable to energize when the circuit is shunted by the low resistance of relay 31 or 47 in the local cord. As a result, lamp 207 is flashed over interrupter 211. The toll operator may now talk to the local subscribers by throwing key 212 or to the long-distance line without disturbing the local subscribers by throwing in addition key 213, which disconnects her from the calling side. The local connection is broken down by throwing key 205 which short-circuits relay 31 or 47 of the local cords and energizes relay 203. When key 205 is released, relays 201 - - 203 hold up since relay 31 or 47 cut in its high resistance winding on falling back and is unable to re-energize when shunted by relays 201 - - 203. Relay 209 is connected up by relay 203 and cuts off lamp 207. In the local cord, the relapse of relay 31 or 47 and consequently of relay 36 or 90 lights the supervisory lamp 132 or 116', and at the same time relay 49 pulls up from battery over relay 209 in the toll cord, makes the flash circuit for lamp 51 and holds up relay 44. If the other party in the local call fails to hang up, the local operator can explain the situation by throwing her listening key 42.

Numerous embodiments are described of broadly two types, in which, as shown, the trigger condenser 15 is charged at the same time as the main condenser 13, or in which the local circuit is made and the trigger condenser charged only on break-down of the spark gap 14 which is serially connected between the two condensers. The spark gap 14 and the secondary winding 17 may be serially or shunt connected in the main discharge circuit and the transformer may be auto-connected. Where, in the case of discharge lamps, a running supply is needed, this may be connected serially with a choke across the output connections 18, 19, or in the main discharge or transformer secondary winding circuits.
