Title: Improvements in dry gas meters
IPC: G01F3/22
Filed: 1954-07-30
Abstract: 739,587. Gas meters. FASNACHT, R., GISLER, E., and ANGST, E. July 30, 1954 [Nov. 9, 1953], No. 22250/54. Class 54. A dry gas meter has two measuring chambers and a movable diaphragm therebetween, and means to operate a slide valve 9 comprising a shaft 19 which engages the valve through an arm 21 and a flexible rod 22 and is oscillated by an arm 25 connected to a flag rod 32 by a spring 34. This spring engages a notch 27 in one end of the arm 25 and a bracket 33 secured to the flag rod 32 so that as the bracket is swung to and fro by the movement of the diaphragm the spring is tensioned until it can cause a rapid movement of the arm 25 and, through the shaft 19, the valve 21. Angular movement of the arm 25 is limited by a pair of stops 29, 29<SP>1</SP> of rubber or other sound damping material which co-operate with a pair of projections 26, 261 on the arm 25. One or both of these projections may be provided with a screw 28 to permit the angular movement to be adjusted. An arm 36 and a rod 35 also operated by the flag rod 32 actuate a counting mechanism. Gas enters and leaves the measuring chambers by way of ducts 6, 7 which are alternately connected by the valve 9 to a chamber 10 fed by the inlet pipe 12 and a duct 14 leading to a chamber 4 communicating with the outlet pipe 17. The flexible rod 22 engages slits in the walls of the valve 9 and causes increased pressure to be applied to the latter at the ends of its stroke.

In a tank, Fig. 2B (not shown), for storing liquefied gas having an outer supporting concrete shell 13, 14 provided with a lining of insulation 25, a lining of sheet material 32 impervious to liquid or vapour is disposed between the insulation 25 and a layer of non- rigid material 29, and the insulation 25, the sheet 32 and the material 29 are held in place by outwardly urged shoes 37 which abut the material 29. The insulation 25 is composed of a plurality of blocks 26 arranged in layers 27, 28 with the joints 31 between the blocks in adjacent layers being staggered. The blocks 26 and the layer of material 29 are preferably made of a cellular expanded plastic, e.g. urethane. The shoes 37, Fig. 4 (not shown), are supported by a plurality of vertically extending members 38 and are urged outwardly against the material 29 by compression springs 39 disposed between abutments 41 located at the ends of adjacent shoes. A modified method of supporting and outwardly urging the shoes 37 is described with reference to Fig. 5 (not shown). To allow for expansion and contraction, the concrete wall 14 of the outer shell is separated from the concrete floor 13 by a plate 16, a layer of " Teflon 21 " (Trade Mark) and a sheet-metal shield 22. The concrete wall and floor may be integral and the wall 14 is preferably prestressed with a wrapping of wire 23. In order to prevent the formation of frost and ice below the tank, gas to be liquefied is passed through conduits 12, Fig. 1 (not shown), disposed below the tank before being liquefied by equipment 56 and injected into the tank through a conduit 57. A pump 59 is provided for withdrawing liquefied gas from the tank. A series of narrow grooves 51, 49 are provided respectively in the wall 14 and the floor 13 to collect vapour which permeates through the sheet 32. The roof insulation 25 is supported by hangers, Fig. 2A (not shown), secured to the roof 15, and the space 33 therebetween may be purged of vapour by introducing purge gas through inlets 54 and withdrawing gas through an outlet 55.

The groove may be in the form of a continuous or broken helix.  As shown in Fig. 1, a filament 1, formed by extrusion of organic plastic material through an orifice, is provided with grooves 2, 3, set at an angle to the longitudinal axis of the filament, and extending round the filament in helical fashion. If desired, the grooves may be at right angles to the axis.  As shown, there are two series of grooves formed on opposite sides of the filament.  They may be formed by passing the filament between a pair of shaping rollers while it is in a soft state, e.g. immediately after its extrusion. The filament may be formed by extruding a hot cellulose ester composition and solidfying by cooling, or it may be formed by extruding viscose into an acid coagulating bath.  Fig. 7 shows a filament with helical grooves formed similarly to those of Fig. 1 except that the grooves are narrower and not so deep.  In Fig. 3, the helical grooves 6 extend continuously round the filament. They may be formed by providing in conjunction with the extrusion orifice a shaping orifice which is rotated continuously during the extrusion at constant speed.  As shown in Fig. 5, the filament is provided with two sets of grooves, one set passing in unbroken helix fashion round the filament, and the other set extending longitudinally or at a different angle from the first set.  The grooves 8 may be formed by a rotating die, and the grooves 9 may be formed by a die which is stationary or which rotates in the opposite direction or at a different speed from that of the other die.  The filament of Figs. 9 and 10 has two deep helical grooves 15, 16, which extend from end to end.

Title: Process for cracking hydrocarbons
IPC: C10G9/36
Filed: 1961-06-21
Abstract: In the pyrolysis of hydrocarbons by contact with a hot carrier gas to form acetylene and ethylene, the reactants are surrounded by a veil of steam flowing along the walls of the reaction chamber at a velocity at least equal to that of the reactants and in the same direction. The steam may be introduced into the chamber where the hydrocarbon is mixed with the hot gas or more usually at the beginning of the reaction chamber.  The velocity may be 1-1.5 times that of the reactants, suitably in the range 100-500 m./sec.  At the point of entry the steam may be 1-15 mm. in width and at a temperature of 200-1,000 DEG  C. and may be preheated by heat exchange with the reactor walls before entering.  The reactor walls should have a temperature of 700-900 DEG  C. The reactor may have parallel walls or be conical in shape, the angle of aperture being 10-30 degrees.  Where the reactor is long, further steam may be added to maintain the veil at points along the reactor walls.

Each shoe is urged into frictional engagement with the rim of the pulley 19 by a compression spring 30 acting against the bearing 27 and a collar 31 secured to the bar 24. A rod 11 slidable in the shaft 8 is movable outwardly by a lever 13, and a nut 39, adjustable on the rod and locked in position by a nut 40, acts on bellcranks 34 to move the shoes out of engagement with the pulley rim against the action of the springs. Angular displacement of the shoes is prevented by offset extensions 28 of the bearings 26, bifurcated to engage parts 29 of reinforcing web portions 25 of the shoes. For removal or application of the clutch mechanism, the shoes can be held disengaged by means of a straight metal locking rod having ends bent over to enter holes 43 in lugs 42 projecting from the web portions 25.
