Abstract: An illuminated magnifying device comprises an elongated magnifying lens, a light source, and an elongated light pipe disposed along the magnifying lens operable to receive light emitted from the light source and direct the light outwardly from the light pipe and distribute the light substantially evenly onto an object surface to be viewed

Abstract: A pressure control accumulator for hydraulic brake systems includes a housing having a brake fluid port and a cavity communicating with the port. A staged series of resilient membranes is disposed within the cavity for nullifying hydraulic brake fluid pulsations over a wide range of pressures. The staged series preferably includes a resilient diaphragm disposed adjacent the port for nullifying hydraulic brake fluid pulsations at low and normal pressures by itself and maintaining the brake fluid on one side of the diaphragm, and a resilient membrane disposed remote from the port and normally spaced from the diaphragm, the diaphragm and the remotely-disposed membrane cooperatively nullifying hydraulic brake fluid pulsations at high pressures by providing a plurality of resilient resistances in series. The remotely disposed membrane may be a second diaphragm.
