Title: Vehicle collision avoidance device - with flat plate inclined grid polariser is used as a passive reflector
IPC: G01S13/75
Filed: 1974-01-07
Abstract: A source of radiation and a detector is in a vehicle. Reflectors on other vehicles provide return echoes of a different polarisation than that which they receive. PArallel strip polarisers are used as the reflectors, which suppress radiation in one plane, converting it to polarisation in a plane perpendicular to this. The transmitter and receiver antennae are placed next to each other and transmit parallel beams. The reflector comprises a metal reflecting sheet over which parallel wires are placed, spaced away and insulated from it so that the incident radiaton undergoes a phase shift of 90 degrees. The grid is at 45 degrees to the transmitted polarisation plane, and is insulated from the reflector using a low-loss dielectric.

Title: Self-adhesive photographic paper - has thermally activated adhesive on rear side, inert to photoprocesses
IPC: G03C11/14
Filed: 1974-12-18
Abstract: The rear surface of the photographic paper is provided with a special coating before the emulsion is added to the front. This coating is resistant to the normal processing chemicals and conditions, and is insoluble in water.
