Title: Method for treating subterranean formations
IPC: C06B43/00
Filed: 1960-08-29
Abstract: 917,572. Wells; blasting charges therefor. DOW CHEMICAL CO. Aug. 29, 1960 [Sept. 4, 1959; Oct. 15, 1959], No. 29740/60. Classes 9 (1) and 85. A subterranean formation transversed by a well is treated by detonating an explosive contained in the interstices of the formation, the explosive being a liquid mixture of a liquid oxidizer and a liquid fuel. The oxidizer which is used in an amount exceeding the stoichiometric amount required for complete reaction with the fuel comprises red or white fuming nitric acid, a mixture of sulphuric and fuming nitric acids, halogen, hydrogen peroxide, or perchloric acid. The fuel comprises a lower hydrocarbon, nitro-alkanes, nitro-aranes, aliphatic alcohols, ethers or esters, aryl or aralkyl esters or a liquid dispersion of finely divided solid fuel. The explosive may be detonated by shock, blasting cap or electric current, the fuel and oxidizer being fed into the interstices separately, or mixed together with emulsifying and sensitizing agents. Where the pressure and temperature of the formation are suitable an explosive emulsion is pumped into the well, a rubber plug is inserted above the emulsion, a buffer liquid is pumped into the well above the plug, a second plug is inserted above the buffer liquid, a chemical igniter is pumped into the well above the second plug, a third plug is inserted above the igniter, and a flushing liquid is pumped into the well to force the igniter into contact with the emulsion to cause the explosion which increases the permeability of the formation. The flushing and buffer liquids are the same fuel as is present in the emulsion, and the chemical igniter is a liquid such as furfuryl alcohol or aniline or mixtures thereof. The treatment of the formation may be preceded or followed by hydraulic fracturing.

Title: Method and apparatus for correctly presenting chain links for welding
IPC: B21L3/02
Filed: 1950-12-05
Abstract: 680,396. Making chains. ESSER, P., (trading as MEYER, ROTH & PASTOR). Dec. 5, 1950 [Dec. 19, 1949], No. 29765/50 Classes 83 (ii) and 83 (iv). A method of automatically correctly presenting chain links, whose width of clear opening is equal to at least twice the chain wire diameter, in a chain welding machine comprises mechanically testing the long side of each link for straightness and when the test shows the side remote from the welding electrodes to be divergent due to the presence of the joint, the link is turned through 180 degrees before it reaches the electrodes. Mechanism according to the invention is attached to the guide-rail 11 of a chainwelding machine so that between the feed steps of the chain one link stands upright centrally over a push-rod 10 which is slidably mounted between two angle-pieces 16 which support the chain link. The angle-pieces are supported on an upper slide part 17 movable in relation to the rest of the slide 15, the part 17 being pressed upwards by a spring 18 and the end of a lever 19 fulcrumed on the slide. The slide 15 is operated in synchronism with the chain feed conveyer by a cam 12 (Fig. 4) and a spring- loaded angle-lever 13. The rod 10. is so adjusted relatively to the angle-pieces 16 that the rod is only depressed by the divergent form of an incorrectly presented link. Depression of the rod operates the two-armed lever 19 which by means of a push-rod 22 disengages a pawl 23 which holds up a track 24 upon which rides a roller 25 on an angle lever 26 pivoted on a slide 38. The slide 38 is reciprocated by one arm of an angle lever 31 pivoted at 32, the other arm being connected to the slide 15. As the slide 15 descends through the action of lever 13 and cam 12, an arm 29 on the slide permits the track to be drawn downwards by a spring 30 and rotation of the lever 26 about its pivot brings feed-members 27 and 28 into engagement with the chain links 39 and 40. Further movement of the lever 31 moves the slide 38 together with the feed members until the link 39 is against a link 42 held by a spring stop 41, whereupon the link 40 tips through 90 degrees (Fig. 6). This turning movement is assisted by an abutment 43 on the slide 38 and a hook 44 on the slide 15 draws the link downwardly. As the chain moves through the welding machine, two link pitches at a time, the lower end of the link 40 catches the hook 44 and is turned through a further 90 degrees into the correct position. After completion of the chain feed step the lever 13 lifts the slide 15 and the lever 29 raises the track 24 into engagement with the pawl 23 and the push-rod is now beneath the next upright link. If the next link is in its correct position the rod 10 is not depressed and thus the pawl is not released from the track so that the lever 26 is held in its raised position by the roller 25 and reciprocates with its feed members moving above the chain links.

Title: Improvements in or relating to shock absorbers for vehicles
IPC: B60G17/08
Filed: 1933-10-28
Abstract: 430,978. Controlling shock-absorbers. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. Oct. 28, 1933, No. 29989. Convention date, Oct. 29, 1932. [Class 108 (iii)] In a vehicle having a brake and a resilient suspension, a shock-absorber is provided to check the rebound of the suspension the shock - resistance automatically increasing and decreasing with increase and decrease respectively in the degree of application of the brake. In the construction shown in Figs. 1, 3, the front and rear shock-absorbers are connected by rods 20, Fig. 3, to arms 22 on a cross-shaft 25, one arm being connected by a link 62 to a cross-lever 60 pivoted at its ends to the stems 56, 58 of spring-pressed pistons 48, 50 slidable in cylinders 42, 44. The cylinder 42 is connected through a pipe 40 with the master cylinder 28, Fig. 2 of an hydraulic brake assembly, and the cylinder 44 with a source of pressure such as the oil pressure pump of the lubricating mechanism or the water-pump of the cooling mechanism of the engine. Increase of pressure in either cylinder 42 or 44 due respectively to depression of the brake-pedal 30 or to increase in speed of the engine causes rotation of the lever 60 about one of its ends and consequent movement of the arms 22 and rods 20 to stiffen the shock-absorbers. In another construction, Fig. 4, the pistonstem 74 of the brake-connected cylinder 66 abuts an arm 78 coupled through a cross-rod 82 with rods 72 connected to the front shockabsorbers, while the piston-stem 76 of the pump-connected cylinder 68 abuts a lever 80 coupled through a cross-rod 84 with rods 70 connected to the rear shock-absorbers. The rods 70, 72 have pin-and-slot connections thus permitting adjustment of the front shock-absorbers independent of the rear shockabsorbers on depression of the brake pedal, and adjustment of all the shock-absorbers on increase of pressure in the cylinder 68 due to increase in speed of the engine. The Specification as open to inspection under Sect. 91 comprises also the construction shown in Fig. 5 (Cancelled), in which a bell crank 96, 98 pivoted at 99 to rods 100 connected to the front and rear shock-absorbers is acted on by the piston-stem 94 of a pumpconnected cylinder 90 and by a Bowden cable 108 operable by the driver from the dashboard 110, the cable having a pin-andslot connection with the arm 96 so as to be unaffected by movement of the crank due to the pressure cylinder. This subject-matter does not appear in the Specification as accepted.

Title: Pre-annealing treatment of titanium metal
IPC: C22F1/00
Filed: 1955-10-21
Abstract: Before annealing titanium or titanium-base alloys at a temperature not exceeding 800 DEG C., a composition comprising an alkali metal nitrate is applied to the surface thereof, the effect of said composition being to make easier the subsequent removal of scale in a pickling solution such as one comprising nitric acid and hydrofluoric acid.  The nitrate should have a melting point below the annealing temperature and is preferably sodium nitrate.  To reduce its fluidity, the nitrate may be admixed with a diluent such as one or more alkali metal carbonates, e.g. sodium carbonate; a suitable composition is, by weight, nitrate 10-100 per cent, diluent 90-0 per cent.  The composition may be applied (a) as a powder by sprinkling on a titanium surface which has been previously cleaned and wetted by a detergent solution, or (b) as a boiling, saturated solution. Annealing is generally performed at 650 DEG -750 DEG C. for 3 hours to 1/2 -hour.

Patent GB-303772-A (GB)
Abstract: 303,772. British Celanese, Ltd., Dreyfus, H., and Haney, C. I. July 7, 1927. Addition to 256,663. Acetic and other aliphatic acid anhydrides are produced by heating the vapours of the acids (which may be dilute) and the anhydrides are condensed while carrying away the water by the vapour of an "entraining liquid" such as carbon tetrachloride, petrol, benzene, mixtures of two or more of these substances, or mixtures of ether with petroleum ether, but excluding such liquids as are solvents for the anhydride and have higher boiling-points than water. The vapour of the entraining liquid may be added to the acid vapour before or during the production of the anhydride or before or after the cooling of the vapour. The production of the anhydride may be effected at 500-1200‹ C., for instance by passing through silver, earthenware, copper, or other tubes, with or without the use of catalysts. The invention is described with reference to acetic anhydride. The gases from the reaction zone 1 are passed through a pipe 2 into a steam-jacketed vessel 3 containing boiling entraining liquid 4, the gases being maintained above the boiling-point of the anhydride, for instance at 110-140‹ C. before entering the vessel 3. Part of the anhydride condenses in the vessel 3 and some is entrained by the vapour of the liquid which rises through a column 5 the trays of which are kept at 78‹ C. (for benzene). A large proportion of the entrained anhydride condenses and falls back into the vessel 3. The vapours from the column 5 pass to a condenser 7, the condensate in the receiver 8 separating into two layers. The benzene layer (containing some anhydride) may be distilled to recover the anhydride or may be returned to the vessel 3. The anhydride is finally separated from the entraining liquid by distillation. Specifications 256,663 and 279,916 are referred to.
