Abstract: 844,072. High-frequency bridge networks. BRITISH BROADCASTING CORPORATION. Jan. 27, 1958 [Jan. 22, 1957], No. 2344/57. Class 40(8). The bridge circuit of Fig. 1 comprising impedances A, B, C, D, X, Y is realized by connecting together seven quarter-wavelength sections of transmission line in the configuration shown in Fig. 2, the six junctions being loaded by impedances A, B<SP>1</SP> = Z<SP>2</SP> 0 /B, C, D, X<SP>1</SP> = Z<SP>2</SP> 0 /X, Y<SP>1</SP> = Z<SP>2</SP> 0 /Y where Z 0  is the characteristic impedance of the transmission lines. The impedances B<SP>1</SP>, X<SP>1</SP>, Y<SP>1</SP> may be replaced by quarterwavelength sections of line terminated respectively in impedances B, X, Y. The circuit may be realized using coaxial lines, balanced twin lines or rectangular waveguides having series or parallel junctions. Where series junctions are used, inverse impedances (i.e. A<SP>1</SP> = Z<SP>2</SP> 0 /A &c.) are required at the junctions. In one form of the circuit (Fig. 6, not shown) the impedances X<SP>1</SP>, Y<SP>1</SP> may be provided by two transmitters using frequencies which differ only by a few per cent. The impedance A is that of a common aerial matched as closely as possible to the transmission lines. The impedance C is made equal to A. To obtain good power transfer between the transmitters and the aerial, B<SP>1</SP> and D are replaced by equal impedance elements which are large compared with A at all frequencies required to be transferred from the source X<SP>1</SP> to the aerial and small compared with A at all frequencies required to be transmitted from Y<SP>1</SP> to the aerial. These impedances may be of the form described in Specification 710,345. The bridge may also be balanced by making AC = B<SP>1</SP>D = Z<SP>2</SP> 0 .

Title: Transverse-flow fan
IPC: F04D17/04
Filed: 1962-01-23
Abstract: 984,697. Transverse-flow fans. ENGELHARD HANOVIA Inc. Jan. 23, 1962 [Jan. 26, 1961], No. 2530/62. Heading F1C. [Also in Division F4] A transverse-flow fan comprises a pair of elongated baffle assemblies, one at each side of the rotor to define a conduit through which air is conveyed, each baffle assembly including a pair of substantially flat strips movably joined together at one edge to form a hinge, and means for shifting each hinge selectively between two alternative positions, in one of which the hinge is close to the rotor surface and in other of which it is spaced away from the rotor, the remainder of each of the baffle assemblies being spaced away from the rotor in both positions of the hinge. By this means, the direction of flow through the fan can be reversed without reversing the direction of rotation of the rotor. In the fan shown in Figs. 5 and 6, two diametrically opposed baffles for guiding the flow through the rotor 10 respectively comprise flat strips 20, 22 hinged together on a hinge pin 56 and flat strips 24, 26 hinged together on a hinge pin 58. The pins 56, 58 are extended at each end to engage vertical slots 48, 50 in each casing side wall 42, 44. Pegs 68, 70, 72, 74 secured to the strips engage horizontal slots 60, 62, 64, 66. In the positions shown, in which pin 56 is close to the rotor periphery and pin 58 is remote from the rotor, the air flows from left to right of Fig. 5. To reverse the direction of flow, the pins 56, 58 are moved to the upper ends of the slots 48, 50, the hinged baffles then assuming positions similar to those that can be seen by inverting Fig. 5. To effect the reversal, there may be provided a bar 76 having a handle 82 and continuing into vertical arms 78, 80, each arm having bores receiving the pins 56, 58. The arms may be held frictionally in the two positions of adjustment by means of springs 90, 92. Since the inlet and outlet zones of the fan are separated from one another only by a narrow edge of the baffle positioned nearest the rotor periphery, with each space between adjacent rotor blades 12, when facing the baffle, communicating simultaneously with both zones, there is little tendency for the return of air from the outlet zone to the inlet zone through the region of the rotor obstructed by the baffle. This reduces turbulence and noise. In a transverse-flow fan described for explanatory purposes but not included within the scope of the invention, the two diametrically opposed baffles comprise radially disposed strips 14, 16, Fig. 1. Reversal of flow is obtained by radially moving the strips so that strip 16 is brought close to the periphery of the rotor 10 and the strip 14 is correspondingly withdrawn from the periphery. Or, the rotor 10 may be shifted to bring its periphery close to the strip 16. As a further alternative, both baffles may be rotated about an axis which is eccentric with respect to the rotor axis. The shift may be smaller or greater than 180 degrees to provide a corresponding change of direction of flow.

Abstract: 1499725 Automatic exchange systems JEUMONT-SCHNEIDER 22 Jan 1975 [25 Jan 1974] 2821/75 Heading H4K In an electronic time switching telephone system in which an operators line OP is connected to the switching network RC through a transformer TOP, and the transformer has a balancing network EOP which isolated the transmission path, containing encoder COP, from the reception path, containing decoder DOP, a modulator-demodulator MD-Fig. 4-including a variable gain amplifier A3 is provided and the amount of isolation between the reception and transmission paths provided by EOP is variable. If an operator wishes to break in on a conversation between subscribers X and Y and hold a triangular conversation with them it is necessary for the isolation between his reception and transmission channels to be removed. Hence during relevant time slots central control closes contact a, thereby shorting out the balancing network. However, during periods of operator surveillance it is required that a warning tone generator G be switched into a connection to inform the parties. It is shown in the Specification that the combination of speech and tone signals requires a level of attenuation different from that necessary for speech signals alone. Hence simultaneously with operation of switch a central control operates switch b, thereby altering the gain of amplifier A3. The balancing circuit may be included in a feedback path for the transmission path amplifier Al-Fig. 6 (not shown).
