Title: Telephone conference arrangement
IPC: H04M3/56
Filed: 1974-04-05
Abstract: 1454649 Conference circuits PLESSEY CO Ltd 3 April 1975 [5 April 1974] 15539/74 Heading H4K In a conference circuit for inter-connecting 2-wire access paths A-E, each access path is associated with circuitry comprising: (a) a hybrid transformer HA-HE; (b) a buffer amplifier AA-AE in the receive channel (R) of the 4-wire side of HA. The transmit channels (T) of the transformers HA-HE are connected to the input of a mixing amplifier MA which during a conference call supplies a composite signal to an input of each buffer amplifier AA-AE. Each buffer amplifier has a second input path, e.g. ASP, to which a signal derived from the T channel of the associated hybrid is applied. To set up a conference call a PAX subscriber dials the number appropriate to one of the conference circuit access paths, e.g. "102" relating to path A. Lamp LA is operated and the attendant responds by operating common key KM and key KMA, lifting his handset and obtaining the caller's conference requirements. The attendant then causes a holding condition to be placed on access path A, releases KMA and operates another access path key, e.g. KMB. He dials the PAX number of a desired conference party, and requests this party to hold pending completion of the conference connection. Similarly, subscribers may be connected to paths C-E. The conference proceeds by the attendant operating keys KCA-KCE to connect each two-wire path to a corresponding hybrid. A tie-line J may also be provided with conferencing facilities. The exchange may be an automatic SPC one, in which case the attendant functions are performed by central control.

Abstract: 850,011. Comparison pyrometers. BRITISH THOMSON-HOUSTON CO. Ltd. May 24, 1957 [May 18, 1956], No. 15593/56. Class 40(3). [Also in Groups XXXV and XL (c)] In a circuit, a transistor TI, Fig. 1, to the base of which an input 1 which is sufficient to drive it between saturation and cut-off is applied, applies a signal to the collector of a transistor T2, over a transformer TR, to produce in conjunction with an input 2 a direct current output across a resistor R, and a condenser C. The arrangement may give an output the magnitude of which is proportional to the amplitude of input 2 only when the two inputs are substantially in phase, or, may, if both transistors are driven hard between saturation and cut-off produce an output voltage indicating the phase displacement between two input voltage. The circuit, used as a phasesensitive comparator (descriminator) is shown in a self-balancing pyrometer Fig. 2 in which the phase of the output of a photocell to which radiations from a hot body HB and a lamp CL are applied through a shutter or chopper disc is compared with a reference wave in the comparator to produce a signal from a D.C. amplifier which is proportional to the difference between the two radiations whereby the radiation from the lamp is brought to that of the hot body, the voltage supplied to the lamp under these conditions indicating the temperature of the hot body.

[Class 4] A helicopter or gyroplane of the kind described in the parent Specification is modified to ensure the automatic reduction of the indidence of the blades to promote autorotation when the engine stops by utilizing the relative forward movement of the blades with respect to the hub. A blade spar 3, Fig. 5, pivoted about its own axis as well as about a vertical axis 51 and a horizontal axis at the hub, has a forwardly projecting arm 3a connected by a link 7 to a member 47, rotating with the hub as described in the parent Specification, but the angle between the arm 3<a> and link 7 is less than 90‹ so that forward movement about the pivot 51, as well as upward movement, results in a reduction of incidence of the blade. The member 47 is tiltable in any direction and vertically movable for controlling the pitch of the blades manually. Fig. 11 shows a modification wherein the arm 3<a> is replaced by a toothed quadrant 3<1>b which meshes with a pinion 7<1> on the horizontal axis 52<1> of a cardan joint having a vertical axis 51. The pinion meshes with a quadrant b which may be fixed to the hub, or, as shown, may be given a small oscillatory movement about the axis 51 by a link c having rollers d engaging an eccentric e. A modified arrangement of toothed quadrants and pinion is shown in Fig. 12 wherein the quadrant b has an arm b<1> connected by links M<2> to a member 47 rotating on a ball race about a ring 9<a> which can be raised and lowered by a link E and tilted in any direction by links F<1>, F". Instead of engaging the pinion 7<1> directly the quadrant 3<1b> may engage a quadrant carried by the pinion and of larger diameter. Where two superposed screws are used driven in opposite directions through the gearing shown in Fig. 14, manual adjustment of the pitch is provided for the lower screw only and during autorotation the lower screw drives the upper screw which is of relatively greater pitch. The upper screw blades have arms 3b connected to pivoted brackets 7b on the hub and the lower screw blades have arms 3<1a> connected by links 7 to a ring 47 movable vertically by a rack n. Alternatively the upper blades may have a fixed pitch. A freewheel t is provided between the engine and gears.
