Title: Dielectric recording medium and a method of making a record
IPC: B41M5/24
Filed: 1980-02-20
Granted: 1983-04-27
Abstract: A multi-layer information recording medium for storing large amounts of information in a prescribed pattern of microscopic pits, formed by focusing onto the medium a beam of radiation having a prescribed wavelength and having an intensity modulated by the information to be recorded. The record medium includes a substrate having a light-reflective surface on its upper side, a light-absorptive dielectric layer overlaying the substrate and having a thickness approximately equal to an odd integral multiple of one fourth the wavelength of the beam of radiation in the dielectric material, and a thin metallic layer overlaying the dielectric layer and having a light-reflective surface on its lower side. During recording of the information, a substantial proportion of the intensity-modulated beam of radiation is transmitted through the metallic layer to the dielectric layer where it is confined, due to multiple internal reflections by the light-reflective surfaces of the substrate and the metallic layer, until it is finally absorbed by the dielectric material. This causes an evaporation of the dielectric material whenever the intensity of the beam exceeds a predetermined threshold, such evaporation carrying away the overlaying portions of the metallic layer and creating the prescribed pattern of microscopic information-bearing pits.

Title: Video player/recorder for recording on a blank disk and method for home recording
IPC: G11B21/10
Filed: 1980-07-02
Granted: 1984-03-07
Abstract: A blank disc (12) for a home video player/recorder has two or more reference tracks (41, 42) that are formed with the precision of a factory record and under the controlled environmental conditions of disc replication in a factory. When the disc is loaded into the player/recorder for a write operation, the player/recorder reads the reference tracks and simultaneously samples the track error signal and stores the error signal values in the data store of a processor. During the actual write operation, the processor operates on the stored values to generate a control signal to position the write head to define a track that follows the shape of the two adjacent reference tracks in proportion to the spacing of the track (40) between the reference tracks. Thus the player/recorder follows the precision factory reference tracks in spite of track distortion that usually occurs in a home redorder and in a home recording environment, and the track distortion of the home recorded disc is limited to about the track distortion of a factory recording.

IPC: D04H1/732
Filed: 1982-12-27
Granted: 1986-03-26
Abstract: The invention concerns the improvement of the fiber distribution in a web or mat, the attenuation of the fibers being effected by means of gas currents. The material delivered in the form of filaments is attenuated in a channel between two gas jets. At the outlet of the channel, the gas current carrying the fibers entrains the ambient air and passes through a guide apparatus containing two walls. The circulation of the air induced between the channel and the guide apparatus is modified by the interposition of baffles. The modification provides for improvement in the uniformity in the fiber web being made.

Granted: 1988-09-07
Abstract: A coated metallic article, such as a high strength steel, that exhibits low hydrogen embrittlement carries an electrodeposited coating having a microstructure characterized by a plurality of interconnected escape channels that extend from the coating-substrate interface to the surface of the coating. Determining the presence of the escape channels as well as other microstructural features enables one to readily monitor and control plating processes to assure the production of articles that exhibit low hydrogen embrittlement. Low hydrogen embrittlement characteristics are also linked to the amount of residual hydrogen in the substrate after plating and subsequent heat treatment.

Abstract: A method and a device for the anaerobic digestion of organic waste material such as manure in liquid condition include bringing the waste material in an acidification space (17) with a roof (5) collecting gas generated thereby and one or more openings (6, 36) below said roof giving access from said space to a methane fermentation space (18) so that the gas below the roof (5) pushes the liquid to said latter space. A discharge of gas (8, 40) from below said roof (5) to the outside allows liquid to flow back through said openings (6, 36) into the acidification space (17). Below said roof (5) there may be a separate wall (3, 37) defining a hydrolysis space (16), into which the waste material is fed (at 2, 39) before flowing to the acidification space (17). The whole of the device or considerable parts of the walls and ducts thereof may be made of flexible gastight material so as to be easily folded or wound up for transport to the site of use as to be inflatable to sustain its operating shape by a higher than atmospheric pressure of the gas therein. The method and the device allow good digestion in a small and simple device of high capacity and low energy demand.

Abstract: The invention relates to a process for preparing a wet granulate suitable for use in manufacturing tablets by compression and compaction thereof. The process comprises first forming an intimate mixture of particulate-solid materials including pharmacologically or like active matter and tabletting aids. Then one predetermines a quantity of granulating fluid needed to convert the entire particulate-solid mixture into a desired moist, coherent, non-pasty mass as known per se but homogenizes part only of the particulate-solid materials, separately from the remainder thereof, with a chosen amount of granulating fluid, that chosen amount being at least 90% by weight of the aforesaid predetermined quantity of granulating fluid, so as to form a substantially-homogeneous slurry wherein the percentage by weight of solids in the slurry, namely:  Total Solids, i.e. both dissolved and undissolved x 100  Total Slurry, i.e. fluids plus total solids is at least about 25% w/w. Thereafter, the remaining part of the particulate-solid material is moistened in the manner of <<wet-granulation>> as known per se but with the thus-prepared slurry (and then as necessary with the balance of the granulating fluid, if any) so as thus to form the desired substantially-uniform, moist, coherent, non-pasty mass ready for granulation.

Abstract: Procédé pour la préparation de chymosine par lequel une forme insoluble d'un promoteur de chymosine, comme la méthionine-chymosine, est produite par un organisme-hôte comme le Saccharomyces cerevisiae ou l'E.coli, transformée au moyen d'un vecteur comprenant un gène portant le code du promoteur de chymosine, où la forme insoluble du promoteur de chymosine est rendue soluble pour produire une forme native soluble du promoteur de chymosine avant le clivage de la forme native soluble du promoteur de chymosine pour produire de la chymosine. La solubilisation entraîne la dénaturation du promoteur insoluble de chymosine, puis sa renaturation pour donner la forme normale ou native du promoteur de chymosine. On peut ensuite cliver la forme native pour former de la chymosine. On utilise comme dénaturants des solutions aqueuses d'urée ou de chlorhydrate de guanidine et des solutions alcalines avec un pH allant de 9,5 à 11,5; ces solutions sont utilisées soit séparément, soit ensemble. Dans un type particulier de solubilisation décrite, on utilise une solution d'urée ou de chlorhydrate de guanidine pour dénaturer le promoteur insoluble de chymosine. La solution obtenue est ensuite diluée dans une solution alcaline pour produire la forme native du promoteur de chymosine.
