Title: Apparatus for preparing and discharging water having controlled amounts of carbonation
IPC: B67D1/00
Filed: 1962-10-24
Abstract: 998,115. Carbonating water. VENDO CO. Oct. 24, 1962 [May 7, 1962], No. 40207/62. Heading B1C. In a method of and apparatus for preparing water having controlled amounts of carbonation a cylinder 20 has a piston 22 dividing it into chambers 36, 38 ; in the stand-by condition the piston is at the. bottom of the cylinder and chamber 36 is filled with water through check valve 76 and line A. When solenoid valve 362 is opened to admit carbon dioxide from line E to chamber 38 the piston 22 rises expelling water from chamber 36 through lines AB into chamber 38 ; the water is forced as a fine spray into the carbon dioxide line before entering the chamber, see Figs. 4 and 5 (not shown). When the piston reaches the (adjustable) limit of its travel an abutment unseats valve 54 venting chamber 38 to atmosphere ; the pressure drop enables its spring to open valve 112 discharging the carbonated water from chamber 38. If water of a lower degree of carburation is required the solenoid valve 162 is opened by-passing a controlled amount of water via lines C and D, the adjustable valve 182 and check valve 188 to the chamber 38 without spraying it into the carbon dioxide line (see Figs. 16-20, not shown). Plain water may be obtained by keeping valve 362 closed and opening valve 162 ; the piston then stops at the bottom of the cylinder and water flows through lines B and C and the check valve 136 direct to discharge line F.

Title: Improvements in or relating to the production of sheathed formed elements
Inventor: GAUTHRON MAURICE
IPC: B21C37/15
Filed: 1958-12-19
Abstract: 887,797. Making sheathed articles; drawing; tube expanding. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 19, 1958 [Dec. 19, 1957], No. 41054/57. Classes 83 (2) and 83 (4). A process of sheathing a pre-formed element consists in inserting the element into a container, evacuating the container and heating it simultaneously with or prior to reducing its internal and external diameters by passing through a die. A nuclear fuel element 52, Figs. 2, 3, is inserted in a cylindrical container 34 having a chamfered closed end and an open end which is positioned in a coupling muff 58 located on a ram 30. The muff 58 and the interior of the container 34 are evacuated through a pipe 37 leading from a central chamber 59 and argon from an inlet 39 is directed into outer chambers 60, 61. The ram 30 guided on shafts 29 pushes the sheathed element 52, through two dies 44, 46 in series. The space between the dies 44, 46 is enclosed by a ring 53 to form a gas-tight chamber, the exit from which is sealed by a plug 49. The dies 44, 46 are electrically insulated from each other and are maintained coaxial by three rods 56. A conical die holder 47 enables a second die 46 of any desired diameter to be fitted. After the element enters the die 44 the space between the dies is evacuated through a passage 36 and argon is then fed through inlets 40, 41. A current of 2,000-3,000 amps at 2 volts is passed between the dies through the container 34 as sheathing proceeds. Before the element 52 is inserted in the container 34 material such as sodium may be inserted to form a film between the element and the container as the sheathing process proceeds. In a modification, the apparatus is used to sheath internally and externally a tube 68, Fig. 4. The tube 68, together with sheathings 69, 70 is pushed by the ram which may be fluid pressure or screw actuated between a die 66 and a tube expander 67 which may be water-cooled. Heating current is passed between the die 66 and the tube expander 67.

Title: Process for dyeing or printing fibrous materials of aromatic polyesters
IPC: C09B1/60
Filed: 1961-11-23
Abstract: Fibrous materials of aromatic polyesters are dyed and printed using as dyestuff an anthraquinone free from solubilising acid groups and containing at most four fused rings and also an arylsulphonylamino group preferably attached in the a -position. Advantageously the dyestuffs also contain at least one auxochrome which may be a hydroxyl, amino, alkoxy or alkylmercapto group or a halogen atom or it may be a member of a fused heterocyclic ring. The arylsulphonyl residue may by substituted with, for example, halogen atoms or hydroxyl, lower alkoxy or alkyl groups.  Of special interest are dyes of the formula <FORM:0917258/IV (b)/1> in which X is an amino or hydroxyl group, Y is a hydrogen or halogen atom or an alkoxy or alkylmercapto group and Z is a hydrogen or halogen atom or a hydroxyl, alkoxy or alkyl group. The alkyl and alkoxy groups preferably have 1-6 C atoms and may be substituted with hydroxy or alkoxy groups. Mixtures of the above dyes often exhibit better affinity than the single dyes.  They may be prepared by reacting the appropriate amino-compound with an aryl-sulphochloride or by condensing an a -halogen-anthraquinone with an aryl-sulphonamide. Specified dyes are: 1-paratoluenesulphonylaminoanthraquinone, 1-chloro- 4-paratoluenesulphonylaminoanthraquinone, 1-hydroxy- 4-paratoluenesulphonylaminoanthraquinone, 1:4-dihydroxy- 5-paratoluenesulphonylaminoanthraquinone, 1-methoxy- 4-para-toluenesulphonylaminoanthraquinone, 1-amino-4-para-toluenesulphonylaminoanthraquinone, 1-methylamino- 4-benzene sulphonylaminoanthraquinone, 1- phenylamino-4- benzenesulphonylaminoanthraquinone, 1-amino- 2-methoxy- 4-para-toluene sulphonyl amino anthraquinone, 1-amino-2-methoxy-4-b -naphthalene sulphonylaminoanthraquinone, 1-amino- 2-(b -hydroxyethoxy)- 4-paratoluene sulphonylaminoanthraquinone, 1-amino-2-(b -methoxyethoxy)-4-benzene sulphonyl amino anthraquinone, 1-amino- 2-bromo- 4-benzene sulphonylaminoanthraquinone and 4- or 5-benzenesulphonylamino-1:9-isothiazoleanthrone.  Dyeing may be effected with a fine dispersion of the dyestuff in the presence of a dispersing agent, e.g. N-benzylm -heptadecylbenzimidazole, and a carrier, e.g. ortho-hydroxydiphenyl, or without a carrier at superatmospheric pressure and a temperature of 120 DEG C., advantageously from a bath made weakly acid with acetic acid. Alternatively the material may be impregnated below 60 DEG C. with a liquor containing in addition, urea and an alginate and thereafter thermofixing at 180-210 DEG C. Mixed fabrics of polyester and cotton may be dyed or printed with the present dyestuffs together with a vat or reactive dyestuff in p  the same bath.  Examples of dyeing and printing materials of polyethylene terephthalate and its blends with cotton are given. Specification 750,969 is referred to.

Abstract: 1,273,805. Computers. INSTITUT KIBERNETIKI AKADEMII NAUK UKRAINKOI SSR. 26 Aug., 1969, No. 42465/69. Heading G4A. In a computer capable of the structural interpretation of an input algorithmic language, an input/outputdevice 1 for entering the programme in terms of an input algorithmic language and for information retrieval is connected to storage 2 which is coupled to a table arithmetic unit 3 and to a data analyser 14 specifying character features pertaining to certain classes of an input language character set, and an interpretation control unit 8 is both micro-programmed and multi-level and incorporates a pair of independent reversible location counters in each level for ensuring micro-programme control in the corresponding level. In the interpretation control unit 8, three microprogramme matrices 23, 24, 25 are addressed by respective pairs of the counters 26, 27; 28, 29; 30, 31. Each matrix can zero the counters of the lower matrices (if any), control its own counters, control the higher matrices (if any), and control the rest of the computer. The data analyser 14 supplies micro-programme branch control signals to the matrices over paths 44. An encoder 7 is connected to storage 2, control unit 8 and registers 4, 5,..., 6 and can increment/ decrement the latter by 1. The registers 4, 5 ... 6 are used for address and character storage and for forming stacks in the storage 2. The programme is thus executed interpretively with direct conversion of the input language into microoperation control signals. However, to save  storage space, preprocessing is done under microprogramme control, involving the establishment of various auxiliary tables in storage 2. If storage 2 becomes full during the interpretive execution, overflow detector 41 starts a data compaction (garbage collection) routine of the control unit 8 by signalling the counters 26, 27 via lines 43. The arithmetic unit 3 uses storage 2 for registers, and includes addition, subtraction, multiplication and character conversion tables.
