Title: Depolarisation circuit for electrodes in rotating container - has magnetic field at right angles to gap with suspensions
IPC: G01R35/00
Filed: 1975-07-22
Abstract: Depolarisation circuit for electrodes in a disc shaped container which can rotate about a central axis. The electrode plates are at right angles to the axis.

Title: Rolling wheel rims from profiled strips - without adjustment in machine having two three-point-acting roll assemblies
IPC: B21D7/08
Filed: 1978-06-29
Abstract: An originally straight profile is performed at its ends and is then fed through rolls acting at three points. During rolling the centre lines of the three rolls of the machine remain in their position. The centre line of the middle roll is adjusted before rolling relatively to the two others, so as to give a radius which is smaller than that called for in the end product. The curved profile is then brought back to the required radius by an additional roll, which is on the same side of the profile as the middle roll. Used for prodn. of bicycle wheel rims from a straight profile which is first of all preformed at the ends, and then passed through a rolling machine. The method is very simple, dispensing with the need for measuring and adjustment of the middle roll during working, and giving a rim with the exact diameter required.

Patent NL-7909298-A (NL)
IPC: B28B23/02
Filed: 1979-12-22
Abstract: The invention relates to a process for the manufacture of objects from water-hardened materials, reinforced with one or more reticulate webs, one over the other, which webs have been obtained by stretching, fibrillating and spreading of a film of organic polymeric material, by continuously supplying one or more reticulate webs, contacting them with a water-hardening material and water, thus forming a composite material, and shaping and hardening this material. This is obtained according the invention in that: a. one or more reticulate webs, one on top of the other, are continuously supplied and laid on a carrier; b. the reticulate webs are folded zig-zag on this carrier; c. the folded network is continuously transported in a direction virtually normal to the direction in which the reticulate webs are supplied; d. subsequently, the folded network is contacted, directly or indirectly, with a water-hardening material and water. The rate of supply of the reticulate webs to be folded and the rate of discharge of the folded networks is such that the angle between two successive folded sides of the reticulate webs is between 1/2 DEG  and 120 DEG , in particular between 50 DEG  and 90 DEG  and most in particular between 1 DEG  and 20 DEG . Reticulate webs are applied to one side or to both sides of the resulting folded network, which webs have been stretched and fibrillated longitudinally and in the transport direction and are supplied in the direction of motion of the folded network, and in particularly, at only one of the two sides of the resultant folded network, reticulate webs stretched in the transport direction are applied, and at the other side only one or two of such webs. The resulting folded network packages are integrated to a whole by welds at the sides and passed between two rollers prior to being contacted with a water-hardening material.
Patent NL-8000668-A (NL)
IPC: B27K3/34
Filed: 1980-02-01
Abstract: A method for treating wood to enhance its properties in which the wood to be treated is contacted with sufficient water dilutable resin in a water miscible solvent and water to deposit the resin in the cell walls of the wood fibres, the resin containing molecules of a size which can enter the free space in the cell walls, and the resin in the cell walls is then converted to a water insoluble form. The treatment provides wood of improved dimensional stability and resistance to checking or splitting on exposure to water. Further improvements in the wood properties can be obtained by depositing additives such as preservatives or fire retardants in the cell walls of the wood and fixing the additives therein with the insolubilized resin.

Patent NL-9101606-A (NL)
IPC: C08G69/28
Filed: 1991-09-24
Abstract: The invention relates to a process for the production of high-molecular-weight polytetramethylene adipamide from equivalent amounts of 1,4-diaminobutane and adipic acid at lower pressures. By supplying 1,4-diaminobutane at an advanced stage of the polycondensation a first polycondensate is obtained that can be extruded very well and that can be aftercondensed in the solid phase to obtain a product with a high molecular weight within a short time. Because of this a substantial overall gain in time is realised. It even appears to be possible to prepare a first polycondensate with a relative viscosity that is high enough for the polycondensate to be further processed into shaped objects. The polycondensation can be carried out both in the melt and in solution. The diaminobutane can be supplied both via the liquid and via the vapour phase.

Patent NL-9102135-A (NL)
Title: Method for bringing about a connection between pieces of wood
IPC: E06B3/984
Filed: 1991-12-19
Abstract: A method for bringing about a connection between pieces of wood, such as the parts of a wooden window frame (door frame). The parts are made into desired sections, and the surfaces which are to be connected to one another are provided with pinholes for receiving pins. Before these pins, which are preferably made from a fibre-reinforced plastic, are pressed into the pinholes, all the end faces of the pieces of wood are treated with an impregnating agent. This agent preferably comprises a two-component plastic which is based on epoxy resin. After this agent has cured, the treated surfaces are provided with a layer of adhesive, and spacers, for example in the form of rings around the pins, are placed between the surfaces which are to be connected to one another. Then, the surfaces which are to be connected to one another are provided with a layer of strongly elastic filler and are placed against one another. This strongly elastic layer and the slightly flexible pins absorb stresses which may arise as a result of the action of the wood. The risk of cracks being formed in the pieces of wood, and consequently the risk of the wood rotting, is thus considerably reduced.
