Disclosed are films or sheets comprising a crystalline propylene polymer composition which is comprised of, by weight, (A) from about 30 to 65% of a copolymer of propylene with a C.sub.4-8 alpha-olefin containing from 80 to 98% propylene, and (B) 35-70% of a co- or terpolymer of propylene with ethylene and, optionally, a C.sub.4-8 alpha-olefin having an ethylene content of 5 to 10% when ethylene is the sole comonomer and an ethylene content of 0.5 to 5% and a C.sub.4-8 alpha-olefin content of 1 to 9.5% when both ethylene and a C.sub.4-8 alpha-olefin are used as comonomers. Coextruded films or sheets and laminates wherein at least one layer is a film or sheet as described above, and films or sheets of blends of the propylene polymer composition and an olefin polymer are also disclosed.

A method of forming a laminated piezoelectric structure is disclosed wherein a plurality of polarized piezoelectric films of vinylidene fluoride and trifluoroethylene are solvent welded together. The solvent welding solution comprises a copolymer of vinylidene fluoride and trifluoroethylene and a suitable solvent. The transducers produced from such a laminated structure are also disclosed.

A device for measuring the speed of a moving object has first and second impact detectors separated by a preselected known distance and disposed in the path of movement of the object. As the object strikes the first and second detectors, the detectors each produce a signal. The signals are separated by a time interval indicative of the distance between the detectors. The elapsed time between the signals is measured by a counter device, and the speed of the object is calculated by a programmable device.
