Abstract: 1345055 Separating hydrocarbons by adsorption UNION CARBIDE CORP 13 Sept 1971 [14 Sept 1970] 42517/71 Heading C5E Normal paraffins are separated from non- normal hydrocarbons by passing the mixture in the vapour phase through a fixed bed of zeolite molecular sieve adsorbent, e.g. calcium zeolite A, until 85-97% of the adsorption capacity of the bed has been utilized and thereafter isotherally and isobarically passing a countercurrent of non-sorbable purge gas through the bed firstly to remove hydrocarbon from the bed void spaces but not to remove more than 20% of the adsorbed normal hydrocarbons in the purge effluent and then desorbing at least a major portion of the normal paraffins from the bed with the purge gas. The process is carried out at 350-750 F. and can be used to separate mixtures of C 4  to C 14  hydrocarbons, such as boil in the gasoline or kerosine ranges. A system comprising 5 beds of adsorbent is illustrated in which each of the beds 34, 36, 38, 40 and 42 undergoes a cycle of (a) 2 minutes passing feed stock into the bed at a slow rate to remove residual purge gas, (b) 4 minutes passing the feedstock through the bed at the full feed rate, (c) 2 minutes first stage desorption with purge gas to remove hydrocarbon vapour from the bed void spaces but not to produce more than 20% of the adsorbed normals in the purge effluent, and (d) purge to desorb normal hydrocarbons from the bed. The adsorbent beds can be regenerated by purging with a countercurrent of nitrogen at 750 F. and 60-100 p.s.i.a. and then including up to 1% oxygen in the nitrogen, this amount of oxygen is controlled so that the maximum gas temperature does not exceed 1000 F. Suitable purge gases are nitrogen, hydrogen, helium and methane.

A process for improving the flatness of sheet glass comprises feeding a sheet of glass at a temperature measured such that the glass has a viscosity of from 10<SP>5</SP> to 10<SP>6.5</SP> poise to a pair of flattening rollers each having a smooth flattening surface and maintained at a uniform temperature of from 400‹ to 650‹ C. and being separated from each other by a distance of from 75% to 95% of the initial thickness of the glass sheet, rolling the sheet between the rollers and transporting the rolled sheets from the rollers. The two rollers 6a and 6b are supported by bearings 14 and 17 respectively carried by a frame 15, a pair of chocks 18 supporting the bearings 17, the chocks thus determining the separation between the rollers. A pair of hydraulic jacks 19 exert a force on the upper roller 6b through bars 21 and the bearings 17. The two rollers are maintained at a uniform temperature throughout their length by air cooling a central portion and electrically heating the end portions of each roller. Preferably the sum of the temperature of the glass and the temperature of the rollers should be between 1350‹ C. and 1400‹ C. The glass may be fed to the rollers 6a, 6b on rollers 5 or on a gas cushion. The glass may be removed from the rollers on a gas cushion or on a liquid metal bath. The process is said to produce glass having depressions in the surface of less than 0À1 mm. depth, of average depth 0.01 mm. and each depression having a surface area of from 1 to 30 sq. cm. A glass composition is disclosed having 71% SiO 2 , 0.1% Fe 2 O 3 , 11% CaO, 3.0% MgO, 14.0% Na 2 O + K 2 O, 0.3% SO 3 , 0À6% Al 2 O 3 . U.S.A. Specification 3,442,748 is referred to.

A telescopic hydraulic shock-absorber comprising a piston 14 which works in a cylinder 10 coaxially enclosed within an outer cylinder 12 to define an annular reservoir space 28 and a valve system which ensures a unidirectional flow of hydraulic fluid during operation is characterized in that the cylinders 10, 12 are closed and joined at one end by a rod guide 18 through which a piston rod 16 passes and at the other end by a plug member 22, the piston 14, the rod guide 18, and the plug member 34 being ported and the flow of fluid being controlled in each instance by an annular disc valve 50, 40 or 34 at least one of which is pre-tensioned to determine the damping characteristic of the shock-absorber. The disc valve 40 is loaded by a spring 42 and controls ports 38 in the piston 14, and the valve 34 is loaded by a spring 36 and controls ports 30, 32 in the plug member 22, the valve 50 being in the form of a diaphragm which is clamped between the rod guide member 18 and the cylinder 10 and which overlies an annular groove 48 formed in the member 18. The groove 48 communicates with three, or more, equiangularly-spaced grooves 46 formed in a spigot portion 44 of the member 18. An anti-foam sleeve 52 co-operates with the cylinder 10 to define an annular space 54 for the reservoir air or gas and is formed with an inclined shoulder 56 which is secured to the cylinder 10 and which co-operates with the guide member 18 and the cylinder 12 to form a chamber 58 for receiving the fluid discharged from the valve 50. Fluid flows from the chamber 58 to the reservoir 28 through a narrow annular passage 60 between the sleeve 52 and the cylinder 12. A port 53 in the sleeve 60 limits the level of fluid within the space 54. The diaphragm valve (50) is pretensioned by offsetting the outer margin (19) of the groove (48), which is provided with a shallow bleed notch (19a), Fig. 3 (not shown), the end (11) of the cylinder (10) which abuts the diaphragm (50) being radially inwardly-chamfered at a small angle.

[Class 99 (ii)] In a soot blower comprising a nozzle, not shown, mounted on the end of a blower tube a, Fig. 1, the tube a is connected to a sleeve e which is provided with ports f adapted to be brought into and out of coincidence with ports in a coaxial sleeve i which is fixed in the blower head j so that compressed air or steam controlled by a hand-actuated valve w in the head j is supplied to the nozzle in a succession of blasts upon rotation of the said sleeve e, rotation of the sleeve c through about 120‹ being effected by the compressed air acting on a piston p which is provided with a stem o in screw-threaded engagement with a spindle m projecting therefrom. The piston p is normally located at the left-hand end of a cylinder q which is mounted on the head j and is provided at its ends with connections 2, z leading from the inlet and outlet sides of the valve w respectively, and when the said valve is opened the pressure on the righthand side of the piston will overcome that on the left-hand side, due to the difference in effective area of the two sides of the piston, and move the piston to the right thus rotating the sleeve e, the piston being returned to its normal position when the valve w is closed and the air supply to the connection z is shut off. The rate of movement of the piston p may be controlled by a dash-pot device t, and an indicator v may be provided to indicate the angular position of the blower nozzle. In a modification the valve w is opened by hydraulic pressure acting on a spring-loaded piston 4 integral therewith through a connection 5, and where a number of blowers are installed they are preferably operated automatically in sequence by the device shown in Fig. 3. This device comprises low and high pressure spaces 14<a>, 16 respectively, constituted by a base member 9 having ports 10 leading to the pipes 5, a cover 17 and a distributer 13, the latter being mounted on a rotatable shaft 21 and serving to put each of the ports 10, which are normally in communication with the low pressure space 14<a>, sucessively into communication with the high pressure space 16 to actuate its corresponding valve w.

Filed: 1963-11-02
Abstract: 1,027,885. Aircraft indicators. FERRANTI Ltd. Oct. 29, 1964 [Nov. 2, 1963], No. 43341/63. Heading B7W. Apparatus is described for indicating a departure of a variable quantity, such as aircraft incidence, from a datum value to an extent in excess of permissible limits respectively above and below the datum value. The apparatus provides a steady audible tone when the variable quantity lies within the permissible limits and an interrupted tone when outside them, the rate of interruption indicating the extent of the departure from the datum. Preferably the frequencies of the interrupted tones in the two areas outside the limits differ in opposite senses from that of the steady audible tone, but alternatively only one of these interrupted tones differs in frequency from the steady tone. In one embodiment (Fig. 2, not shown) the error signal e provided, for example, by a potentiometer is converted into square wave form by a chopper 10 connected to a square wave generator 11, is amplified at 12 and fed to a sense detector 13 which supplies one of two signals to an audiofrequency oscillator 15, the frequency of whose output depends on the signal from the detector 13, and to a full wave rectifier 14 the output of which indicates the magnitude of the error signal and is arranged to be a maximum when the error is zero. The operation of the audiofrequency oscillator 15 is controlled by a bistable device 16 with inputs from the rectifier 14, which biases it to a stable state, preventing operation of the oscillator 15 when the error signal is within the predetermined limits and by a variable frequency oscillator 17 so that the output of the oscillator 15 is interrupted at a rate dependent on the error signal. The oscillator output is transmitted through an amplifier 18 to earphones, and the steady tone is provided by the square wave generator 11, and this tone may be cut off by a gate 19 when the error signal increases beyond preset limits. In another embodiment (Fig. 4, not shown) the error signal is introduced as rotation of a shaft of a potentiometer P and switches W1, W2, W3, and the high and low tones are provided by a generator 26, and the medium tone by a generator 25 connected by gates 23, 24, 21 to an output amplifier 20. When the error is within predetermined limits (as shown, with the wipers between B and C), only the gate 21 is opened and only the medium, steady tone transmitted. Outside these limits, one of the switches W2 or W3 is closed and the output of the generator 26 is transmitted through the corresponding gate 23 or 24. This output is interrupted by the operation of a unit 22 comprising a bi-stable device and a variablefrequency oscillator controlled by the output of the potentiometer P. Outside preset limits D and E the switch W1 is opened and the steady tone is discontinued. The aural signals may be supplemented by visual signals, e.g. three lamps may be provided to represent the five conditions set out above.
