Title: Stabilization of cemented back fill areas for mines
Inventor: SHERIDAN JOHN P
IPC: E02D3/00
Filed: 1990-02-26
Abstract: This invention provides a method of stabilizing cemented back fill areas for mines. After certain mining operations have been carried out, creating mined voids, it is common to back fill for purposes of stabilizing the rock conditions in the areas where the mining operations have taken place. Generally, the back filling comprises "cementing" which is in fact placing concrete made using the coarse broken rock fraction from the mine tailings. The concrete is pumped or dumped or otherwise put into place, usually without any use of reinforcing steel bars or other reinforcement. By the present invention, additional very large aggregate pieces are placed in the back fill area at the same time as the concrete is pumped or dumped into that area. Those additional very large aggregate pieces are generally at least portions of used automotive tires, or they may be whole tires or shredded tires, or other large pieces of waste rubber material.  It has been determined that the use of such very large aggregate pieces in cemented back fill increases the stabilization of the back fill, thereby assuring stabilization of rock conditions in the mined area where the back fill has been placed.

Patent CA-2023493-A1 (CA)
Inventor: MOROI MASAMI
IPC: A61K9/46
Filed: 1990-08-17
Abstract: A composition for foaming preparation comprising (a) an organic acid of which the crystal surface is coated with a sugar and (b) a carbonate, is disclosed. In the composition, the organic acid is completely shut off from the carbonate by a sugar coating so that the acid does not react with the carbonate over a prolonged storage time. When the composition is put into the mouth, the sugar which covers the acid is readily dissolved, allowing the acid and the carbonate to react and to generate carbon dioxide gas. An excellent foaming calcium preparation can be produced by using calcium carbonate as the carbonate or by adding other salts of calcium to the composition. Such a calcium preparation gives a good taste and favorable feeling upon administration. It is especially suitable for regular administration of calcium over an extended period of time.

Abstract: A  system  and  method  are  provided  for  use  in conjunction with a computer graphics system such that a single pass,  or set of operations can be used to draw specific  polygons  contained  within  an  image  being displayed.   The  computer  graphics  system  includes  a multiple bit frame buffer, a write mask which can disable at least two bits of the frame buffer, a z-buffer capable of being turned off and a color map which is loaded with a background,  a visible line and a hidden line color. With the z-buffer turned off, and the first bit plane of the frame buffer enabled and the second bit plane of the frame buffer disabled by the write mask, the hidden line color is selected from color map 10 and draws the polygon being considered with the selected color.  The z-buffer is then turned on and with one bit plane disabled and another  bit  plane  enabled  by  the  write  mask,  the background color is selected from the color map.   The polygon interior is then drawn with the background color previously selected, however any pixels corresponding to previously drawn  lines  will  not be painted with the background color because of the disablement of bit plane one.  The visible line color is then selected from the color map and the polygon being considered is drawn. With the z-buffer turned on, any visible lines will take precedence over corresponding hidden lines or background colors having corresponding pixels.  The next polygon to be considered is drawn using the same steps as previously discussed.
