Abstract: 1476159 Protective shields for winding machines MAILLEFER SA 25 Oct 1974 [26 Oct 1973] 46244/74 Heading D1J A wire winding machine of the kind having a traversing mechanism comprising a carriage 11 reciprocating along the entire length of the take-up reel 5, and carrying a pulley 13 for guiding wire 14 onto the reel 5, is characterised in that the carriage 11 carries a circular protective channel 16, 17 that is co-axial with the reel 5. The channel 6, 7 catches broken wire ends that may occur during winding. In Fig. 2 the channels 6, 7 are pivoted at 18, 19 and piston and cylinder units 21, 22 are provided to open and close the channels. Fig. 4 is a developed view of one form of the protective channel showing how the pulley 13 is aligned with a run-in channel 17c that will lead a broken wire end into channel 17b in the part 17 and thence into channel 17a in part 16. Fig. 6 is a developed view of a second form of the protective channel showing how the pulley 13 can extend into an opening in one of the channels, the opening having a pointed end 26c. After a wire-tail has passed over the pulley 13 it is picked up by the channel element 26 and follows down the middle of that element. It then passes down the middle of the element 25 until it is deflected to one side or the other by the pointed end 26c. From then --on, it follows one of the continuous circular tracks situated on each side of the plane of the pulley 13. The carriage 11 slides on guide bars 9 and is moved by a screw 11. Fig. 1 (not shown) illustrates the present invention in a continuous wire winding apparatus in which when one reel 5 is full it is swung through 180 to a doffing position at the same time as an empty reel is swung 180 into the winding position.

Title: Heat unit integrator for x-ray tubes
IPC: H05G1/36
Filed: 1975-11-17
Abstract: 1524069 Analogue simulators VARIAN ASSOCIATES Inc 17 Nov 1975 [20 Nov 1974] 47333/75 Heading G4G An analogue computer simulates the thermal behaviour of an X-ray tube by multiplying signals representing cathode current and anode voltage to obtain a signal representing power which is integrated to obtain a signal representing anode temperature. In particular, both the current and voltage signals are developed as voltages referred to a common ground potential. A signal representing current is derived from a resistor in series with the tube current supply, and is fed to a differential amplifier 12 which produces at terminal 13 a voltage referred to ground potential proportional to tube current. A voltage proportional to tube voltage is derived from the primary of the tube transformer and appears at output terminal 23 of differential amplifier 12<SP>1</SP> as a voltage referred to ground potential. The current signal is corrected in an amplifier 15 having adjustable bias 18 which is set to ensure that the signal is zero when the cathode is cold. The voltage signal is corrected in an amplifier 25 having gain control adjusted according to the magnitude of the tube current whereby the characteristics of the tube transformer are compensated. A power signal developed in multiplier 21 is transmitted through gate 29 only when the tube current is above a certain minimum as determined by control circuit 42. This prevents accumulation of spurious power signals occurring during the long periods in which the tube is inactive. The power signal is fed to one of a number of integrators 45A, 45B &c., respectively appropriate to different tubes, and each having a resistive circuit 47A, 47B &c. in parallel with the integrating capacitor for simulating heat dissipation from the anode. In order to simulate an exponential cooling characteristic, the resistive circuits may include a number of parallel resistors switched by diodes responsive to the voltage on the capacitor (see, Fig. 3, which is self-explanatory). The output of the integrator represents temperature and may be fed to a display 53 or to one of a number of overload switches 51A, 51B &c. The differential amplifiers 12, 12<SP>1</SP> are identical and are shown in Fig. 2 which is self-explanatory.
