    Abstract: Root repelling pipe joints are used to prevent intrusion of root into underground pipelines. The joints comprise an annular member formed of an organic polymer mixed with an effective amount of a dinitroaniline. The dinitroaniline slowly diffuses from the polymer at a sufficient rate to keep roots away from the joints but sufficiently slowly to cause the protection for many years without translocating within the plants and kill them.

    Abstract: The device comprises a substrate (3) on which are placed a series of electrodes (1, 2) connected to a high-voltage source (6). Another electrode (8) is formed by a coating deposited on an insulating sheet (7) which is normally rolled. Application of a potential between the electrodes (1, 2) on the one hand and the electrode (8) on the other causes the sheet to unroll, and selective earthing of the electrodes (1, 2) permits controlled rerolling of the sheet (7). In this example, the electrodes (1, 2) are alternated and connected in two series to the voltage source (6). Two sheets attached to two opposite edges of the substrate constitute a roller blind shutter for a camera.

    Abstract: A detector system for sensing the progress of an ISV process along an expected path comprises multiple sensors (64, 52). The sensors relay electrical signals representative of temperatures in their vicinity to a signal processor (54) which in turn generates an encoded signal which identifies the particular sensor and whether the ISV process has reached the sensor's input port. A transmitter (59) provided with a self-contained power supply (48) and a switch (88) propagates the encoded signal. The signal processor and the transmitter are below ground at a location beyond the expected ending location of the ISV process. A signal receiver (82) and a decoder (84) are located above ground for receiving the encoded signal popagated by the transmitter, decoding the encoded signal and providing a human-perceptible indication of the progress of the ISV process.

    Abstract: In the inspection of cylindrical objects, particularly O-rings, the object (2) is translated through a field of view and a linear light trace (6) is projected on its surface. An image of the light trace is projected on a mask, which has a size and shape corresponding to the size and shape which the image would have if the surface of the object were perfect. If there is a defect, light will pass the mask and be sensed by a detector positioned behind the mask. Preferably, two masks (14, 16) and associated detectors (18, 20) are used, one mask being convex, to pass light when the light trace falls on a projection from the surface and the other concave, to pass light when the light trace falls on a depression in the surface. The light trace may be either dynamic, formed by a scanned laser beam (7), or static, formed by such a beam focussed by a cylindrical lens. Means are provided to automatically keep the illuminating and receiving systems properly aligned.
