Title: Hydrocarbon fuels contg. water or hydrogen peroxide - and a sulphonated fatty material
IPC: C10L1/32
Filed: 1974-02-22
Abstract: Modified hydrocarbon fuels contain (a) sulphonated fatty materials (mineral, vegetable or animal) and (b) H2O or H2O2. The fuels can contain up to 15% H2O or H2O2 and up to 15% sulphonate, opt. together with a protective lubricant. They can be prepd. by simple mixing. The incorporation of H2O or H2O2 in motor fuels allows savings to be made in gasoline consumption while increasing combustion efficiency (increased r.p.m. or m.p.g.), reducing CO emission, and giving good cold-start performance and smooth running, without requiring any modifications to fuel-supply system or engine design.

Abstract: A tyre comprising a carcass and tread band is so proportioned that the strip of the carcass underlying the tread band possesses a stiffness per unit width per unit load per unit width, as defined by the expression Ed/W, where E is the compression modulus, d the thickness of the strip underlying the tread band and W the max. load per unit width of tread, is not smaller than a value made up from the parameters d, W, the radius, R, the depth of side wall k, the tread width b, and wheel rim radius H, and the tensile modulus Y of the side wall and a value t equal to twice the mean thickness of side wall. Pref. this stiffness value does not exceed A(1+kbdE/HRtY), where A is 700 (500). With the stiffness and defined above, the tyre does not bulge or collapse with loss of internal pressure down to atmospheric pressure. The purpose of the upper limiting value is to prevent excessive stiffness and hard running. The tyre may be cord-reinforced rubber. The modular ratio between the strip beneath the tread and the side wall material is from 1/10 to 5/1.

Title: Heat exchanger for military aircraft - has series of baffles to prevent escape of liquid and encourage droplet deposition
IPC: B64D13/08
Filed: 1975-05-20
Abstract: The heat exchanger (1) has header plates (2, 3) supporting tubes (4). The heat exchanger is kept full of water through a pipe (8) from the tank 10). This water cools the air flowing from the inlet (5) through the tubes (4) to the outlet (6). Any vapour formed from the heated water rises up the pipe (11) and flows through an opening (16) into the upper part (A) of the tank (10). The upper part of the tank (A) contains a series of baffles (17, 17a, 17b) which encourage deposition of any liquid droplets intrained in the water vapour. A relief valve (23) allows the water vapour to escape if the pressure rises above that of the atmosphere. This is particularly applicable to military aircraft performing high speed manoeuvres.

IPC: H01L21/225
Filed: 1976-02-12
Abstract: Process for mfg. an aluminium-doped insulation layer, where a silicon substrate (1) is provided with an epitaxial Si layer (2) followed by a layer (3) of SiO3; after producing windows by photo-masking, boron is vapour deposited to make the base, and Al to obtain the insulation; a second photo-mask is then employed for selective etching of the Al to have Al in the insulation windows. The novelty is that the insulation diffusion of Al, and the base diffusion of boron are undertaken simultaneously at 1180-1230 degrees C. in a non-reducing or an oxidising protective gas atmos. The gas atmos. pref. consists of N2 followed by oxygen, and the second mask pref. results in a gap between the residual Al and the SiO2 (3).
