Title: Releasing poly-hydroxy:carboxylic acid granules from bacteria - by inducing lytic gene at high ionic strength then re-suspending cells to cause spontaneous lysis
Inventor: LUBITZ WERNER PROF DR
IPC: C12N9/14
Filed: 1990-02-08
Abstract: Releasing poly-3-hydroxycarboxylic acid (I) granules from Gram negative bacterial cells contg. them, is effected by expression of a cloned natural or chimaeric lylic gene, the new feature is that before inducing the gene the ionic strength of divalent cations is increased to 0.05-0.5M. The expression of the gene is induced by increasing the temp., the cells harvested and, while still wet, resuspended in water or buffer soln., so that release of the granules occurs as a result of spontaneous lysis.  Lytic gene is pref. cloned gene E from the phage phi X174. USE/ADVANTAGE - Treatment produces large openings in the cells, allowing complete sepn. of the granules while lipid remains in the cells.

Title: Transmission of solar energy over extremely large distances - using laser beams to convey energy via reflectors on geostationary satellite
Inventor: BROSOW JOERGEN
IPC: H02J17/00
Filed: 1990-10-31
Abstract: At the transmission station, electrical energy is created in a solar chimney (2) where the updraught of air heated by solar radiation drives a wind generator located inside it. The electrical energy is converted into laser radiation (3) and beamed to reflectors (6,6') on a geostationary satellite (5). The laser beams (4,4') are refelected to concave mirrors at the receiving stations (7,7'). The radiation is converted to heat using a Stirling engine, for example, from which electricity can be generated. The frequency of the radiation is chosen for minimum absorption loss in the atmosphere and the two beams are transmitted as pulses so that the off-period of one beam coincides with the on-period of the other beam. Several laser transmitters can work cyclically at the station (3). Control beams of lower strength can be used by both sending and receiving stations to monitor and reset the reflectors. To minimise the atmospheric path length, and hence absorption, when using a single satellite, two or more satellites vertically above the stations (1, 7, 7') can be used, with transmission between these satellites parallel to the earth's surface. USE/ADVANTAGE - Transmission of solar-drived energy over extremely large distances from desert areas to areas deficient in solar energy. Cheaper and safer than alternative method using transport of liquid hydrogen; reflectors controllable so that different receiving stations can be supplied from different sending stations.
