Title: An improved semi-conductor arrangement comprising a cathode, an anode and a control electrode
IPC: B65G25/08
Filed: 1954-03-24
Abstract: 764,489. Semi-conductor devices. SIEMENS & HALSKE AKT.-GES. March 24, 1954 [March 25, 1953; Nov. 17, 1953], No. 8645/54. Class 37. A semi-conductor amplifier comprises a first thin zone 3<SP>1</SP> of one conductivity type lying between two zones 2<SP>1</SP>, 4<SP>1</SP> of the opposite conductivity type, a cathode 2 and an anode 4 connection to each of the two zones respectively, and a control electrode 3 connected to the first zone, both PN junctions being reverse biased to such a magnitude that the two resulting space charge regions overlap. A continuous space charge region thus lies between anode and cathode and current between these electrodes due to carriers injected from the cathode is controlled by varying the potential of the control electrode. The central zone may be wedge-shaped, or, as shown in Fig. 7, thinner in its central region, and the impurity concentration may vary along the anode-cathode path, being greatest in the region adjoining the cathode. The region adjoining the control electrode may also be of increased impurity concentration. The semi-conductor material may consist of germanium or silicon, or of a compound of elements of the third and fifth, or of the second and sixth groups of the Periodic system. Current between anode and cathode comprises carriers which overcome or penetrate the .potential barrier by thermal energy or tunnel effect, and carriers which provide Zener current. The biasing and impurity distribution, and possibly the operating temperatures, is arranged so that the major part of the anode current is provided by those carriers which overcome the potential barrier, and are thus subject to control by the potential of the control electrode. The shape of the potential barrier may also be controlled to increase or decrease the proportion of carriers which overcome the barrier by tunnel effect rather than thermally, so that the arrangement may be either less or more sensitive to temperature respectively, as desired. The arrangement is distinguished from, and has a lower input capacitance than, the analogue transistor in which control is exercised by varying the thickness of part of the anode-cathode path, which lies between two variable space-charge regions.

Title: Improvements in or relating to valves with a passage of annular cross-section
IPC: F16K43/00
Filed: 1949-03-31
Abstract: 684,397. Valves. CULAUD, A., and ATELIERS DES CHARMILIES SOC. ANON. March 31, 1949 [June 4, 1948], No. 8765/49. Class 135. A valve, e.g., for an autoclave, comprises a closure member 4 having a main seating insert 14 adapted to coact with a main seat 18 in the body 1, and an auxiliary seat 22 in the body adapted to be moved to coact with an auxiliary seating surface 23 on the valve member when it is desired to remove the seats 14, 18 for attention. The seat 23 forms part of a piston 17 and a chamber 26 above the piston is connected to the inlet side of the valve or to the atmosphere under the control of a cock 27, the chamber 24 beneath the piston being open to atmosphere through a passage 25. The valve is controlled by a pilot valve 55 which balances the main valve closure member and is actuated by a servo piston 8 supplied with a control fluid through a pipe 9 under the control of a valve (not shown). Inlet pressure acts through a pipe 13 on a small piston 10 to seat the member 4 when the pipe 9 is connected to exhaust. The pilot valve has main seats 49, 52 and auxiliary seats 48, 54, the seat 52 being attached to a piston 61 urged to engage seat 49 by inlet pressure acting through a passage 59. When seat 23 is actuated to engage seat 22, the passage 59 becomes open to the valve outlet hence the auxiliary seats of the pilot valve engage each other and the seats 14 and 18, 49 and 52 may be removed through the outlet after removing a pipe section C. In another arrangement, a pilot valve 62, Fig. 2, is arranged in a conduit 63 which by-passes the main valve and both the main and auxiliary seats 18, 23, respectively of the body are attached to pistons 45, 17, and are movable into and out of contact with the respective seats on the closure member. The closing movement of the closure member is limited by a stop formed by a washer 32a on piston 10, thus permitting the main and auxiliary seats to be moved independently of the force which urges the closure member in the closing direction. In a modification, the servo piston is located on the outlet side of the closure member, and only the main seat in the body is movable, being actuated either by screws accessible from outside the valve or by inlet pressure. In another arrangement, the closure member slides on vanes connected to the walls of the body and supports a cylinder for the servo piston.

Title: Doppler Radar
IPC: G01S13/60
Filed: 1968-02-22
Abstract: 1,152,812. Pulse Doppler radar. GENERAL PRECISION SYSTEMS Inc. 22 Feb., 1968 [1 May, 1967], No. 8777/68. Heading H4D. A Doppler radar in which a pulsed microwave carrier is radiated from an aircraft on at least one forward 11 and one rear beam 12 has a receiving aerial system which mixes the echoes resulting from each beam to produce a pair of signals e 1 , e 2  which are identical except for a 90 degrees phase difference, detectors 34, 35, and a circuit fed with the detector outputs to produce an output signal having a frequency that, according to which of the demodulated signals leads in phase, is respectively greater or less than a reference frequency by an amount representing the Doppler shift. The sense of the velocity vector (important for helicopters) is thereby obtained in a pulse non-coherent radar. Aerial 10<SP>1</SP> comprises two slotted waveguide arrays, one (37, Fig. 4, not shown) transmitting beams 11, 12 but both receiving the echo energy; the waveguides are longitudinally displaced to afford a 90 degrees lag of one relative to the other on reception. Each detector 34, 35 may be a square-law device, the respective output signals giving Doppler information in the form where V f  and V a  represent the Doppler frequency shifts in the echoes from beams 11, 12 respectively. Signals e<SP>1</SP> 1 , e<SP>1</SP> 2  are multiplied with a constant angular frequency P signal from a generator 42, one path including a 90 degrees phase shifter 43. The output from differencing circuit 44 is of the form thereby giving the sense of the velocity vector since (V f  - V a ) is positive for forward motion but negative for rearward motion. A frequency tracker 45 is added since there will be a spectrum of, rather than a single, frequency; the frequency tracker may be of known kind and is outlined with reference to Fig. 5 (not shown). Modifications.-In an alternative receiving aerial arrangement a pair of parabolic dish aerials are joined by a common cable having two output junctions separated by 90 degrees in phase, Fig. 6 (not shown); or a 90 degrees phase shifter may be inserted into the feed to one detector, Fig. 7 (not shown).

Title: Improvements in or relating to circuit arrangements for relay line-selectors in telecommunication installations
IPC: H01H67/22
Filed: 1957-03-18
Abstract: 806,826. Automatic exchange systems. SIEMENS & HALSKE A.G. March 18, 1957 [March 17, 1956], No. 8892/57. Class 40 (4). In a relay selector employed in a 100-line exchange the individual coupling relays are connected between two sets of ten marking wires, one wire out of each set being marked by the relay chains that register the tens and units digits. The selector is taken into use by the operation of relay X and when connection is made to the calling line, relay A energizes followed by C, Y. Impulses are repeated by the discharge of a condenser Kol and the tens digit is registered on the relay chain Z1-Z5, the auxiliary relay ZK being energized with Z1 at the first impulse and being released when Z1 energizes a second time at the sixth impulse. Dialling relay V is operative during the impulse train and then falls back to release Y which transfers the impulse circuit to a similar relay chain E1-E5, EK for the registration of the units digit. The relapse of V now connects up X which was previously short-circuited and a circuit is made for the relevant coupling relay. If, for example, the number dialled is 12, markings are applied to wires za1, ea2 and relay K12 energizes in series with Z and common relay GH. In order to prevent simultaneous tests, a distributer PV makes connection with each relay selector in succession, and when it connects with the selector shown the test circuit through relay P is completed provided the wanted line is free. Relay P locks in series with line and cut-off relays R12, T12 and disconnects X, Z, GH and the register relays. Relay Z is maintained temporarily in the discharge circuit of condenser Ko1 and during its release time the called line receives a preliminary burst of ring- ing current which is then replaced by the normal interrupted ringing current. Relay Y energizes upon reply, connecting up X to complete the connection and reoperating V. If the called party hangs up first, relay C is released by shortcircuiting. If the wanted line is busy, P does not respond and C is not held, so that the selector is released and a busy signal is given.
