Abstract: 1,254,694. Waveguides. PLESSEY CO. Ltd. 10 Jan., 1969 [12 Jan., 1968], No. 1976/68. Heading H1W. A resonant line is provided with a core of ferrite and means for applying to the core orthogonal bias magnetic fields one of which coincides with the predominant direction of the R.F. magnetic field, whilst the other is at rightangles to the R.F. field. The first bias field produces a high, and the second a low permeability in the ferrite core, whereby the line may be tuned by varying the relative magnitudes of the two fields. If the fields are sufficient to saturate the ferrite, the tuning is independent of the absolute magnitude of each field. In the coaxial resonator shown in Fig. 3, a tubular inner conductor 16 is surrounded by a core composed of a series of ferrite bushes 18. These are magnetically biased in a circumferential direction by windings 21 which pass through the centre of the inner conductor 16 and around the outside of the outer conductor 19. The core is also subject to an axial field produced by a winding 22 around the outer conductor. The windings are connected to D.C. terminals 24 and R.F. terminal 25. In order to prevent R.F. coupling to the windings 21, the R.F. input may be applied to the centre of two quarter-wavelength lines. Temperature compensation may be obtained by using barium ferrite for the bushes 18. In a modification (Figs. 1, 2, not shown) the resonator consists of a triplate strip line having a narrow central strip conductor separated from relatively wide outer conductors by strips of ferrite of the same width as the outer conductors. Thin layers of P.T.F.E. are arranged between the ferrite strips on either side of the central conductor, and between the ferrite strips and the outer conductors. The line is arranged between four polepieces which produce orthogonal fields transverse to the axis of the line and tuning is effected by selective energization of the fields.

[Also in Division B8] A plurality of article wrapping support plates, each having its own wrapping film source, are of different sizes and movable from an article receiving position to an inoperative position. Each film comprises two opposed webs, one fed over a plate and one fed under a plate. In the embodiment, reels 19, 20 supply longitudinally folded film of different widths to support plates 17, 18 respectively of corresponding width. A lip 21 on each plate keeps the layers of the film apart. Laundry, received by an operator from a conveyor 12, is placed on one of the plates between film of the most suitable width. If this is the lower plate, the upper plate is hinged about a pivot 22 to a substantially vertical inoperative position. The operator then draws the article and wrapping along to a station 14 where the side edges of the film are sealed, and the trailing edge sealed and severed, thus forming a sealed front edge for a suceeding package. Conveyor 15 carries the package to an oven for heat shrinking. The drawing off of the film from the reel is power assisted through driver rollers 25, 26 which are actuated when a slidable guide roller 28 disengages a switch 35 after an initial movement of the film by the operator. The plate 17 may be spring biased to its horizontal or vertical position. A plurality of plates may be used corresponding to the number of different widths of film. The bottom plate 18 may also pivot and the plates may be slidable in, and out of position. Film may be drawn from a reel in a single layer to be folded during the wrapping process or each plate may be supplied with separate upper and lower films.

Title: Improvements in the biological purification of waste water
IPC: C02F3/34
Filed: 1928-01-25
Abstract: 307,587. Wade, H., (Aktieselskabet Dansk Gaerings Industrie). Jan. 25, 1928. Bacteriological processes.-The purification of industrial waste water is carried out in stages, use being made at each successive stage of different micro-organisms, decomposing special groups of polluting matter and preferably derived from pure cultures. Micro-organisms of the following groups may be employed .-(1) Proteolytic ammonia-forming, nitrifying and de-nitrifying bacteria, (2) Yeasts and hyphomycetes decomposing fat, (3) Bacteria or fungi dissolving starch or decomposing dextrin and sugar, (4) Bacteria decomposing cellulose or pectin. It is advantageous to make use of bacteria which have been brought into or tend to take the zoogloea state. The process is carried out in a series of treatment tanks alternating with settling tanks. The temperature and hydrogen ion concentration of the liquid in each treatment tank is adjusted to suit the particular micro-organisms at work therein. According to one example, starch present in the waste water is first decomposed into glucose or maltose by means of aspergillus oryzae, bacillus subtilis, or bacillus mesentericus; secondly, sugar matter is decomposed by treatment with yeast, next, albumen and urea are broken down by means of bacillus putrificus or vulgaris and the products converted into ammonia by bacillus mycoides, formic acid is broken up by means of bacterium formicicum, and finally the ammonia salts are oxidized by treatment with cultures of nitrosomonas and nitrobacter. The biological treatment may be combined with other treatment; for example, a sludge obtained by treating waste water with aluminium hydroxide may be inoculated with a bacteria culture and agitated with the waste liquid or filters of sand or coke inoculated with pure bacteria cultures may be used. Waste waters of different constitution are preferably kept separate for treatment, and special classes of matter may be removed from the waste water for separate treatment. Specification 284,267 is referred to.

Title: Improved compression ignition engine fuels
IPC: C10L1/23
Filed: 1940-02-12
Abstract: 543,669. Diesel fuel. STANDARD OIL DEVELOPMENT CO. Feb. 12, 1940, No. 2701. Convention date, April 4, 1939. [Class 91] [Also in Group IV] A small amount of a nitroalkyl nitrate is added to a diesel fuel to improve its ignition qualities. The nitrate may comprise a mononitroalkyl mononitrate, preferably having 3 to 8 carbon atoms, or a mononitroalkylene dinitrate, preferably containing at least 5 carbon atoms. All are soluble in diesel fuels with the exception of. the solid dinitrate of 2-methyl-2-nitro-1:3- propanediol and this may be held in solution by a liquid nitrate. The nitrates may contain a chlorine substituent, provided at least 5 carbon atoms are present. Tests are described demonstrating the effectiveness of the addition of the mononitrates of 2-methyl-2-nitro-1-butanol, 2- methyl-2-nitro-1-propanol, 2-nitro-1-pentanol and 2-nitro-1-butanol, and of the dinitrates of 2-ethyl-2-nitro-1:3-propanediol and 2-methyl- 2-nitro-1 : 3-propanediol; also of the addition of a mixture of the dinitrate of 2-methyl-2-nitro- 1:3-propanediol with the nitrate of 2-methyl-2- nitro-1-propanol. The Specification as open to inspection under Sect. 91 also describes the use of nitroalkyl nitrates which may contain other substituents than chlorine, e.g. a thio group or an additional nitro or nitrate group, the compound then containing at least 5 carbon atoms. This subjectmatter does not appear in the Specification as accepted. Nitroalkyl nitrates are prepared by condensing a nitroparaffin with an aldehyde and esterifying the resulting nitro-alcohol with nitric acid. Thus, 2-nitrobutane is condensed with formaldehyde in the presence of sodium hydroxide to give 2-methyl-2-nitro-1-butanol, which is then converted into the nitrate by treatment with a mixture of nitric and sulphuric acids at a low temperature, e.g. below -5C. Similarly, primary and secondary nitroparaffins can be condensed with other aliphatic aldehydes or with a mixture of formaldehyde and another aliphatic aldehyde to give both monohydric and dihydric nitro-alcohols, which are then converted into their mono- or dinitrates.
