Patent EP-0347035-A2 (EP)
Inventor: PALERMO THOMAS J
IPC: A61B19/00
Filed: 1989-04-27
Abstract: A guidewire system (12) for use in catheter exchanges avoids the need for a separate exchange wire (20) by connecting an extension wire (30) to the proximal end of the guidewire thereby increasing the effective length of the guidewire to permit a catheter exchange. The proximal end of the guidewire is attached to the distal end of the exchange wire by a disconnectable reattachable connection which avoids deformation of the connected joint.

Abstract: A method of molding a foamed product is carried out by using a front and a rear mold (31, 32) for molding a front and a rear portion of the foamed product and a core (33) interposed between the front and rear molds. The method includes steps of pouring or spraying one of foaming stock solutions (41, 42) onto a molding surface of the one mold, arranging the core in the one mold and pouring or spraying the other foaming stock solution onto the core or a molding surface of the other mold. The front and rear molds are suitably closed at a moment of time 30-100% of a rise time of the foaming stock solution applied last. Thereafter the closed molds are maintained in a position where an angle of the closed molds relative to a horizontal plane is suitably within a range from 90° to an angle more than 0°. The front and rear molds are pivotally connected to each other with their one ends by means of a pivot shaft (35). The core is pivotally supported, with its one end by a shaft (37) arranged in parallel to the pivot shaft.

Abstract: A process for the production of demercurized synthesis gas, reducing gas or fuel gas. Mercury-containing fossil fuels e.g. coal were reacted by partial oxidation to produce gaseous mixtures comprising H₂, CO, H₂O, CO₂, H₂S, COS, entrained slag and/or ash, mercury vapor, and optionally CH₄, NH₃, N₂ and Ar. Unexpectedly, the mercury vapor was produced in the reaction zone; and it was found to be thermodynamically stable even in the presence of H₂S under the strong reducing conditions that prevailed in the gas generator. No new sulfides of mercury were formed. The mercury vapors were removed from the main body of the process gas stream in a pressurized solvent scrubber at a relatively low temperature. By this means, the mercury vapor was condensed and simultaneously the mercury and sulfur contents of the clean process gas stream were reduced to low levels. In one embodiment, the last vestiges of mercury were removed from the demercurized product gas stream by carbon sorption.

Abstract: The invention relates to a segmented sabot for a low-calibre elongate kinetic-energy projectile. As a measure to increase the bending resistance of a sabot segment, it is known to have longitudinal ribs extending between the front guide flange and rear pressure flange. …<??>However, longitudinal ribs of this type do not contribute appreciably to the transmission of shearing forces from the sabot into the circumference of the projectile body during the acceleration phase in the barrel and for production reasons can be produced only in numerous successive cost-intensive manufacturing steps. …<??>The sabot (60) according to the invention, whilst further reducing the dead-load fraction, is intended to increase the bending resistance, at the same time allowing for as cost-effective a mass production as possible. This is achieved by means of the invention in that the total cross-section (50) of the sabot (60), at least in part regions (36, 24) of its longitudinal extension, has an essentially polygonal cross-sectional shape (72, 72'). …<??>This allows a hitherto unattained cost-effective cutting machining, for example by means of simple cylindrical milling cutters. …<IMAGE>…

Title: Sound attenuator
Inventor: NOGUCHI YOSHIHIRO C O MITSUBIS
IPC: F24F13/02
Filed: 1990-07-14
Abstract: A sound attenuator has at least one sound absorber composed of a hollow body of a hard porous material and an outer or inner layer of air, and exhibits good sound-absorbing property even in a low frequency range, even if the hollow body has a small wall thickness. The hollow body may be provided with projections or a semicircular or otherwise shaped part or parts, or both serving to maintain the outer or inner layer of air in proper shape. The device is inexpensive and yet is very reliable in quality. When the device is long, the projections in linear form are particularly useful for restraining any flanking transmission of noise and thereby enabling the device to achieve a higher rate of attenuation per unit length. The sound-absorbing property of the device can be controlled over a wide range of frequencies if the hollow body has a specific gravity varying continuously in a specific direction. The device exhibits an improved sound-absorbing property particularly in a low frequency range if the hollow body is provided with a skin layer on its wall surface facing an air passage.

Abstract: After a yarn interruption and a subsequent restoration of the yarn connection at the winding station of a textile machine, the yarn has to be transferred into its normal yarn running position on the yarn guide of the winding station. But the transfer of the yarn usually does not take place in synchronism with the movement of the yarn guide, and therefore the yarn may be deposited at one and the same point on the bobbin for some time. The thick places occurring thereby can lead to difficulties in the unwinding of cross-wound bobbins. 
<??>It is proposed so to coordinate the movement of the transferring yarn and the traversing movement of the yarn guide with one another that, for the yarn transfer, the yarn and the yarn guide arrive essentially simultaneously at the transfer point of the yarn. The exact transfer of the yarn to the yarn guide is obtained by means (34, 35, 36) for monitoring the feed movement of the yarn (5b) to the transfer point and means (42, 43) for monitoring the traversing movement of the yarn guide (11), which are connected to control devices (33, 39).

Abstract: In sauna cabins, heat is supplied at least in part through the introduction of steam, where the quantity of steam to be introduced is regulated depending on the internal room temperature in order to prevent overheating. Since the required temperature is maintained over a longer period in modern, well-insulated sauna cabins, steam is supplied at relatively long intervals so that the "visible" steam first disappears and then, as a result of condensation, the steam content of the air also decreases. Through the introduction of a fluid coolant, preferably dependent on the vapour density inside the room, a state of temperature equilibrium can be obtained and a visible steam atmosphere simultaneously maintained. <IMAGE>
