Reactive esters of compounds II are prepared by reacting compounds VI with reactive diesters of alkanediols, preferably those having two different acid components (e.g. a -bromo-b -or o -chloroalkanes, or arylsulphonic esters of chloro- or bromo-alkanols). N - Piperazinoalkyliminodibenzyls of the general formula IV are prepared by reacting the reactive esters of compounds II with N-acylpiperazines and then hydrolytically splitting off the acyl radical. Acid chlorides of the general formula VIII are prepared by reacting compounds VI with phosgene.

Title: Process and apparatus for producing hydroxyethylcellulose
IPC: B01L3/00
Filed: 1960-02-06
Abstract: <PICT:0925900/IV(a)/1> Hydroxyethyl cellulose is produced by continuously passing a bed of loose, bulky particulate alkali cellulose fibres through a chamber containing ethylene oxide gas, supporting the bed on a vibratory conveyer which subjects the bed to a succession of vibratory impulses, so that the bed alternately rises up from the conveyer and falls back on to the conveyer many times in its passage through the chamber thereby causing the gas to penetrate the bed and react uniformly with the fibres producing hydroxyethyl cellulose containing 2 to 8% of substituted ethylene oxide and which is insoluble in water but substantially completely soluble in a 5% aqueous sodium hydroxide solution at 0 DEG C. As shown in Fig. 1a, a fibrous mass of alkali cellulose is mechanically fed into a gas tight hopper 4 from which it is fed by means of a gas-tight power driven feed valve 5 into the lower portion of the reactor 6. The reactor comprises a helical vibratory conveyer 7 supported around a central shaft 8 and mounted on the base 9 which is provided with the vibrating device 10, and the gas tight tower structure 11. The conveyer 7 is a helical trough of rectangular cross-section, open at the top and the fibrous alkali cellulose P travels up the conveyer due to the vibration of the latter. Ethylene oxide gas is introduced into the reactor 6 through the inlet 12 and is withdrawn from the reactor through the outlet 13 for recirculation through the system. The HEC formed in the reactor 6 is discharged into the duct 14 from which it is fed through the gas-tight power-driven valve 15 into the feed duct 16 in which the HEC is conveyed into the hopper 17. The HEC is passed through gas-tight power-driven feed valve 18 into the lower portion of the reactor 20 which is similar to the reactor 6 and in which the HEC is aged by controlled oxidation with air or oxygen introduced into the reactor 20 through inlet 22. The aged HEC passes through duct 23, valve 24 and duct 25 into apparatus for washing the HEC with water and pelleting and drying the washed product. U.S.A. Specifications 2,614,102 and 2,847,411 are referred to.

Title: A method of preparing minute polymeric capsules
IPC: B01J13/10
Filed: 1967-10-04
Abstract: Microcapsules, each consisting of a wall of polymeric material enclosing a solid or liquid core particle, are made by dispersing the core material in a manufacturing liquid from which there is caused to separate a polymer-rich phase comprising a polymeric complex composed of two kinds of polymeric material joined by hydrogen bonding which coats the dispersed particles to form microcapsules in the usual way. Both types of polymer may be present in the initial manufacturing liquid, from which they are induced to separate by changing conditions, e.g. the pH may be changed or a solution of one type may be added to the system already containing the other under conditions allowing immediate formation of the complex and phaseseparation thereof. The polymer pair should comprise at least one "Hydrogen bonding acid" e.g. polyacrylic acid, poly(methacrylic acid), poly(vinyl alcohol), poly(vinyl pyrrolidone), methyl cellulose, carboxymethyl cellulose, poly- (styrene co - maleic anhydride), poly(vinylmethylether co-maleic anhydride) or poly(ethylene co-maleic anhydride) and at least one "Hydrogen bonding base" e.g. poly(ethylene oxide), poly(ethylene oxide co-propylene oxide), poly(propylene oxide), poly(vinyl pyrrolidone), poly(vinyl alcohol), poly(ethylene glycol), poly- (acrylic acid) or poly(methacrylic acid) (the designations "acidic" and "basic" being relative not absolute). The capsules may be dried in the usual way. Examples relate to the encap. sulation of stainless steel particles, ammonium dichromate and lemon oil.

Patent ES-348810-A1 (ES)
Title: Black oil conversion product separation process
IPC: C10G5/06
Filed: 1967-12-29
Abstract: A process for separating a mixed-phase hydrocarbonaceous conversion product effluent containing hydrocarbons boiling above 566 C. comprises the steps of (a) separating said effluent in a first separation zone at a temperature above 371 C. and a pressure above 68 atmospheres gauge to provide a first vapour phase and a first liquid phase (b) cooling said first vapour phase, introducing the same into a second separation zone at a temperature below 60 C. and a pressure substantially the same as in said first separation zone, and separating therein a hydrogen-rich second vapour phase and a second liquid phase principally comprising propane and heavier normally liquid hydrocarbons (c) introducing at least a portion of said first liquid phase, at a pressure less than 13À6 atmospheres gauge, into a third separation zone at a point below a mesh blanket which extends across an upper section of said third separation zone, and therein separating a third vapour phase and third liquid phase containing hydrocarbons boiling above 566 C. (d) introducing said third liquid phase into a fourth separation zone at a temperature above 371 C. and at a sub-atmospheric pressure and therein separating a residuum fraction containing hydrocarbons boiling above 566 C., and a heavy gas oil fraction boiling below 566 C. and (e) introducing a portion of said heavy gas oil fraction into said third separation zone at a point above said mesh blanket. The mesh blanket serves to prevent the entrainment of asphalts in the third vapour phase, the heavy gas oil wash removing the entrapped asphalts from the blanket. The process is particularly applicable to black oil conversion products. The second liquid phase and the cooled third vapour phase may be combined to form a product stream containing more than 60% of butanes and heavier hydrocarbons. Apart from that part of the heavy vacuum gas oil which is not recycled, the products from the final separation stage may also include a light vacuum gas oil.

Title: Device and method for reducing overheating in oil-filled electric cables
IPC: H02G15/24
Filed: 1967-04-08
Abstract: A device for reducing localized overheating in an electrical conductor having an internal duct 7 for coolant fluid either increases the rate of flow of coolant or the distance travelled by it, or both, so improving the cooling. The former may be accomplished by reducing the crosssectional area of the duct, possibly by the incorporation of a coaxial shaft 8 if a helical partition 9 is disposed about the shaft, extending radially all across the duct, both rate and distance of flow increase, the pitch of the helical partition and the cross-sectional area of shaft being calculated to give the desired Reynolds number for the flow. The coolant may be oil.
Patent ES-360565-A1 (ES)
Title: Drive units
IPC: F16H37/00
Filed: 1968-11-22
Abstract: A two-stroke engine a is connected to one element (planet carrier b) of a three-element epicyclic gear, a scavenging blower d is connected to another element (sun-wheel c), and the load (e.g. vehicle wheels) is connected to the third element (annulus wheel e) through a variable-speed power transmission T and at least one variable-speed power transmission C is coupled between the blower shaft d and either the output shaft of the engine or, as shown, the input shaft f of the transmission T. Where two transmissions C are provided, one is coupled to the engine output shaft and the other to the shaft #. As shown, the transmission C is a torque converter but may instead be a variableratio belt drive or an electrical transmission. The epicyclic gear divides the output power of the engine between the vehicle wheels and the blower d. The torque converter C modifies this arrangement by automatically transferring power from the blower d to the shaft #, or vice-versa, the effect being to keep the blower speed substantially constant. Thus, if the blower is dimensioned for the average engine speed, power is transferred from the blower to the shaft f at high engine speeds and from the shaft f to the blower at lower engine speeds. If the blower is dimensioned for low engine speed or for high engine speed, the transference of power takes place exclusively in one direction, and the torque converter C may be designed solely for operation in that direction.
