Title: Cracking and reforming of hydrocarbons
IPC: C10G57/02
Filed: 1942-07-06
Abstract: <PICT:0561048/IV/1> Hydrocarbon distillates are cracked and reformed by comingling the distillate with a light fraction produced in the process and comprising predominantly butane and pentane, subjecting the mixture to cracking under pressures of 500-2000 lbs per sq. inch at temperatures of 950-1100 DEG  F., fractionating the cracked products to recover a gasoline distillate and a lighter fraction, polymerising and alkylating the olefines in the lighter fraction, separating from the products obtained a fraction comprising chiefly pentane and butane and returning the latter fraction as the light feed to the cracking stage.  The feed may be purified before treatment by extraction with sulphur dioxide, nitrobenzene, methylacetate, phenyl acetate, methyl or ethyl cellosolve, furfural, acetone, aniline, cresylic acids dichlorethyl ether or phenols.  A distillate comprising straight run naphtha is fed through line 1 and mixed with a light feed produced in the process and recycled through lines 5, 3 is cracked at 1000 DEG  F. and 500-2000 lbs. pressure in coil 6 the products are passed through a series of fractionators 9, 12, 18 controlled to recover tar and gasoline fractions through lines 10, 14 and an overhead fraction comprising hydrocarbons having three or less carbon atoms in the molecule.  The pentane-butane fraction is withdrawn through line 20 and passed to a reactor 26 where the olefine content is polymerised, e.g. by treatment at 440-500 DEG  F. in presence of phosphoric acid catalyst the reaction being regulated to produce mainly the iso-olefines.  The remaining gases are alkylated in a reactor 27 in presence of sulphuric acid.  The products after separation of gasoline fractions are recycled through line 5.

Title: Electrical digital computing engines
Inventor: CLAYDEN DAVID OSWALD
IPC: G06F7/52
Filed: 1956-03-27
Abstract: 799,900. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 27, 1957 [March 27, 1956], No. 9495/56. Addition to 777,839. Class 106(1). The electrical binary series-mode divider described and claimed in the parent Specification, is modified so as to be capable of performing multiplication. The multiplying arrangement is similar to that described in Specification 717,114. In the preferred embodiment, Fig. 3, the digit pulses are widened from <SP>1</SP>/ 3  to 1 microsecond as described in Specification 718,901 to eliminate errors due to timing discrepancies. The word length is 32 digits (including a sign digit) corresponding to pulse times P1 to P32. The timing is divided into odd and even minor cycles corresponding to the circulation of the first and second words contained in the double length store DLS. For division, a long pulse DIV is applied to the gate 16 and to the delay 31 beginning near the end of an even minor cycle and remaining on for 65 minor cycles to end at even P1 time. The contents of the double length store DLS are the dividend (later the remainder) and the quotient and these circulate through the adder/subtracter 4 via the gates 72 and 28, division taking place as described in the parent Specification. If the circuit is to multiply, a long pulse MULT having the same timing as the pulse DIV is appried to the delay 68 and to the addersubtracter 4 which functions as an adder via the gates 74 and 30. The digit sensing trigger circuit 3 is now operative and is put on at the beginning of even P time by a wide P 1 pulse acting at the gate 76 if the sensed multiplier digit is a " 1 " to thereby gate one copy of the multiplicand from the single length store SLS through the adder 4 via the gate 18. The MULT pulse applied to the adder 4 is operative to suppress during multiplication the normal round carry which takes place therein. A logical circuit for generating the required long MULT and DIV pulses is described (Fig. 4, not shown). Specifications 700,007 and 717,115 also are referred to.

Patent GB-421308-A (GB)
Title: Improvements in or relating to the production of titanium compounds or pigments
IPC: C22B34/12
Filed: 1934-03-27
Abstract: In a cyclic process for the production of titanium compounds, titaniferous materials such as ilmenite are treated with hydrochloric acid as by heating in a closed vessel under pressure to dissolve impurities such as iron compounds which are removed, the remaining titanium concentrate is dried and chlorinated, as by mixing with reducing material and treating with chlorine at 600--700 DEG  C., and the titanium chloride so obtained decomposed, as with water or steam, to recover hydrochloric acid for re-use.  The chloride or chlorides obtained by the hydrochloric acid treatment may also be treated to recover acid for re-use, and the oxides, for instance, iron oxide so produced, be used for the production of pigments.  The titanic acid obtained from the titanium chloride is washed and calcined in the presence, if desired, of neutralizing agents, sintering agents, or compounds of phosphorus, to produce a pigment, and by decomposing the titanium chloride in the presence of a carrier such as barium sulphate, composite pigments may be obtained.  In the treatment of the initial material with hydrochloric acid, the presence of salts of metals having a variable valency accelerates the reaction.  Salts of titanium, iron, manganese, chromium and vanadium may be used, and may often be introduced by using the wash-waters obtained from different steps of the process.

Title: Improvements relating to refractometric cells
IPC: G01N21/41
Filed: 1954-04-02
Abstract: 750,727. Refractometers. LKB-PRODUKTER FABRIKSAKTIEBOLAG. April 2, 1954 [Oct. 16, 1953], No. 9758/54. Class 97 (1). A refractometer cell comprises one pair of parallel outer walls and at least one pair of mutually parallel inner walls, inclined to the outer walls, which together with the outer walls, enclose the medium of unknown refractive index and also define compartments outside the inner parallel walls to house a reference medium. In the examples shown the unknown substance is contained in the central compartment and the reference medium in the outer compartments of triangular section. In each case two rays, such as shown, are deviated in opposite directions and their relative deviation is measured. It is shown that, as compared with a cell having a single diagonal separating wall the deviation is a linear function of refractive index difference for a much larger range of values of such difference. A cell may be constructed with identical but separate arrangements of compartments superposed, so that different reference substances may be compared with a single unknown substance which, if flowing, may pass through compartments at different levels successively. Alternatively the inclined walls at the different levels may be differently inclined to the outer walls so that, using a common reference substance, different sensitivities are obtained at the different levels. Cells for reference media may be replaced by solid prisms of, for example, glass.

Title: Improvements in and relating to recurrent generators
Inventor: THOMAS DAVID CALDWELL
IPC: H03K5/00
Filed: 1953-04-10
Abstract: 741,580. Pulse generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd. April 12, 1954 [April 10, 1953], No. 9798/53. Class 40 (6). A system for generating a train of pulses comprises two pulse generators, each of which will produce an output pulse having a delay with respect to a triggering input pulse which is variable as a function of the phase and number of oscillations produced by an oscillatory circuit in each generator; the generators operating alternately by causing each output pulse from each generator to effect the triggering of the other generator. Fig. 2 shows a pulse generating system comprising two pulse generators 10, 11 each of which, as shown in Fig. 1, comprises an exciting circuit 1 which is triggered by an input pulse at terminal 4 to initiate a train of oscillations from resonant circuit 3, the same pulse also switching out of circuit the damping circuit 2. The train of oscillations is fed to variable phase shifter 5, counter or frequency divider 6 and pulse-forming circuit 7 so that by adjustment of the phase shift in unit 5 and the count of unit 6 the output pulse at terminal 8 can be given a predetermined time delay with respect to the input pulse at 4. The output pulse from unit 7 is fed back to switch off the exciting circuit 1 and switch on the damping circuit 2 which damps out the oscillations from the resonant circuit 3. In the system shown in Fig. 2 the output from each of the pulse generators 10, 11 is fed back into the input of the other so that the system once triggered by a pulse at input 12 is self-sustaining. In a modification, shown in Fig. 3, duplication of the elements of each of the two pulse generators is avoided by the use of a common phase-shifter 5, counter 6 and pulse former 7. An output pulse from unit 7 changes over the bi-stable trigger-pair circuit 23 to energize a given exciter unit, for example 18, to generate a train of oscillation from resonant circuit 15 which is applied via switch 17 to units 5, 6 and 7, at the same time damper 21 is energized to stop oscillations from unit 16. The next output pulse changes back trigger circuit 23, the output pulse from which excites unit 19 and damps unit 20 so that pulses are obtained from resonant circuit 16. Switch 17 is itself controlled by trigger circuit 23.
