Abstract: 416,151. Calculating -- apparatus. CASTELLS, P., 606, Calle Cortes, Barcelona, Spain. June 13, 1933, No. 16851. Convention date, June 18, 1932. [Class 106 (i).] Apparatus for the mechanical solution of systems of linear equations comprises a plurality of sets of mechanisms arranged to give a summation of displacements each of which displacements represents the combined effect of a displacement in accordance with the unknown and its coefficient. As shown in Fig. 1 the unknowns x, y, and z are represented by the angular displacements of crank arms OP, OQ, and OR and the coefficients a, b, and c are the distances of the cursors A, B, and C from the axis O of the cranks. The terms ax, by, and cz are represented by the linear displacements of pulleys D, E, and F, the sum of such movements being obtained by a band passing under these pulleys and over fixed pulleys as shown in Fig. 3 to produce a movement at the point K representing the independent term in the equation. The displacements relating to the other equations are obtained in a similar manner the groups of crank arms corresponding to each unknown being mounted on one and the same axis as shown in Fig. 2. Instead of a band the displacements may be summed up by a system of racks associated with fixed and movable pinions.
Patent GB-169556-A (GB)
Abstract: 169,556. Krause, A. C. July 15, 1920. Factory and like time-recorders, card-type.- Consists in manually controlled means for adjusting the position of the individual record card or sheet with respect to the time printing wheels. The card or sheet is inserted through a slot 9, which extends across the machine and is prolonged at 10 along the side walls, and is supported on a table 4 in proper relation to the type-wheels 5, inking-ribbon 6, and printing-hammer 7. The distance to which the card can be pushed into the slot 9 is regulated by a card-stop 11 which rests on the table 4 and is guid d thereon by lugs 18 projecting into slots 19, 20 in the table and by a tail-bar 12 movable in a guide 13 formed in an extension of the table. A spring 15 fixed to a bridge-piece 16 holds the card-stop in contact with the table. A tooth 21 on the underside of the card-stop 11 projects through a slot 22 in the table and can be adjusted to engage one of a series of notches 23 in the edge of a sliding bar 24 extending out through the front of the casing. The bar 24 is guided to move parallel to the direction of movement of the card-stop by means of a pin 26 engaging a slot 27 therein and a pivoted latch 29 that can be moved to allow the bar 24 to be turned about the pin 26 for the purpose of effecting the adjustment of the cardstop. The extent to which the bar 24 and card-stop can be moved together is governed by the length of the slot 27 and by a pin 30 on the bar movable between a fixed stop 31 and an adjustable stop 32. A pointer on the bar cooperates with marks on the table extension 28 to indicate the position of the bar and stop. A long notch 37 is provided at the end of the series 23 so that when the tooth 21 is in engagement therewith the bar 24 can be moved without causing a corresponding movement of the cardstop. While the card-stop 11 determines the column in which the record is effected a fixed pointer 38 on the casing enables the required row or line to be selected. To lock the bar 24 or to limit its movement during certain periods a locking pin operated automatically by the clockwork may be provided and so arranged as to pass through a hole 39 in the table and to engage a notch 40 in the bar. The bar may also be coupled to a multi-colour inking-ribbon so that in certain positions the time-indications will be printed in the selected colour.
