Abstract: 1,274,539. Programmed control of machine tools. INTERNATIONAL BUSINESS MACHINES CORP. Nov. 14, 1969 [Dec.30, 1968], No. 55766/69. Heading G3N. A numerically controlled machine tool system incorporates an edge generator 10 for generating numbers representing the position in time of leading and trailing edges of command position square-wave signal DX, DY indicative of the distance of travel for each axis of the machine tool for a given straight-line cut. The output of the generator is fed to X and Y axis position registers 11, 12, the contents of which are compared with that of a reference counter 3 in comparators 13, 14 for each count value after an oscillator 2 has advanced the contents of the counter. Each time that an equal-compare is detected, an output from comparator 13, 14 causes the reversal of a binary trigger 15, 16 and is fed back to indicate to the edge-generator that a new edge number is required. The outputs of the binary triggers 15, 16 form the X, Y command position signals which, together with the reference signal is fed to servo controls and machine tool 9 to cause appropriate movements to take place.

Title: Apparatus for Indicating, Recording and Predicting Local and Distant Thunderstorms
Inventor: FISCHER HEINZ-JURGEN
IPC: G01R13/12
Filed: 1966-12-14
Abstract: 1,175,518. Counters. H. J. FISCHER, and W. SCHMIDT. 14 Dec., 1966 [15 Dec., 1965; 17 Oct., 1966], No. 55994/66. Heading G4D. [Also in Division G1] In an apparatus for indicating and recording lightning strikes a rotatably mounted tuned ferrite antenna A detects signals from the strikes in the frequency ranges 0À5-10 Kc/s. and 1-10 Mc/s. and passes them via a selective amplifier V to a rectifier GL. This produces D.C. impulses, each corresponding to a lightning strike. To determine the average intensity of the strikes the impulses are integrated by a first resistor-capacitor circuit RICI, RI<SP>1</SP>CI<SP>1</SP>, the average being taken over the period determined by the time constant of the circuit (5-60 mins.). The intensity is indicated by the meter JI in series with resistor R 1 <SP>11</SP> across the capacitor C 1 <SP>1</SP>. To count the lightning strikes, the impulses are used to energize relay Re 1 , whose contacts r 1  change to enable the capacitor C 2  to charge from the battery B. When the relay is released, the contacts change back so that C 2  discharges to the much larger capacitor C 2 <SP>1</SP>. The voltage across this is measured by meter J 2  in series with resistor R 2 <SP>11</SP>, to represent the number of strikes. To measure the time for which the strikes occur the output from the rectifier GL is used to trigger a thyristor Th. While this is conducting, a capacitor C 3  is charged from the battery ZI. The charge acquired by C 3  is then determined by the meter J 3 , in series with resistor R 3 <SP>11</SP> to indicate the time. The centre of the thunder-storm is located by adjusting the antenna. Instead of using the capacitive circuits referred to above for counting the strikes, the impulses from the rectifier may be supplied to heat a winding (HW) in an insulated enclosure coupled by a mercury filled capillary to a second enclosure maintained at ambient temperature. The movement of the mercury indicates the number of input pulses. Alternatively a stepping motor may be used to count the strikes (Figs. 3 and 4, not shown). The output indicators associated with the system may have special scales so marked and expanded as to warn of the increasing intensity, and thus the nearness, of the lightning strikes. The indicators may co-operate with a barograph to provide marks on the record thereof representing the lightning strikes as they occur.

Title: Simultaneous dual seismic spread configuration
IPC: G01V1/20
Filed: 1970-11-26
Abstract: 1306586 Seismic exploration PETTY GEOPHYSICAL ENG CO 26 Nov 1970 [24 Dec 1969] 56221/70 Heading H4D Seismic data is recorded by simultaneously using two spreads of seismic detector arrays spaced along a traverse, one spread providing a high and the other a low fold coverage of subsurface common depth points, the respective fold coverages M1, M2, the respective numbers N1, N2 of arrays per spread and the respective intervals D1, D2 between the centres of arrays in a spread being related according to the equation N1.D1/M1 = N2.D2/M2. In the Fig. 1a embodiment for a marine survey, one spread comprises six arrays centred at points 11-16 with a total spread length just less than the interval between successive array centres in the other spread comprising eighteen arrays with centres at 17, 18 &c. By moving the two spreads along by half the interval between array centres of the long spread between shots, 18-fold coverage is obtained from the long spread and singlefold coverage is obtained from the short spread. As reflections from shallow subsurface regions contain predominantly higher frequencies than those from deeper regions, and as the seismic velocity varies more rapidly in the shallow regions, the short spread of arrays provides better resolution of these shallow regions than does the long spread. In view of the different frequency content of data from the two spreads filters for the data may have a higher frequency band-pass for the short spread than for the long spread and in a digital recording system the digital sampling interval may be greater for the long spread than for the short spread (thus reducing the recording capacity needed). For the short spread the normal movement (NMO) is small so that NMO corrections made to the data from this spread will have negligible error. This enables accurate static corrections to be determined and applied to data from the long spread. An initial examination of data from the short spread provides a guide for the economic processing of or recording of the larger mass of data from the long spread: e.g. autocorrelation of short spread data may indicate the type of deconvolution operator needed for removal of multiple-reflections from the long spread data, or conventional velocity-filtering and dipsearching operations on the long spread data may be appropriately modified if steep dip is encountered on the short spread data, or the seismic source operation or long spread data processing may be arranged to take into account bubble oscillations at the source if such oscillations are detected from the short spread data. In alternative embodiments the numbers of arrays per spread or their spacing may be changed to alter the fold coverage. The invention is applicable also to land exploration.

Benzene is separated from a mixture of liquid hydrocarbons additionally containing paraffinic and naphthenic hydrocarbons by introducing the mixture into a multi-stage extractor at an elevated temperature countercurrent to an organic solvent, drawing from the extractor an aromatic-rich liquid extract and a non-aromatic-rich liquid raffinate, cooling the extract to a temperature lower by at least 50‹ C. than the temperature in the extractor and separating it into a bottom phase and atop phase in a decanter, recycling the bottom phase (mainly solvent) to the extractor, azeotropically distilling the top phase (mainly benzene) with acetone, and recovering benzene from the distillation residue. Suitable solvents are diethylene glycol, dipropylene glycol, and sulpholane, and preferably contain 2-15% water as an anti-solvent. The top (benzene) phase from the decanter may be partially recycled to the extractor bottom. The acetone/paraffinic azeotrope may be water-washed to recover the acetone, which may be re-used. Benzene recovery from the azeotropic distillation residue is by rectification. In an example, nitration grade benzene is recovered from a hydrogenated reforming petrol cut, the paraffinic hydrocarbons also being recovered.
