Patent EP-0576115-A1 (EP)
Inventor: EKLUND NILS OLA
IPC: D21F3/00
Filed: 1993-02-22
Abstract: A transfer belt (60) for carrying a paper sheet (40) in a papermachine from a press nip in a closed draw to a transfer point, where it is readily released. The belt comprises a supporting base (62) with a particle-filled polymer coating (80) on its paper-facing surface (66), which surface has a pressure-responsive recoverable degree of roughness. During compression in the nip, the surface (66) becomes relatively smooth to allow a thin, almost continuous water film (100) to form between the belt (60) and the sheet (40), which film holds the sheet to the transfer belt as it leaves the nip. Shortly after leaving the nip, the belt surface recovers its uncompressed roughness, breaking up the water film so as to facilitate the release of the sheet from the belt as it reaches the transfer point.

Abstract: A device for the injection of composite materials into a mould cavity (C) by general piston action comprises two, independently controlled, concentric pins (6,7) operated successively so that immediately prior to the penetration of the material into the device body (2) and its delivery into the mould (C) the central pin (6) uncovers the internal space in the outer tubular pin (7) so evacuating the air from the mould. Simultaneous axial displacement of the two pins (6,7) assures delivery into the mould. Two oblique channels (2a,2b) connect to the injection nozzle (1). They are displaced along its length, the closest to the mould (2a) being the natural feed and the furthest is connected to the vacuum pump.

Abstract: Une technique de compression-expansion consiste à utiliser un masquage spatial afin d'éviter des problèmes de parasites et/ou de distorsion introduits lors de la mémorisation ou de la transmission de signaux vidéo. Une caractéristique de codage ou de compression-extension vers l'avant de cette technique divise une image vidéo en partie distincte. Une moyenne locale (114) est calculée pour chaque partie. Pour chaque pixel dans une partie, la moyenne de cette partie est soustraite (118) et le résultat est soumis à un processus non linéaire vers l'avant (120), qui accentue les signaux vidéo proches de la moyenne locale et désaccentue les parties de signaux vidéo qui sont relativement différentes de la moyenne locale. Un signal de sortie codé est appliqué à un support (197), et, lors de son extraction du support, le signal extrait est soumis à un processus de décodage comprenant un processus de reconstitution non linéaire (146) qui est l'inverse du processus non linéaire appliqué au cours de l'étape de codage.

Title: Process for operating a gas turbine.
Inventor: WINKLER WOLFGANG
IPC: F02C6/00
Filed: 1993-07-14
Abstract: The invention pertains to a process for operating a gas turbine as part of a steam process, where the gas turbine has an air compressor (4), a combustor (3) and a turbine (5) which drives the air compressor (4). The object of the invention is to indicate a process whereby a gas turbine can be operated at up to a stoichiometric fuel/air mixture. This is achieved in that the air compressor (4) delivers at least the volume of air required for combustion and the fuel gas is cooled to the permissible turbine entry temperature by being mixed with steam that is taken from an external steam process. Alternatively, the gas turbine also works with interheating between a high-pressure turbine (9) and a low-pressure turbine (10), where the exhaust gas of the high-pressure turbine (9) is heated ahead of the high-pressure turbine (9) by means of heat transfer from the combustor gas, which then cools as a result.

Patent EP-0682824-A1 (EP)
Inventor: PFEIFFER JOHN DAVID
IPC: H02J7/00
Filed: 1993-08-27
Abstract: A battery charger and method are disclosed for charging alkaline, Ni-Cad and zinc-based batteries, particularly sizes N, AAA, AA, C and D. For batteries rated at about 1.25 volts to about 1.5 volts, the battery charger and method provide a constant charging current of between about 0.28 ma to about 1.5 ma per gram weight of the battery. A constant current circuit under control of a controller provides the constant current to the battery under charge. A reference voltage generator generates reference voltages as the battery is being charged while the controller frequently monitors the battery voltage and compares it to the reference voltage. A substantially constant current is supplied to the battery while a reference voltage greater than the battery voltage is provided. Thereafter, as the battery voltage increases, the reference voltage is incremented up to a predetermined maximum reference voltage. The controller causes the constant current circuit to terminate the supply of current to the battery when the reference voltage reaches the predetermined maximum, or when the battery voltage does not increase during charging to be greater than a first or a subsequent reference voltage during a predetermined charging time period. The controller may also cause the constant current circuit to supply from time to time a substantially constant test current to the battery which exceeds the charging current by from about 2.5 % to about 25 % for up to a predetermined testing time period, and terminate the supply of current to the battery if the test current increases by greater than a predetermined amount within the predetermined testing time period. The battery charger may at the same time charge batteries of different sizes, and includes a separate constant current circuit for each battery in the battery charger. Each battery is constinuously supplied with charging or testing current as determined by the controller, and the controller controls charging of each battery independently of the charge condition of any other battery. A separate controller may control each constant current circuit, or a microprocessor may control all of the constant current circuits.

Inventor: STERNS WILLIAM G
IPC: H01P1/208
Filed: 1994-03-26
Abstract: A two port dual bandpass microwave filter (30) consisting of "n" resonant cavities (38,42). Each cavity resonates in two independent modes at displaced frequencies so that the filter has two passbands in a desired frequency band. By orienting an incoming waveguide (48) at an angle with respect to the filter, both TE and TM modes can be excited to produce two separate passbands. The passbands may have either equal or unequal characteristics. Fine tuning of the TE and TM modes is accomplished using tuning plungers or tuning screws. The dual bandpass response of the new filter is achieved by utilizing the TE <sub>1,1,1</sub> and TM <sub>0,1,0</sub> modes in right circular cylindrical cavities, or equivalent modes in rectangular, or other cavities. These modes are orthogonal so they do not couple to each other. The cavity loaded Qs are independently adjustable, so the two passbands can have the same or different bandwidths, the same or different amplitude ripples and the same or different phase responses. The dual bandpass microwave filter provides filtering with but one set of cavity resonators rather than two. It does not require three port microwave junctions with critical path lengths. The filter is well-suited to filter the output of a single transmitter capable of operation at two differential frequencies.
