  • Patent number: 5637106
    Abstract: Several embodiments of an improved absorbent insert or core are disclosed. According to one embodiment, the insert comprises a fluff layer physically integrated to at least one layer of laminate consisting of at least one tissue layer and polymer powder secured to it and supported on it. The fluff layer and the laminate are embossed between rollers that physically integrate the two layers and produce transfer sites through which liquid is rapidly transferred into the fluff layer, away from a wearer. In another embodiment, an absorbent insert is produced by embossing a laminate between a smooth roller and a patterned roller and trimming and folding the embossed laminate to produce an insert with a central region with an exposed pattern of embossed depressions and, on each side of the central region, lateral regions with an exposed, smooth surface.

  • Patent number: 5551234
    Abstract: In a process for running an internal combustion engine, especially a marine diesel engine, compressed air is taken to the cylinders by an exhaust gas turbocharger (1). The air is cooled before its introduction into the cylinders. Part of the charge air, however, by-passes the cooler (5). Its quantity is determined so that the charge air temperature behind the cooler (5) for all the charge air is above the dew point and does not exceed the maximum permissible temperature for the engine. It is thus possible to increase the charge air pressure. By-pass line (9) is fitted with a control valve. The charge air cooler is water-cooled. A cooling jacket (12) may be fitted around by-pass line (9).

  • Patent number: 5518186
    Abstract: A voltage block device for use with electrostatic spraying apparatus for conductive coatings is disclosed. The device maintains an air gap which electrically isolates a grounded paint supply from a charged spray head to prevent the leakage of potential to the grounded paint supply. The device comprises a tube made of non-conductive material and having ends which are closed by upper and lower caps to define a closed space which is pressurized. A valve secured in the upper cap delivers paint into the closed space to raise the level of conductive coating material therein to the level of an external sensor. In a first mode of operation, valve interlock circuitry opens the valve when the spray head is not charged and the sensor detects a low level of coating material. The valve closes if the level of conductive coating material in the closed space reaches the external sensor or the spray head becomes charged, restoring an air gap which electrically isolates the grounded paint supply.

  • Patent number: 5493888
    Abstract: Precision forming apparatus is disclosed. The apparatus comprises a die with a cavity which conforms with the shape of a portion of a part to be formed, a punch with a cavity which conforms with the shape of another portion of the part to be formed, and means for causing relative movement of the die and the punch between(a) a first (closed) position in which the die and the punch nearly abut one another and the two cavities are aligned and form a single cavity which conforms with the shape of the part to be formed, andb) a second (open) position in which the die and the punch are separated from one another and a billet can be placed in the cavity of one to be formed, when the two are returned to the first position, to the shape of the single cavity.The cavity forms longitudinally opposed end walls in their entirety. As a consequence, the length of a part to be formed is determined by the punch cavity, and can be changed by substituting a different punch.

  • Patent number: 5468572
    Abstract: A substantially binder-free glass fiber separator, especially for valve regulated ("sealed") lead acid batteries is disclosed. The separator has a reduced thickness and temporarily inhibited resiliency. A substantially binder-free glass fiber web having a given thickness is wetted with a controlled amount of liquid and compressed to a substantially reduced thickness and the liquid suppresses the natural resiliency of the glass fiber separator so that it will have a substantially reduced thickness when the compression is released. The amount of liquid required to suppress the resiliency of the glass fiber separator is substantially less than the minimum amount of the portion of electrolyte which would be carried in the separator in a finished cell.

  • Patent number: 5461819
    Abstract: A lure with outstanding reverse gliding features and unprecedented glide path control features is disclosed. The lure comprises a lure body, a wing, an arm portion which extends upwardly from the wing and a buoyant member which is connected to the upper end of the arm. The arm can be adjusted to control the position of the buoyant member which, in turn, controls the direction of glide, the rate of descent during a glide and the rate of ascent during retrieval. The arm can be adjusted to position the buoyant member in a neutral position where the lure, during gliding, will have a generally straight glide path. The arm can also be adjusted to position the buoyant member in a non-neutral position so that the lure glide path will be generally arcuate.

  • Patent number: 5354289
    Abstract: A capacity monitor for diapers and the like, including super absorbent material disposed in or adjacent to an absorbent core is disclosed. The monitor comprises an indicator and a baffle to prevent direct contact between the absorbent core and the indicator. The indicator is preferably a ribbon of hot melt adhesive with a wetness indicator which changes color when exposed to liquid. The baffle is a substantially water impervious sheet positioned between the absorbent core and the indicator so as to prevent direct contact between them. The diaper and the monitor are constructed so that there is a threshold level of liquid which, when deposited in the diaper, will effect a color change in the indicator. A quantity of liquid which is below the threshold will not effect a color change in the indicator and a quantity of liquid which is above the threshold will effect a color change in the indicator.
