Abstract: 351,494. Gas-producers. LAPIERRE, T. A., Cloverdale, British Columbia, Canada. March 26, 1930, No. 9656. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 27, 1930.] [Classes 51 (i) and 55 (i).] In a gas-producer comprising a primary combustion chamber beneath an inclined preliminary distillation chamber, the latter is heated alternatively by hot gases from the former discharging into a secondary combustion chamber which is separated from the distillation chamber by an inclined wall, or by burning the gases of distillation in the secondary chamber. The distillation chamber is composed of a number of retorts through which the fuel flows progressively and from each of which gaseous or liquid fractions are collected. Carbonaceous material passes from the hopper 44 into longitudinal troughs 38 in the base of the distillation chamber which is comprised by a series of retorts 39 .. 42, where it is disturbed by agitators 69. The material flows from the distillation chamber through the fuel passage 21 on to a stepped grate 7 in the primary combustion chamber 1. The carbon monoxide resulting from the combustion passes to the secondary chamber 26 for heating the distillation chamber. The cooled gas is withdrawn through a pipe 33 and passes to the scrubber 35. Distillation gases from the retorts pass to the condenser 50 and then to the scrubber 35 and part or whole may be supplied to the burner 56 for heating the secondary chamber. Air and moisture are withdrawn from the uppermost retort and liquid fractions from each of the succeeding retorts. The grate may be raised or lowered by rotation of arms 17 which are slotted to engage pins carried by the connecting plates joining the grate bars together. The arms 17 are operated through a worm drive from a handoperated shaft extending outside the combustion chamber.

IPC: C07C61/04
Filed: 1986-07-31
Abstract: HUT045476 In order to obtain optical isomers of trans-chrysanthemumic-acid, an enantiomer of 3-40% optical purity is agitated in an organic solvent at a temp. between -10 and +30 deg.C. The resulting crystalline trans-chrysanthemumic acid is removed and the optically active fraction is extracted from the liq. phase. If needed, the process is repeated once or a number of times. Conversely, an enantiomer mixt. of at least 40% optical purity is allowed to stand between -15 deg.C and 35 deg.C and the fluid fraction of greater optical purity is sepd. from the solid crystalline fraction of lower optical purity. This process can be repeated one or more times, using the melt as the starting point. The solid crystalline fraction is reagitated with the aid of an organic solvent in order to separate the racemic and optically pure parts.

Title: Structure of grounding conductor for signal measuring device
Inventor: CHIYOJIMA TOSHIO
IPC: G01R1/073
Filed: 1988-01-08
Abstract: PURPOSE:To conduct signal measurement with little error in measurement, by making a sheet-shaped conductor means windable and by increasing the width thereof gradually from a narrowed end on the leading side thereof. CONSTITUTION:The leading length of a sheet-shaped conductor means 30 can be minimized in relation to a signal detecting position of a measuring probe 22 of a signal measurer 10, since the sheet-shaped conductor means 30 is so wound that it can be pulled out. Therefore, signal detection can be conducted in a state wherein the impedance of the sheet-shaped conductor means 30 is minimized. In addition, the width of the sheet-shaped conductor means 30 increases gradually as it is pulled out from a narrowed end 32 thereof to begin with. Therefore an increase in the impedance with the pulling-out of the sheet- shaped conductor means can be reduced to be small.

Abstract: PROBLEM TO BE SOLVED: To decrease the number of the elements of the input/output stage of a wavelength multiplex highway switch. SOLUTION: Six optical multiplex lines of wavelengths λ5 and λ8 are connected to the wavelength multiplex optical switch 10, which performs line switching among channels. Multi-input type wavelength demultiplexer multiplexers 13 and 14 divide the six lines into three lines 11 and 12, and input multiplexed signals λ5 and λ8 and output demultiplexed signals λ5 and λ8 from three demultiplexing output ports corresponding to the lines. The demultiplexed signals are inputted to matrix switches 22 and 23 through links 25-28, switched by the lines, and inputted to three demultiplexing input ports of the multi-input wavelength demultiplexers 13 and 14 through links 29-32. The multi-input wavelength demultiplexer multiplexers 13 and 14 multiplex the demultiplexed signals λ5 and λ8 and output them to optical multiplex lines 11 and 12.  Thus, the multi-input wavelength demultiplexer multiplexers are provided and then 12 demultiplexing and multiplexing elements which are conventionally needed for the six-line input/output stage can be reduced to two.

Title: Laminate and electromagnetic-wave shield using the same
Inventor: FUKUDA SHIN
IPC: H05K9/00
Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To obtain a laminate which can be used suitably for an electromagnetic-wave shield by a method, wherein the laminated body is formed in such a way that a metal layer which has a light transmitting part on one main face of a transparent polymer film and whose thickness is in a range of a specific value is formed on the film, and the open area ratio and the sheet resistance of the metal layer are set in the range of a specific values. SOLUTION: It is preferable that a transparent polymer film 60 have a proper heat resistant property and a proper light transmitting property. For this purpose, a metal layer is formed on a main face. The thickness of the metal layer is preferably 200 to 2,000 nm. When the thickness is larger than this value, time is taken for etching operation. When the thickness is smaller, an electromagnetic-wave shielding ability becomes poor in. The open area ratio of a light transmitting part is preferably set at 60 to 95%. The shape of the light transmitting part is formed preferably, in such a way that uniform equilateral triangles are arranged unformly inside a face. The substantial sheet resistance of the metal layer is preferably at 0.05 to 0.5 Ω/(square).  When its value is smaller than this value, the film thickness becomes too large, and an opening part cannot be formed sufficient large. When the value is larger, a sufficient electromagnetic-wave shielding capability cannot be obtained.
