IPC: A61K35/14
Filed: 1984-08-17
Abstract: The invention relates to a cancer-inhibiting animal blood and animal bone marrow which can be transfused into humans, to a method and to an apparatus in which, by trituration in a physiological solution rich in <37>Cl and in argon, krypton, xenon, and radon gases, the blood and marrow are purged of their heat-melting light components, H<+>, light isotopes, light gases and water vapour, which are implicated in incompatibility and immunodeficiency as a result of their increased concentration. The apparatus is composed of a vessel 1, a tap 2 for introducing heavy inert gases, a lid 3, a whisking mixer 4 which, by swirling and whisking, breaks the blood and marrow dissolved in physiological solution down to colloidal dimensions, thereby purging them of their excess of light substances, and a tap 5 for discharging these substances released on trituration. The apparatus according to the invention is intended for the preparation of cancer-inhibiting blood and animal bone marrow which can be transfused universally into humans.

Title: Types of and methods for constructing buried rooms for preserving foodstuffs, for storing and safeguarding goods and for sedentary and leisure activities
IPC: E04B1/00
Filed: 1984-12-10
Abstract: The invention relates to a type of buried room having a substantially regular polygon shape, comprising protuberances in the form of cells or chimneys on its lateral peripheral faces. The chimneys are intended to be equipped with shelves suitable for the storage of cylindrical objects. The polygon may be extended by inserting faces parallel to a central axis, comprising the same protuberances. The shell is monolithic with a concrete base slab and a concrete roof slab. Access is, in principle, from above, via a trapdoor and a staircase. This building method does not comprise, in principle, any cases used as structure. It uses a mould which is dismantleable or which is used as an internal wall acting as formwork for the lateral reinforced-concrete frame up against the peripheral face of the hole. The formwork could be replaced by prefabricated elements, members made of concrete or ceramics, used for the same purpose as formwork for the wall and for the frame.
