Title: Improved process for butt-welding metal parts and suitable insert for carrying out said process
IPC: B23K33/00
Filed: 1955-01-10
Abstract: 782,927. Welding by fusion. GENERAL DYNAMICS CORPORATION. Jan. 10, 1955 [Jan. 11, 1954; April 26, 1954; Dec. 10, 1954], No. 724/55. Class 83 (4). The adjacent edges of two metal parts 10, 11 Fig. 4, are butt welded by causing them to abut a. consumable metal insert 15 and displacing a welding torch along one face of the insert, the shape and composition of which are selected in such a manner that the amount of heat provided by the torch completely melts the insert and produces a weld having an almost smooth surface 53, Fig. 5, on the side of the parts 10, 11 opposite to that to which the heat is applied. The parts 10, 11 may be stainless-steel pipes and the material for the insert, which may be formed by milling out oppositely disposed sectors from a weld rod, may be selected by reference to a metallurgical diagram to produce a weld deposit containing 4 to 8 per cert ferrite. Air is dispelled from the interior of the pipes by an inert gas such as argon, and the insert tack welded at points such as 37. To melt the insert and cause it to fuse with the lips 16, 17 of the parts 10, 11 a root pass is made with an argon or helium shielded non-consumable electrode of tungsten or thoriated tungsten connected to the negative side of a D.C. source, the arc being held stationary until the initial weld puddle has an elliptical contour when the electrode is moved steadily, and preferably with a weaving motion, around the circumference of the weld channel 35. The puddles successively formed in this way are acted upon by surface tension, capillary action and adhesion to take up the shape shown in Fig. 5. The joint is completed by filling in the channel 35 with a number of cover passes, such as 56 to 58, made with a consumable electrode. The cross-sectional area of the rib 25, Fig. 12, of the insert and that of the flange 26 should have a ratio within the range of 0.1 to 1.5 while the dimensions should be in accordance with the formulµ W = r/k and h = r/k<SP>1</SP>, the value of k being greater than 0.6 and less than 3 and that of k<SP>1</SP> being greater than 0.5 and less than 3. The flange portion 26 may be of polygonal shape and the rib portion 25 shaped to suit straight chamfers on the edges to be joined.

Title: Interlocking device for the control of electrical systems
IPC: H02J9/06
Filed: 1935-01-10
Abstract: 453,765. Locking levers. ECLIPSE AVIATION CORPORATION, 545, North Arlington Avenue, East Orange, New Jersey, U.S.A. Jan. 10, 1935, No. 878. Convention date, March 13, 1934. [Class 80 (iii)] [See also Group XXXVII] Consists in interlocking means to prevent an improper sequence of actuation of switches controlling a number of circuits of an electrical system. The invention is described in connection with the electrical equipment of an aeroplane which includes a direct and alternating- current generator adapted to be driven mechanically or energized from a battery. The main field winding of the generator is shown at 4, and the commutator and direct-current exciting-field winding at 5, 6 respectively. The generator is driven normally from the engine through gearing 3, the collector rings 7 feeding the lights, radio apparatus, &c., a battery 8 being also provided. A second battery 10 is provided for initially exciting the machine and for energizing commutator 5 to run the machine as a motor-generator. The switches comprise brushes 12, 27 and pins 13, 14, on a plug 11 adapted to be inserted in sockets 36, 39 in a plug 38. The brush 12 is carried by an arm 22 integral with a sleeve 23 freely mounted on a shaft 24. This is provided at one end with an actuating level 25 and, at the other end, with an arm 26 carrying the brush 27 and a finger 42 adapted to engage the arm 22. The sleeve is also provided with a blocking arm 43 adapted to prevent entry of the pins 13, 14 into their sockets when switch 12 is closed as in Fig. 1. If now the lever 25 be moved counter-clockwise, switches 12, 27 are both opened and, arm 43 being out of the way, plug 11 can be engaged with plug 38. With the plug in closed position, current from battery 10 flows to rheostat 37 and winding 6 to excite the machine, the return being by way of 44, 45, 39, 14 and 16. One end of a torsion spring 49 bears against a pin 51 on arm 22, the other end bearing against an abutment 52. This spring returns arm 22 to the closed position, Fig. 1, whenever arm 43 is free to move. It will now be seen that, by moving lever 25, the switch 27 may be closed whilst 12 is still open, the arm 43, Fig. 2, being blocked by plug 11. This position produces a current flow from battery 10 to commutator 5. After the initial energization, the switch 12 may be closed to throw the load on the machine by withdrawing plug 11, thus cutting out battery 10, and releasing arm 43 whereby arm 42 and switch 12 are urged by the spring 49 to the closed position.

Abstract: 175,864. Berridge, H. C. Jam. 8, 1921. Transmission mechanism, special applications of; regulating.-A windmill is provided with a transmission gear for driving a reciprocating water-pump, or in a modified form for general power purposes. The gear comprises essentially a disc on the windmill shaft provided with eccentric cam-grooves of circular or other shape into which project members attached to the pumprod so that the lift is first rapid and then slow. Regulating gear for the windmill is also provided. The disc 10 on the windmill shaft 2 is provided on each side with a circular groove 11 in which engage rollers 15 on links 14 connected to a rod 13, which has a swivel connection 17 with the pump-rod. The links 14 are guided by roller projections 16, which move in vertical guides 12 fixed to the rectangular frame 7. The hollow mast tube 5 carries the frame 7 and is provided at its base with a ball thrust bearing, which is thus readily accessible. The grooves 11 are eccentric to the disc 10, which may be provided with a balance weight 18. Although the grooves 11 are of semicircular shape for the position causing the lift of the pump-rod, the return portion may be of any shape, but a complete circular form is satisfactory. The disc 10 may have a toothed periphery or is otherwise constructed for driving a dynamo mounted on the frame 7 or for transmitting power for other purposes. For regulating purposes, the windmill tail 19 is pivoted on the frame 7, and is connected from an extension of the tail beyond the pivots through links 27 - - 32 to a band brake 23 on the wind-wheel shaft. If the tail moves slightly out of the wind the brake is gradually applied, and if it is swung by a gale approximately parallel with the plane of the wheel the band brake is strongly applied to stop the wheel and prevent wrecking. The tail may be forcibly moved over into this stopping position against the action of a spring 21 by means of a chain 33 attached to the tail and passing round pulleys 35 to a sli'ding-collar 36, which is operated by connections 37, 38 from the foot of the tower when it is desired to place the windmill out of action.

Abstract: 413,294. Pneumatic separating. ALLEN, R. H., 19, Makepeace Avenue, Highgate, London. Jan. 11, 1933, No. 975. [Class 117.] In apparatus for separating dust or fine particles from a mixture of particles of different sizes, of the kind which comprises an elongated sloping separating chamber, the lower side of which has apertures for the entrance of air or other gas, which carries away the finer particles from the mixture as it slides thereover, the lower side 2 of the chamber 1 is curved with the convex side uppermost. Preferably the radius of curvature increases from the top to the bottom so as to approximate the path of freely falling material and the feed shoot 7 is tangential to the upper end of the side 2. The air is introduced under the side 2 by a conduit 11 with a regulating valve 12, and a baffle 13 may be provided for regulating the distribution of the air as between the upper and lower parts of the side. A supplementary air current may be introduced at the bottom end 9 of the chamber by means of the conduit 14 and valve 15, and a baffle 16 may be provided in this conduit for smoothing the flow of air. In the construction described, the side 2 is formed of overlapping metal plates which may be adjustable and be provided with air-directing wooden blocks 3, 4. The top side 41 of the chamber is curved to follow generally the contour of the lower side but is preferably spaced at an increasing distance therefrom towards the upper end of the chamber, and provided with a manhole cover 21 and inspection window 22. The lower discharge end of the chamber is provided with baffles 19 to break the fall of the dedusted material and rubber linings may be provided for the plates 2, and the inlet and outlet ducts of the chamber. The dust laden air passes up the conduit 8 into a classifying duct 23 in which an intermediate grade of particles is deposited either for separate removal or return to the separating chamber. This duct may be curved as shown and the upper side is formed of two hinged interleaved plates 24, 25 which are adjusted in position by a screw 28 to vary the cross-section of the duct. Deflectors 31 are provided on the lower side of the duct to guide the deposited material to the corners of the duct out of the main air current. The air from the classifier is passed through dust settling apparatus such as described in Specifications 411,121, 411,122, and 411,123, and may be returned to the fan in a closed circuit or into the atmosphere. Air flow indicators may be fitted at required points, and the apparatus may be associated with a device for screening out the large pieces from the raw material. When damp material is being treated, heated air or gas is used and discharged into the atmosphere.

Date Apr. 6, 1989.In a process for transfer pattern printing of a moist textile web consisting wholly or predominantly of natural fibers, in particular cotton, and/or artificial fibers on the basis of cellulose, the pattern carrier web is a web of paper or a paper-like material which carries a pre-printed pattern of a water soluble or dispersable dye. After wetting of the textile web to a carefully controlled moisture, the textile web is joined with the pattern carrier web and the joined webs are compressed at a suitable pressure so that the pattern can be transferred without using heat. The advantage is that it will be possible to avoid both heating and use of organic solvents. It is also possible to transfer a pattern to a colored textile web since the textile web may be wetted before hand with an aqueous dye solution or dispersion instead of undyed liquid.
