Title: Improvements relating to alternating current motors with short-circuited armatures
IPC: H02K17/16
Filed: 1928-06-07
Abstract: 292,071. Bergmann Elektricitõts- Werke Akt.-Ges. June 11, 1927, [Convention date]. Alternating current motors.-In a squirrel cage induction motor, the desired relation between starting torque and starting current is obtained by so designing the machine that its shortcircuit impedance is kept low, by reducing its inductance without substantially altering its total ohmic resistance. This is done by winding the rotor bars a, Fig. 1, in flat slots and by uniting them by end rings b, Fig. 2, of cylindrical form. These rings are placed as near as possible to the stator overhanging coil-ends, which are of similar cylindrical form. The inductance of the stator winding may be reduced by making it a two-layer winding with shortened pitch. The rotor is also preferably given an increased and the stator a reduced ohmic resistance such as to keep the total resistance of the machine unchanged' compared with normal values.

Title: Preparation of semicarbazones
Inventor: ARGYLE CHRISTOPHER STANLEY
IPC: C07D307/76
Filed: 1955-06-16
Abstract: Semicarbazones are obtained by reacting aldehydes or ketones with the reaction product of hydrazine or its functional derivatives or salts and nitrourea.  The various components of the reaction may be added in any order.  If desired a salt of hydrazine and nitrourea may first be prepared by the reaction of aqueous hydrazine hydrate and nitrourea, the salt being precipitated from the solution by the addition of alcohol or other organic liquid.  The reaction between hydrazine and nitrourea with formation of semi-carbazide, is effected in aqueous solution, preferably at elevated temperature.  Instead of hydrazine itself, hydrazine hydrate, sulphate, hydrochloride or acetate may be used.  The formation of semi-carbazones may take place at a pH of 2-11, preferably in the presence of acetic acid. A solid mixture of nitrourea with a solid hydrazine derivative such as hydrazine sulphate may be prepared and used directly as the reagent for the production of semi-carbazones.  The carbonyl compound may be formed in situ in the reaction mixture, e.g. 5-nitrofurfurylidene diacetate may be hydrolysed in the reaction mixture and the 5-nitrofurfuraldehyde thus formed is reacted with the reaction product of hydrazine and nitro-urea.  The process may be used for the production of semicarbazones of sex hormones. In examples: (1) nitrourea is reacted with hydrazine hydrate in aqueous solution at 60-65 DEG  C., and after subsequent cooling to 20 DEG  C., acetic acid and benzaldehyde are added and benzaldehyde semicarbazone is precipitated from the solution; (2) 5-nitrofurfurylidene is hydrolysed with sulphuric acid and after dilution with water, nitrourea and hydrazine hydrate are added and the semi-carbazone produced is precipitated; (3) nitrourea is dissolved in aqueous hydrazine hydrate solution and alcohol is added to precipitate a crystalline salt.  The salt is dissolved in water and heated to 60 DEG  C. to form semicarbazide.  Acetic acid and benzaldehyde are then added to the solution so as to form benzaldehyde semi-carbazone.

Title: Process for the manufacture of pyridoxal-5-phosphoric acid ester and salts thereof
Filed: 1952-07-09
Abstract: Pyridoxal-51-phosphoric acid ester and salts thereof having codecarboxylase activity are prepared by reacting pyridoxal with an aldehyde-protecting substance, e.g. hydrazine, semicarbazides or hydroxyl-amine, treating with metaphosphoric acid and hydrolysing the product to remove the protecting group p  and two of the three phosphorus atoms per molecule in the form of orthophosphoric acid and, if desired, converting the ester thus formed into a salt thereof, e.g. its calcium, magnesium or barium salt.  Specified aldehyde-protecting compounds are N,N-dimethyl-glycyl hydrazine hydrochloride and benzoyl hydrazine which form pyridoxal-41-N, N-dimethyl-glycyl-hydrazone hydrochloride and pyridoxal-41-benzoylhydrazone respectively.  Treatment with metaphosphoric acid yields pyridoxal-41-N,N-dimethyl - glycyl - hydrazone - 51 - triphosphoric acid ester and pyridoxal-41-benzoyl-hydrazone51-triphosphoric acid ester respectively.  Hydrolysis is effected by an acid, e.g. hydrochloric acid, and the mixture obtained is preferably treated with nitrous acid or silver nitrite to decompose the hydrazine, semicarbazide or hydroxylamine.

Metal-heating furnaces; charging and discharging; hearths.-In a continuous metal-heating furnace the hearth or floor is formed with spaced supports 26 for the articles to be heated, and between the supports is arranged a step-by-step conveyer device, which can be raised above the tops of the supports to lift the articles thierefrom, moved longitudinally, and then lowered to deposit them. In the construction shown the conveyer device consists of water-cooled bars 28 extending through the furnace and projecting from the ends thereof a distance equal to the stroke of the apparatus. The bars have vertical portions 29 passing through a supporting table 30, which is mounted on the pistons 49a of airpressure cylinders 48 carried by a reciprocating truck 32, and in operation from the position shown the bars are first lifted vertically, then moved horizontally to carry the articles, such as plates, forward, then lowered to deposit the plates and finally returned to initial position. Water is supplied to the bars through the connection 34 and is discharged at the opposite, end into the pit in which the truck operates. The supports 26 are preferably grouped to correspond with the different positions taken by the articles in their movement through the furnace, and they may either be formed in one with the hearth or may be adjustable thereon. The heating burners are arranged to deliver transversely across the furnace, and the spaced arrangement of the supports 26 allows free play of the gases beneath the articles.
