Patent GB-1055610-A (GB)
Title: Self-supporting polyamide film
IPC: C09J7/10
Filed: 1965-11-01
Abstract: A self-supporting film is composed of a neutral thermoplastic polyamide derived from a polymerized fatty acid containing more than 80% dimer or a C1- 8 alkyl ester thereof.  The fatty acid may be a saturated or mono- or poly-ethylenically or acetylenically unsaturated acid, e.g. oleic, linoleic, or tall oil fatty acid.  It may be polymerized by the action of heat and/or a basic, Lewis acid or peroxide catalyst and may be hydrogenated before or after polymerization to reduce unsaturation. The ratio of oligomers in the product may be changed by fractional distillation.  At dimer concentrations just above 80% the monomer/ trimer ratio must be within the region 1.8-1.2:1 but as the dimer concentration approaches 100% the monomer/trimer ratio becomes less critical.  The polyamide may be produced by reacting the acid with a polyamine and/or an alkanolamine.  The polyamine may be a C2- 20 alkylene diamine, e.g. 1,3-diaminopropane, 1,4 - diaminobutane, 1,6 - diaminohexane, 1,10 - diaminodecane, 1,12 - diaminododecane, 1,18 - diaminooctadecane, 1,4 - bis - (b  - aminoethyl) benzene, 1,3- or 1,4-bis-(aminomethyl) cyclohexane, ethylene diamine, 1,2-diaminopropane, 3,4 - diethyl - 1,6 - diaminohexane, 3 - ethyl - 1,8 - diaminooctane, 2 - nonyl - 1,10-diaminodecane, or 2 - octyl - 1,4 - diaminoundecane. Alkanolamines may be of formula NH2R111OH where R111 is a C2- 8 alkylene radical, e.g. ethanolamine, propanolamine, butanolamine, 2-amino-3-hexanol, 2-amino-4-pentanol, 5-amino-4-octanol, or 3-amino-3-methyl-2-butanol. Where both polyamine and alkanolamine are used the ratio may be 1:0.05-2. For each mole of fatty acid used 0.05-0.5 mole of a di-carboxylic acid or ester of formula R11OCORCOOR11 may also be present in the reaction mixture where R is a C2- 20 hydrocarbon radical and R11 is H or a C1- 8 alkyl group. Acids of this type specified include adipic, sebacic and suberic acids.  There may be overall a 10% excess of carboxyl groups over amino and hydroxyl groups or vice versa. The polymerization temperature may be 150-300 DEG  C. Film of 3-5 mils thickness may be used to bond surfaces by heat-softening it in contact with the surfaces or subsequently cooling it until it hardens.  A pressure of up to 15 p.s.i. may be used.  The process may be used to seal the seams of metal containers, for sealing gaskets and for bonding paper and plastics.

[Also in Divisions D1 and F2] A gear pump draws lubricant from space 36 through filter 46 and pipe 47. Drive gear 26 and meshing gear 25 circulate lubricant throughpassage 42, passage 52 in valve member 48 and passage 43. Gears 26, 27 circulate lubricant through passages 45, 53, 44. On starting a sewing machine to be lubricated, valve member 48 rotates through a small angle thus disconnecting passages 52, 53 from the circuits. Lubricant then flows through passage 64 to the machine. Lubricant is returned from the machine through passage 67. On stopping the machine, lubricant flow is stopped. An adjustable non-return check valve 92 determines the maximum pressure delivered to the machine.

A composite material comprises glass reinforced with carbon fibres produced by controlled thermal degradation and oxidation of organic fibres. The fibres preferably are produced from polyacrylonitrile, and preferably comprise 10- 70% by volume of the material. They may be short (e.g. 0À5-10 mm.) or in long lengths, and may be randomly oriented or aligned. The glass may be a borosilicate or soda-lime-silica glass, or a devitrified glass (e.g. an aluminosilicate). Examples of suitable glasses are given. The fibres may be incorporated in the molten glass, e.g. by casting, moulding, rolling or extruding, or mixed with the powdered glass and consolidated by hot pressing, preferably under vacuum. The latter method is used particularly with powdered devitrified glass. Alternatively the glass may be devitrified after forming the composite. Carbon fibres may be coated with powdered glass in suspension (e.g. in isopropyl alcohol or methyl ethyl ketone) with a binder present (e.g. polyvinylacetate or acrylic epoxy resin), and vacuum hot-pressed at, e.g. 800‹ C. Carbon fibres may also be coated with glass by electrophoresis from a suspension in methanol or with a ceramic oxide or metal.

An electronic flash apparatus for attachment to, or incorporation in a photographic camera has means for producing a preliminary flash of predetermined intensity to illuminate a subject whilst the camera shutter is closed, and means for producing a second flash whilst the shutter is open, the intensity of the second flash being varied by photo-electric means in inverse relation to the illumination of the subject produced by the combination of the preliminary flash and ambient illumination. The two flashes may be produced in a single flash-tube 52 connected in a firing circuit 6 powered by a D.C. supply circuit 11 and containing capacitors 39 and 40 for providing the energy for the first and second flashes respectively and ignition coils 49, 50 with associated capacitors 41, 42; the second firing is initiated by a mono-stable Schmidt trigger circuit 11 controlled by a time-circuit 9 containing a photoresistor 14 and a capacitor 17. In operation, a switch 30 is closed to charge up the capacitors, which charging is indicated by audible or visible means; the shutter release is then depressed first closing a switch 13 which renders the timecircuit ready for operation and then simultaneously opening a switch 18 and closing switches 45, initiating a controlled discharge of capacitors 40, and 53, causing ignition of the preliminary flash. Opening of switch 18 causes capacitor 17 to be charged through photo-resistor 14, until after a time determined by the illumination of the latter, the voltage of the capacitor is such to change the state of a relay 28 in the trigger circuit; this closes contacts 28a, 28b of the relay, thus respectively shorting out a diode 43 which prevents capacitor 40 being totally discharged and effecting an ignition of the flash-tube. The intensity of the flash, which is governed by the voltage of capacitor 40 which is determined by the time it discharges before firing, which is controlled by the photo-resistor in the time-circuit. In modifications the voltage of capacitor 40 may be varied by charging instead of discharging, and/or relay 28 may actuate the closing of an electromagnetic shutter.
