Title: Sound quality improver for headphone sound - simulates normal loudspeaker room reflections using acoustic delay line tubes and mixing amplifiers
IPC: H04S1/00
Filed: 1980-11-24
Abstract: The device improves sound reproduced from e.g. two channels of a stereo system earphones, and uses two inputs coupled to repective miniature loudspeakers. The acoustic signals are transmitted along acoustic tubes to receiver microphones. Each loudspeaker is coupled to both microphones, the tubes acting as delay lines. The two microphone outputs are passed through a respective amplifier, in which the gain is frequency dependent, to respective first summing circuits which also receive the input signal to the associated loudspeaker and a third signal from a phase inverter amplifier of frequency dependent gain. This amplifier receives a signal from a third summing circuit which receives the input signals to the two loudspeakers. The first summing circuits provide the device outputs.

Title: Line protection breaker with automatic trip indicator - uses cranked arm operated by automatic trip mechanism to raise lever under operating lever and close contacts
Inventor: BOKER GUNTER
IPC: H01H71/46
Filed: 1981-01-22
Abstract: The system gives a display indicating that it is opened only after an automatic trip due to overvoltage or overcurrent on the line. Under manual operation a switch lever (3) pivoted on a pin (2), has an operating rod (1) connected to it. The operating rod has a cupped end (1a) which pushes a lever (4) with a slotted pivot hole (4a) against a fixed contact (7) closing the electric circuit. Manual opening of the circuit moves the operating rod away from the lever which then opens the circuit under spring (6) force. The push rod slides along the top of a cranked arm (8) which is in its lower position. When a fault occurs the cranked arm is moved round its pivot (9) so that it pushes the operating rod (1) clear of the contact lever (4), allowing the spring (6) to move the contact lever and open the contacts. A spring attached to the operating lever (3) draws the operating rod along the top of the cranked arm, now in its high position, so the operating rod closes contacts (11,12) placed above its path. These contacts activate a signalling device.

Title: Light emitting diode assembly with optical sampler - has photodiode receiver mounted on coupling ring around optical fibre transmitting output
Inventor: AURIA LUIGI D
IPC: G02B6/42
Filed: 1981-04-06
Abstract: An optical fibre (2) in a sheath (3) has its end facing the emissive surface (8) of a photodiode mounted on a metallised area (9) on a base (11). A metallised area (16) around the emitting face is connected to a connecting pin (131) which passes through the base.
