Abstract: A homing system guides a missile (10) towards a metal target. The missile is provided with a radar unit (12) to transmit a radar signal of predetermined frequency, and a tracking antenna (14) which scans a predetermined search pattern to receive a reflected radar signal from the target. Missile guidance and control means (51) respond to error signals to correct the flight path of the missile. The system includes a local oscillator (68) connected to a multiplier (70) for generating fundamental and harmonic reference frequencies. The received radar signal is split into two channels each including a filter (18, 20), a demodulator (22, 24) and a detector (34, 40). The output of the detector in the harmonic frequency channel is integrated (56) and supplied to a threshold detector (58). A switch (44) selectively connects the output of the fundamental and harmonic frequency detectors to an error signal generating circuit for producing the error signals. The switch is actuated when the integrated signal of the received harmonic frequency exceeds a predetermined threshold.

Abstract: A pulse detection circuit receiving two encoder output signals (A, B) which are shifted in phase with each other contains rise-up detectors (20, 22), fall-down detectors (21, 23), and gates (24-31) and two or-gates (32, 33). Combining the states of the two encoder output signals (A,B) with pulses derived from the rise-up and the fall-down edges of the encoder output signals (A,B) leads to four different possible combinations of modes in one period of the encoder shaft rotation. These four combinations of modes produced during a rotation in one direction are different from those combinations produced during a rotation in the opposite direction. 
     Counting with high accuracy will be performed even if noise is included in the encoder output signals (A, B) or if the phase relation between the two signals (A, B) is temporarily inverted.

Abstract: A succession of seamless tubular garment blanks 11 are knitted integrally on a cylindrical knitting machine, each blank 11 including at one end thereof a welt or selvedge 12 forming part of a knitted elasticated portion 13 which is destined to form an elasticated waistband in the finished garment. The elasticated portion 13 is separated from the next succeeding blank 11 by a steam-soluble draw thread 14. After knitting, the blanks are flattened, pre-shrunk and separated in a single steam-treatment operation. An end of each blank remote from portion 13 is then shaped by a cutting machine, and the blank centre-crease folded in a conventional manner. Because the welt or selvedge 12 of each blank is knitted in finished form, there is no need for a separate hemming operation and the make-up of the garment is therefore improved.
