Patent NL-7414750-A (NL)
Title: Magnetic separation equipment for metal particles - has housing with stationary magnetic inclined walls over which material flows
IPC: B03C1/26
Filed: 1974-11-12
Abstract: The equipment separates metal parts from bulk material, and comprises a roughly vertical housing, part of whose walls are inclined so that the material comes in contact with them as it flows through. These inclined wall sections (6) arranged one above the other in the housing (4) are partly or wholly formed of stationary magnets (9), or of magnetisable material behind which stationary magnets are mounted. The sections can be arranged to swing clear, to allow removal of the metal accumulated on them, being held in the closed position by easily-operated hand levers (8), acting at the opposite ends to the hinges (7).

Title: Testing for softening temp of thin coatings - by determining the capacitance change beneath an indenter
IPC: G01N25/04
Filed: 1975-05-14
Abstract: The softening temp. of a thin (non-conductive) coating applied to the surface of a conductive substrate is determined by applying an indenting foot with controlled force upon the surface of the coating and monitoring the electrical capacitance of the foot/coating/substrate. The onset of softening is indicated by a sudden increase in the capacitance of the system. Method is used for detg. the softening point of thermoplastic coatings, and is more sensitive than simple mechanical displacement transducer test systems, applicable to thinner coatings, i.e. down to 1-2 mu.

Title: Polymerization of water-sol monomers using radiation - and chemical initiator, terminating radiation before end of polymerisation
IPC: C08F2/54
Filed: 1975-12-08
Abstract: Water sol. linear, high mol. wt. polymers are prepd. by irradiating an aq. soln. of 10-60 wt.% of a water-sol ethylenically unsatd. monomer(s) of formula: (where R=H, CH3 or C2H5 and Y=-NH2, -OM, where M=a cation, R, R2 and R3 are 1-4C alkyl, and X=an anion ) and 5-5000 ppm of a free-radical initiator having a dissociation constant of above 1 x 10-4 recip. secs. at 100 degrees C, acting or effective mainly between 50 and 100 degrees C. Radiation intensity is from 1000 to 1,000,000 rads/hr. to a dose of 1000 to 150,000 rads. nd is terminated before formation of water-insol. polymer in the reaction mass, allowing chemically induced polymerisation to continue. 30-95 wt.% of the unsatd. monomer initially present is converted to water-sol. polymer before termination of radiation. In producing water-sol. polymers in the form of a pourable liquid or a non-pourable rubbery gel. Termination of radiation before completing the polymerisation avoids any cross linking of the polymer. As the polymerisation reactions are exothermic and sufficient temp. is reached to induce chemically initiated polymerisation, this will continue until almost all of the monomer is converted to polymer.

Patent NL-7614239-A (NL)
Title: Nickel plating baths with reduced nickel ion concn. - contain magnesium and chloride ions, and give ductile electrodeposited nickel layers with reduced environmental pollution
IPC: C25D3/12
Filed: 1976-12-22
Abstract: Nickel plating baths for electrodeposition of glossy or semi-gloss nickel layers are made with a low nickel ion concn. (in comparison to the Watts bath compsn.) of 0.2-.0.9 gramion Ni2+ per litre, together with sufficient of a magnesium salt to give a ratio Mg2+/Ni2+ of 1-15 and a Cl- ion concn. of 1-5 gramion/1. The baths may also contain the usual additives such as glossing agents. The presence of Mg2+ and Cl- ions allows nickel plating baths to be made with lower concns. of Ni2+ ion thanin normal Watts baths. In contrast to earlier low nickel concn. baths, the new baths give nickel layers which have high ductility, are free from internal stresses, give better coverage in areas with a low cathode current density, and which are not sensitive to the presence of impurities such as glossing agents. The low nickel ion concn. reduces losses of heavy metal and results in less environmental pollution.

Title: Steel prodn. in refractory lined converter - by blowing oxygen onto charge of liq. metal and liq. slag comprising lime and recirculated granulated steel slag
IPC: C21C5/32
Filed: 1979-06-19
Abstract: Steel is made in a steel converter lined with refractory brick, whereby oxygen is blown from above onto the charge of liq. metal and liq. slag in the converter. The slag used is free from fluorspar and is comprised of (per ton of finished steel) 40-47 kg lime and 15-25 kg recirculated granulated steel slag. In a pref. process, the crude liq. iron fed to the converter has a Mn content of 0.6-0.75 wt.%, esp. about 0.7wt.%; 42-45 kg lime and 16-18 kg steel slag is metered into the liq. metal; the lime is metered in a single lot at the beginning of the oxygen blow; the comminuted steel slag has a particle size of 25-70 mm; and the lime used is dolomitic lime. Process allows prodn. of steel using smaller amts. of lime per ton of finished steel than in prior art processes (e.g. 40-47 kg against 60-70 kg previously). The slag produced is less aggressive than in known processes, so that the refractory brickwork has a longer life and the process is more economical to run.

Abstract: A digital dynamic range converter of the forward control type for varying the dynamic range of an audio signal which is available in digital form and is constituted by a sequence of audio signal samples. In the multiplier device 5, each audio signal sample x(n) is multiplied by a control signal sample s(n) which is delivered by a digital control signal generator 7. This control signal generator 7 has applied to it unipolar signal samples x(n) which are derived by means of a transmission channel 9 from the audio signal samples x(n).In order to cause this dynamic range converter to respond rapidly to abrupt variations in the audio signal and to render it moreover universally usable, the control signal generator is provided with a digital peak-value detector 11 which converts the sequence of unipolar signal samples x(n) into a sequence of peak-value samples x(n). The latter are applied to an adjustable digital non-linear amplitude transformation circuit 12 which has an adjustable amplitude transmission characteristic curve determined by adjustment quantities R and a. It delivers the transformation samples sin) which are preferably converted in a digital low-pass filter into the control signal samples s(n) which are applied to the multiplier device.

Title: Process for preparing biomass attached to a carrier
IPC: C12M1/16
Filed: 1980-08-05
Abstract: A granular carrier is contacted in a reaction space with a continuous stream of liquid which contains a sufficiently wide flora of microorganisms and sufficient nutrients for the growth and /or preservation of the microorganisms until a sufficiently thick layer of microorganisms is attached to the carrier, while in the liquid 0.1-1.5 kW of mechanical energy per m<3> of reactor liquid, is dissipated at least partly in the form of gas bubbling through the liquid and the residence time of the liquid in the reaction space is kept lower than the reciprocal maximum growth rate of the microorganisms. More preferably an aerobic biomass attached to a carrier is produced, by applying liquids, wherein the growth rate is not limited by the concentration of nutrients and by adjusting a residence time of the liquid in the reactor of below 45 minutes. 
<??>The process can be applied for the production of all kinds of biomass attached to a carrier, e.g. biomasses as are applied in the biological purification of waste-water, aerobic biomass, anaerobic biomass, nitrificating biomass and denitrificating biomass, as well as biomasses forming a desired metabolic product which inhibits its own production rate at higher concentrations, e.g. biomass for the production of alcohol.
