Abstract: A modular floor sub-structure is provided wherein discrete floor modules having bottom surfaces and sides extending upwardly to support paired floor tile are interconnected to sit upon a floor surface and, in turn, support rack-mounted computer components. Select ones of the floor modules contain air cooling coils and blowers, while others are provided with uninterrupted power supplies and still others retain power distribution networks. The cooling system of a given module as well as the UPS components of another given module are provided having a capacity for supporting one computer component. Where more than one computer component is to be supported by the system, then additional modules are provided to develop an expanded elevated floor surface with power and heat removal servicing specific to each computer component. A step arrangement is provided, the interior of which is utilized to retain flexible chilled water conduits for servicing the cooling coils within adjacently disposed floor modules as well as for providing servicing access to the cooling coils, thh UPS system and a poer distribution console. The step structure pivots from a seated to an open position to provide service access.

Abstract: The invention concerns a method for application of an adhesive or equivalent onto a moving material web, wherein the adhesive is applied by means of at least one applicator device (20) through at least one nozzle (30) onto the face of the material web to constitute an adhesive strip (G) in the longitudinal direction of the material web (W).  In the method, the material web (W) is made to run at an invariable distance from the nozzle (30) end placed next to the material web (W).  The adhesive is passed onto the material web (W) through the nozzle (30) in the  applicator head (31) of the applicator device (20), and the applicator head (31) and the nozzle (30) for the adhesive are washed for the next cycle of use in a container space (23) in the applicator device (20).  Further, the invention concerns a device for application of an adhesive or equivalent onto a moving material web (W), which device (20) comprises frame constructions (21, 22, 23), an adhesive-applicator head (31), a container spaced (23), and at least one adhesive nozzle (30).  The applicator head (31) is provided with a support face (38) or support faces (34, 35), over which the material web (W) is passed so that the adhesive nozzle (30) is placed at a invariable distance from the material web (W).  The device (20) comprises means (32, 33, 34) for transferring the applicator head (31) into the container space (23) and means (24) for washing same.

Abstract: A coater incorporates a die (42), a reservoir (46), a gravure cylinder (48), and a doctor blade (50) for applying coating fluid to a moving surface (44). The flow rate of coating fluid to the gravure cylinder (48) is controlled to equal the rate at which coating fluid is consumed by the coating process. This eliminates the need to recycle surplus coating fluid. The coating fluid can be quickly and conveniently replaced with a solvent in the reservoir (46) when coating is not being performed to reduce the occurence of coating defects arising from excessive evaporation of solvent and premature solidification of coating fluid.

Abstract: A label sheet assembly for transparent paper labels has a substantially transparent paper label sheet (20) with a substantially transparent, pressure sensitive adhesive coating (42). Labels (22) are die cut out of the paper label sheet (20). The paper label sheet (20) is mounted on a backing sheet (28), which has a release coating to allow removal of the labels. The pressure sensitive adhesive (42) may be stable in the presence of temperature up to 200 degrees Fahrenheit so that the labels may be printed in a laser printer. The label sheet assembly may be printed in its entirety by an ink jet printer or xerographic printer with a resulting high print quality. A method for printing transparent label sheet assemblies comprises forming double thickness label sheet assemblies, creating a paper supply (48), feeding label sheet assemblies from the paper supply through xerographic (50), laser and ink jet printers (52), removing labels (22) from a backing sheet (28), and applying the labels to products to be labeled. By using transparent paper labels, this method allows a single source (48) of transparent label sheet assemblies to supply a variety of different printers, including ink jet, laser, and xerographic printers.

Abstract: An airbag module and mounting. An inflator is received within the cushion, such that the cushion wraps around the back side of the inflator. The inflator includes an extending fastener, and possibly an extending tab. The inflator, or the tab, is partially retained by a receiving structure on the seat. The fastener extends through another section of the seat, such that securing the fastener secures the entire inflator. Additionally, since the cushion surrounds the inflator, the cushion is also secured. To maintain the cushion in the folded condition, a frangible wrap extends around the cushion and inflator. Upon inflation, the frangible wrap, and the seat covering, are torn by the expanding cushion to permit further expansion. This arrangement eliminates the need for a protective housing for the inflator and cushion. Other mounting arrangements are also provided.

Abstract: L'invention concerne un circuit de multiplication numérique pour multiplier un signal numérique SN par une forme d'onde périodique, en principe sinusoïdale. Ce circuit utilise un générateur numérique (10) de phase périodique .PHI. variant en dent de scie, et il utilise une approximation de s échantillons d'une fonction Ksin.PHI. par des sommes algébriques de puissances entières positives de deux pour chaque valeur de phase, K étant un coefficient identique pour toutes les valeurs de phase. Le produit de SN par ces sommes algébriques est rapide, simple à réaliser et ne nécessite pas une table de sinus. Un décodeur (12) recevant la phase .PHI. définit les puissances de deux à établir, et un circuit d'aiguillage (14) effectue les multiplications par des puissances de deux sous la commande du décodeur. Un ou deux additionneurs (ADD1, ADD2) établissent les sommes de puissances de deux. Le résultat est une valeur approchée du produit SN.K.sin.PHI..
