Abstract: The present disclosure describes a process and an apparatus for delivery of plastic at a viscosity and in the required quantity suitable for compression molding of large, and often odd shaped three-dimensional products, such as large automotive body parts and large appliance parts, etc. These products may consist of plastic only, or may require additional layers of other plastics or even other materials such as woven cloth, inserted into the cavity before molding. The purpose of this invention is to provide a process and apparatus for use with a compression molding machine to supply plastic to a mold cavity, at a number of suitable locations, and in appropriate quantity at each location as required by product shape and thickness. The apparatus and process includes a delivery head which is mounted on rails attached to the machine clamp or the mold cavity, and a connection between the injection unit of the molding machine.

Abstract: The test facility tests whether the services subscribed to by a user in a subscribed network are also available in a visited network. Because the network functions and services should be tested in the same way as a customer actually uses them, they preferably have to be tested from the subscriber network interfaces. The subscriber network interfaces are especially important at the air interface and at the switched network for conventional analogue and ISDN telephone services (Integrated Services Digital Network). However, for special tests internal interfaces of a GSM network (Global System for Mobile Communication) are also of significance such as the A-Interface at the Mobile Switching Center (MSC) of a GSM network.

Abstract: Method and device for measuring the transmission quality in cells of mobile radio networks in which, using a mobile station (MS) comprising a GPS receiver, the cell to be measured is travelled through, and the geographic position and the time are recorded at specified intervals. The signals transmitted from a base transmission station (BTS) to the mobile station as well as a call build-up signal sent at certain intervals, are stored with the GPS position. Furthermore, signals between the base transmission station and the respective mobile station, which signals are sent at specified intervals, are recorded with time stamps by means of a mobile radio analysis device (MA). Subsequently there is a mixing together of the recorded data of the mobile station with the recorded data of the mobile radio analysis device, sorted according to time stamp, with the measured results issued by geographic position and by time.

Abstract: A mattress is provided with a plurality of inflatable cushion elements each having two cushion chambers. Air or filling pressure medium can be regulated by a device with a pump. The pump is coupled to a control in which filling pressure values and/or arithmetical operations are programmed. The pump is also provided with sensors. This enables the filling pressure to be increased or reduced on the basis of the weight of a lying person loading the cushion elements until a predetermined value corresponding to a specific degree of hardness or comfort for lying is attained. Simple pressure on a key on a remote control is therefore sufficient to bring about completely automatic adaptation to the lying person, regardless of whether he or she weighs 40 or 150 kg. This intelligent mattress offers an absolute maximum of individual comfort for lying with a minimum of effort for operation.
