Patent NL-8300033-A (NL)
IPC: G06F13/00
Filed: 1983-01-06
Abstract: The invention relates to a broad-band, time-division multiplex, token-passing, ring local area network, with which both circuit-switched and packet-switched traffic, namely data, text, picture and speech traffic can be supported. The invention has for its object to provide a method of transmitting digital information in a ring having a comparatively high transmission capacity with which rapid access to the common ring transmission means can be obtained, without however high requirements being imposed on the processing speed of the stations. According to the invention this is in principle achieved by means of a method which guarantees that per time-division multiplex frame only one time slot, which is known to the station, needs to be accessed.

Patent NL-8901921-A (NL)
IPC: A01N25/10
Filed: 1989-07-25
Abstract: The invention provides a dispensing composition for the controlled release of semiochemicals, such as pheromones, wherein the semiochemical is enclosed in a network of a crosslinked polymer which is substantially free of radical initiator residues. The dispensing composition can be prepared by mixing a prepolymer with the semiochemical and optional additives and crosslinking the mixture by means of gamma radiation or electron beam treatment, or by UV radiation or heat in the presence of a radical initiator, the residues of which are subsequently extracted. The prepolymer is preferably an acrylate or methacrylate terminated prepolymer. The rate of release of the semiochemical can be varied by modifying the network density, the type of prepolymers, the degree of loading and the shape of the dispenser. Vulnerable semiochemicals can be stabilized by adding stabilizers, such as UV absorbers and antioxidants. The predetermined release rate can be sustained for several months. The composition can be shaped or applied as a coating.

Title: Mechanism for synchronized movement of window casement shutters
Inventor: SODNIK IVAN
IPC: E05B9/04
Filed: 1998-02-17
Abstract: The subject of the presented device is a purely mechanical and therefore permanent mechanism for synchronized movement of casement shutters (1, 2) for windows and doors, extremely cheap and under correct selection of materials suitable for all climates. During shutting or opening of the shutters (1, 2) it is always unconditionally ensured that the overlying shutter (1) during opening outgoes the covered shutter (2) and vice versa, that the underlyed shutter (2) during closing outgoes the overlying shutter (1). Apart from the possibility of automation, the presented mechanism also ensures that the shutters (1, 2) when open, are protected against uncontrolled movements due to wind and similar environment impact. Thanks to the assistance of the screw spindle (4) connected via nuts (50, 60) and further on to operating handles (51, 61) with wings (52, 62) and in this way attached fastening handles (11, 12) with shutters (1, 2), the underlying shutter (2) hinged on the turning point (210) of the corresponding handle (21) is delay foldable with respect to the folding of the overlying shutter (1) as a consequence of the turning of the screw spindle (4) into one direction. On the other hand the turning of the spindle (4) into the opposite direction during shutting of the shutters (1, 2), the shutter (1) is delay foldable with respect to the underlyed shutter (2).
