Abstract: A barrier system for use with a trafficable surface that penetrates a boundary to control access by vehicles and to permit uncontrolled access by pedestrians. The system includes a turntable providing a surface that is rotatable generally in the plane of the trafficable surface. Impact elements are arranged along the surface in a pattern having a spacing configured to permit passage by pedestrians and to prevent passage of vehicles when the turntable is in a first position and to permit passage of vehicles when the turntable is rotated to a second position. The system controls vehicle traffic across the boundary by moving the turntable between the first position and the second position.

Abstract: An article, such as a filter or film, has a treated laminate with an expanded PTFE membrane and a porous support scrim. The treated laminate is formed by contacting a laminate having an expanded PTFE membrane and a porous support scrim with an oleophobic treatment agent dissolved in an organic solvent. The oleophobic treatment agent is deposited onto the expanded PTFE membrane and porous support scrim as the organic solvent is removed. The oleophobic treatment agent is typically a fluoropolymer. The article can be used, for example, as a filter over a port in a housing of an electronics or other device.

Abstract: This invention refers to a paper having crossdirectional regions having increased basis weight. The paper of this invention is especially useful as a wrapping material for a smoking article. The paper may be produced by depositing additional material onto a moving base web in a papermaking machine. The additional material is deposited by means of a rotating drum containing a plurality of slits through which the additional material passes.

Abstract: The sidestream smoke associated with a cigarette or cigarette-like smoking article is reduced by wrapping the tobacco in a paper wrapper having an additive, such as an organic acid, an acidic or neutral salt or an organic acid in combination with an acidic salt or neutral salt added thereto.

Abstract: This invention relates to the control of the burn rate of a cigarette. The burn rate is controlled by the use of a paper wrapper to which regions of cellulosic material is applied and bonded. The cellulosic material is applied during a manufacturing step for the base paper wrapper, either off or on-line of the paper wrapper-forming machine.

Abstract: A paper wrapper for a cigarette is prepared using fine particle size calcium carbonate as the mineral filler for the purpose of burn rate, puff count and tar delivery control.

Abstract: The sidestream smoke associated with a cigarette or cigarette-like smoking article is reduced by wrapping the tobacco in a paper wrapper having a burn modifier, such as an acidic salt, added thereto. Preferably the paper wrapper has a high basis weight and low porosity.

Abstract: The sidestream smoke associated with a cigarette or cigarette-like smoking article is reduced by wrapping the tobacco in a single sheet of paper having multiple layers.

Abstract: In a film wrapping machine for wrapping packages in stretchable film, a monitoring system is provided to generate a signal each time film is drawn into the machine. If no film is drawn into the machine indicating that the film source has expired, broken or otherwise become disengaged from the film feeding apparatus for the wrapping machine, the machine is stopped. The film draw into the machine is monitored by an electrical switch which is coupled to a tensioning roller, the motion of which is adjusted to activate the switch each time even at least a minimum length of film is drawn into the machine.

Abstract: A computing weighing scale is disclosed wherein a single multi-digit numerical indicator is driven in real time by the scale microcomputer to display, sequentially, weight of the article, price per unit weight, and total price or value of the article. The indicators are part of a display which also includes function words identifying the nature of the information to the scale operator and customer. The scale also includes weight code generating mechanism, a keyboard for entering numerical information, and the micro-computer.The single multi-digit indicator can also display tare weight, which is entered via the keyboard when there is no weight on the platter. If tare is entered and subsequent weight on the platter is less than entered tare, the calculating function is inhibited. If platter motion is detected with weight on the platter, the display will reset to the weight indicating condition and then sequence to show again price per unit weight (if entered) and total price.

Abstract: An apparatus allowing the ticket printer of a computing scale to be used for printing normal weight, value and price per unit weight labels or alternately for printing labels indicating a manually entered selling price. The selling price label can be used in sale by unit or sale by count merchandise pricing. Dual use of the normal scale printer for preparing either type of label reduces the equipment needed at a pricing station in addition to lowering the investment required for machine printed merchandise pricing. Automatic changeover from the weighed value to the sale by unit mode of operation in response to scale weight indication is also disclosed.
