Title: Method of producing nitrogenous condensation products from acetylene and ammonia
IPC: C07D213/12
Filed: 1952-07-04
Abstract: Nitrogenous condensation products are obtained by passing a mixture of acetylene and ammonia at temperatures of about 350-400 DEG  C. over a catalyst containing U3O8, the temperature at least at the beginning of the operation being about 350 DEG  C.  The product contains in particular pyridine, pyrrole, aliphatic and cyclic amines and nitriles, e.g. aceto-nitrile and a specified product has a B.R. of 50-220 DEG  C. and comprises 13 per cent of diethylamine and propylamine, 44.65 per cent of butylamine and aceto-nitrile, 2.67 per cent of triethylamine and amylamine, 11.65 per cent of pyridine and pyrrole and 22 per cent of homologues of pyridine and pyrrole.  The products may be used as fuel for rocket propulsion.  The catalyst is preferably supported e.g. on alumina and/or infusorial earth.  The catalyst is preferably made from uranium nitrate to avoid the presence of elements which poison the catalyst.  The catalyst may be regenerated by oxidation with e.g. air.  A diagram of suitable apparatus is provided.ALSO:Liquid fuels for rockets are made by passing acetylene and ammonia at temperatures of about 350-400 DEG C. over a catalyst containing U3O8, the temperature at least at the beginning of the operation being about 350 DEG  C.

Filed: 1944-09-12
Abstract: 610,013. Ignition systems. BRITISH THOMSON-HOUSTON CO., Ltd., WELCH, D. F., and COE, R. T. Sept. 12, 1944, No. 17406. [Class 7 (iv)] In a high-frequency ignition system having a low-tension source such as a magneto or ignition coil which charges a condenser which is then discharged through a series spark-gap or gaps and the primary of a 'high-frequency transformer the secondary of which is connected to the sparking plugs and in which the discharge of the condenser through the spark-gap or gaps is initiated in response to current flow in the condenser charging circuit by means of a peaking transformer or peaking choke the peaking transformer or choke has two energizing windings so proportioned and arranged that the effect on its core of the higher frequency current in the secondary of the lowtension source in one winding is neutralised by the effect of the higher frequency current in the primary of the source in the other winding. The object is to prevent premature discharge of the condenser even if the ratio of the frequencies of the higher and lower frequency components of current in the condenser charging circuit is higher than that referred to in Specification 610,012. This avoids difficulties due to uncertain action of the contact breaker sometimes experienced with a low-tension source having the ratio between those frequencies of the order referred to in the previously mentioned Specification. Preferably the ratio of the frequencies is 7 : 1, 11 : 1, 15 : 1, &c. Fig. 1 shows one arrangement in which a magneto having a primary winding 2 and secondary winding 3 charges a condenser 4 which is discharged through series spark gaps 5 and the primary 6 of a highfrequency transformer. Discharge of the condenser is initiated by the peaking transformer 10, 11, 12. The peaking transformer has two energizing windings, one 10 connected in the secondary circuit of the magneto and the other 12 in the primary circuit. The secondary winding 11 is connected to a point between the spark-gaps. The windings on the transformer are so chosen that the effect of the higher frequency current in the secondary is neutralised by the effect of the higher frequency current in the primary. The resulting current in the secondary of the peaking transformer passes through zero only at the point of maximum secondary voltage and premature breakdown of the spark-gaps is avoided. An arrangement is shown in which there is a separate low-tension impulse generator and transformer in the charging circuit and the winding 12 is connected between the contact breaker and one end of the primary of this transformer. Specifications 529,558 and 598,053 also are referred to.

[Classes 2 (ii) and 15 (i)] [See also Group XIII] A process for the wet treatment and drying of freshly spun artificial silk in a continuous operation comprises guiding the threads in helical turns over a rotating cylinder or simultaneously over a group of adjacent coacting rotating cylinders, subjecting them to the known wet treatment processes at the commencement zone of the cylinder or group of cylinders, and drying them in a further zone of the cylinder or group of cylinders, the drying being effected by causing a high-temperature heating medium to act directly upon those parts of the cylinders in the drying zone upon which the turns of artificial silk do not rest or are not resting at the time of such action. The heating medium, e.g. high-temperature combustion gas, may be caused to act either internally or externally upon the cylinder. In the former case the drying zone of the cylinder preferably consists of a conducting fire-proof material such as nickel or steel, and in the latter case it preferably consists of non-conducting fire-proof material such as earthenware or porcelain. The apparatus of Fig. 1 comprises a pair of inclined cylinders 1 and 2 around which the filaments pass in helical turns. The upper cylinder is provided at one end and on the side nearest the lower cylinder with a gas burner 5, and the lower cylinder is provided at the opposite end with spraying pipes 3 and 4. The upper cylinder preferably consists of porous porcelain. In the apparatus of Figs. 3 and 4 (not shown) the heating means comprise surface burners which are applied to both cylinders.
