Filed: 1924-08-18
Abstract: 229,944. British Thomson-Houston Co., Ltd., (General Electric Co.). Aug. 18. 1924. Selective distant control systems.-A faulty section of an interconnected network supplied from a number of substations is isolated by supplying to the faulty section a superimposed voltage, of a particular frequency, to which relays selectively respond to isolate only the faulty section. As shown applied to a direct-current network consisting of three districts 1, 2, 3 supplied by three interconnected line sections 4, 5, 6 with interconnecting switches 13 - - 18, district 1 is supplied from substations 19 and 25, district 2 from substations 19, 25 and 36, and district 3-from substations 25. 36. On the bus-bars of each of the substations, a different frequency may be superimposed from the A.C. generators 48, 49, 50. A fault occurring on a section, at 74 for example, is indicated by the increased current taken by that section, and, in order to isolate the section completely, the frequency from the generator 49 is switched on to the bus-bars of the faulty sections and this frequency causes the opening of all the frequency-responsive switches 13 - - 18 together with the switches 28, 31, 40 and 43 in the feeders 30, 27, 42, 39. The switches have each two windings, for example 75 and 58 for the switches 28, responsive to different frequencies. Additional closing windings also frequency-responsive may be used so that the switches may be selectively closed from the central station. If the fault occurs on section 1, switches 28 and 13 - - 15 are opened to isolate that section. Specification 10822/14, [Class 38 (v), Electric switches &c.], is referred to.

Abstract: 1522278 Cultivation of Lentinus edodes KAO SOAP CO Ltd 12 May 1977 [24 May 1976] 20003/77 Heading C6F A method of cultivating the fungus Lentinus edodes to produce fruit bodies involves inoculating a sterilized bed of an artificial granular or fibrous culture medium with spores of the fungus, cultivating the bed e.g. at a temperature of about 25‹C for a total of 40 to 70 days to generate hyphae on the surface of the bed, applying separate small pieces 10, Fig. 4, of an air-permeable inert coating material (or a single sheet having cut-out areas) to localized areas of the surface of the bed before the hyphae become brown so that these areas are covered by the film to prevent ambient air from directly contacting the areas while permitting air to permeate through the film into contact with the areas, continuing the cultivation of the bed under fungus-growing conditions to cause browning of exposed hyphae while the hyphae directly below the pieces of coating material remain white, and then subjecting the bed to fungus-growing conditions effective to form fruit bodies, which grow from the hyphae below the pieces of coating material e.g. a temperature of 15‹ to 20‹C for 6 to 9 days. The culture medium may contain sawdust, potato starch dregs, bagasse, rice hulls, rice bran or wheat bran. The coating material is typically a synthetic resin film of polyethylene, polypropylene, polyvinyl chloride, polystyrene or polycarbonate having a thickness of 20 to 200Á. Paper and regenerated cellulose are stated to be unsuitable because they are decomposed by the hyphae. The coating material may be applied to the bed either before inoculation or within 20 days after inoculation. The localized areas preferably have at least one dimension no larger than 3 cm. The culture vat may have a lid of 30Á polypropylene film.

Abstract: 407,863. Capacitance measurements. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. July 18, 1933, No. 20273. Convention date, July 19, 1932. [Class 37.] A device for measuring or comparing impedances, particularly capacities, comprises two fixed impedances C1, C2, Fig. 2, connected in a bridge with the impedances Z1, Z2 to be compared, a measuring instrument V connected across one diagonal of the bridge, a highfrequency generator E connected across the other diagonal, and a low-frequency transformer for feeding the generator, the secondary winding of the transformer being placed in a casing 3 to screen it from the primary winding. In the arrangement shown in Fig. 2, the whole apparatus is placed in an outer casing 1, which may be earthed and is connected to the point F between the impedances to be compared. The generator E may also be mounted within a screening casing 4, and the fixed capacities C1, C2 may likewise be screened. By means of these screens, if desired with the aid of additional condensers C6, C7 connected between the casing 1 and the generator terminals, the parasitic capacities of the bridge are compensated. In a modified arrangement, Fig. 3, a screened change-over switch is provided between the points A, B of the bridge and the external terminals X, Y, and the condenser C2 is replaced by three condensers C3-C5 as shown. The parasitic impedances between the points A, F and B, F of the bridge are represented by C6 and C7 ; if C6 is the larger, a small variable condenser C8 is connected in parallel with C7 and adjusted to equalize the parasitic impedances. The condenser C5 is so adjusted that C3 + C5= C1 ; any inequality between the capacities to be compared is then measured by adjusting C4. In another arrangement, Fig. 4, the generator E and change-over switch are mounted in a casing 10 which also contains the secondary winding of the transformer, this casing being mounted within a larger casing 11 containing the condensers C1, C2. In a further modification, Fig. 5 (not shown) the inner casing is made in two parts insulated from each other, the capacities between these parts and the outer casing serving for the fixed condensers C1, C2.
