Abstract: The present invention relates to a process of linking the operation of a fabrication machine for envelopes and a conditioning machine by utilizing a movable device which in case of mal-functioning, may be short-circuited in favor of a classical system which is already present in fabrication machines for envelopes. This linking device is characterized by the association of an element of the chain, in particular a pivoting selection finger which, besides its task to retain the first envelopes of the subsequent lot also assures a liable guiding of the previous lot of envelopes towards the belt transporter, with a driving device for the envelopes including a mobile bar which is driven by a motor which is controlled by a counter permitting the control of the exact number of envelopes per lot, as well as the association of said two members with a pivoting distributor provided for changing the orientation of the envelopes and for disposing said envelopes in horizontal orientation onto said belt transporter comprising catch studs.

Abstract: An apparatus for marking the back of a photographic proof with data corresponding to data on the corresponding negatives in a system where the negatives are on a film strip having at each negative an edge notch and the proofs are on a print strip having spaced cutouts comprises a film drive for advancing same from the upstream to the downstream drive roll past a read location. A sensor detects the film-advance speed and generates an output corresponding thereto. A print drive advances this strip past a write location. Another sensor detects the paper-advance speed and generates an output corresponding thereto. A controller is connected to at least one of the drives and to the sensors for synchronizing displacement of the strips past the respective locations such that each proof is at the write location generally when the respective negative is at the read location. Another detector generates an output each time a notch is in a predetermined position at the read location. Another read head at the read location triggered through the controller by the notch detector each time the exposure data of the respective negative is in the read location reads this data. Another detector generates an output each time a cutout is in a predetermined position at the write location. A write head at the write location triggered through the controller by the cutout detector each time the print is aligned with the write head marks the back of the print strip with the exposure data read by the read head on the respective negative.

Abstract: At least one out of a group of threads of the same running length (L1 or L2) is monitored continuously for thread tension, between leaving the creel frame and winding on the winding machine. Measured- and desired values are compared. When a departure is detected, thread brakes of the relevant group are adjusted, causing the actual value to approach the desired value. An Independent claim is included for the corresponding creel frame for a winding plant. Preferred features: Thread brakes (18) of each thread group having the same running length, are controlled by a common- or an individual drive motor (20). For each thread group having the same running length, actual thread tensions are measured on two or more threads, to determine a mean for comparison with the desired value. A further variant of the method based on the foregoing principles is described. Thread brakes of a vertical row of spooling locations are adjusted by a common drive motor. Further variants of the plant, based on the foregoing principles, are also claimed.

Abstract: A method and a device for conditioning electric installations in buildings for the rapid transmission of data produces symmetrical transmissions paths, along which high frequency signals can be transmitted with substantially no interference, using low-level emission. By introducing an inductance coil into the neutral conductor, as closely as possible to the earth point of the building, the conductor becomes insulated for high frequencies whereas the remaining conductors constitute the high-frequency earth. The high-frequency communication signals are transmitted between the neutral conductor and the protective conductor. This produces transmission channels with relatively good symmetry and negligible interference, which permit a significantly improved exploitation of resources.
