Title: Maintenance of stress in a mud riser - telescopic riser gives hydraulic pressure indication of stress increasing or decreasing force exerted accordingly
Inventor: DAGET PATRICK
IPC: E21B47/00
Filed: 1975-06-18
Abstract: A device for measuring tension and keeping elastic stability in a mud riser is described. The riser is in two parts, joined telescopically and hydraulically. The tension is arrived at by measuring the pressure in the hydraulic circuit feeding the assembly. The tension controller is a jack with its upper chamber joined to an oil reservoir under pressure. The lower chamber is joined to control. The control shuts off the connection to the air reservoir. When the tension exceeds the chosen value the control moves the jack down, lessening the effort of the cable. If the tension is insufficient, the reverse type of action takes place.

Title: Expanding mandrel for toothed workpieces - has needles around tapered portion to lock in gaps between teeth
IPC: B23B31/02
Filed: 1975-07-18
Abstract: An expanding mandrel to grip e.g. toothed surfaces, is expanded by axially displacing a conical piston (1) inside a tapered cylindrical sleeve (2). A series of round needles (13) around the sleeve engage the workpiece (P) indentations. The needles (13) are regularly spaced around the sleeve (2) and align with their axes parallel to the sleeve and piston axes, so that a needle locks between the inclined faces between two teeth to lock the workpiece in place with complete absence of circumferential play. The conical piston may have a flange (12) secured by bolts (14) to a bell shaped housing (3). This also contains an enlarged sleeve head (22) carrying the needles (13). The piston (11) is displaced in the sleeve (2) by a screw jack (4) and push rod (5).

Title: Telescopic panel e.g. window blind - has overlapping inverted L:section blades with horizontal flange of reducing width on lower blades, suspended on cords
IPC: E06B3/92
Filed: 1975-10-16
Abstract: The telescopic panel may be deployed as a window blind or screen, and comprises several identical parallel blades of 'L' section. One flange of each 'L' section lies in the major screen plane; and each blade slides telescopically into its neighbour to obtain blind retraction. In the case of a window blind the blades (1) may be of inverted 'L' section with the horizontal flanges decreasing in width in a linear relationship from top to bottom blade. The blades thus slide into one another under purely vertical displacements, and the horizontally laminated face of the extended blind inclines from top to bottom towards the ribbed face. The lateral blind edges may run in channels (6); a pulley (5)-cable (4) winding system be deployed; a rectangular hollow section (3) lead the descent; round rails (2) form vertical guides; and thread (7) with stops form blade spacing.

Title: Coatings for ingot moulds and bases - using a machine with two tanks and sprays for separate coating of base and wall
IPC: B05B13/06
Filed: 1976-02-06
Abstract: The coating is applied by (a) spraying the base-plate and the lower part of the mould wall with one substance or mixt. followed by (b) spraying the remainder of the mould wall with a second substance or mixt. The device pref. consists of two sprays moulted on one head and arranged so that after the head is lowered into the mould, one spray with an angle of 30-90 degrees is used for stage (a) and the head is then raised while the second spray, operating over 360 degrees at right-angles to the mould axis, carries out stage (b). Coating (b) is designed to improve the surface of the ingots and pref. consists of a mixt. of molasses with a synthetic product contg. asphaltene. The treatment thus proects the base-plate with a ceramic coating and coats the mould wall in one operation.

Title: Urinary metabolite determn. using a paper strip - contg. activated ion exchange resin or silica gel, washing to remove unwanted metabolites, elution and colourimetric determn.
Inventor: GAUNTLEY PHILIPPE
IPC: A61B10/00
Filed: 1976-04-29
Abstract: Process and appts. removal and fixation of urinary metabolites on an immobilising support, which is easily transportable to an analysis centre, comprises (a)-contacting the support with the urine so as to remove a sample and fix the desired metabolite onto the support accompanied by certain unwanted metabolites; (b) transporting the support to the analysis centre; (c) eliminating the unwanted metabolites (those which would interfere with the subsequent determination of the desired metabolite) from the support; (d) eluting the desired metabolite and determining its concn. The support is paper which contains a material which is readily activated before use. The result of the metabolite determination may be expressed w.r.t. the result of the determn. of a metabolite in which the excretion is constant over period of time. Used for determn. of urinary metabolites such as delta-amino-levulinic acid or ALA (metabolite characteristic of lead poisoning), trichloroacetic acid and trichloroethylene intoxication) and creatinine. The amt. of urine removed depends on the paper used and for a given size of paper of constant quality, the amt. is known with good accuracy. The expression of the result w.r.t. the result of the determn. of a metabolite whose excretion is constant avoids false results due to variation on the amt. of urine removed and the different dilution of the urine.

Title: Carbon source for glutamic acid or lysine fermentation - prepd. from a neutral hydrolysate of molasses contg. glucose and fructose
IPC: C12P13/14
Filed: 1976-04-29
Abstract: The known prodn. of glutamic acid (I) or lysine (II) by fermentation of Brevibacterium, Corynbacterium, Micrococcus, or Microbacterium spp. is improved as follows (a) a neutral hydrolysate of molasses contg. glucose and fructose at 10 degrees is mixed with Ca(OH)2 to ppte. a fructose addn. product, (b) the remaining mother liq. is neutralised to eliminate Ca++ and the remaining liq. is used as the C source for the above fermentation. Method not only provides a very inexpensive source of fructose (a sweetening agent eg for diabetics but also does not alter the yields of (I) or (II) obtd. in the known fermentation above. In an example an invert sugar soln. at 0 degree was treated with 30% Ca(OH)2 (1 mole equiv). Sepd. adduct in H2O was neutralised with H2SO4 to give a soln. contg. fructose (50% yield) and only a trace of glucose.

Title: Electrical gas laser exciter, with non-stationary inversion - earth potential storage and forming conductors of layered foil
IPC: H01S3/0973
Filed: 1976-07-08
Abstract: A device for exciting gas discharge lasers with non-stationary inversion and transverse unloading configuration is based on band conducting principles. The band conductors constituting the storage and forming conductors of the electrical exciter circuit, have a circular arc chamber which does not detract from their stability under tension. The conductors are assembled in a pack in such a way that the gaps form a concentric opening in which the high tension switch is connected geometrically coaxially to the tension conductors. Overcomes the difficiencies of expensive coaxial cables with their liability to breakdown, the parasitic inductivity of condensers increasing the impedance of forming conductors, and band conductors tending to increase the inductivity of the total circuit, and extend the loading time of the forming conductor.

Title: Ridging free deep-drawing ferritic stainless steel sheet prodn. - using warm rolling and continuous annealing steps
IPC: C21D8/04
Filed: 1976-12-29
Abstract: A ridging-free ferritic stainless steel, for deep drawing applications, is mfd. by hot rolling, coiling at 450-750 degrees C warm rolling at 450-700 degrees C with >=15% redn. in a mill installed separately from the hot rolling mill train, continuous annealing cold rolling and final annealing. During warm rolling, ferrite deforms in preference to austenite and shear of deformation bands break up the elongated grains formed by hot rolling. A weakly directional texture, which is retained after cold rolling and annealing, is formed to reduce the planar anisotropy of T values of the product. Warm rolling also allows a short time continuous anneal. to be used. The process can be carried out in the same rolling mill as used for low carbon steel sheet but modifie dby an off-line warm rolling mill. The method is esp. useful in preventing ridging in Ti-stabilised extra low carbon ferritic stainless steels caused by development of left brace 100 right brace 011 > and left brace 554 right brace 255 > textures.
