A cathode-ray tube gun consists of cathode 5, modulator 7, first anode 8 in the form of a plate, second anode 9 with cylindrical aperture of small diameter flaring to a large diameter, and third anode 10. The small diameter portion 18 of second anode 9 is cylindrical or conical and the large diameter part 17 is part spherical. Anode 9 may consist of a block of metal, or of insulating material with a conductive coating, or of sheet metal. Anode 8 is triangular and supported at the corners on the steatite rods 21. The other electrodes are supported by triangular flanges. Anode 10 is connected to a metal coating on the bulb, and may be constituted by the metal coating or may be of plate form. The arrangement is such that with appropriate voltages a first cross-over is formed " near to the first anode " and the first, second and third anodes focus the beam to " a small cross-section which remains substantially constant up to the screen." These expressions are defined in the Specification. With voltages, dimensions and spacings specified in the Specification, it is stated the neck length L is brought down from about the 16 to 18 cms. of a conventional tube to about 12 cms.

Abstract: 1,039,563. Textile folding apparatus. THOMAS BROADBENT & SONS Ltd. Feb. 4, 1964, No. 6169/63. Heading D1S. A flatwork folding machine comprising at least one fold station embodying two pressure members presenting a bight therebetween and adapted to receive workpieces therebetween and propel them therethrough, the fold station being disposed so as to provide a normal workpiece path which passes adjacent to and beyond the bight between said pressure members, and means actuated in dependence on the progress of workpieces beyond the bight between the pressure members for forming a bend in a workpiece intermediate the ends thereof and for directing the bend into the said bight, is characterized by transfer means movable from a normal position clear of said workpiece path to a position in which it obstructs said path and directs the leading end of a workpiece into the bight between the pressure members to avoid folding thereof at said fold station. In the arrangement shown a workpiece is fed by a plurality of tapes 20 so that in normal operation its leading edge passes downwardly between an air jet pipe 60 and a pair of fold rollers 36, 37 and at an appropriate time the air jet is operated by valve 63 so as to fold the workpiece and feed it between rollers 36, 37. Should it be desired not to make a fold, roller 37 is pivoted upwards to the dotted line position. Connected to the roller 37 support means by limbs 68 is a transfer plate 64 which is thus moved by the roller movement to a corresponding dotted line position so that the leading edge of a workpiece is fed directly across roll 36 on to delivery conveyer 32. The roller 36, 37 are preferably formed of a number of spaced rubber-sheathed pulleys with guide fingers 54, 55 therebetween.

Title: Improvements in or relating to apparatus in, or for use in, radar installations
IPC: G01S7/06
Filed: 1956-02-28
Abstract: 793,661. Photo-electric control TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 28, 1956 [Feb. 28, 1955], No. 6243/56. Class 40 (3). [Also in Group XL (c)] The invention relates to means for producing a voltage which is a function of the range, bearing or elevation of a radar target. In one embodiment in which the voltage is a function of target range, R is a pulse radar of known kind and includes a sweep circuit 6 for producing a range sweep when its output is applied to one pair of deflection plates of cathode-ray tube 7. The output from the receiver 3 is fed to intensity modulate the tube beam. In front of the fluorescent screen is arranged a mask 9 with two parallel adjacent slots S1, S2, running across it at an angle of about 45 degrees with respect to the deflection system. Any light passing through the slots is fed respectively by lenses 11 and 12 to photo-cells 13 and 14. An opaque screen 10 is arranged between the two optical systems. In use, potentiometers 16 coupled to the remaining deflection system are adjusted to move the range sweep perpendicular to its length and bring the target indication 18 to the boundary between the two slots. The outputs from the two cells are fed in opposition to the D.C. amplifier 15 and do not produce any amplifier output until the target range alters and one photo-cell output exceeds the other. When this occurs the amplifier output is superposed on the voltages from potentiometers 16 and causes the range trace to move in a direction tending to bring the target indication back on to the line between the two slots. The targetindication is thus tracked automatically and the potential applied to the vertical deflection system is proportional to the target range. In order to maintain the trace in a position deflected from the original a continuous deflection potential from amplifier 15 is essential and thus the target spot 18 does not move up and down exactly opposite the screen 10 but is displaced from it an amount dependent on the distance from the initial setting position. Thus the output voltage does not accurately follow the range. However, if an integrator 20 is inserted this error is overcome. Use of a long persistence screen material provides a memory effect and noise does not affect tracking. If an integrator 20 is used there is also a velocity memory effect. By mounting a wedge-shaped reflecting prism along the centre line of a single slot a modified optical system can be arranged with the two photo-cells one on either side of the end of the tube (Figs. 4 and 5, not shown). If the cathode-ray tube sweep is synchronized with the azimuth or elevational scanning of the directional radar aerial instead of being a range sweep, voltages proportional to bearing or elevation can be derived (Fig. 6, not shown).

The oscillatory anode circuit LC is tightly coupled to the grid coil L<1> to give positive feedback, and a resistor R<1> in the cathode lead of the valve V<1> gives controllable negative feedback. The pulse is applied in negative sense to the grid of a damping-valve V<2> cutting off current through that valve and causing the valve V<1> to burst into oscillation.

Title: Process for the reaction of halogen-containing organic aluminium compounds with olefines
IPC: C08F10/00
Filed: 1959-02-24
Abstract: Olefines are reacted with compounds of formula XA1R2 in which X represents a halogen atom and R represents a hydrocarbon radical containing no unsaturated carbon-carbon bonds on the carbon atoms bound to the aluminium, the reaction being effected in the presence of an organic aluminium compound in which all three valencies of the aluminium are bound to carbon, or in the presence of a dialkyl-aluminium hydride, an alkyl aluminium dihydride or an aluminium hydride as catalyst.  R may be any aliphatic, alicyclic, substituted or unsubstituted aromatic, mixed aromatic-hydroaromatic or mixed aliphatic-alicyclic hydrocarbon radical and is preferably a benzyl or alkyl group.  The ethylene adds on between the aluminium atom and the atoms X and groups R. Olefines may be displaced from compounds of formula XA1R2 by reacting with an olefine other than ethylene, at least one R group being other than that corresponding to the displacing olefine.  The catalyst may be inactivated after the reaction if desired by addition of A1X3 or the corresponding alkyl aluminium dihalide or sesquihalide.  The reaction mixture may advantageously be treated with a potassium halide and the olefines distilled off from the complex obtained.  Bis[b -(cyclohex- 3-enyl)- ethyl] aluminium monochloride is reacted (Ex6) with ethylene to yield a product of formula <FORM:0879269/IV (b)/1> This on oxidation yields an alcohol mixture of average composition <FORM:0879269/IV (b)/2> The above organo aluminium compound may be decomposed with methanol and hydrolysed with dilute sulphuric acid to give a hydrocarbon mixture containing n-butane, n-hexane, n-octane, 1-ethyl-3-cyclohexene, 1-n-butyl-3-cyclohexene, 1-n-hexyl-cyclohexene and 1-n-octyl-3-cyclohexene.
