Title: Anti-collision system for tracked cranes - has extensible cable stretched between cranes with switch to cut power if cable slackens
IPC: B66C15/04
Filed: 1976-04-29
Abstract: The system automatically prevents any collision between cranes travelling on the same tracks. It uses an extensible cable stretched between the cranes, a switched cutting the power if the cable slackens due to cranes approaching too near each other. One set of bogies of each crane, on the same side of the track, has a vertical arm (6, 7) each end. These hold a pair of rollers (15, 16) one end being higher. The cable (8) passes between these and is counter-weighted for tensioning. A switch (17, 18) on each arm normally contacts the cable and if this latter slackens, the contact (18) drops to interrupt the supply.

Title: Tyre deflation warning device on vehicles - uses radio transmitter built into valve which actuates receiver and warning at given low pressure
Inventor: MAY FRANK HERBERT
IPC: B60C23/04
Filed: 1976-05-14
Abstract: A warning device gives notice of type deflation on a vehicle. It consists of a radio signal generator in the tyre valve body. When the pressure drops to a chosen value a signal is transmitted to a receiver which is mounted on the vehicle body. The receiver actuates a warning signal. The transmitter can be started by closing contacts, actuated by pressure drop. It has an aerial which is a metal buckle, buried in the rubber of the tyre itself. The transmitter has a permanent magnet and a coil or rod and the spacing of the magnet poles is varied by the tyre pressure. The transmitter power is given by batteries, renewable or rechargeable. Alternatively, the vehicle battery can be used. A method of brake application can be incorporated if the driver ignores the signal.
