摘要:
An anti-theft device is disclosed for providing an alarm in response to unauthorized movement of an article of property, for example the cash supply of an automatic teller machine through a localized field. The device is adapted to be affixed to the article and comprises: motion detection means (24), field detection means (26); and means (40) responsive to the motion detection means and the field detection means, for triggering an alarm device (22,42) such as a smoke generator if, and only if (a) the field detection means detects the localized field and thereafter ceases to detect the localized field, and (b) the motion detection means detects motion of the article during a predetermined delay interval following the time at which the field detection means ceases to detect the localized field. The invention also includes an anti-theft system for use in conjunction with an automatic teller machine.
摘要:
A reinforced concrete system provided with cathodic protection has a metal mesh anode embedded in a conductive cementitious composition. The use of a conductive cementitious composition around the anode mesh results in a reduced amount of acid degradation of the mortar around the mesh.

摘要:
Polymer additive concentrates comprising (a) between about 10 and about 80 weight percent of a polymer additive; (b) between about 2 and about 50 weight percent of an absorbant material which is a consolidated blend of spurted polyolefin pulp treated with a wetting agent, and wood fluff pulp; and (c) between about 5 and about 80 weight percent polymer, possess unexpectedly higher additive loading as well as exhibiting admirable properties when employed in polymers which are extruded into clear films. In addition, a process for manufacturing such concentrates is described.
