Title: Improvements in or relating to welding fluxes and welding rods coated therewith
IPC: B23K35/36
Filed: 1944-09-05
Abstract: A flux for welding, preferably for electric arc welding of light metals and/or with welding rods of light metals, especially aluminium or aluminium alloys, is characterised by the following composition or an analysis corresponding thereto: Lithium chloride 5-25 per cent, sodium chloride 10-30 per cent, potassium chloride 20-40 per cent, potassium fluoride 5-20 per cent, sodium-aluminium fluoride 5-20 per cent and, if desired, a small amount of alkaline earth fluoride, e.g. calcium fluoride, not exceeding 10 per cent.  The flux may also contain up to 20 per cent of ammonium halide.  The flux is preferably non-hydrous. Welding-rods coated with the flux may be made by suspending the flux in a substantially non-hydrous volatile organic liquid, for example, petrol, benzene, acetone, methyl alcohol, ethyl alcohol or mixtures of these, and applying to the rod in any desired way, such as dipping or pressing.  The coating is then dried at an elevated temperature, e.g. 50-100 DEG  C. or higher, and the suspension medium may be recovered on evaporation.  Preferably, the coated rod is given a moisture-proof layer of a substance, non-carbonizing at the welding temperature, for instance, a lacquer layer, as of cellulose acetate, nitrocellulose, celluloid lacquer or shellac.  Specification 598,090 is referred to.

Title: Improvements in and relating to distillation processes
IPC: B01D3/14
Filed: 1946-06-05
Abstract: <PICT:0621801/III/1> To minimize the effect of sudden fluctuations in continuous distillation in which the feed stream is introduced at an intermediate point 4b in the column 1, a side stream of liquid is taken off at approximately the same level 5 as the feed point and transferred to a vessel of comparatively large capacity 9, initially holding liquid of the same composition as the normal side stream, from which liquid is removed at the same rate and returned via valve 11a to the feed stream or to a point in the column at approximately the same level as the feed point, i.e. not more than 2 plates away. The rate of withdrawal of the side stream is usually from 10 to 50 per cent of the supply of the original feed stream and the vessel may hold from 5 to 8 times the hourly amount of feed stream and heat losses are minimized by lagging.  The column may be a plate column or a packed column, the latter being provided with a receptacle inside the column from the bottom of which the side stream is led off.  The process is exemplified by reference to the separation of methanol and water and to the separation of nitro-paraffins, e.g. the nitropropanes, or of other mixtures for which no simple and rapid chemical methods of separation or estimation are available. Reference is also made to the advantages of the process in distilling mixtures whose composition is liable to vary during the process and the process is applicable to distillation at atmospheric, sub-atmospheric or super - atmospheric pressures.  Specification 446,137 is referred to.

Title: Improvements in and relating to delivering dough pieces to baking tins for making bread
IPC: A21C9/08
Filed: 1947-06-30
Abstract: 632,399. Moulding tin loaves. PALMER, A. R., and BAKER PERKINS, Ltd. June 30, 1947, No. 17150. [Class 87 (ii)] In the manufacture of tin bread wherein successive pairs of dough pieces are fed to lie or edge in a tin 5, each successive pair being positioned after a stepwise movement of the tin, the dough pieces of each pair are delivered in timed relation such that the dough piece of each pair which lies towards the leading end of the tin arrives in the tin in advance of the other piece of the pair. Dividing means 1, 2, preferably of the kind described in Specification 571,563, deliver pairs of dough pieces in parallel to flattening rollers 3a, 3b and 4a, 4b. The rollers are driven by a chain 6, the driving sprockets of the rollers 3b, 4b being of smaller diameter than those of the rollers 3a, 4a so that the former revolve faster and cause the dough piece passing through them to be discharged in advance of the other piece of the pair. Alternatively, the same effect can be obtained by making the rollers 3b, 4b of greater diameter than the other pairs of rollers, all rollers being driven at equal angular velocity. 'The pieces are guided into one of a series of tins 5 by angularly adjustable chutes 9, 10 which are preferably of the type described in Specification 620,724, [Group XXX], having transverse slots for the passage of an air blast. The inner roller of the pair 4b is displaceably mounted, e.g. on a lever 19 so that the passage of a dough piece causes it to move outwardly and to raise, by means of levers, rods, etc., 21-27, a lever 28 pivoted at 29. This causes a pawl 18 pivoted to the lever 28 at 39 to disengage a ratchet 17 and allow conveyer chain 15 carrying the tin 5 to move forward one step. Engaging a detent 30 on the pawl 18 is a sear 31 which is also mounted on the lever 28 and is normally urged into the position of engagement by a spring 33. The sear 31 has a bevel surface engaged by one end of a rod or trigger pin 35 the other end of which abuts a fixed stop 38. When the lever 28 rises, the trigger pin 35 bears on the bevel surface of the sear 31 and pushes it out of engagement with the detent 30 leaving the pawl 18 free to be pulled down by a spring 32 into engagement with the next tooth of the ratchet 17. After the dough piece has passed the displaceable roller 4b it moves back to its normal position and allows the lever 28 to descend urged by spring 35a. The lever 28 may be laterally slidable to bring into use alternative pawl and ratchet mechanism 18a, 17a, Fig. 2, so that the tins may be stepped in a manner suitable for dough pieces of appropriate weight for either a 11b. or 21b. loaf. Specification 400,619, [Group VI], also is referred to.

Title: Improvements in equi-signal radio direction finder systems
IPC: G01S1/02
Filed: 1940-12-02
Abstract: 569,435. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and SMITH, S. B. Dec. 2, 1940, No. 17162. [Class 40 (v)] An overlapping beam transmitter comprises a source 1 of the three-phase energy, the rectified energy from one phase being applied to a locked pulse trigger system 5 to effect energisation of an aerial 13 driven by a carrier source 9, while the other two phases are applied to a locked pulse trigger system 6 to energise an aerial 14 in a similar way. Thus in the area 16 there will be the two pulses 1, 3 while in area 15 there will be the single pulse 2 all the radiated pulses being equal and equally spaced. Along the equi-signal path will be received a signal comprising pulses of equal amplitude while on either side either the single pulse or the pair of pulses will be of greater amplitude. A receiver is described in which the signal is applied to one pair of plates of a cathode ray tube while to the other pair of plates is applied a scanning voltage whose period of sweep includes one set of three pulses. This gives a stationary figure on the screen which for equi-signal shows three marks of equal amplitude. The scanning voltage may be locked by the incoming impulses. Although described for a threeimpulse.. system, a larger number of pulses forming interlaced signals may be employed.

Title: Improvements relating to variable speed transmission gear
IPC: F16H15/12
Filed: 1926-07-15
Abstract: 270,919. Chandabhoy, N. K. N. July 15, 1926. Addition to 243,302. Variable-speed and reversing friction gearing according to the parent Specification is modified so that there is a direct drive between driving and driven shafts 21, 106, Fig. 2, through a clutch 105, and modified also so that it may be possible to change speed without disconnecting the drive. As before, a disc 20 is pressed by a spring 108 against splined rollers 18, 19 which are movable by the power of the engine to change speed. Reversal on any speed is effected by moving a double clutch 10 by means of a lever 25, Fig. 1, locked by a fork 37. Screwed traversing rods 45, 46 in pairs are turned from the engine when either of two gears 54, 56, Fig. 5, is meshed with a gear 79 constantly driven from a sprocket 3, Fig. 2. When the rollers 18, 19 are closed inwards to increase the speed, they pass into a hollow 20<a> and so clear the disc 20. They then strike the outer edges 110,112 of a spring toggle frame 118 which is thus expanded so as to thrust the clutch member 105 relatively to the gear 6 with which it turns into engagement with the boss of the disc 20. The improved control means for the variable friction gearing comprises a chain 130, Fig. 1, attached at one end to a pivoted lever 129, passing over a pulley 130' on gear-control yoke 41, and attached at the other end to a slidable frame 57, Fig. 5, carrying the spaced control gears 54, 56. The lever 129 is connected by linkage 127 with a control lever 126, which can move over a quadrant 104 or can be looked thereto and turn the quadrant with it. To effect a direct change down, the lever 126 is moved over the quadrant so as to shorten the chain 130 by the required amount. The lever is then locked to the quadrant so as to turn barrel 104<b> about its axis and through a lever 104<a> move the frame 57 so as to commence the power change. When the required speed is reached, the chain 130 is tightened by the yoke 41 and the frame 57 is jerked to disconnect the gear 79 and stop the changing operation.

Title: Improvements in material conveying plant
IPC: B65G65/00
Filed: 1940-12-17
Abstract: 545,914. Feeding conveyers from hoppers. BABCOCK & WILCOX, Ltd., and TAYLOR, R. A. Dec. 17, 1940, No. 17754. [Class 78 (i)] Means for controlling the gravity feed of material from a hopper to an endless conveyer comprises a shoot arranged between the hopper and the conveyer and extending downwardly from about the level of the hopper outlet in the direction of movement of that part of the conveyer adjacent the discharge end of the shoot, the shoot being adjustable or movable to and fro relatively to the hopper in the said direction. The shoot thus protects the conveyer from material falling from the hopper, and the adjusability of the shoot enables the rate of flow from the hopper to be controlled. In the construction shown in Figs. 1 and 2 applied to a hopper 1 feeding a reversible endless belt conveyer 2 two shoots, 5, 6, having oppositely-sloping bottoms 28, 29 are provided, one for each direction of movement of the conveyer belt. The shoots are fixed together and comprise side plates 7 secured to longitudinal channel members 10 resting on rollers 15 mounted on a frame 16 secured to the hopper. Thus the shoots can be moved on the rollers until either one is beneath the hopper outlet 31. The shoots are fixed in any desired position by means of a pin 25 inserted in a hole in the hopper frame 19 and in any one of a number of holes 27 in a member 24 secured to one of the shoot channels 10. In the position shown in Fig. 1 material from the hopper falls directly on to the bottom plate 29 of the shoot 6 and from there passes on to the conveyer belt. If the shoot is moved to the left the rate of flow increases and vice versa. Wear plates 8, 35 are provided on the sides and bottoms of the shoots. The flow of material may be stopped when desired by means of a removable plate 45. In a modification Fig. 3, not shown, the shoot bottoms instead of forming an inverted V are connected at the top by a horizontal plate so that when this plate is beneath the hopper outlet it stops the flow of material. In the construction shown in Fig. 6 the bottom of each shoot is formed by bars 41 spaced apart to allow fine material to pass through directly to the conveyer belt, large pieces of the material passing down the bars to the shoot outlet and falling on to the ,layer of fine material already deposited on the conveyer. The bars are welded to transoms 42 which are concave on their upper surfaces so as to tend to cause the lumps of material to be deposited near the centre of the belt.
