Elastomeric material, especially elastomeric scrap material, is subjected in a ring grinder to simultaneous grinding and peeling for separating reinforcing material and elastomeric material. The ring grinder has its inlet (12) arranged to supply grinding material substantially horizontally towards the rotor (20) of the ring grinder, and supplied elastomeric scrap material is caused to pass the maj...

The present invention relates to an apparatus for gas phase polymerisation of olefins(s), essentially comprising a fluidized bed reactor and at least one conduit for drawing off polymer provided with an isolation valve and connecting the vertical side wall of the reactor to a lock hopper, the said conduit leaving the vertical side wall of the reactor while being directed downwards so that each par...

The present invention relates to a process for continuous gas-phase polymerization of olefin(s) in a fluidized and/or mechanically stirred bed reactor, comprising a stage of drawing off the polymer out of the reactor, wherein a portion of the bed is transferred into a lock hopper and is then isolated from the reactor in the lock hopper for a period of 5 to 120 seconds so that a substantial amount ...

A novel packaging of semiconductor elements, such as MCM tiles, with a variety of printed circuit or wired boards (PWB), the packages occupying a small size, at least in the vertical direction, relative to prior art OMPAC devices. The MCM tile includes an interconnection substrate with peripheral metallizations and at least one chip or integrated circuit (IC) mounted on the substrate by solder ref...

Described is a novel packaging of MCM tiles without wire-bond interconnections and in a total thickness which is reduced relative to conventional MCM packaging. The MCM tile includes a substrate with a plurality of peripheral metallizations and at least one chip flip-chip mounted on the substrate. The PWB is provided with an aperture which is smaller than the size of the silicon substrate but larg...

An indicating apparatus for indicating a vacuum, particularly for indicating the vacuum on the filtered-air side of an air filter for an internal-combustion engine, including a housing and a piston which is movably disposed in the housing and which separates a vacuum area from an ambient-pressure area. A snap element is provided which is activated by the piston and, at a predetermined vacuum, trig...

Two heat exchangers are hooked up together in order to generate a flow of cold gas. A deep-frozen liquefied medium is evaporated in the first heat exchanger (1) by means of heat exchange with a heat transfer medium. The evaporated medium is re-cooled in the second heat exchanger. The deep-frozen liquefied cryogenic medium used for this purpose is likewise evaporated in this process. The two flows ...

The carrier frequency assigning system only allows the same carrier frequency to be assigned to different mobile stations (MS1,..MS3) when the directions of the mobile stations relative to the fixed station (BTS) differ from one another by a given min. angle and the received radio signal levels lie within defined a defined reception level range. Pref. the required difference angle between the mobi...

A dishwasher sump is divided into a collection chamber and a pump chamber by a filter. Food particles collect in the collection chamber while filtered wash liquid collects in the pump chamber. The filtered wash liquid is recycled and sprayed on objects in the dishwasher. A venturi jet pump has a suction gap located in the collection chamber and an outlet connected to a drain. At the end of a wash ...

To assign a carrier frequency to different mobile stations in a conventional Space Division Multiple Access (SDMA) radio system, the stations are differentiated according to the direction in space from which they transmit radio signals to a base station. In addition, the distances between the base station and the mobile stations are compared. To prevent interference at the receiving site (base sta...
