Title: Improvements in the Bonding of Filamentary Materials of Synthetic Linear Polyesters to Rubber
IPC: C08J5/06
Filed: 1966-11-08
Abstract: 1,154,007. Treating polyester fibres. CELANESE CORP. 8 Nov., 1966 [12 Nov., 1965], No. 49985/66. Heading D1P. Improved adhesion of synthetic linear polyester filamentary material to natural or synthetic rubber is obtained by applying to the fibrous material an ester having the formula X C 6  H 4  COOR in which R is an alkyl group containing 1-6 carbon atoms and X is an alkyl group containing 1-6 carbon atoms or a hydrogen or halogen atom, before or at the same time as there is applied thereto an adhesive and then embedding the material in the natural or synthetic rubber and vulcanising. The ester which may be applied to the polyester fibrous material without dilution, as a solution in xylene, acetone, methanol, propanol or tetrachloroethane or as an aqueous suspension by dipping, brushing or spraying, may be methyl, ethyl or butyl benzoate, methyl p-chloro benzoate, butyl m-bromobenzoate, ethyl p-methylbenzoate or butyl o-ethylbenzoate. The ester may be applied to the fibrous material at 10‹-150‹C and the material then partly or completely dried, e.g. at room temperature for several hours or at 100‹C for a few minutes. The treated material may be heat set at 150‹ - 245‹C for ¢ - 5 minutes. An aqueous adhesive composition comprising a resorcinol-formaldehyde resin precondensate together with isocyanates, blocked isocyanates or epoxy compounds and aqueous rubber latex dispersions e.g. a butadiene-styrene-vinyl pyridiene copolymer and a styrene butadiene copolymer may be used. After treatment with the ester and adhesive either separately or together the fibrous material may be dried and heated for 1-5 minutes at 60‹ - 250‹C if desired under tension. Suitable synthetic rubbers are those obtained by polymerising a conjugated C 4  - C 6  diolefine either alone or with styrene, methyl styrene or acrylonitrile or by polymerising chloroprene alone or with dienes or vinyl compounds, and elastomeric ethylene-propylene copolymers and terpolymers. The rubber may also contain sulphur, sulphur chloride, thiuram poly-sulphides, carbon black, pigments, anti-oxidants and anti-scorch agents. The process may be used in the production of vehicle tyres and transmission and conveyor belts.

Patent GB-1096296-A (GB)
Title: Method of controlling the operation of moving grate sintering installations
IPC: G01G19/32
Filed: 1964-12-10
Abstract: <PICT:1096296/C1/1> In a moving grate sintering operation, the input of ore, coke, and returns to the grate is controlled automatically by the use of a first controller (R1) which compares the amount of returns in the returns bin with a set desired value (S1) and produces a signal representing the returns input/ore input ratio necessary to maintain S1, and a second controller (R2) which receives the signal from R1, compares it with a set desired value (S2) of returns production/ore input, and produces a signal representing the coke/ore input ratio necessary to maintain S2; the signals from R1 and R2 are then fed to a calculator (9) which regulates the ore, coke, and returns inputs to tend towards the ratios represented by the signals. Thus, if excess returns are produced, the system adjusts to feed more returns, less ore, and more coke on to the grate, and thus decrease the returns production.  Ore from bins 10 and 11, coke from 12, and returns from 5, are fed by means of belt weighing devices B1-B4 on to conveyers 2 and 13, thence to mixing drum 14 and bin 15.  The weight of mixture in bin 15 is compared with a desired feed value prescribed by computer 8 and any feed adjustment necessary is transmitted in calculator 9 to B1-B4.  The mixture is then sintered on grate 1 (supplied with covering material from bin 16), screened, cooled, and screened again.  Returns are recycled to bin 5 e.g. by bucket conveyer.  The layer weight (h), and speed (v) of grate 1 (which is adjusted so that final combustion occurs at the end of the grate) are transmitted to computer 8, and used to calculate returns production R (from which S2 is obtained) from the equation F = Av.h-R (where F is the amount of final product, and A is a constant).  Preferably S2 (wt. ratio of returns produced to ore input) is 0.3-1 and the wt. of coke input/ore input is 6-8%.  If these limits are reached, a signal may be emitted, or the layer height (h) adjusted.  The amount of returns in bin 5 may be measured by weight or depth.

An aircraft flight recorder 5, which is buoyant (e.g. by having a floatable tank 6 attached thereto) is ejected from an aircraft when the aircraft sinks after ditching by apparatus comprising a releasable cover 15 covering an opening to the location of the flight recorder, a normally shut valve (e.g. a flap 17) sealing the location from the exterior of the cover, an ejection device (e.g. a spring 10) for ejecting the flight recorder outwardly through the opening, and a mechanism (e.g. a barometric switch 19 activated by water entering the inlet 20) which on actuation opens the valve 17 to flood the location thereby relieving the pressure differential across the cover, releases the cover and also causes the ejection device to operate. The barometric switch 19 when triggered withdraws a pin 21 allowing the spring 50 to collapse a toggle linkage 22, 23 which in turn withdraws a hook 24 releasing the spring 10, and via a linkage 28 to 32 withdraws a hook 36 releasing the cover 15 and the flap 17. There may be three hooks 36 and three flaps 17 moved together by three links 30 moved together by an interconnection 70. The flight recorder 5 may be connected to aircraft instruments by a cable 7 having two push in connectors 8, 9 of which at least one disconnects when the recorder is ejected.
