Abstract: A fastening arrangement is for fastening two objects together and includes a plastic flange and a screw. The plastic flange is formed on a first object and bears on a second object. The screw includes a screw head and a threaded shank. The plastic flange defines a through-opening through which the threaded shank of the screw is guided and is screwed into a corresponding threaded bore in the second object, such that an underside of the screw head bears on a bearing region at an edge of the through-opening on the plastic flange. A first corrugation profile is defined on the bearing region of the plastic flange, and a harder, second corrugation profile is defined on the underside of the screw head. In the screwed state, on account of a pretensioning force, the second corrugation profile plastically and elastically deforms the first corrugation profile and brings about a force-fit engagement.

Abstract: A method is disclosed for producing an angled plug-in connector, which has an insert-molded, prefabricated busbar stack that has at least two busbars which are next to one another, are spaced apart by an insulating gap, and are made of an electrically conductive planar material. Each of the busbars includes a starting region which is in a reference plane and oriented in a reference direction, an end region which is bent out of the reference plane about a creasing angle and oriented in a transverse direction, a curved transition region from the reference direction into the transverse direction, and a bending region oriented along a bending line. The bending line is oriented, with respect to the reference direction, at a bending line angle, and the busbar stack is insert moulded between the starting region and the end region having a housing made of an electrically non-conductive plastics material.

Abstract: A connecting arrangement includes a first plastic component, a second plastic component, and a closed induction ring that is arranged between the first and second plastic components in a joining gap that is partially filled with molten plastic. The first plastic component has a first joining region that is configured as a stepped receiving opening with a first joining contour. The second plastic component has a second joining region that is configured as a stepped shoulder with a second joining contour. The second joining region is inserted into the first joining region to form the joining gap. The first and second joining contours are adapted to one another so as to center the first joining region, the second joining region, and the induction ring in the joining gap with respect to one another. A method in one embodiment includes welding the first and second plastic components of the connecting arrangement.

Abstract: Disclosed is a device for reducing the combustion instabilities of a combustion engine, this device including: an intake circuit admitting oxidizing air to the engine, a valve positioned on the engine oxidizing air intake circuit and designed to regulate the flow rate of oxidant gas admitted to the engine, an exhaust gas recirculation circuit connected to the intake circuit upstream of the oxidizing air flow rate regulating valve. The device is arranged in such a way that, at least when an injection of fuel to the engine is cut off, a minimum opening of the valve is assured so as to eliminate recirculated gases from the intake circuit.

Abstract: A process for the separation of volatile material from particulate polymer discharged from a polymerisation reactor in the form of a polymer slurry and which has been substantially freed from unreacted monomer in an earlier separation step, comprising (a) feeding the particulate polymer to a purge vessel and causing it to move through the vessel in substantially plug-flow mode, (b) heating the particulate polymer in the purge vessel to a temperature greater than 30° C.

Abstract: A process for the separation of volatile material from particulate polymer which has been substantially freed from unreacted monomer in an earlier separation step, comprising (a) feeding the particulate polymer to a purge vessel, optionally causing it to move through the vessel in substantially plug-flow mode, (b) heating the particulate polymer in the purge vessel to a temperature grater than 30° C. but insufficiently high to cause the particles to become agglomerated, and/or maintaining the polymer at a temperature in this range in the purge vessel, (c) feeding gas to the purge vessel counter-current to the movement of the particulate polymer to remove volatile material therefrom, (d) removing the particulate polymer from the purge vessel, wherein substantially all of the heating of the particles which occurs in the purge vessel is accomplished by preheating the gas fed into the purge vessel.

A cutting device is arranged at the output of this purge valve so as to be able to cut a continuous stream of polymer at the output of the purge valve into blocks. A conveying device, preferably hydraulic, is arranged at the output of the cutting device, so as to transport the blocks in a flow of liquid and convey them away from the discharge zone of the purge valve. The hydraulic conveying device preferably includes a chute equipped with a liquid-injection device, and a channel equipped with a device for creating a strong flow of liquid in the channel.
