Title: Improvements in or relating to electrical circuits
IPC: H03K5/1532
Filed: 1960-08-15
Abstract: 939,809. Magnetic recording circuits. SIEMENS & HALSKE A.G. Aug. 15, 1960 [Aug. 14, 1959], No. 28177/60. Class 40 (2). [Also in Groups XIX, XL (b) and XL (c)] A circuit for producing a response to input pulses which may be of variable amplitude, for example pulses read from a magnetic tape, at the instant at which their amplitude is at its maximum, comprises means for differentiating the input pulses and means for producing a response at the instant at which the polarity of the differentiated signal changes, said latter means being conditioned to respond only during the intervals at which input signals are applied to the circuit by a gating circuit controlled by the application of the input pulses thereto. Input pulses S1, S2 are applied at E to a transistor amplifier T1 through a differentiating circuit C1, R1 so that differentiated signals S1<1>, S2<11> are applied from transistor T1 to the input of a Multiar circuit comprising a transistor T2 with feed-back through a transformer Tr from its collector to its base, the diode D permitting the feed-back to be effective only when the differentiated signal goes negative so that the circuit is triggered to produce a response at the output A at the instant at which the differentiated signal changes polarity from positive to negative. To prevent the operation of the circuit by spurious signals, a monostable-state circuit comprising transistors T3, T4 operates as a threshold circuit controlled by the input signals, the level at which the circuit operates being determined by the choice of resistors R4, R5. An input pulse switches the monostable circuit which provides an output to render transistor T5 conducting, thus completing the circuit from the source UB through the emitter-collector circuit of transistor T2 to earth.

Abstract: 480,123. Filters for lenticular Rims. OPTICOLOR AKT.-GES. Oct. 19, 1936, No. 28416. Convention date, Oct. 17, 1935. Addition to 454,357. [Class 98 (ii)] The colour filter described in the parent Specification which comprises strips of three colours cyclically interchanged in two directions at right-angles, is used in conjunction with films having cylindrical lenticles by arranging the diagonal strips containing the same colour parallel to the lenticles so that the sum of the areas of different colours in all strips extending in two directions at right-angles to each other and inclined to the lenticles, combine to give white. Fig. 3 shows such a filter having blue, green, and red elements B, G, R, the broken lines indicating the direction of the lenticles on the film. The areas Z which project into strips of different colour may be rendered opaque as in Fig. 4. If untreated, however, they combine to give the effect of white interspaces, or may be rendered colourless to provide white interspaces. Alternatively, they may be coloured in the same colour as the strips into which they project. They may also be replaced by enlarged impermeable parts having openings in the form of regular hexagons or of circles as in Fig. 5.

Title: Stabilising device preventing overturning when tipping body vehicles are unloaded
IPC: B61D9/02
Filed: 1950-11-28
Abstract: 679,898. Tipping vehicles. SOC. SOVELVEHICULES ELECTRIQUES INDUSTRIELS. Nov. 28, 1950 [July 27, 1950], No. 29075/50. Class 108(i) A device for preventing overturning of a tipping body 6, Fig. 1, comprises a pivoted shoe 1 moved by a hydraulic jack 4 against a spring 5 to contact the ground. A pump 9 drawing from a reservoir 10 simultaneously supplies the shoe jack 4 and the tipping jack 8 through a valve 11. In operation, the jack 4 is first moved to lower the shoe and then the heavier loaded jack 8 is operated to tip the body 6 and allow the rod 14 and ball 12 to rise. When the reaction of the shoe is increased by the shifting centre of gravity of the load the seated ball 12 prevents the passage of oil between the jack 4 and the now lightly loaded jack 8. The body 6 may be returned by opening the valve 16, causing the rod 14 to move down and unseat the ball 12 and the jack 4 to empty, which permits the spring 5 to raise the shoe 1. In Fig. 2, the body is raised by a cable hoist 18 which also drives the pump 21. The movement of the body allows the balls 24 and 25 to rise to operate the jack 4 and lower the shoe. The pump 21 may be provided with a byepass valve to evacuate the surplus oil once the jack is operated. After tipping, the return of the body 6 unseats the ball 24 to move the jack and raise the shoe. In a modification a vertically moving instead of a pivoting shoe is used.
