Abstract: 138,119. White, A. E., (By-Products Recovery Co.). Jan. 23, 1920. Film evaporators.-Milk &c. is sterilized and concentrated by treatment, after a preliminary heating and partial concentration, in a cylindrical jacketed vessel heated to about 180‹ F. over the surface of which the milk is spread by rotary spring blades. The preliminary heater consists of a trough in which rotate hollow disks through which steam is passed. The blades 26 are perforated and notched as shown, and are pivoted to the ends of rotating arms, their motion about the pivots being limited by stops.

Patent GB-722824-A (GB)
Title: An improved process for the production of aromatic hydrocarbons
IPC: C07C5/333
Filed: 1952-02-04
Abstract: Aromatic hydrocarbons are produced by passing vapours of a normally liquid hydrocarbon feed stock consisting of paraffins or naphthenes having at least 6 carbon atoms in an unbranched chain or in a ring respectively or mixtures thereof, together with a water-free diluent consisting of paraffins containing not more than 4 carbon atoms, the molar ratio of diluent to feed stock being about 0.5-20 : 1, over an aromatizing catalyst under aromatizing conditions.  A by-product gas enriched in hydrogen useful as a fuel or for oxidation to CO + H2 mixtures and, where butanes are present in the diluent, containing n and isobutenes formed by dehydrogenation and isomerization, is also obtained.  The diluent may be natural gas, off-gas from polymerization, alkylation or alcohol processes of C1-C3 with or without some C4 and from which olefins have been removed, or refinery gas having low olefin content.  An n-hexane fraction from naphtha is suitable for benzene production; a heptane and methylcyclohexane fraction for toluene.  Aromatizing catalysts include moblydena or chromia with various carriers and promoters.  Temperature is about 850-1150 DEG  F. and pressure atmospheric or up to 50 p.s.i.  Fixed, moving or fluidized catalyst may be used with regeneration and stripping of adsorbed water and oxygen before recycling.  The reaction products may be fractionated to recover aromatics or an aromatized naphtha, a hydrogen-rich gas, and gaseous hydrocarbons which may be recycled as diluent.  Examples describe the aromatization of n-hexane over a chromia-alumina catalyst using no diluent, various hydrogen ratios, and a 3 : 1 molar ratio of methane; the aromatization under the same conditions of a feed containing n-hexane and cyclohexane together with methyl pentanes and methyl cyclopentane when coking is materially increased; the production of toluene from n-heptane, methyl cyclohexane concentrates with methane or hydrogen or no diluent; and the production of benzene and butenes using a hexane-rich fraction and a 10 : 1 molar ratio of butane or isobutane as diluent.

[Class 12 (i)] A shaft bearing, as for a rotor, is yieldable in different directions to different extents to enable the shaft to pass smoothly through its critical speed, damping means absorbing the vibrations. The shaft 1 rotates in a split bushing 2 horizontally movable in a split housing 3 by bearing on guide blocks 5, 6 having spherical surfaces (not shown) which also permit tilting of the shaft. Secured to the lower part of the bushing 2 are rods 19, 20 terminated by the ends of tubes 21, 22 attached to the housing 3 whereby the bushing may move horizontally within the limits of clearance 4 by virtue of the elasticity of the rods and tubes.

Movement is damped by the friction between the bushing 2 and the supporting block 5, or by means of an oil dashpot (not shown) incorporated in the rods and tubes. The frictional damping means is adjustable by lifting the bushing 2 with respect to the housing 3 by rods 8, 9 bearing on the machine cap 10 and enclosed by rods 12, the lift being measured by an indicator dial (not shown).
