A store is patuented in which the initial instant of informa-
tion rc-trieved, pulse repetition frequency and intervals between
pulse groups can be varied within wide limits. One cold cathode tube
is used for storing each-pulse sequence; control of pulse storing
and retrieval is performed by a circuit with cold cathode tubes. The X
start of pulse sending is determined by the controlled ignition in-
stant of the tube which governs the pulse retrieval. The interval
between pulse groups which are sent out is det-ermined by a tifne
circuit, and pulse repetition frequency is determined by the frequen-
cy of the pulse generator. A-re-set tube is provided which returns
the store to its initial condition. The circuit is shown for the

summary)
The following theorem is due to Radon: Let D be a
6unded domain, and f(x, y) a continuous function defined
it, it. Assume that 'tile integral of f(x, y) vanishes along
Omry chord of f (x, y); then f (x, y) is identically 0. The
'111thor first of all points out that Radon's theorem follows
from the following result due to Cram& and Wold: Let 1
P(x, 3-) be a distribution function. Then
F(.v, y) is uniquely!
(lPtermined by tile values of its projections on all the strdight
lilles through the origin, i.e., by the values of the integrals.
