Title: Method and apparatus for testing relative permeability of materials
Inventor: SCHUPACK MORRIS
IPC: G01N15/08
Filed: 1989-11-22
Abstract: ABSTRACT        An    apparatus    for    tasting  the   relative permeability    of   materials,   particularly   concrete structures,    comprises    a    transparent,   optically non-distorting  head having a gasket, which together with the  head  defines  a  head chamber, and which allows the head  to  be  sealed against the structure when a partial vacuum  is  induced in the head chamber. The decay of the vacuum  may  be  measured, and the rate of decay provides an  index of permeability, A liquid may be applied to the surface   being   tested   and   will   foam   to   allow identification  of cracks and fissures. In an alternative embodiment,  a  fluid  is  introduced  into  a  secondary chamber  defined  by a secondary gasket and the head, and the  rate  of  permeation of the fluid into the structure provides  a  measure  of permeability. The vacuum mounted test  apparatus  allows in-situ testing without requiring the  extraction  of  sample  cores  from the structure or making   invasive  attachments  to  the  structure,  thus providing  a  quality  control  apparatus  and method for rapid testing of construction materials.

Abstract: Highly accurate, reliable optical character recognition is afforded by a layered network having several layers of constrained feature detection wherein each layer of constrained feature detection includes a plurality of constrained feature maps and a corresponding plurality of feature reduction maps. Each feature reduction map is connected to only one constrained feature map in the same layer for undersampling that constrained feature map. Units in each constrained feature map of the first constrained feature detection layer respond as a function of a corresponding kernel and of different portions of the pixel image of the character captured in a receptive field associated with the unit. Units in each feature map of the second constrained feature detection layer respond as a function of a corresponding kernel and of different portions of an individual feature reduction map or a combination of several feature reduction maps in the first constrained feature detection layer as captured in a receptive field of the unit. The feature reduction maps of the second constrained feature detection layer are fully connected to each unit in the final character classification layer. Kernels are automatically learned by constrained back propagation during network initialization or training.

Abstract: ABSTRACT OF THE DISCLOSURE        A weather strip to be attached along a door opening of a body of a motor vehicle has a base portion and a tubular sealing portion projecting from an outer surface of the base portion.  The tubular sealing portion has a folded end portion which is formed by pressing so as to bond and close an end of the tubular sealing portion.  The folded end portion has a nearly L-shaped cross section, and is composed of a bonded portion which covers the base portion, and a flange-shaped portion which nearly perpendicularly extends from one side of the bonded portion.  The side surface of the flange-shaped portion is a projection of the side surface of the unfolded tubular sealing portion, which faces the body surface of the motor vehicle when the weather strip is attached to the motor vehicle.  The width of the sealing portion is essentially uniform over the entire length thereof from its unfolded tubular portion to its folded end portion so that the sealing portion makes a smooth transition from its unfolded tubular portion to its folded end portion without any sudden change in shape, whereby the appearance of the overall weather strip is improved.
