Patent CA-2356718-A1 (CA)
Inventor: BLUNDELL C CHRISTOPHER
IPC: F04C15/00
Filed: 2001-08-30
Abstract: The progressing cavity pump or motor stator has a generally constant liner thickness, by contrast with prior art pumps having very large liner thickness variations.  The pump or motor stator is made by first coating a helicoidal mandrel with at least one liner material to define a liner of generally constant thickness; then placing the liner-coated mandrel in a housing; then placing a liquid (or liquid containing solids) intermediate material between the liner and the housing, the intermediate material being of a type which can then be solidified; then so solidifying the intermediate material to bond it to the liner and the housing; and then retracting the mandrel, leaving the liner in place bonded to the intermediate material. The liner adheres strongly to the intermediate material, but only weakly to the mandrel, such that out-rotating the mandrel readily separates it from the liner, leaving the liner in place.

The optical storage media is pre-formatted with tracks (74) to precisely locate the recorded microscopic data spots (71). Groups of these microscopic data spots (71) form data bars which in turn form data pixels (72, 73, 82, 83) whose dimensions are at least four times greater linearly and 16 times greater in area than the microscopic data spots (71). The data pixels (72, 73, 82, 83) can be read with photodetector arrays such as CCD arrays.

Abstract: The invention concerns a method of foaming steel-making slags, wherein calcium nitrate is added to the slag alone or together with carbon. Calcium nitrate and carbon can be fed into the slag trough chutes or trough lances with injection gases such as air, nitrogen, carbon dioxide or inert gases. The solid components can be injected separately or with the same lance as a mixture or injected as pre-fused granules. For ladle slag foaming, calcium nitrate and carbon is added from above the melt. It is preferred to use a ratio between calcium nitrate and carbon in the range from 4.1 to 2:1. For foaming of stainless steel slag, it is preferred to add FeSi, Al or Mg before calcium nitrate and carbon is added or injected into the slag by an injection gas. Air, nitrogen, carbon dioxide or inert gases can be used as injection gas. The invention also concerns the use of calcium nitrate as a foaming agent for steel-makings slags. The invention can be used for slag foaming in electric arc furnaces and ladles.
