Patent GB-2103697-A (GB)
Title: Key-retaining lock
Inventor: TWIST ROLAND WILLIAM JOHN
IPC: E05B11/02
Filed: 1981-07-09
Abstract: A security lock, for instance for a car park barrier, is key-operated and the key can only be removed when (a) the lock is in a locked state as a result of (b) the barrier being properly engaged with the lock. The boltable element, e.g. a tongue 3 on the barrier, enters a housing. A bolt 6 can engage the tongue to prevent withdrawal, or can free it. A lock mechanism controls movement of the bolt, by operation of a key 5 which can only be removed and inserted when the mechanism is in locked state. When the tongue is not in the casing, a spring-loaded detent 9 prevents rotation of the bolt 6 into its fastening position, thus ensuring that the key is trapped in the lock insertion of tongue 3, e.g. by lowering the barrier, displaces the detent 9 from its blocking position and allows bolt 6 to rotate about axis A...A to lock the tongue and also to allow the key to be freed. <IMAGE>

Title: Digital frequency discriminator
Inventor: RICHARDSON CHRISTOPHER KEITH
IPC: H03L7/187
Filed: 1983-09-14
Abstract: A digital frequency discriminator operative to provide a discriminator output signal in dependence upon the frequency difference between a pulsed input signal and a pulsed reference signal comprising a voltage controlled monostable device (20) connected in a feedback loop so that the duration of its monostable pulses is controlled by a control voltage (39) to correspond with the pulse period of the pulsed reference (32) signal and which is triggered by each pulse of the pulsed input signal (19) to produce the monostable pulses and comparator means (22,28,29) responsive contemporaneously to pulses of the pulsed input signal and to the monostable pulses for producing the discriminator output signal. The digital state of the digital output signal, (0 or 1), is determined in dependence upon the pulse length of pulses of the pulsed input signal as compared with the pulse length of corresponding pulses of the pulsed reference signal. Known digital frequency discriminators have the disadvantage that they require several cycles of input signal in order to produce an output signal; the present digital frequency discriminator affords a digital frequency output signal which obviates the aforesaid disadvantage. <IMAGE>
