Patent DE-4315076-A1 (DE)
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/23
Filed: 1993-05-06
Abstract: Valve gated injection molding apparatus for coinjecting and/or sequentially injecting two different fluids through a gate (20) into a cavity (22). An elongated valve pin member (64) is received in an elongated valve sleeve member (56) in alignment with the gate (20) and both are reciprocated rotatably as well as axially by separate actuating mechanisms to control the flow of the fluids through the gate. Each actuating mechanism has a piston driven rack member (96,118) to provide rotary motion which is then converted to axial movement of the corresponding valve member (56,64) between the retracted open and forward closed positions. In one embodiment, helical threads (104,126) on the valve members engage fixed teeth extending inwardly from the surrounding nozzle to convert the rotary motion of each valve member to corresponding axial movement. Linear position transducers on the rack members provide for accurate control of the valve members. This accurate control and the reduction in force required by these rotary axial actuating mechanisms minimizes wear resulting from repeated seating of the valve members. <IMAGE>

Title: Method for influencing the speed of sequences in sorting sidings
Inventor: BOCHMANN KLAUS DR
IPC: B61L17/00
Filed: 1993-08-27
Abstract: In high-performance sorting systems, combined conveying systems have been mounted in the sorting sidings, in which conveying systems the functions of clearing and closing up respectively separated conveying systems are transmitted. A method is to be disclosed in which the power requirements of modern sorting systems are performed at low cost and with which method existing simple conveying systems operate with more intensive power and fulfil higher quality requirements. A simple conveying system is used in which the starting position spacing for the truck (2) is dimensioned in the conveying area (F), in particular in the closing-up area (B) so as to be variable as a function of a variable derivative-actioned length (Vv) and distance (Z) from the destination, which is dependent on the state of occupancy of the track, for the target braking, that is to say a new variable starting position spacing (Sv) is derived with each new calculation of the distance (Z) from the target. With target braking, the target speeds are varied, in which case when the distances (Z) from the target are large, small or negative run-up speeds are prescribed. The method can be applied in particular for sorting sidings of level sorting yards with high-performance operation, in which yards conveying systems operate. <IMAGE>
