Patent GB-497102-A (GB)
Title: Improvements in or relating to remote control systems
IPC: H04L13/18
Filed: 1937-07-10
Abstract: 497,102. Synchronous movements. STEVENS, A. H. (International Business Machines Corporation) July 10, 1937, No. 19212. [Class 40 (iii)] Means 20 for releasing a controlled element 18 in response to periodic single impulses are maintained operated during the intervals between successive impulses. The impulse is originated by the transmitting distributer brush contacting with a segment 1 and causes a thermionic relay 130 at the receiver to pass current to energize the magnet 20, which releases the receiving distributer brush 18 on segment 2. The lead of the receiver is neutralized by delay in the relay 20 and slip in the drive. At synchronism the next discharge of the relay after starting passes to segment 1 and replenishes the charge on a condenser 24 to maintain the magnet 20 operated and the catch 21 withdrawn. When synchronism fails, the charge is not replenished adequately and the catch stops the brush on segment 2. Starting. Received signals build up a charge on a condenser 58 faster than it leaks off through a winding 57, and thus energize a relay 50. This removes the short circuit on a primary 33 and short circuits a winding 56 to compensate for the added impedance. The relay also connects power to a motor 19 driving the distributer and, if required, to the motor driving a typewriter. When signals cease, the charge on the condenser 58 is not replenished and the relay releases to restore the circuits to the initial condition. Type-printing telegraphs. A number of stations are connected over a line 30, 31 and actuation of one operates all. A key 156 is provided for each character and operates a printing contact 157, which is also connected to a corresponding segment 4 of the distributer and can be operated by current received from that segment. When a key is depressed, a push rod 155 closes a switch 154 which operates a magnet 150 to hook a latch 151 over the end of the depressed key and hold it down. It also prevents the depression of other keys. During reception the key board is quite free. Besides energizing its corresponding segment 4, the printing signal energizes a non-repeat relay 140. This disconnects a winding 147, which is of too low resistance to place across the line, and cuts the holding current off the winding 152 of the magnet 150, which releases to permit a spring 183 to withdraw the latches 151 and release the keys. To prevent false repeat signals when a key is inadvertently held down, the relay 140 connects to earth sending bus-bar 138 and any connected segment except the synchronizing segment. When the key is released, the switch 154 is opened and leaves the circuits in the normal condition. Specification 492,705 is referred to.

Title: Improvements in or relating to the treatment of the products of the catalytic conversion of carbon monoxide and hydrogen
Inventor: WENZEL WILHELM
IPC: C07C27/22
Filed: 1950-08-09
Abstract: Products of the hydrogenation of carbon monoxide at elevated pressure in the presence of iron catalysts to yield alcohols and hydrocarbons are treated to separate the oxygenated compounds from the products or a fraction thereof and the separated compounds are subjected to mild hydrogenation, whereby malodorous impurities are hydrogenated while the alcohols are substantially unaffected.  The separation may be effected by extractive or azeotropic distillation or by solvent extraction with, for example, methanol or its aqueous mixtures, ethanol, polyhydric alcohols, acetates or formates.  The synthesis product may, for example, be separated into fractions of 70-180 DEG , 180-220 DEG  and 220-350 DEG  C. and each treated with a different solvent.  Solvent is preferably removed prior to the hydrogenation which may be effected at 50-300 atmos., and 150-270 DEG  C. with catalysts containing copper and chromium or chromium oxide, calcium or barium oxide or nickel.  The copper barium chromite catalyst prepared according to U.S.A.  Specifications 2,089,433 and 2,129,507 may be used at 226 atmos. and 220 DEG  C.  Liquid or vapour phase hydrogenation may be used and dilution with solvents such as dioxane. The hydrogen may be obtained from the products of reacting the synthesis gas or tail gas with steam.  In examples: (1) water gas is treated at 26 atmos. and 182 DEG  C. with an Fe-Al2O3-K2O catalyst, the products separated into an oil and an aqueous layer, the former distilled, and the 135-380 DEG  C. fraction extracted with methanol in a continuous 7-stage counter-current extractor, small amounts of water being added.  The extract is freed from solvent, hydrogenated at 121 atmos. and 220 DEG  C. with a copper barium chromite catalyst, fractionated and distilled; (2) the oily products of a synthesis are distilled to give a 170-220 DEG  C. fraction which is extracted and the extract hydrogenated at 181 atmos. and 240 DEG  C.; (3) synthesis is effected with the catalyst suspended in the gas introduced in turbulent flow at the foot of a column, and the aqueous part of the product is azeotropically distilled to yield an impure alcohol product which is hydrogenated; (4) the same fraction is used as in (2) and is distilled with butylene glycol to carry over an azeotropic mixture with the hydrocarbons before subjecting to hydrogenation; (5) a similar fraction is extracted in a distillation column with a -naphthylamine added as liquid at the top, the mixture withdrawn at the base being distilled to recover oxygenated products which are hydrogenated.
