Patent GB-1065721-A (GB)
Title: Unsaturated polyesters and thermosetting products produced therefrom
IPC: C08G63/676
Filed: 1963-09-30
Abstract: An unsaturated polyester is made by (a) reacting a phenol of formula (II) <FORM:1065721/C3/1> wherein R1 and R2 are hydrogen atoms or aliphatic radicals, R3 is an alkyl, alicyclic, aryl, aralkyl, methyl-keto or phenyl-keto group, and R4 is an aralkyl, haloaralkyl or alkylaralkyl group with an aldehyde or a ketone to form a phenolic condensation product, (b) reacting the phenolic condensation product with a mono-oxirane compound, an alkylene halohydrin or an alkylene carbonate to form a poly(hydroxyether) derivative, and (c) polyesterifying the hydroxyether by reacting it with an alpha,beta-ethylenically unsaturated polycarboxylic acid or an anhydride or acid halide thereof.  Step (a) is effected in the presence of an acid or basic catalyst with a mol ratio of aldehyde or ketone to phenol of 0.5 to 0.85.  Step (b) is preferably effected using 1 to 3 moles of mono-oxirane compound or other etherifying agent per mole of phenolic hydroxyl. Step (c) may be effected using as additional reactants polycarboxylic acids (or their anhydrides or acid halides) which are not alpha, beta-unsaturated or dihydric alcohols (e.g. alkylene or oxyalkylene glycols or cycloaliphatic dihydric alcohols).  In examples, phenol was aralkylated by reacting 1 mol thereof with 1.5 or 2 mols of styrene, vinyl toluene, or alpha-methyl styrene, the resulting phenol reacted with formaldehyde and the product then hydroxyalkylated by reacting it with ethylene oxide, propylene oxide, butylene oxide, styrene oxide, ethylene chlorohydrin, ethylene carbonate or propylene carbonate. The resulting poly(hydroxyether) was then polyesterified with maleic, fumaric, itaconic or chloromaleic acid, possibly in admixture with propylene glycol, diethylene glycol, dipropylene glycol or tripropylene glycol.  The unsaturated polyesters may be copolymerized with the usual unsaturated monomers, possibly in admixture with fillers or fibrous reinforcing media.  In examples the specific unsaturated polyesters referred to above were copolymerized with styrene, vinyl toluene or vinyl acetate.  In some examples copolymerization was effected in the presence of tertiary butyl perbenzoate, calcium carbonate, asbestos, 1/4 -inch glass fibres and zinc stearate to form moulded bodies.  In others, copolymerization was effected in the presence of benzoyl peroxide and glass fibre cloth to form laminates.

Title: Aircraft landing approach ground proximity warning system
IPC: G05D1/06
Filed: 1975-09-26
Abstract: 1478940 Aircraft warning indicators SUNDSTRAND DATA CONTROL Inc 26 Sept 1975 [3 Oct 1974] 39457/75 Heading B7W An aircraft landing approach ground proximity warning system uses a waypoint signal from an area navigation system in combination with a radio altimeter signal to compute a minimum altitude for each point along the approach path, and if the aircraft's actual altitude falls below said minimum an alarm signal is generated. A distance-to-waypoint signal is received over line 24, representing distance of the aircraft in miles from the end of the runway, and fed, together with a further signal from a source 28 representing minus half a mile from the end of the runway, to a summing junction 26. The output from junction 26, which therefore represents the distance of the aircraft from the end of the runway less half a mile, is fed to a scaling amplifier 30 which has its gain adjusted to a ratio that will give a minimum glide slope from an altitude of 750 feet 3À5 miles from the intersection with the runway. The output from amplifier 30 is fed to a summing junction 32 which receives also a signal on line 34 from a radio altimeter so that junction 32 will generate a positive signal if the aircraft is above said glide slope and a negative signal if below it, said signals being fed through a detector 36 the output of which is fed to an AND gate 38 together with a signal from a signal generator 40 responsive to the radio altimeter. Should the aircraft descend below the computer glide slope path the gate 38 will activate a warning device over line 44.
