Patent EP-0276776-A2 (EP)
Inventor: BOTTLE DIETRICH
IPC: H04L12/54
Filed: 1988-01-22
Abstract: A digital switching network is disclosed in which paths can be preset from any inlet to any outlet either for circuit-switched connections or for packet-switched messages (packets), as required. At any point in time, the paths preset for the packet-switched messages form a network whose nodes lie in the switching facilities of the switching network. The switching facilities contain the functional units required to switch each data packet on the path preset for it. This makes it possible to dynamically divide a single switching network into a circuit-switching network and a packet-switching network as required.

Abstract: A split tire mold having a tread ring in which provi­sion is made for venting air circumferentially across the inner surface of the tread ring so that the air escapes from the parting line of the mold halves, dispenses with widely used, conventional, radially protruding vent stubs. The air is vented through "butterfly-shaped" or "double-­wedge-shaped" arch-vents which provide passage for trapped air above each tread block of the tread as it is moved against the inner surface of the tread ring. The shape of the arch-vent passages and the angulation of the wedges is critical to the effectiveness of the arch-vent which forms an arch-vent bridge of cured rubber in a cured tire. The configuration of the bridge allows a cured tire to be easily removed from the mold cavity without leaving a broken-off piece of the rubber bridge to plug the arch-­vents. This arch-vent design leaves unobtrusive flat-­sided, narrow wedge-shaped pieces of rubber as the arch-­vent stubs, tapered in two directions. The arch-vent stubs, when viewed in the radial direction towards the center of the tire, are so unobtrusive as to be cosmetic­ally acceptable in a finished tire. The upper surface of the arch-vent is close to the inner surface of the tread ring and essentially horizontal, while the lower surface of each arch-vent is inclined at an angle in the range from 30°-50° to the horizontal plane, but in opposite directions. An angle in this range provides surprising strength in the base area of the arch-vent stub so that, upon stripping the tire from the mold, the arch-vent bridge of cured rubber breaks cleanly and reliably at the narrowest and weakest point in the bridge.

Abstract: Two bar code sensors (8)(9) are disposed at opposite sides of a passage of a photographic film (2), each bar code sensor (8),(9) having two photosensors juxtaposed along the line perpendicular to the transportation direction of a photographic film. Each time a photographic film (2) is fed by a predetermined distance, signals outputted from the two bar code sensor units are sampled and compared with the signals obtained at the second preceding sampling timing to convert them into binary signals. Based on the the data configuration of binary signals, e.g., i.e., based on the the discrimination between the start code and end code, or the presence or absence of a clock track, automatic discrimination is performed between a DX bar code (6) data and frame number (4) bar code data which are then decoded into a film type and frame number, respectively. The setting conditions of a photographic film can also be determined based on the bar code data configuration. An alarm is made if the setting conditions are not normal. The feed amount of a read-out frame number code is measured to calculate the number of a frame set at the print stage. Reading a frame number bar code may be performed in synchro with reading the DX bar code clock track.
