Title: An optical detector
IPC: G02B6/00
Filed: 1990-09-13
Granted: 1993-05-13
Abstract: PCT No. PCT/GB90/01416 Sec. 371 Date Apr. 20, 1992 Sec. 102(e) Date Apr. 20, 1992 PCT Filed Sep. 13, 1990 PCT Pub. No. WO91/04617 PCT Pub. Date Apr. 4, 1991.An optical detector for use in detecting digital optical signals has an optical fiber coupler which splits a received optical signal into two signal portions. The coupler has unequal length output fibers so that one signal portion impinges upon an associated photodetector delayed relative to the other. The photodetectors are connected in series nonopposed when the delay is equal to the bit period of the optical signal the output of the detector is the differential code (dicode) of the received signal which can be recovered by a high input impedance, i.e. integrating, amplifier. By forming the dicode in the optical domain in this manner large DC and AC dynamic ranges are obtained without linearity constraints on the optical transmission source that apply when the optical signal is transmitted as a dicode.

Title: Process for the production of ultrafine particles
Inventor: MCCORMICK PAUL GERARD
IPC: C01F17/224
Filed: 1996-08-28
Granted: 1999-09-30
Abstract: A new, cost effective process for the production of ultrafine particles which is based on mechanically activated chemical reaction of a metal compound with a suitable reagent. The process involves subjecting a mixture of a metal compound and a suitable reagent to mechanical activation to increase the chemical reactivity of the reactants and/or reaction kinetics such that a chemical reaction can occur which produces a solid nano-phase substance. Concomitantly, a by-product phase is also formed. This by-product phase is removed so that the solid nano-phase substance is left behind in the form of ultrafine particles. During mechanical activation a composite structure is formed which consists of an intimate mixture of nano-sized grains of the nano-phase substance and the reaction by-product phase. The step of removing the by-product phase, following mechanical activation, may involve subjecting the composite structure to a suitable solvent which dissolves the by-product phase, while not reacting with the solid nano-phase substance. The process according to the invention may be used to form ultrafine metal powders as well as ultrafine ceramic powders. Advantages of the process include a significant degree of control over the size and size distribution of the ultrafine particles, and over the nature of interfaces created between the solid nano-phase substance and the reaction by-product phase.

Title: Method and device for recycling pet materials
Inventor: BACHER HELMUT
IPC: B29B13/06
Filed: 2000-09-22
Granted: 2003-12-04
Abstract: Within a process for recycling of PET-material and/or objects of PET, the PET-material to be processed is heated and dried in the course of a pre-treatment step and simultaneously is crystallized at elevated temperature. This pre-treatment step is followed by a main-treatment step under vacuum. In this main-treatment step, the processed material is again dried and crystallized at a temperature that is higher than the temperature of the pre-treatment step. Preferably, also in the main-treatment step no plasticizing of the material takes place; the plasticizing or, respectively, melting of the material takes place only after the main-processing step. An apparatus for performing this process comprises a pre-processing device ( 3 ) in which the processed material is dried and simultaneously crystallized at elevated temperature, and, if desired, is also comminuted. A main-processing device ( 4 ) is connected to this pre-processing device ( 3 ), in which main-processing device the supplied PET-material is dried, crystallized and heated to a temperature that is higher than the temperature within the pre-treatment device.

Filed: 1991-12-03
Granted: 1994-04-28
Abstract: Bromonitroethenylfuran (BNEF) is prepared from furfural in a two-step process. A primary amine is reacted with furfural in an organic solvent at the reflux temperature of the solvent to form the Schiff base. The organic solvent and the water formed in the foregoing reaction are removed from the Schiff base, which is then dissolved in a polar, water-miscible solvent. Bromonitromethane is added to the Schiff base solution and reacts with the Schiff base to form BNEF, which can be readily isolated by precipitation.

Title: Laser energy absorption determination - by comparison with temperature rise by black body absorption
IPC: B23K26/03
Filed: 1968-11-07
Abstract: The efficiency of laser pulses used for welding is measured by measuring the temp. rise in the workpiece when the latter is arranged as a black body, i.e. when all the laser energy impinging on it is absorbed and converted to heat. The energy is determined by the energy stored in a capacitor which brings about the same temp. rise. The ratio between the temp. rise produced by a laser beam in a prodn. arrangement to that of a black body indicates the proportion of laser energy absorbed. If the amount of energy absorbed by the workpiece is known, optimum treatment conditions can be specified. The result is a better quality of weld.

Abstract: A driving and positioning system consisting of a rotor equipped with permanent magnets and of a stator with at least two windings. The windings are connected to an electronic voltage-supply circuit controlled by rotor-position sensors for commutating the current.

A practical electronic voltage-supply circuit for controlling the system is also described. It has two sets of multiplication stages and a set of addition stages in a prescribed layout.

Abstract: Encapsulated liquid crystal material in a support medium illuminated from the viewing side or direction or though a louvred light guide from the back side will appear bright or white relative to background when in distorted alignment, e.g. in the absence of an electric field. Incident light impinging on the liquid crystal material is isotropically scattered into the support medium, and using the principle of total internal reflection and possibly also optical interference a relatively large part of the isotropically scattered light is directed back to illuminate the distorted liquid crystal material tending to brighten the same so that light it scatters back to the viewing direction out of the support medium causes the liquid crystal material to appear relatively light or bright as compared to the background where there is no liquid crystal material or where the liquid crystal material is in parallel alignment in field-on condition, i.e aligned with respect to an electric field, and, thus, substantially transmissive. Original incident light where there is no liquid crystal material, that light which is isotropically scattered toward the back or non-viewing side of the display and within a certain cone or solid angle, and that light passing through aligned (field-on) liquid crystal material will tend not to be totally internally reflected; such light will pass through the support medium and may be absorbed by a remote black or colored material.
