Title: Improvements in or relating to electric-arc-welded joints
IPC: B23K33/00
Filed: 1941-09-10
Abstract: 548,992. Uniting by fusion. MOSS, J. A. Sept. 10, 1941, No. 11597. [Class 83 (iv)] In electric arc welding the faces 1, Fig. 1 to be welded may be first provided with one or more interfaced layers of weld metal 3 and then with one or more deposited beads 2 of weld metal, the beads projecting from and extending longitudinally of the interface layers to define the root or base of a welding groove. In a modification for wider gaps between the faces one or more beads 2a, Fig. 8, may be directly deposited on the faces of the parts and one or more beads 2b are then deposited on the first beads to define the base of the groove. In a further modification, Fig. 6, for high speed welding of thick plates, beads are deposited directly on the faces 1 of each part, the beads extending substantially across the thickness of the faces and forming a constriction at each side constituting the base of the welding groove. The bead metal or alloy may be the same or different from that of the parent metal or weld filler metal. The parent metal may comprise wrought or cast iron or carbon or alloy steel. When the beads are provided on both faces they are arranged to coincide. The faces 1 of a butt joint may be at right angles to the surfaces of the plates with the beads 2, which may be continuous or staggered, arranged adjacent one edge or at any intermediate point, or may be bevelled to produce a V or double-V gap, the beads being arranged at the narrowest point. The interface layers may be of uniform thickness or may be of variable thickness so as to provide the constriction 4. The layers may be of a metal or alloy different from the parent metal. A metal plate of high carbon steel may be coated with one or more layers of soft mild steel and the weld filler metal may be of high tensile alloy steel. Corner, fillet or T joints may be similarly effected. The beads may be ground, filed or machined after deposition.

[Class 52 (ii)] The back and seat frames of a chair are pivoted together and to the main side frames, the back near its lower end and the seat near the front end and the pivot members of the back and seat in the side frames are adjustable vertically. Side frames 1, 2 built up of channelsection metal pressings are spaced apart by front and rear members 6 and diagonal stays 7, 8. Seat and back frames 3, 4 hinged together at 60 are pivotally supported by transverse bars 11, 12 carried by parts 15, 16 slidable in members 25 secured to vertical parts 14 of the side frames and provided with racks 26 with which engage cross-pins 29 on spring-urged rod 27 slidable in the bars 11, 12 whereby these bars may be supported at various heights. The pins 29 are disengaged from the racks by a plate 32 which bears on a roller 31 on the rod 27 and is caused to move inwards as it is moved upwards, by engagement of inclined slots 35 therein with fixed pins 34. The plate 32 for the bar 12 is operated by a press-plate 36 pivoted at 37 to the side frame 2 and connected to the plate 32 by linkage 39-44. The plate 32 for the bar 11 is similarly operated by a press-plate mounted on the side-frame 1. Forward and rearward movement of the seat is permitted by a slot 54 therein through which passes the bar 11, forward movement being restrained by a one-way frictional damping device comprising a band wrapped around a rod secured to the bar 11 parallel thereto, the band being directly attached to the seat frame, directly at its forward end and by a spring at its rear end. Either bar 11, 12 may be lowered after depressing the corresponding finger plate 36, by the occupant permitting his weight to act on the seat against the force of springs 17, 20 connected to the slides 15, 16 and which can be allowed to raise the bars by the occupant relieving the seat of his weight. For assembling the seat and back to the side frames the rods 27 are held in the inner position in the bars 11, 12 by engagement of a catch plate 61 with a groove 62 in the rod. The end of the bar near the cross-pin 29 is then passed through the member 15 which is slotted at 63 to take the cross-pin in the vertical position.

Title: Improvements relating to the shedding mechanism of circular looms
IPC: D03D37/00
Filed: 1935-04-17
Abstract: 453,714. Circular - loom shedding - mechanism. BRITISH CELANESE, Ltd., 22, Hanover Square, London, HALE, F. C., c/o British Celanese, Ltd., Spondon, near Derby, and JABOULEY, J., 6, Rue SprÚafico, Villeurbanne, Rh¶ne, France. April 17, 1935, No. 11845. [Class 142 (ii)] The warp threads 20 pass through the eyes 44 of the dents in two or more reeds 40, 41 supported by a spider 42 at differing distances from the plane in which the shuttles move, pressing devices such as shedding wheels 45, 49, 50 penetrating from outside or inside the warp circle forming sheds for successive shuttles 24, 25, 26. The eyes in the dents of respective reeds may be arranged at different distances from the loom axis so as to form a shed apart from the action of the shedding wheels. In weaving 2 and 1 twill, of each three successive warp threads one a passes through an eye in a dent in the reed 40, a second b passes through an eye in a dent in the reed 41, whilst a third c passes through spaces between the reed dents. Three shuttles or a multiple thereof are used. A shedding wheel 45, which is mounted just in advance of the shuttle 24 on a bracket 46 on a ring 47 supported from the rotating ring 30 carrying vane wheel devices for driving the shuttles, acts on the warp threads to form a shed wherein the threads a are separated from the threads b, c. Just in advance of the shuttle 25, a shedding wheel 49 acts as shown in Fig. 3 to separate the threads b from the threads a, c this shed being formed somewhat to the right of the one previously mentioned and the nose of the shuttle 25 being accordingly inclined inwardly as shown so that the shuttle may readily enter the shed. Just in advance of the third shuttle 26, the threads c are separated from the threads a, b by the action of a shedding wheel 50 on an arm 51 on a freely rotatable spider 52 carrying a roller 54, so that it may be driven by the wheel 45. The weaving of a five shaft satin by means of five reeds each having eyed dents to receive one of each five successive warp threads is described. Shedding wheels with smoothly rounded edges of substantial depth and fabric covered as described in Specification 413,379 may be used. The invention may also be used in a loom wherein the shuttles are stationary and the warp rotates, or wherein both rotate.

Title: Improvements in and relating to the construction of hooped pipe-lines, reservoirs and the like
IPC: B21C37/15
Filed: 1950-05-12
Abstract: 676,569. Making pressure vessels and pipes. FERRAND, G. A. May 12, 1950 [July 26, 1949], No. 11935/50. Classes 83 (ii) and 83 (iv). In a method of making hooped pipes and other vessels for withstanding high internal pressure, wherein the wall of the vessel has been subjected to a permanent deformation in the cold, the hoops are also subjected to a permanent deformation by continuing the expansion of the vessel beyond the point at which the hoops are only elastically strained. A pipe 1 has a number of hoops 2 of larger diameter spaced along it and is then expanded by internal pressure so that the wall of the vessel is stretched beyond its elastic limit, first engaging. the hoops and then stretching them beyond their elastic limit. The final diameter of the pipe is determined by two. part rings 3 which are then removed. An existing hooped pipe having its hoops under elastic tension may be further expanded so as to permanently deform the hoops. A pipe of chromium-copper steel 0.71 inches thick with an internal diameter of 4 feet 11.05 inches has spaced along it at intervals of 3.04 inches, hoops of chromium-nickel steel 1 inch thick, 3.04 inches wide and with an internal diameter of 5 feet 3.236 inches. The pipe is subjected to an internal pressure of 4300 pounds per square inch, resulting in the pipe expanding about 7 per cent and the hoops about 2 per cent. Specifications 292,580, [Class 83 (ii)], 340,148 and 671,609 are referred to.
Patent GB-1104772-A (GB)
Title: Transformer cores and method of making same
IPC: H01F41/02
Filed: 1966-03-18
Abstract: 1,104,772. Making transformer cores, bending, shearing. TELCON-MAGNETIC CORES Ltd. 18 March, 1966 [30 March, 1965], No. 12025/66. Headings B3A, B3E and B3W. [Also in Division H1] A method of making transformer cores comprises cutting lengths of magnetic material from a strip thereof, the lengths all differing from each other, selecting a group of the longest of the lengths and assembling them into a closed ring with abutting ends, similarly arranging a group of the longest remaining lengths and assembling them within the first group and repeating these operations until all the cut lengths have been so assembled. A strip of grain oriented magnetic material 1 is advanced by a roller 3 through a shear device 8 until the end 9 of the strip contacts a switch 10 on an adjustable stop 11. Closure of the switch 11 cuts out the drive motor 4, actuates the shear device 8 and after a suitable time lag starts a motor 14 to rotate an indexing screw 15. The motor 14 also rotates a cam disc 18 via a variable speed gear 16. As the cut length of strip falls from the shear device, the switch 10 is opened, but the motor 14 remains energized via a switch 20, which is closed by a cam follower 21 acting on the disc 18 so that when the follower falls into a notch 22 the switch 20 is opened. The apparatus produces groups of laminations wherein the increment of length increase of each is equal or, if required, one or more laminations in a group may have a greater increment of length increase. A counter 24 is set so that after a pre-determined number of laminations have been cut, a magnetic device 25 retracts the stop 11 additionally to the movement caused by the screw 15. The apparatus may be arranged to cut the longest lamination first. A group of laminations is arranged with their ends in different transverse planes and a core group is formed between walls (45), (Fig. 5, not shown). The ends of the outermost lamination overlap, and they may be welded or taped together. Other core groups may be formed and placed in succession inside the first group and the air gaps between the butt jointed laminations may be arranged in zig-zag formation (Fig. 2, not shown). The core, with a mandrel 47 inside, is placed between forming plates 48, 49, 51 and an hydraulically operated piston forms the core to its final shape prior to heat treatment. Finally, if the outer laminations have been welded, the weld is broken, or if they were taped, the tape is burned up in the furnace during heat treatment.

Title: Improvements in or relating to control arrangements for electrically-driven doors
IPC: B66B13/14
Filed: 1960-04-05
Abstract: 899,757. Control of A.C. motors.- INVENTIO A.G. April 5, 1960 [April 10, 1959], No. 12036/60. Class 38 (3). A lift-door, which is driven by a squirrel-cage motor 1, is closed when change-over contact 2 is moved to energize contactor 3, the stator winding 1.1 being connected directly to threephase mains R, S, T. As the door approaches its end-position, a cam closes contact 11 to energize contactor 5 for introducing resistors 7 into the stator circuit. At the same time, contactor 6 6 is energized for D.C. excitation of brake winding 1.2. Contact 9 is opened in the end-position of the door to disconnect the brake winding, the contactors 3, 5 remaining energized,  however, so that the door is pressed against an end-stop. The door is opened shifting the contact 2 to release contactors 3, 5, and energize contactor 4, the motor exerting its full reverse torque. The speed of the door is reduced as the other end-position is approached by the closure of contact 12 for re-introdueing the stator resistance and re-connecting the brake winding. The motor is switched-off completely when it reaches its open-end-position. The brake winding is accommodated in the same slots as the main stator winding and has a pole-number which is greater or smaller by an even multiple than that of the three-phase winding.

Title: Improvements in or relating to cellulose acetate articles
IPC: D06M11/38
Filed: 1954-04-26
Abstract: Cellulose acetate filaments, threads, fibres, artificial horse hairs, films and like articles having an acetyl value of 45 to 52 per cent calculated as acetic acid, the distribution of the acetyl groups throughout the molecules being homogeneous, are obtained by extruding a solution of cellulose acetate having an acetyl value greater than 58 per cent into a coagulating bath and submitting the so formed articles, after substantially freeing them from solvent but before drying, to the action of a mineral alkali or of ammonia or an amine in a liquid medium substantially free from swelling agents or solvents for the acetate.  In a modification the articles, prior to saponification, may be submitted to at least one drying, but in this case a weak base, e.g. an amine or ammonia, must be employed for saponification.  The articles are characterized in that, after dyeing with substantive or plastosoluble dyes, they show a homogeneous dyeing throughout their cross-section and that they swell by at least 55 per cent of their volume on immersion in distilled water at 20-25 DEG  C. for 15 hours.

Title: An improved thrust bearing for eccentric thrusts such as in swash-plate axial-plunger pumps or engines
Inventor: TOWLER JOHN MAURICE
IPC: F16H23/00
Filed: 1946-06-17
Abstract: 676,614. Liquid-pressure engines. ELECTRAULIC PRESSES, Ltd. March 21, 1947 [June 17, 1946 ; July 3, 1946], Nos. 12098/47 and 12099/47. Divided out of 676,612. Class 69 (ii) [Also in Groups XXVIII and XXXIV] A thrust bearing assembly to support an eccentrically applied axial load, such as arises with a swash plate pump or engine having a plurality of plungers reciprocating in bores formed in a cylinder block and disposed around the axis thereof, comprises a shaft mounted so that it has a limited freedom to tilt and provided at its forward end with an enlarged head the forward face of which head co-operates with a surface of an intermediate member able to tilt slightly relative to the head and receiving on its other surface the eccentrically applied axial thrust, the eccentric thrust thus transmitted to the head being taken up on a fixed thrust ring with which the rear face of the tiltable head co-operates, these tilting facilities providing for a wedge-shaped oil film between the cooperating faces and surfaces so long as oil is continuously supplied thereto whereby the eccentric load is supported without any metal to metal contact arising. In the arrangement shown a driving shaft 1 has an enlarged head or swash member 2 with an inclined face 3 engaging a wobble plate 4. The rear face of the swash member 2 engages a hardened steel thrust ring 7 seating against the outer race 8 of a ball or roller journal bearing. The shaft 1 is driven from the main shaft through a flexible coupling 9 and being mounted only in a single journal bearing it follows that the swash member 2 can tilt relatively to both the wobble plate 4 and the thrust ring 7 so forming wedge spaces A, B. One of the opposed surfaces may be faced with soft metal or a washer with a soft bearing-metal face may be pinned on the swash member. Radial holes 11 are formed in the wobble plate 4 and in the thrust ring 7 to supply oil to the inner ends of radial grooves in the faces of the swash member 2 along which the oil is then propelled by centrifugal action. To maintain the operative surfaces plane when under pressure and so prevent breakdown of the oil film the surfaces are made slightly concave and flex under the pressure. Alternatively the thrust ring 7 may be supported by an annulus of smaller width (outer race ring 8) lying within its diameters. Specification 676,612 is referred to.
