Patent NL-7207374-A (NL)
IPC: G10L19/02
Filed: 1972-05-31
Abstract: There is disclosed herein a vocoder system having a multichannel speech analyzer, a multichannel speech synthesizer and an excitation system for extracting time-varying characteristics of the excitation function of the input speech signal and reproducing this function for the excitation of the synthesizer. The excitation system includes a speech extractor, a voiced/unvoiced detector, a pitch generator, a noise generator, a voiced/unvoiced switch and an output pulse generator. The pitch extractor operates on the short term envelope of the speech and is derived from a signal which is the sum of the signals of all analyzer channels. Constant width pulses are generated and integrated to form a varying d.c. signal proportional to the frequency of the extracted pitch. During voiced speech a multivibrator controlled by the d.c. signal produces the input to the output pulse generator. The output pulse generator produces an output pulse train of constant energy and is applied for excitation of the synthesizer channels. During unvoiced speech the noise generator drives the output pulse generator.

Patent NL-7711544-A (NL)
IPC: G01B3/04
Filed: 1977-10-20
Abstract: A microscopic length scale typically about 50  mu m long and graduated in several intervals ranging from 1  mu m to 20  mu m. The scale is useful in calibrating the magnification of scanning electron microscopes (SEMs) and other electron imaging instruments. The scale comprises alternating layers of two metals deposited on a substrate. The two metals have substantially different electron emission coefficients to provide contrasting emission signals when scanned by an electron beam. One of the metals, preferably gold, is deposited in uniform layers about 40-80 nm thick. The other metal, preferably nickel, is deposited in several layers ranging from 1  mu m or so thick near the substrate to 20  mu m thick in the outermost layer. The resultant multilayer composite is cut into one or more samples and each sample is mounted on edge. The exposed edge is ground and metallographically polished and a microscopic indentation is made in the substrate near the first gold layer. The indentation defines a reference region, and the distances between the first gold layer and the subsequent gold layers in the reference region are measured. The measurement is made using a similar sample which was previously calibrated with the aid of a polarizing laser interferometer.

Title: Pipe section with sealing ring in internal groove - produced in single operation using elastomer as pressure medium
IPC: B29C45/14
Filed: 1978-09-27
Abstract: The pressure medium used to expand a zone of a thermoplastic pipe section into a cavity in the mould wall outside the pipe, so as to form an internal circumferential groove is a deformable, thermoplastic, elastomeric base material. This forms the sealing ring to be inserted into the groove, and it is brought to the correct shape and stabilised. The pipe section is produced by means of a mould with an approx. tubular modular cavity, which is filled with plastic material. An annular cavity is then produced in the mould on the outside of the pipe section, and opposite, this, inside the pipe, the pressurised medium is applied. Used to reduce the production time necessary for the forming of the internal groove and the fitting of the elastic sealing ring.

Title: Detecting weld leak in reactor tubes carrying combustible gas - by tensioned fuse wire adjacent to welds activating alarm when breaking
IPC: G08B17/02
Filed: 1979-11-07
Abstract: The arrangement is intended for detecting a leaking weld in a reactor (1,2) in which externally heated vertical reactor tubes (3) are welded to horizontal outlet tubes (4). During operation the tubes carry hot gas which is combustible when in contact with air. A short distance above the welds, a wire (5) has one end held (7) at a fixed point whilst the other end is weighted (13) or otherwise loaded to tension it. Material and dia. of the wire are such that it withstands the tension at normal operating temp. but softens or fuses above the permissible temp. level. The resulting break due to ignition of escaped gas activates an alarm, control or safety mechanism. Used as a reforming reactor for pressure reforming of natural gas with stream to produce hydrogen for the manufacture of ammonia. Simple, reliable and rapid detection is achieved, with easy localisation of failed weld by withdrawing broken wire end and measuring its length.

Patent NL-8702804-A (NL)
IPC: G02F1/29
Filed: 1987-11-23
Abstract: Method and device for controlling a beam of light (17), which is coupled in into a working layer (2) of electro-optical material and which is supplied to a working area (16). In a first optically conductive state the working area has a poling mode which differs from the one of the surrounding working-layer material (7), as a consequence of which other refractive indices will arise, due to which the working area will form a light waveguide through which the beam of light coupled in will be conducted (19) to a first glass fibre (22). In a second optically conductive state the working area has a poling mode whioh is equal to the one of its surroundings. Because of the fact that the refractive indices inside and outside the working area are now equal, the working area will not form a light waveguide, but (e.g.) a light insulator or a light reflector, by means of which the beam of light coupled in will be conducted to a second glass fibre (21). The quasi-stationary poling mode of the working area required for the first respectively the second optically conductive state will be reached by successively - warming up the working area to above the softening temperature, - exciting an electric field in the working area, and - letting the working area cool down again. For poling the electric field has a value unequal to 0; for unpoling a value equal to 0.

Title: Incorporation of plastic waste into asphalt
IPC: C08L95/00
Filed: 1992-10-12
Abstract: Traditional asphalt has certain characteristics, for example stability Pm, flow Fm, quotient Qm. My invention relates to the incorporation of plastic waste into asphalt. Studies show that incorporation of plastic waste into asphalt produces asphalt having better characteristics than asphalt into which no plastic waste has been incorporated. The stability value Pm, depending on the concentration (%) of plastic waste is generally 3 to 4 times better. At the same time, my invention has beneficial environmental aspects, namely the utilization of (plastic) waste and savings in natural raw materials (for example sand).
