Abstract: A frame for a louver holds the louver below the ceiling surface, away from a light fixture. This helps to collimate the light rays and direct the light downward, thus preventing unwanted sideways glare. In addition, the use of a frame tends to hold the louver more securely in the ceiling framework. The frame is formed of Z-shaped members, with one arm of the Z resting on the T-bar cross-bar and the other arm supporting the louver. A stop along one side of the frame prevents movement of the louver in the frame. In one aspect of the invention, rotatable angle supports at the ends of the frame rotate from a vertical position for use during louver installation to a horizontal supporting position for supporting the louver in the frame.

Abstract: A method of reducing spillage when pouring liquid out of a container which includes the following steps. Firstly, place a free floating buoyant member into a resilient deformable container adapted for containing liquid. The liquid must be of greater density than the density of the member such that the member floats upon the surface of the liquid. The container has a fluid flow passage narrower than the dimensions of the member such that the member is prevented from exiting through the fluid flow passage. Secondly, exert a force to temporarily deform the container thereby reducing the volume of the inner cavity and causing the liquid in the container to press the member into a position sealing the fluid flow passage. Thirdly, invert the container thereby placing the container into a pouring position.

Abstract: A composite amplifier includes a discrete active gain element with a feedback circuit that provides for low drift and low offset, but which also has low noise, short settling time and high bandwidth. This is accomplished in part by providing an attenuator in the feedback circuit and by providing a voltage source for the source of the discrete active gain element. The feedback circuit is connected between the gate and the source of the active gain element and is responsive to a change in voltage at the gate to supply a voltage of equal but opposite magnitude to the source. The source has an impedance whose Johnson noise is less than the noise of the active gain element. A differential amplifier in the feedback is constructed in multiple stages with a first stage having lower gain than a second stage.

The first section and the second section are rotatably connected at a lower joint; the second section and the third section are rotatably connected at an upper joint. A telescopic member extends between a drawbar on a collector vehicle and the second section. The second section of the discharge spout rotates about the lower joint in unison with the drawbar to maintain spout positioning relative to the collector vehicle. The third section moves with the second section. The telescopic member telescopically extends and retracts in response to downward and upward deflections of the drawbar. A drive motor is provided between the second section and the third section.
