Abstract: A processed meat product such as bacon and a process for treating meat cuts for use in the production of a processed meat product. Particulate meat material is mixed with a pickle solution to form a mixture. The pickle solution and meat material mixture is fed through a reduction mill to form a suspension. The temperature of the suspension is raised during milling to approximately 45°F or higher. Subsequent to milling the temperature of the suspension is decreased to approximately 32°F or lower. The cooled suspension is then injected into a meat cut. The injected meat cut is then thermally treated to form a bacon or bacon-like product having an increase in weight of 0% to 49% above the weight of the meat cut prior to injection.

Abstract: A noise reduction structure for an aluminum-based driveshaft tube includes a generally cylindrical member having a predetermined length. The noise reduction structure is disposed within a driveshaft tube in a press fit relationship with the inner surface of the tube. In general, the noise reduction structure is positioned within the driveshaft tube at a location where the amplitude of a standing wave caused by the reflection of the sound waves back and forth along the driveshaft tube is at its maximum value. The length of the noise reduction structure may be about 10% or less of the value of the length of the driveshaft tube. In a first embodiment, the noise reduction structure is formed from a polymeric foam material having a density of less than about 10 lb/ft3. Preferably, the material has a density in the range of about 2 lb/ft3 to 10 lb/ft3, and more preferably, in the range of about 3 lb/ft3 to 7 lb/ft3. One type of material which is particularly well suited for this invention is a polymeric cushioning foam having a density of about 5 lb/ft3. In a second embodiment, the noise reduction structure is foamed from a plurality of relative long cylindrical members that are press fit within the driveshaft tube and are located equidistantly from one another. Each of these cylindrical members is preferably foamed from a polyether material having density of at least 1.4 lb/ft3, and most desirably are formed having a density of 1.5 lb/ft3. In a third embodiment, the noise reduction structure is formed from a single elongated cylindrical member that is press fit within the driveshaft tube and is preferably formed from a polyether material having density of at least 1.4 lb/ft3, and more desirably is formed having a density of 1.5 lb/ft3. One or both of the end portions of the driveshaft tube may be formed having a reduced diameter.

Abstract: Cette invention concerne un procédé et un système de moulage par injection d'articles en plastique faisant appel à une cavité de coulage (325) à volume variable. Dans un mode de réalisation, le volume varie durant l'introduction de gaz comprimé dans un conduit de la cavité du moule relié à la cavité de coulage. Dans un autre mode de réalisation, le volume de la cavité de coulage varie durant l'injection du plastique remplissant la cavité du moule. Un piston (329), pouvant effectuer un mouvement de va-et-vient, est monté dans un cylindre (327) et définit le volume variable de la cavité de coulage. Dans un mode de réalisation, un circuit de commande pneumatique (166) permet de réguler la pression à la surface inférieure du piston afin de commander la position de ce dernier à l'intérieur du cylindre et, donc, le volume de la cavité de coulage. Dans un autre mode de réalisation, un ressort pneumatique (188) permet de réguler la pression sur le piston, laquelle permet de contrer celle exercée par le plastique sur ce même piston. Dans un mode de réalisation, une goupille d'arrêt (144) connectée au piston empêche celui-ci de sortir du cylindre lorsque le moule est ouvert et que le plastique solidifié est éjecté de la cavité de coulage. Une goupille d'éjection (186"") permet d'éjecter le plastique après son retrait de la cavité de coulage. Cette invention concerne également différents procédés d'introduction d'un volume déterminé de gaz sous pression à la surface inférieure du piston, y compris à travers la goupille d'arrêt.

Abstract: The present invention relates to a peripheral microcontroller for providing a high performance USB (Universal Serial Bus) connection to existing peripheral architectures (such as printers and disk drives with existing microcontrollers) and to new peripheral architectures (such as a 4-port USB-to-Ethernet Bridge). The USB peripheral microcontroller includes three units. A Serial Interface Engine (SIE) connects to a USB host or USB hub. A      Microcontroller (MCU) Interface Unit connects to one or more peripheral devices such as ISA-like peripherals. A Memory Management Unit (MMU) provides a buffering mechanism between the SIE and MCU Interface Unit. The MMU utilizes a unique data packet buffering architecture. Packets received at the MMU from a peripheral for transmission to the USB host and packets received at the MMU from the USB host for transmission to a peripheral are buffered in a RAM. The capacity of the RAM is dynamically allocatable among various USB endpoints and the USB host so that the size of the RAM is minimized. The data path of the inventive USB peripheral controller is also highly advantageous. The SIE accesses the packet buffer RAM via a DMA controller in the MMU. The MCU Interface Unit accesses the packet buffer RAM via a microcontroller or a DMA controller. An arbiter in the MMU enables these multiple masters to access the packet buffer RAM.

The intelligent network centre transmits preferably by using transmits a telecommunications network signalling the target number, caller's number and address of the company's to a voice server (22), which is a computer capable also to identify telephone numbers and formulate voice messages. The voice server converts the target number into data and transmits the data and the caller's number to the company's data system using a data network, _preferably a data network based on TCP/IP protocol. The company's data system stores the data in the data system and formulates a return message, which includes an acknowldedgement of the received data and further a possible additional information, and transmits it to the voice server using the data network. The voice server transmits using the mobile communications network the return message either as a GSM short message (text message) or as a voice message to the mobile station, which transmitted the data code, or as a pager message to the desired pager device.
