Title: Intraocular lens with a non-uniform Fresnel prism array
Inventor: TOOP PETER
IPC: A61F2/16
Filed: 2009-11-23
Abstract: An intraocular lens 10 is described, one face of which comprises a linear Fresnel prism 12 array having several prism elements. The prism elements 12 are non-uniform in size and/or pitch and each have an angled facet. The light is deviated from the optical axis via the prism elements 12 to an off axis position. The off-axis position lies in between the optical axis and a line perpendicular to the angled facets. The facets are modified so as to reduce diffraction effects and astigmatism associated with the Fresnel prism. By varying the pitch of the prism elements 12 across the array, which may comprise varying their size, a diffraction grating effect can be reduced or negated. The light incident on the lens is preferentially directed into the zero order diffraction direction and chromatic angular dispersion is reduced. The lens 10 may also be used to treat macular conditions.

Title: Improvements in or relating to pressure medium braking and steering gear for aircraft
IPC: B64C25/48
Filed: 1931-04-02
Abstract: 366,344. Fluid-pressure brakes. KNORR-BREMSE AKT.-GES., 9, Neue Bahnhofstrasse, and GRUNO, B., 2, Dirschauerstrasse, both in Lichtenberg, Berlin. April 2, 1931, No. 10114. [Class 103 (i).] In fluid-pressure braking and steering gear for aircraft having a brake valve controlling the brake cylinders on each side of the aircraft, movement of the brake-controlling lever in the vertical central plane between the valves causing uniform operation of the valves and rotation of the lever opening one valve and closing the other, the passage connecting the brake cylinders for equalizing the braking effect on equal operation of both valves, is controlled by one rotary valve which is not rotated when the brake lever is moved for equal braking on both sides of the aircraft. Movement of the lever c in the direction of the arrow indicated in Fig. 2 operates both valves a, b to supply pressure fluid to the brake cylinders on both sides of the machine through passages r, s, by means of bell cranks f and rods e connected to transverse arms d on the lever. Rotation of the lever about a vertical axis depresses one bell crank f and raises the other so that only one valve is opened. The passages to the brake cylinders on each side are connected and the pressures equalized through a passage t in a rotary valve q. A forked member m embraces a plate o connected to the valve q and is hinged to the lever c by a pin u. The lever c is rotatably guided in a s leeve h mounted in journals i moving in bearings k. The centre lines of the journals i and the pin u coincide, so that no movement of the rotary valve q takes place when the lever c is depressed for uniform braking. When however the lever is rotated to operate one brake valve only the rotary valve is turned to disconnect the brake ducts on each side from one another. Each of the valves a, b comprises a piston 9, which on operation of the valve is depressed by the bell crank f, a spindle g and a spring 11 to close an atmospheric outlet 10 against a valve v which is also depressed to remove a packing y from a seating z and thus connect the fluid supply pipe to the chamber 17 connected to the brake cylinder ducts. A duct 6 in the valve v allows fluid to flow beneath the valve and allows the spring x to return it against the seating z to maintain a desired pressure. Corrugated resilient bodies 8, 15 prevent escape of fluid past the guiding piston w of the valve v and past the piston 9.

Title: Improvements in or relating to lens mountings
IPC: G02B7/02
Filed: 1944-05-31
Abstract: 603,569. Lens mounts. INTERNATIONAL POLAROID CORPORATION. May 31, 1944, No. 10492. Convention date, July 14, 1943. [Class 97 (i)] To minimise thermal effects a lens is mounted in a sleeve secured in a housing which engages the opposite end portions of the sleeve, the housing having a coefficient of thermal expansion less than that of the lens. As shown in Fig. 7, the sleeve 44, of synthetic resin, supports lenses 10, 12, also of resin by pins 46 engaging slots in the lens, and is supported in a housing 50 of metal or phenolic resin, which carries a fixed bevel flange 52 engaging a correspondingly bevelled end of the sleeve. The sleeve is pressed against flange 52 by a bevelled ring 54, held by a locking ring 56. The sleeve is so supported as to have a clearance between it and the housing and the bevelled ends of the sleeve are slotted to prevent breakage when expansion takes place. The pin mounting of the lenses permits their expansion relative to the sleeve and the bevels ensure that the lenses remain centred as temperature changes. In a modification the bevels are omitted. The lenses are preferably of the same material as the sleeve and may comprise polycyclohexyl methacrylate, polystyrene or the polymerizable transparent acrylic and methacrylic esters, cyclohexyl methacrylate, methyl methacrylate, alpha phenyl ethyl methacrylate, phenyl methacrylate, benzyl methacrylate, orthomethyl styrene, ortho-chloro styrene, tetrahydro-furfuryl methacrylate and menthyl methacrylate. Lenses of glass may also be used. The lenses may be bonded directly to the sleeve as shown, for example, in Fig. 3, where a bond 28 is formed by pouring synthetic resin through apertures 30 in the sleeve 18a. Alternatively, internal ridges may be formed as the sleeve to which the lens is formed by suitable solvent or the edge of the lens may be cemented directly to the inside of the tube. Example of suitable cements are given. In the modification shown in Fig. 9, a rim 70 of synthetic resin is provided to mount the smaller lens 66 within the resin sleeve 68 which is supported within a housing 80, of a material having a coefficient of expansion differing from that of the sleeve, by fingers 68c carried by reduced ends 68b of the sleeve, the latter being held against a flange 82 by a resilient ring 86 of cork or rubber fixed by a ring 84. These mountings prevent distortion of the lenses with changes of temperature and the sleeve also provides thermal insulation.
