Abstract: Molecular sieve compositions are prepared by extracting aluminium and substituting chromium and/or tin for extracted aluminium to give molecular sieve products containing framework chromium and/or tin atoms. The process of preparing the chromium and/or tin-containing molecular sieves involves contacting a starting molecular sieve with a solution or slurry of at least one of a fluoro salt of chromium or a fluoro salt of tin under effective process conditions to provide for aluminium extraction and substitution of chromium and/or tin. 
     Generally, the product molecular sieve has a unit molecular formula of (M w Al x Si y )O 2   
where "M" is at least one of chromium or tin; and "w" "x" and "y" represent that mole fractions of "M", aluminium and silicon, respectively, present as framework tetrahedral oxide units, said mole fractions being such that they are within the triagonal area defined by points A, B, and C of Figure 13, having the following parameters:

Abstract: A pad of sheets each including a layer of flexible polymeric material having a coating of repositionable pressure sensitive adhesive on a second end portion while being free of adhesive along a visually distinctive first end portion in a stack with adjacent ends of the sheets aligned and with the first and second ends of successive sheets adjacent. The stack can be disposed in a chamber partially defined by a top wall having a slot through which the first end portion of the uppermost sheet projects. Relative movement is afforded between the top wall and the uppermost sheet to afford, as the uppermost sheet is pulled through the slot, alignment of the slot with successive portions of the uppermost sheet towards its second end as those successive portions are peeled from the stack. In a final relative position between the top wall and the uppermost sheet the slot is along the second end portion of that sheet and the first end portion of the underlying sheet to cause movement of the first end portion of the underlying sheet through the slot with the second end portion of the uppermost sheet to leave the first end portion of the underlying sheet projecting through the slot after the uppermost sheet is removed.

Abstract: This invention is concerned with pitch shift apparatus for converting an audio signal into PCM digital data and then making a pitch shift, wherein the PCM digital data is written in a ring memory (2) by a write address generator circuit (3), and read therefrom by two read address generator circuits (4, 5) which start to read at time points differing by an amount corresponding to 1/2 the ring memory (2) at a certain pitch, in which case immediately before the read address on the now finally outputting side and the write address causes passing or cyclic delay, the read address on the switching-to side is stopped from increasing during the interval from a time point at which an audio signal on the switching-to side makes zero crossing to a time at which an audio signal on the now outputting side makes in-phase zero crossing, and switching is made at the zero crossing point, so that the connection of the audio signals can be smoothly made without such AM modulated component as caused in the cross fade method, enabling high-quality pitch shift to be achieved.
