Title: Protecting device for a synchronous motor
IPC: H02H7/08
Filed: 1990-02-23
Abstract: The invention relates to a protecting device for a synchronous motor, for detecting an asynchronous state, caused by a mains disturbance, in which a susceptance (1 DIVIDED X) is determined from the stator current (I) and stator voltage (U), which susceptance activates a trip if a protection characteristic (s;s';t), defined by an adjustable response value ((1 DIVIDED X)e), is exceeded. If the synchronous motor is connected to an approximately constant mains voltage, then the detection of the reactive component (IB) of the stator current (I) or the reactive component (PB) of the power (P) is sufficient. With suitable adjustment of the protecting device with respect to asynchronism and lose of synchronisation as a consequence of mains disturbances, it is also possible to detect faulty under-excitation or loss of excitation of the synchronous motor. <IMAGE>

drive chain forms a torque transfer drive from the axis 
of the converter to a parallel axis coinciding with the 
axis of a geared differential (18), a pair of half shafts 
being connected to side gears of the differential for 
powering traction wheels wherein the clutch-and-brake 
system and the planetary gear units as well as the drive 
chain are integrated one with respect to the other to 
provide a minimum axial dimension with respect to the 
axis of the engine crankshaft thereby facilitating the 
packaging of the transaxle in a limited space within the 
vehicle. The torque flow path from the turbine of the 
converter through the gearing and from the gearing to the 
torque transfer drive chain is accomplished by strategi­
cally positioned torque transfer sleeve shafts surround­
ing the axis of the converter.

Title: Device for transferring single sheets to the offset cylinder of a rotary sheet-fed printing press
IPC: B41F21/00
Filed: 1991-07-05
Abstract: The device has a transfer cylinder (2) with a drum (4) which is adjustable in the circumferential direction relative to its shaft (3) and which carries sheet grippers (8) with a front stop (8a) for the sheets (B). The diameter of the transfer drum (2) is equal to 1/N of the diameter of the plate cylinder which carries N printing plates. The shaft (3) of the transfer cylinder (2) rotates at a constant speed and executes N revolutions when the plate cylinder is executing one revolution. By means of a controllable setting device, the drum (4) is so displaced relative to the shaft (3) during each revolution that the front stop (8a), when its transfer position in which a sheet is transferred to the impression cylinder (D) is passed, assumes a position by which the exact register of this sheet in relation to the position of the printing plate printing it on the plate cylinder is set. This guarantees that the width of the front margin between the sheet front edge and print start is of the same size on all the printed sheets, without the need to adjust the printing plates exactly on the plate cylinder in a time-consuming way.

Patent EP-0565314-A3 (EP)
IPC: G06Q10/10
Filed: 1993-04-01
Abstract: A method and apparatus for creating, supporting and using a travelling program is disclosed. A "travelling program" is a digital data structure which includes a sequence of instructions and associated data and which has the capability of determining at least one next destination or recipient for receiving the travelling program and for transmitting itself together with all relevant data determined by the program to the next recipient or destination. The travelling program can compute, according to any algorithm whatsoever, the digital material which is to be signed, and also, as needed, the digital material which is to be verified. The present invention also allows the program to conditionally decide, based on any known criteria, which users should participate in the signature process. The present invention also uses digital signatures to allow the travelling program to provide other types of valuable authentication. For example, as a security convenience the present invention allows for the digital signature authentication of the entire transmission from one user to another. This includes the travelling program itself, its variables, and any ancillary data or files. The present invention provides a unique mechanism for automating data collection among a group of users. The travelling program may be sent to one user, attach (or detach) relevant data files and move on to the next user. Data or files, collected from one or more users can be deposited with another user, or accumulated for batched processing as desired. This methodology eliminates the need for individual users to be counted on to transmit all the required data in the required format. The present invention also efficiently performs electronic document interchange (EDI) in the context of a travelling program which sends itself from user to the next within an organization, collecting, editing and approving data. <IMAGE>

Inventor: BALES BRUCE M
IPC: H04M1/247
Filed: 1995-12-06
Abstract: Telephone terminals directly implement an automatic call back feature
by establishing a logical channel between two telephone terminals when a calling
telephone terminal is unable to complete a call to a called telephone terminal. Via
the logical link, the called telephone terminal communicates to the calling telephone
terminal any change in state that is related to its ability to receive a call. When both
telephone terminals are idle, the calling telephone terminal recalls the called
telephone terminal to set up a call. The logical link is established on user-user
temporary signaling or D channel facilities of ISDN links. Since the interconnecting
networks are not part of providing the automatic call back service, the telephone
terminals can be interconnected by any combination of telephone networks that
provide ISDN service.

Patent EP-0722216-A3 (EP)
Inventor: BAKER CLIFFORD E
IPC: G01R15/24
Filed: 1996-01-11
Abstract: A split-path isolation amplifier (10) employs a transformer (30)
in a high path (26) and a single-input, dual-output closed-loop
optocoupler (66) in a low path (24) to achieve a flat, wide frequency
response without need for frequency compensation adjustments. In a
low path frequency region (106), the optocoupler provides all or most of
the signal to the output. The isolation amplifier employs a substantially
overlapped crossover frequency region (104) in which the high path
signal is applied to a primary winding (28) of the transformer, and the
low path signal is applied differentially to secondary windings (40, 42) of
the transformer. At frequencies below the crossover frequency range,
the signal from the optocoupler dominates as the signal coupled from
the primary winding rolls off. At frequencies above the crossover
frequency range, the signal coupled from the primary winding dominates
as the signal from the optocoupler rolls off. At frequencies within the
crossover frequency range magnetic flux components generated by the
primary and secondary transformer windings co-act to provide a
combined output signal having a flat frequency response. The only
adjustments are those required to match the gain of the low path to the
gain of the high path and to compensate for any offset in the low path.
