A positive electrode 10 for a lead acid electric storage cell 24 is made by chemically preparing beta lead dioxide. The beta lead dioxide is then applied to a support structure 14 with a binder, or poured into a permeable, tubular container located about a current collecting rod. The negative electrode 26 can be made by compacting fine lead metal 30 about a carrier 32, and the fine lead metal migh...

An improved multipiece roof finisher, mounted over a roof and both side pillars of a vehicle, is disclosed. The finisher is divided into three parts: a center finisher over the roof, and two side finishers which cover the side pillars. The center finisher is connected to the side finishers by connecting means.

A method and an apparatus for measuring the wall thickness of a plastic article, particularly of a hollow rotation-symmetrical plastic article. According to the method, the wall of the plastic article is subjected to infra-red radiation and the intensity of, e.g., the continuously transmitted radiation is measured at preselected points, said intensity being a function of the wall thickness to be m...

An improvement in an x-ray apparatus used to obtain diagnostic x-ray images is described. The improvement includes a monitoring means, 10, for monitoring a physiological process such as cardiac or respiratory cycles.
