Title: Digital data processors and methods of operating such processors
IPC: G06F9/44
Filed: 1975-01-27
Abstract: 1503321 Data processing BURROUGHS CORP 27 Jan 1975 [28 Feb 1974 (5) 13 Sept 1974 (5)] 3416/75 Heading G4A A data-driven data processor includes a store holding a plurality of operators each designating an operation to be performed on data supplied to the processor, and as soon as all the data required for the performance of any one of the operators currently in the store has been supplied to the processor, the operation designated by that operator is performed. The data may be in the form of structures which include an operand and an address identifying the appertaining operator in the store, e.g. by program file and by position within that file. All data may be represented by four characters, 1, 0, (,), each represented by a two-bit code. A program file stored in a store 25 may then be of the form ((A) (B) (C) . . . (D) (E)), A being a description field (for a program A is P) identifying the types of the following fields, E is a terminating field, and B, C and D are fields which may contain operands or operators; for a program file B specifies the operator and C and D being initially empty until the required operands are received by the input queue 21. The program file also includes a destination address field. Operand fields C and D may themselves be one or more program files of the same format (the description field A for each being V); for example each operand file C, D may specify an addition the results of which are subtracted. Each operand file received by an input queue 21 is of the same format, the description field A being L (literal) and being followed by address fields and an operand field. Each step of the program specified by the program file is executed when the required operands have been received by input queue 21. In an alternative arrangement store 25 stores operand files and input queue 21 receives program files while other program files are in storage. To detect errors in the data received by the input queue 21 the left and right brackets in each file are counted, detection of a left bracket, (, causing incrementation of a counter (65, Figs. 2, 6, not shown) and detection of a right bracket, ), causing decrementation of the counter, a non-zero count from the counter after a complete file has been received indicating an error and causing the file to be re-transmitted from an input/output exchange 13. The logic unit 27 includes respective read only memories (125, 129, Fig. 3, not shown) for two-operand and single-operand operations. The control unit 23 includes an analyser (146, Fig. 4, not shown) formed by a read only memory which receives respective data files from the store 25 and input queue 21. The analyser (146) controls three demultiplexors in dependence on the received data file, a received operand file being supplied via one of these demultiplexors to units 25, 27 and 29. On receipt of a program file the analyser supplies signals to three micro-program read-only memories which supply micro-instructions to control the logic unit 27.

Title: Improvements in or relating to echo sounding apparatus
IPC: G01S15/18
Filed: 1934-02-05
Abstract: 416,397. Echo-sounding and distancemeasuring apparatus. ECHOMETER GES., Werk Ravensberg, Kiel, Germany. Feb. 5, 1934, No. 3775. Convention date, March 9, 1933. [Class 118 (ii).] In echo-sounding apparatus arranged to work over a plurality of ranges, the apparatus is arranged to run at a different speed for each range, the intensity and frequency of the emitted sounds are altered for each range and the duration of the emitted sound may also be varied. As shown in the Figure, two ranges are provided, the change-over being effected by switch 9. With the switch in the position shown, the apparatus is suitable for long ranges. The motor 10 drives shaft 14 and cam 17 closes contacts 18 momentarily so that magnet 20 opens valve 21 to allow high pressure air from reservoir 25 to operate the siren or whistle 23. The air from the siren operates contact 8 which de-energizes stationary magnet 1 so that armature 3 is coupled to magnet 2 and carries the pointer 5 with shaft 14. Contact 34 shorts out the receiving transformer 36 for a short time to prevent the apparatus responding to the directly received waves. When the reflected sound is received by receiver 30, magnet 37 is operated through amplifier 40 and opens the circuit to magnet 2 so that armature 3 is again coupled to the magnet 1 and the pointer is held in the position indicating the depth. The pointer is retained for sufficient time for the reading to be observed and then is restored to normal by apparatus not shown. If the apparatus is to be used for shallow measurements the switch 9 is thrown to the right, replacing motor 10 by motor 11 which drives shaft 14 at a faster rate to speed up the rate of emission (controlled by contacts 18). Magnet 29 is operated to connect up the lower pressure reservoir 26 so that the emitted signal is of less intensity, cam 35 replaces cam 34 to short out the receiver for a shorter period and a weakening resistance 33 is connected in parallel with the receiving transformer 36 to give greater freedom from disturbance. A system in which the siren is replaced by a pair of electrically operated automatic pistols is also described.

Title: Improvements relating to the manufacture of fluorides
IPC: C01G1/06
Filed: 1964-01-29
Abstract: A process for making a metal fluoride comprises introducing into a reaction zone a metal having a fluoride which boils below 55 DEG  C. at atmospheric pressure and freezes above the freezing point of anhydrous HF, contacting the metal with NOF.3HF, complex at a temperature in the range - 50 DEG  to +95 DEG  C. at atmospheric pressure and removing the metal fluoride formed from the reaction zone.  In the preparation of WF6, the metal, desirably in particulate form, and NOF.3HF in mol. ratio, e.g. between 1 : 4.5 to 1 : 7.5 are charged to a reactor, the complex desirably being added to the metal over a period.  The reaction temperature is in the range, e.g. 10 DEG to 65 DEG  C. and the gaseous products, WF6, HF and NO, pass into a condenser in which solid WF6 and liquid MF are removed.  The latter may be decanted off and the WF6, containing occluded HF, melted, whereupon two liquid layers form.  Substantially pure WF6 may be withdrawn from the lower layer and distilled.  The HF forming the upper layer may be recycled for preparation of the complex.  Examples of WF6 and MoF6 preparation are given.
Patent GB-759064-A (GB)
Title: Sulphur-containing barbituric acids
Filed: 1954-02-10
Abstract: The invention comprises sulphur-containing barbituric acids of the general formula <FORM:0759064/IV(a)/1> wherein R is an alkyl radical containing 2 to 4 carbon atoms, Y is oxygen or sulphur and X is hydrogen or methyl, and salts thereof. The above compounds may be prepared by standard methods for the production of substituted barbituric acids, the most important of these being condensation of an appropriately substituted malonic acid ester with urea or thiourea, or the mono methyl derivatives thereof.  Instead of the substituted malonic acid esters there can be used other reactive derivatives thereof such as amides, acid chlorides, nitriles, amide-esters or nitrile-esters and instead of the urea or thiourea components there can be used derivatives such as guanidine, isourea ether or dicyandiamidine.  Alternatively unsubstituted or monosubstituted malonic acid derivatives may be used and the missing substituent or substituents introduced subsequent to the formation of the barbituric or thiobarbituric acid ring.  The salts of the barbituric acid products can be formed by reacting the free acids with organic or inorganic bases; the sodium salts are obtained by shaking the acids in an aqueous or alcoholic solution, or in suspension, with the equivalent amount of caustic soda.  In an example (1-methyl) - n - propyl - cyanoacetic acid - ethyl ester is refluxed in absolute alcohol containing sodium with b -methyl-mercapto-ethyl chloride to give b  - methyl - thio - ethyl - (1 - methyl) - n propyl - cyanoacetic acid - ethyl ester.  This compound is then condensed with urea by refluxing with sodium in absolute alcohol and the resulting b  - methyl - thio - ethyl - (1 - methyl) - n-propyl-cyanoacetylurea on boiling with sulphuric acid gives 5 - b  - methyl - thio - ethyl - 5 - (1-methyl)-n-propyl-barbituric acid.  The sodium salt is prepared by reaction with caustic soda.  In further examples compounds of the above general formula wherein R, X and Y have the following values are prepared similarly: (1) R = Et, X = H, Y = S; and its sodium salt.  (2) R = n-Pr, X = H, Y = S; and its sodium salt.  (3) R = iso-Bu, X = H, Y = O; and its trimethylamine salt.  (4) R = iso-Bu, X = H, Y = S; and its sodium salt.  (5) R = n-Pr, X = Me, Y = O; and its sodium salt.  (6) R = n-Pr, X = Me, Y = S.  (7) R = Et, X = Me, Y = O; and its sodium salt.  In a further example b  - methyl - thio - ethyl - (1 - methyl)-n-butyl-cyanoacetic acid ethyl ester in methanol is condensed with guanidine carbonate in benzene, in the presence of sodium.  The resulting b  - methyl - thio - ethyl - (1 - methyl) - n-butyl-cyano acetyl guanidine on boiling with sulphuric acid yields 5-b -methyl-thio-ethyl-5-(1-methyl)-n-butyl-barbituric acid. Specification 595,867, [Group IV), is referred to.
