The Key-Lock security recording system announced by VeederRoot Ltd. permits unsupervised, individually recorded 24-hoursa-day refuelling or product dispensing. Designed for vehicle fleet operators, transport departments and so on, the KeyLock allows deliveries to be made only to holders of special keys when connected to a cornpany's petrol pump. Such deliveries are totalled accum ulatively on internal counters against the particular key used to operate the system. Any number of individual counters up to 254 per console (each with its own special key) can be provided.
The recording console can besited in any convenient position, if necessary away from the loading point. The system can also be used to record and initiate the loading or dispensing operation of a variety of bulk cargoes such as liquid chemicals, foodstuffs and grain, ready-mixed cement and so on.
The special tamper-proof lock can be incorporated in the recording console: for applications in explosive or inflammatory areas a fully flameproofed lock built to the Ministry of Power Buxton standard is available which, for example. enables the lock to be mounted direct on a petrol pump. It is similar to a conventional Yale-type tumbler lock except that an additional section, containing electrical switches, is provided.
Each key has two sections, a Yale section to release the lock and a coded section to operate the electrical switches. For any one installation, the lock section is identical on all keys, whereas the coded section is particular to each separate key. The equipment cannot be operated unless the lock section of the key matches the lock. When it does match, the key will turn the lock and the key's individually coded section ensures that delivery amounts are accumulatively totalled on the counter corresponding to the particular key used.
The system operates on a normal 230V 50 Hz supply. A three-phase contactor is provided for petrol-pump motor operation, and the whole equipment is housed in a rugged, lockable weatherproof stoveenamelled steel cabinet, the size of which varies with the number of different keys, and thus counters, required. For vehicle re-fuelling applications, the installation would be handled by the users' petrol-pump manufacturer.
