Title: Improvements in and relating to electrical amplifying circuits
IPC: G01S13/42
Filed: 1946-10-04
Abstract: 634,438. Valve amplifying circuits. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Oct. 4, 1946, No. 29650. [Class 40 (vi)] A unidirectional voltage across conductors 1 which may vary in magnitude and polarity is fed to a network including valves 8, 9 where it is converted into an alternating potential, the amplitude and phase of which correspond to the magnitude and polarity of the unidirectional voltage. The alternating current is amplified in valve 10 and then fed to a network including rectifiers 11, 12 where it is converted into a unidirectional voltage across conductors 5, 6 which is any desired degree greater than the voltage across conductors 1, 2 and subject to similar variation in magnitude and polarity. Valves 8, 9 have a common cathode resistance 23, and the anodes are connected to separate points on anode resistance 20. When valve 9 is conducting, valve 8 is cut off and vice versa. The potential at 24<1> is dependent on the current through the valve which is conducting at any instant. This may be made the same for both valves and for a given potential on the grid of valve 8, usually zero. With this adjustment, there is no alternating potential at 24 when valve 9 is successively blocked and unblocked by a square wave applied through condenser 19 from an alternating source 15 and limiter 16. When the voltage on the grid of valve 8 deviates from the datum value, an alternating potential appears at 24<1> corresponding in amplitude and phase to the magnitude and sense of the deviation. The alternating potential is amplified at 10 and fed to rectifiers 11, 12 which are arranged to give no potential across points 5, 6 when the square wave from limiter 6 is applied through condenser 18 to both anodes. The alternating potential from valve 10 unbalances the arrangement to a degree dependent on its amplitude and in a sense depending on whether the alternating potential is in phase or out of phase with the square wave from 16. Thus the rectified potential across 5, 6 is an amplified version of the potential across conductors 1. Specification 629,160, [Group XXXV], is referred to.

Title: A process of hydrocarbon oil conversion
IPC: C07C9/14
Filed: 1937-03-08
Abstract: <PICT:0487205/III/1> In a process for cracking oils, of the kind in which the oils are cracked by contact with a heated carrier gas to obtain a fraction of low boiling point suitable as a motor fuel, the residual gas is treated to increase its concentration in hydrocarbons containing more than three atoms of carbon in the molecule by compressing the gas and washing it with an absorbent oil to separate lean gases which are bled from the system, and the enriched fractions are returned to the cracking system for use as the heated carrier gas.  Crude oil is vaporized in a coil 14, flashed in a drum 15 and superheated to 950-1050 DEG  F. in a coil 19.  The vapours are then mixed in a vessel 12 with the carrier gas, which has been heated to 950-1200 DEG  F. in coils 10, and the mixture fed to a reaction chamber 21 where the cracking reaction is completed. The products pass to a fractionator 23 from which heavy residue is withdrawn through a line 24, and through which a light fraction (gas oil) is recycled through lines 26, 28 and a heat exchanger 27.  The products in the gaseous state pass off through a line 32 and a cooler 33 to a receiver 34 where the gasoline product is separated, a portion being recycled as reflux for the tower 23. The residual gases are compressed in a compressor 40, cooled in a cooler 41, and the liquid component is collected in a receiver 42. The gases pass to an absorption tower 44 where the rich gases are absorbed by a suitable menstruum, e.g. a heavy gasoline condensate, which is circulated through the tower 44, stills 48, 50, heat exchanger 46b and line 46a. Unabsorbed gases are evacuated through a line 46, and the enriched oil is stabilized in the still 48 and stripped in the still 50, the rich gases evolved passing through line 51 to coils 10 where they are polymerized at 950-1200 DEG  F. and passed to the mixer 12 as carrier gas for the cracking process.  The lean gases may be passed in part through a line 16 as diluent to the flasher 15.  In a modification the recycled stock is used as menstruum in the absorber 33 and enriched with absorbed gases is fed to the coil 14.  U.S.A. Specification 2,022,221 is referred to.

Filed: 1974-07-10
Abstract: 1458682 Recirculating digital stores GTE INTERNATIONAL Inc 10 July 1974 30641/74 Heading G4A A store for storing binary information comprises a staticizer 12 receiving inputs 12a-12d in binary coded decimal form, the outputs 12e- 12h passing via gates 14, 18 and 20 to 100-bit shift registers 22 so that the binary inputs to registers 22 are skewed by means of clock pulses K 1 -K 7 , from a timing control unit 28, applied to gates 14, different combinations of the input bits at the same time passing via gates 34, 35 and 38 to flip-flops 39-41 which generate and hold error checking parity bits, which are entered, also in skewed form, via gates 44, 46 and 48 clocked by clock pulses K 9 -K 13 , into 100-bit shift registers 42. Information is stored in the staticizer 12 by a "read-demand" signal applied to input 12j, which causes storage, sets the timing to K 1  and resets the flip-flops 39-41. The information is then read into the registers 22 by means of a "start loading" signal SL from the timing control unit 28 which enables the gates 26 and inhibits recirculation of the registers 22. After the pulse K 13 , the inhibiting signal is removed and the registers 22, 42 continue recirculating. After 21 recirculations the stored bits in registers 22, 42 will be once again in the same relative phase as the timing pulses K 1 - K 13 , and during pulses K 1 -K 13  the contents of registers 22, 42 are read into flip-flops 39-41 for parity checking. If no parity error is present in the flip-flops 39-41, this is detected by a gate 54 at the time of pulse K 20 ; the K 21  pulse then resets the flip-flops, resets the timing control unit to K 1 , and the next word is checked. If a parity error is present in the flip-flops, this is detected and used to inhibit pulses K 1 -K 21  and "freeze" the flip-flops. The timing control unit then continues counting to 100 before restarting its cycle. The parity error signals from flip-flops 39-41 pass to a decoder 58a-58g which identifies which register 22 or 42 is in error, an errorcorrecting signal passing to one of the EXOR gates 20, 48 and inverting the appropriate bit in the shift register 22 or 42. At pulse K 21 , the timing control unit resets to K 1  and error checking continues. The binary outputs from the shift registers 22 are delayed by shift registers 32 so that the four outputs arrive substantially simultaneously at an output decoder 30 which produces a decimal output. The details of the timing control unit 28 are given in Fig. 3 (not shown).
