Title: Indicator for an image displayed on the screen of a cathode ray tube
IPC: G01R13/30
Filed: 1945-06-29
Abstract: 594,382. Radiolocation; panoramic receivers. STANDARD TELEPHONES & CABLES, Ltd. June 29, 1945, No. 16654, Convention date, Aug. 9, 1944, [Class 40 (v)] [Also in Group XXXVI] In a circuit for indicatingthe position of a pulse relative to a fixed reference base by displaying it on the screen of a cathode-ray tube, the horizontal sweep wave comprises the combination of a sawtooth wave and a low amplitude rectangular wave, the timing of the leading edge of which may be varied. The high rate of sweep at the leading edge produces a gap in the sweep line which is used as a " strobe to measure the relation between a displayed pulse and the reference base. Fig. 1 (not shown) illustrates a panoramic receiver employing the invention to display and measure the frequency of received signals. The output from the receiver is applied to the Y-plates of a cathode-ray tube. A cathode-ray tube sweep voltage, Fig. 2a, synchronized with the receiver frequency sweep, is combined with an indexing voltage, Fig. 2b, to produce the resultant sweep voltage, Fig. 2c, which is applied to the X-plates of the cathode-ray tube. The leading edge 21 of the indexing voltage is adjustable in phase with reference to the sweep voltage so that a very rapid scan may be produced on any short length of the cathode-ray trade. This has the effect of producing a gap in the trace which when it is aligned with a pulse broadens the pulse and reduces it in brilliancy. The control on the indexing wave generator may be coupled to a meter scale so that the radio frequency corresponding to a pulse being indexed may be determined. A blocking- generator incorporated in the receiver causes a voltage to be applied to the control grid of the cathode-ray tube to blank the beam during the portions of the sweep wave shown as occurring below the broken line of Fig. 2c. The invention may also be employed in a pulse radar system for determining the distances of reflecting objects.

High tenacity viscose rayon filaments are produced by extruding viscose into an acid bath containing a small proportion of formaldehyde to form filaments, removing the filaments from the bath and stretching them, at a stretch ratio of 1À5 to 3À5 while not more than 20% regenerated, in an atmosphere of steam, preferably saturated and at a temperature between 90‹ and 110‹ C. The viscose is preferably made from pulp of D.P. over 600, the alkali cellulose made from the pulp is preferably not aged and the viscose is preferably spun without substantial ageing. It may contain 2 to 7% of cellulose and 2 to 9% NaOH. It may have a salt (NaCl) figure of 12 to 23, a gamma number of not less than 60, normally 73 to 90, or higher, and a ball fall viscosity of 30 to 400 seconds. The spinning bath normally contains 3 to 9% by weight of sulphuric acid and 4 to 18% of sodium sulphate, preferably about twice the sodium hydroxide content of the viscose. Zinc sulphate is preferably omitted or maintained at a concentration below about 0À2%. The formaldehyde content of the spinning bath is normally about 0À5 to 2À0%, preferably about 0À5 to 1À0%, its function being to retard regeneration. The temperature of the spinning bath will normally be about 20‹ to 35‹ C. and the residence time of the filaments in the bath normally about 1 to 4 seconds. Upon emerging from the steam stretching zone the filaments may be about 90% regenerated and may be immediately cut up into staple fibres. Regeneration may be completed by sluice acid (1% H 2 SO 4 ) used to wash the staple fibres out of the cutter.

A series-parallel decimal multiplier and divider has its product (or dividend) store in two parts I, II, read-out from, and back into, which is controlled by a trigger 8 itself controlled by the stepping pulse generators 2, 4 which read out the partial product (or remainder) and multiplicand (or divisor) respectively. Multiplication is by addition of multiplicand and partial product digits, in binarycoded form, which are read out to an adding mechanism, not shown. Initially 4 and 2 are in synchronism to energize the right-hand (lowest order) columns of 3, 1 and 8 is set to close switch 111 so that at each pulse on 12 a pair of corresponding digits are sent to the adder, the sum being returned to the upper row of 1. When 4 and 2 are stepped to the left-hand ends the trigger 8 will receive two pulses to leave it in its previous state, and the lowest order multiplier digit in 6 is counted down one. This action is repeated until this digit in 6 is reduced to zero, when a pulse is delivered to line 13 to step 2 and 6. In the following cycles the second to seventh digits of the partial product will be read with the first to sixth digits of the multiplicand since 8 will be switched to select the lower (more significant) row of 1 for the last digit (8 is switched back at the end of each cycle. In subsequent sets of cycles the trigger 8 will be operated successively earlier, the product thus being built up in the twelve decimal orders of 1. Division is by subtraction of the divisor in 3 from the dividend (partial remainder) in 1 with restoration and shift when the latter goes negative, the subtractions being counted to form the quotient digits in 5.
