Patent EP-0315338-B1 (EP)
IPC: A61F2/46
Filed: 1988-10-19
Granted: 1993-02-03
Abstract: Surgical instrumentation and a method for cutting bones on one or both sides of a joint such as the knee joint to allow the application of a joint prosthesis. A rod (10) is inserted into the medullary canal of the bone to be cut. The rod (10) is secured within the medullary canal and a router guide (14) is mounted on the rod (10) for rotation thereabout while being restrained against movement axially of the rod (10). A router or side cutting drill (16) is inserted through the router guide (14) into contact with the rod (10) and actuated to rotate about its own axis. The router guide (14) and the router (16) are then caused to rotate about the rod (10) to thereby cut the bone to produce a substantially planar surface thereon suitable to bear against a joint prosthesis.

Title: Method and apparatus for treating fiber suspension
IPC: D21D5/02
Filed: 1988-10-31
Granted: 1992-03-11
Abstract: The present invention relates to a method and apparatus for treating fiber suspension. The method and apparatus in accordance with the present invention is especially suitable for treating the fiber suspensions of the wood processing industry, for example, in thickening or washing pulp. The methods and apparatuses in accordance with prior art techniques have recently been based on using vacuum filters. In other words, the separation of liquid from the pulp has been based on the fact that an underpressure has been arranged on one side of the pulp cake, whereby the external atmospheric pressure has displaced liquid in the pulp. Thereby air has passed into the pulp causing slime problems among other things. On the other hand, a drawback with such apparatus has been their poor ability to utilize the filter surface, because only 50 - 60 % of the total filter surface area has even under the best conditions being efficiently used. The method and apparatus in accordance with the present invention enables the use of almost the whole filter surface by arranging the pressurized feed of the pulp to the apparatus, whereby liquid is separated due the lower pressure, for example the normal atmospheric pressure prevailing behind the filter surface. On the other hand, the discharge of the pulp cake has been arranged to be carried out from only a very limited portion of the filter surface, whereby the use of the filter surface area is even further intensified.

Title: Process for precipitating chromium and/or vanadium from sulphuric acid waste
IPC: C01B17/90
Filed: 1988-04-26
Granted: 1991-02-27
Abstract: The concentration of sulphuric acid waste from the manufacture of titanium dioxide is increased by evaporation from 65 to 70 %. It is aged for several days, during which time the metals dissolved in the acid are generally precipitated in sufficient quantity, with exception of chromium and vanadium. In order to precipitate the chromium in a sufficient quantity in a sufficiently short time, 0.3 % by weight of aluminum is added to the evaporated acid waste. The aluminum has an active surface and is obtained shortly before addition by machining, size reduction or comminution. The strongly negative redox potential of this aluminum gives rise to chromium of obviously lower valency, whose salts are less soluble than those of the higher-valency chromium or metallic chromium, and which can be precipitated more easily.

Abstract: In the manufacture of multilayer garment parts composed of outer fabric cuttings and an interlining, one of the outer fabric cuttings is usually attached to the interlining by a seam and the second outer fabric cutting is then stitched to both. The bonding unit so formed is then turned, bonded and pressed. This known manufacturing cycle is unsuited to the automation sought after by the invention. According to the invention, both outer fabric cuttings and at least one interlining are assembled before bonding in a processing unit which is transferred after bonding to a magazine arranged downstream of the bonding press. This process and the device for implementing it are particularly suited to the manufacture of cuffs and collars.

Abstract: Selective bromination of alkylarenes to the alpha monobrominated derivative is desirable as a precursor for the selective production of, for example, the corresponding alcohols. The product can be obtained by a photolytic reaction between the substrate, hydrogen peroxide and hydrogen bromide in approximately equimolar ratios in an organic solvent, but improvement in the yield of the product coupled with similar or improved selectivity in its production was either not achieved or was actually impaired by a range of variations in the ratios and by omitting the solvent. The invention employs mole ratios of H2O2:substrate of 0.1:1 to 0.4:1, preferably 0.2:1 to 0.33:1 and of H2O2:bromide of 1:1.2 to 1:2, preferably about 1:1.3 to 1:1.8 and progressive introduction of the H2O2, either in the presence or absence of the solvent, whilst irradiating with light preferably having principal emmisions in the range of 250 to 600 nm, and the process thereby achieves either or both of improved yield and improved selectivity of the alpha monobrominated product. The reaction mixture is preferably maintained at 50 to 70 DEG C. The process is especially suitable for deactivated alkylarenes, such as o-nitrotoluene.

La chute d'alimentation s'étend dans un logement du terminal et communique avec une gorge d'aplatissement. La gorge d'aplatissement a une largeur plus petite que celle de la chute d'alimentation pour aplatir la poutre à profil en W. Un organe de pliage est également prévu dans le terminal pour plier le rail de protection suivant un arc curviligne dans le sens opposé à la direction de l'impact du véhicule. Un ancrage de câble est monmté de manière libérable sur le rail de protection. Un câble s'étend à partir de l'ancrage jusqu'à un premier poteau situé à l'extrémité du rail de protection. L'ancrage de câble comprend des oreilles pour détacher l'ancrage du rail de protection lorsqu'il entre dans le terminal d'extrusion avec l'ancrage de câble. Pour empêcher la rotation des poteaux qui tiennent leur rails de protection lorsque le terminal d'extrusion et le véhicule d'impact descendent le rail de protection lors d'une collision, un câble au niveau du sol s'étend au travers de trous percés dans chaque poteau.

Cette couche de dilatation (18) est liée à la carte de circuits imprimés (20) sauf aux endroits (40) situés au-dessous de la place occupée par le support intermédiaire (13) et les brasures (42). Cette couche de dilatation permet une dilatation tolérable entre le support intermédiaire en céramique plat (13) et la carte de circuits imprimés (20) par suite de la différence de dilatation thermique, pour ainsi réduire le fissurage des brasures (42). Dans une variante d'exécution, une mince couche de polytétrafluoroéthylène (PTFE) (39) empêche la liaison au-dessous de la place occupée par le support intermédiaire.

Abstract: A memory system which is shared by a plurality of requestors each of which supply read and write address bits to the memory system is read out of, or written into, in accordance with read and write address bits. A sequencer is utilized to initiate a sequence of timing signals that control the reading, writing and partial writing of data. Certain ones of these signals occur at fixed intervals from the receipt of an initial load address signal. A read address circuit coupled to receive the read address bits generates a set of check bits. A read address stack means stores each set of read address check bits upon the occurrence of an associated load read address stack signal. A write address check bit generator means is coupled to receive write address bits and to generate a set of check bits representative of the write address bits. A write address stack means stores each set of the write address check bits upon the occurrence of an associated load write address stack signal. A read address stack selector and a write address stack selector read out read address check bits and write address check bits, while the sequencer controls the transmission of the read address check bits and the write address check bits to an error detection circuit.
