Title: Method for decision feedback clock extraction
Inventor: MANN PELZ RODOLFO DR
IPC: H04L7/02
Filed: 1993-03-13
Abstract: A method is proposed which is used for decision feedback clock extraction. The method comprises a soft output Viterbi detector and a phase detector. The soft output Viterbi detector identifies a decisive data sequence d(i) and the corresponding reliability information Ld(i) from a data sequence v(i) according to the soft output Viterbi algorithm and forwards this to the phase detector. The phase detector determines a quantity proportional to the current sampling time by comparing the time-discrete data sequences v(i) with the decisive data sequence d(i) and the corresponding reliability information Ld(i). The sampling clock and the symbol clock are defined according to the proportional quantity. <IMAGE>

Patent DE-4314121-A1 (DE)
Title: Chimney attachment for discharging, in particular, flue gases
Inventor: ZEHREN MANFRED
IPC: F23L17/02
Filed: 1993-04-29
Abstract: Known flue-gas chimneys with ventilation ducts which open beneath an expansion-joint plate have disrupted air guidance, and condensation and corrosion of the expansion-joint plate occur. The novel chimney attachment is intended to form a solid termination and provide better ventilation for the chimney. A covering plate (6) with inner ventilation chamber (18) with central opening (24) protects the upper chimney opening and ventilation ducts (9) against weathering. After the attachment of an end pipe (3) onto the covering plate (6), a plug-in pipe (2) with a collar (16) integrally formed on at the upper end, in the mounted position, is pushed through the end pipe (3) and the central opening (24) into an expansion-joint socket (4). The end pipe (3) has an internal diameter exceeding the external diameter of the plug-in pipe (2) and forms an interspace (22). It is closed towards the top since the collar (16) of the plug-in pipe (2) bears on the end pipe (3). The end pipe (3) exhibits openings (13) which penetrate its wall. Undisrupted air flow from the ventilation ducts (9) via the ventilation chamber (18), through the central opening (24), into the interspace (22) and through the openings (13) to the outside is achieved. The chimney attachment ensures sufficient ventilation of the chimney and is resistant to corrosion. Assembly is simple. <IMAGE>

Title: Screwing device with acquisition, monitoring and control of measurable screw parameters during the screwing operation and method for producing high-quality screw connections
Inventor: BAIER HEINZ ING GRAD
IPC: B23P19/06
Filed: 1993-05-15
Abstract: A screwing device is presented in which the screwing parameters, primarily the angle of rotation and the torque, which are directly measurable during the screwing operation are recorded. These parameters are supplied to a monitoring device which is able to discontinue the screwing operation in the event of an error occurring. It is also adapted to recognise the end of the screwing operation. By storing the recorded parameters - either in the case of specified tolerance overshoots or in the case of specified sequences of screwing operations - the data are made available for an error and quality control. With the recorded data, it is additionally possible to allow the screwing operation to proceed in a manner which is controlled entirely or only in specified phases with respect to the torque or the turning rate.

Title: Cutting mechanism for a wood breaker
Inventor: GREWATSCH REINHOLD DR
IPC: B02C21/02
Filed: 1994-04-15
Abstract: Known cutting mechanisms are too often geared to special applications. This makes the manufacture of these cutting mechanisms expensive. The aim consists in producing a simplified cutting geometry with a number of fitting-out variants. The countercutter (9) of the cutting mechanism is formed exclusively from circumferential surfaces, and in particular by two adjacent cutting discs (6) and an intermediate ring (10). The effective contour of the countercutter (9) is produced from the internal cutting surfaces (7) of the two cutting discs (6) and the circumferential surface of the ring (10). The cutting mechanism is used in particular in breaking machines for wood. <IMAGE>
