Patent DE-19544592-A1 (DE)
Inventor: CORDS CARL
IPC: F15B13/042
Filed: 1995-11-30
Abstract: The invention relates to a two-way insert valve with an insert assembly which can be fitted in a drilling and a valve cover to close said drilling. The insert assembly has a two-piece bush with several radial passages and a small axial passage and a ring fitted between the bush and the valve cover, and a valve piston by means of which a connection between the radial and axial passages can be controlled and which can be pushed as far as a stop in the opening direction. The valve piston is loaded in the closing direction by a closing spring. According to the invention, in its closed position the valve piston is taken at least approximately as far as the first face of the bush facing the ring by the bush. The guidance between the valve piston and the bush, the quality of which is essentially determined by the ratio between the guide distance and the guide diameter, is thus still sufficiently good if the radial passages through the bush and the diameter of the valve piston are very large in order to obtain large aperture cross-sections of the valve and hence low flow resistance.

Patent DE-19603036-A1 (DE)
Title: Economic plasticisation of plastic granules and complete or preshredded plastic products
Inventor: KAEUFER HELMUT PROF DR
IPC: B29C48/03
Filed: 1996-01-29
Abstract: A process for plasticising plastic granules as well as complete or pre-shredded plastic components and semi-finished products involves preheating the materials to their softening region before and/or during transport to either a screw extruder (22) or injection moulding machine (24). Heating is effected in one or more stages (10,12) which integrate the usual processing stages, e.g. drying, with plasticisation and utilise various different energy-saving methods. At the screw machine (22,24) the prewarmed materials are immediately plasticised by mechanical energy in a shortened feed section of the compression zone or where increased throughput is required processed in a less shortened or non-shortened feed zone. Continuous material flow in the screw machine can be ensured by various measures (20) at the feed zone. Preferably process stages such as screw plasticisation and/or milling are eliminated when processing fully homogenised materials, e.g. components of one type or production scrap. Initial material heating is by hot air, irradiation or similar type of system and can be carried out either: (a) in a drying and/or metering unit: (b) by utilising waste heat from the screw machine to assist the preheating or (c) by the use of directly supplied heat, e.g. from a gas burner. The plastic may be heated outside the screw machine to a temperature below the softening region and then processed in a screw machine with a grooved feed zone.

Patent DE-19619996-A1 (DE)
Inventor: HAPPEL WERNER DIPL ING
IPC: H04Q3/66
Filed: 1996-05-17
Abstract: The proposal is for a process for distributing engagement requests depending on direction in two-way trunk groups switched between computer-controlled switching devices in speech and data networks. This traffic management process makes it possible on the one hand to ensure the full efficiency of a two-way trunk group and on the other not to affect traffic in the other direction adversely or even suppress it. A ratio for the distribution of traffic in the outgoing and incoming directions is fed into the switching devices (VE A and VE B) for the two-way trunk groups connecting them. The distribution ratio (TV) is directed towards the proportions of traffic normally flowing in the outgoing and incoming directions. The engagement requests and direction of engagement of each line in the trunk group are constantly monitored by each of the two switching devices (VE A and VE B). As long as one line in the group is free, both switching devices (VE A and VE B) can occupy the lines as required by the engagement requests received. If only one line is free, the actual distribution ratio (Ist-TV) is considered and the rated distribution ratio (Soll-TV) provided is adapted.
