Patent ZA-792668-B (ZA)
Title: Energy conversion method and system
Inventor: EGOSI D
IPC: F22B3/00
Filed: 1979-05-29
Abstract: A mechanical energy conversion method and system for the restoration of dissipated heat energy, contained in natural or artificial water bodies at or near ambient temperatures, to industrial process heat, mainly in the form of steam up to 200 DEG -400 DEG  C. The sensible heat contained in a water body is concentrated as latent heat in low pressure water vapor which is thermo-compressed by steam ejection to an intermediate pressure level, wherefrom mechanical compression takes over, generating highly superheated output steam. The ejecting steam is not generated in a boiler, but is continuously regenerated by the compressor and routed back for repeated ejection. The compressor is driven by a heat engine whose reject heat is collected and upgraded as well. The output of heat energy is essentially equal to the sum of the heating value of the fuel consumed and the intake of latent heat and amounts thus to substantially more than the heating value of the fuel alone.

Title: Method of making diamond compacts for rock drilling
Inventor: BOVENKERK H
IPC: E21B10/567
Filed: 1980-10-09
Abstract: An improvement in the manufacture of diamond compacts is disclosed in which a cylindrical mass of polycrystalline diamond is surrounded by and bonded to an outer mass of metal which provides support for the diamond. The improvement comprises the use of seed diamond to grow the polycrystalline mass under high pressure-high temperature (HP/HT) conditions from non-diamond carbon, utilizing a catalyst metal contained in the outer metal annulus. Preferably, this improved process is carried out using a cup-shaped metal mass having a stable carbide content of at least 10% and a coefficient of thermal expansion slightly higher than diamond. It is also preferred to heat the sample (the outer metal mass and the inner graphite mass) directly by passing an electric current through the outer metal mass in the HP/HT process during which the polycrystalline compact is formed.

Patent ZA-846599-B (ZA)
Title: Activated electrodes based on ni,co,fe with active coating
Inventor: DIVISEK JIRI DR
IPC: C25B11/06
Filed: 1984-08-24
Abstract: A process for the manufacture of thin activated electrodes including a base metal, which can be iron, cobalt or nickel, with a good adhering active surface layer. Both the base metal and the surface layer are galvanically sequentially deposited as separate layers on a removable electrically-conductive carrier. The surface layer is deposited as an activatable alloy including the base metal and a leachable metal, particularly zinc. The galvanizing deposited layers are subsequently separated as a unit from the carrier. The alloy is activated by leaching the leachable metal therefrom before, during or after separation of the carrier. Two activatable layers of alloy can be deposited on the carrier with a layer of the base metal deposited between the alloy layers.
Patent ZA-863014-B (ZA)
Title: Cultivation of morchella
Inventor: OWER RONALD DEAN
IPC: C12N1/14
Filed: 1986-04-22
Abstract: The invention pertains to culturing ascocarps or fruitbodies of species of the genus Morchella. Mycelia are provided nutrients and subsequently produce sclerotia. Sclerotia store sufficient nutrient to supply the ascocarps that are developed later. The mycelia and attendant sclerotia are established in a nutrient poor substratum. The fungus is induced to give rise to ascocarp development by initially maintaining the fungus in an environment that is poor in exogenous nutrients, and by exposing the fungus to a high level of water. After induction, primordia appear. The period from primordia appearance until midway to maturation of the fruitbodies represents a critical period during which the fruitbodies are prone to abort. During this critical period, particular attention is directed to maintaining favorable conditions. The fruitbodies, which may be grown to maturation, are harvested.

Title: Optically active compounds
Inventor: WOOD HAMISH CHRISTOPHER SWAN
IPC: A61K31/505
Filed: 1987-09-02
Abstract: The present invention relates to the preparation of substantially pure diastereoisomers of derivatives of tetrahydrofolate and the use of such diastereoisomers. More particularly the present invention provides a process for the preparation of a desired substantially pure (6R or 6S) diastereoisomer of a derivative of tetrahydrofolic acid or salt or ester. The process comprises the steps of: attaching a chiral auxiliary group at either N-5 or N-10 of a mixture of 6R and 6S diastereoisomers of tetrahydrofolic acid, separating the new diastereoisomers, recovering the desired new diastereoisomer (6R or 6S) corresponding to the desired (6R or 6S) diastereoisomer, and converting the substantially pure new diastereoisomer recovered into the corresponding diastereoisomer.
