The nozzle 1 feeds the permeable surface which is in the form of a screen 2 to which suction is applied and it is attached by a pantograph structure 4 to a programming head 5 which follows. A chosen pattern inscribed on a rotating disc 6; the nozzle is removably attached to a member providing a constant head of the dispersion, Fig. 2 (not shown). The permeable surface may be rotated while the nozzle is reciprocated, Fig. 4 (not shown), or is stationary, Fig. 5 (not shown). Two stationary nozzles may feed a single rotating surface, Fig. 6 (not shown). The nozzle may be reciprocated over a stationary surface, Fig. 7 (not shown), which is thereafter rotated to different positions, e.g. by 60‹, and further layers of fibres deposited on top of the first layer. Masks or studs may be applied to the permeable surface to modify the pattern. The laid fibres may be coated with a binder, e.g. methyl methacrylate until required. A flowable matrix material may be allowed to penetrate the laid fibres and then solidified to provide a composite material. Articles may be formed with the fibres conforming to the predicted pattern of stress to which the articles may be subject in service. The carrier liquid may have a viscosity of at least 20cp. at 20‹C. Liquids referred to include water, glycerol, aqueous solutions of alginates, solutions of resins such as epoxy resins in solvents, sugar syrup, and viscous oils.

Abstract: 1408775 Rocket propulsion units - starting MESSERSCHMITT-BOLKOW-BLOHM GmbH 300ct 1972 [10 Nov 1971] 49885/72 Heading F1J The invention relates to a method of starting of a liquid fuel rocket of the kind comprising one (or more) pre-combustion chambers 4, a main combustion chamber 2 and propulsion nozzle 3, there being a turbine 6 disposed in the gas flow-path between the pre- and main combustion chambers, the turbine being connected to drive a fuel pump 11 and an oxidizer pump 10. An ignition chamber 25 and auxiliary fuel and oxidizer containers 29, 28 also a pressurizing gas tank 38 are also provided. Oxidizer is caused to flow through cooling passages extending through the wall of the main combustion chamber and propulsion nozzle. At starting, the valve 39 is opened whereby the containers 29 and 28 are pressurized by gas from the tank 38. Fuel and oxidizer pass to the ignition chamber 25 through the open valves 33, 31 and the resulting combustion gases which contain excess oxidizer pass through the open valve 27 into the oxidizer chamber 5a of the pre-combustion chamber 4, the gases passing through the turbine, main combustion chamber and propulsion nozzle whereby these parts are pre-heated. The turbine acts to drive the fuel and oxidizer pumps whereby fuel passes through open valve 24 into the pre-combustion chamber and oxidizer passes through open valve 16 to the cooling passages 17 and thence through the chamber 5a into the pre-combustion chamber. The valve 23 is then opened whereby fuel passes into the main combustion chamber for reaction with the excess oxidizer discharging from the precombustion chamber. The ignition chamber is operated continuously by closing valves 39, 33, 31 and opening valves 37, 35 so that fuel and oxidizer delivered by the pumps 11, 10 pass to the ignition chamber. The fuel may be asymmetrical dimethyl hydrazine (ADMH) and the oxidizer nitrogen tetroxide (N 2 O 4 ).

Each valve spindle 27 carries a cam plate 37 with cams 39, 41, 42 and 43, the cam 39 being on the opposite side of the plate to the other cams. As the kiln rotates the cams are actuated in turn to index the plate 37 by trip devices 29, 31, 32 and 33, the latter actuating the cam 39 and being retractable by an hydraulic servomotor 34 and valve V. Trip devices 29, 31 and 32 operate each valve 18 to a " fuel-on ", " fuel-off " and " air-on " position and device 33 operates the valve to an " air-off " position. On lighting up the kiln, trip device 32 leaves each valve in an " air-on " position and device 33 is retracted preserving this position. When the kiln is fully heated a relay R is deenergized operating valve V and servomotor 34 to restore trip device 33 to its operative position. The kiln is then charged and with all the trip devices fully operative fuel is supplied into the charge material as each nozzle 12 passes below it and air is discharged through each nozzle in the upper position until it reaches the trip device 33.
