Abstract: 1,054,962. Hydraulic turbines. SOC. DES FORGES ET ATELIERS DU CREUSOT. April 9, 1964 [April 9, 1963], No.14690/64. Heading F1T. A system for changing over a Kaplan turbine from normal operation to idle operation with no load on a driven electric generator 16 comprises a sluice gate 15 and pivotal runner and guide vanes 1, 6 respectively. Tripping of the generator 16 closes contact 56 and initiates closing of sluice gate 15 by electric motor 21, rotation of which is controlled by an order transmitter 20 driven by electric motor 19 in response to the head across the turbine measured by pickups 17, 18: Simultaneously cam 51 begins to rotate causing abutment 38 on pivoted arm 39 to move upwards under the action of servo-piston 53. Contact 63 then closes and pivoted arm 42 on the guide vane control unit 11 is forced upwards so as to limit the opening of the guide vanes 6. Closure of contacts 63 causes piston 36 and rod 37 of actuator unit 35 to move downwards to urge pivoted arm 24 of the runner vane control unit 4 into a position corresponding to full opening of the runner vanes 1. A spring connection 31 in the linkage between arm 24 and guide vane servo-piston 8 enables this movement of arm 24 to be performed without a corresponding movement of the guide vanes 6. A similar spring connection 50 is provided between arm 42 and arm 46 on the turbine governor 45. When the sluice gate 15 has been lowered to a position dependent on the head, contact 59 closes and contact 56 opens to restore stops 37, 38 to their initial positions so that non-independent control of vanes 1, 6 is resumed under the action of governor 45. The point at which sluice gate contact 59 closes is determined by an additional rack 60 whose position is adjusted in dependence upon the head.

Abstract: 1,084,067. Fuel injection systems. DAIMLER-BENZ A. G. March 15, 1966 [March 17, 1965; March 25, 1965], No. 11288/66. Heading F1B. A device 1 between a fuel injection pump and injection nozzle controls pilot injection. At each injection pulse from the pump a piston 2 is driven down to cause pilot injection through outlet 5 until an annular groove 15 on the piston connects space 6 to a relief passage 16, terminating pilot injection. Main injection starts when shoulder 21 travels downwards beyond the shoulder 22. A throttle orifice 11 in the piston assists upward return of the piston when injection ends, the orifice being by-passed in the main injection phase by a space 14 co-operating with large diameter bores 13 in the piston. In a modification Fig. 5 (not shown) a lateral passage 25 controlled by the piston leads to the fuel nozzle and upward return of the piston is facilitated by fuel supply pressure supplied to space 6' through non-return valve 30. A non- return valve 29 is also provided in the pressure relief passage 17. In Fig.9 (not shown) pressure relief between the pilot and main injection phases is obtained by connecting space 133 through groove 119 in the piston to a passage 117 connected through non-return valve 125 to a fuel storage space 111.

Abstract: 1,228,953. Automatic train control. CROUZET. 14 March, 1968 [15 March, 1967], No. 12380/68. Heading B7N. [Also in Division G3] In an automatic train control arrangement, co-operating track and train apparatus provide an indication of the speed of the train and also a signal which steps forward a programme device whereby the actual and programmed speed of the train are compared to provide an error signal which is applied with a signal indicative of the existing position of the train speed control manipulator to a matrix circuit and thus determines whether a manipulator position change is necessary. The manipulator may have ten positions-three traction level positions, one neutral or " coast " position and six positions controlling different degrees of braking. The track apparatus includes a line conductor 1 with alternate sections D1, D2 &c., so arranged, Fig. 1, that they carry current in opposite directions. Pick-up coils 2, 2<SP>1</SP> on the train when passing from one section to the next are thus energized in antiphase for a time period which is a function of the speed of the train. The outputs from the coils 2, 2<SP>1</SP> are amplified 3, 3<SP>1</SP> and limited 4, 4<SP>1</SP> and then combined in unit 5 which supplies an output signal only when the signals picked up are in antiphase. This signal opens a gate 7, to allow a number of pulses, which are a function of the actual speed to pass from a pulse generator 6 to a two-way counter 8. The signal also steps a punch tape programmer 9 and this supplies a number of pulses which are a function of programme speed to the counter. The counter supplies a signal on the lines X which is a function of the difference between the speeds. The lines X are connected to the matrix 12 with the lines from manipulator 11 indicative of its current position and in addition where the matrix 12 is a cubic matrix lines from programme unit 10 are connected indicative of the programmed position of the manipulator. The matrix supplies an output to control the position of the manipulator and operates to reduce the number of changes to a minimum.

Abstract: 1,253,254. Transistor amplifiers. INTERNATIONAL BUSINESS MACHINES CORP. 15 Jan., 1969 [17 Jan., 1968], No. 2355/69. Addition to 1,252,661. Heading H3T. In a transistor amplifier of the type in which the current in a transistor 31 is stabilized by means of a diode-connected transistor 32 in series with the emitter and two diode-connected transistors 36, 37 in series across the baseemitter circuit of 31 and the diode-connected transistor 32, a driver transistor 33 is connected to the common point of transistors 32 and 37. The input signal is applied to driver transistor 33 via terminal 57 and an emitter follower 34. This controls the current to the output terminal 38 of the amplifier, feedback being provided through networks 42, 43. A further network 41 may be provided, the two networks 41, 42 determining the frequency and/or transient response of the amplifier. If the feedback path includes a series capacitance (Fig. 4, not shown) the resistor 21 may be omitted. The output stage is driven by a differential circuit comprising transistors 2, 3 to which input signals are fed by transistors 1 and 4. The resistor 10 defines a unit of current which flows to a diode-connected transistor 6. As the base circuits of transistors 5 and 6 are similar, the base currents are equal, and thus also the collector currents so that the collector current of transistor 5, which constitutes the combined emitter current for transistors 2 and 3 are also of one unit value. The one unit current in resistor 10 flows as a half unit in each of the diode-connected transistors 8 and 9 so that transistor 7 constitutes a half unit constant current supply for transistor 2. For symmetry, a diode-connected transistor 14 is connected in the collector circuit of the other differential amplifier transistor 3. The output from the collector of transistor 2 is fed via transistor 20 to the input transistor 34 of the output stage. A connection to the diodeconnected transistors 8, 9 ensures that the constant current source 35 in the output unit 30 also carries a half unit current. When the output voltage is to be offset, the current defining resistor 10 may be replaced by a potentiometer arrangement (Fig. 2, not shown) and when strobing is required a transistor may be connected to a tapping on resistor 10 so as to connect it to earth and unbalance the amplifier.
