Title: Improvements in or relating to analog-to-digital converters
IPC: H04B14/04
Filed: 1966-05-27
Abstract: 1,128,256. Analogue-to-digital converters. SIEMENS A.G. 27 May, 1966 [28 May, 1965 (2)], No. 23852/66. Heading G4H. An analogue-to-digital converter - comprises a number of encoder stages, equal to the number of digits in the outputs, the stages being arranged in series and each comprising a decision circuit and a store, the first stage receiving the signal to be converted, the polarity of the signal being determined by the decision circuit and a signal.equal to half the digit value being added to, or subtracted from the stored signal according to the polarity, the resulting signal passing to the next stage where the; process is repeated. The'form of Fig. 1 has three stages. The input Si is tested by the decision circuit E1 to determine whether it is positive or negative. If it is-negative a value of half the value of the digit is added, and if positive, the same value is subtracted. The store Tp1 stores the signal Si on a capacitor, the value A/2 being applied to the-output. The resulting signal is doubled at V1 and applied to store Tp2 and decision circuit E2. The same value A/2 is then added to or subtracted from the stored signal as before depending on its polarity, and the resulting signal is doubled again at V2 The decision circuit E3 again determines the polarity. The outputs of the three decision circuits indicate in binary scale the value of the input Si. In the form of Fig. 3 the input signal Si is sampled by a switch operated by clock pulses To and the samples are stored on capacitor Co. The output from capacitor Co is applied through amplifier V1 and a switch operated by clock pulses T1 to store C1 It is also applied through amplifier TV1 to decision circuit E1 detecting the polarity as before and applying a positive or negative signal through amplifier TV1<SP>1</SP> to be added to the output from capacitor C1 amplified at V 1<SP>1</SP>. The gain of the whole stage is 2. The next phase is similar. For greater accuracy the circuits may be made symmetrical, there being two capacitors storing the outputs of a differential amplifier with a centre earth connection. The binary outputs of the decision circuits may be all gated out together and serialized by a delay line train. The switches are diodes and their capacitances may be neutralized by -cross-connections between the two arms of the symmetrical circuits. Inductive coils may be provided to form, with the capacitors. resonant circuits designed to charge the capacitors as rapidly as possible. The amplifiers may be transistors circuits. High impedance input circuits to the differential amplifiers are described. The stores may comprise inductances instead of capacitances.

Abstract: 1,009,662. Clutch control; friction clutches. USLAV PRO VYZKUM MOTOROVYCH VOZIDEL. June 20, 1963 [July 3, 1962], No. 24559/63. Headings F2C and F2L. A temperature responsive control for a friction clutch 2, 3 between a driving pulley 4 and an engine cooling fan 6 comprises a temperature sensitive element 17 in the water coolant system 31 that controls a valve 24 to supply pressure air from a reservoir 30 to a clutch disengaging servo 13, 14, 15 below a predetermined temperature, and above that temperature exhausts the servo whereupon springs 8 engage the clutch 2, 3. Below the predetermined temperature the valve spool 23 is in its lower position wherein it connects a pressure air supply port 26 to a clutch disengaging port 27 and closes a clutch exhaust port 28. As the temperate rises the element 17 acts against a return spring 19 to compress an adjustably prestressed spring 21. When the force of the spring 21 overcomes the air pressure acting on the end of the valve spool 23, the latter is moved rapidly up to the position shown wherein it closes the clutch disengaging port 27 and opens the exhaust port 28. On a fall in temperature the element 17 permits the return spring 19 to tension the spring 21 until the latter overcomes the air pressure on a flange F of the valve spool 23 whereupon the valve spool is moved rapidly down. A lamp 34 operated by an air pressure switch 33 indicates when the fan is in operation. In Fig. 8 (not shown) the spring 21 is replaced by a spring lever. Friction clutch.-The clutch disc 3 is urged by springs 8 in a hub 5 of the fan 6 into engagement with the clutch disc 2 fast with the pulley 4, and the disc 3 is connected by rods 9 to the disengaging servo housing 14, 15. A flexible diaphragm 13 of the servo bears against the fan hub 5 so that when pressure air is supplied through a line 10 and connector 32 to the servo, the housing 14, 15 moves left together with the rods 9 and clutch disc 3. The rods 9 are connected to the hub 5 by tangential spring strips (Figs. 2 and 3, not shown) or by a flexible ring (Figs. 4 and 5, not shown).

Abstract: 643,834. Automatic regulation; running generators in parallel. BRITISH THOMSONHOUSTON CO., Ltd. - Sept. 22, 1948, No. 24799. Convention date, Sept. 27, 1947. [Class 38 (iv)] In an engine-driven electric generating system the setting of an engine speed governor is adjusted automatically in Accordance with a regulating signal dependent on the value of a variable load on the generator and an opposing signal dependent on. the governor position. The generator supplies with other generators an A.C. network and the regulating system of the generator is arranged to deal individually with a heavy Fluctuating load on the network. As shown, the network 2 is supplied by a generator 1 driven by a turbine 4, the steam supply of which is regulated by a valve 5 controlled by a ball-governor driven by the turbine. The setting of the governor is also controlled through gearing 7, 10, 11 by a motor 9 driven by an amplidyne which is responsive to the output of a network 14, 16, 17 controlled in accordance with the power supply to a load 3 and normally balanced for the basic load on the network by the adjustable tapping 22 of the voltage transformer 15. The network is controlled in accordance with the load current by the voltage across a resistor 23, fluctuations of the load 3 causing unbalance of the currents in the field windings 18, 19 of the amplidyne 20 and adjustment of the governor 6 to cause load compensation in the turbine. A feed-back of the position of the governor is transmitted by a Selsyn 25 to rebalance the network 14, 16, 17. The system thus provides an anticipatory regulating action for dealing with fluctuating loads whilst at the same time permitting the normal speed regulations for basic load changes on the network.
