Title: Telephone circuit
Inventor: ASHWORTH DAVID
IPC: H04M19/08
Filed: 1985-11-02
Abstract: Modern telephones often include electronics which needs a low current supply when the telephone is on-hook. This is usually supplied via a bleed resistor which by-passes the hook-switch when on-hook. This has disadvantages, so the present invention overcomes these disadvantages by replacing it with a constant-current active circuit using transistors and resistors. The constant current circuit uses two transistors (T1 and T2) and two resistors (R1 and R2), connected as shown. <IMAGE>

Title: Controlling a spinning machine
Inventor: GORN IGOR VLADIMIROVICH
IPC: D01H13/32
Filed: 1986-07-16
Abstract: A spinning machine has a first control loop which consists of measuring the current output of the whole machine and the speed of the machine (eg the speed of the spindles and drafting heads) and adjusting the machine speed to maximize productivity.
