Abstract: A method of producing stone-set jewelry includes the step of forming at least one affixation-groove (15) within the stone (10) to be set in the jewelry. A stone to be set with the present method should have an upper and a lower portion which is at least substantially entirely hidden from view when the upper portion of the stone is viewed. In accordance with the present method the affixation-groove (15) should be formed in the lower portion (16) of the stone such that it too is hidden from view when the upper portion of the stone is viewed. The method also includes the deposition of a mounting material within the affixation-groove by applying a conventional casting method. Finally, any excess deposited mounting material can be removed and the stone affixed to the article of jewelry via the mounting material such that the mounting material of a completed article of jewelry is not visible when the stone is viewed from the upper portion thereof. New articles of jewelry formed from the methods of producing jewelry are also disclosed. <IMAGE>

Abstract: A data compression method and system that include the substitution of a substring of data characters located at a first position in a stream of data characters with a substitution code. The substitution code includes a reference to a previous position in the stream of data characters at which is located a substring of data characters that matches the substring of data characters which are being substituted located at the first position. The substitution code also includes an indication of the size of the substituted substring. The reference in the substitution code is a backwards offset to the previous position relative to the first position. According to a further aspect, Huffman encoding can be applied to the backward offsets, the substring lengths, the consecutive literal character lengths, and the literal characters themselves to reduce the data requirement size. In an application of the data compression method to geographic data that has been organized to facilitate access and use by a navigation application program, the Huffman tree(s) for decoding the encoded characters are stored in a separate portion of the database from portions that include the data that have been compressed using the Huffman coding, thereby facilitating the use of the same Huffman tree(s) for more than one portion of the data records. <IMAGE>

Abstract: A method and apparatus is provided for inhibiting scaling in an electrodeionization system and, more particularly, for increasing tolerance to hardness in the feed water to an electrodeionization unit by inhibiting precipitation of scale-forming metallic cations contained in the feed water and thereby increasing efficiencies of the electrodeionization system. Water to be purified is passed through an electrodeionization unit in which the flow in the diluting compartment is countercurrent to the flow in the concentrating compartment. This is to impede the migration of scale-forming metallic cations from the diluting compartment, through the cation exchange membrane, into the concentrating compartment and towards the concentrating compartment side of the anion exchange membrane, thereby preventing scale formation on the anion exchange membrane. The electrodeionization unit may be further modified by dividing the concentrating compartments into first and second compartments by a porous diaphragm or ion-conducting membrane. The porous diaphragm or ion-conducting membrane effectively eliminates convective transport of scale-forming metallic cations from the cation exchange membrane side of the concentrating compartment to the anion exchange membrane side of the concentrating compartment, thereby inhibiting scale formation on the anion exchange membrane.

Abstract: Electrochromic coating solutions are prepared by allowing hydrated tungsten oxides to react with an admixture of hydrogen peroxide and an organic acid or anhydride. The intermediate tungsten peroxy acid is esterified by heating under reflux with alcohol to produce a precursor solution including peroxyester tungsten derivatives. The precursor solution can be used to apply a coating to the conductive surface of the substrate by dip coating, spraying or spin coating. The coating is then dried and is heated to a sufficiently high temperature to convert the tungsten peroxyesters to amorphous tungsten oxide with good electrochromic properties.

Abstract: A process for forming a web by aerodynamic method comprises feeding an aerosuspension onto a moving forming wire positioned at an inclination angle  alpha  relative to the aerosuspension flow and removing an air component of the above aerosuspension by means of a suction device located on a backside of the wire, with the incline angle  alpha  being selected by the equation arcctg(Vw/Vf +  2ROOT  eta ) <  alpha  < arcctg(Vw/Vf -  2ROOT  eta ), where: Vw - velocity of forming wire; Vf - air filtration rate through a layer of formed web and wire provided by a suction device at a steady stationary airflow from the aerosuspension into the suction device. As a result, a possible shear of the formed web caused by the aerodynamic pressure of aerosuspension flow is prevented, which permits production of paper having a high degree of uniformity.

Abstract: The proposed seismic zone construction system is essentially based on the following operations: 1. interruption of the continuity between the construction and the underlying foundation-ground complex, by making cuts at the top of the pillars, located between the construction and the foundation-ground complex; 2. insertion into the abovementioned cuts of fixed supports in the earth quiet state (absence of quakes) with the alternative function of mobile multidirectional supports in the earth movement state (quake present). In the event of seismic events, such a system permits the rigid translation of the foundation-ground complex with respect to the construction, which remains virtually still and undeformed under the prevalent action of the weight force. A variant to the abovementioned construction system is also proposed, compared with which it has the further property of spontaneous self-centring when the seismic event ceases. <IMAGE>

Abstract: A space is created in the sausage filling between two adjacent sausages by rotation of a blade (4) mounted diametrically across the sausage machine. The sausage filling machine (1) consists of two concentric tubes (6 and 7). The sausage casing (10) is passed over the outer tube and crimped (11) at one end and filling passed through the inner (6). When enough filling for one sausage has been pushed into the casing the inner tube is rotated by a toothed wheel (13) acting at its upstream end. This also moves a blade (4) mounted at the downstream en d of the inner tube and clears all the filling from a portion of the casing. This allows the crimpers separating two adjacent sausages to be placed on empty sections of casing.
