Title: Method and device for monitoring an edge of a moving web
Inventor: KOIRANEN JUKKA
IPC: B65H23/038
Filed: 1993-12-13
Granted: 2000-04-18
Abstract: Method and device for monitoring a moving web, such as a wire in a paper machine, a felt, or a material web, such as a board or paper web. A bar of radiation beams is directed at the face of the web to be monitored by a series of transmitters in a direction transverse to the direction of movement of the web. Radiation reflected from the web and the background is detected by a series of receivers. The measurement signals obtained in this way are passed to an electronic unit in which a quantity that characterizes the monitoring of the web is determined from the measurement signals. The approximate location of the edge, the edges, or of corresponding discontinuities of the web is detected "digitally" on the basis of the radiation beam of the radiation transmitter in whose area the greatest change takes place in the received radiation. The precise location of the edge or equivalent of the web to be monitored is determined analogously by comparing the amplitudes of the signals of the adjacent receivers placed closest to the last-mentioned radiation transmitter with one another.

Title: Battery pack retention system and apparatus therefor
Inventor: MCCORMICK TIMOTHY P
IPC: H01M50/204
Filed: 1994-08-22
Granted: 1998-08-18
Abstract: The system includes a battery charger (300) and a battery pack (100). Upon insertion of the battery pack (100) into a retention area (303) of the battery charger (300), a battery pack channel (101) and a corresponding battery charger rail (305) align the battery pack electrical contacts (201) with the electrical contacts (309) of the battery charger. In order to ensure that a reliable electrical connection is made between the two sets of contacts (201, 309), a compliance rib (501) is disposed within the channel (101) of the battery pack (100). The compliance rib (501) creates an interference between the rail (305) and the channel (101), consequently, creating a force against the rail. The interference is calculated to create a sufficient force in combination with the force created by the weight of the battery pack (100) such that the force of the battery pack meets or exceeds the force created by the set of electrical contacts in the battery charger.

Abstract: In a method of recognising an optically encoded binary word, the word is chosen from a subset of binary words for which W?T=0 if W=T, W?T=1 if W?T is true, where T is the target word, W is the word to be compared and ? is the operation formula (I). The word is recognised by carrying out in the optical domain a bit-wise Boolean AND operation. The operation is carried out on the word to be recognised and the complement of the target word. The AND operation may be carried out by introducing the word to be recognised and the target word into a nonlinear crystal and detecting the second harmonic output from the crystal. The complement of the target word may be generated by a fixed word-forming network. The method may be applied to recongnising the address of a packet on an optical network.

Title: Procedure for starting an elevator
Inventor: HAKALA HARRI
IPC: H02P6/18
Filed: 1995-09-28
Granted: 1999-04-06
Abstract: The invention relates to a method for starting elevator machinery driven by a synchronous motor. The synchronous motor is fed via a frequency converter, and a traction sheave is connected to the motor to move the elevator car by means of hoisting ropes. According to the invention, the angle of the magnetic field of the stator is determined when the elevator stops. When the motor is started again, a new value of the angle of the magnetic field of the stator is determined on the basis of the change in the load signal, and the frequency converter is so adjusted that a magnetic field whose angle corresponds to the new angle of the magnetic field of the stator is generated in the motor.
