Title: Method and apparatus for high resolution analysis
Inventor: CROWE BENJAMIN S
IPC: G06F17/14
Filed: 1991-09-17
Abstract: The present invention relates to analytical methods for determining the composition of a material that undergoes a transition as a function of a driving variable. As applied to thermogravimetric analysis (TGA), a first preferred embodiment comprises (Z) decreasing the heating rate when deviations from a baseline signal are detected; (2) establishing a minimum heating rate; (3) forcing the heating rate to a predetermined maximum whenever the rate of change of the weight change with respect to the temperature falls below a predetermined value; and (4) adjusting the heating rate according to the rata of change of the weight of the sample to track a predetermined rate of change of the weight of the sample. A second preferred embodiment comprises (1) selecting either a high-productivity or a high-resolution mode; (2) in both modes, controlling the rate of temperature increase according to a function containing an exponential term, wherein the argument of the exponential term includes the percent weight change per unit time of the sample; (3) in the high-productivity mode, choosing the function so that when the percentage weight change per minute of the sample is small, the heating rate approaches the maximum allowed heating rate, and when the percentage weight change per minute is very large, the heating rate approaches zero; (4) in the high-resolution mode, choosing the function such that the heating rate is held at almost zero during a transition.

Title: Apparatus for disintegrating flexible packing materials
Inventor: MENGES WILHELM
IPC: D21B1/02
Filed: 1991-12-24
Abstract: Abstract An apparatus is described for reprocessing, i.e. disintegrating, used packing materials, for example unsorted domestic waste paper.  The apparatus consists essentially of a first comminuting aggregate (14), a following trough-like housing (2) with agitating mechanism (4, 6) rotating therein and a further comminuting aggregate (18) arranged in the material exit well (16).  The apparatus is further provided at its lower end with a heavy trash collecting chamber (26).  The comminuting aggregates (14 and 18) are replaceable and depending upon the working requirements selection is possible between purely cutting, more chopping or also disintegrating tools.  The first comminuting aggregate (14) serves to comminute the largely sheet-like raw material to a conveyable piece size whilst the second comminuting aggregate (18) serves essentially for fine comminution and disintegration of the material. In the intermediate trough cleaning of the material can take place, and a rinsing liquid circulation can be employed via the connections (38, 34, 36 and 28).  In this case low-density operation is provided.  The apparatus can however also be operated in the high-density range and then a disintegration can start in the trough (2) itself.  The material leaving the apparatus is prepared in such a manner that it can be separated into its components to be further treated by means of sieve sorting devices.

Filed: 1992-09-14
Abstract: A unique plastic retainer is disclosed having a pair of axially spaced cylindrical rings. Retainer arms for retaining an upset portion of a tube within a housing bore extend from a rear ring, and a plurality of webs connect the front and rear cylindrical rings of the retainer. When a tube is initially inserted into the housing bore, it contacts an inner periphery of the arms. The retainer then moves axially forwardly within the bore for a small distance until the forward ring abuts s seal package within the housing. Further movement of the retainer is then prevented, and the upset portion of the tube causes the arm to flex radially outwardly at a flex point in the rear ring. The upset portion may then move axially beyond the arms into a fully connected position within the housing.

Patent CA-2088244-A1 (CA)
Title: Adhesive compositions
Inventor: MARTIN ROBIN A
IPC: C09J175/04
Filed: 1991-05-08
Abstract: Heat curable adhesive compositions which include liquid polybutadiene polymer, powdered sulfur, organic accelerators and inert fillers are improved by adding blocked polyisocyanates or capped polyisocyanates. The addition improves resistance to "popping" of the cured or uncured adhesive when exposed to high temperatures, e.g., spot-welding. The addition does not alter the beneficial flow properties and rheological properties of the adhesive. The adhesive is particularly useful on zinc coated steel, both electroplated zinc and hot-dip galvanized zinc coatings. Inclusion of zinc borate will activate the cure accelerators and retard the "popping" phenomenon at welding temperatures.
