Abstract: 335,491. Budd Wheel Co., (Assignees of Tarbox, J. P., and Reed, G. B.). Jan. 26, 1929, [Conventon date]. Welding wheels. - Hollow members, such as spiders of sheet metal artillery wheels for automobiles &c., are flash welded by applying pressure to the outside of one of the elements and a vielding pressure to the interior thereof while bringing it into welding position with relation to the second element. The halves of a spider 34 are flash welded between a, fixed die 30 and an hydraulically operated die 31 to which the terminals of an annular series of transformers 39 are connected. The lower half is first placed on the die 30 and a series of radial yielding wedgebars are placed over the spoke elements 32 and are simultaneously or subsequently expanded, whereupon the upper half is placed with its elements 33 over the bars and the die 31 is operated to perform the weld, the parts being clamped between the ties and the wedges which yield to the pressure of the die 31 to perform the flash weld. In one form each internal bar may consist of two parts 41. 42, Fig. 14, expanded by a spring 55 compressed by a nut 56 after insertion. The parts 41, 42, Fig. 14, expanded by a spring 55 compressed by a nut 56 after insertion. The parts 41, 42 may, however, be carried respectively by extensions 47<1> from cylinders 46 movable by air pressure on fixed pistons 44 and by links 50 secured to the piston-rods of cylinders 49. The cylinders 46 are moved forwards simultaneously to insert the bars in the spokes by pneumatic pressure from a high pressure line 65 through connected valves. The pistons 49<1> are retracted to expand the wedges by air pressure throush connected valves from a low pressure line 64 and are pushed forward to contract the wedges by high pressure from the line 65. The high and low pressure lines may be connected through a valve 67 when necessary. The wedge bars may be provided with engaging side plates 51, 52, Fig. 10, the upper bar 42 having a wear resisting plate 53 and leaves of insulation 58 being placed between the bar 41 and the element 32. In another form, Fig. 13, the bar 41 may be embraced by a layer of fibre 51 coated on its lower surface with metal by spraying, and the bar 42 may be covered by a U-shaped plate 52. In order to avoid displacement of the insulation 58 during insertion of the wedge bars, the cylinders 46 may be raised by mounting thereon dogs 60 with edges 61, 62 of different radii to engage guides 63, pins 66 being provided to engage detents 64, 65 at the ends of its movement to bring either of the edges into engagement with the guides.

Title: Fuel systems for gas turbine engines
IPC: F02C7/22
Filed: 1972-01-12
Abstract: 1361481 Fluid regulation DEFENCE SECRETARY OF STATE FOR 12 Jan 1972 [19 Jan 1971] 2723/71 Heading G3H [Also in Division F1] The invention relates to a fuel system for a gas turbine engine which comprises a drains tank for receiving excess fuel from the main supply line, there being means for permitting transfer of fuel from the drains tank back to the supply line, there being further means for preventing the passage of air through the transfer duct. The system shown comprises a main fuel pump 11 in supply line 10, a drains tank 1 to which excess fuel flows through line 2 and from which fuel flows through transfer duct 14 back to the suction side of the pump. A return passage 12 is disposed across the pump 11 and comprises an ejector pump 13 to which the transfer duct 14 is connected. Two fluidic devices are disposed within the drains tank, a detector device 25 and a supply device 32. The device 25 comprises an open-sided chamber 26 having an inlet port 29 and an outlet port 30, high-pressure fluid being supplied to the inlet port 29 through line 31 from the discharge side of the main fuel pump 11. When the level in the drains tank is low, fluid passes from the inlet port 29 to the outlet port 30 and thence through line 33 to the inlet port 39 of the second fluidic device 32. The device 32 also comprises an open-sided chamber 34 having an inlet port 36, an outlet port 37, also the inlet port 39. HP fluid is supplied through line 38 to the inlet port 36 and in one phase of operation fluid is also passed through line 24 to the port 37. When the level in the tank is low and fluid is passing through line 33 to the inlet port 39, the three jets of fluid impinge on each other and fluid enters the tank. When the level in the tank is high the passage of fluid across the device 25 is interrupted so no fluid passes to the port 39 of the supply device 32. Fluid now passes from the inlet port 36 to the outlet port 37, the pressure of fluid in line 38 being greater than that in line 24. Thus no fluid enters the tank from the device 32. Fluid is at all times drawn from the tank through line 14 by the ejector pump 13.

Abstract: 1304530 Diffraction grating systems AGFA - GEVAERT AG 21 Jan 1970 [21 Jan 1969] 2910/70 Heading G2J Visual images of X-ray photographs are recorded and reproduced by recording the image as a modulated diffraction grating and illuminating this record and selecting simultaneously diffraction intensities associated with the zero and one or more higher orders, adjusting the intensity ratios of the diffraction intensities and so projecting rays from those intensities that the image is reproduced as superimposed positive and negative. A pair of X-ray photographs 1, 2 Figs.1, 2 (not shown) are reduced photographically at 3, 4 and after spatial filtering give images 5, 6. These images are then recorded and printed at 7, 8 as image modulated diffraction gratings. These records 7, 8 are then illuminated and form images in spatial frequency planes 15, 16 in which are located diaphragms for passing the zero order and higher orders. The images are viewed through light attenuators, e.g. a device having three grey wedge sections which can successively be moved across the field of vision, each of graded intensity. An observer thus perceives a continuous transitions from negative to positive and back to negative. In a second embodiment, Fig. 4, 5, only the higher orders are used in reproducing an image. The spatially filtered images 5, 6 are used to each give positive 23, 25 and negative 24, 26 respectively on which are superimposed a diffraction grating. The grating may have the same constant but different azimuth angle for positive and negative 23, 24, whilst for positive and negative 25, 26 another grating is used. A single layer support 27 may carry all the exposures. To project the recorded images the support 27 is illuminated and a diaphragm 31 is located in the frequency plane of objective 30. The diaphragm has apertures (31a)-(31d), Fig. 6 (not shown) which passes the first order of each of the four superimposed images. A grey wedge disc lies over the apertures and is divided into three sections. The two outer sections over the apertures passing the first order of diffraction for each positive 23, 25 and the centre section overlies those apertures passing the first order of diffraction of negatives 24, 26. The density of inner wedge section increases in the opposite direction to that of the outer sections. A mirror arrangement permits binocular viewing, each eye respectively seeing a superimposed positive and negative.
