Title: Sanitary article capable to improve fit against the body and method and apparatus for manufacturing same
Inventor: BRISEBOIS HENRI
IPC: A61F13/15
Filed: 1996-12-11
Abstract: An absorbent structure, such as a sanitary napkin, having abody facing liquid acquisition layer and a garment facing fluidly adaptive component capable of continuously and simultaneously dynamically conforming or adapting the liquid acquisition layer to the body of the wearer in response to pressure. The fluidly adaptive component is filled with a fluid in an amount such that when pressure is applied to the surface of a first portion of the fluidly adaptive component, a volume of fluid is transferred to a second portion of the fluidly adaptive component and causes the surface of the second portion of the fluidly adaptive component to bulge or expand. The fluidly adaptive component is fluid impervious and is adjacent to and in dynamically responsive contact with the liquid-acquisition layer. In a preferred embodiment, the fluidly adaptive component further comprises a barrier layer wherein two superposed fluid impermeable layers define a sealed fluidly adaptive component between them.  The fluidly adaptive components of the present invention, when incorporated into an absorbent structure, dynamically urge a portion of the body-facing liquid-acquisition layer toward the body of the user.

Title: Mixer for mixing of liquids or suspensions and method for mixing
Inventor: HILLSTROEM ANDERS
IPC: B01F27/91
Filed: 1995-10-23
Abstract: A mixer for liquid or suspensions comprises two mixing chambers (2, 3) provided each with an outer inlet (10, 12). The chambers are connected to each other in such a way that the first chamber (2) leads to the second chamber (3). A number of mixing elements (6, 7) are arranged on a rotating axis (5) which is common for the two chambers. The mixing elements have different shapes in the two chambers. In the first chamber (2) the mixing elements are arranged to achieve a mixing by means of large shear forces.    In the second chamber the mixing elements are arranged to achieve a mixing by stirring mainly without shear forces. A method for continuous mixing comprises mixing a little amount of a first liquid with a considerably larger amount of a second liquid in a first mixing chamber in which the mixing takes place by way of high shear forces. The obtained mixture is subjected to mixing by stirring mainly without shear forces in a second mixing chamber.

Patent CA-2208385-A1 (CA)
Title: Cart loader and method of loading
Inventor: MYERS HUGH I
IPC: B65G47/88
Filed: 1997-06-20
Abstract: The present invention comprises a cart loading machine that provides for improved operating efficiencies, and includes a cart loading station, an infeed conveyor, a pattern forming area, a carrier sheet and wiping mechanism, and a fork loading apparatus. The cart loading station includes a framework defining a cart loading position and a cart waiting position. With the carrier in its extended position having carried a fully formed pattern to the cart loading position, a wiping mechanism is extended from beneath the carrier plate to contact the bundles as they sit on the carrier so that then the carrier moves back to its retracted position, the bundles are blocked and stripped therefrom. The wiping mechanism is then retracted below the carrier to permit the loading of a subsequent pattern of bundles thereon. This wiping mechanism eliminates the need for an overhanging blocking mechanism thereby permitting more efficient loader design and easier access to the pattern forming and bundle stripping areas.

Title: Method of roof control in an underground mine
Inventor: GUO SONG
IPC: E21C39/00
Filed: 1996-06-07
Abstract: Stresses in an underground mine are determined by analyzing mechanical properties of mine site stratum (Figure 1, numerals 2, 4, 6 and 8) including orthotropic properties of at least one of Young's modules and Poisson's ratio. The mechanical properties of the mine site are combined with a physical layout of the mine that includes one or more of an entry and a pillar arrangement formed in a stratum of material being mined (Figure 1, numeral 10). The physical layout may also include an array of roof bolts in a roof of the mine. A finite element analysis (FEA) (Figure 2) is performed on the combined mechanical properties and physical layout to obtain a stress analysis of the mine site. The stress analysis is analyzed to determine if the layout of the mine is sufficient to provide a desired degree of support while maximizing the removal of material being mined. If the desired degree of support is not provided, the physical layout and/or the array of roof bolts is adjusted and subsequent FEA performed until the desired degree of support is provided.

Title: Speaker recognition device
Inventor: HATTORI HIROAKI
IPC: G10L17/10
Filed: 1998-01-27
Abstract: A speaker recognition device for judging whether or not an unknown speaker is an authentic registered speaker himself/herself executes 'text verification using speaker independent speech recognition and 'speaker verification by comparison with a reference pattern of a password of a registered speaker'. A presentation section instructs the unknown speaker to input an ID and utter a specified text designated by a text generation section and a password. The 'text verification' of the specified text is executed by a text verification section, and the 'speaker verification' of the password is executed by a similarity calculation section.      A judgment section judges that the unknown speaker is the authentic registered speaker himself/herself if both the results of the 'text verification' and the 'speaker verification' are affirmative. According to the device, the 'text verification' is executed using a set of speaker independent reference patterns, and the 'speaker verification' is executed using speaker reference patterns of passwords of registered speakers, thus considerably reducing storage capacity required for storing reference patterns for verification. Preferably, 'speaker identity verifi-cation' between the specified text and the password is executed.
