Title: Aircraft anti-missile radar system - re-transmits enemy radar signals to confuse missile by reflecting signal off ground
IPC: H01Q17/00
Filed: 1973-03-09
Abstract: Aircraft receives the enemy radar signals, amplifies them and transmits the signals forwards and towards the ground or sea in a direction towards the attacking missile which carries a target search radar. This signal is much stronger than the direct echo signal from the aircraft thus missile deviates from original flight path. The radar system includes an antenna network capable of being controlled to point in required direction. The system will operate at relatively low altitude.

Title: Method for synchronising film and sound recordings - uses zero reset chronometers controlling synchronising signal images
IPC: G03B31/04
Filed: 1974-03-29
Abstract: Associated with the sound and image recorders are independent or non-independent chronometric devices having zero reset and lapsed time display means. The chronometers are simultaneously reset to zero before the commencement of filming. An indication representing the time displayed by the associated chronometer is recorded photographically on the film of the image recorder. This is done each time the image recorder is started or stopped. A signal indicating the time displayed by the associated chronometer is recorded on the magnetic tape of the sound recorder each time the recorder is started or stopped. The indications and optical signal and/or sound signals thus recorded are identified and synchronised at the time of operation of the system.

Title: Tensioning by passing through adjustable roller pair - which are rotated by yarn, one roller being covered with elastic material (BR170876)
IPC: B65H59/16
Filed: 1974-12-24
Abstract: Yarn is tensioned by being passed through the nip of a pair of rollers, the surface of one of which is covered with an elastic matl. The sepn. of the rollers is adjustable to regulate the pressure exerted on the yarn as it passes through the nip and the yarn is so guided through the nip (e.g. by guides upstream and downstream of the nip) that the action of the yarn on the rollers rotates them. The tensioning device is used in e.g., spinning frames, horns, etc. Rotation of the rollers exerts a braking force on the yarn and so tensioning it. The device doesn't wear out as quickly as e.g. devices in which the yarn passes between a pair of discs biassed together. The braking force applied to the yarn is adjustable.
