Abstract: A cigarette making machine is provided with a pressure drop measuring unit (1) located at or close to the garniture of the making machine. The pressure drop of a gas stream of constant volume is introduced into the compacted tobacco rod beneath the format finger (2) on the making machine at a point at which that pressure drop measurement correlates with the bound pressure drop of the finished cigarette. The unbound cigarette pressure drop or draw resistance experienced by the smoker can be calculated using the bound tobacco rod pressure drop obtained by correlation with the measured pressure drop across the rod in an algorithim processed by calculation means. The degree of ventilation of the cigarette may also be utilised in the algorithim calculation. Comparator means allows the unbound cigarette pressure drop to be maintained within pre-set limits by varying cigarette parameters which affect the overall unbound cigarette pressure drop. <IMAGE>

Patent CA-2102597-A1 (CA)
Title: Thickened compositions
Inventor: KAGERMEIER SONJA
IPC: A61L2/18
Filed: 1992-05-06
Abstract: Many aqueous compositions containing a peroxygen compound have a very low viscosity and thus easily run off non-horizontal surfaces. Particularly when the peroxygen compound is a soluble peracid, the compositions are difficult to thicken successfully, because many commonly available thickening systems for aqueous media either fail to thicken them or are decomposed and/or decompose the peroxygen compound substantially during storage. The compositions, preferably containing a soluble peracid are thickened with an alkali metal silicate, preferably sodium silicate, such as Na2O.(SiO2)2, suitably in an amount of from about 2 to 6 % of the composition and normally introduced in the form of a concentrated aqueous composition. The compositions may contain additionally an alkylammonium methosulphate. Preferred peracid solutions include dilute equilibrated peracetic acid solutions. The solutions when thickened to form a viscous liquid are suitable for disinfecting hard surfaces and when thickened to form a gel are suitable for suspension in an aqueous medium, for example in block form.

Title: Improved method and apparatus for incrementally stretching a zero strain stretch laminate web to impart elasticity thereto
Inventor: WEBER GERALD M
IPC: B29K21/00
Filed: 1992-01-28
Abstract: An improved method and apparatus for incrementally stretching "zero strain" stretch laminate webs to impart elasticity thereto in the direction of initial stretching, at least up to the point of initial stretching. The "zero strain" stretch laminate material (1) is formed of at least two plies of material (4a, 5, 6) which are either intermittenly or substantially continuously secured to one another along at least a portion of their coextensive surfaces while in a substantially untensioned ("zero strain") condition. One of the plies (4a) is stretchable and elastomeric, while the second ply (5, 6) is elongatable, but not necessarily elastomeric. The sec-ond ply will, upon stretching of the laminate, be at least to a degree permanently elongated so that, upon release of the applied tensile forces, it will not return to its original undistorted configuration.  This results in z-direction bulking of the laminate web when the applied tension is released as well as subsequent elastic extensibility in the direction of initial stretching, at least up to the point of initial stretching. In a particularly preferred embodiment of the present invention the opposed peripheral edge por-tions of the laminate web to be incrementally stretched are subjected to restraint to restraint to substantially prevent inwardly directed slip-page or contraction thereof in a direction parallel to the direction of stretching. This maximizes the effectiveness of the incremen-tal web stretching operation by forcing the "zero strain" stretch laminate web to undergo the fullest possible degree of elongation during the incremental stretching operation.
