Title: Improvements in or relating to electron-microscopes
IPC: H01J37/153
Filed: 1958-01-03
Abstract: 869,850. Electron microscopes. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 3, 1958 [Jan. 3, 1957], No. 315/58. Class 39(1). Astigmatism in an electron microscope is corrected by using one or more auxiliary four pole systems and adjusting the excitation of each system to two successive values such that for each of the two values, the image projected on the microscope screen shows disfigurements of like magnitude, the mean of the two excitations being taken to produce the optimum correction. When only one system is used it must be rotatable so that a line 12 or 13, Fig. 3, joining opposed poles such as electrodes 1, 3 coincides with the direction of the astigmatism to be corrected. The excitation of the poles 2, 4 is then adjusted by means of a slider 11 of potentiometer 10 so that a clearly visible disfigurement is produced, and a like disfigurement is obtained by moving the slider in the opposite direction, the mean position of the slider being taken as the Optimum adjustment. Resistors 7, 8 may constitute a further potentiometer with the point 9 being replaced by a slider so that the excitation ofpoles 1, 3 may also be varied. In a preferred modification magnetic poles 1-4, Fig. 4, have winding 17 applied. by a similar bridge, but resistors 7, 8 have toppings 14, 15 at equal and opposite potentials with reference to point 9. By switching commutator 16. alternately from 14 to 15, slider 11 may be adjusted so that like disfigurements occur in each case the commutator 16 then -being connected to point 9: Errors due to estimating the mean position of slider 11 are thereby eliminated. When two such systems are used, the poles of -the second system are placed between those ofthe first and neither need be rotated. The optimum adjustment for each system is obtained as described above.

Title: Improvements in and relating to indicating instruments
IPC: G01N23/08
Filed: 1951-01-12
Abstract: 723,866. Sorting articles by radio-activity. ISOTOPE DEVELOPMENTS, Ltd., and FEARNSIDE, K. April 15, 1952 [Jan. 12, 1951], No. 930/51. Class 40 (3). Apparatus for examining each of a series of articles 10 (Fig. 1) carried by a conveyer 11 by determining the absorption of radio-active rays from a source 12 by each article as sensed by a detector 13, is characterized in that the presence of an article 10 between a light source 14 and a photo-electric switch 15 causes a counter 16 to measure the output from detector 13 for a predetermined time interval, thereby operating a rejector device 19 when a defective article is detected, and a warning device 18 when the counting rate is too low. The photoelectric switch comprises a photo-cell PC (Fig. 2) which, on receiving light from the source 14, changes the bias on a valve V1 to cause energization of a relay RA in the anode circuit. A further valve V2 has a normally energized relay RB in its anode circuit, but operation of RA closes contacts RA1 to reduce the grid voltage and anode current of V2, thereby releasing RB. Thus relay RA is energized and RB unenergized until an object 10 interrupts the light falling on photo-cell PC, RA falls, and after a short interval determined by the charging rate of a condenser C1, RB operates. During this time interval relay contacts RA2, RB1 are both closed, and a Geiger counter GC in the radioactive detector 13 is operated to receive radiations from the source 12 through the object 10, feeding the resultant pulses via a condenser C2 to a multi-vibrator V3, V4 which sends a series of short pulses of equal duration to a pair of diodes V5, V6 associated with a condenser C4 which integrates the pulse voltages. At the end of the interval relay RB operates, contact RB2 changes over and the voltage on C4 is fed to a valve V7. If this voltage is above a level determined by the slider of a potentiometer R22, the anode current of V7 energizes a relay RC which operates an air valve to remove the faulty object 10 from the conveyer 11. The pulses from the multi-vibrator V3, V4 are also fed via an averaging circuit R24, R25, C5 to a valve V8, so that with the normal pulse rate the anode current of V8 operates a relay RD, and extinguishes a warning lamp, but if the pulse rate falls, the relay RD falls and the lamp is lit. The apparatus may be used to detect the height to which a container is filled, or to detect the absence of one item from a container, or to determine the weight of a packet.

Title: Microcomputer data processing systems permitting bus control by peripheral processing devices
Inventor: DEAN MARK EDWARD
IPC: G06F13/28
Filed: 1990-05-31
Abstract: A microcomputer system includes a main processor (1), a memory (3) and a direct memory access controller (DMA;4) effective to control direct data transfer between the memory and input<sub>/</sub>output devices on channels. Bus control for data transfer is switchable between the DMA and processor by a hold request/acknowledge handshaking sequence between the DMA and processor. A control line (27) from the channels is activated by a peripheral processing device on a channel when it wishes to gain control of the busses for data transfer. Logic means co-act with the handshaking sequence to determine which device gains control of the busses. This logic is responsive to the DMA address enable output (AEN), the hold acknowledge output of the main processor (HLDA) and the channel control line output (-MASTER). When all these are deactivated, control passes to the main processor, when AEN and HLDA only are activated, control passes to the DMA controller and, when all three are activated, control passes to the peripheral processing device.
