摘要:
A nectar feeder for birds. The nectar feeder has a container for storing nectar feed. A base tray is attached to the container and connected in fluid communication with the container. A float is positioned between the container and the base tray. A ball is positioned on the float. The ball regulates the fluid communication between the container and the base tray. In operation, the nectar feed flows through the container and into the base tray until the float rises to a level where the ball prevents fluid from flowing into the base tray.

A bird feeder has a body member, a base, and at least one feed port member. The body member is used for storing bird food having a top end, a bottom end and a sidewall with the sidewall of the body member defining at least one feeding aperture. A base is attached to the bottom end of the body member to prevent bird food from exiting the body member. The at least one feed port member is interfittingly engaged within at least one feeding aperture. The port member includes a frame member and a mesh insert attached to the frame member. The feed port member is releasably secured within the feeding aperture of the body member. In operation, the feed port member can be easily removed from the body member for easy cleaning or adapting to a particular bird feeder construction.

Bead-form expandable styrene polymers containing a styrene polymer having a mean molecular weight (weight average) of less than 130.multidot.10.sup.3 and a steep high-molecular-weight flank of the molecular-weight distribution curve, and 0.15 to 1.5 mol of a C.sub.3 - to C.sub.6 -hydrocarbon as blowing agent, and, if desired, customary additives in effective amounts, are distinguished by a particularly high expansion capacity.

The present invention relates to a method for ink-jet printing with a printing ink containing a pigment preparation containing(a) water(b) a dispersing agent, and(c) at least one pigment consisting of a barbituric acid substituted by radicals containing methine or azo groups or a derivative thereof, preferably present as a salt or a complex, a solid solution, an inclusion compound, or an intercalation compound.

The present invention provides novel apparatus for aerating a body of liquid. The apparatus includes a diffuser shell in the form of a substantially tubular, elongate body of a relatively rigid, gas permeable material such as fine pore polyethylene. The diffuser is closed at one end by a first end cap and at the other end by a combination second end cap and gas inlet assembly. The latter is adapted for connection to a source of pressurized gas. Disposed within the hollow interior of the diffuser shell is an elongate housing for containing a suitable ballast. The diffuser shell and ballast housing are dimensioned so that there is an interspace between the external periphery of the ballast housing and the inside of the diffuser shell. The ballast housing is supported at one end by the first end cap, and at the other end by the second end cap and inlet assembly so as to maintain the interspace between the ballast housing and the diffuser shell. Conduit means are used to connect a source of pressurized gas to the inlet assembly.

The invention relates to an electronic distance measuring apparatus for surveying, e.g. for measuring the distance from the apparatus to an object. The apparatus comprises: a) an objective lens (101), defining an optical axis (OA), b) at least two sources (111, 112) of structured light for transmitting beams (λ1, λ2) of separate wavelengths towards said object, said beams on reflection from said object received by the objective lens (101), (c) at least two receivers (141, 142) arranged outside a beam path (109) as defined by the objective lens (101), and adapted to receive said received beams (λ1, λ2) of structured light. Optical means comprising at least two dichroic surfaces (121a, 122a) are each arranged at a tilt angle (α1, α2) with respect to said axis (OA), said optical axis (OA) passing through said surfaces, at least one of said dichroic surfaces arranged on a plate (121, 122), said at least two dichroic surfaces (121a, 122a) adapted to reflect at least one of said received structured light beams (λ1, λ2), respectivly, towards said receivers (141, 142).
