Title: Explosively assembled pipe coupling
IPC: F16B7/04
Filed: 1972-09-05
Abstract: 1346704 Welding by pressure AMP Inc 5 Sept 1972 [27 Sept 1971] 41051/72 Heading B3R [Also in Divisions F2 and H2] In a method for connecting two pipes 2, 4 annular wedges 16, 18 are located around the ends 10, 12 of a tubular member 8 and, when located within the pipe ends, the wedges are driven towards each other by an explosives operated tool, thereby joining the pipes to the tubular member. The wedges each comprise a series of axially extending wedge segments 30 separated by flutes and grooves (22) (Fig. 2, not shown) but connected by frangible lateral webs (28). As shown, the pipe ends abut a collar 14 around the tubular member 8. As the wedges are driven towards each other they break into individual segments 30 and, when metal components are used, cold welding occurs between the wedge segment surfaces, the inside bores of the pipes 2, 4 and the tubular member 8. The joining tool, which is located through the member 8 and wedges 16, 18 before insertion in the pipe ends, comprises a chamber wherein a piston is driven along a cylinder by the force of an explosives charge 50. The end of the chamber and an end cap 62 screwed on a piston-rod 56 are arranged to abut the ends of the wedges 18, 16 so that the explosion will drive them towards the collar 14. The piston 56 is then unscrewed from the cap 62 which may be left in place or removed. Since the joint is cold-welded the pipes are also connected electrically and they may function as conductors or as fluid carrying conduits.

Abstract: 1,165,227. Digital measurement of area. CUSTOM CONTROL PRODUCTS Inc. 11 Sept., 1967 [15 Sept., 1966; 19 June, 1967], No. 41357/67. Heading G4H. [Also in Division G2] An optical scanner for measuring the area of an object, e.g. a hide, comprises a source of light 39, Fig. 4, below the hide, and a series of light guides 14 co-operating with apertures 38 in roller 33 above the hide, the light guides passing to a scanner where they are presented each in turn to a photo-cell, the photo-cell also receiving light pulses out of phase with those from guides 14 so that so long as light is received over the light guides, no output is obtained from the photo-cell, but where the hide prevents light reaching a light guide, a pulse is given. The hide passes between apertured roller 33 and a transparent roller 34 surrounding the lamp 34. Roller 33 is driven by a motor 42 through a pulley belt 51. The light guides 14 are taken in a bundle 16 to the scanner 10 where the ends 12, Fig. 2, are arranged in a circle on plate 17 and scanned by a light guide 19 rotating with wheel 18 taking light from each guide in turn to photocell 24. Another light guide 29 co-operates with spokes 32 of the wheel to apply light pulses to photo-cell 24 between those from guides 14. If there are 30 rows of apertures 38 in the cylinder the wheel 18 rotates 30 times for each rotation of drum 33. The apertures are arranged in a staggered pattern in each row and they are scanned in a random order to prevent errors occurring at the margins of the hide. While each aperture in the drum is unobstructed the photocell receives constant light, pulses from guide 19 alternating with pulses from guide 29. If a hide is present certain light guides are blocked and corresponding pulses appear from photo-cell 24 to be counted in counter 26. Each pulse represents a unit of area of the hide passing through the apparatus.

[Also in Divisions C7 and H1] An electro-photographic plate comprising a supported softenable layer (e.g. of resin) having therein or thereon a disruptable layer, has an electrostatic charge image formed thereon and is softened by heat or solvent so that the fracturable material migrates and adheres to the support. Alternatively the softenable layer is imagewise treated (e.g. with uv light) to prevent migration in the treated areas, uniformly charged, and softened. The disruptable layer may be photoconductive and a charge image formed by uniform charging (e.g. using a corona discharge, or a brass plate coated with silicone oil to which a voltage is applied) and imagewise exposure. An electrostatic image may be formed on a non- photo-conductive disruptable layer by imagewise exposure to a corona discharge or electron beam using a mask or shaped electrode, or by charge transfer from a photo-conductive layer. Image contrast may be increased by removing the softenable layer and non-migrated material by abrasion or solvent.

Abstract: 918,878. Photo-electric high-resolution spectroscopy. IMPERIAL CHEMICAL INDUSTRIES OF AUSTRALIA & NEW ZEALAND Ltd. Dec. 19, 1960, No. 43656/60. Class 40 (3). A range of wavelengths in a beam of light, ultra-violet or infra-red radiation is scanned by passing the beam into an absorbing medium and applying either the Zeeman or Stark effect to the source of the beam or the absorbing medium. An emission spectral line in the light beam 10, Fig. 1, is investigated by putting a gas in the chamber 12 which has an absorption line near the emission line, splitting the absorption line with the Zeeman effect provided by the coils 20, removing one split component with a nicol prism 14 and a quarter-wave plate 15, varying the current in coils 20 to scan the remaining component relative to the emission line and recording the variation of output of a photomultiplier 17 on XY recorder or oscilloscope 19. In Fig. 2 (not shown), the resonant radiation is measured to indicate the absorption. Measurement of partial pressures.-Light from a lamp 40, Fig. 5, excites resonance in a chamber 43 to an extent dependent upon the concentration of the scattering atoms and this is detected by a photo-cell 45, compared with the output of a correction photo-cell 47 and recorded. To eliminate variations due to line shift and broadening the whole line is scanned and the output integrated. Measurement of temperature.-Source temperature is measured by scanning the emission line with a narrow absorption line to determine the Doppler broadening. The temperature of an absorber is determined by measuring the half-width of a line absorbed from a continuum, or by scanning the absorption line with a narrow emission line. Isotope analysis.-An isotope mixture in the source or absorber is investigated using a pure isotope in the absorber or source, respectively. The relative intensity of the emission or absorption lines due to the individual isotopes indicates the relative abundance. The isotopes investigated may be in the upper atmospherestrontium, lithium or sodium fluorescing under  excitation by the sun, auroral electrons or cosmic rays. Measurement of gas velocity.-Light frdm a source 51, Fig. 6, is passed in two different directions through a wind tunnel into which has been introduced atoms of an absorbing gas. The emission line is shifted by the Zeeman effect to scan the absorption lines on the two paths and the Doppler shift therebetween indicates the wind tunnel gas velocity. The velocity of gas in the upper atmosphere is measured by scanning the fluorescence therefrom with an absorption line and determining the Doppler shift and broadening of the line. Specification 918,879 is referred to.

Abstract: 1,236,604. Supply systems for gas discharge lamps. BERKEY PHOTO Inc. 16 Sept., 1968 [9 Oct., 1967], No. 43915/68. Heading H2H. An electric system providing an A.C. supply to a gas discharge lamp'has a saturable inductance, such as an autotransformer 14, in series with a capacitor 17 and the gas discharge lamp 24 which has a low impedance when initially ignited and increases in impedance as the lamp is warmed to operating temperature. The respective values of the impedances of the three components are such that a harmonic is generated in the series circuit upon ignition of the lamp to effect quick warming of the lamp and at operating temperature the circuit is close to resonance at the supply frequency to provide regulating action in the event of variations of supply frequency. The harmonic is preferably a third harmonic and the autotransformer is of the shell type with magnetic shunts (Fig. 2, not shown) between the windings on a central core and the outer limbs. Starting pulses from a transformer 20 pass through the lamp 24 and a low capacity capacitor 27.
