This lining up is a time consuming job. It is known to avoid this stringing up by placing the characters between individual. Isoiierrahmen clamped and the frames are stacked on top of each other.

The end of each stiites corresponds to the position of the sign to be attached to it. The waving can be done mechanically in a simple way * The electrodes in the form of characters are merged one after the other with the feed pins. In doing so, they will be with a Pliers held, which can also be connected to a pole of a welding apparatus. Of the The other pole is attached to a holder into which the contact pins of the tube socket are inserted are, at least one. Jaw of the pliers, with which the characters are held, must be thick that is equal to or less than the space between a characters, so that this cheek is between the fixed sign and the previously attached sign can be inserted.

So the signs will

Because the signs are only attached to one side of the tube, they must be made of mechanically relatively strong material. A chrome-wound iron alloy is preferably used for this : 009815/0961 BAD ORIGINAL

while the width of the material of the characters on the fastening side can be slightly larger than at the top,

The contact pins also exist

preferably made of a chrome-kickel iron alloy, because this can be easily merged with the glass. The advantage of welding the characters with the pins compared to soldering, for example, is, that for soldering the chromium-containing parts first have to be silver-plated at the points to be soldered, since chromium-containing materials cannot easily be soldered. The welding can against it can be done effortlessly.

Leakage currents between the pins, caused by the metal particles precipitating on the centering lath 19, are avoided. Such leakage currents cause several signs to light up at the same time. .

The pins 1 to 10 are made of a chrome nickel steel alloy Numbers 1 to 'OV welded on. Since the pins 1 to 10 themselves also consist of such ! alloy, offers welding no difficulties. The plate 20 is preferably made of a layer covered with a black layer Iron.

The pin 12 and / or 15 can

After welding the digits to the pins, it becomes a plate-shaped one Part 21 and a perforated part 22 arranged and existing anode cage around the electrode system blackened with the plate 20.

Then the piston 1S is fused to the base 17, after which the tube evacuated, provided with a suitable gas filling and removed.

The welding of the electrodes 1 to O ¹ with the pins 1 to 10 can preferably be done with a butt weld on top of the end of the pins. The advantage here is that the end face of the pins covered with a surface layer is always uncovered as a result of the cutting off, so that a local removal of the insulating layer is not necessary. For butt welding, for example, the character 6 'is first held in a pair of pliers connected to the welding pole. The base 17 is placed in a holder, whereby the pins are connected to the other welding pole. After the symbol 6 · is welded to the pin 6, the characters 5 ', 7 ⁽ , 4 ¹ , 8 «, 3 \ 9 \ 2 ·, 0 * and 1 ¹ are fused one after the other in the same way with the corresponding pins Welding tongs must therefore have jaws, at least one of which has a thickness that is smaller than

The pin 15 protrudes with the

The anode cage 21, 22 and

the plate 20 are completely blackened, so that they form a dark background and enable clear character recognition. The plate 20 also causes an even distribution of the anode field / so that no additional Än.odejizezug or anodes are required.

reaching mechanical strength so that they are only on one side, the underside _s need to be fixed. The width of the material of the characters can be somewhat larger on the underside than on the upper side, in order to increase the mechanical strength. For shock-proof arrangements, the characters can optionally be provided with a tongue at their upper end, which can be fastened in an insulating rod so that the characters form a rigid package. The insulating stick is only used to connect the characters to each other and not to fix and support the characters in the tube.

According to the invention, the

Electrodes can also be soldered or clamped be connected to the feeder pins.
