Title: Automatic load distributor for three-axle vehicle - has pneumatic pressure applied only to suspension for drive wheels of second axle
IPC: B60G17/033
Filed: 1974-07-12
Abstract: The pneumatic pressure applied to the suspension for the drive wheels of the second wheel axle is proportional to the load transported by the vehicle up to a predetermined max. load. On exceeding this load, the two pneumatic suspensions of the second and third axles are subjected to different pneumatic pressures, so that the pressure in the suspension of the drive wheels is constant and is proportional to the max. load while the pressure in the suspension of the third wheel axle is adapted to be proportional to the load which exceeds the max. load. In this way the load on the drive wheels is controlled to ensure their max. effectiveness to power the vehicle.

Title: Heat pump operating with the evaporator in air - and fitted with an additional defrosting evaporator
IPC: F25B29/00
Filed: 1974-09-13
Abstract: The heat pump takes heat from atmospheric air through the evaporator (3) which is finned to augment its effective surface. At low temperatures and high humidity conditions the evaporator freezes over and becomes inefficient. Hence an auxiliary evaporator (10) is placed in series with the other in order to preheat the air passing over it. This disposes of the freezing conditions over the fins of the main evaporator. The auxiliary evaporator is only brought into use when necessary and thaws out of its own accord when not in use. The efficiency of the heat pump is maintained under all conditions.

Title: Smoke bomb comprising smoke generating liquid and explosive charge - giving instant smoke prodn. and wide area dispersal
Inventor: CARRE PAUL
IPC: F42B30/04
Filed: 1975-04-18
Abstract: Smoke- producing charge, for a smoke shell or bomb, uses a non-burning smoke generating liquid esp.

Title: Granular highway surfacing carpet with low binder content - relies on particle interlocking under compaction for stability
IPC: E01C7/18
Filed: 1975-06-13
Abstract: The low binder content granular carpet for surfacing highways, obviates low temperature brittleness and high temperature deformation, and has crushed rock with a grading curve falling with a narrow zone and a hydrocarbon binder as constituents. The proportion of binder is such that inter-particle cohesion is obtained solely via the interlocking of the granular particles under compaction and traffic. For richness modules of 2.8 to 3.5 binder quantities are from 5 to 7% of aggregate weight. The binder is of low viscosity and is added hot in sufficient quantity to cover granules with a film without inhibiting particle interlocking under compaction, aggregate size also being dictated by this requirement.

Title: Forestry fire fighting method - distributes solid or liquid nitrogen by air or on ground forming oxygen excluding layer
IPC: A62C3/02
Filed: 1975-06-23
Abstract: The seat of the fire in the forest or plantation is surveyed from the air by helicopter and the hottest areas identified. Solid or liquid nitrogen, kept in insulated containers is dropped and distributed over the area. The nitrogen becomes gaseous and reduces the temperature of the fire. The nitrogenous gas blanket prevents oxygen from reaching the flames and these are stifled. The surrounding temperature is cooled, with the formation of frozen carbon dioxide taken from the air. The nitrogen can also be distributed at ground level and the burnt-out area is not damaged by chemicals to prevent replanting.

Title: Forming endless metal printing band - by photogravure, heating and welding strip before finishing
IPC: B41J1/20
Filed: 1975-07-18
Abstract: The parent metal is a martensitic stainless steel, vacuum melted and 0.4 mm thick. this is cut into a strip equal to the developed length of the band, plus longitudinal and end allowances.

The strip areas which are not photogravure are then apertured with reference marks and the strip trimmed, demagnetised and degreased and the two ends thinned down, brought together and electron beam welded in a vacuum chamber. The faces of the characters are finally chrome plated, or given a layer of titanium carbide, to improve wear resistance.

Title: Antiviral ionic complex of linear polyarginine - and natural double-chain ribonucleic acid or its derivative
IPC: A61K31/785
Filed: 1975-10-22
Abstract: Antiviral substance comprises a mainly ionic complex in which the cationic part is a linear polyarginine having at least 5 arginine units and the anionic part is (a) a double chain ribonucleic acid polyanion, the double chain ribonucleic acid being of natural origin or (b) a polyanion of a double chain deriv. of a natural double chain ribonucleic acid.

Title: DC coupling for A.C. systems of dissimilar frequency - is fitted with DC poles connected to earth through RC circuits
IPC: H02M7/757
Filed: 1975-12-10
Abstract: The object is to minimise the risk of heavy fault currents and high voltage peaks on the power components in a circuit coupling two a.c. power systems of dissimilar frequency. Rectifier (5) and inverter (6) are in a d.c. loop (7) and are connected to their respective a.c. systems (1, 2) through appropriate rectifier transformers (3, 4). The poles of the d.c. circuit are indirectly connected to earth (9) through RC elements (10), typically arranged symmetrically with respect to the poles. As there is no direct earth connection a single breakdown in insulation does not give rise to heavy fault currents, and the RC elements also act as voltage surge suppressors. The chances of a double earth fault on opposite poles is considered so extremely remote that it can be ignored.
