Patent GB-606564-A (GB)
Title: Process for the production of a new hexanetriol
IPC: A61Q19/00
Filed: 1945-06-26
Abstract: 1 : 2 : 6-Hexane-triol is prepared by subjecting 2 : 6-epoxy-5-hexenal-1 to the following series of treatment steps: catalytic hydrogenation to saturate the ethylenic linkage and simultaneously or separately, reduction to convert the aldehydic group into a primary alcoholic group and fission of the pyran ring by a method known to be capable of splitting the pyran ring between the oxygen atom and an adjacent carbon atom, these steps being effected in any sequence and being followed, where the method of fission results in an ester, by hydrolysis of the ester groups.  Thus, the epoxyhexenal may be completely hydrogenated to epoxyhexanol and the pyran nucleus thereof opened by the action of an acyl halide or organic acid anhydride, if desired in the presence of an acylation catalyst such as zinc, zinc dust or aluminium chloride and the resulting ester converted to the desired triol by alcoholysis or saponification.  Again, epoxyhexenal may be converted to epoxyhexenol, by reaction in absolute alcohol with aluminium ethylate, which is then treated with acetic anhydride and acetic acid yielding first, epoxyhexenol acetate and then the 1 : 2-diacetate of 5-hexene-1 : 2 : 6-triol (the end form of 5 : 6-hexanediol-1-al, the name used in the Specification as open to inspection under Sect. 91), which is catalytically hydrogenated to yield the diacetate of hexane-triol-1 : 2 : 6, hydrolysis of this ester giving the free triol.  Alternatively, the epoxyhexenol is hydrolyzed with water in neutral or slightly acid or alkaline medium and the resulting 5 : 6-hexanediol-1-al catalytically hydrogenated.  A further method comprises hydrolyzing the epoxyhexenal itself, probably to yield hexanol-2-diol, and then catalytically hydrogenating the reaction mixture.  In Examples: (1) 2 : 6-epoxyhexenal-1, in a mixture of alcohol and benzene, is hydrogenated in the presence of Raney nickel and the resulting epoxy-hexanol refluxed with acetic anhydride and zinc chloride to yield 2 : 6-epoxyhexanol-1 acetate which is isolated and then itself refluxed with acetic anhydride and zinc chloride and the hexane-triol triacetate thus obtained is alcoholysed to the triol by means of methanol; (2) epoxy-hexenal is reacted with aluminium ethoxide in ethanol, the resulting epoxyhexenol is isolated and subjected to ring opening by heating with water and the resulting solution then hydrogenated in presence of nickel to yield the required triol; (3) epoxyhexanol is subjected to ring opening by heating with water and the triol obtained by hydrogenation of the solution in presence of nickel. The triol is stated to be a new compound having many specified industrial applications.

Title: An improved method of and apparatus for balancing out rotating bodies
IPC: G01M1/04
Filed: 1925-06-25
Abstract: 258,667. Blaess, V. June 25, 1925. Testing balance of rotary apparatus. - Comprises a method based upon the fact that the characteristic vibration of any point of the system remains unaltered when the forces exerted by the masses applied in two balancing planes bear the same proportion, as to amount and angular relationship with each other and with the axis of revolution, as the disturbing system of forces. In one way of carrying out the method, Fig. 1, the centre k of a bearing b is steadied horizontally by introducing a force g by adding a mass in the balancing plane d. By adding another mass in the plane d, a perturbative force h is introduced giving the point k its horizontal component again. Experiments are now made in the second balancing plane c to find a force e which will again bring the point k to rest. The proportion of the unknown perturbative forces will be in the proportion of the forces e, h. If now, for instance, the centre i of the second bearing a is stilled by working in the two balancing planes while maintaining the proportion of the forces, the rotor will be completely balanced. In another way of carrying out the invention, a component of the oscillation of any point of the svstem is determined as a function of the number of revolutions and a graph plotted. Two chosen forces are then introduced in the two balancing planes and the same component of the same point is again plotted as a function of the revolutions. The intersecting point of the two curves will give the " characteristic number of revolutions " for which the similar components of two kinds of oscillation are equal. If now one point, say the middle point of one bearing, is stilled by balancing in any balancing plane and then a second point, say the middle of the second bearing and with an optional number of revolutions and the chosen proportion of forces, any component is eliminated by balancing, the rotor is completely balanced. The mathematical relationship is stated between the perturbative forces, the specific replacing forces acting at the bearings, the angular velocity of the rotor, its moment of inertia, mass, distance of the centre of gravity from the centre of the bearings and the distances of the balancing planes from the centre of gravity. By " specific replacing force " is meant the force with which a resilient body tends to return to normal position when displaced through a distance equal to one unit of length. Specified particular cases are also given, amongst which is the case in which the replacing force at one bearing is very small, the bearing for instance being mounted on rollers. In this case, if the other bearing is rendered stationary, the remaining disturbing force passes through the centre of impact of the body oscillating about the fixed bearing and the body is balanced by means of the force ratio which in this case is known. The casings of rotors &c. are provided on the outside with spaces so that compensating masses may be added to the rotating parts.

Patent GB-757498-A (GB)
Title: Improvements in or relating to compositions for stimulating plant growth
IPC: H01H63/06
Filed: 1953-06-16
Abstract: A composition for stimulating plant growth comprises an antibiotic and a diluent inert to the antibiotic, in which composition the concentration of antibiotic is not more than 25 parts per million. The antibiotics referred to are oxytetracycline, thiolutin, penicillin, streptomycin, bacitracin, rimocidin and aureomycin; they may be used in the form of partially purified concentrates, salts such as hydrochlorides and sulphates, alkali metal salts, or complexes, e.g. the crude precipitate recovered from an oxytetracycline fermentation broth on adding certain quaternary ammonium salts.  The diluent is conveniently water, solutions containing 0.5 to 10 parts per million of the antibiotic being preferred.  Germination of seeds may be speeded by surrounding the seeds with a water-disintegrable composition containing the antibiotic in such amount that when the seed is planted and watered it comes into contact with a solution of the antibiotic having a concentration of not more than 25 parts per million.  According to an example concerned with sowing seeds of sorrel (Rumex acetosa) on greenhouse flats of soil, watering tests flats with tap water containing 5 p.p.m. of oxytetracycline and watering control flats with ordinary tap water, there was accelerated germination, and then greater leaf formation and plant height increase, for the test flats; according to an example concerned with sowing seeds of sweet corn (Zea saccharata) in greenhouse flats of soil, watering test flats with tap water containing 5 p.p.m. of oxytetracycline hydrochloride and watering control flats with ordinary tap water, there were, after 4 weeks, increases in the number of germinations, plant height and tissue dry weight for the test flats.  According to an example concerned with placing single seeds of sweet corn in gelatine capsules, filling the remaining capsule space with talc containing 10 p.p.m. of oxytetracycline hydrochloride for one group of seeds, and with talc alone for another group of seeds, placing a number of encapsulated seeds from each group in greenhouse flats of soil, and watering the flats, the proportion of seeds which had germinated after 5 days, and also after 8 days, was greater for the group having the antibiotic in the capsule.
