Filed: 1935-06-12
Abstract: 462,745. Fluid - pressure brakes. WEIHE, (nÚe. LOBINGER), H. June 12, 1935, No. 16968. Void. Convention date, June 12, 1934. [Class 103 (i)] In a hydraulic hand-brake in which a piston 14 in a pressure-producing cylinder 1 is moved by a screw-threaded spindle 19, the pressure in the pipes 7 leading to the brake-cylinders is maintained by means of a spring 21 which also transmits the motion of the spindle to the piston. One end of the spring, which is close coiled and normally is nearly solid, engages the closed end of the piston 14, whilst the other end of the spring is seated in a cup 22 bearing on the spindle 19 operated by a knob 20. A spindle 23 attached to the piston 14 passes through the spindle 19 and normally projects beyond the surface of the knob 20. When the pressure in the pipe system falls below normal, for example on account of loss of liquid or change of temperature, the spring 21 expands to restore the pressure deficiency in the pipe 7, whilst the inward movement of the spindle 23 provides a visible indication of the changed condition of the pressure-producing system.

Abstract: 1,255,554. Recovering aromatics. AIR PRODUCTS & CHEMICALS Inc. 2 April, 1969 [6 May, 1968], No. 17197/69. Heading C5E. Aromatic hydrocarbons are recovered from coke oven light oils containing at least 10% by volume of primary light oil (including naphthalene and other bicyclic compounds) by the following steps: (a) contacting the oil with hydrogen and a recycled heavier oil fraction (see step (d) below) in an upflow hydrogenation reactor operating under substantially liquid phase conditions and containing a hydrogenation catalyst, e.g. sulphided cobalt molybdate/ alumina; (b) subjecting the effluent from (a) to gas-liquid separation; (c) fractionating the liquid from (b) to obtain a vapour overhead fraction (comprising mainly monocyclics) and a heavier oil fraction (comprising bicyclics and higher); (d) recycling at least part of said heavier oil fraction to step (a), the volume ratio of heavier oil to fresh feed being in excess of 1 : 1; (e) hydrodealkylating the overhead fraction from (c) in the presence of a dealkylation catalyst, e.g. chromia/alumina; and (f) recovering aromatics from the dealkylation effluent. Step (a), which serves mainly to selectively hydrogenate polymerizable unsaturates, and uses excess hydrogen, may be operated either under severe conditions, e.g. 285-370‹ C., in which case there is also some hydrogenation of the bicyclic compounds present, or under mild conditions, e.g. 250-285‹ C., in which case the heavy oil fraction from step (c) may be further fractionated to produce a naphthalene heart cut before recycling of the remainder to step (a). Flow diagrams show both alternatives. The gas-phase separated in step (b) may be used to provide part of the hydrogen for step (e). Step (e) may also result in removal of sulphur compounds and non-aromatics by hydrocracking. In Example 1, benzene is the main product, toluene also being obtained. In Example 2, the products are naphthalene and a BTX fraction.

Title: A process for the manufacture of oxygenated organic compounds by controlled oxidation
IPC: C07B35/04
Filed: 1947-06-30
Abstract: <PICT:0636754/IV (b)/1> In the manufacture of oxygenated organic compounds by the controlled oxidation of organic compounds in the presence of hydrogen bromide, wherein the organic compound in gaseous or vaporous form is passed into a reaction zone in the presence of an oxygen-containing gas and hydrogen bromide, a liquid vaporizable under the reaction conditions is injected into said zone whereby said liquid is vaporized and removes heat from the reaction zone. The injected liquid may be a reactant or inert.  Water and a hydrocarbon not reacting under the conditions employed are examples of the latter.  Most effectively the liquid evaporates almost immediately and the jet for spraying the liquid into the reactor may be covered with a mesh to assist this.  In a diagram is shown a device for the oxidation of isobutane to ditertiary butyl peroxide and tertiary butyl hydroperoxide.  Isobutane from pump 3 divides into two streams, one of which is vaporized, mixed with oxygen and hydrogen bromide and after heating to the reaction temperature is passed into reactor 11. The other stream passes through a valve 14 to jets 15 and into the reactor.  The valve may be operated manually or by a temperature-controlling device linked with a thermocouple placed in the reaction zone.  Carboxylic acids, ketones, alcohols, organic peroxides and/or organic hydroperoxides may be prepared using the process.  As starting materials may be used any aliphatic, aromatic, alkylated aromatic and alicyclic hydrocarbons and derivatives thereof such as partial halosubstitution products, nitriles, ketones, alcohols and acids which contain at least one replaceable hydrogen atom.  The preferred class of organic compounds which may be used comprises the saturated aliphatic hydrocarbons containing at least one tertiary carbon atom of aliphatic character or their derivatives optionally unsubstituted or substituted on the primary or secondary carbon atoms with halogen or with aryl or aralkyl substitution of the aliphatic radicles attached to the tertiary carbon atom.  From the large number of compounds mentioned representative of the former class are ethane, n-pentane, cyclobutane, methylcyclohexane, naphthalene, toluene, xylenes, cumene, ethyl chloride, monochlorocyclopentane, benzyl chloride, and of the latter class 3 - methylpentane - 2,3 - dimethylbutane, 1-halo-2-methylpropane, 1-phenyl-2-methylpropane.  Specifications 576,229, 576,255, 577,841, 578,608, 597,029 and U.S.A. Specification 2,373,240 are referred to. The Specification as open to inspection under Sect. 91 comprises also the application of the process to reactions conducted in the two-phase liquid-vapour system.  This subject-matter does not appear in the Specification as accepted.
