Inventor: OLSEN ERIK LAULUND
IPC: F26B7/00
Filed: 1987-02-16
Abstract: A method for heat treatment, in particular evaporation, of solutions or suspensions of temperature-sensitive substances, in which the solution is distributed over the surface of carrier members, the heat treatment is carried out under vacuum, and the substances are removed from the carrier members after heat treatment, is carried out at a temperature which is well-defined in advance and lies at a level below the temperature at which the heat-sensitive substance is damaged or deteriorates, at the same time as the method is economical in terms of energy and clean, as use is made of hollow carrier members which contain a substance which undergoes phase change at a temperature which is lower than the level at which the temperature- sensitive substance is damaged or deteriorates. In this way, it is possible to use the energy which is released at a well-defined temperature during hardening for heat treatment of the temperature-sensitive substances on the surface of the carrier members. This method can be used, for example, for evaporation of pigs' blood for producing blood meal. In this method, the substance in the hollow carrier members can be a salt hydrate which has a melting point of 32 degree C which is the approximate temperature to which pigs' blood may be exposed in order that the proteins are not denatured. <IMAGE>

IPC: B22C3/00
Filed: 1948-01-05
Abstract: 644,094. Mould materials. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Jan. 5, 1948, Nos. 290 and 13129. [Class 83 (i)] In a method of casting a chromium alloy in silica or silica-containing refractory moulds, the surface of the mould cavity is formed with a layer of chromic oxide. The invention is described with reference to the casting of chromium-steel alloys, chromic oxide being incorporated in the surface layer of the mould cavity as by spraying or painting. Where precision casting is to be used, chromic oxide may be incorporated in the coating applied to the wax pattern. A coating comprising twothirds chromic oxide and one-third silica, bonded by soap solution, waterglass and hydrochloric acid, may be used. A second coating of silica or other common coating material may then be applied to increase the strength of the coating and prevent cracking. In a modification the oxide content of the mould coating may be produced indirectly by incorporating, in the surface layer, a compound from which the oxide is formed by subsequent treatment. For example, a chromic salt may be included in the coating which is then treated with alkali to precipitate the oxide or the oxide may be formed by thermal decomposition during the moulding operation or by a preliminary heating of ammonium chromate previously incorporated in the mould coating.

Title: A process for the production of amphoteric ion exchange resins
IPC: C07F9/38
Filed: 1961-02-02
Abstract: An amphoteric ion exchange resin is made by reacting, in an alkaline medium at a temperature of at least 50 DEG C., (a) a trimethylol phenol with (b) an aliphatic imino acid containing at least 2 N-alkyl phosphonic or carboxylic acid groups or a salt of either of the acids, and (c) a phenol which contains at least 2 unsubstituted C atoms in the positions o and p to the phenolic OH group, the imino acid or salt thereof being used in an amount of from 1 to 2 mols per mol of the trimethylol phenol.  Preferably, a phenol is reacted with formaldehyde to form reactant (a) which is then condensed with acid (b) in the presence of phenol (c) to form insoluble resins, and these can be finally reacted with polyfunctional halogeno aliphatic compounds capable of reacting with both aliphatic amines and phenols, e.g. epichlorhydrin, dichlorhydrin, dichloroethyl ether and ethylene dichloride. Reactants specified are: (a) phenol and m-cresol to yield trimethylol phenols; (b) ethylene diamine-N,N1-di-, diethylene triamine-N,N1,N11-tri-, triethylene tetramine-N,N1, N11, N111-tetra-and polyethylene imine -N- methyl phosphonic and -acetic acids; and (c) phenol and m-cresol. In a typical example (1) concentrated NaOH solution is added to phenol dissolved in formalin; further phenol is added and, while raising the temperature to 60 DEG C., ethylene diamine -N,-N-di(methylphosphonic acid) tetrasodium salt is added with subsequent heating under reflux at 80 DEG -90 DEG C.; the resulting gel is then dried, ground and extracted with water.

Filed: 1971-01-08
Abstract: 1386401 Automatic speed control JOSEPH LUCAS (INDUSTRIES) Ltd 10 Jan 1972 [8 Jan 1971] 951/71 HeadingG3N In a gas turbine engine fuel supply control system, during normal operation fuel supply is controlled by an electric signal so that the actual engine speed corresponds to that of the desired engine speed, but during acceleration and deceleration upper and lower limits respectively are placed on the electric signal in accordance with prevailing engine conditions including a parameter which is not measured directly, a function generator being provided for computing the value of this parameter from other readily measureable parameters and the rate of change of one of said parameters. As shown, the fuel supply 10 of a twin spool engine is controlled by an electric signal from an amplifier 30, the fuel flow-rate F being measured by a device 12. During normal operation, in the range 0-70% maximum engine speed, an amplifier 23 provides a signal to the amplifier 30, via logic gates 28, 29, by comparing the actual engine speed N 2  measured by a device 14, with the desired speed derived from the product of the signal from a manually settable device 22 and a signal P α representing atmospheric pressure. In the range 70%-100%, an amplifier 24 provides the controlling signal by comparing the N 2  signal with the signal from the device 22, and an amplifier 25 provides the controlling signal should the maximum permissible engine speed, set by a device 27, be exceeded. The controlling signal is provided by an amplifier 38 or an amplifier 47 during acceleration, and by an amplifier 37 during deceleration. During acceleration, the signal to amplifier 38 is the product of P 1 #T 1  provided by a device 49 and f{<SP>N2/</SP>#T 1 } provided by a device 33, and during deceleration the signal to amplifier 37 is the product of P 1 #T 1  and g{<SP>Nz</SP>/#T 1 }provided by a device 34, where P 1  is the air inlet pressure, T 1  is the air inlet temperature and N 2  is the engine speed. As P 1  is not accurately measureable, its value is computed by a function generator 39 and an integrater 44 which integrates the difference between the function h{<SP>F/</SP>#T 1  P 1 , <SP>N</SP>2/#T 1 , <SP>P</SP>α/P 1 }and the differential <SP>dN</SP>2/dt to provide the value <SP>1</SP>/P 1 . When the value <SP>N</SP>2/#T 1  approaches its limit set by a device 51, the signal from amplifier 47 takes over control of the fuel supply to prevent stalling. Further control is provided by the signals from amplifiers 52, 53 and 54 which are respectively responsive to the differences between the maximum permissible air inlet temperature and the actual temperature, the maximum permissible lowpressure spool speed and the actual speed N 1 , and the pressure P 3  downstream of the compressor computed by a generator 57 and the maximum permissible pressure P 3 .
