Abstract: The present invention relates to a hair treatment composition which provides an excellent finishing effect and superior protection against environmental, chemical, and grooming-associated damage. The compositions of the present invention comprise hydrolyzed protein having an abundance of anionic amino acids and in particular, sulphur-containing amino acids, as well as divalent cationic compounds, such that the anionic components of the hydrolyzed protein may effectively bind to the hair by means of cationic bridges. While bound to the hair, the sulphur containing amino acids in the hydrolyzed protein may serve as "decoys" for the effects of a variety of damaging agents. Compositions of the present invention may further comprise a vitamin compound which enhances these protective benefits.

Abstract: An apparatus and method is disclosed for determining geotechnical and geoacoustic properties of seafloor sediment wherein the undrained shear strength and dynamic shear modulus of such sediments can be quantified. Features of the deceleration profile of a seafloor penetrometer are compared to a data base of known insitu properties of seafloor sediments to determine a correlation between the features of the deceleration profile, such as maximum deceleration or jerk, and the seafloor sediment undrained shear strength. The damped oscillatory portion of the penetrometer deceleration profile, which occurs after plastic deformation and further permanent penetration into the sediments ends, is analyzed to determine the dominant or resonant frequency of the oscillations. This dominant frequency can be used to determine the seafloor sediment dynamic shear modulus.

Abstract: Cylindrical tubular substrates for an electrophotographic conductor can be made with different lengths from an injection-molded plastic cylindrical mother tube. The length of the mother tube is sufficient for the greatest desired length. The mother tube has a slanting inner surface which facilitates removal of the tube from the molding die, and non-slanting inner end surfaces which can be stepped. The desired length is obtained by cutting the mother tube across one of the steps. The resulting non-slanting inner end surface of the substrate provides a spigot joint for tightly receiving a flange.

Abstract: A system for non-destructively inspecting or testing for faults or damage in or beneath the surface of structures, such as debonds or delaminations in composite materials, or cracks, broken stringers, delaminations and the like in structures. High energy acoustic impulses are focused onto a sample point or local area for vibrationally exciting the surface of the structure under inspection. A laser Doppler camera system directs a laser beam onto the excited area and derives from reflected light energy information including time domain signals. A Fast Fourier Transform (FFT) is constructed for each sample point and an analysis made to set aside FFTs deviating from a preselected standard which represent damaged or other anomalous areas. The remaining FFTs represent an average or statistical FFT spectrum of the undamaged or fault-free area. The average FFTs and the deviating FFTs are then subtracted to provide a clear and unambiguous signal of the fault and other anomalous areas in the structure under test.
