Title: Method and arrangement for neural modeling of a paper winding device
Inventor: LIEPOLD HELMUT
IPC: B65H18/26
Filed: 1998-11-03
Abstract: The invention relates to a method for modelling a paper winding device, especially a drum cutting and winding machine. Control variables and influencing variables (70, 80) are determined and stored as a function of time. Said variables are used to determine the strength of the strip (FAW(r)), according to the number of wound layers, or a correlative variable is used and considered as a target variable along with the other relevant control and influenced variables to enable a neuronal network to be trained as a model for a nip (Ni) for said winding device. New data for training the network can be continually obtained during operation of the installation, thereby improving the model. Optimum control parameters can be determined to meet various production requirements by means of an iterative process dependent upon the winding quality (100) which can also be determined from the strength of the strip.

Title: Rotary articulated pusher for removing items, such as luggage, from a conveyor belt
Inventor: LEE PHILLIP L
IPC: B65G47/82
Filed: 2001-04-19
Abstract: For use with an elongate conveyor belt designed to transport articles from one location to another, a novel pusher device mounted adjacent one long side of the belt. The pusher device utilizes an elongate, rotatably mounted arm having first and second ends, with the first end being pivotally affixed at a location relatively close to the belt, and arranged to rotate about the fixed pivot for less than 90°. The arm normally resides in an inactive position extending along the long side of the belt, with the second end of the arm being arranged to move outwardly, on occasion, from the inactive position and across at least a portion of the belt when an article is to be deflected off of the belt. An article-engaging paddle is pivotally mounted on the second end of the arm, and a novel actuating device causes selected rotation of the arm about the fixed pivot, such that upon the actuating means being activated to cause the arm to undertake rotation about the fixed pivot, the paddle will move in an outward stroke to briefly contact the selected article and to cause such article to be deflected off of the belt. The actuating device thereafter causes the arm to undertake a rapid return stroke and to resume its inactive position.

Title: Compaction roller
Inventor: MIJBURGH CHRISTOFFEL AVRIL
IPC: E02D3/02
Filed: 1999-11-08
Abstract: The invention concerns a soil compaction roller (10) and a soil compaction machine of which the roller (10) forms part. The roller (10) comprises a multi-sided, out-of-round, peripheral compacting surface (16) which can roll over a soil surface which is to be compacted. The compacting surface (16) is defined by a series of angularly spaced salient points (20) and a corresponding series of compacting faces (22). Each compacting face (22) is outwardly convex in shape and extends continuously between two adjacent salient points (20). When the roller (10) is operative with the compacting surface (16) rolling over the soil surface, the roller rises up on each salient point (20) in turn, storing potential energy, and thereafter rolls downwardly onto the succeeding compacting face (22) to transmit the stored potential energy to the soil surface to compact it. The instantaneous centre of rotation of the compacting surface (16), where it contacts the soil surface during rolling, moves continuously about substantially the full extent of the compacting surface.

Title: Freeze point protection for water cooled chillers
Inventor: MCQUADE WILLIAM
IPC: B67D1/08
Filed: 2000-01-13
Abstract: A freeze point protection method and system is provided for water cooled chillers. The method prevents freezing of chilled water and damage to the chiller. The method allows the evaporator temperature to drop below a freezing temperature for a predetermined amount of time prior to shutting down the chiller (126). The temperature of the refrigerant in the water chiller (126) is periodically sensed. The amount of time that the chiller (126) is below a predetermined freezing temperature is periodically counted and compared with a determined maximum time that the chiller (126) may operate at a sensed temperature below the predetermined freezing temperature without damaging the chiller (126). The method will shut down the water chiller (126) if the counted time exceeds the determined maximum time. A system for shutting down a water cooled chiller (126) to prevent freezing of chilled water is also provided.
