Abstract: A smoking product having an improved flavor is prepared by applying a naturally occurring terpenoid glycoside sweetener to the portion of the product that is intended to be contacted by the smoker's lips.

Abstract: A smoking article which delivers to a smoker during each puff a flowstream having a higher concentration of smoke during the first portion of the puff and a lower concentration of smoke during the remainder of the puff.

Abstract: A color picture tube having a cathodoluminescent screen, electron gun and a slit type apertured mask located between the screen and gun, wherein the slits in such mask are arranged in columns and the slits in each column are separated by webs, has an improved web configuration. Alternate webs within a column are of lesser thickness than the general mask thickness with the geometric center of the alternate webs being offset toward the screen side of the mask.

Abstract: A video playback system utilizing a vertically moving strip of photosensitive film on which linear bit fields containing a pulse-code modulated (PCM) representation of a television picture have been recorded. The system includes an illuminating means which successively scans a horizontal line of bit fields. Magnifying optics include a linear multiple lens array and a correction lens assembly. As each bit field in the line is successively illuminated, the magnifying optics project an image of the bit field to a linear detector array. Digital information from each bit field is transferred to a buffer; the digital information is converted to analog video signals and applied to the input of a video utilization device. Vertical registration is accomplished by detecting servo information recorded on the film and optically slaving the film drive system to the scanning operation.

Abstract: Addition of substituted pyrrole compounds to tobacco to enhance the flavor and/or aroma thereof.

Abstract: A data recording and retrieval system wherein a beam of coherent radiation is optically formed into an intense spot and deflected by first and second deflecting means to impinge upon a storage medium. The beam is spot-focused by a lens system which includes a multiple lens array, and selectively deflected by a pair of mirrors through a particular lenslet of the multiple-lens array to one of a plurality of storage fields of the recording medium. When the storage field is selected, a second deflection system produces a randomly selectable X-Y deflection of the beam, within the area of the preselected storage field. The multiple lens array provides a plurality of lenslets, each lenslet of the array corresponding with a different one of the plurality of storage fields within a storage area of the recording medium.
