Abstract: 849,014. Stencil switches. YOUNG, W. Dec. 22, 1958 [Sept. 20, 1957], No. 29691/57. Class 38 (5). [Also in Group XXXVIII] A switch having a path therethrough for the passage of a moving tape having adherent narrow strips thereon (Fig. 7, not shown) is operated by the increased thickness whenever such a strip passes. An insulating base a carries a contact c mounted on a blade b secured to the base a by a terminal d and adjustable by means of screw h. A metal part f, having a channel n therein forming a path for the strips on the tape, is fixed to base a by a terminal i and screws (Figs. 3 and 5, not shown) and thereby clamps a blade e carrying a contact g. A sprung pressure-plate p is carried by a part j, and bears against the tape to hold it against the part f. Thus contact g is depressed to engage contact c whenever a strip on the moving tape engages its back surface.

[Also in Division H3] A logic circuit suitable for use in an adding circuit comprises two transistors each connected with a third to form a long tail pair, the output voltage of the third transistor switching between two levels one of which is determined by saturation of the transistor. Fig. 7 shows a circuit for producing a " carry " signal by performing the logic operation (A.B) + (B.C) + (C.A) in which transistor sections J 13B  and J 14B  for negative signals perform the operation A.B at the common emitter connection and sections J 14A  and J 15B  and J 13A , J 15A  similarly perform the operations B.C and C.A. The multi-emitter transistor J 8  then performs the required OR operation, the " 1 " signal level being defined at the collector of J 8  by its saturation voltage and at the output of the succeeding emitter follower in addition by the voltage of the emitter junction of the emitter follower. The 0 level is defined by the voltage drop across transistor J 11  connected as a diode and the emitter base voltage of the emitter follower. In alternative AND, OR arrangements the multi emitter transistors are replaced by a single transistor and the diode connected transistor J 11  by a potentiometer formed by the collector resistor (R 2 , Fig. 1, not shown) and a resistor (R 3 ) from the collector to earth. The circuits described may be followed by inverters (Figs. 2, 5 and 8, not shown) comprising common emitter pairs with outputs derived from either or both collectors via a resistor circuit (R 6 , R 7 ) or via a transistor (J 12 ) strapped as a diode.
