Abstract: 810,157. Regulating switches. JANSEN, B. Jan. 1, 1957 [Jan. 7, 1956], No. 74/57. Class 38(5). A switch, suitable for transformer tapchanging, comprises a plurality of fixed contacts 31 ... 34 on the inner surface of a cylindrical insulator 28, a rotatable shaft 40 concentric therewith, and a plurality of sector-shaped contact carriers eccentrically pivoted at 73 to the shaft, the movable contacts 75 ... 78 carried thereby being radially movable with respect to the axes 73. Each carrier comprises end plates 70, 71 having gear teeth 72 meshing with teeth 44 on the inside of member 28, and an intermediate insulating member 68 having slots 66 in which contacts 75 ... 78 are slidable. The contacts are carried by arms 55 ... 58 connected by a spindle 54 urged outwards by springs 50 arranged in housings 48 serving as bearings for parts 52, 53 on spindle 54. Rotation of shaft 40 thus rocks each carrier simultaneously and the contacts are changed over from one end position in which, e.g. contacts 31, 75 are engaged to the other end position with contacts 34, 78 closed. In a modification (Figs. 5, 6, not shown), each contact arm engages simultaneously two axially-spaced contacts, and alter-, nate arms are connected to separate spindles as 54, separately acted on by springs. The radial movement of the arms is guided by intervening rollers.

Title: A process for the catalytic hydrogenation of carbon monoxide
IPC: C07C1/04
Filed: 1955-01-04
Abstract: A process for the hydrogenation of carbon monoxide comprises passing a fresh synthesis gas upwardly through a suspension of an iron catalyst in a liquid medium, the catalyst being contained in 2 or more reactors connected in parallel and through which the gas is passed for at least 6 hours at a rate of less than three normal litres of CO+H2 per gram of iron per hour, increasing the rate of throughput of the gas up to a value not exceeding three litres per hour, and thereafter passing the gas through the several reactors in series to convert the process into one of multi-stage operation. Preferably, the reactors are in parallel for a period of 12-72 hours. The catalyst may be prepared by precipitation and drying at 250-400 DEG  C. to obtain a water content less than 0.1 per cent by weight. The carbon dioxide formed may advantageously be removed between stages by using a hot solution of K2CO3.  In examples, reactors were loaded with a catalyst suspension containing Fe and 0.2 per cent of Cu, and 0.4 per cent of K2CO3 and heated to approximately 280 DEG  C. Synthesis gas (CO : H2=3 : 2) was then passed through at an initial rate of 0.9 normal litres of gas per gram of Fe per hour, the rate slowly increasing to 2.2 litres per hour.  After about 48 hours the reactors were connected in series to give a conversion of CO of about 95-98 per cent.
