Title: Pyridine-(3)-sulphinic acid, sulphones related thereto, salts thereof and a process for the manufacture of same
Filed: 1955-07-06
Abstract: The invention comprises compounds of the formula <FORM:0773261/IV(b)/1> wherein n is 0, 1 or 2 and R is hydrogen or a substituted phenyl or pyridyl radical when n= 0, or is a phenyl or pyridyl radical or a substitured phenyl or pyridyl radical when n=1 or 2, and salts of these compounds such as the acid addition and quaternary salts, and alkali-metal salts of the sulphinic acid (n=0, R=H), the substituents being halogeno, alkyl, cyano, alkoxy, acyloxy, hydroxy, nitro, acylamino or nitro radicals.  The compounds are made by condensing pyridyl-3-sulphonyl chloride with hydrazine, reacting the resulting pyridine-(3)-sulphonic acid hydrazide with a carbonyl compound containing three or more carbon atoms and, if sulphones are required, either condensing the resulting pyridine-(3)-sulphinic acid (in the form of a salt thereof) with a substituted phenyl or pyridyl halide or a nuclear substituted or unsubstituted phenyl - methyl, phenyl - ethyl, pyridyl-methyl or pyridyl-ethyl halide in an organic solvent, or reacting it with the appropriate benzene or pyridine compound containing a double bond adjacent to the phenyl or pyridyl group preferably in a liquid reaction medium such as water or an organic solvent or mixtures thereof, and, if desired, converting any nitro or acylamino substituent present in the product into an amino group by hydrogenation or hydrolysis or any alkoxy or acyloxy group present into a hydroxy group, by hydrolysis, and, if desired, converting the product into a salt.  Salts of pyridine-(3)-sulphinic acid are made by neutralizing the acid with the appropriate alkali. Acid addition salts and quaternary salts of the sulphones are made by treatment with the appropriate strong acid or quaternizing agent, suitable quaternizing agents being lower-alkyl halides, alkenyl halides, aryl halides containing an activated halogen such as 1 - chloro - 4 - nitro - benzene, aralkyl halides and phenacyl halides. The amino phenyl sulphones may be produced by reduction of the corresponding nitro-compounds with Raney nickel and hydrogen. Quaternary salts of the amino-phenyl sulphones are made by acetylation of the amino group followed by quaternization and deacylation.  Examples describe the preparation by the above methods of pyridine-(3)-sulphinic acid, the corresponding sulphones C4H5N.SO2R1, wherein R1 is 4-nitro-phenyl, pyridyl-(4), nitrobenzyl, p-aminobenzyl, p-acetaminobenzyl, m-nitrobenzyl, p-nitrophenethyl, p-chlorobenzyl, pyridyl-4-methyl, pyridyl-(4)-ethyl and pyridyl-(2)-ethyl and of acid addition and quaternary salts of the sulphones such as the hydrochloride, methyl bromide, propyl bromide, butyl bromide, allyl chloride, benzyl bromide and p-nitrobenzyl bromide.

Title: Improvements relating to farrowing crates for sows
Inventor: HODGKINSON NORMAN
IPC: A01K1/02
Filed: 1958-06-19
Abstract: 932,189. Farrowing crates. N. HODGKINSON. Sept. 21, 1959 [June 19, 1958], No. 19583/58. Class 5(2). A farrowing crate for sows, designed to protect piglets from being crushed by the sow, comprises a central compartment 1 in which the sow is confined, and nesting units 3 for piglets along the sides of the central compartment, the nesting units being raised or lowered relative to the central compartment in response to movement of the sow, whereby the piglets are raised to a position 5 in which they can suckle the sow when she lies down, and are lowered to a position 4 away from the sow as she stands up. The central compartment 1 of the crate comprises a floor 1a, sides 1c, an entry door 2 hinged at one end of the compartment, and an exit door 15 hinged at the other, the latter being adjustable to accommodate sows of different sizes. The doors and sides of the central compartment are spaced above the floor, the gap between the door 2 and the floor being for the delivery of the piglets, as they are born, on to the resilient floor of a detachable nesting section 3a at the rear of the compartment. The section 3a is put in position after the door 2 has been closed on the sow, and is in communication with the sections 3. The gap below the side walls allows the piglets to gain access to the sow for suckling and that below the door 15 accommodates a feeding trough 17. Movement of the nest boxes 3, which are counterbalanced by weights 3b, together with the detachable unit 3a, is initiated by the sow's clearing or obstructing a beam of light 6 passing through slots in the side walls between photo-electric cells 7 whose height above the floor 1a may be adjusted. The clearing or obstructing of the beam operates a reversing motor 8 which in turn rotates a screw 9 causing the sides 10 to move to either raise or lower the nesting units 3, 3a by mechanical means such as nylon wires 19 running over pulleys 11. Movement of the rider is restricted by switches L1 and L2 which operate to open the electric circuit to the motor when contacted by the rider, and at any point in its travel between the limits, the clearing or obstructing of the beam by the sow will reverse the travel of the rider and of the nest units. As a safety measure, a handle fitted to the motor 8 enables the nests to be lowered mechanically in the event of failure of the electrical equipment, an alarm being fitted to indicate such failure. The lifting mechanism may either be a fixed part of a crate, or may be mobile so as to serve a number of crates. Heating lamps 3c are provided on the nesting units, together with means of adequate ventilation and for draining liquid away from the units.

Patent GB-779703-A (GB)
Title: Pyrazolone compounds and a process for making them
Filed: 1954-07-06
Abstract: The invention comprises pyrazolones of the formula: <FORM:0779703/IV(b)/1> where R is benzyl or nuclear-substituted benzyl, R1 is hydrogen or C1-C4 alkyl and R2 and R3 are C1-C4 alkyl or aralkyl.  These are prepared from the corresponding pyrazolones without the 4-substituent by treatment with nitrous acid to introduce a 4-nitroso group, reduction to 4-amino and reaction with an aliphatic or aromatic aldehyde in the presence of a reducing agent. Reduction of the nitroso group may be effected by zinc and acid, hydrogen and a Group 8 catalyst, or sodium bisulphite; the latter gives a sulphamic acid which is subsequently hydrolysed.  The groups R2 and R3 may be introduced successively with two different aldehydes or simultaneously with two mols. of the same aldehyde. The reducing agent for this step may be formic acid, zinc and acid, or hydrogen and a catalyst.  The two reduction steps may be carried out in one process the aldehyde being added at the beginning.  Instead of the 4-nitroso group there may be used compounds containing a 4-nitro-, 4-halo, 4-alkylideneamino or 4-aralkylideneamino substituent. Examples show the preparation of products and intermediates where R is benzyl, p-methylbenzyl or o-methoxybenzyl, R1 is methyl or n-propyl and R2, R3 are dimethyl, diethyl, methylisobutyl or methyl-benzyl. In general the benzyl group may be substituted by halogen, lower alkyl or lower alkoxy.  1-Benzyl - 2 - methyl - 3 - n - propyl - 5 - pyrazolone is obtained by heating benzylhydrazine with ethyl butyrylacetate and alkylating the product with methyl iodide. 1-(o-Methoxybenzyl)-2 : 3 - dimethyl - 5 - pyrazolone is obtained similarly.
