Abstract: A method of multiple dipping to make gloves with a clear wrist portion, which allows glove wearers to see through the transparent wrist portion and tell time with the gloves on, is disclosed. The method is applicable to all the common materials to make gloves, or coat gloves, via dipping: including natural rubber latex, nitrile rubber latex(carboxylated or non-carboxylated), polychloroprene latex, polyisoprene latex, polyurethane latex, polyvinyl chloride and their blends, or mixtures thereof. The invention provides procedures to make compounds, which are both transparent and opaque, as well as dipping sequences for the materials. Products, with the added feature of a transparent wrist portion, are provided without sacrificing performance and without increasing production cost.

Abstract: Transceiver head for a longitudinal Doppler speed indicator.Transceiver head for a longitudinal Doppler speed indicator with at least one pair of measuring axes.It comprises:a laser (1);polarization switching means (4) on the path of the laser beam;polarization separating means (5) on the path of the polarized beam that comes from the switching means;control means (5) for switching the switching means alternately from one state to another to direct the beam alternately to one measuring axis and then to another depending on its polarization state.
