IPC: C04B7/52
Filed: 1995-10-27
Abstract: PCT No. PCT/SE94/00389 Sec. 371 Date Oct. 30, 1995 Sec. 102(e) Date Oct. 30, 1995 PCT Filed Apr. 29, 1994 PCT Pub. No. WO94/25411 PCT Pub. Date Nov. 10, 1994A method for producing cement useful for preparing pastes, mortars, concretes and other cement-based materials, having a high workability with reduced water content, high strength and density, and a rapid development of strength, which method includes a mechanicochemical treatment of cement. The method includes a two-stage mechanicochemical treatment of a mixture of cement and at least one of two components, the first component being a SiO2-containing microfiller and the second component being a polymer in the form of a powdery water-reducing agent. In the first stage the cement and the first and/or the second component are intensively mixed in a dry state, whereby particles of the first and/or the second component are adsorbed on the cement particles. In the second stage the mixture obtained in the first stage is treated in milling equipment where the particles in the mixture receive in quick succession a large number of direct-changed impact impulses resulting in modification of the surface properties of the cement particles in the form of substantial increase of surface energy and chemical reactivity. The treatment in the second stage is carried out during a sufficiently long period of time in order that a 1-day compressive strength of a 20 millimeter per side cube of cement paste, which has been properly compacted under vibration and hardened at +20 DEG  C. in sealed conditions, at least equals 60 MPa.

Filed: 1996-11-21
Abstract: The present invention deals with a method and an arrangement for heating of pulp, in which method low- pressure steam is supplied to the pulp so that the pulp is subjected to pressure prior to the introduction of the low-pressure steam in its direction of flow, such that the pressure on the pulp at the steam introduction point is lower than the pressure on the available steam, and after the steam introduction the pulp is stirred in order to either distribute the steam evenly in the pulp and/or to equalise the temperature of the pulp. <IMAGE>

Title: Improvements in or relating to apparatus for determining the effect of an atmosphereon heated iron or iron alloy members
IPC: G01N27/12
Filed: 1951-01-18
Abstract: 697,807. Electric indicating systems. GENERAL. ELECTRIC CO., Ltd., DOVEY, D. M., and HOW, I. M. Jan. 18, 1952 [Jan. 18, 1951]. No. 1414/51. Class 40 (i). To determine the suitability of an atmosphere to be used in the heat treatment of iron, e.g. preparatory to hardening, an iron wire 10 is fed intermittently or continuously from a reel 19 through a transparent tube 11 and heated by passing an electric current there through by way of spring contacts 20, 21 to slightly above 925 ‹C in the presence of a carburizing atmosphere to be tested which is fed to the tube through a duct 14. The wire is then quenched to give a Martensite structure by cutting off the heating current, and when cooled its resistance between the contacts 20. 21 or contacts 22-23, 28-29 is measured, the resistance value indicating the carbon content of the wire which has been obtained from the atmosphere. The temperature of the wire when heated is determined by supplying a known A.C. or D.C. heating power thereto or by means of a radiation pyrometer for which purpose the hot wire is viewed against a black background provided by a C shaped element 31 within the tube. This element is also provided with a scale 32 against which the sag of the wire 10 on cooling, which is also a function of the carbon content, may be read. The contact pairs 22-23, 28-29 are out of contact with the wire during heating and brought into contact with the wire after cooling by rotating knobs 26, 30 which through cams 24 bring the contacts of the respective pairs into engagement with the wire. Heating and measuring circuit, Fig. 2. The wire 10 is heated by throwing a four-pole switch 51-54- 57-60 to the left when the wire is series connected with a resistor 47 across the secondary 40 of a mains fed transformer having a variable series reactance 43 and a tapping switch 42 to give a constant output voltage which is measured by both meters 48, 50. Throwing the four pole-switch to the right breaks the heating circuit and connects the wire 10 in series with the resistor 49 and meter 48 across the secondary 40 to pass a much smaller current through the wire. This current is measured by the meter 48, and the voltage across the wire 10 is measured by the meter 50, from which readings the resistance is derived. The resistance could alternatively be measured by a bridge circuit.

Title: Purification of ethers of alkylene glycols by distillation
Inventor: RIDLEY KENNETH FRED
IPC: C07C41/42
Filed: 1955-01-18
Abstract: Ethers of alkylene glycols, prepared by reacting an alkylene oxide with a monohydric alcohol are freed from unetherified glycol by-products of the reaction by submitting the crude reaction product to fractional distillation in the presence of an aromatic or terpenic hydrocarbon capable of forming with the glycol an azeotrope having a boiling point not less than 20 DEG  C. away from the boiling point of the ether.  Examples are given wherein the azeotrope distils over first, and is followed by the purified ether.  The amount of the hydrocarbon added to the reaction product should preferably be approximately equal to the amount of alkylene glycol present. Pseudocumene, naphthalene or terpinolene may be used for the purification of diethylene glycol monoethyl ether.  In the case of the monomethyl ether, the auxiliary liquid may be pseudocumene, or butyl benzene.  In the separation of diethylene glycol from the triethylene glycol monoethers, suitable azeotropeformers are methyl naphthalene and 1.3.5-triethyl benzene.  The purified ethers may be used as additives to gasoline to obviate icing in carburetters in cold, humid weather.  Specification 709,987 is referred to.

Title: Process for the preparation of plastic masses and products obtained thereby
IPC: C08G75/16
Filed: 1941-02-04
Abstract: Plastic masses suitable as rubber substitutes or for mixing with rubber mixes to be vulcanised are obtained by adding a mixture of aniline, ethylene chloride and formaldehyde to a solution of an inorganic polysulphide and reacting the mixture in the presence of a 2 per cent aqueous solution of phenol as catalyst, the mixture being heated to start the reaction which is then controlled by cooling. The hardness of the product may be increased by increasing the percentage of sulphur in the polysulphide; polyselenides may be used instead of polysulphides. The plastic masses obtained may be dissolved in terpenes.  The Specification as open to inspection under Sect. 91 describes the use of urea or amides instead of amines and acetic, anisyl, benzyl, tolyl, procatechu aldehydes or acetone instead of formaldehyde; dihalogenated derivatives of other hydrocarbons or their derivatives may replace the ethylene chloride. This subject-matter does not appear in the Specification as accepted.
