IPC: H04L29/10
Filed: 1993-03-29
Abstract: A system of managing memory used by communications tasks of a communications network operating with a multi-layered communications protocol, Specially formatted buffers are used to contain data to be passed down the protocol stack of a source node, across a communications link, and up the protocol stack of a destination node. before entering the source stack, message data is presegmented so that each buffer contains only so much message data as may be transmitted as a single data unit from source to destination, even after all layers of the source stack have added layer headers to that portion.      Then, when the buffers axe being passed within the source stack, any layer may segment the message data by simply unlinking buffers and adding its layer header to each segment. Inter-layer data passing is by means of exclusive access to buffers by one layer at a time. At the source stack, any layer that must send multiple copies of the message data may checkpoint the buffers and thereby regain the same buffers. At the destination stack, the buffers may be reassembled by relinking them.

Abstract: Calcium salts, such as calcium acetate, calcium formate or calcium propionate, are obtained from aqueous liquors derived from the pyrolysis of lignocellulosic biomass containing cellulose, hemicelluloses or starch.  The above biomass is subjected to rapid pyrolysis to obtain a crude product containing an aqueous phase and an organic phase.  The product obtained, preferably as the aqueous phase, is then distilled to produce a distillate containing at least one acid selected from acetic acid, formic acid and propionic acid as well as their esters and formaldehyde.  An alkaline source of calcium is added to this distillate to adjust the pH to an alkaline level sufficient to hydrolyze the esters, cause at least partial oxidation of the formaldehyde and prevent volatilization of acetate, formate or propionate ions as acetic acid, formic acid or propionic acid respectively.  This pH adjusted alkaline liquid is then subjected to a further distillation to remove water and volatile organic components and produce at least one of calcium acetate, calcium formate and calcium propionate as solid residue.

Filed: 1994-05-24
Abstract: A three-dimensional model of the teeth of a patient is prepared by taking molded impressions of the mandibular and maxillar teeth, placing separately the impressions on a support table define an X-Y plane and detecting the Z distance from a probe by directing a beam of laser light onto the impression and calculating from the pattern of reflected light a centre of the light falling on an area array. The scanning in the X-Y plane is effected continuously and is limited by datum points defining a dental arch. The impression is then tilted and the process repeated and information correlated to provide the three-dimensional model. A partial impression is then taken of both mandibular and maxillar teeth in comparison with datum points to provide information concerning the bite (occlusal) positions of the teeth.   This information is then compared with the full impression to simulate using the digital images movement of the jaw from an open position to the bite (occlusal) position.

Abstract: A acetylating agent vapor is brought into contact with a material containing cellulose while continuously moving the acetylating agent, and thereby, the material containing cellulose is acetylated in a vapor phase.  Solvents for dilution, catalysts, and an immersion process in an acetylating agent (liquid) are not necessary, and thereby, it is not merely the case that the process is simplified, but the acetylation period is shortened as a result of the increase in reaction efficiency, and the accumulation of excess heat of reaction in the material containing cellulose during the reaction is prevented, and thereby, the uniformity of acetylation is improved.  Furthermore, in the present invention, wooden strips acetylated by this method are accumulated and modified wood is manufactured.  This modified wood has superior resistance to moisture, possesses no acetic acid odor, and does not cause rusting.
