Title: Wood-plastics composite prodn - by polymn of org cpd impregnated in wood coated with catalyst-contg inert layer
IPC: B27K3/18
Filed: 1974-03-27
Abstract: Wood and plastics composites are prepd. by impregnating wood with polymerisable org. liqs. (I), coating the impregnated wood with a protective inert liq. contg. a polymsn. catalyst for (I), solidifying the liq. coating, effecting polymsn. of (I), and removing the coating by heating. Incorporation of the catalyst into the protective coating obviates prior art drawbacks regarding recycling of the catalyst-cont. excess monomer from the impregnation step, which caused storage problems. In the above process the free radicals are formed inside the inert coating and diffuse into the impregnated wood. The process can also be carried out in open air in an oven, or using a heating press., or in hot water.

Title: Machine deriving energy from water pressure - has wheels driven by belts carrying weights and air bags
IPC: F03B17/02
Filed: 1974-06-06
Abstract: The machine has two wheels mounted on parallel shafts one above the other and immersed in a vessel full of water.

Title: Internally assisted electro control valve - double valve type acting on differential pressure for cryogenic installations
IPC: F16K31/40
Filed: 1974-06-20
Abstract: A valve body (1) with screwed holes (2) (3) and a valve seat (5), has a moving element (6) which slides in a brass guide (7). A coil (13) is energised when required and moves this element against a spring (11) which normally closes the valve (20). There is another return spring (23). When closed, the valve (28) seats on its seat (26) and blocks flow between the screwed holes (2) (3). When opened by the coil (13) the moving element (6) moves up (8), overcoming the spring (11). The opening of a pipe (25) gives a sudden pressure shock in the upper chamber. The valves (20) is thus subjected to differential pressure to open it.

Title: Electrical generator avoiding atmospheric pollution - uses inductive forces between adjacent hollow ring ion accelerators
IPC: H02K53/00
Filed: 1974-09-23
Abstract: The electronic electrical generator comprises two glass hollow evacuated rings into one of which is introduced positive ions, e.g. hydrogen ions, or protons and into the other negative ions e.g. oxygen or electrons, the particles being accelerated by one or more tubular high tension anodes, positive when the ions or particles are negative and negative when they are positive, while the role of the cathode is secondary and it need not be heated to emit ions or particles, whereby the necessary accelerating power is very low.
