Abstract: A non-woven fabric having a pattern defined by an array of discrete areas having a reduced fibre density but which are substantially free of perforations is produced by supporting a freshly wet laid web of the non-woven fabric on a porous surface and directing spaced jets of fluid against the unsupported side in order to displace fibres within discrete areas while maintaining in position a proportion of fibres that are within those areas and that are adjacent the porous surface. The fabric web may be supported on a Fourdrinier wire (1) and the jets of fluid (e.g. water) may be directed through the apertures in a perforated cylinder (6), the fluid being supplied under pressure from a water-knife device (11). The apertures in the cylinder (6) preferably have a cross-section that increases in the direction of the water jets.

Abstract: An automatic door installation with four traffic sensors mounted on the door jambs on opposite sides of the doorway opening and having radiant energy emitters and reflected energy receivers for sensing doorway traffic. Two sensors are employed to cover the exit or swing side of the doorway, a threshold sensor is employed to cover the threshold area and an entrance sensor is employed to cover the entrance side of the doorway. The entrance and two exit sensors each have a plurality of radiant energy emitters with angularly spaced beam axes to provide broad coverage areas intersecting the traffic path of travel. The emitters of the exit and threshold sensors are selectively deactivated as the door is swung between its open and closed positions to avoid sensing the door. The emitters of all four sensors are pulsed in a predetermined sequence and the sensor receivers are timely activated to receive reflected radiant energy from the respective emitter(s) only.

Abstract: An automatic control system for controlling the operation of a sliding door system employs an electric motor for driving the sliding door system. An encoder is mounted to the shaft of the motor for generating signals which are decoded to detect the operational position of the sliding door system. A clock paced sequential logic circuit produces speed and directions signals in accordance with the detected operational position to control the speed and direction of the electric motor. Means are provided for recording the last stop position and slowing the sliding door system prior to reaching the last stop position. Safety means are provided to de-energize the motor in the event of malfunction of the motor speed control. The system also includes a reduced opening stop feature and a means for automatically establishing a sliding door reference position.
