Title: Diversity reception device
Inventor: IINUMA TOSHINORI
IPC: H04B7/08
Filed: 1995-05-15
Abstract: A diversity reception device which weights in proportion to the reception level and combines a plurality of reception signals, includes a phase demodulator for demodulating the phase of the reception signal, a converter to output the sine and cosine elements of the reception signal, a sine element adder to add up sine element of each reception signal, and a cosine element adder to add up cosine element of each reception signal. The converter fetches and outputs predetermined values on sine and cosine elements of the reception signal upon input of the reception signal's reception level and phase data that is sent from phase demodulator. Therefore, the present device does not require expensive electronic circuits and can be made of small digital circuits suitable for IC including a memory.

Filed: 1995-07-21
Abstract: An asymmetric reinforcement belt structure for a pneumatic tire is disclosed.  The reinforcing structure includes an outer belt and inner belt, each reinforced with a plurality of generally parallel cords.  The outer belt has a first portion between the centerlines of the cords and a first surface and a second portion between the centerlines of the cords and a second surface.  The first portion has a thickness T1 which is between 110% and 150% of T2.          Similarly, the inner belt has a third portion and a fourth portion, with the third portion being between the centerlines of the cords and a third surface and a the fourth portion being between the centerlines of the cords and a fourth surface.  The fourth portion has a thickness T4 which is between 50% and 90% of a thickness of the third portion T3.  Orienting the cords within the belts in this way separates them slightly more than would be so if the belts were symmetrical.  This additional separation reduces the conicity of the tire.

Title: Method for the thermal treatment of waste material, particularly refuse, and a rotary tubular furnace for applying the method
Inventor: RUEEGG HANS
IPC: F23G5/027
Filed: 1995-09-28
Abstract: A waste material, particularly refuse, is conveyed through a combustion chamber while simultaneously being mixed and is treated with a gaseous oxidizing agent.  The combustion chamber comprises a rotary tubular furnace.  The waste material is acted on by the gaseous oxidizing agent, with the volatile combustible constituents of the waste material forming flames with the oxidizing agent.  The radiation heat of the flames frees additional volatile constituents of the waste material.  The waste material freed of volatile constituents is obtained as refuse coke and the unburnt volatile constituents are obtained as combustible gas.  The thermal treatment in the rotary tubular furnace can be continued beyond the freeing of volatile substances.  Given an adequate temperature rise, the oxidic constituents of the slag formed are melted, and the latter can be obtained in the form of glass.
Patent CA-2160021-A1 (CA)
Title: Means for temporary storing of subjects
Inventor: GRAM KLAUS
IPC: B65G21/18
Filed: 1994-04-14
Abstract: A plant (1), preferably a freezer tunnel for temporary storage of items and comprising an inlet station (3) and a discharge station (2) and a conveyor (4) for carrying the items through the plant, may be provided with a buffer effect in a simple manner. The conveyor (4) loops around fixed turning rolls (9) and around displaceable turning rolls (8) positioned on a trolley (17) which can be displaced back and forth between the fixed turning rolls (9). The buffer storage is established in that a drive member (14) for the conveyor (4) is provided both at the inlet and the discharge station (2, 3). Any one of these two drive members is constructed to be operated at a speed that is different from the speed of the other drive member. As the trolley (17) is in a freely displaceable position, a difference in speed will mean that the conveyor section (24) between the trolley (17) and the fixed turning rolls at one side of the plant may be enlarged and reduced. The conveyor section (24) will run between the two stations without being loaded with items for storage.

A fan within the heat exchanger circulates room air in a flow path from the room being heated into the duct manifold inlets, through a first duct and into the heat exchanger, from the heat exchanger and through a second duct, and out through the duct manifold outlets. The fireplace also includes a raiseable hearth overlaying an opening accessing the heat exchanger fan. The fuel grate of the fireplace includes a connector connecting with the hearth that allows the grate to be utilized as a handle to raise the hearth.

Filed: 1995-02-21
Abstract: A method for fabricating high-resolution, biocompatible electrodes (11) is disclosed, allowing production of an electrochemical sensor which is capable of precise analyte concentration determination on a very small sample size. Electrically conducting material (3) is affixed to a first insulating substrate (4). A second insulating substrate (5) is then affixed to the electrically conducting material (3) and patterned using photolithography to define an electrode area (8). Alternatively, the electrically conducting material (3) may be screen printed directly onto a standard printed circuit board substrate (4) in the case of a counter or reference electrode. In either case, the substrate may be rigid or flexible. When the electrodes produced in accordance with the present invention are then used in an electrochemical sensor which includes a reagent, the small and highly-defined electrode areas (8,9) permit highly-accurate electrochemical  analyte measurements to be performed on very small sample sizes.
