Abstract: The invention relates to a press roll arranged to interact with a second roll in the wet end of a paper or paper board machine for forming a nip between the rolls. In the press roll a surface is arranged to be pressed against the second roll and is made of an elastic material for extending the nip. In order to provide a simple and versatile structure, the surface made of an elastic material is formed by a separate shell portion which surrounds a body of the press roll and is positioned over its entire length at a distance from the body. The shell portion is supported to be stationary with respect to the body by means of end flanges provided in the ends of the body, so that the shell portion is able to yield over the entire length thereof radially inwards towards the body locally at the nip point.

Abstract: The invention concerns a coupling arrangement intended to be fitted on a vehicle and comprising an attachment part intended to be attached to the vehicle and a coupling part 22, of which parts one comprises a tubular receiving element 30 and the other comprises an elongate insertion element 4 intended to be received in the receiving element. A movable piston 34 laterally spring-tensioned towards the insertion element can be driven into a side recess in the insertion element, in which side recess the piston is kept pressed by an abutment element 62 in a first position of engagement between the piston 34 and the abutment element 62. The abutment element 62 engages laterally in the path of movement of the piston 34 and is able to be driven essentially in the longitudinal direction of the piston 34 so as to bring the piston 34 to a second position of engagement between the abutment element and the piston, in which position the abutment element keeps the piston caught, counter to the spring tensioning action, essentially outside the path of movement of the insertion element 4 in the receiving element 30. <IMAGE>

Abstract: An apparatus monitors an a.c. motor (12), a door (14) operated by the motor, a frequency converter (16) for supplying electric power to the motor (12), and a control and signal-processing means (32) which causes the frequency converter (16) to control the door in accordance with a desired movement. The movement of the door is continously detected. The control and signal-processing means (32) compares the desired movement of the door with the detected movement, in order to emit an alarm signal (L) when the difference is too considerable. A switch means (28) thus blocks the power supply to the motor (12). A sensing means (31) senses whether the power supply to the motor (12) is blocked. The alarm signal (L) is repeatedly emitted in order to establish a possible malfunction of the switch means (28).

Title: Determining location of edges of sheets - activating threshold element when sensor is over edge and reversing movement of carriage by control
Inventor: TITKOV JURY SERGEEVICH
IPC: G01B21/02
Filed: 1991-09-16
Abstract: Initially, the carriage (2) is over the surface of sheet (1) and the regulator of distance between instrument (3) and sheet is connected. A signal proportional to the assigned distance passes to a differential amplifier (7). The carriage is moved horizontally along the sheet with an eddy current sensor (4) repeating irregularities of the sheet. During change of distance, the inductance is altered, changing the signal passing from the converting unit (5) to an amplifier (7) forming a discrepancy voltage to control a motor (10) acting through a reducer (11) and a rack (12) to adjust the height of the carriage. A sensor 4 registers the edge of the sheet and the resonance frequency of the oscillating circuit of the unit (5) falls rapidly, while the amplifier forms an increasing voltage. The motor turns, to reduce the distance from the instrument (3) to the sheet and the carriage si stopped. When the centre of the sensor is over the edge, voltage from the amplifier exceeds a set level and a threshold device (8) is triggered to pass a signal to a control system (13), reversing movement of the carriage. @(16pp Dwg.No.1/1)@.
