Title: Pressure generating apparatus for hydraulic systems
IPC: F15B11/02
Filed: 1944-11-21
Abstract: 601,021. Hydraulic intensifiers. PAGE, H. E. Nov. 21, 1944, No. 23143. Convention date, Jan. 11. [Class 69 (ii)] Hydraulic pressure is supplied at three values successively from the intensifier 5 to a remote hydraulic jack. The two-step piston 14 is first moved outwardly by the spring 20 to bring the remote jack ram into contact with the work by fluid from the cylinder 18 and pipes 92, 100a. Next the hand pump 23 is operated to pass liquid from the reservoir R to the small cylinder 16. When the pressure in the cylinder 16 reaches a predetermined value, the valve 76 opens and fluid pressure acts in the cylinder 17 also thus increasing the pressure in the cylinder 18. To allow retraction of the remote jack ram, valve cam 42 is turned, opening valves to allow fluid flow to the reservoirs. If power retraction is necessary, valve 90 is also repositioned.

Abstract: 695,002. Cutting moving clay &c. columns. STEENBRUGGE & CO., Ltd., M. Nov. 28, 1951 [Oct. 4, 1951], No. 23144/51. Class 87 (ii). A clay column is cut by movement in either direction of a cutter which moves forward with the column and releases an end stop for the column. The clay column (not shown) moves over a lubricated roller 1 and between rollers 2 and 4 onto the table 8 of a horizontally movable carriage 35 where it abuts a stop plate 9. The carriage moves forward some distance with the clay column which is cut by movement in either direction of a wire cutter 10 pivoted to a shaft 13 on the carriage 35. Depending upon the direction of movement of the cutter, one of a pair of arms 20, 21 fixed to the shaft 13 strikes one of a pair of rollers 26, 34 mounted on the ends of a vertical arm 27 welded to a square bar 28. To allow the arms 20, 21 to pass the rollers 26, 34 in the reverse direction they are furnished with pivoted spring-pressed fingers 22, 23. The bar 28 normally engages an arm 30 fixed to a shaft 31 which carries the stop 9. When it is displaced longitudinally against spring 29 by one of the arms 20, 21 the shaft 31 is able to rotate under the influence of an adjustable weight 33 and the stop 9 falls to the horizontal position. The cut-off portion of clay may then be moved away from the movable carriage. The carriage 35 returns under the influence of a spring 42. The tension of the wire cutter 10 can be adjusted by means of a ratchet wheel 18.

Title: Improvements in or relating to fuels for nuclear reactors
Inventor: MURRAY PETER
IPC: G21C3/64
Filed: 1963-06-11
Abstract: 1,042,008. Fuel material. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. May 15, 1964 [June 11, 1963]. No. 23210/63. Heading G6C. A fuel material for a nuclear reactor comprises a dispersion of mixed zirconium and plutonium dioxides in an alloy of zirconium forming a matrix material. Suitable alloys for use in a pressurized water environment and which have a neutron capture cross-section not appreciably higher than zirconium itself are those known as "Zircaloys" " which have a composition by weight of 0À25-2À5% tin, 0-0À25% iron, 0-0À16% chromium and 0- 0-08% nickel, the rest being zirconium except for incidental impurities. The zirconium dioxide renders the plutonium dioxide thermodynamically stable in the presence of the zirconium metal in the alloy and for this purpose the molar ratio (ZrO2 : PuO2) should normally be greater than one. A mixed oxide content of up to 40 vol. per cent is possible and plutonium concentrations of up to 1 gm./c.c. may thereby be obtained in the cermet. This may be more than is needed, in which case dilution of the plutonium oxide with a fertile metal oxide, e.g. Th<232>O2 or U<238>O2, is possible. A fuel element is manufactured by preparing spheroids of the mixed oxides, distributing the spheroids uniformly in a matrix of the zirconium alloy which is pressed to form a cermet compact and fabricating the fuel element from the cermet compact by cladding with a suitable metal, preferably the zirconium alloy of the matrix. In an example, the cermet compact was placed between sheets of "Zircaloy" and rolled to form a plate-type element using a picture-frame rolling technique. Alternatively, the fabrication may be effected by swaging to give rods or by a pressing procedure, e.g. hot isostatic pressing, to give rods, plates or complex shapes as desired.

Title: Improvements in apparatus for grading eggs, fruit or the like
IPC: B07C5/22
Filed: 1929-07-29
Abstract: 336,328. Cowan, I. M. July 29, 1929. Separating or sorting by weighing.-In grading- apparatus for eggs, fruit and other articles, of the kind in which the articles pass along an inclined track having one or more tiltable sections adapted to deposit articles exceeding a certain weight onto a lower track leading to a receptacle, means are provided to prevent the passage of subsequent articles until the leading article has been graded. As shown, eggs roll down an inclined track 2, Fig. 2, having a number of tilt'able sections 3 each mounted on a counterbalanced lever 4 fulcrummed on bearings 7. Under the load of an egg exceeding a certain weight, the section tilts and deposits the egg onto a rockable track 15 that in turn deposits the egg onto a counterbalanced track 20, connected by a stationary track 21 to a receptacle 32, Fig. 3. During the period that the section 3 is displaced, the passage of eggs along the track 2 is prevented by gravity-actuated stops 60 normally disabled by extensions 11 of the lever 4. Upon the return of the section, the passage of eggs is still prevented by a stop 27 connected to the track 20 in such a manner as to be operative while that track is depressed under the weight of an egg. The downward tilting of the section is accelerated, and the upward tilting thereof retarded, by a ball 9 freely movable within a tube 10 carried by the lever 4. The eggs are marked during their passage along the track 21 by a flexibly-mounted printing-element 36, Fig. 3. Inking-means for the printing-element comprise an arm 38 carrying pads 37 and given half a revolution by a clockwork mechanism 39, released upon the passing of each egg. Eggs are prevented from leaving the track 21, in the absence of a receptacle 32, by a spring-urged stop 28 normally held inoperative by the abutment of the tray against an extension 30, thereof.

Title: Improvements in and relating to radiography scanning systems
IPC: G02B27/02
Filed: 1960-07-04
Abstract: 881,464. Radiography scanning systems. KROP, H. July 4, 1960, No. 23353/60. Class 98(1). X-ray pictures of an object are rendered visible by scanning the object with an X-ray beam which is then picked up by a detector; the scanning is effected by two cylinders rotatable about the X-ray source, the cylinders having slits which between them mask out the X-ray beam except for a part which is caused to scan the object. Fig. 1 shows in developed form two concentric cylinders. The outer one has twelve slits spaced round its circumference, parallel to the axis of rotation, and this rotates at 250 r.p.m. to give a picture frequency of 50/sec. The inner cylinder has twenty-five slits which are inclined to the axis of rotation, as 'shown in dotted lines, and this rotates at 75,000 r.p.m. to give a 625-line scan. This arrangement scans a trapezoidal picture area. For a square picture area, the two cylinders, and the slits therein, can be arranged in mutually perpendicular fashion, as in Fig. 3. The output of the detector can be coupled to a cathode ray tube so that a visible picture is obtained on the screen.

Title: Anaesthetic composition
IPC: A61K31/24
Filed: 1952-09-17
Abstract: The dialkylaminoethyl esters of 4-amino-2-hydroxy-benzoic acid in which each alkyl group contains not more than 10 C atoms, are prepared by reacting 4-nitrosalicylic acid in an organic solvent such as methylene chloride, benzene or carbon tetrachloride with thionyl chloride to produce nitrosalicylic acid chloride, which is reacted with the desired aminoethanol to produce the dialkyl aminoethyl ester of 4-nitro-salicylic acid.  This is then reduced with hydrogen in the presence of a hydrogenation catalyst such as the noble metals.  The esters produced are anaesthetics (see Group VI).ALSO:An anaesthetic composition comprises a mixture of a dialkyaminoethyl ester of 4 - amino - 2 - hydroxy - benzoic acid (A) and a dialkylaminoethyl ester of a N - monosubstituted 4 - amino - 2 - hydroxy - benzoic acid (B), each of the alkyl groups in both esters containing not more than 10 carbon atoms.  The mixture consists of 80 - 99 per cent A and 1 to 20 per cent B.  It is preferred that the N - alkyl substituent of B contains not more than 4 carbon atoms, e.g. n - butyl.  Specified are the dimethylaminoethyl and the diethylaminoethyl esters of 4 - amino - 2 - hydroxy - benzoic acid and 4 - n - butylamino - 2 - hydroxy benzoic acid.  Pharmaceutical and veterinary preparations, are obtained by dissolving the anaesthetic mixture in a solvent suitable for injection into the human or animal body, e.g. water or physiological sodium chloride solution.  Vasoconstrictors such as adrenaline, noradrenaline and l - o - dihydroxy - phenylpropanolamine hydrochloride may be added.  The dialkylaminoethyl esters of the N - substituted 4 - amino - 2 - hydroxybenzoic acid are produced according to Specifications 736,960 and 760,003 [both in Group IV(b)].  Substance A is produced by reacting 4-nitro salicylic acid with thionyl chloride (see Group IV(b)).
Patent GB-234453-A (GB)
Abstract: 234,453. Short, T. A. May 24, 1924, [Convention date]. Separating by gravity; filters with loose filtering-materials.-The presence of one liquid in another of different specific gravity flowing through a tank, for example of oil in feed water for boilers, is indicated by a signal operated by a float which sinks when the lighter liquid accumulates on the surface. The device may be associated with a filter which removes oil from the water. Water supplied to a tank 1 by a pipe 2 is directed upward into a compartment 7 by a baffle 29 and flows over dividing plates 5, 6 into compartments 15, 16 containing loofah sponges 17. The spaces below the sponges are connected by pipes 28, and the water freed from oil is discharged through a pipe 3. When oil accumulates in the compartment 7 the float 10 falls and a lever 19 makes contact 21, 22 to close a circuit through a battery 24 and lamp 26 or other alarm signal. Oil collecting on the water may be drawn off through a pipe.

Title: Method of dyeing
IPC: D06P5/00
Filed: 1945-09-13
Abstract: Textile materials are dyed by uniformly applying an aqueous solution of the dye to the materials and then subjecting them, while still wet with the dye solution, to an atmosphere of high relative humidity, e.g. 85 to 100 per cent, at a temperature appropriate to the dye solution <PICT:0606131/IV (c)/1> used.  The dye solution is preferably applied by a continuous progressive immersion of the material in the dye solution or by continuous application of the dye solution to the surface of the material using, for example, a rotary cylindrical surface of mohair, having projecting nap fibres adapted to be wetted by the solution.  In the Figure, the yarn is drawn over the cylinder 14, the surface of which is covered with mohair and immersed in the dye solution, and then passed through the guide 3 and tensioning device 6 and wound up on the empty roll 7.  As the amount of yarn on the roll and the surface speed increases, the guide bar 9 which rests upon the surface of the yarn moves towards the new position 91 and, by means of the lever 10 and rod 13, moves the guide 3 towards the new position 31.  The length of contact of the yarn with the applicator cylinder 14 is thereby increased to compensate for an increase in the speed of the yarn in the course of the dyeing. The full package 8 is removed and placed in a humidity chamber where it is heated, to promote the dyeing of the yarn, in an atmosphere of high humidity without permitting any rapid or substantial loss of solvent or change in concentration or distribution of the dye solution.  Heating is effected, for example, by introducing steam. Tables are given showing the effect of temperature, time and humidity on dyeings with Brilliant Benzo Blue to BA, Chloramine Brilliant Flavine S, Fastusol Red 8 BLN.  Fastusol Green LBBE and Chloramine Carbon Black SN.  The process may be applied to the dyeing of wool, cotton, cellulose acetate or nylon.  Specification 590,793, [Group VIII], is referred to.

Title: Improvements relating to apparatus for controlling the movement of a beam in search and follow operations
IPC: G06V30/144
Filed: 1965-06-03
Abstract: 1,078,339. Automatic character reading. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 3, 1965 [June 4, 1964], No. 23647/65. Heading G4R. In apparatus for searching for and following the outline of a pattern, e.g. a character, there are means for causing a beam to search for the pattern and means responsive to the arrival of the beam at the pattern to switch the apparatus from the search mode to a follow mode, and to switch it back to search mode when the following operation is complete. The search mode consists of a series of horizontal strokes 17 vertically. As soon as the pattern is encountered the follow mode begins as described in Specification 1,072,530. The point where the beam meets the pattern is termed the "A box," Fig. 2 (not shown), and the location is stored. A second location, the " B box," is also stored, this being a predetermined vertical and horizontal distance away from the A box. These stored locations are used as references to determine when the beam has completed the following of the outline of the pattern, by reentering the A box and then the B box. During the following operation the maximum vertical excursions of the beam are stored and the maximum horizontal excursion to the righthand edge of the pattern. These values are used to position the beam first to the right and in the vertical centre of the pattern ready for searching for the next pattern. Each of the boxes, A and B, is defined by four threshold devices connected to the horizontal and vertical deflection voltages. Each group of four threshold devices is connected to an And gate. When the beam is in the A box the corresponding And gate gives a signal which sets a flip-flop giving a fifth input to the And gate of the B box so that when the beam arrives in the B box the gate responds indicating that the following operation is complete.
