Title: Extraction of plant material by using carbon dioxide
Inventor: EVANS BRIAN ROY
IPC: B01D11/02
Filed: 1983-04-19
Abstract: Plant material (for example, milled hop pellets) is placed in a pressure vessel and carbon dioxide is passed through the vessel in order to extract essential oil and resin components. Said passage is stopped after a predetermined period of time and inert gas(es) is/are used to displace said carbon dioxide and the extract(s) from said vessel to another location. If liquid carbon dioxide is used, it is displaced to an evaporator in which the extract is deposited, carbon dioxide being gasified. If supercritical carbon dioxide is used, it is displaced to a separator.   Alternatively, the plant material may be steeped in liquid carbon dioxide which, after the steeping period, is displaced as aforesaid. The gases (carbon dioxide and inert) may be vented to atmosphere or recovered for re-use. Extraction using liquid carbon dioxide is isobaric whereas using supercritical carbon dioxide, the pressure in the pressure vessel is higher than in the separator.

Patent GB-2140592-A (GB)
Title: Memory unit comprising a memory and a protection unit
Inventor: KAPLINSKY CECIL HERTS
IPC: G06F21/14
Filed: 1984-04-26
Abstract: A memory unit in which preselected program words stored in some of the memory locations are modified before transmission to the output pins of the memory unit, in order to protect those program words against illegal copying. When a jump instruction is decoded, the decoder issues a command to a random number generator 19, to an adder 25 and to a subtractor 26. The adder adds the random number output by the generator to the destination address of the pump instruction to form a pseudo-jump address which is sent to the processor 14. When the processor subsequently addresses the memory 12 to acquire the program word, the pseudo-jump address is converted to the original destination address by the subtractor. Copying pseudo-addresses results in the copied program being useless.   Address tables may be used instead of the random number generator, adder and substractor. <IMAGE>
