The invention relates to a procedure for stopping an elevator car at a landing, in which procedure the travelling velocity and position of the elevator in the shaft are measured and a distance from the landing, i.e. a deceleration point at which deceleration is started, is determined for one travelling velocity, i.e. a reference velocity. According to the invention, the deceleration point is changed in proportion to the difference between the measured travelling velocity and the reference veloci...

A door system for closing a doorway in a mine stopping includes a door hinged adjacent the doorway for swinging relative to the stopping between a closed position and an open position. A keeper is mounted in fixed position relative to the doorway. A latch mechanism is cooperable with the keeper for latching the door in its closed position. The latch mechanism has a detent portion and is operable to move the detent portion between a latching position in which the detent portion engages the keeper...

A vehicle stopping device having a panel of material with a split extending from one end of the panel toward an opposite end of the panel, a tactile surface formed adjacent to one of the panel and adapted to attach to a tire rolling thereover, and a reinforcement sash affixed to the panel of material and extending in a partial loop around the split seam. The reinforcement sash has a first end affixed adjacent to the tactile surface and a second end affixed to the tactile surface on an opposite s...

Installation for controlling trains defining allocated cross-overs with conductor loops, in accordance with a normal program P1n and an interference program P2n. Installation characterised in that the ground equipment of each block comprises a frequency generator GF producing a normal mode frequency F1, an interference mode frequency F2 and a frequency F3 to be modulated, supplying a mode selector SM, so as to provide a frequency signal FSn as a function of an occupation signal OCC (n+1) receive...

A method and device for detecting the presence of a running thread takes advantage of the inherent physical irregularities of the thread to generate an alternating current signal as the thread passes through a capacitive element. The variations in capacitance resulting from the running thread are detected and amplified as an alternating current electrical signal, which disappears instantly with thread stoppage or breakage.

A method of controlling the fluid pressure of an inflatable stopping bag used to block the fluid flow through a fluid conduit comprises pressurising the bag using a pressure regulator which operates to regulate the pressure of the bag as a function of the instantaneous pressure in the pipe upstream of the stopping bag.

A device for shutting off or stopping a marine engine ignition system utilizing a transmitter for generating a wireless signal. The wireless signal is only generated upon association of the transmitter with a mass of water. A receiver acquires the wireless signal and generates a disconnection signal which interrupts the operation of a marine engine.

Method and apparatus for determining the stopping point of an iterative decoding process. In one embodiment the estimated values of an iteration of an iterative decoder are provided to a signature circuit. If the signature does not differ from the previous signature developed from a prior iteration, or the signature developed from an iteration prior to the previous iteration, the decoding stops. The variance may also be tested and compared to a threshold as a criteria to stop the iterative decod...

An aqueous, clear, cleansing composition comprising (a) a cleansing effective amount of a potassium salt of a long chain alkyl carboxylic acid or mixture thereof, the pH of said composition being from about 10.0 to about 11.0.

A device for controlling a process of stopping a laser printer having a printing unit including a sensitive drum and a fixing unit. The stopping process control device is provided with a detecting unit for detecting errors occurring in the laser printer, a determining unit for determining whether or not an error detected by the detecting unit is very serious, and a control unit for controlling the printing unit and the fixing unit. The control unit stops the printing unit and the fixing unit aft...
