Abstract: An arrangement for forming a block in a cable against transmission of fluid along the cable comprises a generally flat blocking array (l) that is formed from a fusible polymeric sealant, e.g. a hot-melt adhesive or a thermosetting adhesive, which has a number of passageways 2 extending from one end of the array to the other end for receiving wires 4 of the cable. The assembly includes a heat-shrinkable covering that can be positioned around the blocking array l in its flat configuration and recovered about the array by applica­tion of heat, and the sealant is capable of melting during recovery of the covering and being forced from a generally flat configuration to a generally cylindrical one by recovery of the covering. 
     The invention also includes arrays  per   se  which may be formed from hot-melt adhesives or thermosetting adhesives. The arrangement enables moisture blocks to be formed relatively rapidly and reliably in cables and harnesses having a large number of wires, and is par­ticularly suitable for use in the manufacture of har­nesses for automotive applications.
Patent EP-0262779-A1 (EP)
Inventor: CHEUNG PETER WING-POON
IPC: A61B5/00
Filed: 1987-08-17
Abstract: Under the present invention, a method and apparatus are provided for compensating for the effect temperature variations have on the wavelength of light emitted by the oximeter sensor light sources (40, 42). In pulse oximetry, LEDs (40, 42) are typically employed to expose tissue to light at two different wavelengths. The light illuminating the tissue is received by a detector (38) where signals proportional to the intensity of light are produced. These signals are then processed by the oximeter circuitry to produce an indication of oxygen saturation. Because current oximetry techniques are dependent upon the wavelengths of light emitted by the LEDs (40, 42), the wavelengths must be known. Even when predetermined combinations of LEDs (40, 42) having relatively precise wavelengths are employed, variations in the wavelength of light emitted may result. Because the sensor (12) may be exposed to a significant range of temperatures while in use, the effect of temperature on the wavelengths may be significant. To compensate for this effect, a temperature sensor (50) is included in the sensor (12) to produce a signal indicative of sensor temperature. This signal is interpreted by the oximeter circuitry including, for example, a microcomputer (16), where the effect of temperature on wavelength is compensated for. In a preferred arrangement, this compensation takes the form of a computation of an alternative calibration curve from which the oxygen saturation is indicated, given a particular processing of signals from the detector (38).

Abstract: La capacité de visualisation d'images d'un lecteur d'images immobiles vidéo est améliorée par la mise en tampon d'un canal vulnérable par lequel les instructions du téléspectateur sont introduites dans le lecteur. Les instructions ordinaires du téléspectateur passent par un canal d'entrée relativement direct (7, 24, 26, 30) reliant un clavier (6) et un dispositif de mémorisation à distance (5), ce canal étant néanmoins défini et protégé par un programme strict de mise en forme des données (10). La mise en valeur d'images implique d'ordinaire un accès difficile et non structuré au dispositif de mémorisation (5) par l'intermédiaire de ce canal, court-circuitant le programme de mise en forme (10) facilement utilisable par l'usager et portant atteinte à des programmes préparés dans le dispositif de mémorisation à distance (5). En interposant un compilateur (40) externe dans ce canal lorsqu'on déclenche une mise en valeur, on peut générer des visualisations d'images spéciales sans mettre en danger l'intégrité du lecteur. Le compilateur externe (40) est relié, par l'intermédiaire d'un processeur externe (44), à une entrée d'interface (50) sur le lecteur. Des programmes d'images spéciales sont téléchargés dans le dispositif de mémorisation (5) par l'intermédiaire de l'entrée (50) et, une fois mémorisés, exécutés indépendamment du processeur externe (44) sous la direction d'un interpréteur (67) dans le lecteur.

Abstract: In a method of making thermoplastic hollow articles, especially bellows, use is made of a blow mould (1) which has two halves, the parting plane of which runs through the longitudinal axis (7) of the hollow article and which can be moved apart and together in the radial direction. A preform is placed in the blow mould (1) and is expanded by means of internal pressure. The blow mould (1) has at least one transverse parting plane (3a; 3b; 3c; 3d; 3e), which runs transversely with respect to the parting plane running through the longitudinal axis (7). The preform (6) placed in the blow mould (1) is expanded with the blow mould (1) in the axially moved-apart state. The blow mould is subsequently moved together in the opposite axial direction, until the blow-mould segments (1a; 1b; 1c; 1d; 1e; 1f) are in contact with one another in the transverse parting plane (3a) or in the transverse parting planes (3a; 3b; 3c; 3d; 3e). <IMAGE>

Abstract: Via a driving profile, the tool interacts with a sliding surface (21a) of the drill hole (11g), the radial clearing feed of the undercutting member (16g) being produced in the wake of the axial working pressure on the revolving tool. During the undercutting operation, the axis (15g) of the tool moves from its initial position in which it is at a distance from the drill-hole axis into an end position in which it lies approximately in the drill-hole axis. The driving profile is formed by the end face of a separate driving element embedded in the shank (14g) and projecting axially from the latter. A bearing body (25g) forming the sliding surface can be inserted into the drill hole (11g) if required while being centred. Consequently, the tool can be used in extremely hard rock or concrete in percussion-drilling operation and also in soft rock in drilling operation. In addition, the fundamental preconditions exist for the production of undercuts of different configuration so that adaptation to structures of different nature and hardness is possible (Figs. 20, 21) <IMAGE>

Abstract: In a waste gas treating method wherein waste gas is treated by adding ammonia thereto and irradiating this waste gas with electron beams, the adhesion of a by-product to the inner wall of a duct (9) is inhibited by feeding the waste gas after irradiation with electron beams at a flow velocity of 10m/sec or less, more preferably 5 m/sec or less, until it at least reaches a first by-product collector (11). The duct may have a rectangular cross-sectional configuration. Thus, it is possible to inhibit increase in the pressure loss of the waste gas being treated and enable stable operation of the waste gas treating process.

Abstract: A method of producing a laminated foam article having permanent, pliable, decorative embossed lines or patterns which produce a relief-like article such as an embossed seat cushion or the like comprises the steps of coating the surface of a foam layer with an adhesive, placing a sheet or layer of cover material on the adhesive-coated foam layer surface, and compressing the covered foam layer with a die having heated projections such that regions of the foam layer adjacent the hot die melt to form embossed lines which are permanent yet pliable. Since the embossed lines are actually collapsed, melted regions of the foam layer, thick, high density foam layers may be embossed. In another aspect, a trilaminate structure is fabricated by additionally bonding a backing layer to the side of the foam layer opposite that to which the cover material is bonded. In one embodiment, the adhesive is cured during the embossing step by the heat from a heated platen and press.
