Abstract: 540,133. Catalytic dehydrogenation. DU PONT DE NEMOURS CO., E. I. April 4, 1940, No. 6087. Convention date, April 4, 1939. [Class 1 (i)] [Also in Group IV] Oxy-aldehydes are produced by passing over a de-hydrogenating catalyst the vapour of a glycol ether or ester of the formula CH 2 OXCH,OH where X is an alkyl, alkoxy-alkyl, aryl, aralkyl, phenoxy-alkyl or acyl group. The re-action temperature may be 200-375C. and the pressure may be atmospheric or above, such as 5-1000 atmospheres. Preferably a diluent is used, such as steam, nitrogen or carbon dioxide. Suitable catalysts may be made by fusing copper oxide alone or with another oxide such as magnesium or nickel oxide and reducing the mass; or copper-nickel copper-silicon, copper-zinc chromate and copper-zinc oxide catalysts may be made by precipitation and reduction. Nickel with or without cerium may be used under mild conditions. In examples 1-3 methoxy-acetaldehyde is produced from glycol monomethyl ether by means of the following catalysts:- (a) a reduced mixture of copper oxide, silica and chromium oxide (Cr O 3 ) in the molar ratio 100:10:5; (b) a similar mixture in the ratio 100:50:10; and (c) reduced copper oxide and silica in the ratio 9:1. In example 4 methoxy-methoxy-acetaldehyde is produced from methoxy-methoxy-ethanol, using the catalyst of example 1; and in example 5 acetoxy-acetaldehyde is produced from glycolmonoaceate by the same catalyst.

Abstract: 267,165. I. G. Farbenindustrie Akt.- Ges. March 8, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Aromatic hydrocarbons. - Benzene and other organic compounds of low molecular weight are produced by subjecting the gas and vapour mixtures resulting from the carbonization of coaly materials to the action of catalysts at high temperature and, if desired, with the addition of reducing gases, such as hydrogen, or water vapour. Contact poisons may be eliminated first, for example by passing the mixtures over the oxides of metals, such as zinc, the sulphides of which are not decomposed by hydrogen or water vapour at temperatures above 300‹ C. The gases chiefly treated are aromatic, hydroaromatic or heterocyclic compounds such as naphthalene, higher phenols and carbazole, and the products are mainly lower aromatic bodies, such as benzene and its homologues. The catalysts recommenced are those described in Specifications 277,394 and 283,600, such as iron oxide and aluminium oxide or the oxides of iron, magnesium, molybdenum, zinc, chromium, and/or vanadium; other suitable catalysts are (1) iron, zinc, and aluminium or uranium, and (2) catalysts containing nickel, such as nickel, iron, and aluminium, or nickel, iron, zinc, and chromium. or nickel, iron, uranium, and zinc in the form of vandates. In an example, a solution of ferric nitrate and zinc nitrate in water is poured into an aqueous solution of potassium carbonate. The precipitate is filtered, washed and mixed uniformly with an aqueous solution of chromic anhydride. The paste is dried at 350‹ C., broken up and reduced in a current of hydrogen at 400‹ C. Over this catalyst crude illuminating gas, together with water vapour, is passed at between 380 to 450‹ C. after the crude gas has been freed from dust and pitchy matter by passage over pumice, bauxite, &c. The gases leaving the reaction vessel are cooled whereupon liquor ammonia, benzene and its nearest homologues cordense.

Abstract: 525,741. Automatic exchange systems. FIDES GES. FUR DIE VERWALTUNG UND VERWERTUNG VON GEWERBLICHEN SCHUTZRECHTEN. Feb. 27, 1939, No. 6473. Convention date, Feb. 26, 1938. [Class 40 (iv)] In an impulse repeater such as that described in Specification 458,095, the pins marking the digits to be transmitted arrest the transmitting member indirectly and are not subjected to stress due to the rotational energy of the transmitting member. At the beginning of an impulse train, a magnet 7 is operated and the armature 9 displaces a sleeve 10 to the right. A lever. 11 is thus withdrawn from the proximity of pins 12, Fig. 2, slidably mounted in two fixed discs 13. Each impulse causes the magnet 5 to move the gear wheel 4 and the associated shaft 3 one step. Meanwhile, the wheel 16 is held and a spring within the housing 17 is wound up. At the end of an impulse train, magnet 7 releases and a restoring spring associated with the lever 11 causes the sleeve 10 to be restored and one of the pins 12 to be displaced to the right. During the impulsing the wheel 16 is held by a lever 35, one end 36 of which engages a cam 37 on the shaft carrying the impulse wheel 24, the wheel 16 being geared to this shaft. The lever 35 is pivoted at 36 and engages the end 32 of another lever 29 pivoted at 30, Fig. 2, on the wheel 16. The end 31 of the lever 29 only engages pins displaced to the right and it rotates anti-clockwise to stop the wheel 16 on engagement. At the end of an impulse train, a magnet 15 between the plates 13 is energized, operating an armature 27 to restore the holding pin 12 marking the last digit transmitted, thereby releasing the levers 29 and 35 and the wheel 16. The wheel 16 rotates, causing the impulse wheel 24 to operate the contacts 25 until the end 31 of the lever 29 engages the pin displaced as described. When the lever 35 is turned to stop the wheel 16, the contacts 33 are closed to mark the end of the train. Off-normal contacts 41, normally closed, are controlled by a flange 39 on a lever 38 pivoted at 30. In the normal position, a pin 42 on the wheel 16 abuts against a projection 44 and engages a lever (not shown) to press the flange 39 against the contacts 41. The lever 35 may be replaced by an electro-magnetic device controlled by the contacts 33.
