Title: A collector container for reuseable waste materials
Inventor: REILING BERNHARD
IPC: B66C1/66
Filed: 1992-11-04
Abstract: ABSTRACT   A collecting container for recyclable waste materials, in particular glass, is composed of partial containers (1, 2, 3) with closed outer, upper and lower sides (4, 5, 6), with the exception of top waste-introduction openings (7), and of at least one open inner side that faces the other partial container in the closed position of the container. The partial containers further have hinges (14) at their top sides (6) that mutually link them, as well as coupling means (17) spaced apart from the hinge axis in the direction of the side opposite to the other partial container. The partial containers may be swung open by means or the coupling means (17) that cooperate with a hoist provided with complementary coupling means, so that their open inner sides are separated, forming a downwardly oriented emptying opening. In order to provide such collecting containers with two or more partial containers that may be independently emptied in any desired order, the partial containers (1, 2, 3) are arranged with their top hinges (14) on a central receiving body (15) having wall sections that close the open inner sides of the partial containers in their respective closed positions.

Title: Magnetic resonance imaging using pattern recognition
Inventor: SMITH JUSTIN P
IPC: G01R33/58
Filed: 1993-05-13
Abstract: An MRI technique in which the similarity of samples from different portions of a body is determined and displayed.      In one embodiment, the method can be used to track the spread of a known primary tumor to other portions of a patient's body.      The MRI apparatus is used to produce a training set comprising one or more training samples. The training set is formed from a plurality of congruent first images of a training region of the body. Each first image is produced using an MRI pulse se-quence different from the pulse sequences used to produce the other first images. Each first image comprises an array of pixels; and each training sample comprises a spatially aligned set of pixels from each first image. The same technique is used to pro-duce a plurality of test samples corresponding to a test region of the same body. The test samples are produced using the same pulse sequences as the training samples. The training and test samples are then compared, to produce similarity data indicat-ing, for each test sample, the degree of similarity between the test sample and the training samples. A display is then generated based upon the similarity data.

Title: Unidirectionally stretchable elastomeric trilaminate and method for its manufacture
Inventor: COSLETT W ANDREW
IPC: A61F13/15
Filed: 1995-05-26
Abstract: An elastomeric trilaminate fabric for use in the waist band or leg cuff of disposable diapers, training pants and other similar products.  The trilaminate has a middle elastomeric web sandwiched between a pair of gatherable inelastic webs.  The elastomeric web may take the form of a scrim or a film made from elastomeric material.   The nonwoven webs are made from staple or bicomponent fibers which have been carded and thermal bonded or spunbond.  During manufacture, the nonwoven webs are ultrasonically pattern bonded to each other while the elastomeric web is in a stretched state.  The elastomeric web is sandwiched between and captured by the bonded gatherable webs.  Upon release of the tension applied to the elastomeric web,  it will relax to an unstretched state.  As the elastomeric web contracts, the nonwoven webs gather between the bonding points. The result is a stretchable laminate which elastically returns to an unstretched state when tension is removed.
