Title: Improvements in electromagnetic instruments of the movable iron type
IPC: G01R5/14
Filed: 1925-05-07
Abstract: 256,328. Martin, A. J., and Furderer, E. R. May 7, 1925. Electromagnetic current meters of the moving- iron type have the spindle formed in part of, or carrying or surrounded by, very soft iron of low coercive force and of higher retentivity than that of the moving iron, both irons being of low coercive force and hysteresis. Hysteresis errors are thereby eliminated. The invention is shown applied to the instrument described in Specification 237,036. The spindle 3 is surrounded bv soft iron 5 and carries the moving iron 7 by means of lugs 8. The fixed iron 1 is mounted within a tube 2, and is preferably of lower hysteresis value than either of the other two irons.

Title: Process of producing nicotinamide
IPC: C07D213/81
Filed: 1942-08-31
Abstract: Nicotinamide is prepared by heating nicotinic acid with urea Preferably from 1/2 to nearly 1 molecular equivalent of urea is used, the temperature being about 180 DEG  C. to about 250 DEG  C. Reaction may be effected at 180-230 DEG  C. until evolution of ammonia and carbon dioxide ceases and continued with addition of ammonia at somewhat higher temperature.  Unreacted nicotinic acid may be recovered by dissolving the reaction mixture in such an organic solvent as a lower paraffinic alcohol and precipitating with an alkaline earth base such as calcium hydroxide.  In examples, nicotinic acid and urea in molar ratios of 1 : 1, 2 : 1, and 4 : 3 are heated at from 180 to 235 DEG  C.  Ammonia may also be present or passed into the mixture after the initial reaction subsides.  The mixture is cooled to 150 DEG  C., poured into alcohol, and calcium nicotinate precipitated by calcium hydroxide.  The solution is treated with decolourizing carbon and evaporated or further cooled to obtain the amide.  Alternatively, the amide and unconverted acid are recovered by distilling the reaction mixture under reduced pressure.

Body 3 may then be clamped and body 2 undamped so that on switching off the voltage the tube relaxes to its former length and so causes a step movement at the other end of the tube. A rod 10 assists in the alignment of the system. In a modification (not illustrated) a third magnetic clamp is incorporated. In the embodiment of Fig. 3 (not shown), movement of a diaphragm (29) causes a contacting ball (34) and rod (33) to produce movement of the corresponding clamping body (3). In the embodiments of Figs. 4, 5 (not shown), rods (48, 56) are mounted for motion relative to flexible ring seals (46, 47, 54, 55).
