Abstract: An automatic control for terminating the filling of a sausage casing on a sausage casing machine (10) has a sensor (34) on the machine (10) to detect when the rearward end of a telescopic casing is closely adjacent the discharge end of a meat stuffing tube. The sensor (34) is connected to the meat emulsion pump (14) for stopping the pump (14) under such conditions. A timer (30) or pulse counter is associated with the computer (36) on the machine (10) to "measure" when the rearward end of the casing substantially reaches the discharge end of the stuffing tube (16). The timer (30) or counter is operatively connected to the power system (not shown) for rendering the machine inoperative after a predetermined amount of time or pulses. The sensors (34) and timer (30) are connected to the above stated respective components through a computer (36) so that the computer (36) can automatically compensate for the operative time of the second cycle to accommodate for speed changes imposed on the power system in the second cycle. The method involves locating the sensor (34) at the above designated positions to permit the sensor (34) to shut down the pump (14) and to trigger the timer (30) to subsquently shut down the machine automatically.

Title: Micro-porous filter
Inventor: KENYON LEWIS W
IPC: F21S9/02
Filed: 2001-10-24
Granted: 2009-09-01
Abstract: A micro porous gas breather/filter assembly can be coupled to a housing of an electrical enclosure. The filter assembly has a two portion housing with the filter disposed between them. An adhesive on the filter attaches the filter to one or both portions of the housing. The filter allows gas to pass from the enclosure through the filter and to the atmosphere, but prohibits liquid from passing into the enclosure device. By filtering gases and liquids in this manner, the filter vents explosive and/or flammable gases from an electrical enclosure, while preventing liquid and other contaminants from entering the enclosure and damaging the electrical device or its wiring.
