Abstract: 1295753 Gas turbine plant; hydraulic reciprocating pumps SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION 23 April 1970 [24 April 1969] 19539/70 Headings F1G, F1A A gas turbine engine includes a combustion chamber 3 having main and auxiliary fuel injection systems, the auxiliary system being supplied at ignition of the chamber by a piston and cylinder type auxiliary fuel pump, means being provided to automatically adjust the fuel injected into the chamber by the main system at ignition as a function of the relative positions of the piston and cylinder of the auxiliary pump. The main fuel injection system includes a gear type pump 8, pilot operated regulator 9, drain 10 and injection nozzles 5. The auxiliary system includes a piston type pump 13, and injection nozzles 6 disposed with in at least one ignition chamber 11 provided with a plug 11a. Prior to starting, the chamber B to the right of the auxiliary pump piston 14 is full of fuel and the pilot's lever M is in the position A shown. To start the engine lever M is moved to position R and the main pump 8 begins to fill injectors 5 through pipe 7. The pressure rise in the latter is communicated through pipe 26 to the chamber A on the left side of piston 14, thus causing the piston and a rod 27 secured thereto to move to the right against spring 18, opening port 26 and forcing ignition fuel through pipe 12 to injectors 6. As this movement takes place piston 14 uncovers a nozzle 34 in cylinder wall 15 so that part of the output from pump 8 is bypassed back to the pump inlet via pipe 32, nozzle 34, annular chamber C and pipe 33. The portion 35 of piston 14 is contoured such that the fuel bypassed back is a function of the piston position and the fuel/air ratio in combustion chamber 3 remains at an optimum value during the starting phase. At the termination of the latter, piston 14 arrives at its extreme rightwards position Fig.3 (not shown), so that seal 28a on rod 27 closes port 26 to prevent any further ignition fuel flowing to injectors 6. Simultaneously nozzle 34 is completely blocked by piston portion 35 so that bypass back from the main pump 8 is prevented, regulation of the fuel flow being taken over entirely by regulator 9. During normal running piston 14 remains in its rightwards position but when lever M is returned to its "stop" position A the pressure in chamber A falls so that spring 18 forces the piston the return to the left. This causes a pressure reduction in chamber B so that fuel is sucked into the latter from upstream of pump 8 via pipe 33, chamber C and passages 20, 19, 24 and non-return valve 17 disposed in piston 14. The system is thus ready for the next ignition phase. The auxiliary system includes a pipe 12a bypassing injectors 6 and enabling the auxiliary system to be scoured with fuel between ignition phases to prevent pipe blockages.

Title: Method of pressure welding of overlapping metallic workpieces and  device for its realization
IPC: B23K20/04
Filed: 1970-03-12
Abstract: 1308972 Welding by pressure INSTITUT ELEKTROSVARKI IMENI E O PATONA AKADEMII NAUK UKR SSR 12 March 1970 11888/70 Heading B3R In a method of pressure welding overlapping metallic workpieces a tool is pressed progressively into one of the workpieces in a direction normal to the plane of contact of the workpieces to cause plastic deformation and metal flow and the rate at which the tool is pressed into the workpiece as welding occurs is between 0À1 and 0À6 of the rate of metal flow. Overlapping strips 4 are mounted on a displaceable support 3 below a cam-profiled roller 1. Rotation of the roller 1 grips the workpieces and progressively reduces the thickness thereof while simultanously effecting a fed movement of the strips together with the support 3. The cam profile and inclination (if any) of the upper surface of the support 3 are designed to give a predeter. mined speed of squeezing of the workpiece which at the point where welding occurs is in the desired relationship to the rate of metal flow. The latter is defined as being the rate of elongation of the workpiece under the tool. In a second embodiment (Fig. 3, not shown), suitable particularly for ductile metals such as aluminium and copper and low-carbon steels the upper surface of the support is horizontal. In a third embodiment an internal boss is welded to a pipe. For welding metals of low ductility the workpieces are preferably heated to facilitate plastic deformation. Reference is made to the welding of brass and constantan, phosphor bronze and constantan, and brass and bronze and to the cladding of precision formed and heat resistant metal and alloys.

Abstract: 1315963 Electro-chemical machining TUBES Ltd 19 Nov 1970 [26 Aug 1969] 42451/69 Heading C7B In a technique for electro-chemically machining a recess or aperture in a workpiece, the electrochemical machining tool is rotated eccentrically. The nature of the recess or aperture is consequently independent of the dimensions of the tool. The technique is particularly described with respect to the apparatus disclosed in Specification 1315962 wherein the tool is axially displaced. The tool holder 17 comprises a cylinder in which is mounted a plunger 19 to which the tool 15 is attached. The plunger 19 is biased in one direction relative to the cylinder by means of a spring 20 and has a connection 21 through which hydraulic fluid can be passed to move the plunger 19 and so axially displace the tool 15. Consequently, when the tool holder is rotated the tool moves eccentrically. In order to make this movement of the tool automatic, a probe 24 may be provided contacting a cam (25) connected to the workpieces. As the workpieces move, cam (25) rotates moving the probe so operating electrical switches (not shown) that actuate a hydraulic fluid inlet valve.

Abstract: 1316083 Automatic flow control DELTA CONTROLS Ltd 30 July 1970 [12 June 1969] 29941/69 Headings F1C C2J1A C2J1D C2J2C1 and C2J2J3 The setting of a flow valve is controlled to maintain a constant pressure drop across the valve. The valve setting automatically energizes a sufficient number of pumps to deliver the demanded fluidflow. As shown, a valve 12 controls the supply of fluid, e.g. aircraft fuel, to a main 14, and switches 36, operated when the pressure drop across the valve is above or below predetermined limits, control a reversible servomotor 28 so that the valve is adjusted to maintain the pressure drop, and hence the fluid-flow, between limits. Pump 1 normally operates to supply fluid to valve 12 but, as the valve is opened, valve stem 18 operates switches 44 in succession to introduce further pumps 2-N as required to meet demand. A switch 38 stops all pumps if the pressure on the upstream side of valve 12 becomes excessive. If valve 12 closes completely, a torque limit switch operates to stop motor 28. If valve 12 opens too far, a switch 45 operates to cut off all supplies and sound an alarm. A pressure relief valve on the upstream side of valve 12 may replace switch 38 so that pump 1 may run continuously. A PID controller responsive to the pressure drop may control motor 28 instead of switches 36.
