IPC: G01N30/16
Filed: 1968-10-29
Abstract: 1,230,202. Continuous gas chromatography. TEXACO DEVELOPMENT CORP. 29 Oct., 1968 [16 Nov., 1967], No. 51120/68. Heading B1L. A continuous process for monitoring process streams by means of gas chromatography comprises passing the sample from source S, to control valve 11 which periodically releases increments thereof to vaporizer 13, where it is entrained in carrier gas supplied by line 14 from source S 2 . The mixture then passes by line 15 to inlet control valve, controlled by timer 22, which passes the stream to, say, column 19 of the plurality of columns 19, 20, 21 &c. These columns are packed with a stationary phase which does not sorb the component being monitored, but does sorb the others. The unsorbed component flows through line 30 outlet control valve 36 and line 37 to thermal conductivity detector 39, which is also supplied with comparison carrier gas by line 40. The signal produced is recorded and may be used to operate a process controller. While column 19 is on stream, columns 20, 21 are being desorbed with purge gas supplied by line 18, valve 17 and line 27 or 28 from source S 3 , desorption suitably being assisted by heating through coils 42, 43, and the desorbed material being vented by line 41 from valve 36. Before breakthrough of the sorbed components occurs in column 19, timer 22 switches valves 17, 36 to bring on-stream a desorbed column, and to start the desorption of column 19. In another embodiment (see Fig. 4, not shown), the purge step is achieved with carrier gas, only two columns being required. For use in detecting the presence of non-normal paraffins in C 10-15 -n-paraffin streams, a zeolite molecular sieve is used as column packing, and helium as carrier gas, the columns being maintained at 150-190C for the monitoring step and 290-350C for the desorption step. If desired, the process stream may be supplied to the column continuously. The process may be applied to the monitoring of (a) gaseous impurities in a carbon dioxide stream, using a zeolite molecular sieve, (b) removing aromatics from saturated hydrocarbon streams, using sulphuric acid on silica gel, and (c) analysing alcohols, using boric acid on crushed firebrick.

Abstract: 1,233,405. Radio navigation. HOFFMAN ELECTRONICS CORP. 26 June, 1968 [3 July, 1967], No. 30540/68. Heading H4D. In an arrangement for rejecting co-channel interference wherein the wanted signals are a pulse train with predetermined pulse spacing and amplitude, a detector 12, Fig. 2, passes all pulses of amplitude above a first threshold, a circuit 14 produces an output if such passed pulses have the predetermined spacing, a a detector 38 passes pulses of amplitude above a second threshold higher than the first threshold, and an AND gate 18 is provided. The invention is applied to a TACAN receiver, A, Fig. 1, being the composite wanted signal input envelope, B the 15 c/s. modulation envelope, C the composite signal envelope from an interfering TACAN beacon and D a 50% threshold of A; in the absence of the invention false TACAN reference pulse bursts occur when curve C is above curve D. (In a TACAN system the main reference burst, transmitted when the ground beacon points due north, comprises 12 pulse pairs, the pulses in the pairs being separated by 12 microseconds and the pairs themselves being separated by 30 microseconds, and the auxiliary reference bursts, transmitted at every 40 degrees, each comprise 12 pulses separated by 12 microseconds.) When either bi-stable 22, 26, Fig. 2, is set, OR gate 28 feeds an output to AND gate 40. If circuit 14 produces an output on line 16, and if one received pulse exceeds the high threshold, gate 18 enables AND gate 40 to set bi-stable 42 which thereby permits gates 32, 36 to pass a pulse on either of lines 30, 34 to indicate that an auxiliary or main reference pulse group has been received. The trailing edge of the pulse on either of lines 30, 34 causes OR gate 44 to reset bi-stable 42 and to close gates 32, 36. A counter in circuit 14 resets bi-stables 22, 26 and the process is repeated for another group of pulses. An embodiment of circuit 14 incorporates counters 50, 58 and 64, Fig. 3, multivibrators 52, 56, 60, 66 and AND gates 54, 62, 68.

A surface 29 is shaped to be complementary to the end 30 of a stud so that as a stud is pushed out over the edge 27 it is able to fall flat end first down the shoot 17 if the flat end is leading. If the end 30 is leading the stud cannot pivot about the edge 27 and the end 30 rides up a ramp 33 until the flat end clears the edge 27 when the stud again falls flat end first down the shoot. A pin 34 prevents studs being forced back up the shoot 17. From the shoot 17, Fig. 1, the studs pass to an escapement mechanism 18 from which they are pneumatically propelled through a tube 19 to a gun 20. In the escapement mechanism 18, Fig. 6, the studs fall one at a time into a recess 45 in a pneumatically operated piston 44 which moves them into alignment with a feed part 19 through which they are ejected.

The term "wholly supported" includes supporting the roving so that it is bridging a gap which is less than the effective staple length of the majority of fibres in the roving. As shown, a roving is drafted in two stages at x and y and is fed without draft around the surface of roller 6 to emerge from the nip between rollers 6 and 7. The roving is then twisted on a ring and traveller. The nip prevents the twist running back to the drafting stages. In alternative embodiments, the further stage is formed between two pairs of closely spaced rollers, (Fig. 2), or between aprons (Fig. 3).

Detectors 18, 19 are connected to respective amplifiers 22, 23, and trigger circuits 24, 25 for controlling logic circuit 28, the state of which is indicated by lamps 29, 30. The logic circuit controls relay driver 33 and thence relay 34, which provides timed input signals to computer input 37. Detector amplifiers.-Each detector 18, 19 is a photocell 45, Fig. 2, connected to an FET phase splitter 41 feeding emitter follows 56, 57 provided with a diode OR-gate 76, 77 to pass positive going signals to output 82. Logic circuit 28, Fig. 3.-This circuit is actuated first only by trigger 24 (on input 85) to produce a first pulse at output 118, and subsequently to respond only to an output from trigger 25 (on input 86), producing a second pulse at 118, after which subsequent trigger pulses at 85, 86 have no effect until the circuit has been reset by switch 110. On receipt of the first trigger input at 85, SCR 92 (in reset condition being off) is switched on (lamp 96 being illuminated thereby). This results in SCR 100 (in reset condition being off) being switched on, a negative pulse via capacitor 107  causing SCR 106 (in reset condition being on) to be switched off. A positive pulse results through capacitor 115 and diode OR circuit 119, 120 to apply a signal to the relay drive on 118. The subsequent trigger pulse on input 86 results in switching on of SCR 106 and switching off of SCR 100 (via capacitor 107). A resultant positive pulse passes via 127 and OR gate to the relay driver. Before initiating a subsequent measurement sequence, the circuit is reset by 110.

After a delay timed by 155, 158, unijunction 145 actuates SCR 142, to turn off SCR 141 and terminate energization of relay 149.
