Abstract: 1,197,812. Vehicle levelling system. AUTOMOTIVE PRODUCTS CO. Ltd. 10 Jan., 1969 [15 Jan., 1968], No. 2112/68. Heading B7D. A vehicle suspension system comprises upper and lower suspension arms 14 and 16 which respectively support a vehicle sprung by means of a vibration damper 35 and a variable length liquid filled strut 18 incorporating an air spring 23 which act between the sprung and unsprung masses of the vehicle, relative movements between these masses being transferred to an inertia mass 42 by a linkage involving arms 16, 34, 32, 39 and a coil spring 48 to an arm 38 supporting the inertia mass causing the latter to pivot to operate a valve 45 controlling the flow of liquid to and from the strut, the movement of the inertia mass being damped by a damper 49. According to the position of the valve spool 45a a chamber 23a in the strut is placed in communication with a source of liquid 27 via a port 56 or a reservoir via a conduit 24 leading from the chamber in which the inertia mass is mounted. A valve 58 is provided to maintain pressure in the strut when the vehicle is standing and the suspension is so arranged that the inertia mass accelerates at the same rate as the sprung mass of the vehicle under dynamic load changes so that the valve 45 does not operate under these changes.

Title: Improvements in distillation installations, solvent recovery plants and similar installations for the recovery of liquids by heat treatment
IPC: B01D3/00
Filed: 1923-01-30
Abstract: 215,073. Hughes & Co., Ltd., F. A., (Schmidt, H.). Jan. 30, 1923. Volatile liquids, recovering; hydrocarbons, distilling.-In distilling a volatile liquid from a liquid absorbent such as is used in removing benzol from coke oven gases or in recovering solvents in the rubber, artificial leather or film industries, regular action of the pumps which convey the liquids is ensured by admitting air, gas or vapour to the suction side of the pump to supply any deficiency in the liquid supply, and the air, gas, or vapour is returned to the suction side after passing through the apparatus. As applied to separating benzol from mineral oil, the liquid, supplied through a pipe a, is forced by a pump b through a pipe d to a washing column e in which benzol is removed from the air passing from the distilling-column p through the conduit r. If the supply of liquid in the conduit a is deficient, air is drawn from a pipe i into the pump, and air is returned from the washing column e through a conduit f and a fan g to the pipe i. The liquid is pumped from the base of the washing-column e by a pump l through a pipe m, heat-interchanger n, and pipe o to the column p which comprises a central heater p<2> and an upper cooler q. Air passes from the top of the column p to the base of the column e by a conduit r. The liquid from the base of the column p is forced by a pump s through the heat-exchanger n and pipe u into a pipe v from which the liquid passes to a tank w, and air is returned by a pipe x to the column p.

The benzene nucleus, in addition to the alkyl groups, may contain halogens, or nitro groups; the aliphatic groups may also be substituted by hydroxyl, aldehyde, keto, or carboxyl groups.  A suitable soluble catalyst is cobalt naphthenate.  An example is given of the process.  The Specification as open to inspection under Sect. 91, comprises the oxidation as above of o-dialiphatic benzenes, i.e. the subject-matter of Specification 673,828.

IPC: C07C45/35
Filed: 1962-01-26
Abstract: a ,b -Unsaturated aldehydes or ketones are prepared by oxidizing an olefin having at least 3 carbon atoms in a gaseous phase in the presence of molecular oxygen, steam and a catalyst comprising a solid thermostable oxygen-containing compound of phosphorus and of at least one of molybdenum, tungsten and vanadium in at least two reaction stages, in such a manner that the gaseous mixture obtained after one reaction stage is introduced into the next reaction stage after the major portion of the carbonyl product has been removed and subsequently a further quantity of steam and oxygen is added so that at the end of the last reaction stage more than 70% of the olefine introduced into the first reaction stage has been converted into a ,b -unsaturated aldehydes or ketones.  The catalyst may also contain as optional constituents oxygen-containing compounds of iron, cobalt, manganese, antimony, bismuth, tellurium, coppers, nickel, cerium, silver or palladium.  Any unused olefin from the final stage may be recycled to an earlier stage.  The catalyst may be of different composition in the different stages and may be supported on conventional materials, e.g. alumina, titanium dioxide, zirconium dioxide, pumice, silicon carbide and, in particular, those containing silicic acid, e.g. kieselguhr and/or silica gel. The olefins used as starting materials may be diluted, for example with methane, ethane, propane, butanes, ethylene, or nitrogen or carbon oxides. The preferred catalyst is one comprising oxides or mixed oxides of molybdenum, bismuth, iron and phosphorus.  The process is preferably carried out at 300-500 DEG  C.  The process may, for example, be used for the conversion of propylene, isobutylene and butylene to acrolein, methacrolein and methylvinyl ketone respectively.ALSO:A catalyst for use in the oxidation of olefines comprises a solid thermostable oxygen-containing compound of phosphorus and of at least one metal selected from molybdenum, tungsten and vanadium.
