Abstract: 1,228,643. Logic circuits. COMPAGNIE DES COMPTEURS. 23 May, 1968 [1 June, 1967], No. 24631/68. Heading H3T. Logic apparatus liable to malfunction in response to excessively low bias voltage has a threshold and output circuit 2-8 and 15-20 responsive to values of the bias supply below the threshold for providing a control signal to prevent malfunction of the logic apparatus and the control signal is maintained for an interval following increase of the supply above the threshold value by a delay means 12, 14. As shown, the logic apparatus which may be monostable, bistable or memory circuits, is connected to bias supply 100, 101 and is controlled via one or more outputs S 1 , S 2 . The output So may be connected to the base of an output transistor of a logic circuit. With the input supply at its normal value Ua, Zener diodes 15 and 2 and transistors 18 and 5 are on and transistors 20 and 7 are off, so that no control output is given at S 1 , S 2 . When the input voltage Ua (Fig. 4, not shown) falls below Un, Zener diode 15 turns off. This turns transistors 18 and 5 off and 20, 7 on, so that a control input is fed via diodes D 1 , D 2  to the logic circuits which are held in a determined state such as to lock, delay or set them in a preferred state in the case of monostable or bistable circuits or to block a memory. Zener diode 2 remains on until the voltage Va falls below Vn after a delay determined by the capacitor 14 and resistor 12. When the input. supply Ua is again increased above the value Un Zener diode 15 turns on as does transistor 18 and transistor 20 turns off. Transistor 5 does not turn on until the voltage Va has increased above Vn (at time t 2 ) when Zener diode 2 turns on. Then transistor 7 turns off and the control signal to the logic circuit at S 1 , S 2  is removed. The capacitor 14 and resistor 12 delay the rate of increase of the voltage Va. A Zener diode 13 regulates the supply Va. In an alternative embodiment (Fig. 1, not shown), using only circuit section B of Fig. 2 a diode (10) and capacitor (9) shunt the resistor 3 and Zener diode 2, resistor 4 so as to provide delay in removing the control signal at S 1 , S 2  but the diode (10) and a resistor (11) allow rapid discharge of the capacitor (9) when the voltage Va falls below Vn.

Abstract: 1,231,149. Machine tools. 'CLYDESIDE MACHINE TOOL CO. Ltd. 27 Jan., 1969, No. 4425/69. Heading B3N. A device for the attachment of tapping tools or studs to a vertical drilling machine comprises a shank 10 for attachment to a vertical drilling machine, the shank drivingly carrying a cylindrical body 11 which has within it an adapter 22 in which a tool e.g. tap 27 can be engaged. The adapter is driven via clutch means which comprises teeth (25), Fig. 4 (not shown), on the adapter and teeth 14 which are driven by resilient pads 15 which are held positioned by a sleeve 16a. Balls 18 engage in an annular recess 23 and allow free limited axial movement of the adapter relative to the body 11. In operation, after a first entry into a given hole removal of the tool will be followed by the adapter falling to its lowest position. Thus on a next entry into the hole the tool initially, although the adapter will be rotated, will have no end thrust on it thus allowing the tool to mesh with the top of the thread already tapped. Variation in the slip value of the clutch can be achieved by using an adapter having a greater engagement depth between the clutch teeth, or by rotating sleeve 16a such that the shaped inner face of the sleeve gives a different resiliency to the pads 15.
