Abstract: The hinge for mounting a closure panel on a vehicle body includes a body bracket mounted on the vehicle body and having a cam surface and an elongated cam slot. A panel bracket is mounted on the closure panel and has a cam follower portion slidably bearing on the cam surface of the body bracket to define a first cam arrangement. A torsion bar has one end nonrotatably mounted on the vehicle body and the other end nonrotatably mounted on the panel bracket so that the torsion bar torsionally biases the panel bracket and closure panel to a normal pivotal position relative the vehicle body. The portion of the torsion bar mounted on a panel bracket extends slidably through the cam slot of the body bracket to define a second cam arrangement. The first and second cam arrangements are arranged relative one another whereby upon pivotal opening movement of the closure panel, the closure panel is bodily shifted to avoid interference of the closure panel with the vehicle body.

Abstract: A one piece tube and microscope slide manipulative laboratory device, for use in clinical procedures employing a liquid test specimen. The device is significantly characterized by a normally upright tubular reservoir which is structurally equivalent to a normal test tube, and particularly of the type used for specific gravity measurements in a urine analysis procedure. Frangibly connected to the lower end of the tubular reservoir is a microscope slide chamber, comprising closely spaced opposed planar walls of optically transparent material. The upper portion of the slide chamber is adapted for flow communication to the lower end of the superposed tubular reservoir. Between the microscope slide chamber, and the tubular reservoir, is a transition member having a bore to allow the flow communication between the reservoir and the slide chamber.
