Title: Method of retrieving an underwater drilling wellhead assembly from the floor of a body of water
IPC: E21B29/12
Filed: 1965-10-04
Abstract: 1,122,004. Wells &c. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 4 Oct., 1965 [5 Oct., 1964], No. 42022/ 65. Heading E1F. An underwater drilling wellhead assembly having pipes 22, 50 penetrating the bed 13, is freed from the bed to permit raising to the drilling vessel 11 by severing the pipe 50 in the bed and by applying tension to the pipe 52 to break a joint therein. The pipe 50 is severed by a cutter 55. Hydraulic fluid is supplied to the well by a pipe 57 carrying the cutter, and rams 60 of a blow out preventer 28 or the bag of a blow out preventer (29) (not shown) are or is closed about the pipe 57 so that hydraulic pressure shears pin in a collar 51 on the pipe 22 to free an upper part 22a. The assembly is raised by hoisting the marine conductor 32, lengths of the conductor being removed as necessary. An alternative method of shearing the pins comprises closing the upper blind rams (not shown) of the preventer after removing the pipe 57, and supplying pressure fluid to the interior of the preventer. If a coupling (31) (Fig. 1, not shown) joining the marine conductor to a flexible joint (30) on top of the blow out preventer (29) above the preventer (28) cannot take tension, a string having an enlargement engaged by the rams 60 of the preventer 28 is used to hoist the assembly.

Title: Improvements in or relating to sealed closure means for apertures
Inventor: BARRETT NORMAN THOMAS
IPC: F16J13/02
Filed: 1961-11-24
Abstract: 977,319. Pressure doors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 12, 1962 [Nov. 24, 1961], No. 42117/61. Heading F2P. A sealable closure for an aperture comprises a hinged door which is resiliently sealed around the aperture when fully closed and which is opened by, firstly, disengaging the seal, secondly, displacing the door transversely relative to the aperture and lastly, pivoting to remove the door from the aperture. Closing is effected by a reversal of this procedure. The door 2 is one of a pair which form an airlock in the access chamber 1 to the containment pressure vessel for a nuclear reactor. It carries 0-ring seals 6 on a flange 5 to engage a flange 7 around the chamber aperture. The door is supported on a shaft 3 which is unrotatably housed in one end of a frame 4 which is pivoted at its other end to the chamber wall. The shaft 3 comprises pins 8 and 9 interconnected by a screwthread at 10 and has extensions 12 at either end slidably penetrating guide bushes 13 on the door. A composite sleeve 19, 20 carrying a spur gear 17 is located on the shaft 3 between bushes 15 and engages internally a screw on the pin 8. Operation of a hand wheel 26 turns the sleeve 19 by way of gears 24, 23, 21, and causes the door to be lifted relative to the frame 4 until it is clear of the channel 53 at the foot of the aperture. The door is secured closed by four series 32 of shoot bolt mechanisms 33 each comprising a bolt 34 which is slid in a guide 35 by operation of toggle levers 36 connected to a double-acting hydraulic ram 37. Each bolt has an inclined face 39 which bears between rollers 40 on the door; a lip 38 on the bolt ensuring that the seals 6 are disengaged before the door moves transversely. The rams 37 are operated by a hydraulic pipe-line which includes a pump 41 manually operated by a hand wheel 42. Each of hand wheels 26 and 42 are provided on both sides of the door. A tappet operated by-pass valve 46 is associated with one ram 37a and ensures that the other bolts 34 are not pushed home until that at 37a is engaged. A similar valve 47 ensures that the shoot bolts of the door concerned cannot be withdrawn unless those on the door at the other end of the access chamber are fully engaged. A third valve 48 ensures that the rams 37 are not operated until the door has been lowered into the recess 53. Cam-shaped locating hooks and guard strips on the door (Fig. 4, not shown) engage with rollers on the chamber wall to guide the door during raising and lowering.

A control device for a fluid pressure braking system including a source 12 of fluid pressure and brake actuating cylinders 10 has in combination a slide valve 16 to connect the cylinders 10 selectively to the pressure source or to a drain, a valve operating member and a spring 32 between the valve spool 21 and the operating member which produces a load in the spring urging the valve to connect the pressure source to the cylinders and a deceleration responsive member such as a suspended weight 44 which exerts a force, depending on the deceleration rate of the vehicle, to oppose the spring. A pump 13 draws fluid from a low pressure reservoir 14 and supplies it to the accumulator 12.
Patent GB-1076649-A (GB)
Title: Process for treating wool
IPC: D06M15/59
Filed: 1964-10-19
Abstract: Wool is shrinkproofed by contacting it with one solution selected from a solution containing at least one diamine and at least one polyamine containing more than two amino groups per molecule and a solution containing a polyacid polyhalide containing at least two acid halide groups per molecule, the solutions being mutually immiscible, and then contacting it with the other of the solutions. A polymer formed at the interface of the two solutions is grafted onto the wool.  The wool is preferably treated first with an aqueous solution containing the diamine and polyamine and if desired a wetting agent, e.g. a polyoxyalkylated alkyl phenol, and sufficient basic material, e.g. sodium, calcium or potassium carbonate, to neutralize the acidic constituents formed during the interfacial polymerization reaction, and then with a solution of the polyacid polyhalide in a water immiscible organic solvent e.g. hexane, heptane, octane, Stoddard's solvent, naphtha, benzene, toluene, m-xylene, o-xylene, p-xylene, ethyl benzene, cyclopentane, methylcyclopentane, carbon tetrachloride perchloroethylene and dichlorobenzene.  Numerous examples of suitable diamines, polyamines and polyacid polyhalides are given.  The process may be carried out at 0 DEG  - 80 DEG C. as a batch or continuous process excess solution being removed after the application of the first solution prior to application of the second.

Title: Improvements in or relating to Tension Spring Units
Inventor: GORSKI WOJCEICH
IPC: F16F1/02
Filed: 1967-09-23
Abstract: 1,188,138. Selective printing. INTERNATIONAL COMPUTERS Ltd. 14 Aug., 1968 [23 Sept., 1967], No. 43391/67. Heading B6F. [Also in Division F2] A spring unit for use in a sector-type printer includes a spring element in the form of a bent strip which comprises the straight sections 9, 10, 11 and the curved sections 12, 13 and which is such that in the unstressed element sections 9 and 10 are parallel to each other and are each in contact with another section of the element. The unit also includes relatively movable members 1, 2 so connected to the element that, on moving the members apart the spring element is extended and/or rotated. If the spring element is initially unstressed, such movement of the members will at first merely rotate and, after substantial deflection, will both extend and further rotate it; if, by suitable choice of the minimum separation of the members 1, 2 (e.g. by appropriately dimensioning the projection 4), the element is initially substantially stressed, then the only deformation of the element in use is of simultaneous extension and rotation. Fig. 2 (not shown), indicates that the former arrangement provides a spring rate which is initially positive but subsequently negative whereas the latter arrangement provides a wholly negative spring rate, the restoring force reducing as displacement increases. The members 1 and 2 may constitute respectively the scanner plate and bail bar of a sector-type printer as in Specification 1,187,621. The reduction of spring force with increasing displacement of the scanner plate with respect to the bail bar prevents overloading of the latter, particularly in the case where a plurality of scanner plates are operated by a common bail bar.

[Also in Group VIII] A method of making perforated rolls comprises assembling a plurality of metallic (e.g. aluminium) washers 18, 23, Fig. 6, and a metal (e.g. steel) wire 20 on a shaft 11 so as to form a laminated roll in which the wire is sandwiched between alternate washers, and selectively removing parts of the surface of the roll so as to expose a circumferential array of pins 31, Fig. 8, projecing radially from the roll. The washers 23, before assembly, are machined with notches 21, 22, Fig. 3, and wound with the wire 20 which encircles the washers and engages the notches. The wound washers are then coated by being immersed in a bath of resinous material. The washers 18 are plain. After assembly, the roll has applied thereto a grinding wheel 28 which removes the notches 21 and that portion of the wire disposed therein. The roll is then immersed in an etching bath 35 which selectively removes a circumferential margin of the roll so as to expose the pins 31. The resinous material 32 between the pins is removed, e.g. by brushing.

Title: A forced-flow, once-through boiler and turbine installation
IPC: F01K3/22
Filed: 1960-12-19
Abstract: 929,006. Steam turbine plant. SIEMENSSCHUCKERTWERKE A.G. Dec. 19, 1960 [Dec. 18, 1959], No. 43629/60. Addition to 889,076. Class 110 (3). This invention relates to a power plant as described and claimed in the parent Specification, in which a forced flow, once through boiler having a reheater supplies a turbine having at least a high-pressure stage and a low pressure stage, there being a water-containing vessel connected to the outlet of the highpressure turbine such that some of the steam passes into and through the water in the vessel and gives up some of its heat, this steam and the additional steam generated in the vessel being conveyed through the reheater to the low-pressure turbine. According to the invention, the steam supply and discharge pipes of the water-containing vessel are interconnected by a pipe provided with a valve controlled by the temperature in the steam piping between the reheater and the lowpressure stage of the turbine. A turbine comprises a high-pressure stage 1 and a lowpressure stage 2 connected to a generator 3. The steam from the low-pressure stage 2 is condensed in a condenser 4 and the condensate delivered by a pump 5 through a pre-heating installation 6 to a feed water container 7. A further pump 8 discharges through highpressure bled steam feed-water heaters 17, 18 to a water-containing vessel 9. The liquid from the vessel 9 is delivered by a pump 10 to a boiler 11. The steam from the stage 2 passing through the water chamber of the vessel 9 gives up its superheat and produces additional steam. The newly produced steam and cooled steam flows through the reheater 15 to the lowpressure turbine stage 2. The water-containing vessel 9 is provided with a by-pass 19 containing a valve 20 controlled by the temperature in the steam pipe between the reheater and the lowpressure turbine stages. The valve 20 closes as the temperature increases and vice versa. An additional valve 23, controlled in the opposite direction to the valve 20, may be provided in the outlet from the vessel 9. A pipe connecting the line steam pipe with the intermediate pressure pipe 13 and having a reducing valve 16, may be provided to provide further control of the temperature of the steam in the intermediate section. Specification 920,849 also is referred to.

Abstract: The invention comprises compounds of the formulae <FORM:1069078/C2/1> <FORM:1069078/C2/2> where Ar represents an aryl radical which may be substituted by groups that are inert under reaction conditions, A represents a radical, an aliphatic hydrocarbon which may be substituted by groups that are inert under the reaction conditions with the exception that it should only contain one aliphatically bound halogen atom and may be interrupted by oxygen atoms, R1 is a hydrocarbon radical having 1 to 18 carbon atoms, each R represents the same or different unsubstituted or substituted hydrocarbon radical, m and n represent1, x represents one of the numbers 0 or 1, y represents one of the numbers 0 or 1 and x + y represent one of the numbers 0, 1 or 2, and an alkali metal salt of the acid corresponding to the sulphonic ester.  They may be prepared by reacting a compound of the formula <FORM:1069078/C2/3> where R, x and y have the same meaning as before or two of the R groups may be linked together to form a cyclic phosphite, with a compound of the formulae [(R1OSO2)nAr]mAX or [(R1OSO2)nArO]mAX where R1, Ar, A, n and m have the same meaning as before, and X represents halogen, at a temperature within the range from 20 DEG  C. to below the decomposition temperature of the reactants.  The reaction may be carried out in the presence of anhydrous solvents.  Suitable solvents include aliphatic and aromatic hydrocarbons, halogenated hydrocarbons and ethers. The reaction may be carried out at pressures ranging from 0.1 mm/Hg. to 3 atmospheres. The esterified products can be saponified entirely or partially to form the acids from which they are derived and the acids converted into the salts or other derivatives thereof such as acid halides, acid amides or other acid esters.  The products obtained may be used as intermediates in the manufacture of pharmaceutical products, pesticides and products in which the ester group has been transformed into the free acid or the salt thereof, which are water-soluble and may be used for preparing polyesters.  Also they are surface-active, particularly when containing long chain aliphatic residues, and as such are useful as emulsifiers and detergents.  Examples are given for the production of the compounds.
