Title: Improvements in or relating to bifurcated tube fittings
IPC: B21C37/28
Filed: 1962-01-19
Abstract: 983,005. Pipe couplings. BABCOCK & WILCOX Ltd. Jan. 19, 1962 [Jan. 19, 1961; March 13, 1961], No. 2013/62. Heading F2G. [Also in Division B3] A bifurcated tube fitting for connecting two parallel tubes comprises a forged or stamped body of generally cylindrical form closed at one end, and at the other end formed with a pair of spaced parallel passageways. Alternatively, the closed end may be formed with a nozzle for connection to a third tube. Such a fitting may be made by pressing a disc between a die and a forked punch to the shape shown in Fig. 2. Further pressing in another die and the welding on of a cap 4 produce the fitting 1B of Fig. 3, to the passageways 2 and 3 of which tubes 6 and 7 may be welded. In a modification a cylindrical blank is machined and forged to the shape shown in Fig. 5 and formed with small bores at 13 and 14 to define the centres of the desired passageways. It is then stamped as before, Fig. 7, tubes 17 and 18 welded on and the tubes and passageways 16, 16A, are brought closer together by means of bars 19, 20 which are inserted, pressed together and then withdrawn. The upper end of the fitting may be formed with a nozzle 21, Fig. 8, or closed by a cap. During pressing, the fitting may be formed with external ribs 22, 23 and the tubes 17, 18 may have corresponding ribs 22A so that the ribs of adjacent sets of fittings form a wall which can be made fluid-tight by welding the adjacent ribs. Deflector means may be enclosed within the fitting before closing the end or forming the nozzle. The initial shaping of the fitting may be carried out in the two-piece die shown in Fig. 11, comprising an upper cupshaped recess 31 and a pair of parallel spaced bores 32A, 32B separated by an upstanding portion 34 with a recess 35 for thickening the wall at the crutch. A forked punch 37 cooperates with the die. The length of the passageways of the fitting is determined by movable spacers 36 placed in the bores of the die.

Title: Production of cinematographic effects in colour and means therefor
IPC: G03B33/00
Filed: 1933-01-21
Abstract: 414,059. Colour kinematography. HILLMAN, A. G., JOHNSON, G. H., and COLOURGRAVURE, Ltd., Victoria House, Vernon Place, Southampton Row, London. Jan. 21, 1933, No. 2049. [Class 97 (i).] A kinematograph camera for producing a negative band of colour constituent images in which each negative is exposed once with the preceding negative and again through the same or a like colour filter with the following negative as described in Specification 414,065, has a light dividing system composed of plane non-refracting reflectors and co-operating matched lenses, the reflectors being mounted for relative rotation about an axis or axes parallel to the plane of the film gate and fine adjustment means being provided to angularly adjust the reflectors to effect even spacing of the images along the length of the film. As shown in Fig. 9, the entering beam 5 forms a direct beam passing through the medially apertured reflector 6 and lens 3 to the film gate 9 and a branch beam passing by the imperforate reflector 7 and lens 4 to the film gate 9<1>. The reflectors 6, 7, which are of stainless steel are rotatably mounted about axes 34, 35 and can be angularly adjusted against the tension of springs 38, 39 by adjusting screws 36, 37. Means is provided for adjusting the alignment of the axes 34, 35. The reflector 6 may have a number of inclined apertures as described in Specification 404,307. Standard width film and standard picture pull are employed in the camera. Fig. 5 shows means for effecting appropriate change of colour filters. The half speed shutter 13, of which the effective part moves in a direction opposite to that of the film feed, carries a crank pin 16 connected to a sleeve 19 slidably mounted on a rod 20, pivoted at 18. The rod 20, which is thus caused to rock in synchronism with the shutter, carries a sector 15 supporting a central filter 11 of one colour (say red) and marginal filters 12, 121 of another colour (say green). In operation, a negative is exposed for the first time through the red filter 11 in gate 9 whilst the preceding negative is exposed for the second time in gate 9<1> through the green filter 12. It is then re-exposed after one picture pull through the red filter 11 in the gate 9<1> whilst the following negative receives its first exposure in the gate 9 through green filter 121. The camera may have means to expose an identity mark on the margin of every other picture, e.g. the red record pictures, in order to facilitate the joining of positive films produced from the negative.

Abstract: 573,957. Oscillation - generators. GENERAL ELECTRIC CO., Ltd., and JAMES, E. G. Feb. 11, 1943, No. 2322. [Classes 40 (iii) and 40 (v)] An oscillationgenerator comprises a grid-controlled thermionic tube arranged so that the space between two of its electrodes, e.g. the grid 6 and anode 5 lies within a wave guide and the electrodes are continued by the walls of the guide which is so dimensioned that waves of the fundamental mode in which the tube oscillates are greatly attenuated and oscillations of a harmonic frequency are effectively generated. As shown, the anode is continued outside the wall of the tube by a disc 5<1> which forms a part of a wall of the guide and the grid is continued by a disc 6<1> which is bent to fit an aperture in a re-entrant part of the guide formed by the end of the outer conductor of a coaxial line 10. The fundamental frequency of oscillation is determined by the grid-anode capacity of the tube, an adjustable plate 13 and the inductance of the connection 7 between the grid and the anode constituted by a portion of the walls of the guide and that of the electrodes themselves. The guide itself has piston tuners 4 and oscillations of the harmonic frequency are taken off by a probe connected to a wire 3. The line 10 to which the grid and cathode are connected has a tuning bridge 12.

Title: Compacts of finely divided material and method of forming same
IPC: C01B32/942
Filed: 1957-01-23
Abstract: In the production of calcium carbide an aqueous solution of calcium formate is used as a binder for lime hydrate and a carbonaceous reducing agent, the mix being compacted into pellets that are resistant to abrasion and disintegration.  In an example, lime hydrate, soft coal, and saturated calcium formate are mixed to a paste, extruded into pellets 1/4 inch by 1/2 inch and dried at 125 DEG  C.  They are then calcined in an arc furnace to produce calcium carbide.  In another example, lime hydrate deriving from acetylene generation is alone bonded by calcium formate solution, formed into pellets, and calcined at 950 DEG  C.ALSO:In the production of high carbon ferroalloys an aqueous solution of calcium formate is used as a binder for ferromanganese or ferrochromium ore and carbon, the mix being compacted into pellets that are resistant to abrasion and disintegration.  In two examples mixes of soft coal, saturated calcium formate solution, with (a) Indian Mn ore and calcined MgO, and with (b) Transvaal chromium ore, lime hydrate and silica flour, are extruded into pellets, dried at 125 DEG C., and charged into an arc furnace to produce high carbon ferromanganese and ferrochromium.ALSO:Compacts of finely-particulated reactant material that are resistant to abrasion and disintegration are made by admixing the material with an aqueous solution of calcium formate and then compacting and drying the mixture.  The calcium formate, which may be in saturated or unsaturated solution, preferably forms 2 to 6% by weight of material, and the mix is suitably extruded or compacted into pellets or briquettes of less than 3/4 inch in diameter which are then dried at about 125 DEG C.  Two applications are described: in the manufacture of calcium carbide, lime hydrate is mixed with a carbonaceous reducing agent and calcium formate, and in the production of high carbon ferroalloys, ferromanganese or ferrochromium ore and carbon are mixed with calcium formate.  In an example, calcium formate solution is employed as a binder for lime hydrate alone.

Abstract: 1,094,984. Copying by scanning. JARROLD & SONS Ltd. Jan. 20, 1965 [Jan. 21, 1964], No. 2498/64. Heading H4F. [Also in Division G2] A copy of an original (opaque or transparent) is made by scanning with a laser beam. In the simplest form, the beam passes directly through a transparent original to a photosensitive sheet, which may or may not be in contact with the original. In the arrangement illustrated, an image of a transparent or opaque original is projected along a path 5 from a projector 4, and reflected by mirrors 1 and 6, to fall on a screen 7 having a small aperture 8. Behind this is a photomultiplier 9. Mirror 1 is fixed on a rotating shaft 2, and mirror 6 can oscillate as indicated by the arrows. Thus the two mirrors, acting in combination, can scan the image of the original line by line across the aperture 8. A beam of light 5<SP>1</SP> from a laser 10 passes through a focusing system 11 and a light-modulating device 12 (Kerr cell or crystal modulator), and is reflected from a mirror 1<SP>1</SP> to fall on a sheet of photographic material 13. Mirror 1<SP>1</SP> is also mounted on shaft 2, and thus rotates in synchronism with mirror 1. Sheet 13 is given an oscillating motion in synchronism with mirror 6, and thus the beam 5<SP>1</SP> carries out a line by line scanning movement across sheet 13 corresponding to the scanning of beam 5 across aperture 8. The signals received by photomultiplier 9 are fed through an amplifier 16 to the modulating device 12, so modulating the laser beam. Thus an exposure is made on sheet 13 corresponding to the original. A screen may be placed over sheet 13 to produce half-tone effects. By using suitable colour filters 14, separate colour records may be made

Abstract: 843,344. Gas turbine plant. DOWTY FUEL SYSTEMS Ltd. April 17, 1958 [Jan. 23, 1957], No. 2506/57. Class 110 (3). A fuel supply system comprises a main pump 4, delivery control means 5 and a circulating pump 6 supplying fuel to the inlet connections of the spill nozzles 1 and fed with fuel from both the main pump and the spill connections of the nozzles, the arrangement being such that at lower fuel discharge rates fuel enters the nozzles only through the inlet connections, while at higher fuel discharge rates the fuel enters the nozzles through both the inlet and the spill connections. To prevent fuel flowing to the nozzle along the spill flow line 3 during the starting of the engine a valve 8 is provided in the line 3. The valve comprises a mushroom valve element 14 spring loaded on to its seating 13 and provided with a stem sliding in a bore 15 which is in communication with the outlet of the circulating pump. When the engine has reached its normal operating speed the fuel pressure is sufficient to raise the valve element 14 against the pressure of its spring 16 and hold it open to allow a flow of fuel in either direction along the spill flow pipe. According to the Provisional Specification the valve 8 may be a manually operated valve.

Apparatus for welding together parts of a crank-shaft using a submerged arc-welding head positioned above the joint to be welded, rotates the crank-shaft at a speed related to the number of deposited layers of weld so that the peripheral speed of the weld surface remains substantially constant as the joint is filled up. At the same time the welding head is moved away from the axis of rotation of the crankshaft. The crank-shaft 9 is supported on rollers 2 as described in Specification 893,356, and the welding head 5 is mounted on a beam 4 movable longitudinally of the crank-shaft to deposit beads side-by-side in the joint as is described in Specification 893,357. A motor 6 rotates the crank-shaft through a variablespeed device 7, providing continuous or stepby-step variations under control of a gear 11 driven by a gear 30 connected to the motor 6, so reducing speed as the welding progresses. The welding head 5 is moved vertically on its slide by a threaded rod 26 and nut 27 or a rack and pinion through a shaft 16 carried on the beam 4 and driven by the motor 6. If the head 5 is moved longitudinally of the crankshaft to lay a second bead, the speed is automatically increased and the head 5 is lowered. When a joint is welded the welding head 5 is traversed along the beam 4. The operation may be controlled by an electronic, hydraulic or other programmer.
