Patent CA-2087407-A1 (CA)
Inventor: HANKINS WILLIAM G
IPC: C01B17/54
Filed: 1993-01-15
Abstract: A method for conditioning flue gas to improve the removal of fly ash by an electrostatic precipitator employs a relatively high concentration (4-71/2 %) of SO3 conditioning agent. The SO3 is formed by combusting sulfur and excess air in a sulfur burner to produce a mixture of air and SO2 and converting the SO2 to SO3 in a catalytic converter. The ratio of air to sulfur is maintained constant over a wide range of SO3 production rates, and the air is unheated during most production rates. The mixture of air and SO2 from the sulfur burner is cooled without increasing the volume of the gaseous mixture. <IMAGE>

Title: Securement of liner for shaped charge
Inventor: EKHOLM OLOF
IPC: F42B1/02
Filed: 1993-01-26
Abstract: ABSTRACT OF DISCLOSURE     The present invention relates to a method and an apparatus for securing the inlays, so-called liners (3) which, in the effect direction, define the explosive portion in charges for directed bursting (hollow charge) effect, so-called shaped charges, and which, on detonation of the explosive, are converted into a particle jet or more or less projectile-like so-called slug which accounts for the effect of the charge on the target. The object of the present invention is to solve those problems which occur when materials with excessively different coefficients of thermal expansion must be used in the inlay (3) and a case (1) surrounding the rest of the explosive portion.     According to the present invention, this is solved by a specific securement of the inlay (3) in the form of a specially designed anchorage ring (4) which gives a securement which is rigid in the axial direction, i.e. parallel with the intended effect direction of the charge, but permits certain temperature movements across this direction.

Inventor: OGAWA KEN
IPC: F02D41/34
Filed: 1993-04-27
Abstract: An air-fuel ratio control system for an internal combustion engine calculates an amount of fuel to be supplied to the engine in response to the rotational speed of the engine and a parameter indicative of load on the engine, and an amount of fuel injected into an intake passage and adhering to the inner surface of the intake passage, based upon a direct supply ratio and a carry-off ratio.  A feedback correction value is set to such a value that an air-fuel ratio in exhaust gases from the engine becomes equal to a desired value, and the amount of fuel calculated as above is corrected by the direct supply ratio, the carry-off ratio, and the feedback correction value set as above.  A control speed at which the feedback correction value is corrected is set based upon at least one of the direct supply ratio and the carry-off ratio.

Title: Tear tape
Inventor: THOMAS KENNETH A
IPC: B65D17/46
Filed: 1993-07-06
Abstract: TEAR TAPE ABSTRACT OF THE DISCLOSURE A package includes a paper stock inner layer together with an overwrap of a transparent, tearable polypropylene which is wrapped around the paper stock and heat sealed at seams to provide a moisture impermeable covering for the paper stock package. A tear tape is positioned between the paper stock and the overwrap so that an end tab of the tear tape can be pulled to cause a tear line in the overwrap material. The tear tape is bonded by an adhesive to the inside surface of the overwrap and includes an end tab portion projecting through the seam. The tear tape is formed from polyester but carries on its inside surface a thin layer of a material for example acrylic or PVDC which is compatible with the polypropylene overwrap to form a heat seal therewith while being free from bonding to the paper stock. This prevents moisture loss from the package through the seam at the area of the end pull tab of the tear tape.
