Title: Method for the production of ethylene from a liquified natural gas
IPC: C07C11/04
Filed: 1965-08-07
Abstract: Vaporized methane, and ethylene are obtained from liquefied natural gas containing methane and heavier hydrocarbons by fractionating in a first demethanizer to obtain vaporous methane overhead and a heavier hydrocarbon bottoms, cracking the latter to produce a gas mixture containing methane and ethylene, separating the methane in a second demethanizer and passing the liquefied natural gas before fractionation through a heat exchanger to condense reflux for the second demethanizer and subsequently through a heat exchanger to condense reflux for the first demethanizer. Liquefied natural gas from store 10 is pumped by line 11 through heat exchangers 12, 13, 14, 15, 16 and 17 to first demethanizer 20. Vapour may be separated intermediately, e.g. in separator 18. Methane is obtained overhead and partially condensed in heat exchanger 16, vapour being removed by line 29 and liquid being refluxed by line 28. Bottoms may be split into ethane C2 hydrocarbons (line 32), C3 (line 33) and C4 (line 34) by fractionators 21 and 22 for separate cracking in cracking plant 35 or may be cracked without separation. After cooling and drying the combined products are split into two streams in lines 40 and 41 for cooling with methane vapours and liquid respectively before being fed into second demethanizer 23. Overhead is partially condensed in heat exchanger 12 to provide reflux. The bottoms are further separated into ethylene (line 59), ethane/bottoms from fractionator 25) and C3 and higher hydrocarbons (bottoms from fractionator 24). <PICT:1011518/C4-C5/1>

Title: Photoelectric diameter measurer wherein pulse width is a measure of diameter
IPC: B21B38/04
Filed: 1967-08-30
Abstract: Apparatus for measuring the diameter of a hot bar B (Fig. 1) includes an optical system scanning the bar connected to a photo-multiplier 34 which delivers an output pulse 60, the amplitude of which represents the temperature of the bar and the width of which represents its diameter. The apparatus includes a second photo-multiplier 34 connected to the optical system so that the first and second photomultipliers receive signals representing the scanning of the bar in opposite directions. The optical system preferably includes a disc 20 with four circular apertures co-operating with a rotatable slotted disc 28 and six slotted members 30, the slots being such that the bar is linearly scanned. A similar identical measuring system 37B may be placed at right-angles to the first. Diameter measurement.-After amplification the output pulses from the photo-multiplier are fed to Schmitt triggers 82 which enable gates 86 to pass clock pulses representing 0.002 inch increments from amplifiers 48, 50 (180 degrees out of phase) via a gate 194 (Fig. 2) to decade counter 158 (Fig. 3). The second decade B of counter 158 is connected to a reversible counter 160 (Fig. 2) which thus indicates the number of 0.02 inch increments. Temperature measurement.-The output of one of the photo-multipliers is fed to six Schmitt triggers 122, 124, 126, 128, 130, 132 (Fig. 3) which are calibrated to trip at varying voltages to give an output representing the temperature of the bar to within one of seven ranges. A matrix 134 decodes the range to binary form for storage in flip-flops 136, the outputs of which are converted into a signal on one of seven leads which is fed to a printer 142, a display 144A and a shrinkage selector switch 146. Shrinkage correction.-One of the fourteen positions of the rotary shrinkage selector switch 146 is selected in accordance with the material of which the bar is made so that, depending on the temperature of the bar, a signal on one of twenty leads is fed to a matrix 148 which converts this signal to binary form and feeds its complement with respect to 32 into a shrinkage counter 152 (Fig. 2). The signal fed to the matrix 144 represents the amount by which each 0.02 inch of diameter at the measured temperature shrinks on cooling. The shrinkage counter is then repeatedly counted up to 32, the counter 160 being decremented each time counter 152 is full until the count in counter 160 reaches zero when the count is terminated. The pulses fed to counter 152 are also fed to decade counter 158 so that the final count which is printed and displayed represents the measured diameter of the cooled bar.

Title: Switching circuit to control call number transmitters in automatic telephone systems
Inventor: NOTTNAGEL W
IPC: H04Q3/62
Filed: 1967-11-02
Abstract: In a PBX having abbreviated dialling facilities, the output from the automatic dialling device is automatically inhibited if a busy condition e.g. network congestion is encountered at any stage during the setting up of a connection. A calling subscriber TN on gaining access to the dialling device RNG transmits a short code which is stored in KSP. The output from the latter is then translated, at UW, into a full directory number, the digits of which are inserted serially into the cells of store SP. If the call is to a PBX having direct inward dialling facilities contacts dw are operated after the PBX number is inserted in SP and the caller then dials the extension number required into store DSP. No further action occurs until dialling tone is reverted from the main exchange, whereupon relay T in a monitoring circuit TE, comes up. (ln is closed, by means not shown, when cell n in store SP contains a digit of the required directory number, the case where a directory number contains less than n digits is mentioned). Relay ST in the dialler follows and holds. Impulsing relay J is coupled to the first cell in store SP in order to repeat the contents thereof in pulse form to the main exchange. During each impulse train relay V comes up to disconnect T from the trunk. In the intertrain pauses, however, T is reconnected to the trunk and can come up if a busy tone is present thereon. Provided therefore, that the contents of cell 1 in store SP have been read-out, i.e. contact 1 back, relay B follows any further energization of T in order to disconnect the dialler from the trunk. If the initial application of dialling tone is delayed, a timer ZG times-out to effect forced release of the dialler by bringing up B over its II winding. If, instead of dialling tone, busy tone is initially reverted, the dialler does not distinguish between these until after the first impulse train is sent, when relay T comes up for the second time and disconnects the dialler.

Title: Process and apparatus for coating articles
IPC: C03B35/18
Filed: 1968-07-09
Abstract: A sheet 43 Fig. 6 is supported by conveyor rollers 25 between which are positioned, out of contact with sheet 43, hollow rollers 26 formed with radial orifices 29 which may be in the form of projecting nozzles and which may be arranged helically on the surface of the rollers. Pressurized coating or etching fluid is supplied to the interior of rollers 26 and is discharged, as the rollers rotate, on to the surface of sheet 43. The hollow rollers may alternatively be arranged above the sheet, or hollow rollers may be arranged above and below the sheet. When conveyer rollers are used in contact with the sheet, the latter may either be driven or transport of the sheet is effected by fluid discharged from the hollow rollers. When heated sheets, e.g. of glass, are transported by contact with conveyer rollers, the latter may be covered by a material e.g. boron nitride, which does not stick to the glass at these elevated temperatures. In Fig. 9 a duct 1 has a curved upper surface formed with spaced transverse slots 4 and engaged by the upper run of an endless belt 2 supported by driven rollers 3 and formed with aperture 5. Compressed fluid is thereby discharged from duct 1 through the slots 4 and the apertures 5 which thus direct streams on to a sheet 6, the aperture 5 approaching and receding from sheet 6. In Fig. 11 a curved sheet of glass 102 is engaged between upper concave rollers 104 and lower convex rollers 101 either or both of which may be hollow and apertured. Sheet 102 is engaged between the co-operating rollers 101, 104 on its upper surface by concave rollers 107 and on its lower surface by supporting convex roller 105. The apparatus may be used for depositing optical layers on glass, the enamelling of sheet metal and glass, and the etching and silvering of glass. As an example, a sheet of glass, supported vertically, passes between rollers supplied with a 50% solution of industrial hydrofluoric acid for etching through or frosting the glass.

Filed: 1968-07-03
Abstract: In a non-refillable gas-fuelled smoker's lighter, having a flint wheel ignition apparatus at the top of casing 1, a support 2 carries a burner 9 and a flint 4 pushed by a spring 39 against a wheel 29, the lighter also comprising a pivoting operating lever 28 provided with two arms 28b, extensions of which form bearing cams 32, shaft 30 of wheel 29 being mounted in the cams 32, shaft 30 of wheel 29 being mounted in the cams 32, and support of wheel 29 being resilient and comprising two side plates 5a held between two cheeks 1a forming the top portion of two side faces of the casing 1 and having openings 33 in which bearing cams 32 move. Wheel 29 is keyed on a bush 31 through which shaft 30 passes and the wheel 29 carries a ratchet plate 34 engaging with a pawl plate 35 mounted for rotation on bush 31. Pawl plate 35 bears against a projection 36 on operating lever 28: hence plate 35 and consequently wheel 29 turn as lever 28 is pivoted. Burner 9 which is of known construction is provided with a spring-loaded valve-arrangement such that when operating lever 28 in pivoted arms 28b come into contact with a valve lever 22 which then lifts the burner 9, opens the valve-arrangement and allows the escape of gas. Flow of gas is adjusted by compression of a porous washer (15) (Fig. 6, not shown). In operation of the lighter, operating lever 28 is pivoted causing wheel 29 to turn and thus produce a series of sparks by rubbing against flint 4: at the same time arms 28b of lever 28 come into contact with valve lever 22 and turn it around a pivot 40 secured to the top face of support 2. Valve lever 22 then comes into contact with the head of burner tube 9 to allow the escape of gas as previously indicated.

Title: Resin films
IPC: C09J7/10
Filed: 1969-05-31
Abstract: A reticular film or sheet consisting of a "thermoplastic adhesive composition" is made by forming a pattern of spaced apart cuts in the film, the cuts extending therethrough, placing the film upon a supporting surface which is of such a nature it does not prevent movement of the film, heating the film to such an extent that the film material softens and shrinks away from the cuts, whereby the cuts widen to form apertures and the film acquires a reticulated structure. "Thermoplastic adhesive composition" is defined as a solvent-free adhesive composition which at normal room temperatures is in a solid condition in which it is substantially incapable of forming a strong bond with a solid surface but which can be softened and brought to a bond-forming condition by the application of heat, the composition returning to a solid condition on being allowed to cool, and the composition being capable of use in an adhesive bonding process in which the composition is heated to bondforming condition and allowed to cool. The supporting surface used in the formation of the reticulated film may be provided with a coating having "release characteristics" such as a coating of polytetrafluoroethylene or a silicone coating. The support may be a first workpiece which is to be bonded to a second workpiece by means of the web. (For details see Division A3). Preferably the pattern of spaced apart cuts is regular, all the cuts are of uniform length and parallel to one another and arranged in rows extending lengthwise of the cuts. The series of cuts in any one row is preferably staggered with respect to the series of cuts in the adjacent rows. The thermoplastic adhesive composition may comprise a condensation polymerization product of a mixture of 85 mol per cent dimerized linoleic acid and 15 mol per cent azelaic acid with a mixture of 85 mol per cent ethylene diamine and 15 mol per cent hexane diamine, the resulting polyamide containing material having a softening point (ball and ring) of 275 F. and a ball fall viscosity at 355 F.

Title: Regulators for dynamo electrical machines
IPC: H02J7/32
Filed: 1969-08-26
Abstract: The voltage of a D.C. generator 11 (or an alternator-rectifier unit) is maintained at a predetermined value by a conventional transistor regulator comprising transistors TR1, TR2, TR3 and associated components, the regulator input 17a also being responsive to a limiting circuit comprising transistors TR4, TR5, TR6, Zener diode Z2 and associated resistors. This circuit produces an output signal when the generator output current reaches a predetermined value, the current being sensed by a resistor R18 to produce a voltage corresponding to the predetermined current, which voltage drives transistor TR4 out of saturation to turn on the transistor TR6, raise the potential at terminal 17a and so cause the regulator to limit the voltage of the generator. Resistor R12 provides a reference voltage for the limiting circuit whose magnitude is determined by the setting of variable resistors VR2, VR2A and the break-down voltage of the Zener diode Z2. The normal regulated voltage is determined by the setting of variable resistors VR1, VR1A and the connection of the terminal 13 to divider terminal H, M or L.

Title: Apparatus for handling fragile sheets
IPC: B65G49/06
Filed: 1970-02-12
Abstract: The handling of fragile sheet, e.g. glass sheet, because of its fragility, is extremely delicate and difficult. The machines for doing it have been complex and difficult to maintain in satisfactory working order. The present invention remedies these disadvantages in both loading and unloading glass sheet from a support by a machine which picks up the sheet from a horizontal conveyor, turns it to a more or less vertical position parallel to the front receiving face of the support, then moves it in a straight line parallel to the sole plate of the support, the starting position of the sheet being chosen in such a manner that its front edge runs along the said sole plate. If a sheet of glass has already been deposited it is not damaged by the edge of the sheet. In the same way, when this device is unloading, the sheet of glass resting on the support in a more or less vertical position carries out the reverse movement its first motion is in a straight line, which is followed by a rotating movement onto a horizontal surface. This versatile machine can be economically operated and is manufactured at low cost.

Title: Utility meter remote automatic reading system
IPC: H04Q9/14
Filed: 1970-02-12
Abstract: A digital data processing and communications system for a remote utility meter data acquisition system is disclosed. The system employs an electronic interrogator which may be either mobile or fixed. The interrogator transmits an encoded interrogation message to a designated fixed reply station associated with a utility meter. Upon receipt of a properly authenticated interrogation, the reply station transmits the utility meter reading back to the interrogator. The system is so designed that when more than one reply station is within range of the interrogation message, only the one reply station that is addressed in the interrogation message will transmit a reply. Thus, an interrogating operation may be carried out in which many reply stations are interrogated in successive order, with each station transmitting its reply in turn. Transmission between the interrogation station and the various reply stations may be via radio link, acoustic link, electric power line, or a combination thereof.
