Abstract: A television picture transmission system using conditional replenishment employs a scanning rate at the transmitter which differs (for asynchronous operation, slightly; or for operation between systems using different standards, considerably) from the scanning standard at the the receiver. The frame rate conversion is effected by the updating loops at the transmitter or receiver by, respectively, periodically stopping the coding loop for a field or frame so that no data is produced to produce a lower frame rate or periodically repeating a field or frame in the loop without adding any updating data so as to produce a higher frame rate. Resulting variations in data rate are accommodated by utilising the buffering inherent in conditional replenishment systems. The jerkiness of motion in the received picture resulting from stopping the loop or repeating a field or frame can be reduced by the use of temporal interpolation in the generation of the updating data to anticipate the stopping or repeating of a field or frame, whilst conversion of the number of lines per frame can be effected by spatial interpolation using a transversal filter.

Abstract: A battery charger comprises a power supply 6 for supplying current pulses to a battery 71 to be charged. A microprocessor 3 receives from an analog-to-digital converter 20 codes representing the voltage between the battery terminals with the battery off-load between charging pulses and monitors the ratio of the voltage difference (V<sub>3</sub>-V<sub>5</sub>) during a first period following a charging pulse to the voltage difference (V<sub>10</sub>-V<sub>12</sub>) over a second period following the charging pulse, with the second period ending after the beginning of the first period. The value of this ratio reaches a peak value and then declines, and the microprocessor determines when the value of the ratio falls below a peak value thereof by a predetermined amount to terminate fast charging of the battery, after which the battery may be removed or may remain on a trickle charge. An accurate, reliable, and consistent determination of completion of charging of sealed nickel-cadmium batteries is thus provided.

Abstract: A fast low angle shot ("FLASH") NMR method is described, which uses radio frequency excitation pulses having a flip angle substantially less than 90 degrees, and subsequent reading gradient reversal for producing a gradient echo signal. The small flip angle pulses create an equilibrium state between longitudinal and transverse magnetization, which allows to apply the radio frequency pulses repeatedly with high repetition rate to produce gradient echo signals of essentially equal strength, without any intervening delay for magnetization restoration or recovery.

Abstract: The invention belongs to the areas energy technology and methods for transformation of the energy of permanent magnets (from the rotation of the electrones around the parallel atom axises of the permanent magnets) to mechanic energy. The method solves the technical problems to create screen of active type, which can screen magnetic fields, at the samt time screen which does not itself be acctracted or repelled by magnetic field. Other materials screening magnetic fields without themselves being attracted or repelled by the magnetic field do not exist. Iron for example screens the magnetic field but is itself attracted by the magnetic field and in order to pull the iron from the magnet is energy using needed. Martin Denev's method is solving this problem by building permanent magnet structures similar to the chromosomes and nervous system in living organisms, since living organisms have built structures that can both screen magnetic field and the living system is not attracted or repelled by outer magnetic field, even in case of that iron is included in the living system. Only such a chromosome-like permanent magnet structure can build a screen under which protection one can situate against each other two same poles of permanent magnets, which after taking away of the screen can perform work. This cycle can be repeated as much as wanted, in a motor,which transforms the magnetic energy to mechanic. This is no perpetum mobile, since the magnetic energy has its origin in the permanently rotating electrones, and the energy is all the time supplied in the system. In perpetum mobile machines no energy is supplied all the time during the work.
