Title: Electric discharge tube including an electrode comprising a metal tube in the wall of which slots extend in the axial direction of the tube
IPC: H01J19/38
Filed: 1971-11-18
Abstract: 1360662 Thermionic valves PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 Nov 1971 [21 Nov 1970] 53603/71 Heading H1D A discharge tube includes a metal tubular electrode 11 with narrow and wide strips 16, 17 formed by slots which extend axially in a side wall 13 and into an end wall 14, the slots bounding the wide strips extending furthest into the end wall. The electrode is formed by a spark erosion process which can lead to buckled shortened narrow strips. The extended slots 18, 19 allow the extensions 10 of the wide strips to bend and prevent the strips themselves buckling which could result in flash over. The electrode is rectangular or cylindrical of Cu, Mo or steel and is used as a control grid in a ceramic tetrode or triode.

Abstract: 1,163,290. Forming tubes from strip. YODER CO. 2 Dec., 1966, No. 54011/66. Heading B3E. A roll unit for, a tube mill, i.e. for apparatus for bending, by engagement with rollers, strip passed longitudinally therethrough to form longitudinally seamed tube, for forming tubes of different finished diameters, comprises a stand adapted to be positioned transversely to the length of the tube mill, oppositely inclined slide tables on each side of said stand, roller supports on each slide table mounted for movement therealong, and strip-contacting rollers mounted on said roller supports. Metal strip, is bent up into tubular form by passage between rollers of roll stands 4, 5, 9, 13, 24, 30, 31 and over rollers 96 of multiple roller assemblies 6, 10, 14, 25 between the roll stands. The longitudinal seam of the tubing thus formed is welded by means 33 and the tubing is drawn out by means 34 to be severed into lengths. An upper roll 52, Fig. 4, of the roll stand 5 may be replaced by a unit 108, Fig. 5, having rolls 109. The assembly 6 comprises shafts 85, 94 extending, one on each side of the mill, between the roll stands 4 and 5 and carrying, on brackets 97, rolls 96 engaging the strip. The shafts 85, 94 are supported by slides 82, 92 adjustable by screws 87, 93, 106 on inclined slideways 75, 76, 105, supported by stands 8, 7. The adjustment, to suit various widths of strip, is such that the rolls 96 on opposite sides of the mill move in paths which intersect on a horizontal line extending longitudinally of the mill and aligned with the bottom of the finished tube. The assembly 10 is similar to the assembly 6 and the shafts 112 thereof are in line with the shafts 85, 94 of the assembly 6. The slope of the slideways increases from the entry to the exit of the mill. The assembly 14, Figs. 9, 10, has four roll-carrying shafts 130, 131, 132, 133, the shafts 130, 133 being carried by adjustable columns 149, 150. The assembly 25 is similar to the assembly 14 but has in addition a longitudinally-extending vertically-adjustable beam carrying a series of rolls to engage the central outer part of the strip. The slideways may be adjustable in inclination by screw means, Fig. 20 (not shown). The rollers on each side may be adjusted simultaneously by screw and common bevel gear means, Fig. 21 (not shown).

Title: Pulse-echo distance-measuring system
IPC: H03K7/00
Filed: 1968-11-20
Abstract: 1,203,850. Echo distance-measuring. BENDIX CORP. 20 Nov., 1968 [28 Nov., 1967], No. 55017/68. Heading H4D. In a pulse echo-distance measuring system the transmitter output is sampled to develop a signal which controls the width of the pulse which modulates the transmitter. The invention is described as applied to a radar altimeter with a transmitted pulse width also controlled in accordance with altitude, e.g. as in Specification 955,527. The transmitter oscillator 60 is gridpulsed; the output of a detector 66 applies a signal to a pulse width circuit 74 which is fed also by a signal dependent on altitude. Circuit 74 output and that of a trigger pulse generator 82 control the grid pulsing circuit 80. The trigger pulse is obtained from the leading edge of a pulse originating in synchronizing generator, Fig. 2 (not shown), and sets a multivibrator 100 for a variable period during which a pulse 14, Fig. 1 modulates oscillator 60; the multivibrator is reset by the circuit of transistor 114. The latter circuit is controlled by a signal from circuit 74 to establish a charge on a capacitor 122 which determines the pulsing period of the transmitter oscillator. In the operation of circuit 74, a " range " signal is combined with the output of a control circuit 72 which effectively integrates samples of the output of the transmitter to compensate for changing characteristics, e.g. due to temperature.

[Also in Division F2] A line firing gun comprises a pressure chamber 17 for containing compressed gas and a valve 20 for releasing gas from the chamber to project a projectile from the gun. The valve 20 is mounted within the chamber 17 and is provided with a firing rod 22 projecting through the wall of the chamber 17 opposite the valve seat, the area provided by the firing rod 22 and a seal 25 therefor for gas pressure to act in a direction away from the valve seat being slightly less than the effective area of the valve 20 for gas pressure urging the valve 20 against the valve seat. The rear end of the firing rod 22 has a boss 32 surrounded by a spring loaded sleeve 28. The sleeve 28 is urged forwardly to cock its spring 26 and is held in the cocked position by a spring loaded projection 29. Actuation of a trigger 31 depresses the projection and allows the sleeve 28 to move rearwardly, shoulders 27 of the sleeve striking shoulders 33 of the boss 32 to lift the valve from its seat to eject the projectile. The projectile may comprise a tubular portion closed at one end by a moulded rubber nose the line being attached to a piece of lead set into the nose and passing through a slit in a piece of felt at the open end of the tubular portion (Fig. 4, not shown). In a further embodiment the projectile comprises a tennis ball cover filled with a hard setting rubber composition in which are dispersed lead shot (Fig. 6, not shown).

[Also in Division F2] An energy absorber comprises a pair of telescopically related members having balls or rollers engaged therebetween such that relative movement of the members causes deformation of both members by rolling of the balls or rollers thereover. Fig. 2 shows a steering column in which the inner section 20 is secured to section 18 by injection-moulded plastics shear pins 22. The outer tube 24 is supported by a bracket 32 having slots 34 to accommodate mounting capsules 36 receiving hanger bolts 40 which depend from the vehicle cowl structure. The capsules 36 are secured to the bracket 32 by plastics shear pins 38 so that the mounting constitutes a one-way shearable bracket. Two rings of balls 48, 50 are located in axial grooves in the inside of member 24 and the outside of member 28, so that in event of accident, the force tending to telescope members 24, 28 is absorbed by the balls 48, 50 extending the grooves in the concentric members. In Fig. 5 (not shown) the balls are arranged to form a helix between members 24 and 28. The balls 48, 50 may be replaced by cylindrical or barrel shaped rollers and should be harder than the cylindrical members 24, 28 which are preferably of seam-welded, mandrel-drawn aluminiumkilled sheet steel.

This allows the local subscriber to hear the first word of the interruptor. He may regain priority by first remaining silent then speaking whereupon the increased signal at input 18-1 causes comparator 18 to function and reverse attenuation again.
