Title: Manufacture of new highly polymeric linear esters and the production of filaments, fibres and the like therefrom
IPC: C08G63/189
Filed: 1945-11-23
Abstract: Alkyd resins are prepared by heating, preferably in the absence of oxygen (e.g. in a stream of nitrogen), 1 : 5-, 2 : 6-, or 2 : 7-naphthalene dicarboxylic acid or an ester-forming derivative thereof with ethylene or tri-, tetra-, penta-, or hexa-methylene under conditions such that during the later stages of the reaction volatile by-products and excess of glycol are p  removed and continuing the heating until filaments formed from the melted resin can be permanently extended by cold-drawing to useful fibres. Suitable derivatives are esters and half-esters such as low alkyl (e.g. methyl, ethyl, propyl, butyl, amyl, hexyl and heptyl), cycloalkyl, and aryl (e.g. phenyl) esters; acid halides; and ammonium or amine salts.  When the acid itself is used a large excess (e.g. 4 to 5 molar proportions) and when an ester is used about 1 1/2 molar proportions of glycol is preferably used.  When a dihalide is used a diluent such as an inert organic liquid and a base, e.g. a tertiary organic base such as pyridine, N-methyl-piperidine, N-dimethylaniline or N-diethylaniline, are preferably present.  Specified ester-interchange catalysts which may be present are lithium, sodium and potassium or their carbonates or borates, calcium, beryllium, magnesium or its oxide, the alcoholates (e.g. methylates and ethylates) or glycolates of the foregoing, zinc, cadmium, aluminium, chromium, molybdenum, manganese, iron, cobalt, nickel, copper, silver, mercury, tin, lead, bismuth, antimony, platinum and palladium.  Filaments extruded or spun from the molten or re-melted resin may be cold-drawn to useful fibres and the resin may also be used for films, mouldings, hot-melt coatings, adhesives, e.g. for bonding laminated fabrics such as doubled fabric collars, plasticizers, and binders for coating compositions.  In examples: (1) methyl naphthalene-1 : 5-dicarboxylate; (2) methyl naphthalene-2 : 6-dicarboxylate; (3) methyl naphthalene-2 : 7-dicarboxylate; (5) naphthalene-2 : 6-dicarboxylic acid are heated with ethylene glycol in the presence of lithium and magnesium in a stream of nitrogen; (4) methyl naphthalene-2 : 6 - dicarboxylate is heated with hexamethylene glycol under similar conditions.

Filed: 1926-12-14
Abstract: 285,200. Smith & Sons (Motor Accessories), Ltd. S., Miller, F. W., and Miller, F. Dec. 14, 1926. Thermal switches for use -in connection with electric cigar and like lighters comprise a thermostatically - controlled switch or make-andbreak device adapted to be included in the lighter circuit, thus preventing the resistance wire or filament, from being burnt out if the circuit is closed too long. Fig. 1 shows a form suitable for use with an existing lighter and comprising a main bimetallic strip 1 and a compensating strip 2 for allowing for external heating influences, each strip carrying a contact as at 8, 9. A light flexible bowspring 10 is riveted or otherwise connected to the strip 2 and to a terminal strip 11 and assists normally to maintain the contacts in engagement. When the lighter circuit is closed, current flows from terminal 7 through the strip 1, contacts, and spring 10 to the terminal 12, and the strip 1 is arranged to break circuit before the fusing point of the resistance is reached. The interval between breaking and making the circuit can be arranged so as either to give a uniform glow or to cause the lighter alternately to glow and cool. A cover 13 may be provided. The strip 1 may alternatively be arranged to be heated by radiation, in which case the strip 2 will have a different, thermal characteristic. In Fig. 4 a combined lighter and thermostat is shown, the strip 1 being connected to a contact 18 on a support 17, whereas the contact on the strip 2 is connected to a terminal through a strip 20. The other terminal connects with a flange 23 engaging a ring 24 on the detachable part 25 carrying the resistance wire 26. This wire is connected to a stud 27 engaging a contact 28 on the switch arm 19 which carries a contact 29 adapted, when the arm 19 is depressed, to engage the contact 18 and close the circuit. The compensating strip may be dispensed with.

Abstract: 926,728. Nuclear fuel elements. ATOMIC POWER CONSTRUCTIONS Ltd. Sept. 5, 1961 [Sept. 14, 1960], No. 31730/60. Class 39 (4). [Also in Group XIII] A nuclear reactor fuel element has a protective sheath I with a heat transfer surface comprising an even number of longitudinallyextending zones of helical fins, such as zones 3, 4 and 5, the pitch of the helical fins in each zone being of the opposite hand to that in the adjacent zones, and longitudinal bow-restrain- - ing members, such as radially-extending fins 6, are provided at the junctions of the longitudinally-extending zones. Two such fuel elements are shown in Fig. 2, assembled in a channel 16 in a graphite moderator structure 17. The two elements have conical end-locating members 11, 12, the member 12 having three arms 13 which locate the elements centrally in the channel 16. The fins 6 do not reach completely to the wall of the channel 16, small gaps 18 being left to allow ease of movement of the elements in the channel 16 during refluelling. The curved ends 6<SP>1</SP> of each fin 6 also assist in this direction. Bowing of the elements is first resisted by the inherent strength of the fins 6 and when this is inadequate, the initial movement of the fins closes the gaps 18 and they come to rest on the channel wall which fortifies them against further bowing. The arrangement of the helical fins results in the fins 6 being subjected to approximately equal and opposite bending forces from the coolant.

Abstract: 1,117,885. Aerials. TOKYO KEIKI SEIZOSHO, KK. 15 July, 1966 [17 July, 1965], No. 31842/66. Heading H4A. [Also in Division B5] A spherical Luneberg type radio lens of radius r 2  (Fig. 7) comprises a central homogeneous core 6 having a radius r 1  which exceeds 0À4r 2 , and a number of outer layers, the dielectric constant of a layer with a mean radius r approximating to the value The dielectric constant of the core 6 is chosen so that there is minimum variation from equiphase over a tangent plane F with illumination at a point P which is diametrically opposite, and formulae are given for this purpose. A lens may be used as a retro-reflector by providing a metallic coating over part of its surface. A method of manufacture is described in which a quantity of plastics foam beads made, for example, from polyethylene or polystyrene, are foamed to a desired extent by heating and are then sorted into groups of different particle sizes by sieving. A batch having a required bulk density and a corresponding dielectric constant may be prepared by mixing suitable proportions of beads from different groups. Other groups may be prepared from quantities of beads which have been foamed to different desired extents and fine control of the dielectric constant of a batch may be effected by the addition of titanium dioxide. An adhesive binder such as vinyl acetate is mixed with each batch. The core of a lens is prepared by packing a batch of beads having the appropriate dielectric constant into a spherical mould. Moderate heating, for example to 70 C., may be applied to promote hardening. Outer layers may be prepared in two hemispherical halves which are placed together for final hardening. Thus, one half may be made by packing part of a batch of beads between a spherical core or partly-formed lens 20, Fig. 11, and a hemispherical mould 21, and the other half by packing another part of the same batch of beads between hemispherical moulds 22 and 23, whose diameters correspond respectively to those of the mould 21 and the core 20.

Abstract: 1512221 Monitoring battery voltage SOC INTERNATIONALE DE MECANIQUE INDUSTRIELLE 31 July 1975 [31 July 1974] 31972/75 Heading G1U [Also in Division H3] A battery voltage monitor for a motor vehicle has an alarm indicator operative below 13À5 volts and above 16 volts for an increasing battery voltage (e.g. after switch on) but which remains off unless the battern voltage falls below 11À5 volts indicating discharge. At low voltage, none of Zener diodes 116, 115, 124 conducts thus transistor 126 is on, lamp 114 is illuminated and the setting point of the potentiometer 122, 123 is grounded. Thus above 13À5 volts, Zener 115 conducts turning 105 on and extinguishing the lamp 114. Above 16 volts Zener 116 conducts and the conditions are reversed. If the voltage falls below 13À5 volts, Zener 124 remains conducting since transistor 126 is off and thus transistor 105 is held on, keeping the lamp off, until the voltage falls below 11À5 volts. Diodes 121, 120, 125, 124 provide thermal drift compensation.
