Title: Method and apparatus for compressing urea synthesis off-gas
IPC: C07C273/04
Filed: 1961-03-15
Abstract: <PICT:0927154/III/1> Off-gas from a urea synthesis, containing NH3, CO2 and H2O vapour, is compressed by aspirating the gas into an aqueous liquid solution at super-atmospheric pressure, separating the gas and liquid phases at super-atmospheric pressure and removing the compressed off-gas at super-atmospheric pressure. The pressurized solution may be H2O with 15% NH3 and 13% CO2, NH4NO3, (NH4)2 SO4, Na2CO3 or ammonium carbonate.  A urea process stream 1, containing gas from ammonium carbonate decomposition or comprising product urea solution at 20 p.s.i.g. and 200 DEG F., is aspirated in vessel 2 at 12 p.s.i.a. by a liquid jet exhauster or Venturi or orifice device 3, while a liquid stream leaves at 5.  A liquid stream passes from 6 at 135 p.s.i.a. through 3 thereby entraining off-gas, 35% NH3, 30% CO2 and 35% H2O, from line 4 which leaves at 7 at up to 200 p.s.i.g., e.g. 35 p.s.i.a., to separator 8.  Gas is withdrawn at 9 while liquid collects in 8 and may be recycled via 10 or drawn off at 12 and separately treated or recycled to urea synthesis.  Steam coils 11 can heat 8 to 190 DEG F.  Liquid stream 10 is compressed in pump 13 to 135 p.s.i.a. and may pass via 14 to cooler 15, cooled by H2O (16, 17) and then back to 3.ALSO:Off-gas from a urea synthesis, containing NH3, CO2 and H2O vapour, is compressed by aspirating the gas into an aqueous liquid solution at superatmospheric pressure, separating the gas and liquid phases at superatmospheric pressure and removing the compressed off-gas at superatmospheric pressure. The liquid may be cooled and then recycled to the aspiration step. The off-gas may be obtained from the final aqueous urea solution produced in a urea synthesis by decreasing the pressure to sub-atmospheric.  The pressurised solution may be water with NH3 and CO2 or (NH4)2CO3.  The gas and liquid phases at, e.g. less than 200 psig. may be separated by gravity combined with heating of the separated liquid phase.

Title: Improvements in or relating to polychloro tetrahydro-dicyclopentadiene
IPC: C07C17/04
Filed: 1947-04-09
Abstract: Polychloro dicyclopentadienes containing 4-10 chlorine atoms are prepared by the chlorination of dicyclopentadiene or the hydrogen chloride addition product of dicyclopentadiene.  The chlorination may be carried out in the presence or absence of a solvent and with or without a catalyst.  Chlorine is passed into dicyclopentadiene dissolved in carbon tetrachloride and illuminated with ultra-violet light; samples are taken at intervals up to 40 hours.  The products are recovered and tested for insecticidal activity.ALSO:Insecticidal compositions are made using as the main toxic ingredient a saturated polychloro - tetrahydro - dicyclopentadiene in combination with a carrier material.  The product contains from 52 per cent to 74 per cent of chlorine and preferably between 60 per cent to 70 per cent chlorine.  Additional toxic ingredients may be present; those mentioned comprise a terpene thiocyanoacylate such as isobornyl thiocyanoacetate, fenchyl thiocyanoacetate, and isobornyl - alpha - thiocyanoproprionate, organic thiocyanates such as alkyl thiocyanates, thiocyano ethers such as b -butoxy-b '-thiocyanoethyl ether, rotenone and pyrethrum.  If the material is to be used as a liquid spray it is dissolved in a solvent such as kerosene or dispersed in water to form aqueous sprays.  Insecticidal dusts may be prepared by combining the toxic ingredients with an inert carrier such as powdered carbon, kieselguhr, bentonite or pyrophyllite.
Patent GB-984581-A (GB)
Title: Improvements in or relating to interrogator-responder signalling systems
IPC: G01S13/75
Filed: 1961-03-16
Abstract: 984,581. Track apparatus. GENERAL PRECISION Inc. March 16, 1961 [March 18, 1960], No. 9690/61. Heading B7N. [Also in Division H4]  The responder of an interrogator-responder system is arranged to transmit a response signal having a carrier frequency which is a submultiple of the carrier frequency of the interrogation signal. In this way interference with reception at the response receiver by the interrogator signal is prevented and synchronization is more easily obtained. The system may be used for identifying motor vehicles carrying responders as they pass along a street in which interrogator and response pick-up coils are buried. At the interrogator a carrier frequency from oscillator 26 is modulated by a plurality of audio frequencies from oscillators 26a &c. and supplied to the interrogator coil 22. The signal is received by the tuned circuit 10 of a responder 25, demodulated by diode X1 and capacitor C2 and passed via filters F1, F2, rejecting two of the audio frequencies to modulate a response oscillator 15 which is energized by the D.C. component of the demodulated signal, other responders having different filter arrangements. The resonant frequency of the circuit 16 of the oscillator is a sub-multiple of the interrogator carrier frequency and synchronization is effected by a tapping on coil L1 of circuit 10 supplying a small amount of the interrogator signal to a coil L5 of the oscillator 15. The response signal from the pick-up coil 23 is supplied to a synchronous detector 32 which receives a reference sub-multiple frequency via a frequency divider 33 from the interrogator oscillator 26. Components of the response signal not in correct phase with the reference signal are rejected as noise and the output of detector 32 is supplied through a low-pass filter 34 and amplifier 35 to filters providing a signal to identify the responder. In an alternative form of responder, Fig. 2 (not shown), filters F1, F2 are dispensed with and crystal filters are connected across the circuit 10 to remove certain sidebands, two filters being required for each audio frequency. To prevent this duplication a single sideband signal may be used. This arrangement ensures that the synchronizing signal for the response oscillator is free of any of the frequencies filtered out for identification purposes. Specification 917,755 is referred to.

Title: Improvements in and relating to prepayment gas meters
IPC: G07F15/00
Filed: 1945-04-19
Abstract: 594,019. Prepayment mechanism for gas meters. SMITH METERS, Ltd., and CHARLES, A. April 19, 1945, No. 9849. [Class 27] Complete closure of the supply valve when credit is exhausted is prevented by a spring, e.g., by engagement of a spring plunger 24 on the actuating arm 5 of the valve with mounting plate 3, and the continued action of the meter mechanism is taken by a lost-motion coupling and spring in the drive from the quantity mechanism. A restricted supply sufficient for maintaining pilot lights, e.g., in water heaters, is -thus allowed after. credit is exhausted and the full supply cut off. As shown, the lost-motion coupling is between the quantity differential and the driving-member 11 of a Geneva stop mechanism by which it is connected to the actuating cam 20 for the valve arm 5. Pins 13 on the shaft 10 of the differential engage in circumferential slots in the boss 12 of the driving member 11, and a helical spring 15 maintains the pins at the rearward end of the slots in relation to the direction of rotation under consumption. When credit is exhausted, a slot 22 in cam 20 pivots arm 5 to close the valve, but full closing is prevented by engagement of the spring plunger 24 with the fixed plate 3. Consumption then continues at a reduced rate with the pins 13 working round the slots in the boss 12, against the action of spring 15 and with the quantity differential running into debit. This continues until the pins 13 reach the opposite ends of the slots, when a positive drive is established and the valve is fully closed against the action of the spring plunger 24. When further payment is made, a full supply is not available until the pins 13 have been testored to the rearward ends of the slots as the quantity differential is brought to zero credit. Payment is thus secured for the restricted supply. The spring plunger 24 is adjustably mounted on the valve arm 5 so that the extent of the reduced valve opening can be adjusted. Alternative constructions are referred to in which the lostmotion coupling is associated with the valve cam 20 instead of member 11, or, alternatively, in which the pin 21, by which the cam 20 actuates the valve arm 5, is mounted in a slideway transverse to the valve arm and under the action of a spring. Specifications 387,678, 392,530 and 441,270 are referred to.

Abstract: 556,566. Drawing-tubes. FISHER, HUMPHRIES & CO., Ltd., and KUPHAL, E. G. July 17, 1942, No. 9943. [Class 83 (iv)] Longitudinal adjustment of the mandrel rod in a tube draw bench is effected from a position near the die. The end of the mandrel rod 15 is attached to a bar 11 sliding in a screwed sleeve 6 as limited by a collar 12 and a head 14. To facilitate removal of the bar the collar 12 is split. The sleeve is adjustable in a nut 2 driven at 3 from a reversing motor 5 controlled by a notch located near the die. The nut is restrained from axial movement and the sleeve 6 is prevented from rotating by means of a feather key, splines, or by an arm 7 having a roller 8 running in a guideway in the bench. The arm 7 and a flange 10 limit the movement of the sleeve. The electric motor may be replaced by an air or hydraulic motor or by belt and fast and loose pulleys driven from a line shaft or by a countershaft having a hand wheel &c. at the end near the die. Reducing gear may be incorporated in the chain and in the case of the motor drive a brake may be fitted to prevent overrun.
