Abstract: An apparatus for the opening of paper bobbins and other rolls of material is provided. A flat blade is advanced from the side of a wound roll of material such that it intersects the roll over substantially its entire width. A cutting blade or other cutting mechanism then severs the layers of the roll which are outside the flat blade, and the flat blade protects the inside layers from being damaged. In preferred embodiments, a jet of air or other gas may be used to ease the insertion of the flat blade, or a gripping device which pinches the surface of the roll between opposed friction pads creates an arch in the surface of the roll through which the blade is inserted. The device is particularly suitable for use in cigarette making machines which require undamaged paper feeds.

Abstract: A device for preparing and opening a roll of a strip of supple material. A flat blade is provided and is inserted from one side of the roll to separate the top layer, which is to be cut, from the lower layers. When the top layer is cut, the cutting portion of the cutting blade comes to rest against the flat. A clamp holds the cut layer and a transferring device handle the cut top layer.

Abstract: This disclosure relates to a method and apparatus for reliably inserting a tab or other marker into a bobbin of material which is undergoing a converting or other processing step. A spindle having a retention device such as a vacuum or magnetic zone which holds the tab or marker with an adhesive side facing outwardly is described. In operation, the spindle is moved into engagement with the surface of the web and the tab or marker is applied precisely and with considerable force. Reduction in unplaced tabs, paper jams, and tearing may be accomplished by the reduction of user error.

Abstract: A novel controller in an electrical smoking system and method, wherein the method includes the steps of: establishing a preferred thermal pathway to be executed with each heater activation responsively to a puff on an electrically heated cigarette; configuring a power cycle in accordance with the desired thermal pathway; dividing the power cycle into at least first and second phases each having a respective, predetermined time period and total energy input for each phase; and adjusting a respective duty cycle (or other power-adjusting factor) in each phase of the power cycle responsively to a voltage reading of the power source such that the established, respective total energy input of each phase is achieved during the time period of each power cycle.

Abstract: A novel cigarette adapted for use in an electrical cigarette system comprising a tobacco rod having filled and unfilled tobacco rod portions and being arranged so that electrical heater elements may overlap the filled and unfilled tobacco rod portions. The tobacco rod includes a tobacco web rolled into tubular form. The tobacco web is constructed in accordance with a novel process comprising the steps of converting tobacco feedstock into a continuous sheet of tobacco web and converting the continuous sheet of tobacco web into one or more bobbins of tobacco web suitable for automated manufacture of cigarettes.

Abstract: A method and apparatus for detecting, locating, isolating and controlling variations in the manufacturing process by transient thermography. A heat source imparts heat to a surface which is radiated in the infrared region. Infrared sensors are coupled to a processor which tracks the physical characteristics of the sample, and provides feedback to a central process controller to make adjustments to the manufacturing process.

Abstract: An apparatus for forming a tobacco rod for cigarette manufacture, fitted with a suction-type rod conveyor equipped with a revolving, continuous, porous belt, to which vacuum is applied from the top and on whose underside tobacco shreds are conveyed along a tobacco channel. The apparatus has a pre-equalizer for purposes of equalizing the height of the tobacco rod being conveyed by removing a part of the tobacco rod. The apparatus further has a device that serves to compact the tobacco rod at regular intervals and further has an equalizer that equalizes the height of the tobacco rod after it that is compacted at regular intervals by removing additional tobacco from the tobacco rod. The pre-equalizer has a revolving blade which is positioned directly below the tobacco channel.

Abstract: A thermoplastic film bag pack where each bag has a bottom, front, rear, and gusseted side walls, an inside and outside surface and a cut-edge mouth portion. The mouth portion has double film loop handles as integral extensions of the walls at its opposite ends. The external surface of the bag at the cut-edge region of the mouth between handles has been subjected to a corona discharge treatment to such an extent that adjacently facing cut-edge regions will be releasably adherent until a moderate force separates them. This condition provides for effective dispensing of grocery bags. A method of forming the bags and a system for dispensing is also disclosed.

Abstract: The invention relates to a mold apparatus and a process for forming a lid latching mechanism in a thermoplastic container. The lid latching mechanism features a large, trapezoidally-shaped opening hole. The trapezoidal shape has been found to reduce the amount of tearing that can occur along the edges of an opening formed during the thermoforming process. The opening is created by the engagement between a fixed shear key mounted in a first mold member and a movable shear key which has a trapezoidally-shaped cutting surface and is mounted in a second mold member. The movable key travels along an inclined path as the mold members close on a preheated thermoplastic sheet to form a container.

A process for the thermal densification of thermoplastic articles are also provided.

Abstract: A method and operating technique for treating diene-containing aliphatic streams by introducing the light hydrocarbon stream at a top portion of a vertical stripping tower having an upper catalytic contact zone containing a bed of solid hydrogenation catalyst particles and a lower contact zone, and introducing a light gas stream containing hydrogen at a lower portion of said stripping tower. Selective hydrogenation is effected by flowing the light hydrocarbon stream and light gas stream countercurrently in contact with the solid hydrogenation catalyst particles under hydrogenation and stripping conditions, thereby converting said diene to mono-alkene in the upper contact zone.
