Abstract: A flat belt clamping pulley securely clamps the end of a flat belt to the pulley without requiring fastener holes being provided through the end of the flat belt. The design of the flat belt clamping pulley enables the pulley to be economically constructed without requiring difficult or troublesome machining steps.

Abstract: A come-along for pulling loads includes a rope winding mechanism that enables the rope to be wound and fed out smoothly. The rope winding mechanism includes a positioning hole that reduces the angle between the secured end of the rope and an axial tube about which the rope is wound. The come-along also includes a rope securing mechanism. The secured end of the rope has a seal head that fits through an installation hole and rests against the positioning hole. A helical slot around the axial tube enables the rope to wind evenly.

Abstract: The tensioning device for belts and the like comprises a supporting base (2), a winding reel (6) which can rotate relative to the base (2) about a respective axis of rotation (A1), a ring gear (13) which rotates integrally with the reel (6), an operating lever (14) for rotating the reel (6) in a first predetermined direction of rotation (S1) for winding the belt, a ratche mechanism (39), operating on the ring gear (13) and designed to prevent the reel (6) from rotating in a second direction of rotation (S2) opposite to the first predetermined direction (S1), the ratchet mechanism (39) comprising respective release means for allowing belt unwinding by reel (6) rotation in the second direction of rotation (S2). Further, the ratchet mechanism (39) comprises a first tooth (19) for engagement with the ring gear (13), the first tooth being designed to oscillate about two respective axis of oscillation (O1, O2).

Abstract: A hoisting and pulling device has a frame body (13) made by integrally forming a speed reducer side frame (13b) on an outer peripheral edge surface of the frame body, a drive side frame (13a) on the outer peripheral edge surface of the frame body, and a frame connection section (16) on the outer periphery of a load sheave receiving section. The speed reducer side frame (13b) rotatably supports a speed reducer gear (3) and has a speed reducer side cover installation section (15b). The drive side frame (13a) has a drive side cover installation section (15a). The frame connection section (16) has guide grooves (22a, 22b) for guiding a chain (11) run around the load shave. Both frames (13a, 13b) have hook installation holes (24) for rotatably supporting a hook for suspending a body frame on the load side. The structure above reduces the number of parts and assembling man-hour and makes the structure simpler, reducing the size and costs.

Abstract: A hoisting apparatus with a horizontal stabilizing means for a load holder is provided. This apparatus comprises a base secured to a ceiling, a load holder, to which a load is detachably attached, a pair of cables extending between the base and the load holder, and a drive means mounted on the base, which is operative to take in or let out the cables from the base. The horizontal stabilizing means includes a shaft horizontally supported in the load holder to be freely rotatable, around which the cables are wound in opposite winding directions to each other. The horizontal stabilizing means is operative to correct an inclination of the load holder in a horizontal position by unwinding a required length of one of the cables from the shaft and at the same time winding the same length of the other one around the shaft.

Abstract: A process for gasifying coal to produce carbon monoxide and hydrogen in which a first stream of coal is burned without bed formation in combustion zone in the presence of water under oxidation conditions to produce gases comprising carbon dioxide and steam. A second stream of coal is maintained as a fluid bed in a separate gasifier zone by upflowing carbon monoxide and steam from the combustion zone while being gasified under reducing conditions to produce carbon monoxide and hydrogen. A high sulfur carbonaceous material from an external process comprises at least in part said first stream of coal entering the combustion zone and the sulfur dioxide produced therefrom in the combustion zone is reduced entirely to hydrogen sulfide in passage through the fluid bed gasifier zone.
