Patent GB-2233677-A (GB)
Title: Preservation treatment of woods
Inventor: BOHO ROBERT
IPC: B27K3/52
Filed: 1989-10-17
Abstract: This invention is concerned with methods for treating wet fir-woods or leaf-woods mainly for reduction of their moisture content and for preservation. The procedure of the invention is conducted in two steps. In the first step, the wet wood is kept in a bath of molten paraffin or a mixture of paraffin with paraffin oil at weight ratios from 90:10 to 10:90 containing 0.05 to 5 percent by weight of colloidal silicon dioxide at 80 DEG  to 180 DEG  C. for 10 to 50 minutes. In the second step, the wood is transferred into another bath of an emulsion consisting of 10 to 30 parts by weight of an aqueous urea/formaldehyde resin with solid content of 30 to 50 percent by weight in term of the solid content of the resin, 0.1 to 0.8 percent by weight of catalyst, 90 to 70 parts by weight of paraffin or a mixture of paraffin with paraffin oil at weight ratios from 90:10 to 10:90, and optionally 1 to 8 parts by weight of additives, preferably emulsifier, pigment, fungicide, and insecticide. The treatment is performed at 60 DEG  to 100 DEG  C. for 20 to 150 minutes. After the wood has been removed and the excess of liquid has drained off, the wood is kept at room temperature for 24 to 48 hours.
Patent GB-2238892-A (GB)
Title: Convolution apparatus
Inventor: DENNIS ANDREW MICHAEL
IPC: G06F17/15
Filed: 1989-12-08
Abstract: Apparatus for determining the result (y0 ... yL+M-1) convolution of a first sequence of L values (x0 ... xL-1) with a second sequence of M values (h0 ... hM-1) operates using the residue number system. Convolution is calculated in parallel in each of R modulus channels by a corresponding forward Number Theoretic Transform/ combing/inverse Number Theoretic Transform calculating means (40) and the results are convened into the required result using a further calculating means (47) which utilises the Chinese Remainder Theorem. In order to provide a check on the correctness or otherwise of the output values of each convolution calculating means (40) each input sequence is augmented by zero values to a length N which is greater than L+M-1 and the forward transforms and inverse transforms are each N-point. At least one point of each inverse transform should in consequence be zero, and respective checking means (50) are provided to check whether this is actually the case. A negative result is used to cause the discarding of the result for the corresponding channel, possibly in favour of the result of a duplicate calculation, or its recalculation. Preferably the point of each inverse transform which should be zero is derived by means of a calculation which employs as respective terms the calculated values of all the potentially non-zero points of the relevant transform. <IMAGE>

Title: Reinforced articles
Inventor: SMYTH MATTHEW
IPC: B29C65/00
Filed: 1990-01-10
Abstract: The present invention relates to methods for reinforcing articles formed from sheet materials such as plastics and fibreglass materials. Essentially the reinforcing method comprises forming reinforcing projections 4, which extend out from the surface of the sheet material, by pinching together two adjacent areas 5,6 of the sheet material 1 between gaps 3 of movable moulds 2, attaching those two adjacent areas to each other by known means such as with adhesives or by chemical bonding. Conventionally sheet materials are reinforced by attaching separate projecting ribs or reinforcements to the sheet material whereas in the present invention the reinforcement is formed from the sheet material itself and forms an integral part of the sheet material. The present invention is particularly useful for use in sheet materials used in the building industry e.g. in the cladding of buildings, walls of buildings, curtain walling and roofs.   Strips of metal may be inserted between or on either side of areas 5,6 as additional reinforcements. <IMAGE>

Title: Desulphurizing flue gas with calcium salts
Inventor: MIURA YOSHIMASA
IPC: B01D53/50
Filed: 1990-07-19
Abstract: A furnace desulfurization process uses a desulfurizing agent in a furnace or flue to absorb SO2 from the exhaust gas. The agent may be a salt obtained by a least partly neutralizing a Ca desulfurizing agent with an acid. A Ca desulfurizing agent can be used to effect a first-stage desulfurization reaction. Ash collected from the exhaust gas and containing a waste of the agent having an unreacted substance enclosed therein can be reacted with an acid to at least partly neturalize the unreacted portion of the agent. Ash containing the resulting salt is recycled to effect a second-stage desulfurization reaction. A denitrating reducing agent can be added to the collected ash, to effect a denitration reaction when recycled.
