Patent NL-9200381-A (NL)
Title: Tension-resistant sleeve coupling
IPC: F16L21/02
Filed: 1992-03-02
Abstract: A tension-resistant (tension-proof) sleeve for coupling two butted (abutting) tubular ends of pipelines and/or fittings therefor. The sleeve consists of a tubular body, a clamping means acting between the outer wall of the pipe and the inner wall of the tube, the tube being set into an annular body lying against its end face and being made of tension-resistant material, said body being bonded to a layer of tension-resistant material arranged round the tube. This makes it possible for a tubular sleeve to be made of low-grade material and consequently relatively inexpensively, while still allowing large tensile forces to be transmitted by the annular body.
Patent NL-9400378-A (NL)
Title: Plastic cartridge which is made from a single piece and is provided with funnels
Inventor: OUD SJAAK
IPC: A01K1/015
Filed: 1994-03-10
Abstract: The invention relates to plastic cartridges which are made from a single piece and have funnels which can be fitted beneath grate floors in cowsheds and pigstys. This prevents the release of gases formed from the semi- liquid manure, since the open surface area of the grate is reduced to a few holes with a cross section of 70 mm. In combination with a pushing/rinsing system, it is possible to move the manure into the cellar quickly, so that the emission of gases can be limited to a minimum. This also keeps the funnels clean. When the cellar is not full up to the funnels, a small amount of gas may be released through the funnels. However, if the cellar is full all the way up to the funnels, gases are no longer released, since the funnels are closed. The cartridges can be made suitable for all grate dimensions and can be fitted both in new sheds and in existing sheds. <IMAGE>

Patent SE-8901012-A (SE)
IPC: B43K23/012
Filed: 1989-03-22
Abstract: The invention relates to a writing and drawing arrangement, referred to as a finger pen (2, 3, 4). We have clung to the traditional notion that pens or pencils must be rod-shaped in spite of the fact that this subjects the fine-motor function of the user to unnecessarily stringent demands. A study of the development of the fine-motor function of children proves that a semi-supine grip on rod-shaped pens or pencils can normally not be achieved out before the age of 6-7 years. The invention solves this problem by means of a finger pen (2, 3, 4), prone holding (1) of which is already possible at an age of 2-3 years, which generally makes possible its use in a manner which as regards the fine-motor function is simplified. Pen nib (5) projects from or in the vicinity of sensible centre of feeling (7) of writing/drawing finger (6) and is so angled that the point at which it contacts the writing/drawing surface will be seen by the user. Various alternatives of finger pen (2, 3, 4) are possible, e.g. of open type (2), closed type (3) or contoured shape (4). The invention applies mainly to writing/drawing while holding the pen in a prone position (1).
Patent SI-9600233-A (SI)
Title: Resonance transducer
Inventor: Godec Igor
IPC: H02M1/10
Filed: 1996-07-22
Abstract: The resonance transducer represents a new approach in constructing transducer for the supply of three-phase resistive-inductive loads. The electrical drawing of the transducer is very simple. By featuring only six switching elements (S1, ..... S6) it surely represents a step forward in the development of resonance transducer circuits. The main advantage of the resonance transducer is doubtlessly the increased effectiveness and power factor because of the soft switch mode and by this producing considerably less noise in the power network compared to his predecessors (VSI transducers).
