Title: Speed change means
IPC: F16H1/32
Filed: 1973-12-27
Abstract: 1462061 Friction gearing R DAVIDSON JNR 27 Dec 1973 [27 Dec 1972] 52315/73 Heading F2Q In a speed reducing transmission in which a non-rotatable wobble plate 10 is caused to execute a circular wobbling motion by, e.g. a sleeve 19 formed integrally with an input pulley 21 and having an inclined face acting on the plate through a thrust bearing 23, and in which the reduced speed is imparted to a rotor 24 having an output element 27 in the form of a sprocket, gear, pulley, &c. by frictional engagement between a planar contact surface 12 of the plate and a convexly curved, annular face 25 of the rotor, the plate 10 is held against rotation by outwardly extending locating means 14 slidably engaging a body, base, &c. 17. As shown, the means 14 are ball jointed to rods 15 which are slidable in guides 16 on the base. The plate 10 has a ball-and-socket mounting (not shown) on a fixed shaft 20 on which the input and output members 21, 24 are rotatable, and a spring 28 loads the frictional drive surfaces, at least one of which is faced with a ring of friction material. The reduction ratio may be altered by substituting a sleeve 19 of different inclination or, it is stated, by axial adjustment of the shaft with the ball-and-socket mounting relatively to the plate 10 to alter the position of the wobble centre of the latter. A modification is referred to in which the wobble plate, universally mounted on a shaft which is rotatably and slidably mounted in the base by roller bearings, is flanked by a pair of sleeves with inclined faces keyed to the shaft. The output rotor has a peripheral flange in frictional contact with the wobble plate, and two lugs fixed to the base engage diametrically opposite bores in the wobble plate to hold the latter against rotation.

Title: Telephone connectors
IPC: H04M7/00
Filed: 1975-12-23
Abstract: 1528050 Telephone connector JEUMONTSCHNEIDER 23 Dec 1975 [31 Dec 1974] 52666/75 Heading H4K A telephone connector for interconnecting a subscriber, connected to a first automatic exchange having free trunk line equipment and free subscriber's line equipment, and a subscriber connected to a second automatic exchange capable of signalling at a plurality of frequencies to the connector and of interpreting changes of state thereof. The connector is used for direct inward dialling. The connector 2 includes, inter alia, terminating sets 5 and T, frequency detectors 7, 8, 9, a frequency generator 15, unhooking detectors 20, 21 and switching means, e.g. relays A, B, S and R controlled by logic gates 10-13, 22 and 23, for connecting the frequency generator 15 to set 5 and for connecting set T to the free subscriber's line equipment via transformer 17 and to the line free trunk line equipment via transformer 18. Operation.-When a subscriber connected to the second exchange 4 calls the extension of a subscriber connected to the first exchange 3, exchange 4 stores the called extension and emits a signal represented by frequencies f2+f3, which switches relay R to position 0 through gate 11, disconnecting transformer 18 and generator 15 and connecting set T to transformer 17. Contact R4 loops the free subscriber's line equipment; exchange 3 recognizes the looping and emits dialling tone which is detected by exchange 4 which emits the dialling pulses of the called extension by emitting frequencies f1+f3 modulated by on-off keying which operates relay A through gate 12 to connect the wanted subscriber. Exchange 3 then emits the ringing tone which exchange 4 detects and connects the calling subscriber to the connector 2. The operations of connector 2, when a subscriber of exchange 4 calls the operator of exchange 3 and when a subscriber of exchange 3 calls a subscriber of exchange 4, are also described. The signal generated by generator 15 and which is connected by exchange 4 via set 5, is used to signal when the operator of exchange 3 has lifted her handset, by disconnecting the output of 15 through B1, when she has been called by a subscriber of exchange 4: the same signal is used to indicate, when interrupted, that a subscriber connected to exchange 3 wants to call a subscriber on exchange 4. The connector may be used for long or short lines.

Abstract: 1530634 TASI systems; echo suppression INTERNATIONAL BUSINESS MACHINES CORP 29 Dec 1975 [20 March 1975] 52964/75 Headings H4M and H4K In a TASI system wherein a voice activity circuit is provided for giving a voice activity indication for each of a number of user terminals, means are coupled to the input and output circuits of the user terminals for determining when input activity is due to echo, said means causing said voice activity circuit to give an inactivity indication in response to the detection of echo. Adaptively companded # modulation is used for speech transmission. Duplex speech or data trunks are coupled via respective hybrids 19 to the inputs of a sampling unit 3 and the outputs of a distributer 5. Incoming speech samples pass, via an adaptive # modulation coder 11 which produces a one bit signal for each sample, to an input queue 15. Data passes via a data link 7 into the same queue. The coder 11 also supplies for each sample a companded digital integral representation corresponding to the analog telephone signal volume to a voice activity detector 21 which produces an output signal Vad= 1 if the sample volume exceeds a predetermined threshold level. An echo suppression logic 24 receives volume indication signals from both the coder and decoder for each two-way connection and produces an echo indication e= 1 if the signal from the decoder exceeds the coder signal. Function selection logic 23 produces a final voice activity bit vs from the vad and e signals which is binary 1 if e=0 and vad= 1 and binary 0 for all other combinations, this voice activity bit being stored in the input queue in association with the corresponding speech bit. When the condition vad = 1, e = 0 is detected the reception gain is reduced by 6 db. by subtracting 2 from the decode step-size count, i.e. in the case of original input activity. For incoming traffic from the digital switch arriving over trunks using TASI an activity bit is fed into the output queue. If this bit is binary 0, a noise signal is fed from a random noise generator LS in the corresponding time slot. It is stated that echo control is only used on long trunk connections and that TASI is not necessarily used on all trunks. For outgoing trunk calls subject to echo control but not subject to TASI, random noise is inserted into the input queue in the corresponding time slot for inactive channels.

Title: Washing Machine
IPC: D06F23/04
Filed: 1980-06-04
Abstract: An automatic washing machine of the fresh-water, vertical-axis type has a dynamic system which includes a single perforate wash basket 32 arranged to be driven continuously such that its central axis moves in an orbital path about another axis, rotation of the basket 32 about its central axis being restrained. Water is introduced into the basket 32, through a hollow annular fill ring 132 on the tub 36 and through a spout 30 to wash detergent from a cup 48, during orbital motion and that motion is effective to induce a continuous motion of the fabric article load for washing the load. Following washing, preferably the basket's central axis is aligned with the axis about which it was orbiting and is rotated about this axis to centrifugally remove water from the fabric load. The basket may be contoured to enhance toroidal and annular movement of the fabric load, e.g. by the provision of curved vanes 39, rings 53, ribs 58 and vanes 60. The machine transmission has an input shaft 203 driven by a reversible electric motor 20, and an output shaft 78 connected to the basket, the transmission having drive elements 74 for interconnecting the output shaft and the input shaft. The drive elements include eccentric drive members operative to shift the axis of the output shaft laterally from the axis of the input shaft when the input shaft is rotated in one direction, thereby driving the output shaft in an orbital path about the axis of the input shaft, and operative to substantially align the axes of the input and output shafts when the input shaft is rotated in the other direction, thereby rotating the output shaft. A one-way clutch and a disc brake assembly, including an off- center coupling, cooperate with the drive elements to restrain the basket from rotating when in the orbit mode or when the motor is deenergized, and to rotationally drive the basket when in the water extraction mode. <IMAGE>
