Title: Improved subsurface well packer assembly
IPC: E21B23/06
Filed: 1965-07-28
Abstract: 1,085,767. Wells. CAMCO Inc. July 28, 1965 [Aug. 10, 1964], No. 32341/65. Heading E1F. A packer assembly comprises a mandrel 2 having an abutment body 3, packing 17 surrounding the mandrel below the body, an abutment 21 and cylinder 24 slidable on the mandrel, a chamber formed between the mandrel and cylinder, a piston 26 in the chamber dividing it into upper and lower sections 27, 28 so that an increased pressure in the upper section will push the cylinder and abutment 21 toward the body, and a production tubing 1 extending from the body and having a connection 29 with the piston to ensure that the piston is fixed relative the abutment body. The mandrel forms part of a second production tubing. To set the packer a tool with packing 54 is lowered into the mandrel so that magnetic switches 51 fire an explosive charge to project latches 52 into the mandrel and connect the section 28 to a low pressure chamber 53. Fluid at the well pressure below the tool passes through the tool and through parts 33 into the section 27 to set the packer, a pin (not shown) depending from the piston engaging a ratchet so that the position of the piston relative to the abutment remains fixed to hold the packer set. As the cylinder moves upwardly slips (not shown) carried by the cylinder are set by tapered surfaces on the abutment 21. The body has spring loaded slips which are also urged outwardly by the well fluid in the annulus below the packer flowing through a bypass in the packer. The packer is freed by rotating the tubing 1 to unscrew the threads 29 after shearing a pin 12, by raising the tubing and body to remove the load from the packing, and by lifting the abutment 21 to free the lower slips. The opposing surfaces of the packer and the tubing I are lined with a layer 60 of waxy solid plastic compound.

Abstract: 903,897. Reducing metallic oxides. KELLOGG CO., M. W. Sept. 22, 1960 [Oct. 5,1959], No. 32568/60. Classes 72 and 82 (1). A method of reducing granular metallic oxides comprises introducing into a molten metal bath a reducing agent and injecting the granular metallic oxide into the molten metal whereby the oxide is reduced and the molten metal formed is removed. As shown, applied to the reduction of oxidic iron ore, a bath 12 of pig iron is formed and oxide ore mixed with a liquid, solid, or gaseous, carbonaceous reducing agent and slag forming materials is introduced below the metal surface through a lance 11. Air from a regenerator 15 is fed to the same end of the furnace, part of this air being used to burn oil from a burner 18 and the remainder to burn carbon monoxide produced by the reaction between the reducing agent and the ore. When the air is changed over to the other end of the furnace, the ore and other additions are injected through a lance 26. Metal is removed from the furnace through an opening 23 and slag through an opening 24. When the reducing agent does not produce large quantities of gas, e.g. coke, it may be added at the centre of the furnace only. Chromium and manganese oxides may be reduced to metal by the process.

Title: Friction clutches
IPC: F16D13/50
Filed: 1971-07-13
Abstract: 1348791 Friction clutches TOYOTA JIDOSHAHANBAI KK 13 July 1971 [13 July 1970 31 July 1970 29 Aug 1970 28 Dec 1970] 32904/71 Heading F2C In a diaphragm spring clutch resilient means 7 (Fig. 1) are provided between the inner race of a bearing 31, attached to the output shaft 5 of the clutch, and the driven plate 6 (or the hub 61 on which it is supported) to separate the driven plate 6 and the flywheel 2 when the clutch is disengaged. In the embodiment shown in Fig. 1 this means is a frusto-conical member 7 of elastomeric material such as rubber, which is compressed on engagement of the clutch. This member 7 may be replaced by a helical spring (70) (Figs. 4 and 5, not shown). A form of construction which allows for wear of the clutch facings 68 is exemplified by that shown in Fig. 12 in which an annular resilient member 73<SP>1</SP> provides the separating force, which force is less than the frictional force between cylindrical members 71<SP>1</SP> and 72<SP>1</SP> created by resilient rings 74<SP>1</SP>, relative movement between the cylindrical members only occurring when the clutch facings have worn and compensating for that wear. Further embodiments which compensate for wear all comprise two such coaxial cylinders but the form of the resilient ring 73<SP>1</SP> may be modified (Figs. 17 to 21, not shown) and this may be replaced by a helical spring (Fig. 22, not shown). An embodiment in which the ring such as 73<SP>1</SP> is dispensed with has a ring of square cross-section between the cylinders, either in the inner face of the outer cylinder (Fig. 6, not shown) or in the outer face of the inner (Fig. 9, not shown) a wedging action caused by the shape of the groove providing the resilient action. The shape of the rings 74<SP>1</SP> of Fig. 12, can also be changed (Fig. 14, not shown) and there may be only a single ring (of rectangular cross-section) (Fig. 15, not shown). In all those embodiments the resilient means can act against the end face of the hub 61 instead of the plate 6. As shown in Fig. 1 the clutch plate has a disc plate 62 and a sub plate 63 between which is a resilient member 65, to enable the clutch smoothly to engage.

Title: Improvement in process of treating casein varnish-finished coated fabrics or articles and products thereof
IPC: D06N3/16
Filed: 1928-11-10
Abstract: 301,024. Du Pont de Nemours & Co., E. I., (Assignees of Nickowitz, M. N.). Nov. 23, 1927, [Convention date]. Coating-processes.-Articles are coated with casein varnish which is subsequently halogenized, for instance by treatment with bromine. The treatment may be applied to articles previously coated with rubber, pyroxylin or oxidised oil. The casein varnish may be halogenized before application. In one example, a spreader coat of a composition comprising 40 1b. of crepe rubber, 5 lb. of zinc oxide, 8 ozs. of sulphur, 4 ozs. of tetra-methyl-thiuram-disulphide accelerator, 1 lb. of carbon black, 5 1b. of mantan wax, and 48 1b. 4 ozs. of barytes, dissolved in gasoline is applied, the face is then dusted with magnesium carbonate, and the material is vulcanized at 240‹ F., and is then varnished with a casein varnish consisting of 8000 grams of casein, 1500 c.c. of water, 500 c.c. of glycerin, 8000 c.c. of alcohol, 700 c.c. of ammonia, and 700 c.c. of formalin. In making this varnish, the casein and water are warmed together and allowed to stand overnight. The glycerin and ammonia are then added, and the casein dissolves. Alcohol and formalin are then added. Before use, water in the proportion of one part to seven of the composition added. After application to the material, the varnish is treated with a 4 per cent solution of bromine in carbon tetrachloride, and the surface of the material neutralized in an atmosphere of ammonia. Two or more coats of the casein varnish may be used to provide a film thick enough to prevent the bromine from penetrating to the rubber coating. In a further modification, the sulphur and accelerator are omitted from the rubber compound, and the material is vulcanized by treatment with sulphur chloride vapour or solution. The casein varnish is then applied and halogenized. Surface coatings of pyroxylin or of oxidized linseed or Chinawood oil mav also be treated wtih casein varnish in the same way. Other halogens may be employed instead of bromine, or halogen compounds such as sulphur chloride or sulphur bromide.

Abstract: 1275188 Conveyer systems STANDARD ALLIANCE INDUSTRIES Inc 7 July 1970 [3 Sept 1969] 33022/70 Heading B7L In a power and free conveyer system having movable work carriers 22 each provided with front and rear trolleys 24, 26, the drive chain 86 has a plurality of pairs of spaced drive lugs, one drive lug 92 of each pair being pivoted and cooperable with pivoted and counter-weighted flop dogs 34, 35 on the front trolley 24 to move the carrier, the other drive lug 94, which is shorter than lug 92, being fixed and co-operable with an abutment 110 on the rear trolley 26 to move the carrier, the arrangement being such that when the spacing between the drive chain 86 and the carriers 22 is increased by a predetermined amount, the fixed drive lug 94 is no longer engageable with the abutment 110, the pivoted lug 92 being engageable at all times with the dogs 34, 35. The pivoted and fixed lugs are spaced farther apart than the front and rear trolleys in each carrier so that in normal operation, with the lug 92 engaged with the front trolley, the fixed lug 94 is spaced behind the rear trolley so that if the front trolley should be accidentally disengaged from the drive chain, for example on an inclined section of track, the fixed lug 94 catches up the rear trolley, engages the abutment 110 and moves the carrier forwards. In certain sections of the conveyer system, for example in "close pack" areas, the spacing between the drive and carrier tracks is increased, as described above. On arrival at the "close pack" area, the first work carrier is automatically disengaged from the drive chain by known means. The following carrier bumps into the first carrier, and becomes disengaged of a cam-plate 58 on the rear trolley of the first carrier, succeeding carriers also being disengaged in a similar fashion, the carriers becoming "nested" together with the flop dog 34 of each inside a slot 66 in the cam-plate 58 of the preceding carrier. After some time, the first carrier will have been pushed by the following carriers through and out of the "close pack" area and will then automatically become reengaged with the drive chain, normal spacing between the tracks 10 and 12 being resumed at the end of the close pack section.
