Title: Rotation-asymmetrical junction circulator
IPC: H01P1/387
Filed: 1969-08-29
Abstract: 1,235,249. Circulators. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 29 Aug., 1969 [4 Sept., 1968]. No. 43161/69. Heading H1W. A 3-port junction circulator comprises two ports 4, 5 angularly spaced at 120 degrees and a third port 6 spaced at 60 degrees from either of the ports 4, 5. The diagram of Fig. 3 shows the standing electric wave which is distributed around the periphery of the .ferrite elements 7, 8 when a signal is applied to port 4 and coupled to port 5. In the normal (symmetrical) type of circulator, the port 6 is positioned at 6<SP>11</SP> (240 degrees from port 4) where a node in the standing wave pattern occurs. According to the invention, the alternative position 6<SP>1</SP>, also at a node, is chosen for port 6. The standing wave pattern generated when a signal is applied to port 5 consists of a sinusoid with a node at position 4 and an antinode between positions 5 and 6<SP>1</SP>. The patterns indicate that ports 5-#6 and 6-> 4 are coupled in phase and ports 4-> 5 in phase opposition. In a development of the invention (Fig. 5, not shown) a fourth port is added at the (normal) position 6<SP>11</SP> giving a circulator having ports designated -4,5, 6<SP>1</SP>, 6<SP>11</SP>. A signal applied to port 5 is coupled in phase to port 6<SP>1</SP> and in antiphase to port 6<SP>11</SP>. Signals applied to both ports 6<SP>1</SP> and 6<SP>11</SP> are coupled to port 4 only insofar as the two signals are in antiphase, components having the same phase being reflected. The circulator may be used to couple electrically symmetrical with asymmetrical devices or, by suitably arranging the terminal impedances of ports 6<SP>1</SP>, 6<SP>11</SP>, to effect power distribution. In an alternative development of Fig. 1, the additional port, designated 5<SP>1</SP>, is positioned opposite the port 5 (at 300 degrees). The ports 5, 5<SP>1</SP> are the equivalent of the ports 6<SP>1</SP>, 6<SP>11</SP> in the previous modification. These two alternative and equivalent developments of Fig. 1 may be combined in the manner shown in Fig. 8 to form a 5-port circulator. The invention may be applied to the type of 4-port circulator formed by connecting a port of one 3- port circulator to a port of a second 3-port circulator. This is done by arranging two circulators a, b of the Fig. 1 type face to face and interconnecting ports I and 3 as shown in Fig. 9. In a modification of-Fig. 9 (Fig. 11, not shown) one of the circulators is of the normal kind. In the modification shown in Fig. 10, the circulators a, b are of the 4-port type in which one port of a Fig. 1 type circulator is duplicated by an opposite port (e.g. port 51 or port 6<SP>11</SP> of the Fig. 8 circulator). The opposed symmetrical ports are designated III<SP>1</SP>, III<SP>11</SP> and 3<SP>1</SP>, 3<SP>11</SP>, and are connected together. In the circulators of Figs. 9-11, a common magnetic field is used for both components.

Abstract: 1,029,307. Tunnels; tunnelling-shields. M. F. KEMPER. Nov. 19, 1962, No. 43691/62. Heading E1F. In a method of forming a tunnel, a shield is driven into the earth, earth is removed from the interior of the shield, a structure is built up within the shield, and the shield is again driven into the earth to leave the structure supporting the overlying earth. The shield 5 has a beam N adapted run over the top of a support A, and an auxiliary support B pivoted to the beam at 8. The shield resting on the support A is advanced from the position shown in Fig. 1 to that shown in Fig. 2 by hydraulic rams 38-43 carried by the shield and bearing against the tunnel lining already erected, the earth face being supported by boards 49, 50, 51 pressed by pneumatic rams 44-47 during the advance. The rams 38-43 are normally each supplied with an equal volume of liquid, but if it is required to check deviation of the tunnel additional volumes of liquid are supplied to selected rams. After the earth has been dug from the shield and the rams 38-43 have been collapsed an arch C is erected in two parts 50, 51 within the shield, and the arch is connected to the existing lining by tie bolts 62, spacers 63 and lagging 57. The arch is then jacked-up by jacks 53, 54 and supported on chocks 60, 60a. The support B is lowered to the position shown in Fig. 2 and is jacked-up to relieve the load on the support A which is then moved by rams 23 to a position similar to that shown in Fig. 1. The support A is jacked up and the support B is pulled up by an air motor 37 so that another cycle of digging and erection may commence.

At least one of the sealing members L, N, Fig. 5, of a rubbing-collar type seal, e.g. the rotary member N, is sealed to the structure with which it is non-rotatably associated by a seal, such as an 0-ring Z, supported by a rigid backing member P and engaging a radial face of the sealing member, the latter being free of radial constraint throughout its axial length and being deformable radially without distortion by the pressure of the fluid to be sealed. The member N, which may be of carbon or steel, is drivingly connected by pins Y to the member P which is in the form of a carrier ring driven through pins X by a retainer ring W secured to a shaft. The member P is axially movable on a sleeve Q and is sealed thereto by a wedge ring R compressed through a thrust ring U by springs V mounted in the retainer W. Fluid pressure acts on the whole outer periphery of the member N, which alternatively may have a symmetrical cross-section, Fig. 6. The member L is stationary and is sealed into a housing by an 0-ring M either on its outer periphery, as shown, or bearing against its inactive radial face. In Fig. 2, the rotary member C<SP>1</SP> is sealed through an 0-ring J to a spring-pressed member C<SP>11</SP> sealingly mounted on a shaft. In Fig. 4, the rotary member C<SP>3</SP> bears against a wedge-shaped semi-rigid member K which is engaged by a thrust ring T which transmts the force from a spring S to the member C<SP>3</SP>.

A base with a hydrophilic surface having a colour-forming component therein is provided thereover with a coating comprising a lightsensitive water insoluble diazo oxide. Exposure and treatment with an alkaline solution containing a further colour component causes solution of the diazo oxide in exposed areas only, permitting reaction of the two components to form a coloured image, after which the sheet may be rinsed and if desired, treated with a solvent to remove residual diazo oxide. The image produced may be used as such or as an intermediate to make further copies. In Example I, a cellulose acetate film is coated with a vinyl methyl ether/maleic anhydride copolymer which is surface-hydrolysed by ammonia, overcoated with a silver nitrate solution and then with one containing N-dehydroabietyl-6- diazo - 5(6) - oxo - 1 - naphthalenesulphonamide, and this material is reflex exposed and processed with a solution including alkylolamines and hydroquinone to give a black image.
