IPC: H02K7/06
Filed: 1981-04-10
Abstract: An electrically operated driving device includes a bell type armature motor with a hollow shaft containing an internal thread. An axially extending threaded spindle is located within and in threaded engagement with the shaft. The rotation of the hollow shaft is transformed into liner motion effected by the spindle. The movement of the threaded spindle relative to the hollow shaft can afford a different speed and/or a different direction of rotation. The armature is of the iron-free or ironless type. The device operates at the least weight almost inertialess, and converts the produced power without significant friction losses and it can be used in a very limited space.

Patent DE-3230481-A1 (DE)
Title: Two-component wearing material
Inventor: HEINRICI KONRAD DIPL ING
IPC: C09K3/14
Filed: 1982-08-17
Abstract: The invention is based on the object of developing a wearing material, in which highly wear-resistant particles such as corundum or oxide ceramics are introduced into a base material. This is effected by plasticising the predominantly tough base material by heating and thus allowing penetration of the highly wear-resistant particles. This two-component wearing material can be adapted to the particular use requirements by a subsequent heat treatment and/or surface densification. This wearing material can be used both for frictional wear and for impact wear. Its advantages are insensitivity to shocks due to the use of tough base materials and saving of expensive alloy elements such as chromium, nickel and molybdenum.

Patent DE-3301045-A1 (DE)
Title: Automatic feeding device, in particular for aquaria
Inventor: EHEIM GUNTHER
IPC: A01K61/85
Filed: 1983-01-14
Abstract: An automatic feeding device for aquaria is proposed which has in a housing a rotatable supply drum with a feed dispensing opening, a drive device and a coupling which is situated between the latter and the supply drum and can be engaged by means of settable programme cams of a programme wheel driven in a time-keeping fashion. The drive device consists of an electric, quartz-controlled clockwork drive that is independent of the mains and whose minute drive tube, which rotates at one revolution per hour, forms the drive shaft for the supply drum and which at the same time also drives the programme wheel. The clockwork drive is fed by a battery. The programme wheel is seated directly on the 24 hour drive tube of the clockwork drive, which is constructed as a hollow shaft. The coupling consists of a grid-spring coupling. One spring end of the latter is permanently connected in terms of drive to the supply drum, while the other spring end is prevented from revolving by the catch of a spring lever, with the result that the grid-spring coupling winds up. The settable programme cams of the rotating programme wheel act on a control cam of the spring lever and trigger the latter upon engagement of the coupling.

Title: Photographic camera having a film transport and shutter-cocking device driven by an electric motor
Inventor: HOEPFNER CLEMENS
IPC: G03B17/42
Filed: 1983-01-14
Abstract: A motor (1) drives a planetary gear (5 to 8) whose internal gear (7, 7b) transports a film (12) via intermediate members (10, 12a). The film transport is blocked by a pawl (22) falling into a ratchet wheel (12, 12a) which engages with the film transport gear, as a result of which a sun wheel (8) tensions a drive member (14) via an intermediate toothed wheel (9) and a rack (14a). The drive member (14) is transferred to the tensioned position, in which it is separated from the intermediate wheel (9) by pivoting, against the force of a tension spring (17). In this case, the motor circuit-breaker (16) is switched off and the drive member (14) is stopped at a release lever (23). The release lever (23) releases the drive member (14) in order to drive a leaf shutter (19). In this case, the pawl (20) comes out of engagement with the ratchet wheel (11), the drive member (14, 14a) pivots into engagement with the intermediate wheel (9) and the motor (1) is switched on via the motor circuit-breaker (16). The tension spring (17) is guided by fixed deflecting pins (18, 24) in such a way that depending on its extended length it acts either essentially only in the longitudinal direction of the drive member (14) or else transverse thereto thereon. <IMAGE>

Title: Apparatus for reversing flexible flat-shaped articles joined together in bag form
Inventor: GLASOW GUNTHARD
IPC: D06G3/02
Filed: 1983-02-14
Abstract: The invention relates to the treatment of textiles and other flexible materials, especially the reversal of textile flat-shaped articles joined together in bag form. The aim of the invention is to reverse the flexible flat-shaped articles in bag form into a position suitable for use. The object is to increase the operating reliability of the apparatus, make the guidance and handling of the reversing article more reliable and to prevent creasing. This is achieved in that the reversing elements in the form of an arc of a circle are thickened in a pear-shaped manner on the receiving ends and have obliquely outward-directed air-outlet ports and spreading bars. Guide elements are provided between the reversing elements in parallel with the path of movement of the latter. Provided on the reversing elements and on the apparatus is a series of clamping and holding devices which guarantee a reliable guidance of the reversing article. Moreover, a stripping element can move into and out of the path of movement of the reversing elements and an air-blowing strip for conveying the reversed article away is provided. Sectors of use are the laundry and upholstered-furniture manufacturing industries. <IMAGE>

Title: Bearing for rotary drums
Inventor: KOERTING REINHARD DIPL ING
IPC: F27B7/22
Filed: 1983-02-25
Abstract: A bearing (1) for the rotatable supporting of, in particular, thermally stressed rotary drums (2) of large dimensions comprises a saddle-shaped receptacle (3) which can be pivoted about an axis (3a) extending transversely to the vertical longitudinal centre plane (2a) of the rotary drum and can be displaced along this axis, a number of bearing elements (4) being provided between this saddle-shaped receptacle (3) and the circumference of the rotary drum. This simple constructional configuration on the one hand permits optimum adaptation of the saddle-shaped bearing receptacle to thermal deformations of the rotary drum and, on the other hand, extremely good surface contact between the circumference of the rotary drum and the bearing elements, the large number of bearing points counteracting excessive deformations of the diameter of the rotary drum. <IMAGE>
Patent DE-3308549-A1 (DE)
Title: Closure for syphon bores
Inventor: BOETZKES KLAUS
IPC: B65D39/06
Filed: 1983-03-10
Abstract: The closing of the syphon bore is brought about by a ball-like plug (3) which consists essentially of two hemispherical end parts (22) and (23) and of a short cylindrical middle part (24). The plug is driven into the syphon bore by means of a suitable tool, in such a way that a mushroom-like head laying itself from inside against the end of the syphon bore is obtained on the closing plug. This mushroom-like head prevents the internal overpressure from forcing the plug outwards. The longer shape of the plug afforded by the middle part (24) ensures a good hold on the inner wall of the syphon bore, so that the closure is perfectly effective even in the event of an internal underpressure and unfavourable bore dimensions. <IMAGE>
Patent DE-3312842-A1 (DE)
Title: Drive device for a printing mechanism carriage which can be moved along a recording medium in the direction of the lines in typewriters or similar office machines
Inventor: CHVATLINSKY KURT
IPC: B41J19/20
Filed: 1983-04-09
Abstract: To achieve a clear typeface with even character spacings, the carriage which bears the type carrier and can be moved along the recording medium must be switched accurately. In the case of conventional typewriters, the linear movement of the carriage is effected via a stepping motor which is arranged so as to be fixed to the frame and is connected to the carriage via a toothed belt. Since, in this case, the stepping motor drives the toothed belt directly, it must be constructed to be correspondingly efficient. The invention is based on the object of providing a carriage drive device which is of simple construction, allows low-clearance and precise stepping drive and can be used for inexpensive mass products. This object is achieved in that the ends (27, 29) of a cable pull (25), which is wrapped several times around a cable drum, are firmly connected to the side walls (31, 33) of the frame, and in that the drive motor (19), which drives the cable drum, is arranged, together with the cable drum, on the printing mechanism carriage. As a result, an optimum design of a cost-effective stepping motor (19) is achieved which guarantees low-noise, almost vibration-free horizontal drive. <IMAGE>

Title: Method for producing a melting fuse, and a melting fuse
Inventor: ASDOLLAHI NORBERT DIPL ING
IPC: H01H69/02
Filed: 1983-05-06
Abstract: The invention relates to a method for producing a melting fuse, and a melting fuse in which a unit consisting of two contact plates which are electrically connected by means of a fusing conductor is fitted in an insulating body, and the contact plates are soldered to contact caps which close the insulating body. In the course of production, the contact plates are originally connected to one another via a link, which is separated once the fusing conductor has been fitted to one pair of contact plates. In an advantageous design of the fusing conductor, the unit which is formed from the contact plates and the fusing conductor is intrinsically stiff and intrinsically stable enough to be handled automatically. In comparison with melting fuses which are assigned to an insulating substrate, it is possible to select the material of the contact plates freely, and hence the characteristic of the fuse.
