Title: Rolling mill housing contg. multiple work rolls - which are arranged in circular row round workpiece, and can be used for rolling or drawing
Inventor: KOSTOGRYZOV IGOR D
IPC: B21B13/10
Filed: 1980-07-16
Abstract: The workpiece travels through a rolling gap formed by a circular row of equispaced rolls, e.g. three, four or six rolls. Each roll is free to rotate on a shaft which intersects with the other roll shafts inside a housing. One end of each shaft consists of a boss with a hole in which another end of another shaft is located, e.g. so the axes of all the rolls are in a single vertical plane. The end of each roll shaft opposite the boss has a screw thread for a nut; and the nuts clamp the assembly together. Several assemblies may be mounted in a row, e.g. as in a stretch- reducing mill; and the rolls may be idling or driven. Useful for rolling small sections in steel or Cu alloys, e.g. rod, tube or profiles. When the rolls are free to rotate on their shafts, the workpiece is drawn through the roll gap.

Title: Homogenising and pelletising cellulose ether - by cutting, shock and shear effect, pelletising and drying
Inventor: GRIMM RAINER ING GRAD
IPC: C08B11/20
Filed: 1980-08-30
Abstract: In the continuous homogenisation and pelletisation of crude cellulose ethers, followed by drying, a cellulose ether with 35-45wt.% moisture content is subjected to the effects of cutting, shock and shear and homogenised, then pelletised and finally dried. Opt., the cutting, shock and shear action is carried out at the same time as the pelletisation. The moisture content may be adjusted by use of hot gases, e.g. air or N2, by addn. of water, or by addn. of superheated steam with simultaneous drying. Finely divided alkali salts may be mixed with the cellulose ether, to act as extenders, and to reduce the active content of the ether. The process is simple, and economical in appts. and energy. The particles are uniform, and their structure and density are controllable and can be adjusted w.r.t. the drying process.

Title: Method for a telephone station with a twelve-key keypad in centrally controlled telecommunications systems, in particular telephone PABX systems
Inventor: SCHOEN SIEGFRIED
IPC: H04Q3/62
Filed: 1981-08-06
Abstract: The invention relates to a method for a telephone station with special keys for subscriber services in a centrally controlled PABX system. For specific subscriber services, a plurality of keys need to be actuated at defined time intervals. The intended object of the invention is to implement subscriber services of this type with only one key actuation without time monitoring. The object is achieved in that, in order to implement a subscriber service of this type (e.g. call-back), information, including time monitoring, which is allocated to this service and which can be fed in by means of a plurality of key actuations of the PABX system is stored in a memory space of the read-only memory of the calling subscriber station and is transmitted from this memory space through the actuation of only one special key via an existing connection or via a new connection which is to be set up with the aid of the allocated memory contents when the special key is actuated. This produces the advantage that only one key needs to be actuated for the complete input of a subscriber service, this key being assigned to this subscriber service only and therefore being able to be labelled accordingly. The method can be applied to all telephone stations in centrally controlled systems.

The foot board is folded by means of two joints in such a way that the rear, roller-shaped wheels produce with the front wheel, which has a pneumatic tyre, a stable three-point bearing and so give rise to a special transportation means which is considerably reduced in its external dimensions and can be used without difficulty in businesses and on public transport. The advantages achieved by means of the invention consist mainly in the fact that the user can move relatively quickly by means of his own muscle force and at the same time convey everyday items. <IMAGE>
Patent DE-3139021-A1 (DE)
Title: Soundwave absorbing frame
Inventor: MAASER ARNFRIED
IPC: G10K11/00
Filed: 1981-09-28
Abstract: Loudspeaker enclosures, television sets and so forth are intended for acoustic reproduction. When these devices are taken into operation, the loudspeaker diaphragms generate waves or soundwaves. Loudspeaker diaphragms are in most cases integrated into wooden or plastic housings. When the diaphragm begins to work, the soundwaves are transferred to the housing and the environment and surrounding objects. To prevent this, the stand has the small support area of the hemisphere and the foam layer located underneath and the compact base of a non-transmitting material (see attached drawing). This prevents the housing resonances (extraneous resonances) from being transmitted and results in an improvement in the sound (acoustic improvement). <IMAGE>
