Abstract: 1,190,109. Feeding sensitivity discs. BECTON, DICKINSON & CO. 29 Nov., 1967 [16 Feb., 1967], No. 14243/68. Divided out of 1,190,108. Heading B8S. [Also in Division C6] Sensitivity discs used in the laboratory study of microbiological cultures, growths and specimens, are ejected simultaneously from a battery of some 8 or 12 cartridges 48, Figs. 3 and 4, by the manual depression of a plunger 25 and the ejected discs descend down corresponding guideways 32 to settle within a Petri dish 55 in an accurate pattern and location e.g. with their centres at least 24 mm. apart. The depression of the plunger is translated through the angle member 27 into a limited horizontal (left-toright) displacement of a dispensing plate 36 within the confines of rectangular recesses in the stationary plates 28 and 31. Fingers (50, Figs. 5 to 7, not shown) on the dispensing plate eject the disc sideways from its cartridge into the adjacent guideway. The opening in the guideways tapers slightly inwardly from top to bottom and the axes are. flared outwardly. The cartridges are secured by their bridges, which fit into recesses in the plate 31, and by a lock plate 41 actuated by a thumb lock 44. The distance between the guideways and the Petri dish 55 is preset to between 1-5 and 3 mm. (the sensitivity discs have a tendency to float when dropped from too great a height) by rotation of a knurled ring 35 along a measured thread on extension piece 34. Three equally spaced radial ribs 51a extending between the annular shoulders 51 and 52 of the ring engage the rim of the Petri dish. Vessels of other sizes are accommodated by inverting the ring to present its flat surface.

Filed: 1971-05-13
Abstract: 1354151 Cathode-ray tube circuits RCA CORPORATION 13 May 1971 [15 May 1970] 14770/71 Heading H4T In a pincushion distortion correction circuit in which correction is effected by modulating the D.C. operating potential supply to the line deflection generator by a parabolic function of frame frequency the effect of such modulation introduces an undesirable secondary raster distortion caused by variations in the (line flyback derived) EHT voltage and to compensate for this the D.C. operating potential is further modulated by a function derived from the EHT voltage. Thus as shown in Fig. 3b the operating potential B + supplied to the horizontal deflection circuit 50 is modulated by the action of a saturable reactor 54 the control winding 54c of which is supplied via a voltage regulator stage 60 from the pincushion correction circuit 90. The latter is supplied at terminal B with a parabolic waveform of frame deflection frequency derived at terminal B, Fig. 3A, and operates in known manner to correct for side (East-West) pincushion distortion such as shown in Fig. 1. However, the variations produced in the operating potential B+ also results in variations in the EHT voltage which is derived via multiplier 80 from the horizontal output transformer 70 such variations introducing a secondary raster distortion such as shown in Fig. 2 and to compensate for this distortion a portion of the EHT voltage VB is derived from a voltage divider 77, 81 and supplied to the correction circuit 90 via a coupling circuit which includes a capacitor 85 to pass the video components in the waveform VB. This latter waveform is a close approximation to the required function but a closer approximation may be derived by the use of a capacitive voltage divider as shown in Fig. 4. The voltage regulator stage 60 also operates in known manner to maintain constant raster width with beam current changes and power supply fluctuations by further modulating the B + supply as a function of the voltage variations produced across the S shaping capacitor 58.

Abstract: 1467520 Protective arrangements TECHNION RESEARCH & DEVELOPMENT FOUNDATION Ltd 4 April 1974 [30 April 1973] 14992/74 Heading H2K A circuit protecting a 3-phase motor from the effects of phase-asymmetry in its supply comprises a sensor 19 in the motor picking up a signal associated with the leakage field during rotation of the motor and feeding it to an active filter circuit 23 which passes a band of frequencies centred on the second harmonic of the supply which is the frequency most affected by phase asymmetry, followed by two passive band rejection filters 25, 26 which attenuate the supply frequency and its third harmonic and feed the resultant signal via an amplifier 27 to a peak converter 28 whose output is a D.C. control voltage with an amplitude related to the peak value of the signal from the amplifier 27, this D.C. control voltage being compared with a reference value in a comparator 29 so that when the reference value is exceeded, as when phase asymmetry occurs in the motor, a switch is operated to disconnect the motor supply and/or operate an alarm. The sensor 19 is in the form of a tank circuit inductively coupled to the motor. To prevent operation of the switch due to transient effects a time delay circuit 34 is incorporated in the circuit, so that only phase asymmetry condictions lasting for longer than a predetermined time have an effect on the circuit. To protect against overload a current to voltage converter 51 is connected via a sensor 50 to one line of the motor supply and its output is fed to a threshold detector 53 so that if the supply current exceeds a predetermined value a switch is operated to disconnect the motor supply. In the case where phase-asymmetry exists in the supply before the motor is switched on an A.C. to D.C. converter output signal respresenting the instantaneous sum of the voltages in the lines of the supply is less than a predetermined threshold voltage and threshold detector 41 prevents the starting of the motor.
