Title: Information storage and recognition
Inventor: WATRASIEWICZ BOHDAN MACIEJ
IPC: G06V10/88
Filed: 1967-06-12
Abstract: 1,202,551. Holography. BRITISH AIRCRAFT CORP. Ltd. Sept.12, 1968 [June 12, 1967], No.27059/67. Heading G2J. [Also in Division G4] A method of searching for a character in a plurality of characters comprises forming a multiple hologram containing the plurality of characters in a recording medium using electromagnetic radiation, placing the hologram in a beam of coherent radiation and rotating the hologram in said beam whereby successive holograms are brought into operative position and viewing the beam transmitted through the hologram through the Fourier filter of the character being searched. The recording medium is preferably a photographic plate. The multiple hologram may be recorded by passing a coherent beam of light both through a transparency of a character to be recorded as object beam and through a rotatable prism as reference beam. For each exposure of a different transparency the prism is rotated to vary the angle of incidence of the reference beam, the multiple hologram then having each successive hologram in a plane at a small angle to the plane of the adjacent holograms. A Fourier transform is made of the character to be searched. Thus in re-construction a multiple hologram 14 is illuminated with a beam of coherent light from a source 32. The constructed image of the hologram is viewed through the Fourier filter 20 of the character to be searched from a back focal plane 50 of a lens 34, the filter being at the common focal plane of lenses 33, 34 and the hologram 14 at the front focal plane of lens 33. The multiple hologram 14 is rotated to bring each separate hologram into operation and if one corresponds to the character a bright spot will occur, the position and identification of which is known. If desired the output can be fed to a Vidicon tube synchronized with a cathode ray tube or with an analogue/ digital converter linked to a digital computer.

Title: New monoazo dyestuffs
Inventor: ANDREW HERBERT FRANCIS
IPC: C09B62/085
Filed: 1960-08-04
Abstract: The invention comprises monoazo dyes of the formula <FORM:0948160/C3/1> wherein R represents a radical of the benzene or naphthalene series containing at least one sulphonic or carboxylic acid group, X represents a bromine atom or a chlorine atom and Y represents an amino or substituted amino group containing up to 12 carbon atoms.  The radical Y may be derived from such amines as methylamine, 2-hydroxyethylamine, aniline and anilines substituted with sulphonic or carboxylic acid groups or both sulphonic and carboxylic groups.  The dyes are produced by reacting (a) ammonia or an appropriate amine with an appropriate dihalotriazinyl aminobenzene azo dye or (b) an appropriate aminobenzene azo dye with an appropriate dihaloaminotriazine or (c) by coupling an appropriately substituted aniline with an appropriately substituted pyrazolone. Many starting materials are listed. Examples are furnished. Specification 876,923 is referred to.
Patent GB-934986-A (GB)
Title: Refining the liquid hydrogenation products of coal
IPC: C10G1/04
Filed: 1960-08-04
Abstract: The liquid products of the hydrogenation of coal are refined by the addition of (a) a precipitating agent, and (b) a coagulating agent comprising sulphuric or aminosulphonic acid, separating the resulting liquid phase from the sludge phase, and removing the precipitating agent (a) from the liquid phase, suitably by distillation.  The residual sludge is preferably then extracted with acetone, after which the sludge is dried, e.g. at 110 DEG C., yielding a coke containing pitch, while the acetone is distilled off from the extract.  The preferred additive (a) is toluene, xylene, and particularly benzene, but heptane may, for example, be used if the presence of medium or heavy pitch in the liquid phase is unobjectionable.  In general, 50-100 lbs. of (a) and 2-5 lbs. of (b) are used for every 100 lbs. of material treated, and the process is generally carried out at below 35 DEG C.  Instead of extracting with acetone, residual oils may alternatively be recovered from the sludge by distillation.  The process may be performed continuously or batchwise as preferred.

Abstract: 1,159,571. 1-#-D-Arabinofuranosyl cytosine phosphate derivatives and intermediates therefor. UPJOHN CO. 17 June, 1966 [28 June, 1965], No. 27139/66. Headings C2A and C2C. The invention comprises 1-#-D-arabinofuranosyl-cytosine (and 5-substituted cytosine) 2<SP>1</SP>- and 3<SP>1</SP>-phosphates and intermediates therefor of the formulae:-:- wherein X is H, CH 3 , CF 3 , F, Cl, Br or I, Ac is the acyl group of a hydrocarbon carboxylic acid containing from 2 to 12 carbon atoms or is anisoyl, and T is triphenylmethyl, p-(methoxyphenyl) diphenylmethyl or bis-(p-methoxyphenyl) phenylmethyl. They may be obtained by treating a compound of formula or salt thereof, e.g. the HBr or HCl salt with an etherifying agent, TBr or TCl, in a basic organic solvent to form the corresponding ether (II), treating II with an appropriate acylating agent (acid chloride, bromide or anhydride) and treating the resulting acylated product (III) with an alkali base at from -10 to +10 C. for less than 60 minutes to form a compound (IV) of formula and treating the latter with a phosphorylating agent, preferably 2-cyanoethyl phosphate, in the presence of a condensing agent and then with an alkali base at low temperature to give a mixture of V and VI which may be separated by chromatography or which may be treated with aqueous acetic acid and then with an ammoniacal alkanol and the resulting mixture chromatographically separated to yield compounds VII and VIII. The latter compounds can also be obtained by direct phosphorylation of compound II with a phosphorylating agent in the presence of a condensing agent, e.g. dicyclohexyl carbodiimide, and then treating with an alkali base to give etherified 2<SP>1</SP>- and 3<SP>1</SP>- phosphates which on treatment with aqueous acetic acid yield compounds VII and VIII. In another method compounds I are directly phosphorylated with 2-cyanoethyl phosphate in the presence of a carbodiimide to give a mixture of the 2<SP>1</SP>-, 31- and 5<SP>1</SP>-phosphates which can be separated from each other by chromatography. The compounds VII and VIII show cytotoxic activity in vitro particularly against KB tumour cells and viruses, e.g. Herpes, Coe and Vaccinia viruses. They are also useful for cleansing glassware and instruments used in the growing of cultures for virus and tumour research, for washing excised tumour tissue, and for preparing cultures of micro-organisms, e.g. phage-free antibiotic - producing Streptomyces cultures. They may also be condensed with other nucleosides in the presence of condensing agents to form oligo-nucleotide polymers.

Patent GB-365613-A (GB)
Title: Improvements in the working up of oxidation products of hydrocarbons
IPC: C07C51/487
Filed: 1930-09-15
Abstract: The oxidation product of difficultly volatile hydrocarbons or an acid fraction thereof is treated to destroy the hydroxy-carboxylic acids by splitting off water by heating above 100 DEG  C. while avoiding distillation; for instance the material may be allowed to stand for several hours at 150-250 DEG  C. at any pressure and preferably in the presence of catalysts promoting the splitting-off of water from hydroxy-compounds, such as mineral acids or their anhydrides, sulphonic acids, and zinc chloride. This treatment may be effected in the absence of oxygen, for example, in presence of nitrogen or other inert gas, and may be combined with other processes such as bleaching with gaseous reducing agents such as hydrogen or sulphur dioxide or agents supplying the same such as bisulphites but excluding treatment with oxidizing agents.  When employing these bleaching agents, for instance, hydrogen in presence of nickel, the presence of a catalyst promoting splitting off of water is necessary, as otherwise reduction to alcohols is liable to occur.  In examples: (1) a product obtained by oxidizing with air at 150 DEG  C. a fraction of Russian gas oil (b.p. 180-350 DEG  C.) in a vessel filled with Raschig rings or the like, is treated for 4 hours at 250 DEG  C. and 50 atmospheres pressure with hydrogen and finely-divided nickel in presence of b -naphthalene sulphonic acid; (2) an oxidation product obtained in a similar manner from paraffin wax is heated to boiling at 250 DEG  C. at 150-200 mm. mercury gauge under a reflux condenser for 4 hours; (3) the same oxidation product is heated as before but under 50 atmospheres pressure; (4) an acid product obtained by saponification of a paraffin-oxidation product and decomposition with acid of the soap, is heated for 2 hours at 250 DEG  C. in nitrogen. Specifications 322,437, [Class 2 (iii), Dyes &c.], and 352,537 are referred to.

Abstract: 773,613. Mixing liquids in flow. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 8, 1955 [Sept. 24, 1954], No. 27634/54. Class 86 [Also in Group I] Apparatus for adding chemicals to water in a reservoir in proportion to the discharge of the water therefrom comprises two vertical co-axial cylinders 2, 3 of equal length the inner one, 3, being closed, as by a cover 9, at the top and opening through holes 4 near the bottom into the outer cylinder 2 which is. open at the top through holes 7 and at the bottom through an outlet 5 in the common bottom of the cylinders, the outlet pipe 5 dipping into a small cup 6 attached to the bottom of the cylinders and open to the reservoir.. Briquettes of the chemicals are placed in the inner cylinder and while the cover 9 is still open the reservoir is filled with water which also fills the cylinders. On closure of the cover, a fall in the water level in the reservoir produces a like fall in the outer cylinder, the water flowing through the holes 4. This water being lighter than the solution in the inner cylinder 3, rises therein displacing an equal quantity of the solution through the pipe 5 into the cup 6 and reservoir. The liquid capacity of the annulus between the cylinders may be reduced by arranging rods 8 therein. The cup 6 checks diffusion of the solution into the reservoir when the level of the water therein is steady.

Abstract: 463,968. Actuation of switches. TISDELL, T. A., RAE, W., and AMAL, Ltd. Oct. 8, 1935, No. 27815. Addition to 442,387. [Class 38 (v)] A switch of the type described in the parent Specification comprises a lock barrel 14 fixed to a knurled operating member 3 and by means of an extension 15 and spring-pressed pin 16 to a sleeve 19 connected to a shaft 21. A disc 25 is splined on the shaft 21 and carries driving pins 26 carrying a contact disc 29 urged by springs 35 against the end of the casing which bears contacts 36 connected in the ignition circuit of a motor vehicle. When a key 49 is withdrawn, the wards 47 of the look engage in a slot 48 in a sleeve 12 fixed by a screw 10 to a sleeve 9 which can slide but not rotate in a casing 6 due to the engagement of screw 10 in a slot 11. If the key 49 is inserted the lock barrel can be turned either by the key or by the member 3 to turn the contact disc 29 from the locked off position into the unlocked off position and finally into the on position. Movement between the last two positions is independent of the key since the wards 47 are then situated in a wide slot 50 in the sleeve 12. The shaft 21 is connected to the inner wire 39 of a Bowden wire connected at its other end to a remotely positioned retractive switch (not shown) controlling the starting motor. This switch is operated by pulling the member 3 to the left thus moving the lock barrel 14, sleeve 19, shaft 21 and sleeve 9 against the action of a spring 42. This can only be done when the shaft 21 has been rotated to the unlocked off position or to the on position as only on these positions are splines on the shaft 21 opposite to segmental enlargements (not shown) of an opening 22 in the casing 6.

Title: Improvements relating to pressure sensitive adhesive labels
IPC: G09F3/10
Filed: 1962-07-19
Abstract: 975,119. Laminates. A. B. KARN. July 19, 1962 [July 19, 1961; June 25, 1962], No. 27818/62. Heading B5N. [Also in Division B8] A label or label stock comprises a sheet 10, Fig. 3, having a surface which can be printed upon, a layer 12 of pressure sensitive adhesive, an inner backing 13 which is stuck to and covers the layer 12 and an outer backing 14 which covers the inner backing 13. At least one portion of the backing 14 is more strongly stuck to the backing 13 than the inner backing is stuck to the layer 12 of adhesive and another portion of the backing 14 is readily releasable from the backing 13 to enable this portion to be gripped for detaching the outer backing 14 and at least a part of the inner backing 13 from the sheet 10. In addition, a priming coat may be interposed between the sheet 10 and adhesive 12, and a coating of adhesive repellant may be provided on the backing 13 in contact with the adhesive 12. The inner backing 13 may be formed with slits 16 along which are strips 17 of adhesive for bonding it to the outer backing 14. On lifting one free end of the backing 14, the backings 13, 14 may be pulled away and removed except for an end portion 13a of the backing 13 held by the fingers, this portion being subsequently removed. Alternatively, the adhesive strips 17 may extend transversely to the slits 16 which may be discontinuous or both backings may be continuous and the relative tearing strengths of the backings 13, 14 being such that the backing 13 is torn along a strip 17 when the backing 14 is pulled away. In further modifications both backings are slit, the slits being offset with respect to each other. The adhesive coating bonding the backings may be in strips which cross to form a grid. In a form of " laid-on " labels, the label strip or stock is cut through the sheet 61, Fig. 10, and pressure-sensitive adhesive layer 63 only, but the inner backing 60 is slit longitudinally and a strip of adhesive 65 along this slit secures it to the outer backing 64. After the matrix has been removed, the outer backing 64 can be peeled off carrying with it half of the inner backing 60 and leaving the labels secured to and projecting from the other half of the inner backing. Labels which are formed and separated merely by knife cuts may be made similarly. The label and backing layers may be of paper, the outer backing having a non-porous coating. The pressure-sensitive adhesive may contain natural or synthetic rubber, and the adhesive between backings may be, e.g. heat set, waxes, synthetic resins or contact adhesive.
