Title: Welding method including backgrinding
IPC: B23K33/00
Filed: 1973-04-26
Abstract: 1474181 Welding by fusion and grinding REDPATH DORMAN LONG Ltd 26 April 1974 [26 April 1973] 19957/73 Headings B3R and B3D In a method of joining two metal plate edges by welding at least one edge to be joined is chamfered, as at 51 in Fig. 11, to leave a root face 11, Figs. 2 and 9, on that edge. The root face is abutted with a flat surface on the adjacent edge of the other plate forming a V groove on one side of the abutting surfaces. The groove is then welded at 53, Fig. 11, and metal is then removed from the other side of the abutting surfaces until the surfaces are completely removed, e.g. as shown at 16 in Fig. 5, to expose the inner portion of the weld metal. Finally, further weld material 13a, Fig. 6, is deposited in place of the removed metal. In at least the final stages of the metal removal step the metal is ground out by a high speed grinding wheel 15, Fig. 9, arranged to exert a substantially constant pressure on the metal to be removed, having a substantially constant speed of advance and having its axis maintained in a direction perpendicular to the direction of the weld. The weld metal may be initially removed by back-gouging e.g. arc-air gouging or flame gouging. In addition to forming chamfer 51, in Fig. 11, a chamber 54 may be formed on the other edge. Further chamfers 55 and/or 56 may be formed on the rear side of the plate edges to form a 'V'-groove 52 on the rear side which may have an angle of 90 degrees, while the first groove may be 60 degrees. The included angle of the edge of the grinding wheel is chosen to be less than that of groove 52 e.g. 40-70 degrees and preferably 60 degrees. The wheel may be resinoid having a root radius of 3/16 inches and capable of speeds of 9,500 surface feet per minute. A suitable apparatus for carrying out the grinding step on circumferential welds of drilling rig tubulars is shown in Fig. 7, wheel 15 is rotatably supported on an arm 16a pivotally supported between blocks 18 of supporting structure 19, 20 by means of a linear bearing which allows axial float. The wheel is counterbalanced by driving motor 17 and is urged into contact with the weld by the operator by means of handles 21. In the modification of Fig. 8 the wheel is urged upwardly by a pneumatic cylinder 22 under the control of the operator by means of valve 27. A hydraulic damper 31 is also provided. For grinding longitudinal welds on tubulars, the apparatus shown in Fig. 10 may be used. A column-supported boom 33 carries a bracket 39 pivotally supporting an arm 35 which carries a motor for driving via a chain drive, the wheel 37 which is supported with casing 38 on an arm 39 pivoted to arm 35. The depth of the wheel is controlled by adjuster 40 on pivoted L-shaped arm 41 carrying depth control wheel 42. Other conventional adjustments include tilt and position of the grinding wheel and means to reform the grinding edge-of the wheel.

Abstract: 1,001,130. Voltage measurement. KOZPONTI FIEZRIKAI KUTATO INTERGET. May 20, 1963 [May 18, 1962], No. 20026/63. Heading G1U. [Also in Divisions H3 and H4] Apparatus converting the direct current in an atomic radiation detector to a corresponding pulse frequency for integration and indication comprises an electronic valve with grid connected to the detector and over a capacitor to the anode which is resistor connected to positive of a first D.C. source; to a second D.C. source over a semiconductor diode, and to the input of a regenerative voltage comparator whose positive level lies intermediately the D.C. source potentials; the cathode of the valve being connected to a third D.C. source and a discharge circuit being provided between the grid of the valve and the common negative of the D.C. sources while the pulse frequency appears at the output of the comparator, resultant to a successive integration and discharge in the valve circuit. A detector D for nuclear radiation is connected to the grid of a triode 10 having capacitor 13 connected between grid and anode; the latter being energized from first D.C. source 15 over resistor 14 and connected to the cathode of semi-conductor diode 16 returned to a second D.C. source 17 more negative than the first source. The anode is connected to the input of a regenerative voltage comparator comprising a transistorized monostable blocking oscillator 20,21 incorporating two coupled iron cored oscillator coils 22, 23 the comparison level lying between the two D.C. voltages. The triode cathode is returned to a third D.C. source whose voltage lies between that of the common negative of sources 15,17 and that of the anode of diode 16, and a winding 27 coupled to 22, 23 is returned to the common negative of 15,17 and connected to the grid of triode 10 through the anodecathode circuit of hard diode 28 in a discharge circuit. The current from the detector charges capacitor 13 to drive the anode of triode 10 positive to exceed the emitter voltage of transistor 20, when a negative voltage arises across resistor 14 to operate the blocking oscillator. A positive pulse excited in coil 27 drives triode 10 conductive to discharge the capacitor 13 to a critical voltage, after which integration recommences. The comparison levels are determined by the opening of the base-emitter circuit of transistor 20 and of the semi-conductor diode 16 and a pulse sequence proportional in frequency to the detector current is derived at 31 from coil 23 for integration to operate a detector current inductor. A logarithmic D.C. amplifier may be introduced into the integrator circuit, and the output may also be applied to control circuits.

Title: Manufacture of artificial threads and other products from cellulose compounds
IPC: D06M11/38
Filed: 1932-07-15
Abstract: Artificial threads and other materials made from compounds of cellulosic xanthates with halogen containing organic compounds, or from xanthates of cellulose derivatives, are treated with alkali sulphide first at a temperature not greater than 25 DEG  C. and then at a temperature above 40 DEG  C.  The cellulosic xanthate may be cellulose xanthate, or a xanthate of an alkyl or hydroxy-alkyl ether of cellulose, or a mixture of these substances.  If desired a single solution may be employed for the two stages of the treatment, the bath being heated at the conclusion of the cold treatment. Alternatively two baths of the same or different concentration are used.  In an example, a dry or wet skein of artificial silk of the kind specified is immersed, sprayed, or otherwise treated with 30 per cent sodium sulphide solution for 10--20 minutes at room temperature. The solution is then quickly heated to 100 DEG  C. and the skein kept therein for 10--20 minutes. The skein is removed, washed with hot and cold water, acidified, again washed, and dried.  In other examples: stronger solutions up to 58 per cent or weaker solutions down to 10 per cent of sodium sulphide are employed; separate cold and hot baths are used instead of a single bath; the second stage of the treatment is carried out at 60 DEG  C.  Specifications 335,906, 335,993, [both in Class 2 (ii)], 341,899, 341,930, 357,527, 357,595, 368,288, 385,979, 390,518, and 390,519 are referred to.

Abstract: 499,378. Kinematograph apparatus. DAMBLANC, L. July 20, 1937, No. 20104. Convention date, July 20, 1936. [Classes 97 (i) and 98 (ii)] In apparatus in which a continuously moved picture film or band is directly viewed the shutter is driven by frictional contact with the picture band and comprises an opaque band having transverse slots. The picture band may be of paper on one or both sides of which the pictures are printed, e.g. by heliogravure in their chronological order. As shown the picture band 1 is fed from a spool 6, one end of which engages a bearing 8 in a removable cover 7 and is taken up on a spool 3. A transversely-slotted continuous band shutter 17 engages the film over a part a of the spool 3 and is continuously driven thereby, the tension being maintained by a spring-pressed roller 20. Observation may be effected through a funnel 26 and a lens 33, a lamp 32 illuminating the band 1. A masking diaphragm 24 which may be adjustable in size, is vertically movable on guides 31 by a pinion 27 on a rotatable shaft engaging a rack 29, Fig. 2. Winding and rewinding of the band 1 are effected through a wheel 9 which is free on the shaft 5, and may be axially moved, either to engage teeth 10 to drive the spool 3 by a crossed belt 12, or to engage teeth 14 to drive the shaft 5 and rewind the band. The wheel 9 may be rotated manually by a handle 15 or driven by an electric motor 16. To exhibit the images on the other side of the band 1, the band is rewound on the spool 6 by driving the spool in the direction which is the reverse of that for normal rewinding ; the spool 5 is then removed and reinserted in the reversed position before threading. Two picture bands may be used for stereoscopic observation. According to the Specification as open to inspection under Sect. 91 the picture band may be of the type described in Belgian Specification 412,666, the shutter may be driven by engagement of fingers on a drum driven by the picture band with perforations to the shutter, and a projected image may be viewed on a ground glass screen in the casing. This subject-matter does not appear in the Specification as accepted.

Drawings to Specification. [Class 40 (iv)] In a signal transmission system of the double pulse modulation type, that is one in which the momentary amplitude of the original signal is represented in the line by the position of a short signal impulse (which may be a direct current impulse or a burst of high frequency alternating current) in a time period the end of which is fixed by one of a stream of regularly recurring impulses of a similar kind which may or may not be transmitted, the same repeaters are used 'for both directions and are automatically brought into condition for repeating in the appropriate direction by the signals themselves. The repeaters are identical with some of those described in Specification 509,820 and are of the kind in which a multivibrator circuit normally sends direct current impulses to line or in which a high frequency oscillator coupled to the line is periodically quenched and the effect of received impulses is to alter the starting point of the multi-vibrator or quenching cycle. It is shown, since signals arriving in appropriate phase with respect to the impulses generated by a repeater drag the repeater into step with them, that if such repeaters are suitably spaced and if speech at the terminal station always causes an advance of the phase of impulses generated there, the whole system is brought automatically into condition for relaying in the direction of the speech and remains in that condition until speech is originated at the other end whereupon the direc- 'tion of relaying is reversed.
