Title: Process for the transformation of the interior structure of clouds
IPC: A01G15/00
Filed: 1973-06-15
Abstract: 1434112 Influencing meteorological conditions PHILAGRO 15 June 1973 [16 June 1972 20 Nov 1972 29 May 1973] 28591/73 Heading A1X A process for transforming the interior structure of clouds to prevent hail-storms comprises igniting an explosive mixture of acetylene and air in burner 13 fitted with an upwardly directed open chimney 14, thus producing a shock wave, which, when directed to hail forming clouds, modifies their internal structure. The explosions are repeated every 8-15 seconds to achieve optimum efficiency of transformation and coils. Acetylene either from cylinders or produced from the reaction of calcium carbide and water, cleaned and purified in a scrubber 3 and purifier 6 is passed to a three way valve 8, one outlet passing to a gasholder 10, another to the burner 13 and the third to a pilot jet 11. The heavy gauge steel cylinder burner 13 of diameter D has an air inlet 13a in the lower casing covered by an internal, pivoted, counterweighted or spring loaded flap arranged to close to an angle of 20 with the wall. A chimney 14 of inverted frusto-conical shape is fixed to the upper conical portion of burner 13 forming a cylinder 30 of diameter "d" at the junction. In operation, gas fed from valve 8 to holder 10 is exhausted into burner 13, where it mixes with air drawn in from inlet 13a. Pilot jet 11 then ignites the mixture and an expolsion occurs, producing an upwardly directed shock wave. The explosion also causes the flap over inlet 13a to rebound, and permit a sudden entry of air, which contributes to satisfactory shock wave formation and propagation, improved by the presence of cylindrical portion 30. Optimum results are obtained when the expolsions are repeated at 8-15 second intervals, and where a burner of height 3D, the ratio D/d is between 4:1 to 2.5:1. Embodiments using automatic gas supply and ignition timing valves which operate on batteries Figs. 4, 5 (not shown), and the use of alternative and premixed explosive mixtures and alternative ignition mechanism i.e. spark plugs, pietzo-electric crystals, electrical resistances are described.

Title: Method and apparatus for searching and adding records to a  sequential file in a small computing system
IPC: G06F12/00
Filed: 1973-06-18
Abstract: 1418837 Digital storage systems BURROUGHS CORP 18 June 1973 [3 July 1972] 28762/73 Heading G4C A sequential file in a slow access store is associated with a fast access store in which there is set up an index table which is used in the locating of a required record in the file. The index table comprises key words indicating the boundaries of partitions into which the file is notionally divided, each such partition containing a number of records. If a required record is not in a selected partition records added to the file subsequently to the formation of the partitions are searched. The accessing and the assembly of the table are controlled by a program controlled processor. Prior to the file being accessed a number NP is calculated. NP is the number of records in a partition of the file and is (MX/C) + 1 where MX is the known number of records in the file and C is the number of indexed (or keys), each of which defines a partition. The key of the ordinal number of the NPth record, i.e. of the record at the end of the first partition, is now read and is stored in the first location of the fast access store. The key of each succeeding NPth record is similarly recorded in successive locations until the index table is complete. To locate a required record a search is first made through the table. The search routine (Fig. 5A, not shown) determines the locations in the fast access store of the key of the partition containing the record and of the preceding partition. The location numbers are converted to record numbers by multiplying them by NP (Fig. 5B, not shown). The higher number is incremented by one and the lower is decremented by one. The keys of successive records in the partition so defined are now compared with the search argument until the required record is found (Fig. 5C, not shown). However should the record not be found in that partition those records that have been added to the file after it was opened are now searched. Such added records are later sorted into sequences.
