Title: Improvements in or relating to navigation aiding radio systems
IPC: G01S1/02
Filed: 1946-12-20
Abstract: 629,304. Radio navigation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and CLOUGH, N. H. Dec. 20, 1946, No. 37585. Drawings to Specification. [Class 40 (vii)] A navigation-aiding radio station of the overlapping beam type provides an equi-signal line swinging through 180 degrees. Three aerials disposed in a straight line are spaced apart equally a distance of not more than a quarterwavelength, and the centre aerial is energized continuously whilst the outers are energized in oppositely varying phase relationship such that their phases with respect to the centre aerial are (-#+#) and (+#-#) respectively, where # is varied smoothly from 0 to #. Additional changes of # are made to the phases of the outer aerials at predetermined intervals throughout the variation of #. In order to characterize these differently-phased signals the changes are made in the keying rhythm of interlocked signals, such as morse letters E and T. The bearing to the station may be found within the 180 degrees arc on each side of the station by the normal method of counting signals. Where more accurate bearings are required the singleline system may be operated in conjunction with a known multi-line system, Fig. 2, not shown, of the type which provides a plurality of equi-signal lines swinging simultaneously through narrow sections. The two systems are operated alternately; the single-line system resolves the sector ambiguities. A combined station, Fig. 3, (not shown), accordingly comprises five aerials disposed in a straight line with the outer pair spaced symmetrically with respect to the centre aerial several wavelengths apart, and the inner pair spaced <1>/10th of this distance but not more than one half-wavelength. In the sequence of operations the outer pair and central aerial first operate to provide a multiline system for 30 seconds. For this purpose the outers are fed with currents of phases # 7T (+-- #) and (- - - +#), where # is varied 2 2 smoothly from 0 to # in 30 seconds. Additional changes of # are made in the keying rhythm. The inner pair and centre aerial then operate as described above to provide a single-line swinging through 180 degrees in 30 seconds. Between the two operations the station may radiate a call sign. To avoid confusion the multi-line system is keyed at half-second intervals and the single-line system at one-second intervals. The rates of keying and equi-signal line swing are so chosen that a common chart may be prepared for use with both systems, and one single-line signal represents the same angular divergence from an equi-signal line as twenty multi-line signals. The two systems may operate on separate wavelengths, and if these are chosen to provide the correct aerial spacing only three aerials are necessary.

Abstract: 1402451 Positive clutches SOC ANON DE VEHICULES INDUSTRIELS ET D'EQUIPEMENTS MECANIQUES 11 Aug 1972 [13 Aug 1971] 37659/72 Heading F2C The teeth of the axially slidable member 5 of a synchronized dog clutch are formed as spokes 8 adapted to engage in recesses 11 formed in friction cone members 9 secured to the adjacent pinions. The member 5 is formed with teeth 6 meshing with notches 4 in a hub member 3 keyed to the shaft on which the pinions are rotatable. A friction synchronizing ring 12, formed with friction surfaces adapted to be engaged with the corresponding surfaces of the members 9, is formed with apertures 16 which engage the spokes 8 and which have bevellededged recesses 20. Initial movement of the member 5 from its neutral position displaces a spring 18 out of engagement with an abutment 24 on the ring 12 and the relative movement between the ring 12 and the selected pinion causes the spokes 8 to move into the recesses 20 in the ring 12, Fig. 4 (not shown). On synchronization, produced by engagement of the friction surfaces of the cone members 9 and of the ring 12, the spokes 8 move out of the recesses 20 to allow movement of the ring until the spokes 8 engage in the recesses 11 in the members 9. On declutching, the spring 18 will return to the shoulder 24 to locate the member 5 in its neutral position.

In one embodiment two bending heads 4, 5 are provided each having a central abutment bolt 14 and a bending tool 13 mounted for movement around the bolt. The bolt and the tool extend between adjustably positioned discs (15), (16), Fig. 3 (not shown), one of which is removable to permit removal of the bent rod. The head 5 has an adjustable position rod cutter 7. The heads are movable on rails 3 provided with adjustable stops 6 which may have switches to actuate the machine. In operation one or more rods 10 are fed from a bed 1 through the heads which are close together. The head 4 effects a bend in the leading end of the or each rod b, Fig. 5, and then moves away from the head 5. The head 4 serves to hold the rod or rods while the head 5 effects a bend at the other end c. The head 5 is moved towards the head 4 by the distance between the end bend and the bend to be made and effects a further bend d. The movement is repeated for a further bend e. Thereafter the head 5 holds the rod or rods and the head 4 is moved and effects bends f, g. The drive for the heads is provided with a switching off device controlled by the movement of the heads, the drive being automatically switched on after each bending operation. In an alternative embodiment there is only one bending head (101), Fig. 6 (not shown), and a clamping carriage (103) which can be sequentially driven by a piston-cylinder unit (107), (108) or an impulse generator (119). In each case a sequence programme control (117) is used to actuate a valve (111) or a switch (120) to stop the carriage drive. In the first case a timer (115) is used whereas in the latter case the generator is connected to the bending head (101). In a final embodiment, Fig. 7 (not shown), the clamping carriage (103) forms part of a linear motor whose field (121), (122) is set up selectively by a set of energizable segments (123).
