Patent DE-3438706-A1 (DE)
Title: Device for comminuting sheet metal and similar material
IPC: B02C13/28
Filed: 1984-10-23
Abstract: A comminuting device, in particular for sheet metal and similar material, is protected against the rotor arms breaking in that in each case two such rotor arms are arranged offset with respect to one another and form a disc-like cross rotor. This cross rotor is equipped with hammers which are held via the continuous hammer axles and can rotate freely in recesses constructed in the rotor arms. As a result, stressing of the rotor arms by impacts is avoided. Protective caps distributed over the circumference are provided between the hammers and are set back with respect to the ends of the arms which receive the hammers. These protective caps form an impact elevation which advantageously improves the comminution work without the advantages of the arm rotor being lost. By virtue of the corresponding outer shape of this cross rotor, it is in fact ensured that even parts of different sizes are reliably released again from the rotor during the comminution process. By virtue of the special shape of the cross rotor, i.e. the disc-shaped design, an advantageous centrifugal mass is present by means of which the comminution process is further promoted.

Title: Magnetic holder for removable dental prostheses
Inventor: SPRUNK JOHANNES DIPL ING
IPC: A61C13/235
Filed: 1984-11-02
Abstract: In dentistry, the removable prostheses are held on the jaw by so-called attachments and/or braces. This expensive and/or insecure fastening is replaced by permanent magnets arranged in pairs with opposite poles. One set of magnets is firmly implanted in the jaw, e.g. in crowns, while the other opposing ones are included in the removable prosthesis, so that the prosthesis is attached to the jaw by magnetic force. The magnets comprise materials which are very well tolerated by the body. The prostheses provided with these are easy to handle and to clean, and they thus improve oral hygiene of the wearer. This is particularly favourable to the elderly (both from a physiological viewpoint and in financial respects) because the overall prosthetic expenditure is lower and costs are thereby reduced.

Patent DE-3509576-A1 (DE)
Title: Vane water meter
Inventor: WAWRETSCHKA GUENTER
IPC: G01F1/08
Filed: 1985-03-16
Abstract: In the vane water meter, the vane wheel cup is provided with an inlet duct, which debouches tangentially into the vane cup measuring chamber, and, facing it, with an outlet duct issuing tangentially. In order to adjust the error curve, the vane wheel cup has a bypass duct, which branches off at the inlet duct, has a regulating screw and is designed as a circular-arc duct extending in the circumferential direction of the vane wheel cup. Said circular-arc duct debouches tangentially, between the inlet and outlet duct of the vane wheel cup, counter to the direction of rotation of the vane wheel, into the vane cup measuring chamber. As a result, regulation of the water meter is effected not only through the bypass quantity of water passing through the bypass duct, but there is also formed, in the circular-arc duct, a water branch-stream which is counter to the direction of rotation of the vane wheel and which impinges onto the edge zone of the vane wheel pallets and thus transmits a hydraulic pressure moment to the vane wheel. Depending on the depth of engagement of the regulating screw, said pressure moment varies, so that by virtue of this additional counter-flow regulation the running speed of the vane wheel can be influenced to a considerably higher degree than hitherto.

Title: Movement mechanism for a starting aid and for a driving aid of motor vehicles
Inventor: UNGER GERHARD RUDOLF DIPL PHYS
IPC: B60B39/12
Filed: 1985-06-04
Abstract: Movement mechanism for a starting aid and for a driving aid for motor vehicles for road traffic on traffic routes covered with snow and ice, which movement mechanism itself lays carriageways by means of driven wheels as in a caterpillar vehicle. A belt (12) made of a mesh or a belt made of a coarse fabric or of a wrappable carpet surface with a web carrier made of rubber-like material between the tyre (21) of the wheel and the surface (F) of the carriageway is laid as a rolling travel surface for each driven wheel (2) by means of belt-guiding means, consisting of in each case two rotatable belt winding reels (31, 32) which are borne by two shafts (33) or of at least one deflection roller, which can be rotated about an axle, for a continuous belt which rests continuously against the tyre of the wheel, or by means of belt attachment means with which a continuous belt continuously rests securely on the tread surface (211) over the circumference of the tyre of the wheel. The reel shafts (33) or roller axles are aligned parallel to the axis of rotation of the wheel and attached to the motor vehicle. In addition, in each case one belt-guiding roller (52) is attached as belt-guiding means to the ends of two bolts (5) which project out under the motor vehicle just in front of and just behind each driven wheel (2) perpendicularly to the surface (F) of the carriageway. <IMAGE>
Patent DE-3526007-A1 (DE)
Title: DC motor without a commutator
Inventor: DOEMEN BENNO
IPC: H02P6/15
Filed: 1985-07-20
Abstract: In the case of a two-strand, two-pulse DC motor (10) without a commutator, driver transistors (44, 45) are provided for the output-stage transistors (52, 53) and are connected by means of one control electrode to a potential (point 47) which, for example, is half the applied DC voltage. These driver transistors are driven with a digital signal (41) from a Hall IC (32). In order to avoid a sudden changeover from one strand (25) to the other strand (26), each driver transistor (44, 45) has its own RC element (43', 46' or 43'', 46'' respectively). Pauses without current are thus produced between successive stator current pulses, which results in relatively soft switching of the output-stage transistors, so that the motor runs quietly. <IMAGE>

Patent DE-3528380-A1 (DE)
Title: Method and device for measuring the propagation time and, if required, the amplitude of acoustic surface waves
Inventor: BRUST HANS-DETLEF
IPC: G01H5/00
Filed: 1985-08-07
Abstract: Frequency, amplitude and rate of propagation are important parameters for describing acoustic surface waves on piezoelectric crystals. It is possible by means of the method according to the invention to determine the propagation time of a pulse packet of surface waves between two measuring points or between one measuring point and a reflection site. It is therefore possible given a known measuring point spacing to measure the rate of propagation or given a known rate of propagation to locate the reflection site on the crystal surface. In accordance with the invention, a finger transducer is caused to transmit pulse packets of surface waves periodically, and the temporal variation of the potential contrast signal is measured at one or more measuring points. Because of the low bandwidth of the signal chain of a scanning electron microscope, these measurements cannot, however, be carried out in real time. In order nevertheless to achieve a high time resolution, use if made of a sampling method. The measurement sensitivity can be substantially increased if the respective measured value is averaged over a plurality of measurement cycles in order to improve the signal-to-noise ratio. Although it is true that because of the nonlinearity of the potential contrast line the signal level is not proportional to the actual surface potential and thus to the elongation of the wave, the maxima of the measurement signal thus obtained are sure to be points of the same phase whose temporal spacing can be precisely measured. <IMAGE>
