Title: Fluid switching circuits

Abstract: 1,017,990. Fluid logic circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 14, 1964 [Dec. 31, 1963], No. 50721/64. Heading G4B. [Also in Division G3] A fluid switching circuit is formed from a combination of two or more pure fluid switches. As shown, a matrix of monostable fluid switches is used. Each switch has an inlet passage 12 through which a signal X n  may be applied and control passages 18, 20 through which signals Ym, -Ym may be applied. If there is no flow in the passages 18, 20, a signal applied to the inlet 12 will pass through to an outlet 16. If one of the control passages 18, 20 is provided with a signal the stream from the inlet 12 will be switched into an outlet 28 or 26 respectively. This switched position is held only as long as the control signal is applied. Thus outlet 26 will provide the signal - Xn.Ym and outlet 28 the signal + XnÀYm. If no signal is present in the inlet 12, any stream in passages 18 or 20 will pass directly across into the opposing passage. A matrix of such switches will provide various logical combinations of the X and Y signals and Fig. 4 shows the signals produced by four switches. Fig. 5 shows part of a matrix formed from switches which will also operate on flows in the negative X direction, thus providing further logical combinations.

Abstract: 1,127,629. Semi-conductor devices. CSFCOMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 2 Dec., 1965 [3 Dec., 1964], No. 51308/65. Heading H1K. In a semi-conductor device such as a planar diode or transistor the surface at which the junction or junctions emerge is covered with insulant and a conducting layer on the insulated surface extends beyond the edge of this surface to contact an adjacent non-insulated surface. In this way the conducting layer is capacitatively coupled to one region of the device and directly connected to another so that, especially if the latter is the less heavily doped region, uncontrolled surface charge effects which would otherwise be caused by the presence of the insulant are avoided. In Fig. 2 (not shown), the device is a planar diode consisting of a P-type silicon wafer containing an N-type surface region and provided with a contact to this region. A layer of silicon dioxide covers the PN junction and surrounds the contact. Covering the oxide is a metallic layer, insulated from the contact but connected to the P-type body of the device by extending the metallic layer beyond the edge of the insulating layer to cover the peripheral face of the wafer. Fig. 3 (not shown), depicts an NPN planar transistor in which both the emitter and the base contacts extend through the oxide and are insulated from the surmounting metallic layer. Fig. 4 depicts a pair of interconnected transistors formed in a common P-type body. The oxide 28 protecting all the junctions is covered, as in the embodiments described above, with metal 34. The external base and emitter contacts 35 to 38 are insulated from this metal coating, and the connection 29 between the transistors is a thin metallic layer embedded in the oxide.

Abstract: 1,128,624. Size comparison. AUTOMATIC TELEPHONE & ELECTRIC CO Ltd. 23 Dec., 1965 [30 Dec., 1964], No. 52918/64. Heading G4A. In a digital data processing device in which the moduli of two signed data words A + B are compared for relative size, the state of a twostate switching device is controlled according to the algebraic sign of the resultant of the operations A + B and A-B. Thus, if the switching device is set for A+B positive, reset for A+B negative and has its state changed thereafter only if A-B is negative, then, if the switching device is finally in a set state A | # | B | and if the switching device is finally in a reset state | B |# | A | . The case in which | A | = ( B | is treated specially by monitoring for a zero result to the addition process (A and B of opposite sign) or subtraction process (A and B of same sign). An arrangement is shown in which the state of a bi-stable device TOF indicates the relative magnitude of the moduli of two binary words A and B which are added and subtracted by means not shown. The most significant bit of each word A and B indicates its sign and negative words are expressed in 2's complement form. The arrangement comprises a gating circuit including AND-gates GTS 1, GTS2, GS1, GS2, GR1, and GR2 and inverters ITS1 and ITS2. Gates GTS1 and 2 are controlled as indicated by signals indicating whether or not the signs of the words (AS and BS) _are equal and whether or not there is a carry (CS, CS) when the words are added or subtracted. These gates thus pass a signal only when the result of the addition or subtraction is positive. Signal SC is in its 1 state during the whole size comparison operation, signal A is 1 during the addition process and signal S is 1 during the subtraction step.
