Title: String mounting for stringed instruments
Inventor: MARINIC JOSIP
IPC: G10H3/18
Filed: 1986-06-13
Abstract: String mounting for stringed instruments with at least one string (1) which is mounted vibratably and tunably and the vibration length (L) of which is defined by two string bearings (2, 3) which are arranged at a spacing from one another and the first (2) of which is arranged at one end of the instrument body (4) or of a neck connected rigidly thereto, and the second (3) of which is arranged at the other end of the body (4) and is designed as a bridge. Accommodated in the bridge (3) are, corresponding to the number of strings, piezoelectric sensors in the form of prismatic piezo-bodies (8) with a bottom-side and a top-side contact surface and, covering these, pressure pieces (9), and the strings (1) guided via the pressure pieces (9) transmit their vibration forces via the pressure pieces to the piezoelectric sensors (8) for generating corresponding electric signals. The bridge (3) is equipped with means in the form of an additional bridge (13) or for achieving a suitable fastening (plane 14, angle  gamma ) in such a manner that the force vectors p of the string vibration forces run in a direction which is normal or virtually normal to the contact surfaces of the respective piezo-body (8). The support height of the additional bridge (13) is lower by a small amount (a1) than that of the bridge (3). <IMAGE>

Title: Contact arrangement for a withdrawable power circuit breaker
Inventor: KRAFFT HENNING DIPL ING
IPC: H02B11/127
Filed: 1986-06-28
Abstract: In the case of power circuit breakers which are withdrawable from switching installations, problems relating to the structural depth, the door seal in the case of a tube which is moved by the door, in the case of interlocks and in the articulation on the circuit breaker occur as a result of the different positions of the withdrawable unit. Furthermore, the entire insertion force is transferred to the circuit breaker. In order to overcome these difficulties, according to the invention, the power circuit breaker (1) is pushed into a predetermined final position and the on-test-off positions are reached via a contact frame (7), which has contact links (22) and is displaced horizontally by means of a drive lever (8). <IMAGE>
Patent DE-3636393-A1 (DE)
Title: Positive clamping set for connecting a hub to a shaft
Inventor: PETER OSKAR E
IPC: F16D1/091
Filed: 1986-10-25
Abstract: The invention relates to a positive clamping set with a centring ring for hub connection. In clamping sets, the fundamental principle is that an inner and an outer ring are pressed onto the shaft and into the hub, respectively, by axial clamping exerted by tapered surfaces in order to connect them frictionally for rotation in common. In the case of notched ring surfaces there is also positive engagement and this predominates over the frictional engagement. In the case of positive clamping sets, there was the difficulty of evening out the pressing action in the axial direction in order to achieve as high as possible a transmissible torque even in the case of dynamic shock loads. The invention achieves this by means of a double-taper thrust ring between the inner and the outer ring in the main clamping region as the first clamping element and by means of taper heads in corresponding recesses in the inner and the outer ring, in their thick-walled region, as additional clamping elements (Fig.1). The taper heads, which are attached to the centring ring, simultaneously serve as a coupling between the inner and the outer ring and thereby prevent relative rotation between them. <IMAGE>

Patent DE-3702416-A1 (DE)
Title: Waveguide switch
Inventor: HETTLAGE ECKART DIPL ING
IPC: H01P1/12
Filed: 1987-01-28
Abstract: A waveguide switch having four outputs and/or inputs A, B, C, D normally has a rotor with three passages by means of which two waveguide connections can in each case be produced in specific rotor positions. In two switching positions, only the centre waveguide passage passes RF signals, while the two curved passages (4, 5) simultaneously carry RF signals in the two other switching positions. While the transmission losses in the centre passage are very low, until now, very high reflection occurred in the two curved passages, as a result of the bend points. In order to improve the transmission properties, it is proposed according to the invention to construct the curved passages in an elliptical shape. For this purpose, the longitudinal passage (3) is tapered towards the rotor centre so that sufficient space is created for the curved path of the side passages. The circular shape of the curved passages 4, 5 can also be approximated by designing the walls like facets. The bend points 8 and 9 produced in this case thus produce only an insignificant change in the transmission properties. <IMAGE>

Patent DE-3726413-A1 (DE)
Title: Electronically commutated DC motor having a fixing device for fixing the permanent magnets
Inventor: DIERKES ALBERT DIPL ING
IPC: H02K1/27
Filed: 1987-08-07
Abstract: In the case of electronically commutated DC motors, good smooth-running properties are also dependent on the exactly radially symmetrical arrangement of the permanent magnets. Conventionally, said permanent magnets are bonded or cast to a load-bearing element of the motor. This connection is not detachable, as the result of which an elastic fixing device in the form of a cage is known for fixing the magnets in the radial and axial directions. Its disadvantage is an unfavourably large separation between the permanent magnets and a stationary rotor-position detector. The proposed fixing device (13) in contrast has a closed end ring (15) and retaining webs (14) which project forwards from said ring in the axial direction and, in pairs, each hold one of the permanent magnets (9) between them. These retaining webs (14) carry the radially projecting latching tabs (16) which engage in a prestressed manner in a groove (17) provided in the load-bearing element (1). In addition, at the free end, the retaining webs have fixing projections (18) which protrude in the circumferential direction and engage around the permanent magnets (9) in such a manner that their end surfaces (20) and those of the retaining webs lie approximately in the same radial plane. Electronically commutated DC motors for precision drives, for example as disc drives for computer memories. <IMAGE>

Patent DE-3804509-A1 (DE)
Inventor: BERTSCH-FRANK BIRGIT DR
IPC: C01B15/12
Filed: 1988-02-13
Abstract: Spray-drying of a solution containing hydrogen peroxide and sodium metaborate is known per se; these products are very fine and amorphous, and they show an unsatisfactory storage stability. 
<??>According to the invention, these disadvantages are eliminated, if the primary particles obtained by spray-drying are, immediately after they have left the drying zone, fed to a granulator device and granulated in the presence of free water and/or water of crystallisation of the perborate and, if necessary, the granules are dried. The generally amorphous primary particles are converted into granules having an at least partially crystalline structure and a significantly improved storage stability. Advantageously, the process is carried out in a spray drier with integrated fluidised bed or in a compacting granulator device. The process is suitable for producing perborate granules with more than 10 % by weight, especially perborate monohydrate granules with 14 - 16 % by weight, of active oxygen.
