Title: Improvements in and relating to electric distant reproduction of rotary motion
IPC: G08C19/38
Filed: 1936-08-04
Abstract: 471,576. Electric control. ELLIS, L. S. E. (Schloemann Akt.-Ges.) Aug. 4, 1936, No. 21483. [Class 40 (i)] In a system for reproducing at a distance the motion of a rotary member, e.g. a device 2 for adjusting the nip of milling rolls, the transmitter 3 is a rotary-field machine, the rotor of which is driven by the motor 1 that drives the adjusting device and which thus generates 3-phase currents of a frequency depending on the difference in the speeds of rotation of the motor 1 and the rotary field. These currents are fed to a commutator type frequency changer 4 which is driven by a synchronous motor 5 and so produces threephase currents, the frequency of which is proportional to the speed of rotation of the motor 1, and which drive a synchronous motor 6 which has a strong damping winding and acts as the receiver and drives a device 7 in sight of the operator who controls the motor 1 by means of the switches 10 and 12. The receiver 7 may alternatively control the motor 1.

Patent GB-673330-A (GB)
Title: A process for the simultaneous preparation of sodium carbonate and calcium oxide
IPC: C01D7/12
Filed: 1950-09-01
Abstract: Sodium carbonate is produced by fluidizing a bed of finely divided sodium bicarbonate with the hot carbon dioxide-containing effluent from a reactor where calcium carbonate in a fluidized state is preheated and decomposed to calcium oxide in a current of heated air. The calcium oxide reactor preferably contains more than one fluidizing compartment, at least one being used for preheating the carbonate which successively passes through preheating, calcination and air preheating zones.  Fuel is injected into the calcination compartment and the gases discharged from the reactor at 400-625 DEG C. may be passed directly to the sodium carbonate reactor without separating entrained calcium carbonate particles, whereby the sodium carbonate reactor is maintained at 200-350 DEG C.  The solid products from the two reactors may be mixed together with water, such as that employed to work the effluent gases from the calcium carbonate reactor, to yield sodium hydroxide and calcium carbonate, the latter being recycled.  Both sodium bicarbonate and calcium carbonate may be employed in a moist condition.  Specification 642,036 is referred to.

[Class 38 (v).] Rotation of a sand glass 9 into its operative position closes and latches a switch 3, 4 and also raises a ball 7 in a cylinder 6, fixed relatively to the sand glass, into its upper position ; after a time interval the displacement of centre of gravity produced by the movement of the sand causes a slight further rotation of the members 9, 6 and releases the ball which falls and trips open the switch. The sandglass 9 and cylinder 6 are mounted on the same axle 5 which also carries a pinion 10 which may be driven in one direction only by a pushbutton 12 and rack 13. When the cylinder 6 is rotated in a clockwise direction from the position of Fig. 2, a circular spring guide 15 first prevents the ball 7 from falling out of the cylinder 6, and another guide 18 which can project into one or other of two slots 6a in the cylinder 6 prevents the ball from falling through the cylinder after the horizontal position is passed. The cylinder and sandglass are rotated through approximately 170‹ the cylinder then resting against the top end of the spring 15, and the ball resting on the top end of the guide 18.
