Title: Treating of fibrous materials
IPC: D01H4/08
Filed: 1967-02-04
Abstract: In break-spinning, the fibres are doffed from the surface of a separating-member by an edge of the rotary spinning-chamber. In Fig. 1, the separating -member comprises a rotating roller 2 with needles on its surface which is supplied with sliver fed through a funnel 7 by a rotating roller 5.The rollers and the funnel are in a block 9, the clearance between the roller 2 and the adjacent surface 23 of the block in the region between the roller 5 and the take-off point of the fibres, which constitutes a fibre-passage 25 first decreasing and then increasing. Fixed to the top of the block is a cover 10 in which a spinning-chamber 11 is mounted for rotation. This has ventilating- apertures 12, a collecting surface 13 and a sliding surface 14, a shank 16 with a driving pulley 17 and a withdrawing tube 18 for the yarn. The open end of the chamber rotates in a groove in the block formed by a projecting part 27 at the fibre take-off point, the groove merges with the fibre-passage 25 and the edge 15 of the spinning chamber lies close to the surface of the combing-roller and acts to doff the fibres with the assistance of the reduced pressure existing inside the chamber. The radial distance of the edge 24 of the projection 27 from the rotational axis of the chamber is only slightly smaller from that of the edge 15. The air drawn out of the chamber centrifugally escapes from the cover 10 through a channel 21 in Fig. 2 not shown the cover is so constructed that the air is conducted to a point behind the edge 15 at the doffing point to assist the doffing action.

The spacing between adjacent ribs is greater than the length of the ledges 19, so that the connector assembly can be inserted, and withdrawn from, between the rails when it is positioned between adjacent ribs. Individual connector assemblies are clamped in position by means of a plate 76, slidable in grooves 80 in the rails 10, 12. Complementary longitudinal projections 86 and grooves 84 in the rails allow two or more mounting channels to be joined. In a modification (Fig. 17, not shown) pairs of connector assemblies may be mounted back to back between rails having upper and lower sets of ribs for abutting upper and lower ledges on the combined connector housings. In each individual connector assembly 2, Figs. 2 and 11, sockets contacts 52 are positioned in a plurality of passageways 30 in an insulating housing 14, so forming a module. A resilient sealing block 18 is bonded to its upper side and has aligned passageways 24 covered by a puncturable membrane 25, through which the plug part (Fig. 3, not shown) is inserted. A compressible barrier insert 38 fits into a recess 34 in the housing 14 and has a plurality of openings separated by walls 40, through which the sockets are inserted into the housing. They are held in position by a closure plate 16, bonded to the housing, which also compresses the insert 38, so forming a peripheral seal. The housing may be of diallyl phthalate, and the sealing members 18, 38 of silicone rubber. Constrictions in the block 18 facilitate gripping of the plug lead. The sockets themselves are made by stamping and bending operations on a laminated sheet metal strip which comprises a base portion of a springy metal such as beryllium copper and a contact portion of a highly conductive metal, for example pure copper which extends over only part of the springy layer. The sockets include both blanked out contact springs and blanked out retaining springs which abut a shoulder on the plug. The plug may be removed by the insertion of a retraction tool which forces the springs outwards off the shoulder. The sockets are moved closer by folding the carrier strip to form bridging portions 70, Fig. 11. By suitable severing of these portions, selected combinations of-sockets only may be commoned. Sockets may be connected by parallel strips 248, 249, Fig. 8, which are themselves joined by rings 253. A socket 252 is located at each end of each ring. (For Figure see next page)

Patent ES-398554-A1 (ES)
Title: Pcm telecommunication system with tdma voice transmission
IPC: H04J3/17
Filed: 1971-12-15
Abstract: A terminal of a pulse-code-modulation (PCM) time-division multiple-access (TDMA) telecommunication system, serving for the exchange of digitized message samples in the form of interleaved multibit pulse codes between a multiplicity of local channels and a like number of remote channels accessible through another terminal, has K associated processing stations each serving n 30-channel groups whose incoming lines are sampled by respective group coders. Each station includes a multiplexer for the outputs of respective group coders whose access to the multiplexer is controlled by a gate in response to a binary activity pattern read out from an associated buffer register, this activity pattern being stored in a memory and periodically updated under the control of respective monitoring units which test the instantaneous condition of the several incoming lines feeding each group coder. The gate blocks the inscription of blank codes from inactive lines in a shift register individually assigned to each group, the shift register thus containing only significant pulse codes from active lines which are read out at high speed to the multiplexer together with allocation bits derived from the activity pattern to inform the remote terminal of the origins of the individual pulse codes in a composite word transmitted during a frame of 125 mu sec, the frame being divided into a number of subframes each assigned to a respective station and consisting of a predetermined number of time slots established by a programmer extra bits may be included in each composite word to make up the allotted number of time slots. At the receiving end, the reverse procedure is followed with restoration of the individual pulse codes to their original relative time position, in respective scanning intervals of a frame, prior to their distribution to the outgoing lines for which they are intended.
