Title: Method for constructing a blast furnace
IPC: E04G21/14
Filed: 1976-09-30
Abstract: 1518879 Erection of blast furnace SANKYU INC 30 Sept 1976 [2 Oct 1975] 40534/76 Heading E1S [Also in Divisions B8 and F4] A blast furnace is built up from prefabricated sections, each including at least some of the ancillary apparatus as well as the furnace brickwork, carried to a prepared foundation on a carriage and raised in turn so that the furnace is built up from below. the carriage forming part of the bottom structure of the furnace. A foundation surrounded by normal furnace support pillars 8 is served by rails carrying a platform 30 liftable from the rails by jacks 302. A permanent scaffolding 32 is erected on the supports 8 and carries lifting devices 33 with depending rods 336. The top prefabricated section A, including a downcomer part A2, is secured to a frame f and stayed in position before transfer on the carriage 30 to the foundation Fig. 14. Some of the rods 336 are secured to the frame f and the section A is lifted to allow a second section B secured to a support frame 34 to be positioned below it. The jacks 302 are extended to bring the section B to a position where it is joined to section A, lifting rods 336 are connected to the frame 34 and both sections lifted together to allow the carriage 30 to be removed. The support frame f is removed from the top section, Fig. 17. The next sections are supported by uprights 35 and frame 34 forming part of the access platform support tower where the furnace is completed. As each section is joined to the one above and hoisted to allow a further section to be placed on the foundation, the support tower uprights 35 are connected by lugs 36 and wedges k to the support pillars 8, Fig. 20, so that the upper part of the furnace is supported clear of the foundation, Fig. 21. A belly section F, having a ring girder 37 is raised to a position where it and all previously positioned sections can be supported on the pillars 8 through the bottom beams 35a of the platform support towers. Some of the lifting units 33 are connected to lugs on the girder 37 to assist in lifting a belly section G having a mantle ring 39 with lugs 39a. After the section G is joined to the section F, a further set of lifting devices are mounted on the lower frame of the platform support tower 35 to lift and hold in place a bustle pipe 12, Fig. 26. The carriage 30 is now modified by positioning top and bottom plates, and arrangements for supplying grout to its interior, before the modified carriage with the bottom section H is placed in position on the foundation and raised on jacks 302 to allow the section H to be joined to the remainder of the furnace. A casting frame 38, Fig. 32, is placed round the carriage, which is filled with grout and embedded in grout within the frame 38. The wheels are removed, but the jacks 302 remain extended until the grout is set, when they are removed, and wedges connecting each body section to a corresponding part of the platform tower (Fig. 12) are removed, so that the furnace is supported solely from the pillars 8 and the base.

Title: Improvements in and relating to hydraulic gear pumps
Inventor: ECKERLE OTTO
IPC: F04C2/08
Filed: 1968-08-27
Abstract: 1,243,025. Rotary positive-displacement pumps. O. ECKERLE. Aug.27, 1968 [Sept.1, 1967], No.40847/68. Heading F1F. An hydraulic gear-type pump has a driving- shaft 3 with a pinion 2 meshing with an internallytoothed gear 4, which is pressed against the pinion and a filling piece 5 by a member 10 pivotally mounted on a pin 11 that has each end slidable in a corresponding recess 13 formed in the casing 1. To load the member 10 a recess 20 adjacent an outlet passage 9 is connected by bores 21 to spaces 22 associated with two annular pistons 18, which are biased outwardly by springs 24 and pressure transmitted through bores 19. A further piston 18 seals the passage 9. The piece 5 pivots on a pin 6. The thrust exerted by the fluid in the spaces 22 is partially counteracted by the pressure of fluid leaking from the recess 20 between the gear 4 and the member 10 towards grooves 25 communicating with an inlet passage 8. The gear 4 has radial bores (not shown) between the teeth to allow the working fluid to pass into and from the tooth spaces of this gear and the pinion. The central piston 18 may be replaced by a tubular plunger (29), Fig.3 (not shown). The other two pistons may be replaced by sheet-metal rings (35), Fig.4 (not shown). Alternatively, these pistons are replaced by pistons (43), Fig.6 (not shown), made of plastics material. As shown in Fig. 8 the member 10 may abut a plate 58 at each end of the casing. Each plate is supported by a pin 59 and allows the member to exert thrust on the gear 4 only in the region of the pinion so as to minimize wear at the outer edge of the piece 5. A recess 64 and a bore 67 in each plate effect pressure balancing. A peripheral portion 61 of each plate may be rendered flexible and resilient by a slot (71), Fig.10 (not shown). In another embodiment, Figs.11 to 14 (not shown), the member 10 is pivotally secured to the casing by a pin (74) having limited freedom of movement circumferentially relative to the gear 4 so as to compensate for wearing of the piece 5, which is pivotally supported by a pin with each end slidingly lodged in a respective plate (73) mounted on the shaft 3 between the gear and pinion and the adjacent end of the casing. Each plate has a bore (82) therein to provide pressure balancing. In a modification, Fig.15 (not shown), the piece 5 is attached to said plates by a pin (92) and abuts a pin (93) allowing limited movement of the piece relative to the axis of the shaft 3.

Abstract: 903,884. Viscometers. GREAT LAKES CARBON CORPORATION. Nov. 29, 1960 [Dec. 3, 1959], No. 40923/60. Class 106 (2). [Also in Group XL (c)] Apparatus for determining the viscosity of a fluid X, e.g. concrete slurry at high temperatures and pressures, comprises a well 9 in a body of non-magnetic material containing the fluid and an iron bob 11 which may be acted on by an electromagnet 27 and which (when it hits the top or bottom 13, 14 of cavity 9) produces a sound wave picked up by a transducer 23. The fluid is subjected to pressure medium Z through valve 24B and is surrounded by a heater 26. In operation, electromagnet 27 is energized at regular intervals causing bob 11 to rise and then fall again due to gravity. When the bob ceases to hit the lower surface, i.e. when the viscosity has reached a predetermined level, a mark is made on a recorder and a second lower electromagnet 28 of the same ampere turns/inch is energized alternately with electromagnet 27. When the bob fails to hit the top surface 13 another mark is made on the recorder and when viscosity has increased sufficiently to prevent the bob 11 hitting either surface a final mark is made on the recorder.

Filed: 1969-08-20
Abstract: 1283407 Comminuting sewage; rotary drum filter and screen R N CRANDALL and C H NORDELL 20 Aug 1969 [6 Sept 1968] 41458/ 69 Headings BID B2A and B2H [Also in Division C1] The solids in a flow of sewage are lifted above the liquid level, the soft organic solids being comminuted and returned to the sewage flow, while the uncomminuted solids are conveyed away from the flow. The apparatus comprises a cylindrical screen 15 separating an influent chamber 44 from an effluent chamber 46. The screen 15 is rotated on a shaft 68 by a motor 170 through gears 176, 180 and a chain 178 so that fingers 106 projecting from the screen lift solid material from the influent chamber 44, until a cam surface 114 engages a roller 111 Fig. 9, on the frame 108, 110, Fig. 8 supporting the fingers, causing the frame to pivot about a shaft 104 against the action of a spring 112 retracting the fingers through closely fitting holes 121, Fig. 2, and depositing particles of solid T on the surface of the screen. On further rotation of the drum these particles T lift a gravity biassed plate 18, pivoted at 18c and comprising a metal backing plate 18a bonded to a rubber sheet 18b to flatten, and remove water from such solids as rags &c and to scrape soft material from sheet 18b. The particles T which are then removed from the drum by a skewmounted roller 16 rotated about the shaft 140 in the same direction as the screen 15 but at a faster speed. The roller 16 consists of flexible plates 134, and in another embodiment, may be of a smaller diameter towards the centre, Fig. 7A (not shown). The particles T are removed on a conveyor 20 to an elevator 22. Soft organic material M Fig. 11 (not shown) collects on the outside of the screen 15 and is communicated by the plate 18 which pushes this material into the holes 15a see also Fig. 4c (not shown) in the screen from which it is washed into the screen and effluent chamber 46 by the influent from the chamber 44, there being a difference in levels inside and outside the screen due to the partial blockage of the screen holes. If the screen is completely blocked a weir 52 allows an over-flow of influent directly into the effluent chamber 46.

Filed: 1972-09-07
Abstract: 1407609 Controlling multiple spindles ACME-CLEVELAND CORP 7 Sept 1972 [15 Sept 1971] 41523/72 Heading B3B A multiple spindle automatic machine tool 12 comprises a clutch and brake unit 31, 32 for each of the spindles 15, each unit being electromagnetically operated to couple the spindle via the clutch 31 to the drive consisting for example of motor 18, shaft 19 and gear wheels 21, 22, or to brake the spindles rotation relative to spindle carrier 13. Solenoid coils 81, 82 are actuated from a power source 88, 89, 90 acting through a commutator assembly 35, comprising at least two contactor rings 51-53, and a cooperating brush assembly 36 comprising brush sets 61-62 of brushes 44, 64, 65. These assemblies rotate relatively to each other due to the indexing movement of spindle carrier 13 brought about in Fig. 1 by Maltese cross mechanism 25-27 and switch the units 31, 32 on and off according to the machining cycle. In the example, the commutator is stationary. The electric circuit 79-84 shown for each brake/ clutch unit in Fig. 3 actuates the brake or clutch depending on the current polarity applied and this is determined by selector switches 91-96 which connect oppositely polarized power supplies 89, 90 to the assemblies 35, 36. Power supply 88 acts through a relay 97 to connect the supplies 89, 90 to the assemblies when the brushes have regained contact with the contactor segments in ring 51 after traversing the spaces between segments so preventing arcing. This action is provided by the spacing between segments 54 in ring 53 which causes the disconnection of relay 97 from supply 88.

Title: Permanent waving of hair
Inventor: GREEN ALVAN
IPC: A61K8/46
Filed: 1959-12-07
Abstract: A composition for the permanent waving of hair comprises an aqueous solution containing a mixture comprising a minor proportion of an amine salt of thioglycollic acid and a major proportion of an inorganic salt of thioglycollic acid, e.g. ammonium thioglycollate. The amine salt is preferably an alkanolamine salt, e.g. the monoethanolamine salt.  The composition which is preferably adjusted to a pH of 9.4-9.7 may contain 12 ozs. of a 40% w/w aqueous solution of the monoethanolamine salt of thioglycollic acid (estimated as thioglycollic acid) and 32 ozs. of a 40% w/w aqueous solution of ammonium thioglycollate per gallon of solution.  Hair may be waved by winding a tress of hair, preferably after washing and partial drying, on a roller or mandrel which preferably has a diameter greater than 1/2 -inch, applying the permanent waving composition to the wound tress and heating the wound tress sufficiently both to wave the tress and to dry the hair before it is removed from the roller or mandrel. Heating may be effected with an exothermic pad or by an electric resistance wire. Alternatively, the hair may be waved by other methods in which the tress is removed from the roller or mandrel upon completion of the action of the permanent waving reagent and, after washing, the tress is then either set by rewinding on a roller or mandrel or is manipulated into position before drying. Specifications 829,496, 833,328 and 845,508 are referred to.
