Abstract: Water is supplied from a preselected depth in a body of water by an intake held at the preselected depth by a stem connected to a float which rides near the surface of the water. The stem is weighted to maintain a desired orientation of the device in the body of water. A guide is provided in the body of water to maintain the horizontal position of the intake means.

Abstract: A wind powered device incorporates a solar furnace and vortex generator to provide additional power and boost the efficiency of the complete system. Two concentric dome assemblies connected by a centrally located shaft are connected to a base with bearings capable of rotating the whole assembly 360.degree. about a vertical axis to allow it to turn into the wind. The two domes form a furnace, an inner dome providing insulation for a solar boiler and an exterior dome refracting the incoming sunlight onto the solar boiler. The solar boiler is located at the center of the inner dome and generates steam to drive fans positioned at the poles of the outer dome. The outer dome also functions as a wind powered rotor. Inlet vanes at the periphery of the dome are open to the atmosphere. The exterior of the dome is provided with trapezoidal or curved channels at regular distances parallel to the path of rotation. These channels effect lift by the venturi effect. They also channel the light to the center of the dome.

Abstract: The displays are provided for assisting a pilot in making critical decisions during the takeoff roll of the aircraft. The first of the displays includes four pointers which indicate, respectively, the maximum available acceleration of the aircraft, the minimum acceleration required to achieve a velocity V.sub.2 at 35 feet above the end of the runway with all engines operating, the minimum required acceleration which will allow the aircraft to accelerate to a critical velocity with all engines operating and complete a legal takeoff after loss of an engine at the critical velocity (V.sub.1), and the actual acceleration of the aircraft. The second display indicates the ability of the aircraft to safely complete the takeoff if an engine were to fail and the ability of the aircraft to stop safely if the pilot were to decide to abort the takeoff.

Abstract: A heat exchanger useful for supplying infusates over substantial distances uses an extrusion which provides a central tube for carrying an infusate and two outer channels for carrying a heat exchange fluid. A first of the channels carries the heat exchange fluid from an inlet end to an opposite end, and the other of the channels returns the heat exchange fluid to the inlet end. An end cap at the inlet end is easily connected to a source of heat exchange fluid and communicates with the channels. An end cap at the opposite end receives the heat exchange fluid from the first channle and redirects it to the second channel. Both of the end caps have connectors for facilitating connection with lines from a source of infusate and a patient.

Abstract: A rigid polyisocyanurate foam suitable for holding stems of artificial flowers is a substantially closed cell foam having a density of about 1.7 to 2.9 lb./cu. ft. The foam is made by mixing components A and B in a ratio of B:A of about 0.2 to 0.6. Component B is a mixture of 100 parts by weight of polyester or polyether polyol, 0.5 to 5 parts by weight of potassium octoate, 4 to 10 parts by weight of water and 0 to 8 parts by weight of green colorant. Component B is mixed with 250 to 500 parts by weight of polymeric diphenyl methane diisocyanate (component A), and the resulting mixture is poured onto a substrate, which may be a conveyor or a mold box, for foaming in a substantially free rise step with a cream time of about 5 to 20 seconds. The conveyor is preferably heated to about 100.degree. to 150.degree. F. The foam is cured before cutting.

Abstract: A golf club head characterized by: (1) a longitudinal division of the principal mass, (2) a high polar moment of inertia to mass ratio, (3) a striking surface structure with a first order resonant frequency of at least 2000 cps, (4) nearly equal yaw and pitch polar moments of inertia, (5) symmetry about and positive identification of longitudinal axis and sweet spot, (6) a striking surface which lies well forward of the neutral axes, and (7) a point of application of the stroking forces on the longitudinal axes and forward of the center of gravity.

Abstract: An architectural tile is made of a panel capable of overlapping a laterally adjacent panel as well as a longitudinally adjacent panel. The panels include a first part for being secured to a wall or roof and which includes a locking ridge for engaging a second part of an overlapping panel. The locking ridge terminates below the upper edge of the panel to allow a longitudinal overlap of the panels.

Abstract: An aerosol container is particularly useful for a razor wherein the container serves as part of the handle for the razor. The container includes a combination cap/actuator which dispenses material when depressed. The cap/actuator may be depressed only when placed in a selected rotational position, other rotational positions causing engagement between a shoulder on the container and a skirt on the cap/actuator to prevent depression of the cap/actuator.

Abstract: A hand tool for holding a terminal in an insulating terminal block includes first and second jaws pivotally connected to each other, a channel or receiving the end portion of the terminal in a nose portion of the first jaw and a member attached to the second jaw for deflecting a tabbed portion extending outwardly from the end portion of the terminal so that the terminal is held in the insulator. The end of the terminal is entered in the receiving channel in the first jaw and the jaws are pivoted to a closed position. The tabbed portion of the terminal is deflected to prevent withdrawal of the terminal from the terminal block.

Abstract: A dual wavelength fiber optic monitoring system utilizes the principle of conservation of throughput to permit the use of a plurality of transducers illuminated by a single source unit. Redundancy is provided by using a plurality of sources and detector units and by the use of optical couplers to transmit the light beams between these elements.
