Inventor: EISENBERG BENJAMIN
IPC: C21B13/00
Filed: 1968-06-10
Abstract: 1,162,773. Producing iron. ESSO RESEARCH & ENG. CO. June 10, 1968 [Sept. 5, 1967], No.27509/68. Heading C7D. A metallized product is produced by a process consisting of feeding particulate iron ore solids through a series of fluidized beds in which the solids are progressively reduced by the countercurrently flowing, fluidizing gas and the product is withdrawn from the last bed. The process is characterized by the injection of oxygen, mixed with either steam or carbon dioxide, directly into any or all of the several fluidized beds to provide process heat. Oxidized components are removed from the reducing, fluidizing gas by regeneration plant and the regenerated gas recycled to the process. The oxygen plus carbon dioxide or steam mixtures should contain 10-80 weight per cent of oxygen to effect temperature control of individual beds of the whole process. The final reduction bed is maintained in the range 1300- 1600‹ F.

Title: Liquid wheel-balancing system
Inventor: CLAY ROBERT ALMOUNTON
IPC: B60C19/00
Filed: 1968-06-10
Abstract: 1,209,696. Wheel balancing. SUNLAND REFINING CORP. 10 June, 1968, No. 27575/68. Heading B7C. Continuous balancing, in use, of a wheel and tyre assembly is achieved by the insertion into the cavity of a tyre 12 a mixture comprising a dense weighting material 42, a less dense positional retaining material 52 and, least dense, a liquid conveyer 44, which substances, on rotation of the assembly, are centrifugally separated as shown in Fig. 6, depositing the weighting material in position within the region of the tyre having low weight. The positional retaining material, which may form a viscous gel with a portion of the liquid conveyer, holds the weighting material in position when rotation of the assembly stops, but, due to its non-drying nature, permits slow creeping of the material to compensate for subsequent inbalances created in the tyre.

Title: Improvements in and relating to the filling, closing and sealing of foldable containers
Inventor: DOLMAN HENRY JAMES
IPC: B65B7/08
Filed: 1954-09-24
Abstract: 813,784. Filling and closing foldable containers. BRECKNELL, DOLMAN & ROGERS Ltd. Dec. 23, 1955 [Sept. 24, 1954]. No. 27639/64. Class 94(1) [Also in Group XXX] In a machine for filling and closing foldable containers, e.g. bags, the containers are withdrawn from magazine 23, Fig. 2, filled with granular material through spouts 24 and deposited at positions 25A on a supporting platform. Each bag 25 is then moved by a reciprocating pusher into a pocket 1 of a horizontal chain conveyer 8 (see Group XXX) which moves it at uniform speed over a supporting surface while its mouth is folded and secured by adhesive as shown diagrammatically at A-H in Fig. 1, the sealed bags being finally transferred by a belt 72 in groups of four to a dryer 71 comprising opposed endless belts engaging the upper and lower ends of the bags. Each bag passes over two vibrating endless belts 26 co-operating with guide belts 26A, whereby its contents are compacted, and the gussets 27, 27A are then tucked in by reciprocating fingers 30, 31, Fig, 6, of which the former is lowered into the path of the bag by a parallel motion linkage 32 and the latter is operated by revolving arms 33 so as to move in a closed path such that it overtakes the bag. At the same time the flattening of the mouth of the bag is assisted by swinging plates 34, Fig 8, fitted with rollers 35 and operated in unison by meshing toothed sectors 36 to which a rocking motion is imparted by cam-operated linkage 37. The shoulders of the bag are then squared by shoes 39, Figs, 6 and 10, reciprocated vertically by cam-operated linkage 41, while the bag walls 38 are gripped between spring loaded plunger 42 carried by parallel bars 43 operated by revolving arms 44. The bars also carry blocks 46 which form a horizontal crease in the walls 38 (operation D) while surplus bag material is trimmed off by a cam-operated blade 48 co-operating with a fixed blade 47. The trimmed and creased bag is then acted on by a fixed rail 51, Fig 13, which folds the walls 38 about the crease to form a flap 52. The flap is then bent to an inclined position by a swinging plate 53 in order to pick up glue from a conical roller 54 against which it is held by a roller 55, Fig. 16, which is mounted on an axle 56 so as to be swingable towards and away from the roller 54 by cam-operated linkage 57. The axle 56 supports the plate 53. The flap is then folded and pressed against the upper end of the bag by an inclined plate 66 and a reciprocating plate 67.

Title: Improvements in and relating to electric motors operating on pulsatory or single-phase alternating current
IPC: H02K57/00
Filed: 1923-11-03
Abstract: 221,991. Fontana, C., and Ferrari, V. Nov. 3, 1923. No Patent granted (Sealing fee not paid). Rotary machines; oscillating machines; motors with unwound iron armatures. - A motor operating on pulsatory or singlephase alternating current comprises a laminated electromagnet a having internally projecting poles with inclined faces and mounted on a rotatable bushings. A laminated armature b, which may or may not be wound, has outwardly projecting poles with their faces parallel to the electromagnet polefaces and is mounted on a rotatable bushing t. A sleeve d surrounding the outer core and an inner sleeve e surrounding the shaft are formed with two sets of oppositely inclined grooves in the planes A-B and E-F, and in these grooves are located spring-pressed balls engaging with rings i, i<1> on the bushing s and shaft respectively. A key u is provided between the bushing t and sleeve e to permit of relative axial movement. The casing f is formed with a helicoidal slot g through which passes a handle h screwed into the sleeve d. The sleeves are connected together by resilient rods m engaging at their outer ends in a circular groove and fixed at their inner ends. The rods pass through straight axial slots r in the bushing t and through slots q, having the shape shown in Fig. 3, in the bushing s. When the coils of the electromagnet a are excited, the armature b is attracted in a clockwise direction. An impulse is thus given to the motor shaft by the action of the balls in the sleeve e on the ring i<1>. The core a is prevented from moving anti-clockwise by reason of the spring-pressed balls in the sleeve d located in the plane A-B, but is moved forward by the blow delivered by the armature. When the current in the coils falls to zero, the rods m separate the two cores, and at the next current impulse the same cycle of operations is repeated. In order to decrease the speed of the shaft, the handle h is moved along the slot g, and this results in an axial movement of the sleeves d, e. At the same time, the outer ends of the resilient rods m pass along the inclined portion 4 - - 2 of the slot q, which causes relative angular movement of the cores and consequent diminution of the air gap. Continued movement of the handle causes the balls lying in the plane E-F to engage with the rings i, i<1>, and the motor is reversed. Further movement brings the rods m into the portion 3-1 of the slot q and the speed of the motor is increased owing to the larger air gap formed by the separation of the cores. The core a may be fixed in the casing, in which case the oscillatory movement of the armature is converted into rotary movement of the shaft. Current is led in by slip-rings l.
