Personal history

This photograph shows H Kent-Norris with his team of Newbury Diesel Company spotters during WW2. He is the tall fellow in the middle but the names of the rest of the crew are lost in the mists of time. If you know any names, they would be appreciated.
This photograph is courtesy of Darrin Pearce.
His father, Reg Pearce worked in the drawing office from 1942 to 1980. Reg's wife also worked in the drawing office at the Diesel Company.

a recently discovered photograph of an engine on test. The person with the blueprint is of course Kent-Norris and the person on the control handle is a young Edgar Wildsmith, the NDC commisioning engineer. Have to presume that the man in the bowler is an Everard inspector.

H Kent-Norris registered several patents during his time at Newbury Diesel Company.
This patent taken out in 1920 was for an injection system for a hot bulb engine.

GB130742 is referenced by 2 patents.

130,742. Norris, H. Kent-. Aug. 2, 1918. Cylinders receiving liquid fuel. - Heavy liquid fuel from a pump j is injected first through a nozzle g in a preliminary combustion chamber c and then through a main fuel-injection nozzle in the head of the cylinder, the second injection being prolonged for maintaining combustion at constant pressure. The chamber c contains a hot-plate 7 which may be heated. at starting, by a lamp. During the early portion of the delivery stroke of the pump j, the fuel for the first injection escapes past a valve r carried by the stem of the needle valve q, and traverses a passage t leading to the injector g, the orifice of which is provided with a spring-controlled ball valve w. When the valve r is closed by the pressure of the fuel behind it, the main injection takes place through the orifice in the nozzle d.; The needle valve q is held in its closed position by a spring y, the tension of which is adjustable. According to a modified construction, the beat valve is dispensed with, the passage t being cut off by the sliding action of the spindle of the needle valve. Instead of entering a separate chamber, the igniting-charge may be admitted to the main combustion chamber.


A later 1934 patent which related to blowers and scavenging in Sirron engines.
