Abstract: An internal multi-band antenna and a radio device comprising such an antenna. A radiator (320) of the antenna is a conductivepart of the outer cover (COV) of a radio device or conductive coating of the cover. The radiator is electromagnetically fed by a feed element (330) which is isolated from the radiator by a relatively thin dielectric layer. The feed element is shaped so that it has, together with the other parts of the antenna, resonance frequencies in the range of at least two desired operating bands. The antenna structure further includes a parasitic tuning element (340) and a switch (SW) by which the tuning element can be coupled to the signal ground (GND) through at least two alternative reactive circuits. The tuning element is dimensioned and placed and the component values of the reactive circuits are chosen so that of two operating bands of the antenna the locations of both are displaced in a desired way when changing the state of the switch. By means of a relatively simple switch arrangement, the antenna can be made to cover the frequency ranges of four systems, and it can also be optimised for each system separately, because its operating bands only cover the range used by one system at a time.

Abstract: 1,231,122. Reverse gearing; position clutches. MAAG GEAR WHEEL & MACHINE CO. Ltd 22 Oct., 1969 [1 April, 1969], No.51806/69. Headings F2C and F2D. A ship's drive including at least one unidirectional prime-mover 1 drivingly connected to at least one output shaft 13 provided with a ship's propeller (there may be two counterrotating shafts 13, either parallel or concentric) by a reverse gearing having at least one intermediate shaft 7, 9 each for ahead and astern travel, each shaft 7, 9 having at least one positive clutch 6, 8, arranged so that when changing from ahead to astern travel (and similarly vice versa) the gearing is braked, e.g. at 14 and 15) and while stationary the reverse clutches 8 are engaged before the ahead clutches 6 are disengaged. There may be a plurality of prime movers 1, which may be of differing power, which may share some or all of the shafts 7, 9, each prime mover 1 then having an overrunning clutch. The positive clutches 6, 8, Figs. 10, 11, may each comprise an internally toothed sleeve 34 having one ring of teeth 34a slidingly engaging splines 37a integral with a pinion 4, 5, and two rings of teeth 35, 36 arranged to selectively engage rings of teeth 31, 32, 33 on the shaft 7, 9. The rings 31 . . . 33, 35, 36 have, in effect, alternate teeth removed as in Fig. 11, so that when for clutch engagement the sleeve is moved axially either the teeth 35 or the teeth 36 will be able to partially engage the teeth 32 as in Fig. 11, and on rotation being resumed, full engagement can be effected. Control of the reverse gearing may be by an hydraulic circuit, Fig. 16 for each clutch 6, 8 controlled electrically, Fig. 17. In the clutch disengaged position shown, in Fig. 16, the sleeve 34 is centralized by two pistons 41 under pressure via a line 48 causing a spool 43 to be centralized, a spool 44 being moved to the right under pressure via a line 49. A clutch engaged signal in a solenoid 46 urges the spool 40 to the left allowing fluid pressure via a restrictor 52 to slowly move the spool 43 to the right until either the teeth 35 hit the teeth 32 when the spool 44 is urged slowly to the left under pressure via a restrictor 54 or until partial engagement, as in Fig. 11 when the spool 44 is halted due to pressure in a line 55. If the teeth 32 and 35 hit, the spool 44 moves to the left when the process is repeated by spools 43 and 44 moving the other way. When the control lever is switched from forward F to reverse R a tachogenerator 16, Fig. 17, on the input shaft holds the spools 40, 40a in the forward position by contacts 61 until rotation is stopped, when the contacts 61 change over allowing relay 65 to be energized to engage the clutch 8. When this is engaged a limit switch 63 moves over to switch off the relay 46 and via contacts 60 to switch on the relay 45 to disengage the clutch 6.

Abstract: 1,250,903. Electrophoretic painting. FORD MOTOR CO. Ltd. 30 July, 1968 [7 Sept., 1967], No. 36275/68. Heading C3P. [Also in Division C7] Paint is electrodeposited on a conducting article, e.g. a zinc phosphate-treated steel sheet, from an aqueous paint dispersion comprising an essentially linear copolymer having terminal α,#-olefinic unsaturation, e.g. 2 to 4 such units per 1000 units M.W., and sufficient ionizable (e.g. at least 2 carboxyl) groups to allow dispersion, to form a copolymer film which is subsequently polymerized by ionizing radiation, e.g. by passing the water-rinsed painted article through an electron beam. The copolymer preferably has a M.W. above 250 and is formed by reaction of a first polymer containing at least 2 : hydroxyl, amino, carboxyl, anhydride, mercapto or epoxide groups per molecule with a second compound containing α,#-olefinic unsaturation, preferably di- or poly-carboxylic acid or anhydride. The paint may also comprise other monomers and/or polymers, with or without pigment and/or particulate filler. For example, a linear copolymer is prepared by reaction of an epoxy resin (formed by reaction of epichlorohydrin and bisphenol) with benzyl dimethylamine or diethanolamine, dioxane and itaconic anhydride under nitrogen; the copolymer added to water with diethylamine with or without xylene forms the dispersion.

The water is fed to the boiler from the mains via the cooling coil of condenser 8, tube 8' and device 18 (the inlet to the boiler cannot be seen for it is behind device 18). Excess water in device 18 flows out of the apparatus via side arm 19' and conduit 19. During normal operation there is an air-lock in the inverted U-tube of device 18. The distilled water flows through conduit 11 to the reservoir and, when full, a level-sensing device causes the heater and the water supply to be switched off. If the water supply should fail and the boiler overheat, switch 6 opens to switch off the heater and the water supply. When the boiler requires cleaning, valve 20 is actuated and this causes a jet of water from tube 16 to enter the open end of the U-tube in device 18 whereby the syphon operates and boiler 2 is emptied. Cleaning liquid (e.g. acid) is then passed into the boiler from funnel 21. The boiler may then be emptied as before, and may be flushed out with several changes of water. The boiler may be made of metal, plastics material or ceramics, but is preferably made of thermalshock-resistant glass. The apparatus may be used to distil liquids other than water. An organic solvent may be used to clean the boiler.
