Patent EP-0298120-A1 (EP)
Title: Tabular acicular gypsum and method of filling paper.
Inventor: JOHNSTONE NORMAN E
IPC: D21H/
Filed: 1988-01-11
Abstract: A tabular variety of acicular gypsum crystal filler is prepared by hydrating calcium sulfate dihydrate particles in a seeded continuously stirred reactor at a low level of super-saturation to obtain crystals having an aspect ratio of about 100:10:1 and average length in the longest dimension of about 100-450 micrometers. For the manufacture of paper, the obtained tabular crystal slurry may be directly added to the paper pulp before web formation to obtain a filled paper having high filler retention.

Title: Process and device for processing knitting yarn along the edge of a knitted article
Inventor: GOLLER ERNST
IPC: D04B7/26
Filed: 1988-04-22
Abstract: In a process for processing the knitting yarn along the edge of a knitted article and/or at the transition of one knitted article to another during the manufacture of knitted articles composed of yarns of different types and/or colours in a flat knitting machine, the knitting yarns (26-29) which pass through the thread guides are cut when the type or colour of the yarn is changed. The knitting yarn which leads directly or indirectly from the end of the last row of stitches of a region of the knitted article to the laterally offset thread guide is held back when knitting is resumed on a region of the knitted article following the first and at a certain distance from the latter, in front of the first row of stitches and in the same plane. When several stitches in this new row have been knitted, the thread is cut at a very short distance from this first row of stitches. The process and construction are thereby considerably simplified and the space requirements are appreciably reduced.

Abstract: A process for manufacturing uniform silver halide grains, which comprises the steps of:
     (A) providing a mixer vessel and a reactor vessel, the mixer vessel being separate from the reactor vessel and the reactor vessel having contained therein an aqueous protective colloid solution and in which silver halide grains are grown;   (B) feeding an aqueous water-soluble silver salt solution, an aqueous water-soluble halide solution and an aqueous protective colloid solution into the mixer vessel;   (C) forming a fine silver halide grain-containing solution by mixing the thus fed solutions in the mixer vessel;   (D) immediately feeding the thus formed fine silver halide grain-containing solution into the reactor vessel; and   (E) stirring said solution in the reactor vessel to grow uniform silver halide grains therein. By prohibiting the addition of the silver ions and the halide ions to the reactor vesselin the form of aqueous solutions, and the addition of the aqueous protective colloid solution containing the silver halide grains from the reactor vessel to the mixer vessel, formation and growth of uniform silver halide grains is achieved. An apparatus for performing the process of the present invention is also disclosed herein.

Abstract: The sieve grid (5) has a sieve bottom (7) which consists of grid bars (9) and which can be arranged horizontally or at a slight inclination. The sieve grid (5) has a cleaning car (25) which executes a to-and-fro motion between the discharge side (21) and the inlet side (22). The cleaning car (25) has two bogies (26), between which a cleaning rake (27) with a rake ridge (28) and fixed teeth (30) is mounted. The teeth (30) have a shallow flank (35) towards the inlet side (22) and a steep flank (34) towards the discharge side (21). The result is that, when moving towards the inlet side (22), solids lying on the grid bars (9) are lifted by the shallow flank (34) and eventually displaced by the flow, whereas, when moving towards the discharge side (21), the steep flank (34) pushes the solids in front and into a discharge shaft (20). Because of the small moving masses of the cleaning car (25) and the teeth (30) always penetrating between the grid bars (9), the clearing speed can be increased, whereby the clearing performance of the sieve grid (5) is also improved. <IMAGE>

Abstract: In an encoder device which is for use in combination with a decoder device in a communication system and which encodes a sequence of digital speech signals into a sequence of output signals by the use of a spectrum parameter and pitch parameters, a primary pulse producing unit calculates a first set of prediction excitation multipulses by the use of the spectrum parameter and the pitch parameters with respect to a preselected one of subframes which result from dividing every frames and produces the first set of prediction excitation multipulses and a sequence of primary synthesized signals specified by the first set of prediction excitation multipulses and the spectrum parameter and the pitch parameters. A subtracter subtracts the primary synthesized signals from the digital speech signals and produces a sequence of difference signals representative of differences between the primary synthesized signals and the digital speech signals. Supplied with the difference signals, a secondary pulse producing unit calculates a predetermined number of secondary excitation multipulses by the use of the spectrum parameter and the pitch parameters. 
     Alternatively, the encoder device may comprise a periodicity detector supplied with the spectrum   parameter for detecting whether or not periodicity of an impulse response of a synthesis filter determined by the spectrum parameter is higher than a predetermined threshold level. The periodicity detector produces a weighting signal representative of a weighted value when the periodicity is higher than the predetermined threshold level. The spectrum parameter is weighted on production of the weighted signals.

Abstract: A device for dispensing a liquid (16), including a container (10) having an interior space (12) accommodating the liquid, a first valve (24, 76, 92, 96, 100, 136, 140, 156) attached to the container, a delivery path (36, 38, 40, 52, 54, 56) having one end submerged in the liquid and extending through the container such that the other end is outside the container, and a second valve (34) disposed in the delivery path for closing and opening the delivery path. The first valve permits a pressurized gas to flow therethrough into the container to raise the pressure within the container, but inhibits a discharge flow of the pressurized gas and the liquid therethrough out of the interior space. The liquid is delivered out of the container through the delivery path, due to the raised pressure within the interior space. The device has a micro-porous membrane filter disposed in a portion of the delivery path which is located upstream of the second valve, as viewed in the direction of delivery of the liquid. The micro-porous membrane filter removes microorganisms from the liquid delivered from the delivery path.

Abstract: Le système de vidéo synchronisation décrit sert à cadencer un détecteur de formation d'image et à cadencer un moniteur vidéo aval et un codeur de système NTSC. A cause des retards de traitement des signaux entre le détecteur et le moniteur/codeur, la synchronisation cadencée du premier pixel produit par le détecteur commence avant le début des trames du moniteur et des codeurs, cette avance étant égale au retard de traitement des signaux. Ainsi, le premier pixel produit par le détecteur est affiché au début des trames vidéo. En réponse à un signal vidéo provenant d'une source externe, le moniteur et le codeur NTSC sont réglés de façon à être synchrones avec la source externe. Le réglage de la synchronisation du détecteur est facilité par le fait que le temps d'avance de synchronisation cadencée des détecteurs est inchangé, que le signal vidéo externe soit présent ou pas.
