Abstract: A tamper-indicating plastic closure includes an annular pilfer band which is partially detachably connected to a skirt portion of the closure, whereby the pilfer band remains connected to the closure after closure removal from an associated container. The pilfer band includes at least one fracturable region which fractures during closure removal, whereby the pilfer band splits and separates into a plurality of segments. Each segment is preferably dimensioned to facilitate its removal from an associated container by automatic washing equipment in the event that one of the segments is inserted into the container by a consumer.

Abstract: A container closure having a multiple liner seal is disclosed. The closure comprises a plastic closure cap having a circular top wall portion and a depending annular skirt portion. The skirt portion has an internal thread formation for threadedly engaging a cooperative container. In a typical closure, a pilfer band depends from the skirt portion. The closure cap has an abutment internal thereto, generally at the juncture of the top wall portion and the skirt portion. A first resilient, molded-in plastic seal is positioned in the cap adjacent to and against the top wall portion, and a second resilient plastic seal is positioned in the closure and extends thereacross resting upon the abutment. When the closure is threadedly engaged with a container, the second seal provides a top/side seal to seal the contents from the environs. The closure will seal a container with or without the second seal in place because of the independent sealing capabilities of the first seal.

Abstract: A tamper-indicating plastic closure includes an annular pilfer band which is partially detachably connected to the skirt portion of the closure, whereby the pilfer band remains connected to the closure after closure removal from an associate container. The pilfer band includes a fracturable region which fractures during closure removal, whereby the pilfer band splits and separates. The fracturable region is defined by a pair of circumferentially and vertically spaced, staggered scores which are configured to facilitate high-speed manufacture, and consistent tamper-indication.

Abstract: The present invention is directed to a lug cap or closure that is used in combination with a container for indicating that the container has been opened so as to indicate loss of seal or tampering. The lug cap includes an upper cap portion and a depending tamper or pilfer band, each having a series of circumferentially spaced lugs. The upper cap portion and the pilfer band are joined by a plurality of frangible bridges. The container finish includes combination camming/locking projections for locking the lugs into a locked position and for separating the pilfer band from the upper cap portion by a camming action when the container is opened. The lug cap may also include a secondary tamper indicating means such as a tamper indicating button in the top of the lug cap.

A first director element is spaced above the driven element and has lesser length and width dimensions than the driven element. A second director element is spaced above the first director element and likewise has lesser length and width dimensions than the driven element. A group of eight of the antennas are positioned in a column to form an antenna array which has substantial vertical polarization, a relatively wide horizontal beam width, approximately 60.degree. and a relatively narrow vertical beam width, approximately 8.0.degree.. The antenna array has a center frequency of 885 Mhz and a bandwidth of approximately 230 Mhz.

Abstract: In a system for monitoring trash compactors, each monitoring unit associated with a trash compactor comprises a transducer for sensing hydraulic pressure, for generating an analog signal from the sensed pressure, and for converting the analog signal to a frequency signal, and a microprocessor. The microprocessor compares pressure signal values generated from the frequency signal over timed intervals to a specified value indicative of a compaction. The microprocessor also compares the maximum pressure signal value generated therefrom, under certain conditions, to a threshold value indicative of the trash compactor having a substantially empty compactor and to a threshold value indicative of the trash compactor having a substantially full container.

Abstract: A closure-assembly includes a molded plastic closure cap, and a disc-shaped insert liner positionable adjacent a top wall portion of the closure cap. An annular shoulder of the closure cap cooperates with the insert liner to form a top/side seal with an associated container. The annular shoulder includes at least one annular liner-engaging rib, which cooperates with the insert liner to enhance sealing performance of the closure assembly, retain the liner in position with the closure cap, and facilitate high-speed closure formation.

Abstract: The invention provides an improved method for preparing fired ceramic oxide material. A ceramic oxide powder is dispersed in an aqueous solution containing a dispersant having as an active ingredient a dissolved salt of an anionic polymer formed from maleic acid, maleic acid anhydride, or fumaric acid. The slurry containing the dispersed ceramic oxide powder is spray-dried, compressed while substantially dry, and heated to produce a fired ceramic material. Ceramic materials having relatively higher density and strength can be produced by the method.

The stock is severable to form individual carriers with three longitudinal rows of container-receiving apertures, as defined by band segments, which include cross segments formed with tear-open tabs. The cross segments formed with such tabs are slitted so as to define a series of frangible bridges, which are staggered transversely, and which can be easily torn by a user pulling on such tabs. Also, a distal portion of each tab is connected to another band segment by a frangible web, which is slitted.

Abstract: An iodide-doped, polythienylene coated electrode suitable for a potentiometric iodide ion sensor and a method for its manufacture are disclosed. The electrode is prepared by polymerizing the polythienylene on a working surface thereof.
