Title: Method and apparatus for the automatic focussing of electron beams in electron optical apparatus
IPC: H01J37/21
Filed: 1974-12-20
Abstract: 1477030 Automatic focusing of electron beams NIHON DENSHI KK 20 Dec 1974 [24 Dec 1973 24 April 1974] 55263/74 Heading G3N and G3R An automatic focusing arrangement for an electron beam device converts the output of a detector into an electrical signal over a period of time during each scan of the specimen and compares successively received electrical signals to produce a control signal for changing the focal length of a condenser lens system in the arrangement step by step in synchronism with the scan. In the electron microscope shown, an electron beam 3 Fig. 4, is made to scan specimen 4 by the action of scanning coils 8x, 8y and focused by coils 6 and 18. Coil 6 is supplied from source 17 and the auxiliary coil 18 is supplied from controllable power source 19 and its excitation varied automatically by circuit 20 to give automatic focusing adjustment of the beam. The scanning signals are also applied to the display CRT and both the microscope and display are synchronized by pulses from a blanking signal generator 16. The output from detector 14 represents the diameter of the scanning beam and this output is converted into a D.C. signal by a storage counter 21, Fig. 5 and is gated for each succeeding line scan with alternate ones of two memories 24a, 24b which therefore contain signals from consecutive scans, and these are compared to operate a control signal generator 27. For this purpose if the present line scan signal exceeds the previous one, showing that the focus has improved a pulse from generator 26 is gated with distributer 28 and acts on converter El to apply a step of focusing current through adding circuit 29 to the auxiliary coil 18. If the next comparison is also positive a signal is applied to the converter to add a second step of current, but this step is reduced somewhat by attenuator f2. By this means successive steps of lessening magnitude are added until the optimum focus is exceeded. The comparator then produces a negative output and a negative step, suitably attenuated is added. The process continues until the optimum focus is obtained, the final stage of the distributer serving to operate stop pulse generator 32 and by opening gates 30, 31, brings the process to an end. The converting circuit may include a high pass filter and integrator to act as a storage counter and can employ integrator circuits instead of a memory store. In a modified construction the auxiliary coil may be located within the housing of the main focusing coil but is still separately energized.

Title: Determining the boiling points of liquids
IPC: G01N25/08
Filed: 1966-04-13
Abstract: 1,109,269. Photo-electric measurement of boiling point. MEPAG A.G. Dec. 13, 1966 [July 29, 1966], No.55833/66. Heading G1A. The boiling point of a liquid is measured by photo-electric investigation of the vapour bubbles formed when the liquid is heated. Liquid in a test tube 1 is heated by means of an oven 3, the temperature of which is monitored by a sensor 4. Light from a lamp 6 is transmitted through a heat proof glass light guide into the liquid, and reflected on to a cadmium sulphide photo-resistor 8 by any vapour bubbles, produced when the liquid nears the boiling point, passing the hole 7. The output of the detector 8 comprises pulses, of duration dependent on the time taken for a bubble to pass in front of the detector observation hole 7, which is of rectangular or square section. The amplitude of a pulse is dependent on the surface area of the bubble being detected. The voltage pulse occurring across resistor 9 is amplified by a transistor amplifier including input and output transistors 11, 12. The amplifier output is applied to capacitor 13 which charges to a voltage proportional to the length and amplitude of the pulse. The occurrence of further pulses (due to more bubbles passing the observation hole 7) maintains the capacitor in a charged state, and the voltage attained, or the discharge current through resistor 14 thus indicates the amount of vapour (in the form of bubbles opposite the observation hole) being produced at any one time. The resistor 14 may be replaced by a relay energizing coil and thus actuate the relay at a predetermined voltage which represents boiling of the liquid. The relay can control recording or indication devices or switch off the oven.

Abstract: 1398007 Pulverulent fuel burners VICTORIA STATE ELECTRICITY COMMISSION OF 8 Dec 1972 [9 Dec 1971] 56665/72 Heading F4T [Also in Division B2] Pulverized coal particles fed in an entraining vapour stream to a boiler furnace are segregated to the outer region of the stream by causing the stream to flow with substantially a potential vortex swirl about a straight vortex axis and with movement parallel to the axis so that the particles tend to be thrown out to the outer region of the stream and dividing an inner part of the stream from those particles in the outer region of the stream. As shown in Fig. 4, a burner and vortex separator combination 40 is mounted in a boiler furnace wall 41. Fuel particles and vapour enter a swirling stream at the end 44 of the duet defined between conical walls 42 and 43 of the separator from a contracting inlet (not shown). The burner end has a refractory nose 45 shaped to provide a return passage 46 through which fuel-lean vapour is drawn from the inner region of the stream in the separator duct and discharged to waste through a central tube 47. Straightening vanes 48 provide pressure recovery of the swirl energy in the waste vapour. The particle-enriched portion of the stream passes from the duct with swirling motion and is mixed with secondary air from a manifold 49 as it discharges directly into the furnace for combustion.

Abstract: 1405278 Data sorting INTERNATIONAL BUSINESS MACHINES CORP 12 Dec 1972  [16 Dec 1971] 57238/72 Heading G4M A data processing system is programmed to perform a sort operation upon records which are situated at dispersed addresses in a data storage device (e.g. magnetic disc), each record having a tag including a key value on a record address. The record tags are first sorted into sequential order by key value and the address portions of the tags as they are arranged in the tag sort are sorted into a set of numbered substrings using a known internal sort method (e.g. replacement selection). Each substring comprises a group of different tags arranged in ascending order of address value. The substrings are then merged during which the string number is added to the tag and the key and address portion may be deleted to leave a list of string numbers which lie in the same order as the records in the file. A distribution sort is then performed on the records, distributing into a number of buckets equal to the number of substrings and correspondingly numbered. The distribution sort is designed such that the records distributed to a given bucket are those whose addresses are in the substring which has the same number as the bucket, the buckets being arranged in sequential order of numerical value. At the completion of the distribution sort (which can be single or multi pass), a single sort pass of the distributed records produces a string of records arranged in sequential order of key value, the buckets being read in the reverse of the order in which the corresponding strings were generated. The average bucket size is twice as large as that of the main store.
