Title: Apparatus for automatically controlling a machine tool
IPC: G05B19/18
Filed: 1971-10-13
Abstract: 1343999 Programmed control of machine tools SIEMENS AG 13 Oct 1971 [28 Oct 1970] 47726/71 Heading G3N An apparatus for automatically controlling a machine tool comprises a device for producing an indication when the residual travel path of the tool is less than p times a preset travel step, where p is an integral number, the arrangement being such that, in response to said indication, the residual path of travel is sub-divided in p further travel steps which are equal or approximately equal. As shown, a limit switch 6 activates an interpolator to release for each travel step a pulse train to an electro-hydraulic stepping motor 7 driving the tool. The pulse train is also fed to count down a counter 2, which is preset to the total length of travel of the tool, and to a steplength counter 4. At the end of a step the residual count in counter 2 is set into a counter 3 and compared in a device 5 with the contents of the counter 4. When at the end of a step the state of the register 3 is less than a predetermined number p times the state of the counter 4, an order is given by the device 5 for the reduction of the step length. The transmission of the state of the counter 2 into the register 3 being blocked by opening a switch 8 for the next step. In the next step the interpolator 1 issues pulses until p times the constant residual value of the counter 3. This is repeated until the end of the machining operation. The remaining path is thus divided into p parts. The final step being a few per cent smaller than the other steps since the interpolator 1 is stopped when the value O is reached in the counter 2.

As shown the hood baffles 20a 20b are each pivotally attached to the hood and are movable from a vertical 1 or inclined position to a horizontal (working) position. Aprons 10c, 10d extend downwardly from the longitudinal edges of the hood and the hood baffles. The overall length of the hood and its baffles is such as in one working position (shown in Fig. 4) to extend beyond the length of the quench car and over its baffles 25a, 25b. In this position all the fumes are confined within the hood. In other working positions such as shown in Figs. 3 and 5, any air entering the hood say in the direction y under the effect of wind, is confined therein and removed with the fumes via the fume extraction system. The baffles 20a, 20b and also at their lower edges the hood side walls 10a, 10b are all shaped, so as to permit passage thereunder with only a working clearance, of the quench car locomotive 24 (see references 22, 23, Fig. 2), and the baffles 25a, 25b on the coke car are correspondingly shaped so that they provide a substantially windproof enclosure with the hood and/or hood baffles. The baffles 25a and 25b on the car 9 are pivotable to a vertical position used when the car is under the quench tower or is standing idle.

Abstract: 1,142,835. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. 31 Oct., 1966, No. 48616/66. Heading H4K. In a multi-exchange system wherein each exchange is provided with a mimic diagram of the system and a network of order wires links the exchanges, each wire contains a probabilistic gate (e.g. 26 on link 33) which in effect delays the transmission of a path seeking pulse therethrough in dependence on the traffic load on the associated trunks. Whenever an intermediate exchange receives such a pulse on one of its incoming order wires, further pulse reception on any of its incoming order wires is inhibited and the pulse is passed on to its outgoing order wires (the necessary gates are disclosed in Fig. 3, not shown). At the required exchange, reception of the pulse causes a throughpath, comprising relays, to be switched through and lamps on the mimic board at the originating exchange to be illuminated so as to provide a visual display of the chosen route. If a path seeking pulse does not reach the wanted exchange (either at all or within a preset time) the system is reset and another pulse is transmitted. The probabilistic gates (also called adaptive elements) utilize stochastic integrators and are described with reference to Fig. 1, (not shown). The choice of route may be influenced by economic considerations and to allow for this actual delay circuits may be inserted in the order wires. It is suggested that the method of route finding may be used in a computer controlled system.
