Abstract: 1,184,675. Bulldozer-bucket units. HAYNESWHETSTONE CO. Inc. 6 Oct., 1967, No. 45840/67. Heading E1F. In a dozer-bucket unit a plate 21 is so mounted between the side walls 14 of the rest of the unit that it can be raised from a dozer blade-functioning position in which it extends between the front edges of the side wall with its lower portion extending below to abut against the front edge of a bottom plate 16 interconnecting the side walls to clear said front edge for subsequent rearward pivotal movement through the unit to form when positioned between the rear edges of the side walls a back wall to a shovel as then defined by the unit. The blade may be supported from each side wall by a crank comprising a swing- able arm 24 on a shaft 26 that is caused to rotate by a rack and pinion mechanism or a ram to control raising and lowering of the plate when at the front of the unit. In another embodiment cam followers on the plate cooperate with cam slots in the side walls for controlling said raising and lowering of the plate.

Abstract: 1,071,917. Shaping thermoplastic fibrous materials. FORSCHUNGSINSTITUT FœR TEXTILTECHNOLOGIE. Nov. 12, 1964, No. 46148/64. Heading B5A. [Also in Divisions D1 and H1] A web of thermoplastic fibrous materials which comprises longitudinal tubular cavities is shaped and stiffened by passing the web through a heating chamber 3 and a cooling chamber 4 with stationary rods 2 being disposed within the tubular cavities. The web may be a double cloth or made by sewing, sticking or welding together two independent webs, and in a preferred form, the web or webs have polyester fibres as a main constituent with up to 30% by weight of P.V.C. fibres, used as weft only. The shaped and stiffened material may be used as plates or pockets in lead-acid batteries, in filters or in protective clothing. The rods 2 are held at a necked portion thereof by clamping rollers 5, 6 which are rotated at a speed the same as, or slightly greater than, the draw-off speed of web 1. Rollers 7-10 counter any tendency of rollers 5, 6 to bend or warp. Heating in chamber 3 may be effected by hot air blowers, by conduction, by radiant heat, e.g. using infrared heaters, by steam or by sprinkling hot water on the web. Rollers 12-15 co-operate in pairs, see also Fig. 2 (not reproduced), to shape the web and provide side flanges (1c), Fig. 4 (not shown), and intermediate connecting portions (1b). These side flanges and connecting portions are engaged by needles 20b, Fig. 1, which are pressed into the material by rotating brushes 25 to draw-off the web. The web is removed from the needles by a cross-bar 26 and the side flanges are trimmed or removed by trimming knives 27. A transverse cutter 30 is also provided.

The travel of the piston is limited by a spacer (48), and the links are retained in their overcentre position by a spring 92. The pivot axis 19 of the hinge 15 is inclined to feathering axis 18 so that the several blades of the rotor do not interfere during folding, and to the rotor plane so that each blade clears the ground adequately.

Abstract: 975,549. Helicopter rotors. LOCKHEED AIRCRAFT CORPORATION. Dec. 17, 1962, No. 47469/62. Headings B7G and B7W. Each blade, such as 16, of a rigid helicopter rotor 13 rotatably mounted on a hub about a feather axis FA behind the aerodynamic axis AA, considered in the direction of rotation- (anti-clockwise as seen in Fig. 3) and has a cross arm 26 fixed to it at the root, the arm declining forwardly when the blade is in the zero-lift position, and having at its forward end a weighted disc 31 with a positive incidence. One effect of the discs 31 is to reduce the blade pitch when the rotor speed is reduced, so that when idling on the ground vibration is reduced. The The flywheel effect of the discs also stabilizes the helicopter, since, if the helicopter pitches or rolls, the discs will cyclically alter the pitch of the blades to counteract this. The rotor blades are connected by tension springs 23 to a swashplate 22 to allow these variations in blade pitch.

Abstract: 1,217,949. Process for producing cured plastics articles. DOW CHEMICAL CO. 11 Oct., 1968 [30 Oct., 1967], No. 48361/68. Heading C3P. [Also in Division F2] A cured plastics article is produced in two separate stages: in the first stage a composition comprising a thermosetting resin and one or more volatile monomers capable of reacting chemically with the resin, initially at a temperature below the boiling point(s) of the monomer(s) and below the temperature at which a gel is formed, is subjected to a rapid increase in temperature so as to form a gel within 5 minutes from the commencement of the temperature increase; and in the second stage the temperature of the resulting gel is raised to the curing temperature thereof to form a cured plastics article. Preferred monomer(s)/resin compositions are an unsaturated polyester resin containing an ethylenically unsaturated monomer; a vinyl ester resin, polymerizable with the monomer(s) used, containing an ethylenically unsaturated monomer; or an epoxy resin containing a volatile monoepoxy diluent. The resin/monomer mixtures used in the examples were a vinyl ester resin prepared from maleic anhydride, #-hydroxyethyl acrylate and a polyepoxide resin prepared from bisphenol A and a hydrogenated bisphenol polyester, both dissolved in styrene. This is cured on a mandrel either alone to form a liner or with wound fibreglass reinforcement.

Filed: 1975-11-25
Abstract: 1492469 Valves ACTROL INDUSTRIES PTY Ltd 25 Nov 1975 48396/75 Heading F2V A reducing valve has a seat and valve member 29, 28 at one end of a passage 16 and a balancing member 35 at the other. A pressure responsive means 18 is movable against a spring 20 by pressure downstream of the valve to close the valve, the valve being held closed by a spring 31 when the downstream pressure is less than sufficient to overcome spring 20. The reducing valve is particularly suitable for mains water pressure reduction to hot water systems. As shown a piston 18, under outlet pressure acts against a spring 20 on the valve 28 through a cage 25. The effect of inlet pressure on the piston via the valve and cage is balanced by equal pressure on the plug 35. If the pressure differential is reversed, spring 31 keeps the valve closed to act as a non-return valve. A diaphragm 18a, Fig. 2 (not shown), may replace the piston as pressure responsive member.
