Abstract: The dryer of this invention employs a vacuum chamber interposed below and between first and second heated dryer rolls (26,28). The vacuum chamber has two sides and a top which overlies two grooved reversing rolls (110,114). The vacuum chamber controls all flow of air in the gap between and below the dryer rolls. The dryer-fabric-backed paper web passes from the first dryer roll around the reversing rolls and up to th e second dryer roll. The dryer fabric seals the vacuum chamber, and air is drawn therefrom. The provision of the grooved rolls permits a greater wrap of the felt around the dryers and the application of vacuum to hold the web against the felt during movement of the web between the dryers and the grooved rolls and between the grooved rolls.

Abstract: A preformed, unitary composite for reinforcing while suppressing curl in bituminous roofing membranes includes as a first layer, an open, non-woven grid of low shrinkage, continuous filament polyester yarns that are at low tension and adhesively secured together, and as a second layer, a lightweight, preformed fiberglass mat, the second layer being adhesively secured to one side of the first layer. The adhesive secures the two layers together such that at least some of the individual yarns of the first layer are at least partially coated and impregnated by the adhesive without forming a film that closes all openings through the composite. The adhesive that secures the continuous filament yarns of the first layer together and that secures the first and second layers together is a vulcanizable rubber binder, such as cross-linked styrene butadiene rubber, which includes about 50 to about 80% styrene. The composite is flexible, capable of being impregnated by bituminous material, and sufficiently strong to be useful in reinforcing such membranes. The composite, when used in reinforcing such membranes, suppresses curl in the membrane during and after forming the membrane. Also disclosed is a process for making such a composite.

Abstract: The invention relates to a method in a system using pressurized medium for employing and controlling a hoisting boom assembly particularly in combination with a working machine, the system comprising at least two cylinder-piston mechanisms (1, 2) using pressurized medium, a pressure unit (P) for pressurizing the medium, and a control unit (V) comprising two operating valves (4, 5) and using said cylinder-piston mechanisms (1, 2) by leading pressurized medium to their respective pressure chambers to be filled at a time and, in a corresponding manner, by removing pressurized medium from their respective pressure chambers to be emptied at a time. The method is applied particularly during simultaneous use of the cylinder-piston mechanisms (1, 2) by connecting the cylinder-piston mechanisms (1, 2) to operate in a series so that pressurized medium is conveyed from the pressure chamber of one cylinder-piston mechanism (1 or 2) to be emptied to the pressure chamber of the other cylinder-piston mechanism (2 or 1) to be filled up. The pressurized medium is returned to the control unit (V) from the pressure chamber of the other cylinder-piston mechanism (2 or 1) to be emptied.

Abstract: A method and receiver which provides, among other features, for resubtraction of an already subtracted signal in order to eliminate subtraction errors, termed re-orthogonalization, is described herein.  According to exemplary embodiments, pairwise combinations of spreading codes are used to despread received composite signals. For example, these pairwise combinations can include a first spreading code associated with a signal that has already been subtracted and a second spreading code associated with a signal which is weaker than that associated with the first spreading code. In this way both resubtraction and subtraction are performed at the same time.

Abstract: A shelf mounting support includes an annular flange portion having a side surface from which projects a cavity defining body portion. The mounting support is adapted to extend through an aperture formed in a liner of an appliance with the body portion of the mounting support being inserted in a respective aperture from an outer insulation zone side of the liner. Each mounting support is initially retained in the aperture through the use of an adhesive element that attaches the flange portion of the mounting support to the liner. Thereafter, the liner is positioned within an outer shell of the appliance and foamed insulation is then injected into the insulation zone and into the internal cavity of the mounting support to anchor the mounting support in position. To support a shelf, a plurality of mounting supports are arranged in a common plane upon which the shelf is adapted to rest.

Abstract: A multi-packaging device capable of carrying containers having a range of diameters. The multi-packaging device is constructed from a plastic sheet having an array of apertures arranged in lateral rows and longitudinal ranks. The plastic sheet contains integral segments of a resilient polymer co-extruded with respect to the plastic sheet or laminated on the plastic sheet. The plastic sheet may also contain a longitudinally arranged line of weakness under the resilient polymer. The resultant structure enables the multi-packaging device to maintain integrity when a large diameter container is inserted into an aperture because the resilient polymer laminate continues to stretch even after the plastic sheet reaches a stress level approaching neck-down.
