A sanitary napkin having an absorbent core with three longitudinally oriented trisections, a central trisection flanked by two outboard trisections. The absorbent core is formed of a single layer of tissue. The single layer of tissue is folded on itself to provide a two-ply thickness at each of the outboard trisections and a single thickness at the central trisection. The two plies of the outboard...

In a process of separating a liquid sample having phase portions of different densities by centrifugal separation, a phase separator container is employed. The phase separator container comprises a housing having concentric inner and outer cylindrical walls defining a longitudinal axis and a top wall and further a piston body constituting a bottom wall of the housing. The piston body defines toget...

PURPOSE:To precisely perform automatic operation even in the case where the relation between engine rotating speed at the time of no load and accelera tor actuator stroke has a hysteresis by teaching this relation on the operating side and returning side of an accelerator pedal, and properly use two data. CONSTITUTION:The relation between an engine output torque 5 and an accelerator actuator strok...

The invention is directed to methods for the pretreatment of a lignocellulose-containing biomass. Pretreatment comprises the addition of calcium hydroxide and water to the biomass to form a mixture, and subjecting the mixture to relatively high temperatures for a period of time sufficient to render the biomass amenable to digestion. The pretreated biomass is digested to produce useful products suc...

PURPOSE:To prevent the whitening of images and to obtain a good contrast by heat treating a glass spacer in a reducing atmosphere thereby blackening the glass spacer. CONSTITUTION:The glass spacer is formed of glass contg. at least one component of PbO, TiO2, Sb2O3, As2O3, and Bi2O3 to a fiber or bead shape. This glass spacer is disposed in an electric furnace in which a reducing atmosphere contg....

The device uses a magnetic field produced by a system placed along the direction of the track to be followed. The device comprises two magnetic sensors (2, 3) mounted on the vehicle which receive and detect the field. The system producing the field is a waveguide (1) which, for the determination of any sideways deflection with respect to the direction of the track, is connected to a radio transmit...

A continuous gas fluidized bed process for the polymerization of an olefin monomer, especially ethylene, propylene, or mixtures of these with other alpha-olefins, wherein monomer-containing recycle gas employed to fluidize the bed is cooled to condense out at least some liquid hydrocarbon. The condensed liquid, which can be a monomer or an inert liquid, is separated from the recycle gas and fed di...
