Title: Bistable circuits
IPC: H03K3/356
Filed: 1973-01-25
Abstract: 1414402 FET bistable circuits HITACHI Ltd 25 Jan 1973 [28 Jan 1972] 3925/73 Heading H3T A bistable circuit includes a first load T6 connected to a first FET T1 a second load T8 connected to a series connected second and third FETs T2, T3 and a fourth FET T4 connected as a transfer gate between an input and the input of FET T1. The output of the FET T1 is connected to an input of one of FET T2 or FET T3, the connection point between the second load T8 and the second FET T2 or the third FET T3 is directly connected for feedback to the input of FET T1, a first pulse signal #X is applied to the input of FET T4 and a second pulse signal #X different in phase from the first pulse signal is applied to the input of the other one of FET T2 or FET T3. As shown the FETs are of P channel type and information (V in Fig. 3, not shown) is read in from input FET T10 by a clock control signal #X which causes T4 to conduct so that the input is stored at a (as Va) in the feedback circuit. The potential at b is the inverse (Vb) of that at a and the output (V OUT ) is delayed with respect to the potential (Vb) by the clock signal #2 which makes T5 conduct. In a modification (Fig. 4, not shown) the load FETs T9 and T6 are driven by clock pulse signal #X and a further FET load (T7) is connected in parallel with T6 and FETs (T7) and T8 are driven from clock pulse signal #2 so as to lower the power consumption. The output may be taken from the output electrode of T2 through T5 instead of from b. Inverter circuits may be connected between the output of T4 and a or between the output of T1 at b and the input of T5.

IPC: G09F13/14
Filed: 1927-02-15
Abstract: 294,723. Beuttell, A. W. Feb. 15,1927. Signs.-Uniform illumination of an advertisement or other display is obtained by the use of a concave transparent window of sheet glass or the like adapted to receive light rays at a large angle of incidence and reflect them on to the display, thus balancing the loss in intensity of illumination as the distance from the source increases, by the higher percentage of reflection as the angle of incidence increases with the distance from the source. Fig. 2 shows a concave transparent viewing window a reflecting light from the reflector-shaded lamp c towards the screen b which may be of reflecting or diffusing material and may carry or serve as a background to figures, letters, pictures or objects to be displayed, such objects &c. being either reflecting or diffusing as desirable. In some cases parts of the inner surface of the window a may be occupied by light-diffusing or translucent letters &c. out of line with those on the screen b, enabling both sets to be viewed at the same time, or these letters may be silhouetted against a. plain light-diffusing screen b. The reflector-window a may be partly plane and partly concave, the concave portion reflecting on to the part of the display remote from the source. Where the display is to be viewed from both sides two opposed concave reflector-windows may be employed, each carrying letters &c. on their inner surfaces, with or without objects arranged intermediately for display, and also with or without an opaque screen arranged between them to function similarly to the screen b, Fig. 2. In another construction the reflector plates resemble a bi-convex .[ane. the lamp being placed between them on the principal axis and shaded from direct vision. The screens may be open at the ends or may be closed by mirrors or plates carrying letters, thus forming a box casing.

Abstract: 396,802. Transformers ; mercury-arc rectifiers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and READ, J. C., The Gable House, Bilton, Rugby. Feb. 12, 1932, No. 4250. [Class 38 (ii).] To enable the transformer normally used for supporting power current to a mercury arc rectifier to supply current at low voltage during the " bakeout " process for removing occluded gases, the secondary phase windings are changed to a series connection that would, with the same transformation ratio for each phase, produce no resultant voltage, and the tap connections are then changed so as to produce slightly unequal transformation ratios for the different phases thus producing a low resultant voltage for supplying " bakeout " current to the anodes. Fig. 2 indicates how the standard doublestar connection shown in Fig. 1 is changed to supply current at low voltage between the points 9, 10 and 11, 12 to two anodes. Fig. 6 indicates how the standard triple-star connection of secondary windings shown in Fig. 5 is changed to supply low-voltage current to two anodes, the tap connections on the primary side being changed as in the previous example. Where a connection involving two groups of secondary phases energized by separate primary groups is employed, corresponding phases of the secondary groups are connected in opposition and the tap connections are adjusted to give slightly different ratios so as to provide a low resultant voltage.
