Abstract: A hail sensor is disclosed which contains a piezoelectric transducer positioned to produce an output signal when it is vibrated by a hailstone. In one embodiment, the transducer is mounted on a perforated member which is exposed to falling precipitation. In an alternative embodiment, the hailstone impacts a rebound surface and is deflected toward the transducer where an electrical output is produced.

Abstract: An amusement device is disclosed which contains a signal generator attached to a flexible member. When the flexible member is repeatedly waved, an oscillatory electrical signal is produced by the signal generator and supplied to a sound generator which produces sound which synchronously varies with the repeated flexure of the member caused by the waving action. The sound generator produces a first tone with respect to the oscillatory electrical signal and a second tone when the frequency of the oscillatory electrical signal exceeds a predetermined value.

Abstract: The present invention comprises reaction products resulting from the reaction of hydrazido-substituted or certain amino-substituted polymer stabilizers and cyclic dianhydrides, as well as the use of such products. The polymer stabilizers of the invention are useful for protecting a large variety of synthetic polymeric organic materials from the degradative effects of heat, light and oxygen. Some of the modifiers are flame retardants and many are metal deactivators in addition to their primary activity.

Abstract: A sensing device is disclosed which produces a response when the point of impact between an object and a member occurs at a preselected location on the member. When the member vibrates after being impacted by the object, an oscillatory electrical signal is produced by a piezoelectric sensor. Appropriate circuitry is provided for analyzing the oscillatory electrical signal and for producing a response if the object impacted the member at the preselected location. The sensing apparatus is particularly useful in athletics for determining whether a game object contacted the athletic instrument at its "sweet spot".

Abstract: An ultra-high solids, stable, liquid, highly alkaline caustic cleaner containing 40 to 80 weight percent total solids having 5 to 42 weight percent of an inorganic particulate material dispersed therein, such as an alkaline silicate, that is nonreactive and insoluble in the caustic of the composition.

Abstract: Ultraviolet light stabilizers are chemically bound to anhydride containing polymers or copolymers. The polymeric stabilizers are prepared by the reaction of primary amino or hydrazido-substituted UV absorbers with some or all of the anhydride groups of the polymer or copolymer to form pendant stabilizer substituted imide or amic acid groups. The polymer bound stabilizers are not lost from the polymer system by volatilization, migration, or extraction, even at high temperature. The polymer of this invention may be used as they are or as concentrates to stabilize other polymer systems.

Abstract: N-(polyalkyl-4-piperidinyl)imide containing polymer is prepared by blending together a mixture of a polymer containing anhydride functions and a 4-amino-polyalkylpiperidine or its 1-alkyl or 1-acyl derivatives and heating said materials in the blend, either prior to or during the blending step to the molten stage of the polymer; thereafter, heating said blend above 180.degree. C. for a sufficient time to form the product. All volatile by-products are removed either simultaneously or subsequently with the above 180.degree. C. heating step.

Abstract: Polymer bound stabilizer compounds are provided in which two or more different classes of stabilizers are chemically bound to anhydride containing polymers or copolymers. The polymeric stabilizers are prepared by the reaction of primary amino or hydrazido substituted stabilizers (i.e., antioxidants, light stabilizers, etc.) with some or all of the anhydride groups of the polymer or copolymer to form pendant stabilizer substituted imide or amic acid groups. The polymer bound stabilizers are not lost from the polymer system by volatilization, migration or extraction, even at high temperatures. The polymer bound stabilizer compounds may be used as concentrates to stabilize other polymer systems.
