Title: Control of grafting processes
Inventor: HAGGER JOHN MICHAEL RICHARDS
IPC: C08F255/02
Filed: 1988-02-26
Abstract: A continuous-flow process in which side-chains are grafted to a thermoplastic base polymer, especially the grafting of side-chains suitable for hydrolytic crosslinking, is controlled with reference to a measured rheological property of the polymer. The melt property may be a true viscosity or a viscous modulus but any measurement that generates a number that correlates with viscosity can be used. The measurement is made on material at a place in the flow line where at least a substantial part of the grafting has taken place, preferably where it is (or ought to be) complete, and at least one reagent concentration or process condition is adjusted to maintain the measured property within limits that are preset, either absolutely or with reference to other prevailing conditions. The grafting of polyethylene with vinyl trimethoxy silane in an extruder is described.

Title: Conduit constriction means
Inventor: SANDERS ROSS PETER
IPC: F42D1/18
Filed: 1988-10-14
Abstract: A means for the constriction of fluid movement in a conduit comprises a tubular wall-gripping member which is freely movable within the conduit but which is capable of lateral expansion to grip the conduit wall. The wall-gripping member has an exterior (wall-gripping) surface and an interior surface which is so shaped that, when the wall-gripping member is prevented from moving in the conduit, the action of the fluid, either directly or indirectly, on the interior surface causes expansion. In a preferred embodiment, a tube 2 is segmented into four segments 4 which are secured by circumferential elastic bands 5. The interior surface is frusto-conical and the action of fluid on a similarly-shaped frusto-conical vessel 1 placed therein causes expansion. This means is particularly useful in the explosives industry for providing "air-decking" in vertical blastholes. <IMAGE>

Title: Self-checking light curtain system and method of operation
Inventor: BLAU DAVID
IPC: F16P3/14
Filed: 1991-01-04
Abstract: A light curtain system and method of operation which detects the intrusion of objects into a protected zone. The system is characterized in having an inherent self-checking mode of operation by logic circuits which analyze data signals from both the LED light transmitters and phototransistor receiver circuits. A shutdown signal is generated if the logic circuit determines that light is not received in a selected channel at the time that the LED is strobing light exclusively for that channel. The system further provides a relatively simple and inexpensive method of selecting and amplifying the LED transmitters and PT receivers. In the circuit each PT acts as a switch which selects itself, and a single amplifier is employed for a plurality of the channels. The circuit further provides for the concatenation of groups of amplifier/PT circuits into a longer chain using a single diode.
