Title: A process for protecting vegetable and animal goods during storage
IPC: A23L3/3427
Filed: 1933-06-06
Abstract: Cabbages and other vegetable substances are preserved by storage in air to which a limited and controlled alkalinity is imparted, preferably having a pH value of 7.5 or over.  A continuous, controlled ventilation may be employed during the storage which may be effected in store houses, barns, transport means &c.  Subsequent treatment of the substances to remove the alkaline material is not necessary.  In an example, cabbage is stored in a chamber in which ammonium carbonate is disposed at a number of places, e.g. in tablet &c. form in or near the air admission openings.  Alternatively, combustible porous bodies of determined size, such as coke from coal, wood, peat or the like, are impregnated with a material yielding a gaseous alkali and are burned to liberate the alkali.  The heat liberated by burning a previously dried briquette may be used for drying a freshly impregnated briquette.  The briquette may be of such dimensions that it is completely burnt in a predetermined time, say 24 hours. The alkalization may also be effected by liberating ammonia gas from a bottle of liquefied ammonia.  Easily volatile amines such as ethyl- or methylamine, or di- or polyalkylamines of similar odour may also be used, and, in liquid state or in aqueous or alcoholic solution, may be introduced into the storage atmosphere by evaporation, spraying &c.  Automatic electrically-operated means may be provided for constantly controlling the alkalinity of the air.ALSO:Animal and vegetable substances are preserved by storage in air to which a limited and controlled alkalinity is imparted, preferably Ph 7.5 or over.

Title: Improvements relating to apparatus for testing the balance of machinery having rotating parts
IPC: G01M1/22
Filed: 1923-06-25
Abstract: 222,195. Elverson, A. J. H., and Kennedy & Co., Ltd., H. June 25, 1923. Testing balance of rotary apparatus.-Comprises a method and apparatus involving the use of a stroboscope. The machine A, for instance a motor car engine, is mounted in a frame B in a manner similar to that in which it is mounted in the car frame, the frame B being pivoted at d to a bed plate C between which and the frame is a spring D. The shaft E of the machine drives a parallel shaft F through the medium of a toothed wheel E<1> and a long pinion F' helically splined to the shaft F. This shaft drives a parallel shaft G, upon which is an adjustable out-of-balance mass system H. The system H comprises unequal weights carried by pairs of links of different lengths so that in one position they are balanced. With the system H adjusted in this position, the machine is run up to the critical speed, and the vibrations are viewed by the following means. A stroboscopic flash-timing apparatus s is mounted on the shaft E, and electric leads T', T<2> taken off to a lamp L, an index on which, for instance a cross, is thus illuminated synchronously or nearly so with the machine. An image of this index in the mirror M is viewed through the telescope T provided with a reticulate'd cross-bar system. The masses are then adjusted radially by moving the collar h, and the phase adjusted by sliding the wheel F<1> to bring the vibrations to a minimum. The system H is then moved axially along the shaft G until the position of minimum vibration is reached. From the adjustments made a measure of the degree of lack of balance of the machine can be found. Sometimes the vibrations are due to harmonics caused by out-ofbalance masses on secondary shafts. These may be investigated by driving the disturbing system at the requisite multiple or fraction of the speed of the main shaft, the time flashes being correspondingly adjusted.

Patent GB-869115-A (GB)
Title: Polymerising alkylene oxide
IPC: C08G65/26
Filed: 1957-05-28
Abstract: Alkylene oxides are polymerized in presence of catalysts which are alkaline earth metal derivatives of mono- or polyhydroxy compounds which have been treated with CO2 and water until their weight had increased by not more than 70%.  Suitable catalysts are alkaline earth metal salts of primary, secondary or tertiary alcohols, glycols, phenols, naphthols or halogenated phenols, glycerol, dextrose or pentaerythritol; also of hydroxy amines, e.g. ethanolamine, aminophenol, p-benzylaminophenol p-actyl-aminophenol. Alkylene oxides polymerized are ethylene, propylene, styrene, or 1, 2- or 2, 3-epoxy butane.  In the example propylene oxide was polymerized in presence of the calcium derivative of ethylene glycol which had been exposed to the carbon dioxide and water in moist air until its weight had increased by 60%.  The polymer was a stiff, tacky semi-solid from which a crystalline polymer could be obtained by extraction with chilled acetone and preciptation.  The products generally are watersoluble solids with reduced viscosities greater than 1. They are useful as thickeners, sizes, binders, lubricants and for making shaped articles.  The catalyst remaining in the polymer is present in small amount which is beneficial in many applications. Specifications 869,112, 869,113, 869,114 and 869,116 are referred to.ALSO:Catalysts for the polymerization of alkylene oxides are produced by the reaction of an alkaline earth metal derivative of an organic mono- or poly-hydroxy compound with carbon dioxide and water until the weight has increased by an amount not greater than 70%. Suitable hydroxy compounds are methanol, ethanol, propanol, butanol, lauryl alcohol, ethylene glycol mono ethyl ether, cyclohexanol, ethylene-, propylene- or butyleneglycol, decamethylene glycol, b -thiodiglycol, phenol, xylenol, cresol, resorcinol, naphthol, m-chlorophenol, glycerol, dextrose, pentacrythritol, ethanolamine, aminophenol, and p-benzyl or -acetyl-aminophenol.  Derivatives of lower alcohols, e.g. strontium methylate, need less exposure to carbon dioxide and water to produce the optimum weight increase (ca. 60%) than do derivatives of higher alcohols, e.g. butanol, or of glycols. Treatment of the derivatives may be effected by exposure to water vapour and carbon dioxide, or by pouring the dissolved or suspended derivative into an aqueous organic liquid in presence of carbon dioxide, or by grinding the derivative in a mortar in the presence of moist air.  Hydroxy compound liberated by the treatment may be removed, e.g. by mild heating under reduced pressure, with a further increase in catalytic activity.  In the example a solution of ethylene glycol in liquid ammonia is added to a solution of calcium in liquid ammonia, and the mixture is allowed to stand for 1 hour exposed to the carbon dioxide and water in moist air.  The ammonia is evaporated and the product sieved.  Specifications 869,112, 869,113, 869,114 and 869,116 are referred to.
