Filed: 1996-03-11
Abstract: A combination of a preprinted pressure sensitive label and an electronic article security system target is provided, preferably as a supply of labels on a backing material web with the target between. The labels preferably extend about at least about 1/8th inch around the edge of the target to directly adhere to the products. Articles may be selectively marked with targets so concealed to deter theft with fewer targets. The combinations may be formed by applying first the target, then the label, to the article. Preferably, label and target combinations are supplied on a web and are then applied to the products. Combination label and target supplies may be formed by separating the preprinted labels from their backing material webs, applying the targets to either the label or the backing material, and then combining the label with either the same backing material web or a different one. With discrete cut labels on a backing web, pressure sensitive adhesive coated targets are applied to the web and pressure sensitive labels are applied over them. For high speed production, targets are applied to the adhesive side of an uncut label web that has been separated from its backing material, then relaminating the combination onto the same or a different backing material web. Discharges of electrostatic charge that could damage the target circuits are reduced by using rollers and peeling knives made of non-electrically conductive materials to contact the markers or targets and by using ionized gas to neutralize the charge.

Filed: 1996-03-20
Abstract: A plurality of spaced ceiling mounted fixtures or other controllable electrical appliances have radiation detectors mounted within each fixture and wired internally of the fixture to a dimming circuit or to a ballast.  The radiation detectors have sensitivity over a wide angle and have elongated plastic radiation conduction rods which extend to or beyond the plane of the lens of the fixture to be located free of shadow effects of reflections of the fixture lens.  A flexible end light fiber optics can be used in place of the acrylic rods.  A narrow beam radiation transmitter selectively illuminates one of the rods or end light fiber optics without illuminating the others.  The dimming circuits or ballasts within the fixtures can be further controlled by external dimmers, occupancy sensors, timeclocks, photosensors and other types of input devices.  The radiation detector and ballast can occupy a common housing and share the same power supply and circuit board.  The microcontroller for the radiation detector operates with a 4 of 4 voting mode until a valid signal is detected to switch the system to a 3 of 4 voting mode.  A novel mounting adaptor for mounting a visible light fiber optic cable is disclosed with the visible light fiber optic cable conducting infrared radiation for up to 24 inches.

Title: Pretreatment of chips before cooking
Inventor: HENRICSON KAJ O
IPC: D21C1/06
Filed: 1996-04-24
Abstract: The strength properties of chemical cellulose pulp (particularly kraft pulp) are improved by substituting a cold impregnation soak for conventional impregnation procedures. After steaming, wood chips are soaked in an alkaline liquid at a temperature of about 80-110°C (preferably 80-100°C, or 90-105°C) for between one-half-72 hours (typically about 2-4 hours) at a pressure of about 0-15 bar (preferably about 1-5 bar), to dissolve at least about 8% of the wood (preferably about 10-20%) and at least about 15% of the lignin. The alkaline liquid used preferably contains sulfide (e.g. black liquor, green liquor, white liquor, or mixtures thereof), but almost any alkaline liquid having an alkali concentration of about 1.0 mole of NaOH/liter or less (typically about 0.75 m/l or less) is suitable. The wood chips are then raised to a cooking temperature of about 145-180°C and cooked to produce the cellulose chemical pulp. There may be an intermediate step, between soaking and raising the cooking temperature, of heating the wood chips to a temperature of about 110-150°C (preferably about 120-140°C) for about 10-90 minutes (preferably about 10-30 minutes). Alternatively or additionally the majority of the dissolved lignin (and/or other solids) may be removed before raising the wood chips to cooking temperature. The system for treating the wood chips need only include a low pressure soaking vessel (with an associated pump or other transfer device) in addition to conventional equipment.

Title: Excess speed calculator and signaler
Inventor: MCKENNA PAMELA MARY
IPC: G01P3/50
Filed: 1996-09-30
Abstract: In a device for calculating and signaling excess vehicular speed to the vehicle occupants, it is known to have a component which transmits a digital signal of the lawful maximum roadway speed limit posted from a fixed point transmitter to an in-vehicle signal receiving component which in turn sends the posted maximum speed digital value to the Excess Speed Calculator and Signaler. An additional component is a digital speedometer which sends the actual vehicle speed digital value to the Excess Speed Calculator and Signaler. The Excess Speed Calculator and Signaler device, upon receiving these two digital values, makes a comparison of the maximum posted speed limit value to the actual vehicle speed value and subsequently sends a signal to an audible alarm and visual display inside the vehicle when the posted digital roadway speed limit is exceeded by the actual digital speed of the vehicle. The visual display and audible alarm will continue until: the driver reduces the vehicle speed to the lawful maximum posted roadway speed limit, or the driver turns off the Excess Speed Calculator and Signaler device, or the vehicle proceeds along the roadway until the Excess Speed Calculator and Signaler device receives another digital signal from the next fixed point posted roadway maximum speed transmitter, recalculates for excess vehicular speed and stops sending the visual and audible signals when vehicular speed is within the lawful posted roadway speed limit or alternatively, signals the newly calculated excess speed condition. There is no previous application known which calculates a comparison of the lawful maximum roadway speed limit posted to the actual vehicle speed for the purpose of issuing an alarm to the occupants inside the said vehicle when the speed of travel is in excess of the lawful maximum roadway speed limit posted.
