Title: Improvements in or relating to four-terminal networks and to signal distribution systems incorporating such networks
Inventor: O'DONOVAN HARRY MAURICE
IPC: H03H7/01
Filed: 1953-11-02
Abstract: 798,255. Balancing networks. PYE, Ltd. Oct. 6, 1954 [Nov. 2, 1953], No. 30215/53. Class 40(8). An impedance-transforming circuit for feeding signals into and deriving signals from a twoconductor transmission line includes a transformer and means for balancing the line comprising an inductor L in series with each line and a single adjustable conductive or magnetic core D associated with both coils. The inductors L are combined with the leakage inductance of the transformer and the input capacitance C2 of a valve circuit to form a correctlymatched filter circuit in the manner described in Specification 798,256. The core D is arranged to be movable in such a manner that the total inductance of the two coils L remains constant. The transformer may be totally shielded or arranged so that its flux cuts the coils at rightangles. An electrostatic shield may be arranged between the coils of the transformer. Alternatively, the transformer can be wound as a toroidal coil. The insulating capacitances C1 form part of the filter network and may be variable.

Abstract: 924,939. Nuclear fuel material. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug. 10, 1961 [Sept. 5, 1960], No. 30616/60. Class 39 (4). Ceramic fuel material for nuclear reactors is produced by dissolving a plutonium compound in an organic solvent, mixing this solution with an organic polymer binding agent, and then adding this final mixture to powdered uranium dioxide, compacting the product and sintering. The preferred compound is plutonyl dinitrate and the preferred organic solvent is methyl isobutyl ketone (hexone). Suitable organic binders specified are polybutyl methacrylate, polyvinyl esters, and other polymethacrylate esters; and these binders may be plasticized with a suitable agent, e.g. glycerol, dibutyl phthalate, the solvent for the binder preferably being hexone, but toluene, acetone, methyl ethyl ketone, trichloroethylene, carbon tetrachloride or any suitable mixture thereof can be used. The solution of plutonium in hexone is prepared by successively contacting at pH2 an aqueous solution of plutonyl nitrate containing aluminium nitrate with portions of hexone. The sintering of the final compacted mix may be accomplished either in an atmosphere of hydrogen at 1500-1700 C. or an inert atmosphere of argon at 1300-1500 C. or it can be effected at 1400-1600 C. in an atmosphere of CO 2  or a mixture of CO and CO 2 . Prior to sintering the compact may be heated to 200-250 C. in an oxidizing atmosphere, e.g. oxygen. Specifications 881,883 and 910,517 are referred to.

Title: Scanning electron microscope
IPC: H01J37/22
Filed: 1974-07-10
Abstract: 1432887 Scanning electron microscopes NIHON DENSHI KK 10 July 1974 [27 July 1973] 30639/74 Heading H4F [Also in Division H1] A scanning electron microscope having a specimen 3 includes a set of concentric annular electron detectors 8a, 8b, 8c, 8d. The outputs of two of the detectors 8a, 8b may be amplified 9, 10 and the ratio of these two signals formed at 16 to provide a signal which is characteristic of the material of the respective portion of the specimen 3 (e.g. gold or copper). This signal is compared with a reference value at 17 to control gates 14, 15, gate 14 being opened when the output of comparison circuit 17 indicates gold and gate 15 being opened when the output o f  comparison circuit 17 indicates copper; this provides a greater contrast of display on cathode-ray tube 12 being the copper areas and the gold areas of specimen 3 than if a single detector were used. In an alternative embodiment (Fig. 4, not shown) the outputs of four detectors 8a-8d are fed, in pairs, to three dividing circuits each connected via a respective comparison circuit to a respective gate. The gates are controlled so as to pass the signal from the inner detector 8a to different cathode-ray tubes when different materials are detected so that each cathode-ray tube provides a display of the distribution of a different material in the specimen. In a further embodiment (Fig. 5, not shown) for observation of crystalline specimens the outer and inner detectors 8a, 8d correspond to diffraction rings of the scattered electrons, one cathode-ray tube being supplied with the sum of the outputs of detectors 8a, 8d and a second cathode-ray tube being supplied with the output of detector 8a minus the background output of detector 8b. In alternative embodiments backscattered electrons are detected, the incident electron beam being incident on the specimen at rightangles (Fig. 7, not shown) or at 45 degrees (Fig. 8, not shown). The annular detectors 8a-8d may be formed of arrays of tiny detectors (Fig. 9, not shown).

Title: Semiconductor switching circuit arrangement

Filed: 1961-08-25
Abstract: 975,832. Transistor switching circuits. J. B. M. CLIFTON. Aug. 25, 1961 [Sept. 29, 1960], No. 30664/61. Heading H3T. To minimise the power loss during the transitory period of switching a transistor or S.C.R. from the " off " condition to the " on " condition, a saturable core reactor is connected in the output circuit to limit the current flow through the transistor or S.C.R. As shown in Fig. 1 a reactor 17 is connected in the output circuit of a transistor 8 which is rendered conducting and non-conducting by pulses from square-wave generator 9. During the transient time when the transistor is switched from cutoff to the " on " condition, the reactor limits the collector current to the magnetizing current, but when, due to the voltage drop across the reactor, the reactor becomes saturated, its impedance reduces to zero and full current in the output circuit is established substantially instantaneously. The reactor 17 is demagnetized during the cut-off period of the transistor by current passing through winding 19 of the reactor connected across the collector bias supply 13. Fig. 2 shows a push-pull arrangement of the circuit of Fig. 1.

IPC: B65B3/26
Filed: 1961-08-29
Abstract: 943,129. Controlling liquid levels. DISTILLERS CO. Ltd. Aug. 3, 1962 [Aug. 29,1961], No. 31052/61. Heading G1H. In an automatic filler device for filling containers to a predetermined level in which a filler tube 1 is connected through a pipe 7 to a liquid supply source and a valve 4 is provided for controlling the passage of liquid through the tube 1, the valve 4 operating in response to an increase in air pressure in a dip tube 8 due to the rise of liquid therein, the valve 4 is operated by a two stage pneumatic control cylinder 6, the valve 4 being partially closed by operation of the first state when the container is partially full and completely closed by operation of the second stage when the container is filled to a predetermined level, the variation in pressure necessary to operate each stage of the cylinder being produced through a pneumatic relay by movement of a baffle 11 in an air jet in response to the air pressure increase in the dip tube 8. In the arrangement shown as the liquid rises in the dip tube 8 the increase in air pressure therein collapses a metal bellows 10 to move the baffle 11 away from a nozzle 12 towards a nozzle 13 thus resulting in a pressure change in a pipe 15 which pressure change is amplified through a restriction 15a and, by a known pneumatic relay, operates regulating means to cause compressed air to be fed to a line 17 and to reduce pressure in a line 17a to atmosphere to operate the first stage of the pneumatic control cylinder. The first stage operation of the cylinder firstly closes the valve 4 to the dotted line position to reduce the liquid flow rate through the opening 3. As the liquid continues to rise in the container the baffle 11 continues to rise to cause further pressure changes in the pipes 15,16. The pressure change in pipe 16 is now amplified through a restriction 16a and, by a pneumatic relay, to operate regulating means associated with air supply lines 18,18a to cause a reduction of air pressure to atmosphere in line 18 and an increase in pressure in line 18a to operate the second stage of the pneumatic control cylinder to close the valve 4.
