Title: Variable exponent computer
IPC: G06F5/01
Filed: 1961-01-13
Abstract: 902,030. Electric calculating apparatus. BENDIX CORPORATION. Jan. 13, 1961 [Jan. 18, 1960], No. 1460/61. Class 106 (1). A digital computor capable of operation with (a) floating point or (b) in a " variable exponent '' mode is shown with a switch 42 for changing the mode. Number representation is (a) with numbers in parts N of registers R1-R3 and their-exponents in parts E, and (b) with numbers filling R1-R3 and the exponent being called separately from memory M to a register R4. Calculation (limited to addition and multiplication in the embodiment shown) is effected by (a) (switch arms to right) sending the numbers from R1, R2 to number inputs of the arithmetic unit A over lines 16 and 18, and the exponents from R1, R2 to exponent imputs 20, 22, when the numbers and exponents are operated upon in conventional floating point arithmetic manner to produce a result number and exponent supplied to register R3; (b) (switch arms to left) sending the numbers from N and E parts of R1, R2 over lines 16, 28 and 18, 36, the exponent stored in R4 being sent to imputs 20, 22. A sends the number and exponent of the result to R3, the exponent being possibly greater than that stored in R4. An " operation completed " signal from A sets 74 so that pulses from pulse generator 76 will pass " and " gate 72 if comparator 62 indicates non-identity between the exponents in R4 and R3. These pulses count down the exponent in R3 and shift the number in N upwards, until the exponents are equal, when the calculation result is expressed in corrected form for storage.

Title: Electrochemical oxidation process
IPC: C25B3/23
Filed: 1972-01-12
Abstract: 1377681 Oxidation of benzene etc ELECTRICITY COUNCIL 12 Jan 1972 [12 Jan 1971] 1472/72 Heading C7B Electrolytic oxidation of an organic compound e.g. benzene, naphthalene, toluene, dissolved or suspended in an electrolyte is effected by passing the electrolyte through a mesh anode comprising a titanium substrate having an electro-deposited coating of lead dioxide. The electrolyte may be sulphuric acid and may contain a solvent such as acetone. The anode may be of the type disclosed in Specification 1373611. The cathode may be solid lead or titanium mesh. In Fig. 1 the mixture of benzene and sulphuric acid is passed from pump 1 to cell 2 where some of the benzene is oxidized to p-benzoquinone. The electrolyte passes via filter 3 and heat exchanger 4 to separation vessel 6 where p-benzoquinone rich solution being less dense is run off through tap 9 into a distillation flask 10. The benzene rich solution being more dense is returned to the cell via pipe 8. Cathodic hydrogen liberated in the cell separates from the electrolyte in the heat exchanger 4 and passes off through pipe 5.
