Abstract
Abstract In an oscillograph having a magic-band type electric beam tuning indicator tube and mechanically driven dissecting means passing thereover adapted to change the length of the displayed light band of the indicator tube as a function of time, the dissecting means comprises a slotted member having equally spaced slots extending in the direction of change in length of the light band, the slots being narrow relative to the width of the light bands, and the slotted member being adapted to cause the slots to sweep across said width. The slotted member is preferably a hollow slotted cylinder of a size to fit over and rotate about the indicator tube, and the spacing between the slots is preferably at least equal to the width of the light band.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
100 words
In an oscillograph having a magic-band type electron-beam tuning indicator tube and mechanically driven dissecting means passing thereover and adapted to change the length of the displayed light band of said indicator tube as a function of time, the improvement comprising using as said dissecting means a slotted member having equally spaced slots extending in the direction of change in length of said light band, said slots being narrow relative to the width of said light band transversely of the direction of change in length thereof, said slotted member being adapted to cause said slots to sweep across said width.
Claim 2
Dependent Claim
100 words
In an oscillograph having a magic-band type electron-beam tuning indicator tube and mechanically driven dissecting means passing thereover and adapted to change the length of the displayed light band of said indicator tube as a function of time, the improvement comprising using as said dissecting means a slotted member having equally spaced slots extending in the direction of change in length of said light band, said slots being narrow relative to the width of said light band transversely of the direction of change in length thereof, said slotted member being adapted to cause said slots to sweep across said width.
Claim 3
Dependent Claim
24 words
The oscillograph as claimed in claim 1, wherein the spacing of said slots is at least equal to said width of said light band.
Claim 4
Dependent Claim
19 words
The oscillograph as claimed in claim 1, wherein said slotted member comprises a hollow cylinder accommodating said indicator tube.
Claim 5
Dependent Claim
122 words
The oscillograph as claimed in claim 1 for showing the oscillograms of two voltages, wherein said slotted member has two rows of equally spaced slots which are arranged so that one row of the slots passes along one part of the two-part light band of the tube and that the slots of the two rows are relatively offset by half the spacing between adjacent slots and that the spacing of the slots is substantially equal to twice said width, and comprising in addition means for supplying said electron-beam tuning indicator tube with two voltages to be illustrated in such an alternating rhythm that the oscillograms of the voltages are separately registered by the upper and the lower portions of said light band.
Claim 6
Dependent Claim
24 words
The oscillograph as claimed in claim 1, wherein in operation a single slot of said slotted member reciprocates in front of said light band.
Claim 7
Dependent Claim
22 words
The oscillograph as claimed in claim 5, wherein said slotted member is brought into a tOrsional vibration by means of a spring.
Claim 8
Dependent Claim
28 words
The oscillograph as claimed in claim 5, wherein said slotted member is brought into a torsional vibration by means of a rotating shaft and an eccentric coupled therewith.
Claim 9
Dependent Claim
82 words
The oscillograph as claimed in claim 1, wherein coupling means are connected to said slotted member and are adapted for coupling rotatable structural parts of arrangements which are to be oscillographically tested, said coupling means including a gear having such a transmission ratio that such structural parts carry out one or more revolutions or rotate through an angle, the whole-number multiple of which is a complete revolution, while said slots continue to move through the distance of the spacing of adjacent slots.
Claim 10
Dependent Claim
53 words
The oscillograph as claimed in claim 1, wherein said slotted member is driven by a synchronous motor having an interposed toothed-wheel gear, the casing of said synchronous motor and the degree of rotation being indicated on a dial, preferably directly in the form of the phase angle of two voltages to be compared.
Claim 11
Dependent Claim
25 words
The oscillograph as claimed in claim 9, wherein said dial and the pointer thereof are relatively adjustable without any simultaneous rotation of said synchronous motor.
