Abstract: An electronic hand-held, talking learning aid 1 is disclosed. The learning aid includes an MOS speech synthesizer chip having an active surface area of the order of 45,000 square mils. The speech synthesizer chip includes a digital filter, a voiced/unvoiced excitation circuit, a speech parameter interpolator, an input parameter decoder, a digital-to-analogue converter and associated timing circuits. The learning aid is also provided with a micro-processor which functions as a controller for controlling the operation of the unit. A small speaker is driven by the digital-to- analogue converter on the speech synthesizer chip and a keyboard 3 and a display 2 are strobed by the microprocessor controller. In a first, spelling, mode, a question is posed via the speaker and an answer entered via the keyboard by the operator is compared with the correct answer, a resultant response being given via the speaker. In a second mode the operator is shown a word via the display and asked to speak it; after a delay the correct pronunciation is produced by the learning aid via the speaker. In a third mode, a word is selected for display, but certain letters are omitted, leaving the operator to complete the word. In third and fourth modes, respectively, encoding/decoding of words and generation of a random word are performed. <IMAGE>

Title: Active capacitor coupling for two amplifier stages - employing FET connected to coupling capacitor to enable use of greatly reduced capacitance value
Inventor: KRAUSE GERHARD
IPC: H03H11/00
Filed: 1979-06-13
Abstract: The active coupling circuit joints two stages (T1,T4) of a solid state amplifier in series. The proposed arrangement is specifically intended for use in the manufacture of integrated circuit amplifiers, and serves to reduce the surface area required for the coupling capacitor (C). The coupling capacitor (C) is connected between the input and gate terminals of a FET (T2). The gate is also connected to the output terminal through a high value resistor (R3), typically of the order of 100 megohms. The FET output forms the input to the second stage amplifier (T4). It is desirable to connect a further transistor (T3) to the second stage gate. This transistor has output and gate connected to the negative supply. The arrangement allows the use of a coupling capacitor several times smaller than normal, and thus eases manufacture on an integrated circuit chip. The geometry of the resistor (R3) and connections is arranged to give a high value of parasitic resistance (R2,R4) to earth.

Title: Domed reactor cover flaw detection - by ultrasonic transducer emitting transverse beam at adjustable down angle (NL 7.5.80)
Inventor: DIJKSTRA FREDERIK HENDRIK
IPC: G21C17/007
Filed: 1979-11-02
Abstract: The domed cover of a reactor pressure vessel with the welded vertical tubes for control and/or instrument rods is checked by an ultrasonic flaw detector for cracks.

Title: Load simulation on brake testers - is by regulating moment of inertia of test stand from speed and integrated torque
Inventor: RAPTOPOULOS PRODROMOS DIPL ING
IPC: G01L5/28
Filed: 1980-02-15
Abstract: A method of simulating loads on brake test beds involves generating the required energy with an electric motor and measurement and integration of the braking torque. It enables the desired moment of inertia of the test stand to be regulated. The integrated braking moment is divided by the difference between the output revolting rate and the instantaneous revolution rate and fed to the moment of inertia control circuit as the actual value. The output revolution rate is controlled to a value which can be adjusted. The braking torque is measured by a force sensor, amplified, and fed via an integrator (18) to a divider (20) whose other input is driven by the difference of the motor (6) tachogenerator (7) direct and sampled (19) outputs. The divider output forms the control value for the motor current.
