Title: Universal, environmentally secure, wave defense systems using modular caissons
Inventor: CHATTEY NIGEL
IPC: E02B3/06
Filed: 1994-05-20
Abstract: A system of standardized, ballastable, trimmable modular caissons (30) is provided for constructing universal, environmentally secure, wave defense systems for use over a wide range of site conditions in bodies of water of various types and depths and subjected to any kind of storm or tsunami. The modular system comprises one or more different types of primary modular caissons of five standardized shapes and proportions, wherein each different type of caisson module has bulk storage capability and is designed to perform one or more specific functions in the overall wave defense system. The caisson modules (30) can be suitably scaled to size and assembled in different combinations to construct a multitude of differently configured wave defense systems. The individual caisson modules can be manufactured in shipyards or shipyard-type facilities on shore and then towed to, and assembled at, the site where the wave defense system is required. Due to the modular nature of the wave defense system, it can be demounted and the caisson modules readily removed at the end of the useful life of the wave defense system, thereby returning the site as closely as possible to its preconstruction state.

Filed: 1995-11-21
Abstract: A system and method for machining muntin sections and seating bars for assembly into muntin lattices using machines that notch and crimp the muntin sections and a device that pierces the seating bars.  The notching machine has a notching device that forms notches in the muntin section.  The crimping machine has a crimping device that forms dimples in a portion of the notched muntin sections.  The piercing machine has a piercing device which forms apertures in the seating bar to receive muntin section keepers.  The crimped muntin sections are assembled to the non-crimped muntin sections to create the pattern for the lattice with the dimples locking the muntin sections together.  The assembled muntin sections are assembled to the seating bars using the keepers to produce an assembled lattice which is inserted between or upon glass panes of a door or window.
Patent CA-2163630-A1 (CA)
Inventor: PATEL JAYANTILAL SHAMJIBHAI
IPC: H04B10/2513
Filed: 1994-05-26
Abstract: A frequency-selective optical switch capable of switching separate optical signals in a physical input channel to a selected output channel. A diffraction grating (12) spatially divides the input channel (10) into its frequency components, which pass through different segments of a liquid-crystal modulator (24). The liquid-crystal modulator segments (20, 22) are separately controlled to rotate the polarization of the frequency channel passing therethrough or to leave it intact. The channels then pass through a polarization-dispersive element (28) which spatially separates the beams (14, 16) in the transverse direction according to their polarization. A second diffraction grating (40) recombines the frequency components of the same polarization into multiple output beams (42, 44).
Patent CA-2163689-A1 (CA)
Inventor: CHAINER TIMOTHY JOSEPH
IPC: G11B5/596
Filed: 1995-11-24
Abstract: A mechanism for servowriting on a storage medium of a storage device. The storage device has a transducer and a servo loop for positioning the transducer with respect to the storage medium. At least one transition is written on a track of the storage medium, while servoing on other transitions previously recorded on the storage medium. A reference waveform is derived as a function of a closed loop response of the servo loop and a position error waveform. The position error waveform corresponds to one or more position errors of the transducer relative to the previously recorded transitions. The reference waveform is usable in writing subsequent tracks on the storage medium. Using the reference waveform for writing subsequent tracks provides a substantial rejection of mechanical disturbances by the servo loop.

Title: Equipment for recognising when synthetic fibre cables are ripe for being discarded
Inventor: DE ANGELIS CLAUDIO
IPC: G01N3/56
Filed: 1996-02-13
Abstract: With this equipment, the ripeness for the discarding with synthetic fibre cables (5) for lifts can be ascertained. The principle of the recognition of ripeness for the discarding is based on the combination of two fibre types with different properties into one strand (18). The one fibre, the carrying aramide, has a high bending fatigue strength and a high specific elongation. The other fibre, a conductive carbon fibre (19) has a more brittle behaviour.      Both fibre types are twisted into one strand (18). In running operation, a carbon indicator fibre (19) will in every case tear or break, by reason of too great elongations or too great a number of bending cycles, earlier than the carrying aramide fibres of a strand (18). The number of the torn carbon indicator fibres (19) can be ascertained with the aid of a voltage source. In order that a remaining carrying capacity of the cable (5) can be assured, only a certain percentage of the carbon indicator fibres (19) may fail.      Then, the lift is automatically moved into a predetermined stopping place and switched off.

Filed: 1994-12-22
Abstract: A cross-linkable acrylic copolymer having reduced amounts of silane functionalized monomeric units has been found to achieve unexpectedly superior adhesive, cohesive and flexural properties when used in a sealant formulation as compared with known silane functionalized acrylic copolymers. More particularly, it has been found that by reducing the amount of silane functionalized vinyl addition type monomer to less than 1 molar part per 100 molar parts of (meth)acrylate monomer, and reducing the amount of mercaptosilane chain transfer agent to less than 1 molar part per 100 molar parts of (meth)acrylate monomer, it is possible to obtain a copolymer which is capable of being used in a sealant formulation which exhibits vastly improved elastic properties, which are important for high movement sealant formulations, and improved adhesion to metal and glass substrates, while retaining other important sealant properties.

Abstract: An optical projection reduction system used in photolithography for the manufacture of semiconductor devices having a first mirror pair, a second field mirror pair, and a third mirror pair.  Electromagnetic radiation form a reticle or mask is reflected by a first mirror pair to a second field mirror pair forming an intermediate image.  A third mirror pair re-images the intermediate image to an image plane at a wafer.  All six mirrors are spherical or aspheric and rotationally symmetrical about an optical axis.  An annular ring field is obtained, a portion of which may be used in a step and scan photolithography system.  In another embodiment, weak refracting elements are introduced to further reduce residual aberrations allowing a higher numerical aperture.  In the catoptric embodiment of the present invention, a numerical aperture of 0.25 is obtained resulting in a working resolution of 0.03 microns with electromagnetic radiation having a wavelength of 13 nanometers.  The optical projection reduction systems are intended for use at extreme ultraviolet to the soft X-ray wavelength range.  The present invention, provides a relatively high numerical aperture and uses substantially all reflective elements, greatly facilitating the manufacture of semiconductor devices having feature sizes below 0.25 microns.

Title: Leadframe for an encapsulated optocomponent
Inventor: ERIKSEN PAUL
IPC: H01L31/0203
Filed: 1995-10-19
Abstract: In encapsulating an optocomponent a leadframe is used for the electrical connection of the component, the leadframe having a flag, to which the main body of the optocomponent is attached. The flag is located asymmetrically at an outer edge of the leadframe and is, in the encapsulating operation, placed close to a sidewall in a mould cavity in a mould.      Thereby an optical interface of standard type can be obtained in the wall of the capsule. Further, the flag is flexibly attached, by means of zigzag-shaped bridges, to other portions of the leadframe so that the flag and thus the optocomponent will have a possibility to be resiliently and flexibly displaced a little at the positioning thereof the mould cavity in the mould in relation to the other portions of the leadframe, in particular to its outer frame portions and bridge portions. By designing the zigzag-shaped bridges with a suitably adapted width and thickness a controlled elastic restoring force acting on the flag can be obtained and thus on the optocomponent, so that it can be pressed and firmly retained in engagement with positioning means for the optocomponent.
