Title: Methods of producing light effects
IPC: A63J5/02
Filed: 1930-04-26
Abstract: 359,921. Theatrical appliances. WHITING, W. J., Potmae Park Apartments, Washington, U.S.A. April 26, 1930, No, 12937. [Class 132 (i).] Various optical effects are produced by utilizing lights differing partly or wholly as to their spectral compositions but having the same spectral centre of gravity, this centre being defined as the centre of gravity of the area enclosed between the luminosity curve and its wavelength axis. For example, the composition represented by Fig. 8 has a bright band II in the blue-green and a bright band IV in the red, while the wholly differing composition of Fig. 10 has a bright band I in the violet and a bright band III in the yellow. It is stated that these two compositions have the same centre of gravity C.G. and appear alike to the eye, both being substantially white. If a scene is illuminated by these two compositions successively changes will appear therein, depending on the colours of objects in the scene and the colour of the background, although there is no apparent change in the nature of the illumination.

Title: Optical wave guide
IPC: G02F1/095
Filed: 1976-03-31
Abstract: 1529266 Controlling light COMMISSARIAT A L'ENERGIE ATOMIQUE and AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE ANVAR 31 March 1976 [2 April 1975] 12940/76 Heading G2F In an optical waveguide the guiding layer is of magnetizable material and is constituted by at least two stacked layers or layer regions having a different gyrotropy i.e. the non-diagonal part of the permittivity tensor. The layers may be of the same material but with different, e.g. mutually perpendicular, directions of magnetization produced for example by ion implantation, or they may be magnetized in parallel directions but of materials with different magneto-optical characteristics. By controlling the parameters of the layers (thickness, refractive index, gyrotropy) the variation in gyrotropy across the thickness of the guiding layer may be adjusted to optimize the coupling between two propagating modes. Alternatively the phase velocity of a propagated wave may be so controlled as to provide a much shorter optical isolator than those of the prior art. As particularly described, non-reciprocity is obtained by providing layers magnetized in antiparallel directions across the thickness of the guiding layer.

Title: Improvements in Recoil Brakes for Guns.
IPC: F41A25/02
Filed: 1919-05-27
Abstract: 134,192. Schneider et Cie. Oct. 25, 1918, [Convention date]. Recoil apparatus.-Relates to hydraulic brakes of the kind in which the recoil stroke is variable, and in which the brake cylinder A and run-out control ram B recoil together the brake piston-rod D being connected to a non-recoiling part F of the mounting. The invention consists in combining with the normal brake passages additional passages for the braking-fluid, which passages are controlled by a spring-loaded valve. A number of constructions are described, one of which is shown in Fig. 1, and another in Fig. 34. As shown in Fig. 1, the normal braking-orifices are formed by ports c in the piston-head E co-operating with ports d<1> in the rotatable liner D<1> of the piston-rod D. The additional passages consist of wide ports e<1> in the piston E coacting with a similar number of narrow ports i in a collar I formed on the rotary liner D<1>. The spring- pressed valve is a flanged ring H slidable on the liner D<1>. The ring I has also a port i<2> coacting with a run-out relief valve K in the valve-plate H. For normal recoils, the ports c, d<1>, and also the ports e<1>, i, are in register; but, with increased elevation, the liner D<1> is automatically rotated, and, while the ports c, d<1> still register, the collar I throttles or wholly closes the ports e<1>, and a shorter recoil results. In the construction shown in Fig. 34, the throttling is effected between the ports c, d<1> by rotating the liner D<1>, and the collar I between the valve H and the piston E is omitted. Instead of the run-out relief valve K, Fig. 1, the ports e are uncovered during the run-out by a forward sliding of the liner D', for which purpose the front end of the liner engages with play in a socket J on which is mounted the toothed sector j of the automatic regulating-mechanism. The run-out control valve C, instead of being formed on the control-rod B, as shown in Fig. 1, is carried in the end of the liner D' ; during recoil, liquid passes into the front end of the liner through the port 2 in the piston-rod D, and through the ports q, c in the front end of the liner and in the valve C. In other constructions, the spring-loaded valve may be held more or less off its seat in the adjustment for long recoils, and is fully operative only in the adjustment for short recoils.
