Abstract: 1,110,659. Moulding fragmentable structures. HAWLEY PRODUCTS CO. 9 May, 1966, No. 20436/66. Heading B5A. [Also in Divisions D1 and F3] Nose and tail fairings (30, 31) (Fig. 6, not shown), of elliptical shape for aircraft rocket launchers and which fragmentize into small pieces to avoid damage to the aircraft upon launching of rocket, are moulded from a fibrous preform, e.g. of 70% sulphate cellulose fibres, 23% mechanical (shredded wood) and 7% ground wood, with 1À8% of melamine formaldehyde (on the dry fibre weight) to improve the wet strength, which preform is accreted by suction from a slurry on to a porous screen and is then dried under pressure between a preferably movable smooth-faced female die 40 and a preferably fixed male die 50 which is provided with interlacing axially and circumferentially extending grooves 52, 53 into which the fibrous structure of the preform is displaced to form axially and circumferentially extending raised ribs (35, 34) on the interior of the moulding whereby the fibrous structure of the ribs and in the moulding therebeneath is less dense than that of contiguous areas thereof and, when impregnated with a brittle resin, forms regions of a higher resin to fibre ratio which are more brittle and at which fracture occurs upon launching of the rocket. The ribs (34, 35) of 0-09 to 0À12 inch thickness and “ inch width enclose less brittle areas of approximately 2 sq. inches of 0À06 inch thickness. The front portion (A) of the nose fairing (30) may be dip impregnated with brittle phenol or melamine formaldehyde resins from an alcohol or an alcohol-water solvent mixture and the rear portion (B) may be impregnated with a high impact polystyrene in toluene or mixed solvents, a styrene/acrylonitrile/butadiene, or a polymethylmethacrylate resin whereby the fragmentation of the front portion (A) precedes that of the rear portion (B). The phenol or melamine resin dip impregnated fairing is rapidly heated to drive off the solvent and subsequently cured for a longer period in an oven. The polystyrene impregnant is usually applied in two dipping operations followed by air drying. The dies 40 and 50 are preferably heated by hot gases supplied by one or more respective burner nozzles 45, 57 to the rear of the moulding surfaces thereof and the moulding surface 51 of the male die 50 is provided with a plurality of small drain grooves 61 which connect, via an annular recess 62 in the base of the die, to a vacuum space 64.

Patent GB-728079-A (GB)
Title: Improvements in resin compositions
IPC: D06M15/39
Filed: 1952-08-18
Abstract: An emulsifiable resin consists essentially of the interaction product of a water-insoluble thermosetting resin and a heteropolymer of styrene and a partial ester of an unsaturated polymerizable polycarboxylic acid, the interaction product containing free carboxyl groups and the interaction being effected in a non-aqueous environment in the presence of an alcohol such as butanol or a compound containing an alkyl radical, which alkyl radical may be supplied by using an alkylated thermosetting resin.  The thermosetting resin may be a melamine-, triazine-, or urea-formaldehyde resin, which may be butylated, a thermosetting alkyd resin or a mixture of two or more of said resins, and the heteropolymer may be a copolymer of styrene and a partial secondary butyl ester of maleic, itaconic or fumaric acid.  The emulsifiable resins may have pigments dispersed therein, with or without a pigment-dispersing agent such as a sulphonated phenolformaldehyde resin, and emulsions formed from the resins may be stabilized by neutralizing the free carboxyl groups present by reacting with a base material such as ammonium hydroxide, a primary or secondary amine or caustic soda, while the interaction product is in aqueous emulsion. The emulsion may also contain a copolymer of butadiene and acrylonitrile, or of acrylonitrile and vinyl chloride, polyvinylidene chloride or a nylon, or an emulsifying agent such as an alkyl aryl polyether alcohol, triethanolamine oleate or stearyl dimethyl benzyl ammonium chloride, or a water-repellant such as a silicone, tetrafluorethane or wax.  The emulsions may be used for the printing, dyeing and coating of textiles and paper.

Title: Improvements in or relating to electric motor control systems
IPC: B66C9/16
Filed: 1943-12-13
Abstract: 578,607. Automatic control of several motors. IGRANIC ELECTRIC CO., Ltd. Dec. 13, 1943, No. 20861. Convention date, Dec. 12, 1942. [Class 38 (iv)] [Also in Group XXXVII] Alignment.-In a control system for a travelling structure, e.g. a bridge, a pair of electric motors, mounted on the structure and driving wheels at opposite ends thereof, have common control means for starting and stopping and means responsive to over travel of either end of the structure to correct skew of the structure by control of the relative speed of the motors. A variable voltage generator 3, driven by a motor 2 and having a field 4, supplies power to the armatures of two groups of D.C. shunt motors 6 and 8 driving each end of a bridge respectively. A D.C. source L1, L2 supplies the fields of the generator and driving motors and also the operating windings of the various relays. Starting, stopping, speed control and reversal of the motors is by master controller 33. Push button 37 is for emergency stopping. Wheels 10 and 12, which are idler wheels rotated in proportion to the distance moved by each end of the bridge, are coupled through a differential gear 11 to a rheostat 15 which moves one way or the other according to the relative positions of the bridge ends, thereby altering the field current of motors 8 during controller operation to correct any tendency of the bridge to "skew". Rheostat 39 is provided to adjust the speed of motors 6 so that rheostat 15 maintains, normally, an intermediate position. The differential also drives a limit switch 16 which operates if, in spite of the action of rheostat 15, the bridge gets out of alignment, so that when the master controller is put to " neutral " one set of motors runs to effect correction after the other set has stopped. A further limit switch 20 operated by the differential is provided to stop the equipment if the skew becomes excessive. Three motor speeds are obtained in each direction by inserting resistances 36 and 36a in the generator field circuit, reversal being effected by reversal of the generator field. The master controller may be thrown quickly from any one position to another since relay 35 controls the connection of the driving motor armatures and is energised from generator 3.
