Abstract: 865,666. Cathode-ray tubes. MULLARD Ltd. Nov. 1, 1957 [Jan. 30, 1957], No. 3281/57. Class 39(1). A cathode-ray tube in which scanning is effected in one dimension only has an elongated luminescent target T, Fig. 1, and one or a pair of coils L, L<SP>1</SP> for setting up a transverse magnetic field. The electron gun may be located in a neck N 1  or N 2 , or in a neck coaxial with the envelope. The scanning may be effected by varying the intensity of the magnetic field and/or the direction of entry of the beam into the field, e.g. by means of a magnetic or electrostatic deflection system, or by varying the initial velocity of the beam. The magnetic field may be uniform or may increase in intensity away from the target in order to improve focusing of the spot in the scanning direction or towards the target in order to improve focusing in the transverse direction. The lower limb Lo of, a magnetic field coil may be shielded by a magnetically permeable channel member P to obtain the field configuration shown in Fig. 5, or the upper limb L1 may be divided into separate parts L1<SP>1</SP>, L1<SP>11</SP> to obtain the field configuration shown in Fig. 7. The field intensity may be increased along the tube by means of a pair of converging coils L1, L1<SP>1</SP>, Fig. 12, to provide good focusing at all points along the target. Instead of using coils permanent magnets may be used, e.g. as shown in Figs. 15 to 18. A number of magnets, graded in strength or spacing, may be distributed along the tube. Electromagnets may be used. Additional magnets may be provided to correct the shape of the spot on the target. In a colour television tube with a multi-line target Tr, Tg, Tb, Fig. 22, colour selection may be obtained by means of a pair of spotwobbling electrostatic deflection wires or strips Ds, or a three-gun system may be used. In Fig. 22 a magnetic shield Pd is provided across the tube and an accelerating field is set up between the shield and the target. The axes of the target colour strips may be set at a small angle to one another, and the strips increased in width along the tube. The strips may also curve inwardly at the end of the tube remote from the gun. The target may include a fourth phosphor strip fluorescing white which may be brought into use for monochrome working by rotating the tube. Spare sets of phosphor strips may be provided on the inner wall of the tube and brought into use when required by rotating the tube. Dynamic focusing of the beam may also be used. Specifications 827,851, 846,544. 865,663 and 865,665 are referred to.

Abstract: 1374922 Measuring the thermal conductivity of a specimen EUROPEAN ATOMIC ENERGY COMMUNITY 25 Jan 1972 [18 Feb 1971] 3414/72 Heading G1A In an apparatus for measuring the thermal conductivity of a specimen 1 supported on tungsten spikes 2 within a gas tight vessel 4, two CO 2  lasers 10 and 11 illuminate ipposite sides of the specimen 1, as shown, with one laser beam being modulated by an adjustable chopper 14 comprising a disc with blades on opposite quadrants such that the modulative frequency is between 0.05 Hz and 10Hz and modulative depth is equal to or less than one half. Two radiation sensors 7 and 8 such as photo-diodes respond to variations in radiation due to temperature modulations and their sinusoidal signal outputs are transmitted to an electronic evaluation system, where the phase shift of one signal relative to the other is determined since this is directly proportional to the thermal conductivity of the specimen. The absolute temperature of the specimen may be measured with the aid of a pyrometer 9. As shown in the Fig. the laser beams are directed into the vessel 4 by reflectors 12 and 13, and these reflectors may be adapted to provide faster scanning of the respective surfaces of the specimen to ensure homogeneous heating of the specimen.

Abstract: 1409701 Weapon control system WILLIAM WAHL CORP 25 Jan 1974 03500/74 Heading F3C A weapon control system for changing the state of one or more of a group of multistate weapon actuating devices comprises at least one remote station, the or each station including actuator means 12 for effecting a change of state of one of the devices, state sensor means 14 for sensing the states of the devices and transmitting status words each including a representation of the sensed state of the corresponding device. A command station including sensor command means 16 is provided for generating test words for transmission to the state sensor means 14 and means to actuate the sensor means 14 and cause transmission of the status words. A command status memory 18 receives and stores the status words transmitted from the state sensor means 14. Means 20 for selecting a word having a predetermined state from the command status memory is provided and reads out the selected word as an actuator word. The actuator word, in use, is transmitted to the state charge actuator means 12 to effect a change of state of one or more of the multistate devices. When a plurality of remote stations are provided, each is provided with a transceiver which includes means for identifying a unique address contained in an actuator or test word that uniquely identifies the remote station and uniquely identifies and selects one of the devices at the station. The link between the command station and the remote stations may be a single line, time being shared between outgoing and incoming signals with respect to the command station. Firing prerequisites are also fed to the remote stations. The energy for changing the state of the devices is obtained from the energy contained in the words. The arrangement of the weapon control system is such that the remote stations are interrogated in turn as to the state of the weapons at the respective station in cycles, the cycle being interrupted if the operator wishes to actuate a weapon. Should a weapon not "operate" correctly a "hung" signal is produced at the command station.

Abstract: Apparatus for applying liquid to a web or sheet of material comprises a trough for the liquid, a pair of mangle rolls mounted side by side and dipping into the liquid to form a nip close to the level of the liquid, a liquid supply, a feed pipe connecting p  the supply to the trough and means for controlling the liquid feed to maintain a constant level in the trough.  In a modification, the rolls may serve to support endless bands passing through the liquid and the nip and may be arranged so as to have the effect of upwardly extending the nip above the rolls.  Fabric 4, Fig. 1, from a roll 5 passes around roll 8 and guide rolls 9 in a bath 10 and is directed upwardly to the nip of a pair of rubber or fabric-covered rolls 11.  The trough 10 is filled with liquid to a level 12, slightly below the nip of rolls 11. The trough 10 is supported by standards 14 pivotally supported by links 15 from the frame and by links 17 from a rotatable shaft 16, the links 17 being provided with balance weights 18.  A worm wheel 20, operated by a hand wheel <PICT:0469908/IV/1> <PICT:0469908/IV/2> 23 through a shaft 22 and worm 21, is fixed to the shaft 16 and serves to lower the trough from operable position.  The left-hand roll 11 supported in slidably mounted bearings is urged to the right by a pressure bar 27 passing through a threaded block 31 on a lever 30, which is urged to rotate clockwise about a pivot 32 by a bell-crank lever 33 weighted at 34.  The pressure between the rolls 11 can be adjusted by rotation of a hand wheel 40 and quickly released by a cam 37 rotated by a hand lever 36.  Liquid is fed to the trough 10 from a closed container 41, Fig. 3, by a pipe 43.  A fall in level of the liquid permits air to pass through an opening 44 in the cover of an extension 42 of the trough and by pipes 46, 47 to a point above the level of the liquid in the container 41, so that liquid flows through pipe 43. When the desired level is reached a float and needle 50 closes a valve 45 and stops the flow of air. When charging the container 41, any liquid in the pipe 47 may be drained by a three-way cock 51 and drain pipe 52.  Specifications 470,333; and 470,334, [Group XIII], are referred to.
