Title: Method for controlling the firing rate of combustion installations
Inventor: MARTIN JOHANNES JOSEF EDMUND
IPC: F23B90/00
Filed: 1999-05-03
Granted: 2004-07-06
Abstract: In order to carry out the method for controlling the firing rate of the combustion installation, the fire grate (1) is equipped with a plurality of undergrate zones (7.1 to 7.5). In order to determine the control signal, the undergrate zone (for example 7.2) at the beginning of the main combustion zone is equipped with the corresponding measurement devices, namely a temperature sensor (17) and a pressure sensor (19) and the associated air supply line (for example 8.2) is equipped with an airflow measuring device (18).      A further pressure sensor (20) is provided in the furnace space (3) so that the static pressure difference between the undergrate zone and the furnace space can be determined. The measured values from this measurement equipment are supplied to a central computer ZR which outputs, if necessary taking account of a flow coefficient a, a control signal R to the control device RE, which is connected to the various setting devices (21 to 24), in order to influence the stoking speed of the grate, the fuel deposition rate, the slag removal rate and, if necessary, the airflow to the individual undergrate zones.

The board supporting structure has a shoe mounting surface extending generally orthogonally from the first shaft. The board supporting structure also has a radially outer-most rim, radially outer-most relative to the first shaft. The rim is generally circular and generally circumferentially contiguous so as to form a board supporting surface around the rim. An elongate shoe has first and second ends. A board supporting heel is mounted on the shoe. The shoe is pivotally mounted at the first end of the shoe to the shoe mounting surface. A cam follower is mounted to the shoe at generally the second end of the shoe so as to protrude from the shoe away from the shoe mounting surface.

Abstract: A magnetic code reading device and magnetic code reading method in an ATM or the like which after detecting a readout magnetic waveform including jitter, performs necessary transaction processing without performing uniform error processing in a predetermined case. The device comprises a magnetic head having a magnetic sensor for writing and reading magnetic code onto/from a magnetic recording medium, a timing disk for generating a timing pulse in correspondence with a moving distance of the magnetic head, and a controller for controlling the magnetic head and the timing disk, wherein upon reading of magnetic code on the magnetic recording medium where predetermined information is written in correspondence with the timing pulse, if jitter appears at relatively fixed intervals, corresponding to a rotational period of the timing disk, in a series of readout magnetic waveforms detected by the magnetic sensor, the controller recognizes the magnetic code based on the series of readout magnetic waveforms including the jitter, while if jitter is not related to the rotational period of the timing disk, the controller performs reading error processing.

Title: Integrally asymmetrical polyolefin membrane for gas transfer
Inventor: MULLER MARCUS OSKAR
IPC: B01D69/02
Filed: 1998-07-16
Granted: 2007-05-22
Abstract: Process for producing hydrophobic polyolefinic membranes for gas exchange via thermally induced liquid-liquid phase separation.    A solution of at least one polyolefin in a solvent system with a viscosity less than 60 mPa s, consisting of a compound A  and a compound B, is extruded to form a shaped object. The compound A is a solvent and compound B preferably a non-solvent of the polymer, and the boiling point of compound A is at least 50°C higher than that of compound B. After the shaped object leaves the die, at least one surface thereof is subjected to an atmosphere promoting evaporation of compound B, and the shaped object is subsequently cooled until the phase separation and solidification of the high-polymer-content phase take place.  The integrally asymmetrical membrane producible in this manner has a porosity of greater than 50% to 75% by volume, a sponge-like, open-pored, microporous support layer without macrovoids and on average isotropic pores, and at least one separation layer with pores <100 nm, if any.

Abstract: The purpose of the present invention is to provide a datagram transfer network that can operate stably by avoiding a state of congestion collapse by utilizing information derived from evaluating the impact of datagrams on the operation of the network. To achieve this objective, the results of evaluation is expressed as a preference value related to datagrams, and are inserted in the header in each datagram so that the datagrams are processed by an approach other than the methods based on arrival sequence of datagrams, when derived to the destination indicated in the header. In this approach, forwarding of datagrams is controlled by priority order derived from the preference value which reflects traffic information obtained by a traffic monitoring equipment.

Abstract: A fiber reinforced composite wood flooring is designed particularly for use in van-type truck trailers which experience adverse operating conditions due to heavy lift truck traffic on the top side and water spray during rainy periods on the bottom side. The composite wood flooring comprises edge-glued laminated wood which is underlaid with a thin layer of fiber reinforced plastic. The top surface of the composite wood floor is the same as that of a conventional laminated wood floor. The fiber reinforced plastic underlay is composed of glass and/or carbon fibers embedded in a polymeric resin such as epoxy, phenolic, vinyl ester, polypropylene or polyamide resin. The fiber reinforcement is designed to enhance the mechanical properties of the flooring in the longitudinal and transverse directions of the floor. The fiber reinforced plastic improves the fatigue resistance of the composite wood flooring and prevents water leakage into the trailer through the floor boards.

Title: Double-tube type heat exchanger and refrigerating machine using the heat exchanger
Inventor: YONEDA YUJI
IPC: F25B40/00
Filed: 1999-07-22
Granted: 2004-04-27
Abstract: A double-tube type heat exchanger has a restriction hole, formed on an inner tube, through which a refrigerant introduced into an outer tube is introduced into the inner tube while the refrigerant expands. Therefore, a part of the refrigerant introduced into the outer tube can be introduced into the inner tube from the restriction hole while the refrigerant expands. That is, the restriction hole formed on the inner tube serves as an expansion mechanism of a bypass flow. Therefore, this double-tube type heat exchanger allows an injection circuit or a super-cooling circuit to be compactly and inexpensively constructed.

Abstract: This invention relates to a method and apparatus for reducing adjacent channel power in wireless communication systems. More particularly, the present invention is directed to a system for digitally and adaptively pre-distorting a signal that includes applying a correction to the signal before it is applied to the input of an amplifier such that the correction is equal and opposite to anticipated distortion produced by the amplifier. Thus, the correction and the amplifier distortion cancel one another resulting in a system with an overall linear transfer characteristic. In these circumstances, the adjacent channel power is desirably reduced.
