Title: Improvements relating to ultra-high frequency aerials
Inventor: MILNE KENNETH
IPC: H01Q5/45
Filed: 1954-03-23
Abstract: 758,957. Directive radio systems. BRITISH THOMSON-HOUSTON CO., Ltd. March 22, 1955 [March 23, 1954], No. 8483/54. Class 40 (7). An aerial system comprises a pair of primary elements located adjacent to each other and capable of transmitting and/or receiving electromagnetic energy of different wavelengths and having mutually perpendicular polarizations together with two reflectors, one designed to co-operate with each primary element, the reflectors being located one behind the other and the one nearest the elements being constructed to reflect energy of one polarization and pass energy of the other polarization used. The system may be used in a duplex signalling or radar arrangement and provides a smaller and more readily movable device for such arrangements where operation on two different wave. lengths is required than can be achieved by the use of two separate aerials. The reflectors may be of the " cheese " type or of paraboloidal or other form and it is desirable that they should be designed for offset feeding so that the primary elements are not in the path of the emergent beams. The rear reflector may conveniently be of sheet-metal construction whilst the front one may be a grid of parallel spaced wires. It is pointed out that for the best effect it is desirable to use a large ratio of focal length to aperture for the reflectors so that the polarization of the energy incident on the wire grid is everywhere substantially parallel or perpendicular, as the case may be, to the wires. The aerial system may be constructed as a unitary structure which may be rotated or oscillated to scan the beams. In some cases the reflectors may be fixed and the radiators moved independently.

Title: Process for the preparation of substituted aminocarboxylic acid amides
Filed: 1957-03-15
Abstract: The invention comprises a process for the preparation of substituted aminocarboxylic acid amides soluble or dispersible in water or of salts thereof, which consists in preparing a mono-amine salt from an aliphatic, cycloaliphatic or aliphatic-aromatic primary or secondary amine which contains in the molecule at least one lipophilic hydrocarbon residue of at least six carbon atoms, which residue may be interrupted by hetero atoms or may contain substituents, and a di- or poly-basic aminocarboxylic acid, removing the elements of water from the said amine salt and so obtaining a substituted aminocarboxylic acid amide, and, if desired, converting said amide into a salt thereof.  The elements of water may be removed by dry-heating at above 100 DEG  C., preferably at 180-200 DEG  C., and may be effected under reduced pressure and/or in a current of nitrogen.  Suitable amines are hexylamine, dodecylamine, oleylamine, octadecylamine, cyclohexylamine, alkylcyclohexyl primary amines (alkyl residues C3-C12), naphthenylamines, alkylphenyl primary amines (alkyl residues C3-C18), and amine mixtures such as coconut oil amine; also secondary amines such as methyloleylamine, ethyldodecylamine and didodecylamine.  Suitable aminocarboxylic acids include nitrilotriacetic acid, ethylenediamine tetraacetic acid, hydroxyalkyliminodiacetic acids such as hydroxyethyliminodiacetic acid, and hydroxyethyl-ethylenediamine triacetic acid.  The formation of the amine salts may be effected in aqueous solution or in organic solvents, or by melting the starting components together.  The free carboxyl groups of the final products may be converted into salt groups in known manner, suitable salt-forming components being metals, such as sodium, potassium, magnesium, calcium and aluminium, ammonium and organic bases such as alkanolamines, pyridine and cyclohexylamine.  In examples the reactants are (1) n-dodecylamine and hydroxythyliminodiacetic acid; (2) coconut oil amine and hydroxyethylimino diacetic acid; (3) dodecylamine and nitrolotriacetic acid; and (4) coconut oil amine and nitrilotriacetic acid, the sodium salts of the final products being prepared in each case.

Filed: 1973-02-23
Abstract: 1426762 Buttonhole sewing G TOLLE 23 Feb 1973 [8 April 1972] 8914/73 Heading D1G In a buttonhole sewing machine a first shaft 110 carrying an eccentric driver 100 for moving the needle laterally is carried in a bearing 111 supported, eccentrically of the axis A of shaft 110 by an amount exceeding that of the driver, in a second shaft 112, the first shaft being rotated continuously to produce the narrow seams 115 at the edges of the buttonhole and periodically operated drive mechanism 177, 186 is provided to rotate the second shaft 112 with shaft 110 to allow the combined eccentricities to produce the barring seam (118 Fig. 9C not shown). The machine has the work clamp 40 disclosed in Specification 1425184 and the movements thereof control a lever 67 associated with the cam 88 and worm wheel 89. The mechanism connecting driver 100 to the needle gate is that disclosed in Specification 1426761. The eccentricity of bearing 111 in shaft 112 is variable, by rotation of an intermediate member (113 Fig. 7 not shown), to adjust the distance between the side seams 115. The shaft 112 is mounted in a bearing 132 disposed in a sleeve 130 secured to the frame. A one-way clutch 136 is disposed between the sleeve and the shaft 112. The shaft 110 is rotated continuously from the mainshaft 20 by a belt and pulley drive 177, 186, 187. A clutch driving member 182 secured to the pulley 177 is engaged, when appropriate by a driven member 147 to drive the second shaft 112 with shaft 110 to produce barring stitches, while at other times the clutch is disengaged and the second shaft held in one of two diametrically opposite positions to sew the appropriate side seam. To achieve this a worm wheel 156 is engaged with a sleeve 142 supporting the driven clutch member 146 and slidable along shaft 110. When either finger 82 or 83 on control lever 67 moved by the work clamp, engages a projection 86 or 87 on stop cam 88 the worm 89 is stopped and continued rotation of worm wheel 156 moves the latter to the left parting the clutch members which however continue to rotate together until lug 185 on one disengages block 149 on the other. The shaft 112 then no longer rotates being held in a defined position, selected by the position of wheel 89 relative to cam 88 for one position and by the movable stop 83 on lever 67 for the other, to form the side seams. When cam 88 is released by lever 67 the worm moves rightwards to allow the clutch members to engage in a unique angular relationship achieved by the shape of the mating faces.

Abstract: 624,905. Thermal switches; protective cut-out arrangements. TAYLOR, E. H. April 5, 1947, No. 9236. [Class 38(v)] A controlled circuit 10 comprising a load of low priority, e.g., a water heater, is switched in or out in accordance with the total current taken by a controlling circuit 12, of high priority, e.g., a cooker, and the circuit 10, or the current taken by circuit 12 alone..A snap-acting bimetal plate 17, preferably that described in Specification 600,055, is adjustably clamped by nuts 14 and pillars 7, so that the total current of circuits 10 and 12 flows upwards through the outer legs of the plate and down the centre leg 18, thereby heating the plate, the central leg being connected through a pig-tail 22 to circuit 12, and through a contact 19 and co-operating contact (not shown), to circuit 10. At a predetermined current, the plate 17 snaps over-centre and cuts out circuit 10, leaving circuit 12 energized. In Fig. 5 (not shown), the circuit 10 is controlled by the current in circuit 12 alone, and in Figs. 6, 7, (not shown), the circuits 10, 12, are made independent of each other by insulating the contact 19 from leg 18. Several circuits 45, 48, 51 (Fig. 8), of varying priority, may be controlled by several plates 40, 41, connected in series by flexible conductors 46, 50, so that plate 40 carries the total current, and plate 41 the current taken by circuits. 48, 51, the circuit 45 thereby being cut-out first. As shown in Fig. 9, two switches may be prevented from being on at the same time by inserting a ball 56 in a hole 55 in a wall 54 and between the central limbs 57, 58 of the two bimetal plates 52, 53. The plates may be heated by heating coils or by the flexible conductors, and the relatively fixed contacts may be mounted on bimetal strips to provide ambient temperature compensation.
