Title: Tdm telecommunications exchange systems
IPC: H04J3/12
Filed: 1972-08-14
Abstract: 1404948 Automatic exchange systems SIEMENS AG 14 Aug 1972 [17 Aug 1971] 37752/72 Heading H4K In a TDM system in which signalling data relating to the speech channels occurs in a superframe, the data is stored in a memory for processing on a last look basis. In order to eliminate spurious responses, the data is classifled as being of "continuous" and "non- continuous" type and the processing is extended to take this into account by utilizing an additional memory. Thus, starting on the premise that a continuous data signal is being received in respect of a particular channel. (This signal may be the normal line-looped or seize condition for example) then both memories contain identical entries. If a change of data occurs, the last look memory content alters and after two superframes a genuine change is presumed. The content of the type memory is unaltered however unless after a further number of guarding superframes it is decided by a central processor that a new continuous characteristic is being received. In the normal case however, the data will eventually revert to the original format and after a last-look check there is a presumption that the intervening data change related to a non-continuous data signal. The central processor determines the length of this signal from the time that has elasped between the two successive outputs from the last-look memory. If however the data had changed but the change was not back to the original format, i.e. as the result of a prolonged but nevertheless spurious signal, then the corresponding output from the last look memory would be ignored. In the embodiment, incoming data in the 16th slot of each frame is inserted into a register ER. The data in each frame comprises 4 serial PCM bits in respect of each of two channels. Once every 15 frames i.e. a superframe, the data is presented in parallel to a last-look memory E,S1 and to two comparators V1, V2 which perform respectively a last-look check and a data characteristic check. Change are detected by a control unit Spr that acts as an interface logic for a not shown stored programme control. Genuine changes only are reported to the control. If the characteristic type stored in E,S2 is to be changed, the control unit permits the data presented by ER to be entered into E,S2.

An apparatus for removing dust from gases comprises a generally cylindrical casing 1, Fig. 1, provided with an inlet duct 26 for dustladen gas and with an outlet duct 25 for clean gas and divided by means of partitions 10, 11, 12 into a number of intercommunicating separating chambers, and a rotatable shaft 6 mounted axially of the casing and carrying annular members, e.g. discs 8 as shown, for imparting a rotary movement to the dustladen fluid as it flows from the inlet duct 26 towards the outlet duct .25, each chamber being provided with a deflector 31, Fig. 2, for directing towards an associated receptacle 20, 21 or 22 dust particles separated out by centrifugal force against the wall of the chamber. An electrostatic precipitator 27-30 is mounted in the inlet duct 26 through which the dust-laden gas is sucked by means of a fan 23 mounted on the shaft 6. The discs 8 are provided adjacent their periphery with holes 9 which on rotation of the discs generate sound waves in the dust-laden gas, causing agglomeration of the dust particles and hence facilitating centrifugal separation of these particles. Frustoconical deflectors 16, 17, 18 are associated with the partitions 10, 11, 12 for guiding the progressively de-dusted gas from one separating chamber to another towards the exhaust duct 25. The clean gas passes through guide vanes 24 before entering the fan 23. In a modification, Fig. 3, the annular members are in the form of two sets of coaxial rings 113, 114 supported by a disc 112 mounted on the rotary shaft 106. The rings of each set have progressively decreasing internal diameters as shown and, in addition to being provided with holes adjacent their periphery, have undulated edges. In addition to a centrifugal fan 115 the shaft 106 carries an axial fan 111, or a set of blades, in which separation between the gas and dust particles takes place. The flow path of the gas is from the inlet duct 118, through the fan 111, into a first chamber 134, outwardly through the spaces between the rings 113, inwardly through the spaces between the rings 114, into a second chamber 135, through the fan 115 and out through the outlet duct 119, separation between the dust particles and gas taking place within the fan 111 and in the spaces between the rings 113 and between the rings 114. The dust particles of different sizes separated out by centrifugal force pass through deflector openings 124 into different receptacles 125-128.

Title: Improvements in or relating to variable speed power transmission
IPC: F16H61/664
Filed: 1929-09-02
Abstract: 344,065. Variable speed gearing. HAYES, F. A., Middletown, New Jersey, U.S.A. Sept. 2, 1929, No. 39227/30. Convention date, May 7, 1929. Divided on 343,988. [Class 80 (ii).] Variable-speed gearing comprises torus discs and correlated sets of precessional rollers arranged for planetary revolution. In the Figure are shown twin sets of rollers 19, 50 supported upon spiders 25, 55, respectively, which are connected by a sleeve 13a, the rollers engaging torus surfaces connected in pairs. The end discs 10, 11 are keyed to driving-shaft 12 and the double middle disc 15 is loose and adapted to be held by a brake 72 to engage the drive, as described in Specification 344,063. The two sets necessarily precess in unison, and the load is divided between them, as described in Specification 344,064. Forward drives are taken from a ring 56 surrounding the second set of rollers 50 by a clutch drum 75 which slides on driven shaft 63. The axes of rocking of the rollers are inclined to the planes of the discs as described in Specification 344,061, so that the gearing is torque-responsive and control can be superposed by a slider 46 connected to the rollers 19 of the first set. The rollers 19 are supported between rockers 28 pivoted on the spider 25, as described in Specification 344,062, and the load on individual rollers is equalized by a connecting floating ring 35, as described in Specification 344,064. The rollers 50 are supported between rockers 54, and floating load-equalizing ring 56 surrounds the train. The control slider 46 acts by producing relative angular displacement between the spider 25 and ring 35. This is done by bowls 41 coacting with cams on elastic drums 39, 37 connected to the elements 25, 35, respectively. The driveengaging brake 72 and the speed control slider 46 may be operated by the automatic hydraulic control mechanism described in Specification 344,066, and the twin planetary gears may be caused to turn solid by a clutch 78 as described in Specification 343,988. Reversed driving is effected by moving a rod 68 manually, which connects disc 15 to the driven shaft 63 and causes the roller spiders 25, 55 to be arrested by brake 72, as described in Specifications 343,988 and 344,063.
