Title: Screen-grid tube
IPC: H01J19/66
Filed: 1968-04-26
Abstract: 1,220,469. Thermionic valves. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 26 April, 1968 [27 April, 1967], No. 19865/68. Heading H1D. A screen grid tube has electrode supply conductors 1, 2, 3 in the form of coaxial cylinders connected to the cathode 5, control grid 6 and screen grid 7 respectively from the inside outwards, and the characteristic impedances Zg 1 k and Zg 2 g 1  of the lengths of coaxial line formed by the control grid and cathode supply conductors, and the control grid and screen grid supply conductors respectively, are selected such that the ratio obtains, where Cg 1 g 2  and Cg 1 k are respectively the pure electrode capacitances between the control grid and screen grid and between the control grid and cathode. This construction compensates for unwanted damping in the input and output circuit of an amplifier resulting from coupling between the output and input of the tube through the cathode lead inductance. The formulation of the ratio of impedances and electrode capacitances is given in detail, and if it is assumed that the effect of the cathode lead inductance lies solely within coaxial supply conductor 1 then the equality sign in the ratio holds; however since the connection of cathode to earth may also contain an inductive component this effect may be compensated by selecting the impedance ratio somewhat less than the capacitance ratio.

Patent GB-749609-A (GB)
Title: Method of inductively hardening the surfaces of rolls
IPC: C21D9/38
Filed: 1953-07-17
Abstract: A method of inductively hardening the surface of cast or wrought rolls comprises gradually heating the surface of the rolls until the surface temperature is fairly uniform and below the hardening temperature and then raising the surface temperature to the hardening temperature and quenching.  The fairly uniform temperature, i.e. above 600 DEG C. and preferably 750 DEG C., may be attained by the use of an inductor surrounding the roll and moved relatively thereto during which time the roll may be rotated, or by an inductor loop running the length of the roll and partly surrounding it, the roll being rotated.  The heating may be performed in such a manner as to prevent over-heating of the ends of the rolls and may be step-by-step, preferably three steps.  Two such heating treatments may be used, the roll being cooled between each heating.  The heating to the hardening temperature may be carried out rapidly and after quenching the roll may be stress relieved or tempered also by induction heating.  The frequencies used may vary from mains frequency to 500 or 2000 cycles per second depending on the size of the roll.

The friction surface 13 may comprise the inner surface of the drum per se or, if the component is of aluminium, it may be machined and anodized, or it may comprise helically wound wire (Fig. 6, not shown) or a metal band 15 (Fig. 2) fitted, locked, or metallurgically bonded to the drum. The band 15 may, as shown in Figs. 5 and 9, be formed with bosses drilled to receive bolts 12 or 60 respectively.

Abstract: 330,424. Brett, E. St. M. July 2, 1929. Sighting-apparatus for aerial navigation. - A sighting-instrument to be used on aircraft for determining the drift angle and the ground speed comprises a horizontal convex lens z<1> which projects an image of the ground on to a vertical lens z, an arrangement of mirrors f being interposed between the lenses so that an erect and unreversed image is produced on the surface of the lens z. Mounted adjacent the lens z is a rotatable ring x carrying a pair of parallel bars e on which is mounted a slider d. The ring is turned until the apparent direction of movement of an object on the ground is parallel to the bars h. The drift angle is then read on a scale g on the lens in conjunction with a pointer on the ring. The bars e are marked with altitude scales so that the ground speed can be found at a known altitude by setting the slider d to the appropriate altitude on the scale and timing the passage of the image of an object on the ground from the edge of the slider to the zero of the altitude scale.

[Also in Group XI] A gas turbine combustion chamber comprises a multi-vaned air swirler 1, 2 and a shutter device having the form of a set of sectoral vanes 4 equal in number to the vanes 1 of the swirler, the air swirler and shutter device being capable of rotation relatively to each other so as to vary the areas of the outlet orifices of the swirler, and means are provided for causing the relative rotation. Each swirler vane 1 has a baffle plate fixed thereto of the same form as the corresponding shutter vane and lies against it. A shroud 8 having ports 19 is disposed around the burner 7 and carries pegs 11 which engage in helical slots 10 in the hub 2 of the air swirler so that axial movement of the shroud 8 by means of the sleeve 9 causes the hub 2 and swirler vanes 1 to rotate relatively to the fixed shutter device 4. Axial movement of the shroud 8 also varies the quantity of air admitted by the shroud by varying the space between the shroud and the burner tip and by varying the area of the ports 19 in the shroud uncovered by the ports 21 in the swirler hub 2. The control means may be actuated manually or automatically in dependence on the rate at which fuel is supplied to the burner.

A ferrous member is coated with aluminium oxide by anodic deposition from an aqueous bath containing dissolved monoaluminium phosphate using D.C. and a consumable aluminium cathode, the coated member then being removed from the bath and dried at elevated temperature, yielding an insulating coating. Preferably the bath is of pH 1 to 5 and the monoaluminium phosphate may form 16 to 50% by weight of the aqueous solution. Typically a silicon steel plate is degreased with trichlorethylene and is then immersed in a bath at 70‹ F. containing by weight 1 part monoaluminium phosphate to 2 parts water, giving a pH of 1À5 and coating is effected by applying 8 volts for five minutes. The anodic deposit which is gelatinous may be baked at 800‹ F. for 45 seconds, the coated member preferably being slowly withdrawn from the bath while current is still flowing. Improved electrical qualities are obtained if the bath contains about 4g/1 NaF.
