Filed: 1955-11-16
Abstract: 785,773. Automatic adjustment devices for brakes. GOODYEAR TIRE & RUBBER CO. Nov. 16, 1955 [June 17, 1955], No. 32751/55. Class 103 (1). In an automatic adjustment device for a brake, an adjustment pin is secured to and extends from the brake lining positioning member and a sleeve is releasably mounted on the pin wherein friction means engaging the sleeve retards movement of the adjustment pin, and upon release, the pin can be removed from the sleeve without disturbing the engagement of the friction means with the sleeve. In the embodiment illustrated in Fig. 1, the automatic adjustment device is incorporated in a disc brake assembly in which rotatable axially slidable brake discs 5 carried by a suitable wheel (not shown) are braked by means of non-rotatable friction linings 14 and 16 mounted on axially slidable brake lining positioning members and urged by an hydraulically operated annular piston 8 to the right into frictional contact with brake lining 15 carried by end member 3 of fixed brake housing 2. The automatic adjustment apparatus consists of an adjustment pin 17, secured to the annular brake pressure plate 7, and carrying a sleeve 21 abutting at one end against the pressure plate 7 and the other end against a locked nut 19. A friction means 22 tightly engages the periphery of sleeve 21 and a spacer sleeve 23 being a forced fit on sleeve 21 bears against the axial outer end of the friction means 22, the opposite end of the friction means seating against the flange 25 of a locating sleeve 26 which, in turn, bears on member 27 rigid with brake housing 2. In operation, the sleeve and adjustment pin 17 move as a unit with the brake pressure plate 7 and as lining wear occurs, the friction means 22 will be moved against the member 27 to be held in position while the pin 17 and sleeve 21 are moved inwardly of the brake to effect adjustment. To provide clearance in the brake upon release of the braking forces, coil spring 28 carried by locating sleeve 26 abuts the member 27 and flange 24 of spacer sleeve 23 to move pin 17 and brake pressure plate 7 axially outwardly by the distance covered by the axial clearance between the flange 24 of spacer sleeve 23 and the inner surface of cover 29 rigid with brake housing 2. When servicing the brake the nut 19 may be removed from the pin so that it can be removed with the pressure plate 7 from the brake without altering the relationship between the sleeve 21 and friction member 22.

Title: Magneto-optical propagation mode converter

Filed: 1975-08-08
Abstract: 1518119 Controlling light THOMSON-CSF 8 Aug 1975 [9 Aug 1974] 33247/75 Heading G2F An optically uniaxial optical guiding layer of a ferrimagnetic garnet is grown epitaxially on a non- magnetic garnet substrate and is subjected to a magnetic field having at least a component transverse to the optical propagation direction so that it exhibits induced birefringence (Cotton-Mouton effect) such that the propagation velocities of a TE and TM mode therein are rendered equal (for a predetermined wavelength) and one is substantively converted to the other, i.e. without the new mode undergoing destructive self-interference due to phase mismatch between the TE and TM modes Fig. 2 shows a plot of refractive index N against kW, where k is the (predetermined) wave number and W is the waveguide thickness, for such a guide and for the TE and TM modes. The intersection at D determines W for the predetermined value of k. In first and second embodiments, the guiding layer is magnetized at 90 degrees to the optical propagation direction, and in the plane of the layer or at 45 degrees thereto respectively. If the magnetization direction is other than at 90 degrees to the optical direction, both the Faraday and Cotton- Mouton effects are operative. Together with a polarizer (mode selector) such a device acts as an isolator e.g. for the TE mode, since the effects add in one propagation direction and subtract in the other, due to the non-reciprocal nature of the Faraday effect. Alternatively a non-reciprocal device 21 using the Faraday effect may be disposed between a mode selector 20 and a reciprocal device 22 as described above, with magnetization at 90 degrees to the optical direction, to provide optical isolation. The device 21 likewise comprises a ferrimagnetic YIG garnet layer on a non-magnetic garnet substrate, the layer being magnetized with components orthogonal and parallel to the optical direction so that mode conversion by the Faraday effect occurs cumulatively due to TE-TM phase matching. Both the devices 21, 22 convert a single input mode to two modes of like intensity, and effectively add or subtract according to the optical direction so that a TE mode transmitted by the mode selector 20 is transmitted to 26 unchanged, but a TE mode directed from 26 through the two devices is converted to a TM mode and is absorbed at 20.
