A set of pickup truck protective pads for carrying long loads comprises a cab pad and a tail gate pad both of a configured elastomeric foam having preferably a tough skin or cover. The cab pad has generally a right angle shape in cross section and a beveled leading edge and the tail gate pad has generally a U-shaped cross section. Each pad has a hold down strap with clips on either side to secure ...

An automatic rate matching system is provided such that the delivery of bulk material is matched with the quantity of bulk material required by a process. An optical probe is used which determines the depth of material delivered into a hopper, prior to its retrieval for use in the process. The probe and assciated electronic components output a signal to a CPU which then varies the speed of a belt ...

A shoe consisting of an outsole and an upper, especially a children's shoe, is configured so that in a simple, inexpensive and unobtrusive way, it is possible to regularly accurately monitor or measure the distance of the toe tips of a wearer from a portion of the upper adjacent to the tip of the outsole to see in good time whether the shoe has become too small. This is achieved in that a transpar...

Waste water from the preparation of salts of dithiocarbamic acid is detoxified by acidifying the waste water to promote hydrolytic decomposition of organosulfur compounds, passing an inert gas through the acidified water to aid in expelling decomposition gases thereby increasing the decomposition rate, and, optionally, adjusting the pH of the resulting solution toward neutral.
