Title: Method and extractant for segregating the fat content of fat-containing materials
IPC: C11B1/10
Filed: 1959-03-09
Abstract: A fat-extractant composition comprises by weight 3-6,5 parts of an ester or ether of a polyoxyethylene having a minimum of 5 and an average of 16 oxyethylene groups per molecule with, respectively, an aliphatic or heterocyclic acid having 12-30 carbon atoms per molecule or an aliphatic alcohol having at least 12 carbon atoms in the chain, 1-5,5 parts of ethylenediamine tetraacetic acid or a soluble salt of gluconic acid and 1-5,5 parts of an alkaline alkali metal salt.  The extractant preferably also comprises up to 5,5 parts of urea as an anticoagulant and up to 4 parts of a buffering agent such as disodium orthophosphate.  The preferred alkali metal salt is sodium carbonate and the preferred gluconate is sodium or potassium gluconate.  The extractant may be in granular form or dissolved to form a solution. The extractant may be prepared by grinding and screening individually urea, sodium phosphate, EDTA and sodium carbonate, mixing and stirring in the polyoxyethylene ester component until the product cakes, breaking and screening.  This material may then be restirred, broken and screened and allowed to cure at room temperature.  The cured product dissolves in water, initially as a colloid.  When used in extracting milk, methanol may also be present in the extractant. In order to extract the fat from materials such as milk and cream, meat and meat byproducts, e.g. tankage and meat scraps, soya beans, peanuts, cotton seed and other oils and oil-bearing seeds, processed products such as evaporated or condensed milk, cheese, ice cream, frozen desserts, salad dressings, potato chips and fried corn meal products, the extractant is added in the presence of water and the mixture heated to 100 DEG C. until stratification into fat, surfactant and aqueous medium (in downward sequence) takes place, and then adding water and cooling, e.g. to 55 DEG -60 DEG C., until the strata are rearranged, into the downward sequence fat, aqueous medium and surfactant.  If the added water is cool, the last two steps are accomplished simultaneously, but they may be performed in either order.  The pH is preferably maintained at 7,5-9,5.  In treating milk or cream which has soured it may be desirable to add aqueous citric acid before the extractant.

Title: Method and apparatus for producing ethylbenzene
Inventor: KRAUSSE DAN MARSTON
IPC: C07C7/10
Filed: 1960-03-10
Abstract: Ethylbenzene is separated from a mixture thereof with xylenes by fractional distillation at a reflux ratio of more than 40 : 1 in a distillation column or series of distillation columns having at least 150 distillation plates or stages.  In a typical example a naphthanic feed stock was stabilized to a boiling point range of 69 DEG -149 DEG C., the stock having a 10% boiling point of 82 DEG C., a 50% boiling point of 100 DEG C. and a 90% boiling point of 118 DEG C., the naphthan analyzing 48% paraffins, 42% naphthenes and 10% aromatics. The feed was then passed over platinum at a temperature of 491 DEG C. and a pressure of 29 atmos. with a hydrogen to hydrocarbon molar ratio of 7,5:1, the product, which comprised 45% paraffins, 6% naphthenes and 49% aromatics, was then entracted with diethylene glycol and dipropylene glycol and then the benzene and xylenes removed.  The C8 fraction was then sent to a 3 column still containing 130 plates in each and distilled at a reflux ratio of 87 : 1.  The overhead product consisted of ethylbenzene containing 4,5% toluene, which if removed by further distillation gave ethylbenzene of 99,995% purity.ALSO:In a process for separating ethylbenzene from a mixture thereof with xylenes which comprises fractionally distilling the ethylbenzene at a reflux ratio of more than 40 : 1 in a distillation column or series of distillation columns having at least 150 stages (see Group III), a naphtha feedstock is aromatized by passing over a dehydrogenation catalyst such as one containing platinum at 440 DEG C. to 525 DEG C. and under a pressure of 14-34 atmospheres in the presence of 4-12 moles of hydrogen per mol of hydrocarbon.  In a preferred embodiment, a naphthenic feedstock was stabilized to a boiling range of 69 DEG C.-149 DEG C., the naphtha analyzing 48% paraffins, 42% naphthenes and 10% aromatics.  It was passed to a first reactor of a series of 4 containing platinum deposited on a carrier at a temperature of 491 DEG C. and a pressure of 29 atmospheres with a hydrogen to hydrocarbon molar ratio of 7.5 to 1.  The product was stabilized in a stabilizer as illustrated in Fig. 2 (not shown).  It contains 49% aromatics 45% paraffins and 6% naphthene.

Filed: 1936-03-24
Abstract: 472,602. Land mines. TURNER, B. L. March 24, 1936, No. 8760. [Class 9 (ii)] A land mine of flat form, which can be exploded by means located at a plurality of points around its perimeter, comprises a shallow cylindrical casing 1 containing an explosive charge 3 adapted to be fired by a primary charge 4 arranged at the centre of the casing in the inner end of a radially extending tubular housing 5. The charge 4 is fired by a detonator 6, the centre cap 7 of which is adapted to be struck by a firing pin 8. The detonator can be reversed in the housing 5 so as to render the mine safe during transport. The firing pin 8, which is actuated by a spring 9, is held in the retracted position by a pin 11 which abuts against the outer end of a sleeve 10 and passes through a hole in the outer end of the pin 8 and through a short longitudinal slot in the outer end of the housing 5. A wire 12, which passes around the casing within a tubular guide 13, has. one end anchored at 12a whilst its other end is secured to an eye 11a on the pin 11. The guide 13 is interrupted at intervals so as to accommodate a number of depending arms 14 on a ring or disc-like plate 15 secured to the casing 1 by resilient fingers 18, the arrangement being such that when the ring 15 is depressed by the weight of a vehicle, such as an armoured car or tank, one or more of the arms 14 will tension the wire 12, with the result that the pin 11 is withdrawn and the firing pin 8 released. In order that the mine shall only be actuated by a predetermined minimum weight, means are preferably provided which yieldingly oppose depression of the ring 15. Such means may comprise a V-section metal ring 21 adapted to rest by its edges on the top of the casing or; alternatively, the ring 15 may itself be of L- or inverted-V-section. A safety pin 24 may be passed through the outer end of the pin 8 within the outer end of the housing 5 which is closed by a cap nut 22, one or more washers 23 being gripped between this nut and the periphery of the casing. According to a modification, Fig. 5 (not shown), the wire 12 is accommodated in a circumferential groove formed in the casing 1, this groove being intersected by a number of vertical grooves which receive the depending fingers 14. The mines may be strewn loosely over a large area by being dropped from vehicles or aircraft.
