Title: Fuel tank for LPG powered vehicle - with self cooling through gas expansion and with cooling loop
Inventor: BEDFORD TIMOTHY JAMES
IPC: F17C9/02
Filed: 1975-06-24
Abstract: The fuel tank for the (LPG) powered vehicle is heat insulated to keep the fuel below the triple point. If the fuel requires cooling then the engine automatically draws gas from the top of the tank, so that with adiabatic expansion of fuel in the tank a self cooling effect is achieved. If the tank requires extra cooling then fuel is taken out through a heat exchanger and recompressed and cooled. Heating coils under the tank vapourise the fuel if adiabatic expansion produces insufficient fuel. If the fuel is cool enough then it can be taken from the tank in liquid form and expanded into gas through an external heat exchanger.

Title: Automatic detection of knots in wood - is by use of array of reflected light beams from sawn wood surface
Inventor: MATTHEWS PETER CHARLES
IPC: G01N21/898
Filed: 1975-07-30
Abstract: The equipment is for automatically detecting knots, rot, and other faults in sawn wood which passes under an array of inspection heads. The operation of the equipment depends on the light reflecting properties of sawn wood, which is composed mainly of tracheid cells lying along the grain of the wood. A light beam is reflected considerably more efficiently across the grain than along it. The basic detector consists of a light source (2) which directs a beam of light on to the surface of the wood (1) so that a photo detector (4) is illuminated by the reflected beam. A wall (3) prevents direct illumination and a threshold detection circuit (5) fed by the photodiode is used to detect when the reflected light, and so the grain direction, has changed. An array of such elements is mounted across the wood surface to be inspected, and the surface is then passed beneath it.
