Abstract: WASTE DUMP COMPRISING A STORAGE SPACE WITH IMPERMEABLE        WALL OF MATERIAL WITH POZZOLANIC PROPERTIES                           Abstract A waste dump (1) for waste material (8) consisting of a partially underground tank (2) having rigid hydraulically set walls (3) with self-restoring capacity when cracks (5) occur in said walls.    The walls may consist of rigid concrete having on their inner side a self-restoring layer (4) when cracks occur, but the walls may also completely consist of such a self-restoring layer.    The self-restoring capacity of the layer and wall respectively is obtained by the presence of still hydraulically settable material with pozzolanic properties in said hydraulically set layer and/or wall.    The self-restoring layer is formed from ground granulated blast furnace slag with fine or coarse blast furnace slag granulate, the ground blast furnace slag may be partially replaced with ground fly ash and the coarse or fine blast furnace may be replaced with gravel.    The tank (2) may also be covered by a rigid cover (7) having the above-mentioned self-restoring properties ob-tained by means of materials with pozzolanic properties.

Title: Method and apparatus for realtime asbestos aerosol monitoring
Inventor: LILIENFELD PEDRO
IPC: G01N15/02
Filed: 1989-10-25
Abstract: ABSTRACT OF THE DISCLOSURE        A real time asbestos aerosol monitor and method are provided.  An ambient air sample is passed through a first sensing zone where fibers in the sample are electrically aligned and oscillated as they are illuminated perpendicular to the fiber axes with high intensity laser light.  The scattered light signal pulse train from a first detector is analyzed to determine the presence and size of fibers in the sample.  The air sample is then passed through a second sensing zone including a hybrid electric/magnetic field to electrically align and magnetically oscillate asbestos fibers.  The sample in the second sensing zone is illuminated perpendicular to the fiber axes, with the scattered light signal pulse train from a second detector being analyzed to determine whether each fiber detected in the first sensing zone is an asbestos fiber.          Advantageously, clean air is circulated across illumination optical surfaces to protect against abrasive elements in the air sample.  Zeroing and calibration are also provided.

Title: Calibrating lasers for optical recording using a maximal readback signal amplitude as a criterion
Inventor: FINKELSTEIN BLAIR I
IPC: G11B7/125
Filed: 1991-02-25
Abstract: A magnetooptic recorder uses a magnetooptic disk for any predetermined number of radially inward tracks which are designated as calibration tracks.  One of the calibration tracks  is selected as  a  laser calibration track.  The selected track is high powered erased and a test pattern is written on the track.  A test pattern is repeated at diverse levels of laser recording power.  A test pattern preferably  includes  or  is  limited  to  the  highest frequency to be recorded in the ensuing data recordings. The recorded test pattern is read back with the readback signal amplitude being envelope indicated and detected. A table of signal envelope values is created in a digital computer. The values then are fit to a curve using second order polynomial curve fitting techniques.  The maximal readback signal amplitude is then selected from the curve corresponding to laser write power used to obtain that maximum  signal  amplitude  and  is  then  selected  as  a criteria for indicating the laser write power as well as the erase write power.
