Title: Machine for automatically feeding warp threads.
Inventor: WILHELM HANS
IPC: G05B19/042
Filed: 1990-09-26
Abstract: The feeding machine (SE) has a feed component, means for handling the individual components and a control stage (SM) for the machine's various functions. Said control stage consists of modules (PM, SM, XM, AM) for the various functions in which the individual modules form reliable, independent units and are interconnected via interfaces. The modules are controlled by a computer overriding the control stage via which the transverse connections between the individual modules also pass. The fact that the modules are autonomous provides greater redundancy in the individual functions and allows them to be individually controlled. Thus the individual functions are interdependent to only a reduced extent and faults can be easily located.

Abstract: A global communications system is described having terrestrial transmitters (1108) for transmitting coded message signals in each of a plurality of geographic areas (1102, 1104, 1106). The global communication system further includes at least one satellite transmitter (1114) for transmitting the coded messages signals in each of a plurality of global geographic areas. The coded message signals transmissions include channel identification codewords identifying the terrestrial channels and the satellite channel. The terrestrial channel is selected for operation when the channel identification codeword received matches a first predetermined channel identification codeword. The satellite channel is selected for operation when the channel identification codeword does not match a second predetermined channel identification codeword. The terrestrial channel is periodically reselected when the channel identification codeword received on the satellite channel matches the second predetermined channel identification codeword.

Abstract: Procédé de production de pneus crus, dans lequel une carcasse cylindrique est créée sur la circonférence d'une partie formant un pneu cru pourvue de formeurs d'épaulement droit et gauche comportant des dispositifs de verrouillage de talon dont le diamètre peut se dilater. Pendant que les formeurs d'épaulement droit et gauche sont dans un état où ils peuvent se déplacer librement de manière à s'approcher ou à s'écarter l'un de l'autre, on provoque l'augmentation du diamètre des dispositifs de verrouillage de talon pour verrouiller les talons. Les formeurs d'épaulement droit et gauche sont alors commutés dans un état où ils peuvent être entraînés, et la carcasse est façonnée en une forme toroïdale tandis que les deux formeurs d'épaulement sont entraînés dans un sens où ils se rapprochent l'un de l'autre pour réunir les talons. On décrit également un appareil permettant d'exécuter ce procédé.

Abstract: The traditional drawing device used in the production of drawn ground bars is replaced by a continuous drawing and grinding device consisting of a first die, at least one grinding cutter and a second die. 
     In this way it is possible to operate with only one treatment line which treats a rough-rolled feed and produces a drawn, ground product which can also be obtained in the form of a long coil instead of short pieces only a few metres in length. 
     Another advantage is the fact that by appropriate arrangement of the cutters bars of any cross- sectional shape can be obtained.
