Abstract: 829,297. Electron beam deflecting apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 2, 1956 [March 5, 1955], No. 6617 /56. Drawings to Specification. Class 39(1). To maintain one dimension of an initially circular beam constant during deflection in two directions, use is made of the deflecting system described in Specification 790,427, which in that Specification is employed in conjunction with an initially elongated beam. Thus in the scanning direction which is perpendicular to the constant dimension the meridional image surface coincides with the screen, while in the other direction the sagittal image surface coincides with the screen. The dimension perpendicular to the constant dimension is allowed to vary instead of being made small as previously. Correction of coma is unimportant. The deflecting coils may be wedge-shaped saddle coils or two sets of toroidally wound coils with variable spacing of the coils around the toroid in the two sets, as described in Specification 790,427. In its application to colour-television strip screens the constant dimension may be perpendicular or parallel to the scanning direction according to whether the strips are scanned longitudinally or transversely. Specifications 640,153 and 672,624 also are referred to.

Abstract: 848,953. Digital electric calculating-apparatus. KIENZLE APPARATE G.m.b.H. Feb. 28, 1957 [Feb. 28, 1956], No. 6736/57. Class 106 (1). An electric computer has an accumulator consisting of a shifting register connected in a closed ring circuit. As described, the accumulator comprises sixteen decimal registers 40 ... 190 each consisting of ten saturable magnetic cores such as 401 ... 49, Fig. 2, one of which is magnetized in a sense opposite to the other nine. Each time a shift pulse 221 occurs on windings a this marking condition is stepped on to the next core in a known manner. The windings a are connected in series through all the registers 40 ... 90 so that when ten shifting pulses are supplied by a generator 75 any decimal quantity previously registered is shifted by one decimal denomination. Entry of partial products. Two of the decimal registers 40 and 50 have additional shift windings a2 fed by pulse generators 20 and 30 at the output of a multiplier 10. The right-hand and left-hand digits of each partial product emanating from the multiplier 10 are represented by equivalent numbers of pulses on generator output lines 21 and 31, respectively, and cause the marking condition in each of the registers 40 and 50 to step on by corresponding amounts. Switches 53 and 15 are set in the right-hand positions during this period and therefore when a shifting pulse steps on the marking condition from a " 9 " core this condition is transferred both to a carry storage core 59 or 67 and also back to the zero core of that register. At the termination of the entry period the switches 53 and 15 are changed to the left-hand position and ten shifting pulses are supplied by the generator 75 to all the registers as described above. Switches 53 and 15 are then changed back again and a pulse from a further generator 65 clears the "carry" storage cores 59, 67 to enter additional pulses via the generators 20 and 30 if carries have been registered. These additional pulses immediately precede the pulses representing the next partial product. The sequence of events is controlled by a commutator 85 which may also consist of a ring of magnetic cores. The switches 53 and 15 would normally be electronic devices. Other arithmetic processes such as division and subtraction could be carried out, and other bases of notation such as binary could be used. Results could be printed out after printing members have been set by output signals from each decade register occurring during the shifting process.

Transfer mechanism; registering difference of positive and negative actuations.-Relates to indicating-apparatus for use in signalling, adapted to indicate angles from zero to 180 degrees port or starboard, " deflections " from zero to 49 knots right or left, or a change of range from zero to a maximum opening and closing, of the kind described in Specifications 29422/04 and 16256/06, and involving counting-apparatus provided with transfer mechanism whereby indications can be shown on either side of zero, and consists in the provision of one set of drums only, the two sets of indications being shown on each drum. A shutter-like device formed with apertures, which may also act as a numeral-bearing element, is provided to mask one set of indications and uncover the other as the zero point is passed through. An intermittingly-driven shaft B has secured thereon a drum C which acts as the lowest denomination drum, and is marked with fractional indications as shown in Fig. 8. Loosely mounted on the same shaft are drums D, E bearing two sets of indications, Fig. 9, and the reading aperture shutter F bearing numeral indications as shown in Fig. 2. Connexion between the drum C and the remaining members is effected by double teeth G on the drums and transfer pinions H, K, the arrangement being such that the first movement of the drum C from the neutral position shown in Figs. 2, 3 and 4 in either direction causes the drums D, E to move through a space equal to one graduation and as all the transfer teeth are in engagement, this movement is transmitted to the shutter, which takes up a position to show either the plus, or minus graduations through apertures L<1> or L at a slot in the casing. Subsequent movements cause the drums to move through a space occupied by two indications. In the form shown, the indications are repeated on the fraction drum C and two sets of transfer teeth G are provided, but more or less than this number may be employed. In a modification the drums are replaced by disks or endless bands may be employed.
