Abstract: 761,060. Automatic voltage control systems. ROTAX, Ltd. June 4, 1954 [June 17, 1953], No. 16696/53. Class 38 (4). In a system in which an alternator with two sets of windings (or tapped windings) supplies an A.C. load, and, via a rectifier, a D.C. load, the alternator field being controlled by a carbon pile regulator in accordance with the D.C. load voltage; fluctuations of the A.C. load voltage are reduced by supplying the rectifier for the D.C. load through a saturable reactor having one control winding in series with the D.C. load, and optionally a second control winding energized in accordance with the current in the A.C. load circuit. Alternator winding a supplies the A.C. load, and winding b supplies the battery g via saturable reactor k and rectifier f. The alternator field c is supplied via a carbon pile regulator h from the output of the rectifier f and is regulated by coil i in accordance with the D.C. voltage. The reactor k has a reference winding n energized from the battery g opposed by a winding m carrying the D.C. load current so as to reduce the impedance as the current increases. A second control winding p, which opposes the winding m, is energized by the rectified output of a current transformer s in the A.C. load circuit. Additional primary windings t may also be connected in series with the generator windings b to prevent an excessive voltage drop in the A.C. circuit on load.

Title: Improvements in record cards or strips for accounting and statistical machines
IPC: G06K19/08
Filed: 1951-07-17
Abstract: 706,212. Statistical apparatus. COMPAGNIE DES MACHINES BULL. July 17, 1951 [July 18, 1950], No. 16974/51. Class 106 (1) A record card or strip is provided with rows of prepared areas at definite index locations any prepared area being convertable as required, by the addition of a chemical, into a data representing mark of different colour from that of the prepared areas. The record marks are thus made by a chemical combination of one chemical employed for the prepared areas, for example, a solution of one per cent of potassium ferrocyanide and another chemical, for example, a solution of one per cent of a ferric salt applied to those areas which are required to be converted into record marks, the colour of the chemical combination being different from the colour of the prepared areas. In this manner recording of data representing marks may be effected by hand with the exact location and shape of the marks being controlled by the prepared areas, which have previously been applied by machine, so that any misalignment of the hand applied mark is corrected. The prepared areas may be of the same colour as the card so that they are not visible, while the record marks are of a different colour so as to be visible when the second chemical is applied to the prepared areas. The card is sensed by a photoelectric arrangement which is actuated by record marks which are either distinctly darker, or lighter than, the record card surface. The record marks may be formed by means of a one per cent solution of cupric salt or a one per cent solution of a uranium salt in place of the solution of ferric salt referred to above. Alternatively, starch paste may be employed for forming the prepared areas and iodized water, prepared in the cold state, may then be used for forming the record marks.

Abstract: 663,944. Pencil holders. BOWLER PEN CO., Ltd., A. T., and BOWLER, A. T. July 25, 1949 [June 25, 1948], No. 17087/48. Class 146 (iii). In a propelling pencil of the type in which propelling and repelling mechanism, operated by the rotation of a cap at the top end of the pencil, is readily removable from the pencil barrel, a helical member 5 is secured in a sleeve 3 screwed into the barrel 1, such that the lower end of the member 5 is unsupported. A cap 8 carries a slotted guide member 6 carrying a slidable lead carrier 9 housing a slidable push rod having extensions 11. When the cap 8 is rotated, the extensions 11 engage convolutions of the member 5 so that a lead in the carrier 9 is projected or retracted with the carrier 9, the carrier 9 being eventually arrested during a projecting movement by a shoulder 2a, while the push rod expels the lead. The mechanism may be removed from the barrel by unscrewing the sleeve 3. Overwinding at the end of each projecting or retracting movement is prevented, since the extensions 11 of the push rod automatically disengage the member 5, re-engagement being effected by axial and rotational movement of the member 6 relative to the member 5 at the commencement of each movement. A bush 4 for retaining a clip 12 may be screwed on or formed integrally with the sleeve 3, or alternatively the sleeve 3 has a flange accommodated in a recess in the cap 8 for this purpose.
