Patent NL-6815932-A (NL)
IPC: G01B9/02
Filed: 1968-11-08
Abstract: 1,243,359. Light modulators. COMPAGNIE GENERAL D'ELECTRICITE. 8 Nov., 1968 [10 Nov., 1967], No. 53164/68. Heading H4F. [Also in Divisions G1 and G2] Small displacements are detected by coupling them to one mirror of a Fabry-Perot interferometer, detecting the intensity of light passing through or reflected from the interferometer, feeding back a signal to a transducer tending to keep the variations in mirror spacing less than #/4 and using the fed back signal as an indication of the displacements. The interferometer 1, which is illuminated by a He-Ne laser 4, comprises mirrors 8 and 9 coupled to a piezoelectric ceramic or magnetostrictive cylinder 16 rigidly and by a diaphragm 11 respectively. The light intensity emerging at 10<SP>1</SP> or 10<SP>11</SP> is measured by a photo-cell 12 and compared with a reference signal from a photocell 7 and any difference energizes the cylinder 16 to reduce the difference. The laser may be modulated at a high frequency to facilitate amplification, the high frequency signal being filtered out of the feed back loop. Microphones.-Sound vibrations incident upon the mirror 9 produce corresponding signals at the output S. For high frequency response the interferometer is supported at the mirror 8 end and is vented to the atmosphere. For low frequency response, it is supported at the other end; fluid-tight and provided with a smaller aperture diaphragm. The device may be used as an accelerometer by using the mirror 9 or a body attached thereto as seismic mass.

Title: Bitumen modified - phenolic foams
IPC: C08G8/28
Filed: 1970-02-25
Abstract: Foamed products are made from mixtures of bituminous materials (I) with phenols and hexamethylene tetramine condensed in the presence of an alkaline catalyst and aldehydes at temp. 140-200 degrees C for 4h. The expansion takes place under pressure at 165-180 degrees C using hexamethylene tetramine as blowing agent. I are asphalt, petroleum bitumens, pitch and cold tar in proportion 50-70% of bitumen plus phenols. Bitumen based foams are usually dimensionally unstable. The present process provides rigid foams much cheaper than other foams, with good compression strength. The foams do not contain free acid and are therefore noncorrosive to metals, and heat resistance is as good as straight phenolic foams.

Title: Bladed screw type compressor - has blade comprising numerous plates thrust against rotor by lubricating oil pressure
IPC: F04C18/107
Filed: 1975-11-05
Abstract: Screw-type compressor has a rotor (1) with one or more starts, the depth of which decreases towards the high-pressure end. It runs and forms a seal in a cylinder with front and rear covers (6, 7), near to or in which there are suction and pressure ports (4, 3). A blade (2) extends in the axial direction in the cylinder, reducing the compressing space in the latter in conjunction with the rotor. The blade is built up of a large number of small thin plates, together bearing as a laminated packet continuously against the rotor surface under the effect of oil pressure. The oil also serves as a lubricant between the plates, and acts as injection oil and a seal for the compression chamber, in addition to dissipating heat.

Title: Self-adhering plastic foil symbol elements - have e.g. letters printed on rectangular foil pieces providing correct alignment and spacing
IPC: G09F7/12
Filed: 1982-09-06
Abstract: The plastic foil elements carry symbols and can be peeled off and affixed to a smooth surface e.g. to show a text on a shop window. The elements are rectangular and are larger than the symbols (e.g. letters). They have equal height whilst their widths vary according to the symbols, such that on assembly side-by-side, e.g. to form words, the correct letter spacing is obtd. The foil is preferably of the statically self-adhering type, such as soft PVC, whilst the symbols are printed using an ink which adopts the statically adhering property of the foil. Elements may be assembled e.g. to make advertising text or used as game of draughts, etc. When assembled side-by-side the elements themselves provide the correct spacing whilst their upper or lower edges enable correct alignment. The elements can be peeled off with minimum or no distortion of the symbols so that they can be re-used.

Title: NMR distribution in region of body determining method - filling image frequency matrix by means of successive zigzag patterns shifted wrt one another
IPC: G01N24/08
Filed: 1984-11-28
Abstract: An R.F. electromagnetic pulse is generated in order to cause a precessional motion of the magnetisation of the nuclei in a body. Then, after a preparation period, an alternating, periodic gradient magnetic field is generated during a measurement period or periods, each period being divided into sampling intervals for taking a corresponding number of signal samples of the resonance signal generated from the body. Each time after a waiting period, the above steps are repeated a number of times. The duration of the preparation period and/or the integral over the preparation period of at least one gradient magnetic field applied during the preparation period each time has a different value in order to provide a set of signal samples from which, after a signal transformation, an image of a nuclear magnetisation distribution is determined. The period of the sampling interval is at least a factor of 2 shorter than the period of the alternating periodic gradient magnetic field which at the most equal the measurement period.

Title: Detecting undissolved gas in hydraulic control system
IPC: F15B21/044
Filed: 1992-01-23
Abstract: Undissolved gas in a hydraulic control system contg. a hydraulic medium pressure pump and a feed reservoir, is detected by (a) checking the compressability of the medium; and (b) deducting the amt. of undissolved gas by taking into account that an increase of the amt. of undissolved gas in the medium results in a decrease of the compressibility of the medium.

Patent NL-9200499-A (NL)
IPC: H04N7/26
Filed: 1992-03-17
Abstract: Known systems based on pyramidal video-coding and video-decoding code and decode with insufficient efficiency. By feeding back, in each layer of the coding system, the data processing means present in the layer via memory means, only so-called difference pictures are coded, which increases the efficiency considerably. The decoding system should then similarly be provided with fed-back memory means and, as a result, normally attains a very complex scope, which is avoided, however, if in the coding system coupling between two adjacent layers takes place in the highest layer thereof with two different points of the feedback loop. <IMAGE>

Title: Process for preparing a synthetic polymer latex composition and method of paper coating using such composition
Inventor: LEE DO IK
IPC: D21H19/10
Filed: 1987-04-30
Abstract: This invention relates to an improvement in the production of low sheet gloss coated papers which comprises using as the synthetic polymer latex binder for the aqueous coating composition employed to coat the papers, a carboxylated latex which substantially swells during the preparation of the aqueous coating composition and subsequently shrinks during the drying of the coated paper, whereby a microscopic surface roughness is obtained to yield a low sheet gloss coated paper while retaining high ink gloss without detrimental effect on ink gloss, or the printing characteristics of the coated paper. Carboxylated latexes and their methods of preparation are generally taught in the art. The carboxylation is introduced by utilizing as one of the comonomers in the preparation of the latex a vinyl acid, such as acrylic acid, methacrylic acid, itaconic acid, fumaric acid, and maleic acid. The carboxylated latexes suitable for use in this invention are those which contain at least 6 parts of a vinyl acid monomer per 100 parts of total monomers. Using these carboxylated latexes as the binder for the aqueous coating composition employed to coat papers produces low sheet gloss coated papers to be prepared without the use of large pigment particles and/or specialized supercalendering techniques.
