Abstract: A method and apparatus for recovering tobacco from imperfect cigarettes that are ejected downstream of a cigarette-producing machine and are supplied to a recovery apparatus for opening the paper casings and separating the tobacco from the paper pieces and any filters that are present. The imperfect cigarettes of a given cigarette-producing machine are continuously supplied to an in-line recovery apparatus, which has a space-saving configuration, is coordinated to the output of the cigarette-producing machine, and is mounted adjacent thereto. Varying quantities of imperfect cigarettes are collected within the recovery apparatus, which is equipped with a rotary conveyer. A uniform stream of the recovered tobacco is returned to the cigarette-producing machine.

The first channel of the program source includes an audio program comprising a series of spoken words which are audibly reproduced by the console unit and the second channel includes a series of control signals which are operative for actuating lights adjacent prespecified words in the work booklet. The operation of the console unit is coordinated with the audio program so that lights are actuated adjacent to the words in the work booklet as the same words are audibly reproduced by the console unit. One embodiment of the device further includes a plurality of depressible user response buttons on the console unit for indicating responses to questions presented in the audio program.

Abstract: The system consists of a board with sockets and an assortment of tetrahedral pegs having a regular obverse face and a reverse side in the form of a triangular shank that inserts to a matching fit in one of the sockets. When the pegs are inserted into the board or first element the adjacent faces of the pegs make contact so that no gaps exist between adjoining edges. Each of the faces, or a part of each face, if divided into more than one field, is uniformly tinted in one of a set of repeatable colors or polychrome or monochrome shadings.

Abstract: A dispenser comprising a container and a mouthpiece is adapted to deliver a volatilizable liquid orally to the user. A volatilizing chamber is defined between the liquid reservoir in the container and the drawing passage in the mouthpiece through which the user inhales. A permeable fluid barrier separates the liquid in the reservoir from the open pore material which fills the volatilizing chamber and limits the amount of liquid which can be aspirated through the open pore material to the user. A vent passage in parallel with the fluid barrier when uncovered and open allows air to be drawn through the open pore material to volatilize any liquid retained thereon. When covered and closed, the vent passage allows liquid to be aspirated from the reservoir through the permeable fluid barrier, the volatilizing chamber, and the mouth piece and into the user's mouth.

Abstract: A connector body with a first end and a first part thereon and a second end and a first part thereon includes a passageway aligned along an axis passing through the first end and part. Openings in second part permit communication from the first end to the second end since the openings extend from the second end to at least the passageway. A male luer taper located on the first part about the passageway tapers outwardly of the axis from the first end to a annular groove. A luer nut with an internally threaded collar and an apertured flanged portion seats within the groove permitting rotary but not axial movement of the luer nut relative to the taper. A method provides a plurality of connections between openings and a passageway with a connector body having a first end and a first part thereon and a second end and a second part thereon and a passageway through the first part from the first end extends to a plurality of openings in the second part permitting communication.

Abstract: A container for containing an additive material for modifying the characteristics of a smoking article. The container contains at least two components that are movable between a first position and a second position with respect to each other. In the first position the additive material is hermetically sealed inside the container during storage of the smoking article prior to use. The container is activated by moving the components of the container to the second position to provide air flow pathways through the container so that the additive material can modify the smoking article accordingly. The components may have perforations that are covered by cooperating overlapping portions of the components of the container in the first position and uncovered in the second position. Alternately, the container may include a sealed capsule containing the additive that is punctured by moving the components during activation.

Abstract: The consumer color reference kit of this invention is based on the four basic known process printing colors, viz., magenta (red), yellow, cyan (blue) and black, and contains nine major sheets each of which is dividable readily by the user into four minor cards. Each mirror card contains eight separate, different, distinct readily visually discernable color specimens. One of the major sheets, the primary major sheet, contains four shades (tints) of each of eight major colors or color groups, viz., red, orange, yellow, green, blue, purple, brown and gray.The remaining eight major color sheets are referred to as secondary and each secondary major sheet contains thirty-two different, distinct readily discernable shades (tints) of the same eight previously mentioned major colors/color groups.On one side of each of the nine major sheets, the color speciments are glossy (smooth).

Abstract: A self-extinguishing cigarette equipped with fail-safe means for fire prevention and improved means for holding the cigarette. The cigarette is disposed and held within a hollow, perforated tube to which the supply of air is limited. In one embodiment of the invention, a tilt-ring is fastened to the outer surface of the tube so that, if the tube holding the cigarette is placed upon a horizontal surface such as a bed or carpet, the tube will tilt and bring the unlit end of the cigarette to rest on the horizontal surface. In a second embodiment, a pair of tilt-rings are provided, one ring at each end of the tube, so that the entire tube and cigarette are held above and away form the horizontal surface. The preferred means for limiting the supply of air to the cigarette include tubal perforations of about one-thirty-second of an inch, separated by an average distance of about one-quarter of an inch.

Abstract: A talking book including a power source, switches, voice chips and speaker, all of which are mounted within the book and act together to "read" the words written on pages of the book. The switches are pressure-sensitive types, and marked areas on the pages are pressed in order to activate the switches and the chips in order to produce words or other sounds.

Abstract: Teaching and amusement apparatus includes a self-contained electronic pen which is used in conjunction with specially printed material to provide an interactive system, e.g. in the form of a worksheet or book having question and answer areas. The pen senses differences, not visually discernable, in the infra-red radiation reflectivities of the answer areas to indicate audibly and visually whether a correct or incorrect answer has been selected. The pen operates in a programming mode wherein a program for the particular game to be played is loaded into the apparatus by sensing the reflectivities of areas on the worksheet or book and then is switched automatically into an active mode wherein correct and incorrect answers are sensed. The pen confirms to the user that the program has been correctly loaded into the apparatus.

Abstract: A board game aimed at three to six year olds which is designed to teach and promote good nutrition and exercise habits which result in healthy cardiovascular systems to young children as well as provide entertainment and reinforcement for normative values.
