[Also in Division H3] Hammer impression mechanism.-An electromagnetically operated hammer mechanism 12, 16 is accelerated from its normal position by a short current pulse and the hammer effects impression by momentum and rebounds: during the return of the hammer back to its normal position the electromagnet is energized again with a damping current effective to cause deceleration. The operating current is derived from a condenser C1 which is discharged through the coil 30 of the magnet 10 via an electronic switch, e.g. silicon controlled rectifier SCR1 which is turned on by an incoming signal at 31. On turning off, current continues to flow around a loop formed by the electromagnet 30, an inductor L1 and a diode D4 so that on discharge of the condenser a loop current is set up which decays to provide the required damping. Adjustment of impact.-Individual adjustment for each hammer system is achieved by adjustment of potentiometer R5, while potentiometer R6 permits a common adjustment of all hammer systems.

Abstract: 1485514 Measuring distance electrically NIPPON KOKAN KK 13 Nov 1974 [14 Nov 1973] 49047/74 Heading G1N In order to linearize the output characteristic of an inductive type distance measuring probe a Q multiplying circuit is used. Measuring coil 4 connnected with capacitor C to form a resonant circuit is connected to a Q-multiplier in the form of amplifier 6 provided with feedback Rp and an oscillator 2 which, when the coil 4 is not influenced by conducting body 1 the distance from which is to be measured, supplies A.C. to the resonant circuit at its resonant frequency. As the distance between object 1 and coil 4 decreases both the inductance of the coil 4 and the resonant frequency of the tuned circuit, and hence its effective impedance, vary non-linearly. Since these variations of inductance and impedance are complementary it is possible by suitably adjusting the gain of the Q-multiplier to adjust the Q of the resonant circuit and thus obtain an output from amplifier 6 which increases positively linearly with increasing distance between coil 4 and object 1. Instead of using the impedance variations of the tuned circuit the variations in phase as a function of resonant frequency can be used, Fig. 6 (not shown). In this arrangement the output of the amplifier 6 is fed to a phase sensitive detector whose reference is provided by the oscillator 2. The gain of the Q-multiplier is again adjusted so that a linear phase V distance output is produced. In order to isolate the resonant circuit from the input circuit to the amplifier 6, the latter is provided with inverting and non-inverting inputs and a negative feedback is provided between the inverting input and output, Fig. 7 (not shown) and Fig. 8. Either R N  and/or R P  may be adjusted to linearize the output. In order to obviate variations in the resonant frequency of the tuned circuit to temperature effects a negative temperature coefficient resistor 8 and capacitor C' are employed.

The said deceleration or acceleration signal is added to the reference signal and the latter is obtained by modifying the vehicle speed signal by a factor corresponding to a maximum coefficient of adhesion between a wheel and a road surface in contact therewith i.e. by approximately 8. The brake pressure control unit includes a conduit 23 connected to an engine inlet manifold as a source of vacuum and a chamber 12 communicating therewith. A diaphragm piston is urged by a spring 11 to such a position that rod 14 keeps a ball valve 15 open to allow flow of hydraulic fluid to the wheel cylinders. Energization of solenoid S 1  of a valve C<SP>1</SP> cuts off communication between conduit 23 and chamber 13 via conduit 22 and allows atmospheric air to enter through a port 27 and filter 28 to move the piston 10 and close valve 15, at the same time the effective volume of chamber 17 being increased to relieve pressure in the wheel cylinder. Operation of a valve B<SP>1</SP> by means of solenoid S 2  accelerates or retards the action of the unit with energization or denergization of the solenoid. In another embodiment vehicle speed is determined by a fifth wheel.

Abstract: 1,169,964. Automatic voltage control. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Nov. 2, 1967 [Dec. 20, 1966], No. 49935/67. Heading G3R. In a D. C. to D. C. converter of the type including a switching transistor associated with a transformer from the secondary winding of which is derived a stabilized output voltage, both the impedance and the mark/space switching ratio of the transistor are controlled in dependence upon output voltage variations so that the transistor functions simultaneously as a controlled chopper and as a variable series impedance. As shown, a high voltage UA, e.g. 800V, for application to a load such as a micro-wave tube is derived from a low voltage source UB, e.g. of 24V, by way of a blocking oscillator constituted by a switching transistor T1 associated with a transformer TR including a primary winding N1, a feedback winding N3, and a secondary winding N2 having an output which is applied to the output terminals 0, 0, by way of a rectifier bridge G and a smoothing capacitor C1. The base of transistor T1 is loosely A. C. - coupled over a capacitor C2 to the feedback winding N3, and is further connected to a voltage divider constituted by resistor R1, R2 and a transistor T2, the base of which is connected over a transistor T3 to the output of a further transistor T4 associated as shown with a Zener diode Z and a voltage divider R6, R7 connected across the output terminals. In operation, when the output voltage is below a desired value transistor T1 is not fully saturated in its conductive state, because of the loose A. C. coupling with the feedback winding N3, and the switching of the transistor is dependent upon the charge/discharge cycle of the capacitor C2. When the output voltage reaches the desired value, transistors T2, T3 and T4 are also conductive but not fully saturated; variations in the output voltage from the desired value are sensed by the transistor T4 which correctively controls the impedance of transistor T1 by way of the transistors T2, T3. Further, the time constant of the discharge path of capacitor C2 changes, since this path includes the transistors T2, T3, so that the switching duty cycle of the transistor T1 is also correctively controlled so that the transistor functions simultaneously as a controlled switch and a variable series impedance.
