Title: Azaborolidines and their preparation
Inventor: BROWN MICHAEL PETER
IPC: C07F5/02
Filed: 1962-01-31
Abstract: The invention comprises boron compounds of the formulae <FORM:1005232/C2/1> in which R1 is alkyl of 1-10 carbon atoms, or a substituted or unsubstituted cyloalkyl group having 5-7 carbon atoms in the ring; and X is hydrogen, alkyl of 1-10 carbon atoms, a substituted or unsubstituted cycloalkyl group having 5-7 carbon atoms in the ring, or a dialkylamino group in which the alkyl groups contain 1-4 carbon atoms and are the same or different Azaborolidines of the first formula may be made by reacting at an elevated temperature an N-substituted allylamine of the formula CH2 =CH-CH2-NHR1 with a boron compound having at least two hydrogen atoms and a group X bonded to the same boron atom. The boron compound may be diborane, a mono-substituted borane BH2X or a dimer thereof, a borazane of the type R3IVN.BH2X, R2IVNH.-BH2X, or RIVNH2.BH2X, or a borazene of the type R2IVN.BH2 or RIVNH.BH2 (RIV being an alkyl group of 1-4 carbon atoms or aryl). Alternatively there may be used a mixture of a borazane R3IVN.BH3 with a borane BY3, or a adduct of the type BY3.NR3IV in which the Y groups, which may be the same or different, are C1- 4 alkyl, or dialkylamino in which the alkyl groups contain 1-4 carbon atoms and are the same or different.  An inert medium such as a hydrocarbon or ether may be used.  The reaction may take place at a temperature of 50-190 DEG  C. The monomeric product may be separated by distillation.  On standing, e.g. at room temperature, the monomers give rise to the corresponding dimers. Examples describe the preparation of (1) 1-cyclohexyl-2-ethyl-1,2-azaborolidine from triethylamine-borane, triethylborane and allylcyclohexylamine; (2) 1-cyclohexyl - 2 - (di - n - butylamino) - 1,2 - azaborolidine from (Di-n-butylamino)borane and allylcyclohexylamine; (3) 1-isopropyl-1,2-azaborolidine from iso-propyl-allylamine and triethylamine borane; on standing a dimer is formed (4) 1 - cyclohexyl - 1,2 - azaborolidine (and dimer on standing) from allylcyclohexylamine and triethylamineborane.ALSO:Fungicidal compositions comprise one or more boron compounds represented by one or other of the formulae: <FORM:1005232/A5-A6/1> in which R1 is alkyl of 1-10 carbon atoms, or a substituted or unsubstituted cycloalkyl group having 5-7 carbon atoms in the ring; and X is hydrogen, alkyl of 1-10 carbon atoms, a substituted or unsubstituted cycloalkyl group having 5-7 carbon atoms in the ring or a dialkylamino group in which the alkyl groups contain 1-4 carbon atoms and are the same or different, homogeneously dispersed throughout a solid or liquid carrier of a type usually employed in the formulation of fungicidal compositions.

Title: Method and apparatus for compressing data
IPC: G06F17/40
Filed: 1973-01-25
Abstract: 1377594 Compressing data SEISMOGRAPH SERVICE CORP 25 Jan 1973 [16 Feb 1972] 3888/72 Heading G4A Analogue data is converted to digital form and transformed from the time domain to the frequency domain, data values corresponding to frequencies outside a desired range being removed. As described for compressing seismic data from geophones which, after conversion to digital form, is fed either direct to a digital processor 22 (Fig. 1) or temporarily stored on magnetic tape 21 before being fed to the processor, the data is transformed either using hardware 23, or by appropriately programming the processor 22, using the Cooley-Tuckey fast Fourier transform algorithm to derive data values having real and imaginary components each of 16 bits (an appropriate number of zero data values is added to make the number of samples up to a power of two). The complete transform of the seismic data extends from the zero frequency to twice the Nyquist frequency but since the frequency domain plot is symmetrical only values up to the Nyquist frequency are retained. To prevent arithmetic overflow from occurring the input data values may be shifted, the amount of shift being stored to indicate the scaling factor between the time domain and frequency domain versions of the data. The frequency domain data is then limited to the range of interest. If for example the source used to derive the data generates a select frequency seismic waveform between 10 cps and 40 cps only data values whose frequencies lie within this range are retained. The reduced data is then cross-correlated with a frequency domain representation of the source signal by multiplying the amplitudes of corresponding frequency components and subtracting their phases from one another. This reduces the number of data values to be retained by one half. De-convolution is effected by dividing the data by a filtered version of itself to eliminate gross irregularities in the frequency response curve (in the preferred embodiment only the amplitude and not the phase of the data being modified). The 16 bit real and imaginary components of the compressed data values are then trunca ted to for example four bits since the original seismic waveform may be quite accurately reconstructed using these truncated values which are transmitted to core storage in a digital processor 27. Zero data values may be stored to replace the missing data components and a mirror image of the frequency domain data values may also be stored to extend the range back to twice the Nyquist frequency. By performing an inverse Fourier transform on the stored data the original seismic waveform may be obtained, the stored scaling factor being used to rescale the data either before or after transformation. The apparatus may also be used for compressing television or telegraphic picture scans.

Abstract: 1,149,822. Rolling tubes. SANDVIKENS JERNVERKS A.B. 27 Jan., 1967 [1 Feb., 1966; 10 Feb., 1966], No. 4189/67. Heading B3M. Tubes of zirconium or zirconium base alloys (including additives of one or more of Sn, Fe, Ni, Cr and Cb) are made by cold rolling blanks between a pair of grooved pilger rolls, the blanks being reduced in one step by at least 50% while being supported on a mandrel. The rolls may be continuously rotated, or oscillated back and forth. A stand for the rolls is normally stationary, but may, if desired, be reciprocable relative to a stationary tube. A finished tube may be given a final cold working in a drawing die or planetary ball swaging mill, with a reduction of say 4-6% to produce a good surface finish. As shown, a pair of rolls 11, 12 are rotated continuously, and two blanks 18, 18a are reciprocated in synchronism with the rolls. The blanks are carried by a mandrel 17 sup. ported a chuck 62, the chuck being reciprocated in response to the movement of a follower 59 in the cam track 54 of a rotating drum 53. Additionally, a carriage 50 which supports the drum, is indexed by a screw 52 in order to progressively feed the blanks between the rolls. The drives for the drum 53 and screw 52 are synchronized with the rotation of the rolls. The chuck is able to move relatively to a chuck holder 63, by virtue of a spring loaded connection, should the force exerted by the rolls on the tubes exceed a given value. The blanks are rotatably indexed between working strokes by means of a shaft 61, the indexing step being slightly smaller or greater than 60, 45 or 90 degrees.

Title: Preparation of halogenoaliphatic compounds
IPC: C07C17/18
Filed: 1957-02-07
Abstract: Carbon tetrachloride is produced by heating carbon monoxide and chlorine, or phosgene in the presence of a carbon catalyst and a less than one molar ratio of phosphorus pentachloride, relative to the carbon monoxide or chlorine whichever is present initially in the larger amount, or relative to the phosgene.  In place of phosphorus pentachloride there may be used phosphorus trichloride and additional chlorine theoretically sufficient to convert the phosphorus trichloride into the pentachloride.  The phosphorus pentachloride or trichloride is regenerated during the course of the reaction.  The carbon catalyst used is preferably one which has been activated with, e.g. iron and nickel compounds, particularly the halides.  The reaction may be carried out at 1-350 atmospheres preferably at 50-500 DEG C.  When carbon monoxide and chlorine are used as starting materials the initial concentration may be 1 : 10 to 10 : 1 mole ratio, and the carbon catalyst must be present in more than 100% excess of carbon monoxide or chlorine, whichever is present initially in larger amount.  The amount of phosphorus pentachloride present may be between 0,01 and 0,8 moles/mole of carbon monoxide or chlorine, whichever is present in the larger amount.  Examples are given of the preparation of carbon tetrachloride using carbon activated with anhydrous ferric chloride nickel carbonyl and iron carbonyl.

[Class 39 (i)] The electrode in a photo-electric cell is made by forming a layer of metal oxide-such as silver oxide-in the tubes and reducing the oxide by means of a photo-electric metal-such as caesium-introduced into the tube or liberated within it in such a small amount that all the metal is used to form the electrode, so that final evacuation or fixing of excess metal is not required. The metal may be taken up by an adsorbing agent such as zirconium oxide and placed in a vessel, which by fracturing a septum, is put into communication with the main tube, heat, applied to the vessel then driving the caesium &c. into the tube ; or the adsorbed metal in the form of powder may be shaken out of the subsidiary vessel into the main tube. Calcium fluoride may be used as adsorbing agent. The metal may be introduced by decomposing by electrolysis a compound such as caesium chloride or iodide; the compound is held on a metal plate, for example, of silver, which combines with the released gas. In other methods caesium or sodium chlorides can be decomposed by exposure to X-rays. Compounds of graphite such as C8K or C16K may be decomposed by an electric current either in a subsidiary vessel or in the passage connecting the main tube to a vessel holding the alkali metal. Alloys of tin or lead with the alkali metal may be formed, and decomposed by heating by an incandescent electric coil surrounding the alloy.
