Abstract: 1,168,945. Lining wells. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 15 March, 1968, No. 12778/68. Heading E1F. A permeable formation, such as a well bore, is treated with a water displacement fluid such as methanol, ethanol, isopropyl alcohol and mixtures thereof and acetone. A spacer fluid may then be injected. Thereafter a mixture of an epoxy compound in an aromatic hydrocarbon solvent, a curing agent in a aromatic/non aromatic hydrocarbon solvent and three promoters, phenol, meta and para cresol in an aromatic/non aromatic solvent is injected and left to set to a hard cross-linked resin. The epoxy compound and curing agent are in specified quantities and polymerise under controlled conditions. The well is now ready for the injection of a drive fluid. The water displacement liquid may contain a surfactant. Silanes may be incorporated in the polymer as coupling agents. The well may be acidised.

In a modification of a joint according to the parent Specification, wherein a terminal wire 4 of a component 1 and a terminal post 3 are secured together in parallel contact by a separate piece of wire 5, the component is located on one side of a base-plate 2 and the terminal post is located on the other side, the wire 4 being passed through a hole in the plate to make the joint. The terminal post may form one leg of a U-shaped link member 6, Fig. 2, each leg being used as a terminal to connect together components 7, 8. Alternatively, Fig. 3, one leg of each of two U-shaped members 11, 12 may be used as a terminal for one of two components, the binding wire 13 used for making the joints also serving to interconnect the members. This arrangement may be modified by making the interconnection with an independent piece of wire 16, Fig. 4, between the legs of the U-members which were unused in Fig. 3. A link-member having more than two limbs may be used to interconnect a plurality of components as shown in Fig. 9, such a link member being formed from a ladder-shaped blank which is cut along its longitudinal axis. Circuit assemblies using the above interconnections are diagrammatically illustrated.

Patent GB-133557-A (GB)
IPC: D04B11/20
Abstract: 133,557. Johnson, F. Jan. 7, 1919. Straight - bar machines. - Patterned effects are produced by the use of two threads per course, either of the threads being brought to the face of the work where required by suitable operation of dividing- sinkers A with notched throats A'. In ordinary working with two threads, the sinkers A, when dividing loops, would bring the lower thread to the face of the work, but if certain sinkers are held back by the action of the pattern-mechanism a short distance from the falling-bar C, as shown in dotted lines, Fig. 1, the upper thread is brought to the face at these points. On the jack sinker bar E, the inner edge of which is notched to act on the jack sinkers B only, are mounted to slide longitudinally one or more bars F for acting on the dividing sinkers A. The inner edge of each bar is set out according to the requirements of the pattern effect desired with projections F' and gaps F<2>. The projections F<1> bring the sinkers A with which they register close up to the falling- bar C, and these sinkers bring the lower thread to the face of the work. The other sinkers A are allowed by the gaps F<2> to stand back of the falling-bar in the position shown in dotted lines, and these bring the upper thread of their loops to the face. By moving the bars F longitudinally under control of the pattern-chain, different pattern effects are obtained. If, however, dividing- sinkers A are held back in the position shown in dotted lines while the needles D descend and draw loops, they cause the lower thread to be brought to the face, and if the jack sinkers B are notched at B', those located between dividing sinkers standing in the position shown in dotted lines also bring the lower thread of their loops to the face, thus giving vertically striped pattern effects.

Title: Catalytic conversion of hydrocarbon oils
IPC: C10G11/18
Filed: 1942-09-24
Abstract: <PICT:0569185/IV/1> In a process for the catalytic conversion of hydrocarbon oils into motor fuels of the kind in which higher boiling hydrocarbons are cracked in one reaction zone while lower boiling fractions are refined, reformed, polymerized in another reaction zone at substantially lower temperatures than those used for converting the higher boiling hydrocarbons, the contaminated catalysts from the reaction zones are mixed and passed to a common regenerating zone while part of the catalyst from the high temperature reaction zone is passed directly to the low temperature zone.  The lower boiling fractions may be those obtained from the conversion of the high boiling oil or extraneous fractions introduced separately to the system.  In operation, crude heavy oils are converted while flowing upwardly, admixed with catalyst through reactor 28 while lower boiling fractions are reformed, refined or polymerized in the lower temperature reactor 45, the catalysts being separated in separators 31, 47 and returned through line 32, 83 and 48, 84 to the regenerator 82; part of the unregenerated catalyst from separator 31 being passed direct to the reactor 45. The regenerated catalyst passes to separator 86 and thence through line 23 in part to mix with the vapours passing in line 22 to reactor 28 and in part through line 43 to mix with fractions flowing through line 44 to reactor 45.  When feeding low boiling fractions produced in the process to the second stage, these are obtained from top of fractionating tower 39 and are fed direct through line 41, 44 to reactor 45 or may be first treated to separate gasoline or light gases for polymerisation, by treatment in absorption plant 68, 75.  Extraneous fractions are fed through line 98.  The crude is vaporized in coil 12 and superheated in coil 21; vaporization may also be effected by heat from the regenerated catalyst.  Temperatures of 800-950 DEG  F. in zone 28 and 400-700 DEG F. in zone 45 are specified.  0.5 to 10 parts of catalyst may be used per weight of the fluids.  Specification 552,334, [Group III], is referred to.

Abstract: 378,907. Composite wood blocks or tiles; floors; parquetry. LANG, A. B. D., 17, King Street, London. May 11, 1931, No. 13926. [Classes 20 (iv) and 87 (i).] A composite wooden tile or like member is formed of sections of wood cemented together with the grain perpendicular to the exposed surface, the length of each section being considerably greater than its width. The tiles may be made by cementing together, e.g. by means of casein, a number of strips or laminae a, e.g. of beech, spruce, or Douglas fir, under pressure to form a balk, and dividing the balk laterally to form the tiles b, which may be waterproofed by impregnating with paraffin wax, copal, or gum. The severing of alternate tiles from the balk may be effected by a coarse cut saw to provide a good keying surface on one side of each tile ; alternatively, a backing of fabric, such as hessian, may be used for this purpose, or strips of ply wood with chamfered edges may be applied. The edges of the rear surface may be cut away, as at c, to receive jointing material d for.connecting adjacent tiles. Thin strips of metal, such as brass or zinc, may be inserted between the laminµ to form non-skid surfaces on the tiles. The tiles mav be tinted and/or compressed to receive a polish and to harden them.
