Patent CA-2172752-C (CA)
Inventor: WOLLSCHLAGER DIETER
IPC: B29C45/67
Filed: 1996-03-27
Granted: 1999-03-30
Abstract: A method and an apparatus for closing the tool of a plastics-processing machine, especially a blow-molding machine, concerns a two-part tool (1, 2) which is supported by two tool mounting plates (3, 4), at least one run drive (5), at least two closure drives (8), and such that the closure drives (8) each have a hydraulic piston-cylinder system with a cylinder (9), a piston (10), and a cylinder rod (11), and such that an inflow (14) and an outflow (15) for hydraulic oil is situated at the cylinder (9).  Also, the end of the piston rod (11) has an interlock element (12) which interacts with a counter-piece (13),  such that the piston rod (11) does not interlock with the closure piece (13), in order to apply the closure force, until the tool (1, 2) is situated near its closed position. According to the invention, all the closure drives (8) for closing the tool (1, 2) with a high force are actuated by a common control or regulation mechanism; no synchronization devices between the individual closure drives 8 are present.  The entire closure motion of the tool (1, 2) takes place continuously and without interruption of the closure process.  In this way, a more economical mode of operation is achieved by a simpler and more economical design.

Abstract: A wheel  slip  control  system employs  a method of varying the detection and correction parameters it uses based on whether the wheel/axle combinations on a truck of a rail vehicle operate in the coupled or decoupled modes of operation.   The control  system executes programming  code  featuring detection  and correction logic.  The steps of the method include deriving both detection parameters optimized for each mode called coupled and decoupled detection parameters and correction parameters optimized for each mode called coupled and decoupled correction parameters.  Another step involves monitoring the amount of dynamic braking applied to the  wheel/axle  combinations.     Yet  another  step  involves determining whether the amount of dynamic braking lies for a preset time period within a preset zone of operation for the dynamic braking of the wheel/axle combinations on the truck.  The method provides the coupled detection parameters to the detection logic if the amount of dynamic braking lies within the preset zone for the preset time.   Alternately,  it provides the decoupled detection parameters to the detection logic if the amount of dynamic braking fails to lie within the preset zone for the preset time.  The method provides the coupled correction parameters to the correction logic if the amount of dynamic braking lies within the preset zone for the preset time.  Alternately, it provides the decoupled correction parameters to the correction logic only if the amount of dynamic braking fails to lie within the preset zone
