Title: Waveform expansion by sampling
IPC: G01R13/34
Filed: 1970-07-06
Abstract: 1334523 Sampling periodic waveforms SOLARTRON ELECTRONIC GROUP Ltd 2 July 1971 [6 July 1970] 32685/70 Heading H4T In an arrangement for expanding the time scale of a periodic signal by sampling the latter at instants determined by amplitude coincidence of successive cycles of a ramp waveform synchronized by the periodic signal with successive levels of a staircase waveform, the latter being reset when a predetermined maximum level has been reached and the cycle of operations, which determines the period of the expanded waveform, then recommencing, the sign of any discontinuity between the samples taken just before and just after the reset instant is sensed and employed to adjust the slope of the ramp in the sense which reduces the discontinuity. As shown in Figs. 1 and 2, comparator 26 produces pulses controlling sampler 28 (to which the waveform 10 to be sampled is supplied) at instants A, B, C, D on coincidence between the amplitude of a ramp waveform 13 from generator 23 (triggered by a signal derived from waveform 10) and the level of a staircase waveform 14 from generator 25 to produce on output line 31, a lower frequency replica 11 of period P which has a discontinuity 15 at the position 17 where the second cycle should commence. The latter is initiated when staircase generator 25 is reset via delay circuit 35 from trigger 33 and in the operation of the present invention the output of 33 is utilized via delay circuit 41 and switch 36 to sample the waveform 11 (before the staircase generator is reset) and supply such sample via an integrating amplifier 37 as an off-set voltage to the comparator 26 (in effect, adding it to the staircase waveform) so that the first sample of the second cycle is taken at an instant which is displaced from the beginning of the ramp proportionally to the level of the last sample of the preceding cycle. Shortly after the staircase generator has been reset the output of trigger generator 33 operates switch 40 to supply the output of a predictor 38 (e.g. a high-pass filter) to anintegrating amplifier 39 the output of which controls the slope of the ramp generator 23.

Title: Battery charging systems for road vehicles
IPC: H02J7/14
Filed: 1971-05-17
Abstract: 1340063 Automatic voltage control JOSEPH LUCAS (INDUSTRIES) Ltd 17 May 1971 [13 June 1970] 28745/70 Heading G3R In a battery charging system for a road vehicle of the type comprising a three phase permanent magnet alternator 11 charging a battery 14 through a full wave rectifier including thyristors whose gate current is controlled by a voltage regulator, the risk of damage arising when the battery becomes disconnected is minimized by constituting the rectifier in the form of four thyristors 4, 5, 6, 7 associated with two phases of the alternator and two diodes 8, 9 associated with the remaining phase, means being provided for sensing the voltage surge caused by disconnection of the battery and ensuring that the gate current is removed from the thyristors for sufficiently long to ensure that the thyristors turn off. In normal operation variation of the rectifier output voltage above or below a predetermined value causes a Zener diode 19 to be repectively conductive or non- conductive, a transistor 21 to be respectively conductive or non-conductive and an oscillator supplying gate current to the thyristors to be respectively non-operational or operational. The oscillator comprises a transistor 26, diodes 25, 32 resistors 28, 33 and a transformer having a primary winding 27 and secondary windings 31, 35---38 of which the last four supply respective gates of the thyristors 4---7 through diodes 46 ---49. During the part of the oscillator cycle when transistors 26 is non-conducting, transistor 21 is turned on by current through resistors 23, 24 the voltage on the winding 27 reverses and the current decays in members 31, 32, 33. If the battery becomes disconnected, the rise in voltage of the rectifier is sufficient to make conductive a normally non-conductive Zener diode 42, thus causing charging of a capacitor 43, turn-on of the transistor 21 and turn-off of the oscillator. Subsequently the transistor 21 is held in the conductive condition by discharge of the capacitor 43, the delay being such that the oscillator is non-operational until the thyristors 4---7 have turned off. To limit the amplitude of the surge produced by disconnection of the battery, a Zener diode may be connected across the output of the rectifier or the diodes 8, 9 may take the form of Zener diodes which normally operate as ordinary diodes.

Date May 22, 1998A method for the identification of genes that are essential for the maintenance of specific cell phenotypes is disclosed. The method includes the initial step of identifying a cell type with a phenotype of interest. Gene inactivation is performed on an aliquot of cells of the cell type of interest. Positive selection is then performed to an aliquot of the cell culture to which gene inactivation has been applied. Cells which continue to maintain the phenotype following gene inactivation have not had the gene of interest inactivated whereas cells in which genes necessary for maintaining the phenotype have been inactivated have been lost. Utilizing subtraction analysis between treated and untreated aliquots the gene in the cells which has been inactivated that affects the phenotype of interest is identified. Genes that are identified by the method are also disclosed as well as antibodies directed against the gene product of the identified genes. Further a customized kit for the practice of the gene identification method is also disclosed.
