Patent GB-2212915-A (GB)
Title: Agrochemical screening
Inventor: KAETHNER TIMOTHY MARK
IPC: C12Q1/02
Filed: 1987-12-01
Abstract: Potential agrochemicals are tested by exposure to an in vitro biological culture capable of producing a detectable indicator material in response to a change in the metabolism of the biological culture; and monitoring the culture to determine whether the indicator material is produced. The method is based on the effect on the metabolism of biological cultures of potential agrochemicals being tested. Typically, detectable effects would be the production of detectable secondary metabolites in place of culture growth but may include death of cultures due to fatal interference with metabolism. The culture is e.g. an algal, a plant cell suspension or plant tissue culture. Carotenogenic species, which are normally green but produce yellow, orange or red secondary metabolites in certain circumstances and turn white on death are particularly preferred: these include algae such as Dunaliella species.

Title: Generating and utilising electric discharge entities
Inventor: SHOULDERS KENNETH R
IPC: H01J3/00
Filed: 1988-05-09
Abstract: Disclosed are many different arrangements in which, in a vacuum of gas-filled enclosure by pulsing a cathode with respect to an anode or counter electrode, there is generated from the discharge therebetween high electrical charge density entities, called EV's in the space patton which comprise discrete, self-contained, negatively charged bundles of electrons. In the channel cource 900 shown, Figs 62 and 63, for generating EV's a ceramic base 901 has a guide channel 903 therein in which cathode 902 is located and successive dynodes 905 are provided underlying the channel 903 with a counter electrode 906 on the opposite side of the base to the channel. Cathode 902 may be replaced with a photon source and a distributed resistor 904 may underlie the channel. In operation, the charge density provided by the initial electron source is multiplied by the successive dynodes, eg with gains of 10<6>, until it reaches the critical level for forming an EV. The EV, once formed, is constrained to follow the channel guide. The dynodes may comprise metal covered with a thin dielectric layer such as Al2O3 doped with W or Mo. Many different devices utilizing the EV's so generated are disclosed. For example, fig 67 shows an RF generator comprising a guide channel 993 in a dielectric base of serpentine form such that an EV introduced at 991 at constant velocity and constrained to follow the guide emits RF radiation whose duration, frequency and harmonic content is controlled by the shape of the guide. A circulator for RF energy, Figs 65 and 66 (not shown), which can store the RF energy generated, is also disclosed. Other devices disclosed which utilise the EV'S includes flat panel displays, deflection switches, charge storage on memory devices, stepping registers and anologue to digital encoders. <IMAGE>

Abstract: The controller generates a cyclically varying lamp drive current corresponding to the combination of a first, smoothly fluctuating, signal of a relatively low frequency and a second, sharply fluctuating, signal of a high frequency relative to the first signal thereby to produce a flickering flame effect. The first signal may be produced by a low frequency sinusoidal oscillator 2 having a period of 20 to 40 seconds. The second signal may be produced by a generator 3 as a noise signal having a bandwidth of 0 to 16 Hz. The drive signal may be produced as the weighted sum of these signals and an intensity control signal. The signals may alternatively be produced by digital signal processors. The drive signal may be provided as a pulse width modulation signal (Fig. 8). A decoration set may incorporate a plurality of independently operating controllers (Fig. 10). Lamps for use in the system may have a frosted glass diffusor (8), (Fig. 9), shapes like a candle flame and enclosing an upper filament (19) energised by the controller and a lower filament (21) operating at below full brightness on a constant amplitude drive current. Alternatively, an axial filament (33), (Figs 11 to 13), energised by the controller may be partially surrounded at its base end by a V-shaped, transversely extending filament (27) energised by the constant amplitude currents. <IMAGE>
