Title: Improvements relating to stop collar assemblies
IPC: E21B37/02
Filed: 1953-05-11
Abstract: 721,100. Stop collar assemblies for drill pipes &c. HALL, J. E. May 11, 1953, No. 13139/53. Class 85. A stop collar assembly for a drill pipe or well casing consists of a sleeve 10, having inclined surfaces extending inwards from the mid section to the edges thereof, and a circular coil spring 11a,  11b which wedges between one or the other of the inclined surfaces and the outer surface of the drill pipe, dependent upon the direction of an initial relative movement between the pipe and the collar, to secure the collar to the pipe. The circular coil spring consists of two coupledtogether sections 11a, 11b, and, during the positioning of the collar on the pipe, the said spring is expanded clear of the pipe by a spreader coil spring 13 which has its coils removably intermeshed with those of the shorter section 11b of the circular spring. The spring 13 is longer than the spring section 11b so that the ends 13a do not intermesh with the section 11b, and when the coil assembly is placed in the sleeve 10 the ends 13a project through apertures 10a therein. A wire 14 projects through one of the apertures 10a and is threaded through the spreader coil 13 and spring section 11a to prevent them becoming accidentally disassociated. To secure the collar on the pipe, the wire 14 and the spreader coil spring 13 are withdrawn through the apertures 10a whereupon the circular coil spring contracts, gripping the pipe and being wedged between one of the inclined surfaces of the collar and the pipe on relative movement occurring between these parts.

Title: Improved fluxes and flux coated electrodes for electric welding
IPC: B23K35/36
Filed: 1937-05-07
Abstract: A flux for use with welding electrodes, e.g. as a coating applied directly to the bare electrodes, contains iron oxide, silica, and starch, the starch constituting 4-20 per cent by weight of the flux. For example a flux comprising 35-45 per cent of iron oxide, 20-30 per cent of silica, 10-20 per cent of ferromanganese, 5 per cent of clay, and 15 per cent of starch may be made into a paste with sodium silicate or gum arabic and applied to an electrode by extrusion.  The coating is hard, fuses readily, and during welding the starch gives rise to a blanketing atmosphere which localises and intensifies the heating effect. The presence of starch in the proportions specified also has a marked effect on the arc voltage.

Abstract: 593,261. Making bearings. HAY. WARD, TYLER, & CO., Ltd., HOWARD, G. P. E., and IVANOFF, V. May 28, 1945, No. 13305. [Class 83 (ii)] [Also in Group XXXIV] A tilting pad 1 for an end thrust bearing has its side opposite the bearing surface 3 out away or stepped to provide the tilting edge 4. The stepping is not carried completely across the pad, so that the pad can be rested firmly on this side during production, and, if of magnetic material, held there by magnetic attraction. If magnetic attraction is not used, undercut side recesses 8 are provided to be engaged by the heads of screws. The supporting ring 2 is made considerably narrower (radially) than the pads, and the stepping is carried across the middle of the pad no further than is necessary to traverse this ring. A channel-shaped recess 5 is thus formed. In a modification, the pad is formed at each end with a lug 6 of reduced depth, having a notch 7 in it for locating screws, so that the bearing surfaces 3 will be proud of the screw-heads. A common screw, fitted loosely to allow for tilting, engages in the notches of two adjacent lugs. When lugs are used, the stepping may be carried right across the pads.

Title: Improvements in and relating to mastic asphalt compositions
IPC: C08L95/00
Filed: 1936-05-11
Abstract: A bituminous composition comprises cement, a bituminous emulsion of the mixing type and added water, the volume of water in the composition exceeding that of the cement and being at least 15 per cent of the volume of bitumen and aggregate in the mixture. Preferably the cement is first mixed with water to form a slurry, the slurry is mixed with the emulsion, and then aggregate and more water are added.  The water used in preparing the slurry may be at least 50 per cent by volume of the cement. Five examples are given, of which the following is typical: (parts by volume) Portland cement 6, bituminous emulsion (containing 55 per cent of bitumen) 15, water 10,46, "bluestone" (basalt) aggregate 40.  The aggregate may be sand, crushed slag, bricks, tiles, clinker, burnt clay, limestone, granite, gravel, cork, sawdust or rubber.  The volume of added water may be at least 50 per cent of the volume of the emulsion.  The emulsion may contain between 45 and 65 per cent of bitumen.  The composition may be (1) mixed with more, relatively coarse aggregate, and may be of such a consistency that when the mixture is laid as a roadway the coarse aggregate sinks to the bottom; or (2) applied to a recently-laid, soft, cement concrete roadway or other surface, thus binding with the latter; or (3) laid as a roadway, coarse aggregate being then lightly scattered thereon and pressed into the surface thereof to form a hard, mosaic-like finish.

Abstract: 603,164. Joining metal plates etc; walls; floors. DETROIT STEEL PRODUCTS CO. May 28, 1945, No. 13370. Convention date, June 7, 1944. [Classes 20(ii) and 20 (iv)] Relates to metallic building structures, and comprises the prefabrication from sheet metal of units which may be assembled to form the flooring, roofing and walls in such a manner as to facilitate the installation of conduits and wiring. Fig. 2 shows two units assembled together. Each is formed from a wider sheet 5 and a narrower sheet 4, parallel to one another, and spaced apart by stiffening webs 6. One edge of the wider sheet 5 has a curved flange 12, and the opposite edge has a plain flange 9. Both the flanges at the edges of the narower sheets 4 are curved. The plain flange of the wider sheet of one unit engages in the curved flange of the wider sheet of an adjacent unit, the units thus being joined with their faces in flush relation Owing to the top sheet being narrower than the bottom a channel is left between the web members of adjacent assembled units, which may be used for wiring, as shown in Fig. 4. The channel is closed by a cover 3, the edges of which have plain flanges which engage in the curved flanges at the edges of the narrower sheets of adjacent units. Interlocking means are provided by the bosses 15 on the plain flanges of both the covers and the wider sheets, the opening of the curved flanges having a width such as to require the springing of the flanges into engagement. Economy of material may be effected by making the sheets 4 and 5, the web member 6, and the cover 3 of different gauge material, according to the relative stresses therein under load. Reverting,to Fig. 4, the ends of the units are in alignment, and the adjacent ends of the web members 6 are cut away at 17 to receive a trough 19 which extends transversely of the units, and which is closed by a cover plate. The side walls of the troughs are provided with plugs for the passage of wiring into the channels of the units. Plates 23 may be made in the covers 3 for the passage of the wiring through the flooring 21, 22. The units may be assembled to form a wall, as shown in Fig. 7, and may contain sound-deadening materials as insulation 33. Fig. 7 also shows an arrangement for completing the flooring when the width between the opposite walls is not a multiple of the width of the units, employing a starter unit 27 of less width than the standard units. The sheets and covers may be perforated if desired, and the sound deadening material may be spaced from the sheets on grids. The sheets under compression may be ribbed in various ways, as shown for example in Fig. 9. Fig. 15 illustrates the unit with its narrower sheet 49 and also its cover 50 each formed with a depressed rib 51 which forms a groove for the nailing strip 52 having its outer face flush with the outer faces of the sheet and cover.

Class 83 (4) A frame welding burner has means for automatically feeding filler metal coaxially through the burner nozzle in a longitudinal sleeve and co-axially through the flame to the welding zone. A pistol type burner comprises a casing 1 having a grip 3 and shield 5 and a nozzle 6, 7. Gas is supplied from a mixer 15 through a conduit 16 to concentric passages 10, 4-6 in number, and filler wire 83 is fed through a central sleeve 9 within the nozzle 6, 7, the gas converging on the wire ¢ inch from the nozzle. An external flexible connection from, e.g. a series D.C. motor, drives a shaft 17 carrying a gear 20 engaging a wheel 21 to rotate a frusto conical drum 31 through a universal joint 26. A wheel 32 driving a worm 37 through a universal joint 35 is rotated by the drum 31 when a trigger 4 is pressed to allow a spring 77 to pull the wheel 32 into contact with the drum 31. Release of the trigger 4 lifts the wheel 32 from the drum 31. The worm 37 drives wheels 45, 46 mounted on shafts 43, 44 to rotate wire feed rollers 41, 42 between which the wire 83 is fed. Pressure on a spring held lever 58 swings the shaft 44 about the axis of the worm 37 to move the rolls 41, 42 apart. Rotation of a knurled scroll wheel 60 causes longitudinal movement of a unit comprising the drum 31 and wheel 21 and thus adjust the speed of rotation of the wheel 32 and of the rolls 41, 42. The filler wire may be in short rod, wire or strip form and may be flux or wash coated or may have a flux core. The concentric nozzle passages may be replaced by an annular passage. The burner may be a head attached to a carriage for fully automatic welding.
