Title: Method of preparing a sanding block to repair a damaged surface profile
Inventor: TCHERNOV ANDREI
IPC: B24D15/02
Filed: 2002-08-15
Abstract: A method of preparing a sanding block to repair a damaged surface profile. A first step involves finding an undamaged surface profile that matches the damaged surface profile. A second step involves providing a moulding block having a body with a flat surface surrounded by an upstanding flexible peripheral seal to form an enclosure. A third step involves filling the enclosure of the moulding block with hot melt adhesive and, with the hot melt adhesive still mouldable, pressing the moulding block against the undamaged surface profile until the hot melt adhesive solidifies to form a negative image of the undamaged surface profile. A fourth step involves removing the negative image formed of solidified hot melt adhesive from the undamaged surface profile for use as a sanding block.

Title: Process and apparatus for testing multi-layer composites and containers produced therefrom
Inventor: HENNING CARSTEN
IPC: G01N27/26
Filed: 2001-12-13
Abstract: The invention relates to a process and an apparatus for detecting gas-permeable damaged points in an electrically non-conductive layer which can exist as a single layer or as a multi-layer composite with at least one conductive layer.     A test subject is disposed in a test chamber. On the one side of the layer which is to be examined is an electrically-conductive layer, and on its other side is a gas environment. The gas in the gas environment is ionised at a given pressure by means of an electrical discharge. A counter-electrode disposed in the test chamber forms a test current circuit, together with a voltage source and a measuring device.  If the layer which is to be tested contains a damaged point, a distinct current is measured in the test current circuit, if the gas discharge is maintained, which serves as an indicator for a damaged point.   The process allows the detection of damaged points which are fluid-tight, or which are only present in a non-conductive layer in the case of a multi-layer composite.     The process is used in the case of containers for sensitive pharmacological preparations if rigid requirements are placed on these containers with regard to their integrity during storage times or periods of use which extend over a plurality of months
Patent CA-2435003-A1 (CA)
Inventor: NYGAARD RICHARD A JR
IPC: H04L1/24
Filed: 2003-07-07
Abstract: Once an eye diagram measurement is begun and there is an eve diagram displayed, different on-screen measurement tools may be used singly, or in combination. Each measurement involves indicating with cursors and line segments regions of the eye diagram that are of interest, and a parameter or parameters associated with each measurement tool in use is reported in a (usually) separate area of the display. An Eye Limits measurement allows the specification of a point within an eye diagram, whereupon it finds and reports the eye diagram coordinates first encountered along horizontal and vertical lines extended from the selected point (i.e., "eye opening" size).  The coordinates of the point itself are also reported. A Four Point Box measurement allows the construction on the eye diagram of a rectangle having sides parallel to the coordinate axes of the eye diagram.  The coordinates of the rectangle are reported, as well as information about the number of points on the eye diagram that occur on or within the rectangle. A Six Point Box and a Diamond may be defined and used in a like fashion. A Slope Tool uses two end points to define an intervening line segment, whose slope and location can be adjusted to match some region of interest on the eye diagram. The pertinent information about the line segment and its end points is then reported. A Histogram measurement may be performed on any selected slice of the eye diagram. The histogram is thus of a distribution of number of hits versus either time axis location at a fixed voltage, or voltage at a fixed time location.  Duplicate cursors appear on both the line defining the slice and within the histogram. Either cursor can be grabbed and moved, which then also moves the other. The scale for the number of hits for either histogram may be either linear or logarithmic.
