摘要:
A knife wheel assembly suitable for forming a butt splice to join together a web from a new roll of material to a web which is from an expiring roll of material and which is being run, downstream from the expiring roll, under tension along a predetermined path of travel that includes a running web storage means and a press or other web handling means. To form the butt splice, the leading end of the new web is trimmed by moving one knife wheel assembly along the cutting edge of an anvil. The trimmed leading end is held against the anvil, and a piece of tape is applied to the leading end so that a portion of the tape projects downstream from that end. The portion of the expiring web, adjacent to the anvil, is then momentarily stopped, held against the anvil, and trimmed by another knife wheel assembly, along the same cutting edge of the anvil, by movement of the knife wheel assembly across the web, from side-to-side, along the cutting edge of the anvil. As the trailing end of the expiring roll is trimmed, the knife wheel assembly also simultaneously adheres the trailing end to the downstream portion of the tape. This serves to join this trailing end of the expiring roll and the leading end of the new roll together. Only the portion of the web of the expiring roll adjacent to the anvil is momentarily stopped while the expiring web is trimmed and adhered to the leading end of the new roll.

The disclosed butt splicing apparatus and method is adapted to be used with rolls of material supported on turret-type roll unwind stands. A splicer embodying the invention includes a nip assembly, a new web preparation assembly, a new web and tape holding assembly, and a web cutting and adhering assembly. The nip assembly serves to clamp the expiring web during a splicing operation. The new web preparation assembly serves to prepare the leading end of the new web for the splicing operation. The new web and tape holding assembly serves to hold a portion of the new web, immediately upstream of its leading end, and to hold a strip of adhesive tape in preparation for the splicing operation and during the splicing operation itself. The web cutting and adhering assembly serves to cut the expiring web during the splicing operation and to cause the cut part of the trailing end of the web and the leading end of the web to adhere to the adhesive tape simultaneously as the cutting of the expiring web occurs.

An aqueous concentrated fabric softening composition comprises an aqueous base, more than 10% of a water-soluble cationic softener and at least 3% of an alkoxylated amine having less than 7 alkylene oxide groups per molecule such as ethoxylated tallow amine. The total level of cationic and nonionic components is preferably less than 25%. The alkoxylated amine improves processing by lowering the initial viscosity of the product.

A lubricant additive gel formed by the gellation of two or more lubricant additives for the slow release of the additive components into a fluid. The lubricant additive gel slowly releases into its component lubricant additives when contacted with the fluid such as an oil thereby serving as a lubricant fluid such as an oil thereby.

A system and method for controlling game play at a pay-for-play entertainment system. The entertainment system may include an entertainment unit, a remote activation unit, and at least one game play light source. The remote activation unit may be configured to have the game play light source be in an on condition during purchased game play and in an off condition when purchased game play time or credits have expired. The present invention may also include a game play detection apparatus that may detect game play activity. The detection of game play may be communicated to the remote activation unit to determine if the detected game play activity is associated with purchased game play. If the detected game play activity is unauthorized, i.e. the game play has not been purchased, the remote activation unit may communicate an “on” signal to an auxiliary light and/or speaker.

A method for play of a parlor entertainment unit including a remote activation assembly and an activation-sensing unit. The activation-sensing unit, which may be battery operated and housed in the entertainment unit, may be in an energy-conserving sleep mode until the activation-sensing unit receives a wake-up signal. In one embodiment, the wake-up signal may be generated by the engagement of an activation mechanism, such as a coin slide. After being awoken, the activation-sensing unit may transmit an inquiry to the remote activation assembly as to whether the associated entertainment unit has been selected for play and/or whether there is a sufficient number of credits available for play. If that entertainment unit has not been selected for play, the activation-sensing unit may return to a sleep mode. However, if sufficient play credits are available for the entertainment unit, play may commence.

Aluminum or aluminum alloy on each of a pair of semiconductor wafers is thermocompression bonded. Aluminum-based seal rings or electrical interconnects between layers may be thus formed. On a MEMS device, the aluminum-based seal ring surrounds an area occupied by a movably attached microelectromechanical structure. According to a manufacturing method, wafers have an aluminum or aluminum alloy deposited thereon are etched to form an array of aluminum-based rings. The wafers are placed so as to bring the arrays of aluminum-based rings into alignment. Heat and compression bonds the rings. The wafers are singulated to separate out the individual semiconductor devices each with a bonded aluminum-based ring.
