Title: Dry-spinning esp. acrylonitrile! polymer from soln. - and removing solvent having given dielectric constant using EM radiation with given frequency
Inventor: PIEPER CHRISTIAN DR
IPC: D01D5/04
Filed: 1980-11-04
Abstract: Filaments and foils are dry-spun from fibre-forming polymer solns. in a solvent having dielectric constant 5-100. Novelty consists in removing the solvent from the filaments and foils with electromagnetic radiation having frequency 10 MHz to 10 GHz, and energy 0-2-20 Kw.hr./kg fibres. Process use for spinning acrylonitrile polymer solns. in DMF is claimed. (i) Standard dry-spinning velocities are used. (ii) The gaseous medium surrounding the filaments need not be heated. (iii) Energy consumption is reduced. (iv) The solvent is removed completely. (v) Round, rather than lenticular, filaments are obtd., using standard spinning jets. The filaments have high drawability, e.g. 1:15 in boiling water.

Title: Metal foreign body detection for steel reinforced conveyor belt - compares properties of belt before and after delivery of conveyed material
Inventor: KLUENDER REINHARD DIPL ING
IPC: G01V3/11
Filed: 1980-12-06
Abstract: The detection of metal foreign bodies within material deposited on a steel wire reinforced conveyor belt is effected using two detectors (1,2) continuously measuring the same characteristic of the conveyor belt and placed upstream and downstream of the material deposition point. The detectors (1,2) are coupled to a comparator (3) which supplies a control signal (4) when their difference varies from a reference value. The comparator (3) may compensate for detected rotational variations of the non-driven conveyor drum (5). The conveyor belt may be used to deliver rubbish to a bagging station with metal foreign bodies detected within the rubbish fed onto the belt to allow their removal preventing damage to the conveyor belt.

Title: Search head for missile for monitoring solid angle - has electromagnetically-driven scanning element inside head for active guidance onto target marked with laser illuminator
Inventor: SIEBECKER HANS DIPL ING DR
IPC: G01S3/789
Filed: 1980-12-12
Abstract: The electromagnetic radiation from the target and its surroundings enters through the window in the search head, is then split up by a polygonal mirror and diverted by additional mirrors onto an outer polygonal mirror. The radiation then passes via an objective to a receiving element integrated into a Dewar flask cooled by gaseous nitrogen. The preamplifier and signal processing electronics are arranged around the Dewar flask in the form of a cylindrical tube. The scanning element inside the infra red search head covers an azimuthal angle of about plus or minus 25 degrees to plus or minus 40 degrees. The search head is operated in a passive mode, the missile being guided to the target by the heat radiation. The end phase of the flight continues in active guidance by the aimer, by marking the target with a laser target illuminator.

Title: Conveyor roller for support of belt or goods - has end-support bearings held within vibration-absorbing resilient rings
Inventor: DUTTINE WALTER
IPC: F16C13/02
Filed: 1980-12-20
Abstract: Rollers are supported by shafts fixed to side members of a conveyor frame. The rollers may define a track for the articles to be conveyed or may serve to guide a belt. Members serving as the outer races of bearings for each roller are held in resilient support rings. Members serving as the inner races constitute journals arranged to support the roller from the side members of the conveyor. The resilient support rings, pref. of rubber or plastics, damp sound vibrations and restrict transmission from the outer casing of the roller to the journals. The resilience of the supports also permits subsequent correction of the alignment of a support roller relative to the side members.

Title: Arrangement for setting the rotation speed of asynchronous machines
Inventor: THAMM SIEGFRIED PROF DR
IPC: H02P23/06
Filed: 1981-04-03
Abstract: The invention relates to an indirect converter for setting the rotation speed of asynchronous machines. The aim of the invention is to be able to keep low the cost of smoothing means which are required in the design of a DC voltage or direct-current intermediate circuit for voltage stabilisation and for impressing a current. The invention is based on the object of creating an indirect converter for setting the rotation speed of asynchronous machines, in order to implement an unlimited rotation-speed control range, of varying the magnitude of the mean value of the intermediate-circuit voltage impressed on the machine-side converter or of the intermediate-circuit current impressed on the machine-side converter over a likewise unlimited control range, without influencing the magnitude of the voltage of the commutation capacitors of the machine-side converter and thus its commutation capability by the magnitude of the mean value of the intermediate-circuit voltage impressed on the machine-side converter or of the intermediate-circuit current impressed on the machine-side converter. According to the invention, an intermediate-circuit voltage is impressed on the machine-side converter, which intermediate-circuit voltage varies cyclically in time, whose peak value is essentially constant and whose mean value is adjustable. <IMAGE>

Patent DE-3123753-A1 (DE)
Title: Friction false twister
Inventor: OBERSTRASS DETLEV
IPC: D02G1/08
Filed: 1981-06-15
Abstract: A friction false twister consists of two discs moved relative to one another in the overlap region and having parallel or slightly staggered axes of rotation. The discs are so arranged with their axles in mountings that the distance between the two discs and/or their position in relation to the yarn running through between them is variable. The discs form a twisting region on the side facing the yarn running through. For this, at least one of the two discs is movable in a cardanic manner on its axle, in that it consists, for example, of a flexible or pliable, but tension-resistant material. A pressing-down device serves for ensuring good yarn contact. As a result of the geometrical positioning of the pressing-down device, on the one hand, and the disc mountings, on the other hand, in relation to one another and by the adjustment of other operating parameters, such as the yarn speed, rotational speed of the discs and pressing force of the pressing-down device, the best possible operating conditions, including the twisting direction, can be set.

Title: Roller mounting with adjustable axial bearing play
Inventor: HAENSEL HELMUT DIPL ING
IPC: F16C13/02
Filed: 1981-10-21
Abstract: In conventional band-conveyor or moving-pavement rollers, when the individual parts are being assembled, because the cumulative longitudinal tolerances of the individual parts are superposed there is an axial play which is troublesome in terms of production and which cannot be prevented, but at most can be kept small. Admittedly, the play can be controlled by selective parts or by a machining operation included in the assembly process, nevertheless these are measures which, if not actually harmful, involve a high outlay. The patent is concerned with a solution for this state of affairs. The tolerance compensation is provided on one side, in that a two-part or three-part compensating element (a set of tapered rings) is pushed over the axle and up against the inner ring of the ball-bearing, a kind of claw then lying supportively against one flank of the round groove of the axle. As a result of a thread-like rotation of the tapered rings until they bear firmly against one another, the total play in the longitudinal direction is eliminated. The state obtained can be safeguarded by means of an anaerobic adhesive between the tapered rings and the axle or additionally by a pushed-over ring provided with corrugation.
