Title: Improvements relating to the control of fuel and air supply to boiler furnaces
IPC: F23N3/02
Filed: 1927-04-22
Abstract: 299,344. Stancliffe, C. W. April 22, 1927. Fluid-actuated valves.-In apparatus for controlling boiler furnaces comprising a controlling member responsive to a boiler condition and a plurality of controlled members each effecting a variation in a supply or maintenance accessory such as air supply, fuel supply or flue damper, means are provided in connection with more than one of the controlled members for varying independently the relation between the controlling and such controlled members at any one part of the range of action of the controlling member irrespective of the relation existing at other parts of the range. As shown the steam pressure acts, through a chamber C containing oil and water, on a plunger A which through relav mechanism moves a main control cable G connected to a number of supplementary control cables such as M, Fig. 2, each arranged to lift or lower by an abutment m a series of weights Q hung from a bracket 0 one below another by chains e and each connected to the supply device, such as a damper P, by separate chains or cables R' - - R<4>. The damper is counterweighted and as the control cable M moves to the left the lowermost weight will be lifted and the chain R<4> will be slacked, allowing the damper to close until the chain R<3> becomes taut, when movement of the damper will cease until the cable M in its continued movement lifts the second weight Q. The damper will then be moved a further step until the chain R<2> becomes taut, and so on. By adjusting the lengths of the chains R' - - R<4> independent variations of the relation at different parts of the range can be obtained. Specifications 147,295, [Class 51 (i), Furnaces and kilns, Combustion apparatus of], and 300,222 are referred to.

Title: 2-semicarbazido-acetic acid and a process for its production
IPC: C07C281/06
Filed: 1954-04-20
Abstract: The invention comprises 2-semicarbazidoacetic acid and its preparation by the gradual addition of an aqueous solution of a monohaloacetic acid to an aqueous solution of sodium hydroxide in hydrazine hydrate at 90-100 DEG  C., removal of water and residual hydrazine hydrate by distillation with an inert high boiling diluent, reaction of the reaction product with a reagent capable of converting a hydrazino group to a semicarbazido group in aqueous solution, addition of an acid stronger than cyanic acid to adjust the pH of the reaction mixture to a value of from 3 to 9, and final adjustment of the pH to the isoelectric point to cause 2-semicarbazidoacetic acid to separate.  A preferred reagent for the second stage is an alkali metal cyanate, and the hydrazine hydrate advantageously has a concentration of 50-85 per cent by weight.  The temperature is preferably maintained at 90-100 DEG  C. for an hour after the halo-acetic acid, e.g. monochloracetic acid, has been added and before the water and residual hydrazine hydrate are removed. Specified diluents for this removal are mineral oil, polypropylene glycols and polyethylene glycols, the second of these being used at 40-50 mm. and 50-60 DEG  C.  Preferably an amount of acid, e.g. concentrated hydrochloric acid, necessary to bring the pH to a value between 6.5 and 7.5 is added and the, after about two hours, additional acid is added to adjust the reaction mixture to its isoelectric point, i.e. 2.4 at 25-30 DEG  C.  An example is given. The new compound is stated to be useful as an intermediate in the preparation of N-(5-nitro-2-furfurylidene)-1-amino hydantoin.ALSO:Water and excess hydrazine hydrate are removed from a reaction mixture obtained by the gradual addition of an aqueous solution of a mono haloacetic acid to an aqueous solution of sodium hydroxide in hydrazine hydrate at 90-100 DEG C., by distillation with an inert high boiling diluent such as mineral oil, polyethylene glycols or polypropylene glycols.  Use of the latter at 40-50 mm. and 50-60 DEG C. is preferred.
