Title: Circuit arrangement for telecommunications switching systems, in particular telephone PABX systems designed as brokers' systems
Inventor: STEUER MANFRED DIPL ING
IPC: H04M3/60
Filed: 1986-03-08
Abstract: In the present circuit arrangement, a common audio-frequency receiver or an electro-acoustic transducer assigned to an answering set can be connected via the central switching network of the switching system to external lines which are in the hold condition. The connections take place in short-time cyclic succession in order to ascertain whether signals are present on the external line concerned which require an immediate changeover from the hold to the call condition. If signals of this type are identified, special call signals can be generated. During the cyclic activation of an electro-acoustic transducer, signals arriving on the line which has just been activated can be directly intercepted, whereupon the activation process can be stopped by means of an operating procedure in order to set up a direct call connection.

Title: Circuit arrangement for videotex operation in telephone branch exchanges, particularly key-type and executive-secretary systems
Inventor: BURKHARDT STEFAN
IPC: H04M11/08
Filed: 1986-07-16
Abstract: If it is intended to equip a telephone exchange for videotex operation, only one separate videotex decoder is in each case allocated to the individual telephone sensors which are involved. At the telephone branch exchange, only the same number of devices required for the videotex operation, for example subscriber line unit, videotex modem, as the number of videotex connections to be simultaneously set up is connected. From a videotex decoder directly interconnected with in each case one videotex modem, an audio frequency signal is generated with the aid of a special interface circuit, which signal is connected, via the switching network of the telephone branch exchange, through to the telephone terminal carrying out the videotex connection. If the videotex modem is allocated to a telephone terminal, the associated videotex decoder is responsible both for the relevant telephone terminal and for interaction with the videotex modem.

Title: Process for producing a boot
Inventor: GUTTMANN ERICH RAIMUND DR
IPC: B29D35/06
Filed: 1987-04-10
Abstract: The damping effect of boots has hitherto been achieved by special sole profiles. The disadvantage of this is that, during normal walking, the feeling virtually of floating was experienced. The object of the invention is to produce a safety boot whose elasticity in the event of impact-like loads is still present even after long service life. The boot according to the invention has an upper 1 of plastic on which preferably a steel insert 2 is applied on the walking surface. A recess 6 in the heel 5 of the sole 4 receives a wedge 3 which consists of a much more elastic material then the sole material. The invention allows the test conditions for safety boots to be fulfilled. The wedge in the heel region consists of a rubber compound. Said rubber compound is composed of a rubber proportion with 60-80% of butadiene-styrene rubber and 20-40% of high-styrene resin. 20-60 parts by weight of filler are added to this rubber proportion. To achieve a microporous structure, a dinitrosopentamethylene-tetraamine deodorised with polycondensed urea is added to this rubber compound. <IMAGE>
