Title: Improvements in joints between relatively rotatable conduits
IPC: F16L39/04
Filed: 1944-11-29
Abstract: 625,411. Pipe joints. BARCLAY, CURLE & CO., Ltd., and McNEE, J. B. Nov. 29, 1944, No. 23817. [Class 99(i)] A rotary pipe joint comprises a gland ring 30, Fig. 5, screwing into a socket 29, and bearing on a floating ring 37 which is mounted on a rubber sealing ring 38 on the pipe 27 so as to rotate therewith, but having limited freedom for axial and lateral movement. The ring 37 is pressed against the gland ring by a spring 44 which extends between a shoulder on a sleeve 39 secured to the pipe 27 and an intermediate ring 41 which bears on the sealing ring 38 and through rounded projections 45 on the floating ring. The intermediate ring has claw-and-recess connections 42, 43 with the sleeve and floating ring. The joint forms part of a hinged connection for two pairs of pipes. The pipes 20, 21, Fig. 4, are secured in a member 28 and each communicate with a hollow trunnion 29 mounted in a ball-bearing 31. The casings 33 of the bearings are integral with a double elbow fitting 26 in which is secured the other pair of pipes 18, 19. The fitting communicates by elbows 25 with the spigots 27 which fit in the hollow trunnions, and communicate with the pipes 20, 21.

Title: Manufacture of wood fiberboard
IPC: D21J1/00
Filed: 1962-06-21
Abstract: Wood fibreboard having a thickness of at least 1/4 inch and a density of 10 to 75 lb/ft3 is made by digesting hardwood chips under pressure up to 300 lb/in2 in caustic alkali solution at a temperature of 70 to 200 DEG F. for a time of 1/4 to 2 hours, separating the chips from the digestion liquor, refining the chips to a fibrous mass having a TAPPI drainage time of 10 to 60 seconds, forming an aqueous furnish of these fibres, applying this furnish to a foraminous support and partially deviating it to form a web, and drying the web.  An insulating board of density 10 to 35 lb/ft3 is obtained without hot-pressing, or a hardboard of 35 to 75 lb/ft3 by accomplishing at least part of the drying in a hot press.  The black liquor from the digestion step can be fortified with 50% caustic soda solution and reused.  The furnish may also include other fibres, e.g. of ground wood, may have its pH adjusted with sulphuric acid or alum and may contain a petroleum wax emulsion, or asphalt emulsion or pigments. Fibreboard according to the present invention can be united with a board of ground-wood fibres by pressing the two together.

Title: Improvements in carbon black and carbon black processes
IPC: C09C1/50
Filed: 1964-06-10
Abstract: Carbon black is produced by continually introducing a fluid hydrocarbon into a zone wherein an inert, elementary gas having no more than two atoms per molecule, at a pressure of at least one atmosphere, is subjected to a radio frequency, electrodeless discharge to maintain the gas in a thermal plasma state. Suitable fluid hydrocarbons are methane, ethane, ethylene, butane, butylene, and higher homologues of saturated and unsaturated hydrocarbons and fuels containing same.  The gas may be helium, neon, zenon, radon, argon, nitrogen, hydrogen.  In the Figure, argon is fed tangentially under positive pressure into annular space between quartz tubes 12 and 11 so that it spirals up through tube 11 and remains in close proximity to the inner walls.  Radio frequency current, e.g. 3 to 5 megacycles for monatoric gases from a generator is supplied to cylindrical copper coil 24 which may be hollow to circulate coolant therethrough.  Metal tube 14, connected in air-tight fashion with hydrocarbon <PICT:1068519/C1/1> feed line 16, is raised into reaction zone 10 wherein it is heated by the high-frequency field and creates a localized plasma which establishes a thermal plasma.  Tube 14 is then lowered. Alternatively, the plasma may be started by a tantalum, or other metal, wire or a carbon rod, and withdrawn after initiation. Fluid hydrocarbon is fed through tube 14 at say 39 mm./sec. into the plasma zone, wherein the temperature is at least 8000 DEG  K. The carbon black may be collected by directing exhaust gases and produce carbon through a collection system, e.g. pyrex cyclones and bag filter, by an exhaust fan.  The carbon blacks are characterized by small particle sizes, with a small, average number of crystallites per particle, and are useful as pigments or fillers.

Abstract: 1,197,834. Alkali metal borosilicate, hollow or multicellular glass particles. EMERSON & CUMING Inc. 21 May, 1968 [2 Aug., 1967], No. 24052/68. Heading C1A and C1M. Hollow multicellular spherical particles of alkali metal borosilicate having discontinuous skins and a preferred density of 0À1 to 0À4 g./cc. are prepared by spraying a homogeneous sol of an alkali metal borosilicate into a drying chamber into which is introduced a gas at at least 200 F. preferably 500-700 F. The sol is preferably sodium borosilicate having a water content of between 70 to 95% and the gas is preferably air. Hollow glass spheres may be produced from the above spherical particles by passing gas upwardly through a furnace which is at a temperature sufficient to fuse the particles, introducing the particles in the lower part of the furnace with a blowing agent, the particles being borne through the furnace by the gas at a velocity to permit transformation by fusion into unicellular hollow glass spheres.

Title: Improvements in and relating to electric control systems
IPC: G05F1/32
Filed: 1938-08-16
Abstract: 513,978. Control systems for consumption apparatus. THORNTON, A. A. (Vickers, H. F.). Aug. 16, 1938, No. 24125. [Class 38 (iv)] A system adapted more particularly for the control of lamp circuits to secure graduated control of lighting effects, as in stage lighting, comprises a saturable choke 3 with two outer limbs carrying windings 4, 4a respectively which at one end are together connected to one side of an A.C. supply 1 and at their other ends are respectively connected through two oppositely directed asymmetrical conducting-devices or valves 5, 5a to one side of a load circuit 2, the other side of this circuit being connected to the other side of the AC supply 1. A control winding 8 upon the central limb of the choke is adapted to receive a variable and reversible direct current by connecting one end to the mid-point 10a, of a potentiometer 10 which is connected across a battery 9, whilst the other end of winding 8 is connected to a movable contact 10b adapted to be moved to any point on either side of the connection 10a. The windings 4, 4a are such that the intermittent currents therethrough produce fluxes in the directions indicated by the arrows in the outer limbs of the core, while the direction of -the adjustable current around the central limb can be altered so that it increases or decreases the flux therethrough due to the windings 4, 4a. In this manner the alternating current through the lamps 2 can be varied progressively to obtain dim or bright illumination. Impedance devices such as non-inductive resistances 7, 7a may be shunted across the rectifiers 5, 5a respectively, and serve to protect the rectifiers from the effects of high reverse voltage, and also pass a small reverse exciting current through the load windings 4, 4a during their inactive periods. thereby co-operating with the reverse control current to reduce the voltage applied to the load. In a modification the load windings 4, 4a, Fig. 3 (not shown), are reversely wound and pass flux alternately in opposite directions through a central control limb carrying a winding the ends of which are connected across an adjustable inductor, whereby the currents induced in the control winding can be regulated and correspondingly vary the reactances of the load windings 4, 4a to control the lighting circuit. In a further modification of the arrangement shown the reactor core is divided into two closed rectangular cores which share the control winding arranged in two parts connected in series in the same direction.
