Title: Sealing ring
IPC: F16J15/32
Filed: 1978-07-26
Abstract: A double toric sealing ring for providing a seal between a casing and a butterfly member of a butterfly valve is formed with two helical springs each forming a torus and disposed concentrically. The helical spring forming the outer torus has a coil diameter greater than that of the coils of the spring forming the inner torus. Each spring is enclosed by a respective sheath. A metal annulus extending between the tori has its radially inner and outer peripheries bent around the respective sheathed tori. The radially extending portion of the annulus between these bent parts is formed with a bellows like groove concentric with the tori, to permit deformation of the sealing ring which in use is mounted in the butterfly valve so that the smaller diameter encased torus provides a seal between relatively stationary parts and the larger diameter encased torus provides a seal between the casing and the movable butterfly member when the latter is closed.

Patent ES-8104150-A1 (ES)
Title: Electric forehearth and method of melting therein
IPC: H05B3/00
Filed: 1980-05-13
Abstract: Disclosed is a method and apparatus for preventing the formation of blisters in an electrically-heated forehearth that utilizes submerged electrodes connected to either a single or plural phase alternating current source. The electrodes are arranged so that Joule effect heating is effected by passing alternating current through the molten glass with the center tap of the secondary of the power transformer being connected to the positive side of a Direct Current source through a filter, while the negative side of the DC source is connected to a counter electrode, immersed in the glass at a point upstream of the forehearth. With this physical arrangement, the formation of blisters due to free electrons migrating to and collecting on some of the electrodes that are at different potentials than the others is prevented. This is accomplished by the fact that all of the forehearth electrodes are maintained at the same potential and the counter electrode is at a different potential so that these free electrons will collect at the single counter electrode and create bubbles or blisters at a position well in advance of the forehearth. With this system, the blisters will disappear before reaching the forehearth. The forehearth electrodes are disclosed as being formed of stainless steel with molybdenum tips and the electrode support being electrically isolated from the forehearth structure.

Title: Cuvette for the optical examination of fluids.
IPC: G01N21/03
Filed: 1980-05-27
Abstract: A cuvette for holding a liquid to be examined optically has front, back, and side walls defining a rectangular cross section and a Y-shaped structure at the bottom thereof for holding the liquid. The Y-shaped structure extends between transparent front and back walls with an upper funnel mouth extending to the side walls, and a liquid holding portion formed of inner walls spaced between the side walls, and extending down to a rounded, tub-shaped bottom. The front walls are transparent and serve also to form the front and back of the liquid holding portion. The bottom preferably has a frustroconic surface to minimize the amount of liquid required for examination and to facilitate mixing of liquids added to the cuvette. The side walls extend below the tub-shaped bottom, and are joined to the front and back wall midway up the liquid holding portion by means of a rib, so that light is not scattered by the side walls and optical inhomogeneities are prevented.
Patent ES-8407234-A1 (ES)
Title: Radiation shield ring assembly and method of disassembling components of a nuclear steam generator using such assembly
IPC: F22B37/58
Filed: 1980-06-27
Abstract: This invention provides shielded access to the irradiated heat exchanger tube bundle of a nuclear steam generator contained within a cask after removal from the generator. This tube bundle must be reduced in size and confined for removal from the containment building through hatchways of generally limited size. Access to the enclosed bundle is at the flanged joints of adjacent sections forming the cask and which are vertically separated to permit an oxygen lance to be inserted therein for burning the tubes at that level. A rotatably supported annular seal ring covers the separation and shields against the escape of radiation or irradiated material during the burning process. The ring provides access ports through which roller supports are mounted on the cask and provide access of the cutting tool to the tubes. Rotation of the ring on the rollers permits the tool to be inserted completely around the cask. After the tubes within one section of the cask are severed, the tubes and that portion of the cask are removed and the ring raised to a next position where the procedure is repeated.

Title: Transmission ratio variators
IPC: F16H9/10
Filed: 1981-09-09
Abstract: A transmission ratio varying arrangement involves establishing transmission between a drive shaft and a driven shaft by two orbital systems, one for each shaft, and including gear wheels which move concentric to the respective shafts thereof. One orbital system is joined to the other by simple or composite conventional transmission elements, the radius of each orbit being variable simultaneously, maintaining the sum thereof constant. Each of the shafts is provided with an identical truncated thickening which is in direct position and which, acting as a wedge, contacts radial supports which are guided in holes made in a sleeve which is equally spaced from the holes and which is provided at its outer part with peripheral wings perpendicular to the shaft. The wings are provided with radial notches in which there are guided the shafts on which there rest the gear wheels which move when the thickened shaft and the sleeve turn in unison joined by keys. The shafts of the wheels are disposed on forks between the arms of which are radial supports which, through the holes of the sleeve, contact the truncated thickening of the shaft. Each shaft is displaceable in an opposite direction with respect to the other shaft, proportionally varying the radius of contact of the radial supports in one shaft with respect to the other, by maintaining the sum of both radii constant.
