Patent NL-7903890-A (NL)
Title: Filtering needle hub for hypodermic syringe - with compacted filter wad formed from continuous length of filament yarn
IPC: A61M5/31
Filed: 1979-05-17
Abstract: The filter is constructed by placing the empty hub housing at one end of a tube and the filter retaining spider insert at the other end of the tube while the yarn is fed into the tube at its mid-point. A blast of air carries the fibre towards the spider where the yarn accumulates. When sufficient yarn has been supplied the spider is pushed along the tube to carry the yarn wad into the housing where it is compacted and retained by the spider. The hub with its filter are now discharged from the tube. The filter removes debris from liquids being injected via a hypodermic syringe. The filter is formed from a continuous length of yarn and thus does not release short fibres into the liquid being injected.
Patent NL-7904164-A (NL)
Title: Semiconductor device esp. MISFET prodn. - using silicon nitride film obtd. by direct nitriding to prevent ion implanted impurity migration during heat treatment
IPC: H01L29/10
Filed: 1979-05-28
Abstract: Semiconductor device, esp. MISFET prodn. involves implantation of an impurity in a semiconducting Si substrate and heating. The novel feature is that a Si3N4 film, esp a gate insulating film of the MISFET, is produced on the substrate by direct thermal nitriding, so that the total amt of ion implanted impurity is retained at the surface of the substrate after heating. Specifically, the Si3N4 film prevents redistribution of the implanted impurity from the substrate into the Si3N4 film when the substrate is heated to activate the impurity and correct damage to the substrate caused by ion implantation.
Patent NL-8001578-A (NL)
Title: Automatic door-locking system - permits entry only to card holders, but does not restrict exit, and uses microswitches to control locking mechanisms
IPC: E05B63/16
Filed: 1980-03-17
Abstract: This door-locking system is of the type which allows access only to persons who insert a coded plastic card into a slot. When the card has been recognised, the mortise part of the night-lock is freed, allowing the visitor to open the door by operating the handle and thus the catch. When the card reader recognises a valid card it transmits a pulse to the input (17) of the lock circuit. The pulse switches on a transistor (19) which allows a capacitor (20) to discharge through the mortise freeing a solenoid (21). The solenoid is kept energised until a microswitch (26) indicates that the visitor has opened the door. The mechanical construction of the lock is such that operation of the inner handle overrides the card reader by means of another microswitch (3), allowing a visitor to leave. However, operation of the outer handle does not operate this microswitch.
Patent NL-8100417-A (NL)
Title: Concentric plastic tubes with plastic foam-filled annular space - are held apart by T=section plastic spacers
IPC: F16L59/12
Filed: 1981-01-28
Abstract: The spacer is intended for maintaining distance between an outer tube and a co-axial inner tube, the annular space between them being filled with plastic foam material. It is formed as a plastic, e.g. PVC, T-section of which the end of the vertical portion engages the outer tube whilst the cross-bar directly or indirectly engages the inner tube. The cross-bar may have at least one projection to prevent its displacement. This projection may be formed as a ridge. The cross-bar and projections preferably have a lesser wall thickness than the vertical portion. The inner tube may be in glass fibre-reinforced plastic whilst the outer tube is in poly-alkene material.
