Abstract: A reel hub (5), an inside rod (70) of which can slide axially when acted upon by a seizing rod (82), forms part of the transfer apparatus (3). By bringing the transfer apparatus opposite the hub of a rotating reel (21, 20), and by withdrawing the inside rod from the hub, the hub is disengaged from a machine (1), the reel continuing to rotate with its hub fixed to the transfer apparatus. This apparatus can then be moved in directions situated in the plane of rotation of the reel and brought opposite another shaft of the machine in order to reattach the hub there by reversing the foregoing procedure. A rotating reel, especially one paying out a strip of cigarette paper, can thus be moved without subjecting the strip of paper to any torsion. Other operations relating to the automatic operation of the machine are also possible with the aid of the transfer apparatus.

Abstract: An article is provided in which a tobacco flavor medium is electrically heated to evolve inhalable tobacco flavors or other components in vapor or aerosol form. The article has a plurality of charges of the tobacco flavor medium which are heated sequentially to provide individual puffs.

Abstract: A programmable logic device is presented comprising a global interconnect array whose lines are fed via programmable multiplexers to logic array blocks. The global interconnect array lines are fed to the multiplexers in a specific pattern which maximizes the user's ability to route a selected line to the output of a selected multiplexer, while at the same time maintaining higher speed and lower power consumption, and using less chip array than prior art programmable logic devices using programmable interconnect arrays based on erasable programmable read-only memories.

Abstract: Gripper apparatus for electric motor components that can be used to grip components of different sizes, and that can rotationally index electric motor components of different sizes, is provided. The gripper apparatus has two oppositely facing gripper arms with complementary V-shaped faces sized to accommodate a range of sizes of components. The arms are moved together in unison to center and grip the component. After the component has been gripped, an indexing pawl rotates the component. A tooth is urged against the component and stops the rotation when it enters a depression or slot in the component, indicating that the desired angular position has been reached.

Abstract: Film originating NTSC video signals are converted to the PAL standard by a process which detects and eliminates duplicate fields. Video frames corresponding one-for-one with the original film frames are line interpolated to provide a PAL signal with minimal artefacts. Edits are detected and steps taken to avoid interpolations across a cut.

Abstract: An article is provided in which a replaceable tobacco flavor medium is electrically heated by a set of permanent reusable heaters to evolve inhalable flavors or other components in vapor or aerosol form. Each heater heats only a portion of the available tobacco flavor medium so that a plurality of individual puffs of tobacco flavor substance can be delivered sequentially to the smoker. The tobacco flavor medium preferably contains tobacco materials.

Abstract: Apparatus and a method for laminating patches to a base web accurately, and as efficiently as possible, are provided. Two webs are fed at speeds which are related as the ratio of the width of each patch to the separation distance between patches, the patch web moving more slowly. Patches are cut from the patch web and transferred to the other web while being accelerated to the higher speed.

Abstract: A method and apparatus for cutting a longitudinally advancing a rod of tobacco-containing material into lengths including a cut-off wheel having two or more blades equally spaced around the wheel periphery, a sharpening stone driven independently by a motor at a fixed location to sharpen one side of each blade as the wheel rotates, and a deburring stone oscillating in a path between two points at a frequency such that the stone intersects the path of travel of each blade for deburring the other side of each blade. The deburring stone may be located on the ledger device of a cigarette manufacturing machine where the ledger is oscillating at a frequency that is a multiple of the number of blades of the cutoff wheel for each revolution of the wheel.

Abstract: A heating element to provide heat to a tobacco flavor medium, for use in an electrical smoking article, by converting electrical energy to heat through the use of a material with electrically resistive properties is provided. The material is arranged in a radial array of blades with a current density profile such that a maximum area of each blade provides heat to the tobacco flavor medium dispersed thereon. The blade is generally U-shaped to assure dispersion of heat evenly to avoid hot spots along the blade and is tapered to reduce mass toward the mouth end of the heating element so as to maximize the heated area.

Abstract: A method of forming a gummed band on a web of paper (1) is provided. A marginal band (7) forming a seam is projected by one (10) of two devices (10, 11) under the action of compressed-air pressure, the air being pre-heated (20) and passing into a feed line (19), whereas an inside gummed band (6) is formed by the other device (11) fed with cold compressed air through a duct (21). An adhesive is contained in a reservoir (8), kept under pressure by means of a tube (12), and reaches the projection device through another duct (9).

Abstract: Cigarettes are restrained by arresting a cigarette oriented askew relative to the other cigarettes flowing into a hopper before that cigarette blocks the distribution channels of the hopper, thus stopping the manufacturing process. An arrested cigarette is furthermore detected. The hopper equipped with the restraining device, particularly a hopper for distributing cigarettes, contains a set of gratings (2) halfway up it, made up of a fixed grating (20) above which there is a movable grating (21) actuated with a translatory reciprocating movement. The set of gratings can restrain any cigarette (13A) presented and traveling crosswise in the hopper before this cigarette can go on to interrupt the flow through distribution channels (15) at the outlet of the hopper. A detection device (3) comprising in particular a photoelectric cell (31) and a light source (30) detects a space (13B) void of cigarettes, caused by the crooked cigarette restrained by the set of gratings, and transmits an alarm.

Abstract: A roll (30) of adhesive worked between two rollers (10, 12) of the gumming device is supplied by feed nozzles (34a, 34b) projecting fine streams of adhesive (35a, 35b) with monitored flow. In case of an increase in the measured viscosity of the adhesive or stopping of the machine on which the gumming device is used, a water-atomizing device (40) allows the viscosity to be reduced and prevents the adhesive from drying out. A dimension of the adhesive roll is monitored and controls regulation of the output of the adhesive-feeding nozzles. The gumming device thereby ensures proper gumming of a strip of paper (2).

Abstract: A method and apparatus for erasing Flash EPROM cells that avoids overerasure is provided. A high-impedance device is placed between the drain of the cell and the high-voltage supply used to erase the cell. As soon as the cell enters the onset of depletion and begins to conduct, most of the high voltage is dropped across the high-impedance device, leaving insufficient potential across the cell for Fowler-Nordheim tunneling to continue. The erase process is thus self-limiting. The process can be used on a chain or array of EPROM cells, with erasure stopping when any one of the cells conducts. Bias differences between erase and read modes assure that the cell that first goes into depletion is not in depletion in normal operation.

Abstract: A macrocell with product term allocation and adjacent product term stealing is disclosed. Programmable configuration switches provide product term allocation by directing input product terms to an OR gate or to the secondary inputs to a register. Adjacent product term stealing is accomplished by providing the output of the OR gate of each macrocell as an input to the OR gate of an adjacent macrocell. By using the output of the OR gate of the first macrocell, the adjacent macrocell steals the product terms and the OR gate of the first macrocell for use in its own OR gate. An arbitrarily wide OR function can be implemented by daisy chaining the OR gates of adjacent macrocells. Because programmable configuration switches can direct individual input product terms to the register logic instead of the OR gate, the register logic can be used even when an adjacent macrocell steals the OR gate.

Abstract: Apparatus for reclaiming tobacco from rejected cigarettes is provided. A receiving drum having holes to receive the rejected cigarettes is provided coaxial with a fluted drum, so that both drums rotate in the same direction. Via a control ring turning in synchronization with the receiving drum, jets of compressed air eject the tobacco from the rejected cigarettes, before the empty cigarette wrapper (tube) is also expelled from the receiving hole. A timing disk controls the work cycle. Suction pressure applied to the receiving holes of the receiving drum sucks the rejected cigarette into a predetermined stop position in the receiving hole prior to the application of compressed air. With the aid of restraining needles, the cigarettes are held firmly while the jet of compressed air is applied to expel the tobacco. On release by the restraining needles, the cigarette wrapper (tube) is ejected from the receiving hole to a discharge chute by a jet of compressed air applied via the control ring.

Abstract: A vacuum cleaner headlight system incorporating a light pipe is provided. The light pipe includes reflex optics to control the distribution of light across the width of the output edge of the light pipe, as well as to prevent light from escaping through the sides of the light pipe. A reflex optical reflector is also part of the system, for reflecting light from a light bulb into the light pipe without requiring a metallized mirror.

Abstract: A multiple unit carton composed of a plurality of individual cartons joined by carrier means. Each carton holds at least one pair of cigarette packs aligned with their long walls abutting, and their short walls coplanar. The multiple unit carton is preferably dimensioned to resemble a ten-pack cigarette carton so that the multiple unit carton may be passed through commercially available tax-stamping machinery, which is commonly designed to process ten-pack cigarette cartons. The individual cartons are joined with adhesive bearing carrier means such that the cartons remain securely connected when being passed through tax-stamping machinery.

Abstract: A dual cigarette carton formed from two substantially identical single cigarette cartons. A label bearing indicia encoded for the automatic pricing of the dual carton is placed across adjacent coplanar walls of the two single cartons. The indicia are positioned such that they are rendered unreadable by automatic equipment when the two single cartons are separated for individual sale. Each single carton further includes indicia encoded for the automatic pricing of a single carton, the indicia being positioned such that they are not readily visible when the single cartons are connected to form a dual carton.
