A zero-stopping incrementer operates on the recognition that half of all digital values that require incrementing will be even numbers; that is, the least significant bit (LSB) is a binary "0". Incrementing such a number merely requires changing the LSB from a binary "0" to a binary "1". For odd numbers (i.e., those where the LSB is a binary "1"), the zero-stopping incrementer searches for the first binary "0" beginning with the LSB. Once found, that binary "0" is changed to a binary "1" and all...

A method of stopping of a winding machine that hoists and lowers an object prevents abrasion of the electromagnetic brake and the descent of load. The winding machine, which winches a load up or down in response to a torque command T.sub.REF to the electric motor M produced by the speed controller ASR in accordance with the a speed command N.sub.REF generated by the speed command generation circuit NRC, operates at the stopping of the machine to cease the motor control if the motor speed N.sub.F...

A method for stopping replay tornadoes in a processor. The method of one embodiment comprises scheduling an instruction for execution speculatively. A determination is made whether the instruction executed correctly. The instruction is routed to a replay mechanism if the instruction did not execute correctly. A determination is made whether a replay tornado exists. The instruction is routed for re-execution if the instruction executed incorrectly and no replay tornado exists. Breaking the replay...

A chair includes an upper frame disposed above and pivoted to a lower frame. A stopping device includes a slide mounted slidably on the upper frame, and a stopping member. The slide is slidable between a first position, where the stopping member is offset from a rear plate of the lower frame in a longitudinal direction, and a second position, where the stopping member is aligned with the rear plate in a vertical direction. A cam mechanism includes a cam connected movably to side plates of the lo...

In an elevator emergency stop device wherein emergency stop of the elevator cage (20) is achieved by generating frictional force at a sliding part (11) and guide rail (1) by pressing a sliding part (11) against guide rail 1 using a wedge-shaped element (3), in wedge-shaped element (3), the dimension in the direction perpendicular with respect to the sliding faces on the guide rail (1) and sliding part (11) is changed in accordance with the braking force.An elevator emergency stop device can ther...

A mine stopping installed in a mine passageway includes a lower tier of elongate panels extending generally vertically in side-by-side relation from a floor of the passageway. Each panel of the lower tier has a lower end adjacent the floor and an upper end spaced from a roof of the passageway. An upper tier of elongate panels extends generally vertically in side-by-side relation from the lower tier of panels to the roof. An upper end of each upper tier panel is adjacent the roof and a lower end ...

An engine starting and stopping device includes a first roller selectively abutting the flywheel of an engine for rotation on a first shaft in response to rotation of the flywheel. A second roller abuts the first roller and rotates in response to rotation of the first roller. A second shaft and an overwind clutch couple the second roller with a third roller such that the third roller rotates in response to rotation of the second roller. The third roller abuts a spring housing and causes rotation...

An engine starting device includes a roller selectively engageable between the crankshaft of an engine and an arbor. The roller causes the arbor to rotate in a loading direction in response to rotation of the crankshaft. Rotation of the arbor loads an elastic member. A locking mechanism, such as a ratchet wheel and pawl may be used to keep the elastic member loaded until it is desired to startup the engine. Engine startup is initiated by disengaging the pawl from the ratchet wheel and permitting...

Stopping device for a transport trolley which can be moved along guidances or rails (2-3), whereby the transport trolley (4) is provided with driving wheels (7) which cooperate with a driving axle (6) and which, by means of a lever (14) with a contact wheel (17), can be set at different angles in respect to said driving axle (6), characterized in that this stopping device (1) consists of at least a lever (20) with an ascending edge (40) and a descending lateral edge (41), prolonged by an acceler...

A method for stopping a purifying column handling an easily polymerizing compound-containing solution is disclosed, which method is characterized by lowering the inner oxygen concentration of the column below the limit of oxygen concentration by supplying an inert gas to the column while the concentration of the gas of easily polymerizing compound is in the range of 100% to the lower limit of the flammable range in volume % of the purifying column or by further supplying a reflux liquid thereby ...
