Abstract: 847,501. Protective cut-out arrangements. REYROLLE & CO. Ltd., A. Nov. 27, 1956, No. 36257/56. Class 38 (5). An intertripping arrangement comprising a pilot circuit K, a D.C. current source which is connected to the pilot circuit on the operation of a protective device at one end of a protected circuit, and a D.C. relay M controlling the tripping of a circuit-breaker at the other end of the protected circuit, has a low-pass filter P connected between the D.C. relay and the pilot circuit to prevent operation of the relay due to induced A.C. voltages and a voltage limiter R to prevent operation of the relay due to transient outputs from the filter. Fig. 1 shows an intertripping arrangement operative between the two ends of a protected transformer feeder A, A<SP>1</SP>, A<SP>2</SP> which is provided with a neutral-displacement protection relay B<SP>1</SP>, an earth fault protection relay B<SP>2</SP>, a Buckholtz relay B<SP>3</SP> and a transformer differential protection relay B<SP>4</SP> at one end of the feeder and an overcurrent relay B<SP>5</SP> and an earth fault relay B<SP>6</SP> at the other end of the feeder. These relays and manual switches B<SP>7</SP> ,  B<SP>8</SP> have contacts which when closed cause the tripping of the circuit-breaker E or E<SP>2</SP> and/or cause the operation of an intertripping relay K<SP>3</SP> or K<SP>4</SP>. When a relay K<SP>3</SP> or K<SP>4</SP> is energized, it closes contacts K<SP>1</SP> or K<SP>2</SP> to connect the pilot circuit to D.C. bus-bars and opens contacts K<SP>5</SP> or K<SP>6</SP> to disconnect the adjacent relay device L or L<SP>1</SP> which includes a D.C. trip relay M or M<SP>1</SP>. Each device L or L<SP>1</SP> may comprise an input resistance N, three T- section filters P<SP>1</SP>, P<SP>2</SP> of the constant-K type, an output resistance Q, the relay M and a rectifier R constituting the voltage limiter. In an alternative arrangement the low-pass filter includes one or more m-derived sections, Fig. 3 (not shown). Instead of the rectifier R, the voltage limiter may be constituted by parallel opposed rectifiers or by a non-linear resistor or by a neon discharge tube. Fig. 4 (not shown) illustrates a modification in which a single D.C. intertripping source is used in conjunction with a three-wire pilot circuit.

Abstract: 766,613. Semi-conductors. TELEFUNKEN GES. Dec. 20, 1954 [Dec. 19, 1953], No. 36683/54. Class 37. In a method of producing a PN junction the convex face of an impurity material is brought into contact with a semi-conductor. The impurity material may be applied in solid or liquid form. The Specification refers to known methods and states in this connection (i) in Fig. 2 a hemi-spherical impurity bead 1 has its flat face brought into contact with the semiconductor 2, (ii) in Fig. 3 impurity material 1 is applied under pressure to the semi-conductor 2, (iii) that although Fig. 3 is an improvement on Fig. 2 impurity pockets of gas, humidity and oxide are trapped at the joining surfaces 3 in both these Figures and these pockets mean an irregular PN junction or alloy face as at S in Fig. 2 and at 4 in Fig. 3. In the embodiment shown in Fig. 6 a piston 13 is moved in tube 12 so as to extrude a liquid indium drop 14. The tube 12 is then lowered into quartz oven 10 so that the underside or convex surface of the drop 14 makes contact as at 6, Fig. 4, with the surface of an N type germanium wafer 2. The drop 14 diffuses into the semi-conductor 2 in accordance with the curves 7, 8, 9 of Fig. 4 and gas pockets do not occur since all gas is displaced outwardly as the drop 14 spreads along the surface. The oven 10 is evacuated or hydrogen-filled and heated to 300‹ C., thus humidity and oxide pockets are also prevented. The method of Fig. 6 produces a smooth PN junction or alloy face as at 15 in Fig. 5. The invention has application in producing transistors as well as crystal diodes.
