Title: Process for the manufacture of formaldehyde by electro-synthesis from carbon monoxide and hydrogen
IPC: C01B3/34
Filed: 1936-12-18
Abstract: <PICT:0469371/IV/1> In the production of formaldehyde by treating carbon monoxide and hydrogen in an electric discharge, the process is effected at an absolute pressure of less than 0,15 atmosphere; at these pressures anodic light appears, and it is thought that the anodic light effects the synthesis.  The yield is increased by arranging between the electrodes a solid absorbent for formaldehyde, such as active charcoal or silica gel.  In the apparatus shown, electrodes B, B1 are arranged across a reaction chamber A, the space between the electrodes being divided into sections F which are alternately empty and filled with absorbent.  The electrodes may be supplied with alternating current at 20,000 volts.

In the embodiment shown, the sample flow through lines 37, 52, 58 is stilled to allow analysis of the contents of the flow cell of means 40 while the stream is diverted through lines 38, 84 and analysis station 42 to wash the flow cell at station 42.

For a controlled time interval before the making of a measurement, the appropriate valve 74 or 94 is made to connect line 54 or 92 to a pump tube waste line, to  desegment the stream flowing to the corresponding analysis station. In the embodiment of Fig. 3 (not shown), there is a single analysis station, the flow through the analysis station is slowed prior to carrying out the measurement by temporary connection of the effluent line to a pump tube waste line of smaller i.d. than that used for the washing out step, and the stream now flowing at reduced speed is desegmented by means of a connection open to atmosphere.

Abstract: 467,511. Signalling over power circuits. AUTOMATIC ELECTRIC CO., Ltd., and ROSEBY, P. N. Dec. 17, 1935, No. 35012. [Class 40 (iv)] In a system for signalling over the neutral or phase wire of a three-phase alternating current network of the kind described in Specification 435,564, [Group XXXVIII], which employs a spark-gap generator energized by the supply current through a step-up transformer, attenuation is reduced by the provision of two or three generators E located at different points of the network and controlled by different phases. Since the output of such a generator persists only for a fraction of each half-cycle of the supply current, the control by different phases ensures that the generators are effective in succession during each half-cycle, as indicated in Fig. 2. The energizing circuits of the generators include contactors F which may be controlled by relays S in series in a pilot wire or by synchronous motors driven from the supply.
