Title: Process for the catalytic hydrogenation of carbon monoxide
IPC: C07C1/06
Filed: 1950-05-09
Abstract: Hydrocarbons are produced by the catalytic hydrogenation of carbon monoxide over an unsupported iron catalyst, acetylene or other gaseous hydrocarbon having a triple bond, e.g. vinylacetylene or allylene, being present in the feed.  By the addition of the acetylene, a reduction of about 20 DEG  C. in the synthesis temperature is possible with a high yield of hydrocarbons boiling above 320 DEG  C.  The synthesis gas may contain 0.5-10, preferably 0.5-1, per cent of the acetylenic hydrocarbon.  The catalyst is preferably impregnated with an alkali metal salt of a non-volatile acid, e.g. potassium phosphate and/or silicate, equivalent to 1-10 per cent K2O on the total iron, and reduced at 250 DEG  C. with hydrogen and nitrogen at a high rate of flow of 1-2 m./sec.  In an example, the catalyst contains 100 parts iron, 5 parts copper, and KH2PO4 equivalent to 3 parts K2O, reduction being effected to 40 per cent free iron.  Water gas containing 1.5 per cent acetylene is passed at 200 DEG  C. and 100 normal litres/litre/hour.

Abstract: 837,630. Thermionic valve testing; resistance measurement, capacitance measurement. SIEMENS & HALSKE A.G. April 9, 1957 [April 9, 1956], No. 11594/57. Class 37. Thermionic valves are tested in manufacture for disconnections, short circuits, pin insulation intermittencies, and incorrect electrode spacing by insertion of each into a holder whereby each electrode is connected to a moving contact of a separate 2-way switch K1 to K7 which are manually operated or automatically operated by selector switch SW so that each switch in sequence has its moving contact on its left-hand fixed contact while the remaining switches have their moving contacts on the right-hand fixed contacts, which-are connected together to input 1 of an amplifier-voltmeter MV, J and alarm indicator S1. An A.C. source HG is connected by one terminal to the remaining terminal 2 of the amplifier-voltmeter, while the source terminals also energize capacitative potential dividers C11, C21 to C17, C27 respectively, corresponding to each switch K1 to K7 and centre connected to the left-hand contacts thereof, so that the reading of the amplifier-voltmeter is a measure of the capacitance between the selected electrode (the heater as shown) and the remainder. Resistances R1 to R6 are connected from the centre points of the capacitative voltage dividers to the input terminal 6 of a D.C. amplifier JV2 operating an indicating and alarm device S3, whose remaining input 5 is returned to line 2-8 over D.C. source B2, whereby the output of JV2 to device S3 represents the leakage current of each electrode in turn towards all the remaining electrodes. The resistances and capacitances are adjustable individually to give a single standard indication for each electrode test in a known standard valve, the indicating devices may have tolerance marked dials for good and bad valves, and indicators or alarms may be arranged to operate for deviations outside a known tolerance range. D.C. amplifier JV1 and indicating and alarm device S2 is connected in series with a D.C. source B1 oppositely poled to B2, and resistance R7 to the left-hand contact of the cathode switch K7, whereby the resistance between a heated cathode and all other electrodes may be determined. Valves may be vibrated during the test cycle and microphonic voltages at the inputs of the test amplifiers may be fed to a loud-speaker. Neon lamps may indicate the particular electrode selected for test.

Abstract: 642,662. Dielectric heating. NAAMLOOZE VENNOOTSCHAP ONDERZOEKINGSINSTITUUT RESEARCH. May 1, 1947, No. 11738. Convention date, March 18. [Class 39(iii)] Rayon cakes or like packages of wound thread 3 are dried by dielectric heating in a H.F. electric field, the cakes being so placed in the field that at least an end face is screened from the field. In order to counteract any uneven heating caused by this arrangement relative movement may be imparted to the cakes or to the field to effect uniform heating. The arrangement shown in Fig. 2 employs three electrodes 9, 10, 11, spaced around the package 12. Voltages 120 degrees out of phase may be supplied to the electrodes to effect a rotation of the electric field in a clockwise direction and the support 13 may also be rotated so as to impart an anti-clockwise rotation to the package. The speed of relative rotation may be selected in proportion to the drying time to effect uniform heating. The packages may be treated in a stronger field and then cooked in a weaker field or allowed to cool in the atmosphere.
