In another embodiment, the ends may be joggled between dies H, H 1 , Fig. 6, before bending over. In a further embodiment a component with radially extending wires has the ends flattened by oppositely acting dies, Fig. 5 (nto shown); the ends may then be joggled, Fig. 8 (not shown). The flattened ends may also be twisted to bring the flat surfaces parallel with the component axis, Fig. 9 (not shown).

Title: Improvements in or relating to telecommunications exchange systems
IPC: H04L12/52
Filed: 1970-09-11
Abstract: 1286800 Telegraphic exchanges SIEMENS AG 11 Sept 1970 [12 Sept 1969] 43465/70 Heading H4P In a programme-controlled digital data exchange where incoming lines call-up a central store, address signals selecting a particular incoming or outgoing line also perform a command function to initiate such operations as sampling or changing the polarity of lines. In the arrangement of Fig. 2 incoming lines ZL and outgoing lines AL are connected to line circuits, so called system connections SA, which are grouped in groups of eight consecutive lines, corresponding to the 0-7 units placings of their octal-coded addresses. A change in polarity of an incoming line causes its thousands, hundreds, tens and units leads to be marked and a mixing circuit M provides an address signal of the line comprising a unique combination of four marks on parallel leads. A four-stage hunting cascade SK provides a coded output at its four outputs (T), Ha, Za, Ea which is converted into a binary signal by coder Cod for supply to a control UEAS and a store (not shown). To sample the polarity of the so identified line, the binary coded address is supplied to a decoder Dec and a polarity command signal to an operations control OP by the control UEAS. By means of the various mixing circuits ladelled CW in Fig. 2, the thousands, hundreds and units digits of the address of the calling line are supplied via channel HEE to ready all the system connections having that part of their addresses in common, whereas the tens digit of the address is supplied to the operations circuit OP where a sampling command signal PE is sent only to that systems connection group SAG corresponding to the tens digit. Only the line circuit of the calling line is thereby activated to transmit the polarity of the line via lead PA back to control UEAS. Particular line circuits can therefore be made to perform different operations by appropriate choice of address to the decoder Dec and command signal OP, for instance the relaying of the change of polarity to an outgoing line is signalled via leads S0, S1 or if reversal of polarity by U0, U1. A polarity comparison circuit is reset via a signal on lead R0 or R1. Monitoring or fault-finding circuitry (not shown) is provided to simulate a change in polarity on each line in turn to check the identification and hunting operations. To expand the system, several system con nection devices SAE may be provided, each with its own input and output code converters ECW, ACW, and having different orders of priority (Figs. 4, 4a, 4b, not shown).

Abstract: 924,508. Velocity-modulated tubes. MULLARD Ltd. Dec. 23, 1959, No. 43706/59. Class 39 (1). The magnetic focusing assembly of a velocitymodulated tube, preferably a backward wave tube, comprises inner and outer tubular walls 10, 12 closed by end plates 11 accommodating three magnetic coils 22 or permanent magnets and surrounding the discharge tube, cooling fluid, e.g. air, flowing in through an aperture 28 in one end plate and out through apertures in the inner wall 10. The coils are mounted on a cylinder 23 and the outer surface of cylinder 10 and the inner surface of 23 are covered with insulation, e.g. by anodising, if of Al, so that a current lead to the coils can be connected to tube 23. There are three sets of four circumferentially disposed aligned apertures 21, 20, 27, so that cooling air after flowing around the annular space 13 passes through these apertures and then upwards. The cooling air may flow in the opposite direction. A conical rubber member 5 prevents escape of air downwards. Bearing members 14 locate cylinder 6 within cylinder 10, and cap 2 is held in position by radial screws threaded through the shell 6, as described in Specification 924,507.

Filed: 1972-09-21
Abstract: 1385737 Aerials THOMSON-CSF 21 Sept 1972 [22 Sept 1971] 43847/72 Heading H4A A multi-beam aerial system comprises a polarization-changing main reflector, a polarization changing sub reflector and a plurality of off-set feed sources. Each reflector has an axis of symmetry, the two axes being concurrent, and a reflecting surface symmetrically disposed thereabout, the two surfaces being shaped to provide aplanatism. The system further comprises a member which is transparent to waves having one kind of polarization and which is reflective of waves having another kind of polarization, said member being interposed between the feed sources and the two reflectors. As described, a feed system 3, Fig. 3, consists of independent sources 30, 31, 32, and respective differently-directed beams are produced therefrom by a reflecting system which comprises a sub-reflector 2 and a main reflector 1. Said reflectors have shapes which are related to the Schwarzchild surfaces, so that the system is aplanatic. The feed system 3 and the subreflector 2 have the same axis, which intersects the axis of the main reflector 1 at right angles at a point A. A plane member 4, which is made up of parallel wires 41, perpendicular to the plane of the figure, is disposed through the point A. Waves from the feed sources are polarized parallel to the plane of the figure, as is shown by P for the source 30, and pass freely through the member 4 to the sub-reflector 2. Here the plane of polarization is rotated by 90 degrees by a twist reflector 21, as is shown by P1, and the waves from the sub-reflector are now reflected by the member 4, to the main reflector 1. Here the plane of polarization is rotated a further 90 degrees by a twist reflector 11, as is shown by P2, and the waves now pass through the member 4, to emerge as a beam in a direction FG. Beams in other directions are similarly derived from the remaining sources, e.g. in a direction KL from the source 32. The sources are sufficiently offset from the axis of the main reflector to prevent aperture blocking. The twist reflectors 11, 21 comprise networks of parallel wires disposed at 45 degrees to the direction of polarization and placed a quarter wavelength from the surfaces of the reflectors 1, 2. The aerial system may be installed in a communications satellite which is required to co-operate with a number of spaced-apart earth stations.
